Revo OS.28 ABmods top speed 2 72 mph

[@CarsnStuff]

thing seriously sounds perfect. the OS motors never fail to impress me. any time i've had experience with them im just amazed. good video man.

[@CarsnStuff]

@Memer Dreamer true true, its really the type of engine for people who are die hard hobby enthusiasts. Personally i enjoy the hobby but i too have never spent that much on an engine. frankly most of the os engines i've had were from things like second hand that needed a rebuild or one time at a yard sale and they had no idea about rc cars and it had a nice os engine in it. But i've never bought a new one. I remember at the time of this comment i had a revo that i did a .28 but i just got one of those chinese ones and it still was an impressive and fun engine sounded great too.

[@MikePeperni]

@angelsofme HPI tremor wheels with HPI Phaltline tires, we modded the tires to handle those speed, we used fishing line around the tires in the grooves glued in tire glue.

[@MikePeperni]

19t clutchbell you can get them almost anywhere, we used a 1/8 scale clutchbell for this, and the spur gear is a robinson racing 34t metal.

[@HPISFBankrupter]

the excitement when you saw 72 was priceless... Good stuff Mike

[@Rustler883]

Nice video again =) You always have BEAUTIFUL tires/wheels on your R/C !!

[@ABModsBlevinsTuning]

Thats what im talking about Mike!!! GREAT JOB! AB Mods Racing Engine FTW!!

[@minitruknchris]

Awesome bro...Very nice. Im awaiting my new Exceed Rc Mad Warrior .28. Cant wait to break it in.

[@MikePeperni]

@mstreamer9991 It will on 18t36t only yes, but not much over 60, we used the slayer internal gear ratio to be able to run over 70. Thx man :)

[@MikePeperni]

@HPISFBankrupter lol thx! on that last run i started the run a little further and i was thinking may be a 70, or 71 if lucky, but it went 72, and at the other place with my friend holding the radar so he can turn around as it continue getting speed i think it could hit 73mph on that gear :)

[@MikePeperni]

@aonixer6 I used zip ties to keep both rocker closer together keeping it really low,as low as i want, make sure to keep some suspension travel. :)

[@MikePeperni]

@iuliuspeverini the axial .28 spec 1 is a low grade engine, stock it is pretty slow compared to a OS.28, but in a revo it will still feel powerful, with the drag mod it should wake up its top end, but it will not be powerful like a drag mod OS.28. I think he make a deal with the break-in...not sure.

[@revorocks123]

@MikePeperni Well, touch wood I've never had any transmission problems apart from stripping the out put gear (the weak one with the reverse kit). I did a forward only conversion after that and have had no more problems so far. I bet knowing my luck it will break now next time I take it out! Can't afford RR gears, although they are very nice. I think I'll fiddle with the engine mount, try and make it more adjustable and sort out this mesh. Keep up the great videos!!

[@MikePeperni]

@FRYEGUY247 it was not lean, im thinking about either wheel spin making the tire bouncing or the rear diff partialy stripping or the slipper clutch losing grip.... other than that i have no idea :)

[@MikePeperni]

@Jtaullie77 You can get them from most LHS, but you can get them on towerhobbies, hpi tremor wheels with phaltlines tires, they come pre-glued, or seperatly, get the black rims, the chrome fluke and the tire will unglue... :)

[@MikePeperni]

@MrBigjay9 you can find a 22t made by axial, you can get it on ebay, or in most LHS. the spur gear you can go down to 34t (unless the ymake smaller now) also check on ebay...

[@revorocks123]

@MikePeperni Ahh that might be it then. I was considering a steel spur gear but I've heard so many horror stories about people destroying diffs and gearboxes when they get a steel spur. I guess it should be ok as long as you have the slipper set up properly though, I need to get a 20T hardened clutch bell first though as the one I has is just a standard steel one. Cheers

[@MikePeperni]

@revorocks123 Geared like that im surprised you didnt stripped the 2nd speed gear in the transmission, the plastic spur gear is supposed to handle more than the 2nd speed gear in transmission, i never stripped a spur, but did strip the 2nd speed gear 4-5 times. Now we run the robinson racing transmission. :)

[@therccelebrityspeedfresh5393]

i got my jato 3.3 up to 80mph i made the news people. i took my jato 3.3 on hwy 59 south driving my truck controlling it at the same time going 80mph

[@thisguythatguy896]

That's awesome!! Lipo speeds out of a revo :) nice work

[@MikePeperni]

Yes, just the gear on what we could call ''final ratio''id need to find the exploded view to say wich one exactly been a long time since i didnt played with RC cars.

