Modifying the LRP 32X 4.1 & First Run

18% nitro fuel, reds 2104 Pipe, 14T bell

[@haywirerc]

Nice work. I've wanted to learn engine modifying. It's cool to make an engine and modify it for your own use.

[@TastyBRC]

Absolutely! Its simple... easy to learn, very fun and rewarding, it works 😁

[@ColeBriden-pl3fr]

​@@TastyBRCneed your help with this!

[@a2rc]

She got a little hot there at the end but, see to running and returning to idle pretty well. - As you know, it’s super frustrating to have a low quality/poor performing carb. I bet just changing the carb to the Rossi, helped the engine considerably