[@daleyb93]

the only thing weird about that sounds is how cool it sounded!

[@FRYEGUY247]

that sound could be a airleak or to lean but dam you just keep beatn the record lol love that revo

[@MikePeperni]

@mstreamer9991 Thx! the engine can rev pretty high with the mods though, i mean high rpm power not just high reving :)

[@NSWNY]

If you were breaking 60 with an 18/36 gear then your engine must rev pretty frickin high. Either way, I am quite impressed Mike.

[@RCSMAXX]

hey what percent of fuel u running just curious? plus like your video man keep them coming. oh yeah also what brand of fuel well laters

[@revorocks123]

Holy crap that's quick! I'm trying for fairly high speed with my Revo but I could never touch that kinda speed. I'm running a Picco .26 with 20/36, still wheelies which is cool but does strip the spurs occasionally. Do you think that's from the torque, or just a bad mesh. The stock mount for the .26 is pretty crap...

[@alberteyde8024]

thanks for the advice. I like your revo vids.

[@MikePeperni]

Thx! and np :) i wish i had more money at that time, we would have gone faster, the rear was too light and the road too bumpy.

[@MikePeperni]

@daleyb93 hehe yeah it was a lot of fun, with all the building it sounded echo it was nice :)

[@MikePeperni]

@nevrnuftorq Thank you! should do more test soon :)

[@NSWNY]

@MikePeperni I was gonna say, you must've used the slayer gears. Nice job bro.

[@MikePeperni]

@ABModsBlevinsTuning Thx Adam!! +1!! that engine is a monster! :D

[@MikePeperni]

Not really, i still have that revo, havent run anything in the past 2 year, but plan to do some more runs this next summer. :)

[@MrBigjay9]

please tell me where i can find the bigger clutch bell and smaller spur gear...asap....thanks and love the videos

[@MikePeperni]

@SkiBmd Merci!! Un bon moteur et un bon setup :)

[@jjlwis]

that's awesome that you can hear it down shift!!!

[@MikePeperni]

I think it was less than 225F, geared wider we got 75mph and it wa around 245F after 2 runs with a lot of room.

[@MikePeperni]

@RCSMAXX i used blue thunder HP8 30% 8% oil. :)

[@MikePeperni]

@jssouthtx No its a nitro revo, my friend sold his E-revo :) thx!

[@MikePeperni]

@x7Chaosbullet I bought the truck and parts with my top speed buddy, make it easier to buy everything :)

[@boomstickcharlie8480]

the last run it would have run leaner because low fuel making it a little faster

[@MikePeperni]

@MrGhostrider1986 Thank you! yeah next time its all out! :)

[@MikePeperni]

Theres no pullstart for the OS.28 (at least there wasnt at that time) its bumpstart, i use a handheld bumpstart. :)

[@MikePeperni]

@aonixer6 yeah thats what we used, i really like it. :)

[@MikePeperni]

@Revomad1 larger clutchbell= more top speed and need more power to keep the same rev.... I also run the slayer internal ratio wich equal to a larger gearing than 22t 34t with teh revo ratio. I tried 22t 34t with the slayer ratio and its a little too much for the engine, ill test 20t 34t and it should be optimum. with the Picco .28 i hit the curb where im standing at 65mph.... it was not too bad but all foam tires were broken an a few parts cost 50$ to repair. :)

[@MikePeperni]

salut, oui je le possede encore il est chez un de mes potes, celui que je roulais toujours avec dans les video.

[@federicomaggi3371]

In argentina i can onely get novarrosi p5 ; os 21 tm or alpha .21 ryan lutz ... the os cost a lot more than the others. Os is a big diference vs nova or the alpha?

[@alberteyde8024]

hey mike, did u have any challenges installing the os .28xz to the traxxas big block mount?

[@MikePeperni]

I think i had to grind the mount slightly or the engine block , not sure... and moving the transmission forward just a bit to align the gear, just ''oval'' the mounting hole of the transmission on the chassis :) And may be play with the throttle linkage a little, like modifying trhe shape of the little arm with a knife to make it move more freely...

[@alberteyde8024]

I'll see what I can do to beat your record. I have a revo 3.3 with a modded roma, and a revo 2.5 with a nova flash .21. I'm tinkering with the gearing and trying to cut weight on both. they are both running just under 60 mph right now. I got a long way to go....

[@MikePeperni]

The most important thing is the tires, you need tires that doesnt balloon. Good luck! :)

[@Marioplus]

Hello ,i have an Picco 28 to put on Traxxas Revo but It doesn't fit because Is too long. Can i cut It? The base Is Big block, Before It was an Picco 26 Thank you

[@IAP_mkt]

hey mike, sorry i ask you all these questions but i went in the ab mods site and i decided to get the Axial .28 Spec 2S, the engine break in and the drag modification.But i don't know if to get the break in with modification or the normal one? and why the one with modification is cheaper? and do you think thats a good angine for revo? ok this is last question lol. thank you

[@MikePeperni]

@elieldiaz thank you! :)

[@chrisvoutsinas1477]

I like those wheel where did you get them at and what Scale truck are they for

[@Bikini_ST]

proline street rage i got s some for my rustler

[@MikePeperni]

not really, no matter the tune, with that kind of gearing it will eventualy start to get hot and be on the lean side no matter what you do (if you are trying to achieve a good top speed) i could tune for the engine to stay even cooler but it would not run that great. And if you are talking about when the car is not moving and the idle is not equal, thats me holding the throttle slightly to make sure its not stalling...

[@offroadrc]

good vid. that car is FAST

[@alberteyde8024]

I see u went with the traxxas cvd's. is there an advantage to using those over the stock shafts? are they durable? I've got a few revo projects going on at the same time. one with an ABMODS novarossi roma.

[@MikePeperni]

For top speed its a must to keep things free rolling (stock one can be unbalanced and they are too big..) We never broke a set of cvd's so i guess its a good thing to get. Stock ones are okay if you dont abuse even with big power.

[@easyduzzit1358]

hey @mikePeperni what do you mean you used slayer internal gears? do you mean inside of the transmission?

[@MikePeperni]

@STdemoniac yes :) thx!

[@MikePeperni]

@revorocks123 It could be the mesh, and the fact the chassis flex under power. I suggest you to run an integy metal one, despite the fact its integy, their spur gear are reliable. :) Thats what we run. 34t integy metal spur gear. Goodluck! :)

[@kaycee9337]

Hey Mike did you strap it down to lower it that's how I have mine. Also what do you think about the picco 28 boost I have that in my Revo 1834 wide ratio gears it only gets up to 66 miles per hour what do you think about that picco boost. I think it's a beast and I picked up the Slayer gears to see the difference I'll probably throw them on next week but those are my two questions did you strap the front end down with zip ties and what do you think about the picco Boost 28

[@MikePeperni]

Hi, yes i strapped the rocker arms together wit ha zip-tie just enought to have the a-arms parralel to the ground and keep some suspension movement, i dont know the Picco .28 boost but i guess it is powerful enought to get it to 70 with the right setup :) WHat tires are you running?

[@MikePeperni]

avec la carrosserie comme la photo du debut a l'endroit ou la photo a été prise ont a atteint 75mph mais le derriere du revo était trop leger c'était dur a controler yaurait fallu un petit aileron , dapres moi 77mph max

[@angelsofme]

@MikePeperni What type of tires and rims are you using in this video?

[@easyduzzit1358]

@MikePeperni i have the same engine with revo, is it a direct drop in?? if not what mods did you have to do to get it fitted?

[@MikePeperni]

+Eddie Deschamps i used the traxxas big block mount, you may need to grind the mount slightly to fit the engine or to fit bigger gears depending the gearing you have or want to run, if the gears dont align you can enlarge the holes on the chassis for the transmission, just make them oval, it give adjustement to move forward or backward, not sideways. Other than that i used the traxxas big block header and a 086 tuned pipe, you just need to make a pipe hanger. I think thats mostly what ive done to fit the engine, you have to remove the roll bar on top as well. If you want to get crazy power on top end ABmods have the recipe, i helped a lot during the testing and its just completly nuts the power this engine hide in stock form, even stock its pretty good though! :)

[@michaellovett2568]

What kind of flywheels and clutch bell set up are you using and can I have the part numbers

[@MikePeperni]

Michael Lovett I think i used an ofna big block flywheel and purple clutch shoes with strong springs, and for this run i think its a 19t clutchbell, we got it up to 75mph on a longer and cleaner road and could gone faster it bcame unstable..., i did a quick search (been 4-5 years i havent touched a RC car...) heres the clutch www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXKKF6&P=7The flywheel: www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXDSW4&P=7Spacers: (always good to have) www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXNXG1&P=7Flywheel nut: www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXNUM6&P=7For the clutchbell, if you dont use fishing on the phaltline they will expand and use a 17t-18t maximum, if you use the fishing line around the tires use the 19t, you can use an HPI one or robinson racing one for big block. It also depend what engine you are running. Keep in mind you might need a little grinding here and there to make it work, i dont remember if its on this setup but i remember in one setup i had the enlarge (oval) the transmission mounting hole on the chassis to move the transmission forward to align the clutch bell and spur. (i recommend using the robinson racing metal gear set for transmission, i remember there was a critical part at least to change i dont remember wich one.... just get the completet kit you will be sure :)

[@federicomaggi3371]

I have to chnge mine 3.3 and not sure to buy a big block or convert to electric... i like aceleration and no more than 60 mph... what do you think in mine better choice? Tks

[@MikePeperni]

Federico Maggi If you want to go electric, id suggest you to buy a complete new truck instead, it will be better in the long run, if you jump your truck and land upside down it will be dangerous with a big block, the ead stick outside more, but still Worth it for the power, an OS.28 would suit your need in big block department, and they react well to modding as well, they become real beast, i got my revo up to 75mph with this engine and it could gone faster the rear was too light at high speed and became unstable..... If you dont jump then go with a big block, if you have the money and never had an electric you will be amazed by the power and ease of use. If you never seen a .18TZ in action, id suggest you to get this engine and get it modified professionaly by someone like ABmods, get the drag mod and you will be very happy, its small, powerful and run very good, and you dont need to get a different mount, i think you just need to grind a little part of it to get it to fit at worst (not sure been a long time). I could hit 52mph on stock 15t/38t gearing with a drag modded .18TZ instead of 43-45mph with the stock 3.3

[@elieldiaz6999]

great speed!! nice rims

[@devine3676]

Nice as run buddy. Do u sell that os engine with those mods or how can I get one? I run a modded LRP 28 with the 9886 Novarossi pipe and header

[@MikePeperni]

Thx :) best run was 75mph, my friend still own the engine, i doubt he would sell it, i modded the engine but ABmods (www.abmods.com) know the timing and can mod it for you, just ask for the drag mod :)

[@devine3676]

Thanks bud.

[@Ramipuchi]

Hello Mike What are other modifications you applied in your Revo?

[@MikePeperni]

Rama Pucci CVDs, lower suspension using zip-ties on rocker arms (keep arms level to the ground make sure theres still suspension travel) slayer internal gearbox ratio, metal gear set for the rest of transmission, removed unecessary stuff on the chassis to shave some weight, adjusted toe/camber to keep it straight, modded tires using fishing lines to prevent them from ballooning, modded engine, thats about it i think.

[@shadislandguy1424]

[@easyduzzit1358]

hey @mikePeperni what setup did you run with inside the transmission??

[@alberteyde8024]

Which clutch are you using? Which collet first the flywheel?

[@MikePeperni]

I think it was an ofna clutchbell and clutchshoes, you need to oval the holes on the chassis to be able to move the transmission forward a little to align the gears.

[@easyduzzit1358]

@MikePeperni do you know the exact gearing you used inside of this transmission??

[@MikePeperni]

+Eddie Deschamps It was the slayer intenal gear ratio, and everything else was upgraded with the robinson racing gear set. with 19t 34t clutchbell/spur but you need to gear according to the tires and engine... :)

[@alberteyde8024]

Hey Mike. So I had AB Mods work on a .28xz for me. I’ve been trying to break it in and I’ve been driving it around and I just can’t get the engine temps above 150. I have tried running it on the lean side just to get the temps up around 200 but it won’t get above 150. I tried richening it and the temps drop even more. Is that normal? Any suggestions?

[@MikePeperni]

When outside temperature are cold its normal, one thing you can do is make sure your temp gauge is accurate, if it is then you can use a sock that you cut and keep the ''leg'' part, you wrap the ngine's head with the sock use the lenght you need to keep it the temp you want. :)

[@alberteyde8024]

MikePeperni I’m in Florida, it’s been in the high 80’s here. Maybe the temp gauge is off. I know the temperature doesn’t matter a whole lot but I should at least be running at about 200 if the ambient temperature is 80, right?

[@alberteyde8024]

I was using bryons 20% with 16% lubricant. Maybe that is why????

[@MikePeperni]

@@alberteyde8024 Yeah it should hit 200, the gauge is probably off, the major issue with running it too cold is premature wear or failure of the conrod. They are tough but it can happen. :) If the engine feel decently tuned it probably is, dont try to overlean it, unless performance increase by leaning it. If not , and/or you hear the engine stutter after a wide open throttle pass, its too lean. What are you running the engine on?

[@MikePeperni]

@@alberteyde8024 It can be a slight part of it, but not much, id still use 30% at least if you want use more of the mod. I ran mine on 30%.

[@Ramipuchi]

the bench of picco 21 maxx is the same as the bench of 26 or 28?

By the bench you mean engine mount? theres picco .21 and .26 ''mid-block'' wich use a special mount, and theres big block mount for the revo that allow the use of Picco.28 Picco .21 big block and .26big block or any big block... :)

thank you very much :)

[@Ramipuchi]

How do I can prepare the suspension of the revo for asphalt? What I can do with roll bars or I can modify for use in asphalt? Recomendas me what wheels for use on asphalt? What make me recommend modifications for use in asphalt? sorry for my English

[@MikePeperni]

Rama Pucci For the suspension, i used a tie-wrap (zip-tie) around the rockers (grey suspension thingy) , just press on the truck you will see how they work, the zip-tie is used to keep the suspension compressed, make the a-arms level with the ground, not too low you have to keep some suspension travel... thats what i did, run stiff springs if you can it will be more stable... for the tires at that time the best option was the HPI Phaltline tires with tremor wheels (black wheels not chrome that will peels) , the tires can handle about 65-70 mph, what i did is use fishing line around the tires glue in CA glue that way they dont expand, but now some use new tires that were not available at that time, i dont remember the name but i think they are made by traxxas. :) goodluck!

thank you very much for your help, Greetings

[@wolfsburg91]

[@SilverStackers]

i havent forgot about this. lol its been on the back burner for a couple of years. soon, i will try slayer internal gears with a longer run way. i might bring you out of retirement again. lol

[@MikePeperni]

I remember you :), been a while though, goodluck for your next attempt, the target to beat is 75mph. I think we could have done 77mph with a little wing on rear, it was too unstable (light) on rear with the body on. The 75mph run was done with the body on to be a ''legit'' speed. I still have the revo, with exact same setup, havent been run since the 75mph run :)

[@SilverStackers]

yeah, the whole r/c hobbie got side tracked, but i plan to come back full force soon. ill make 80mph my goal.

how do you get your engines to run so perfectly?

you have to play with the 3rd adjustment neele on the carb, you have the high speed, low speed needle and then the medium wich is the biggest, be careful though it is tricky to adjust if you are not experienced with tuning. :)
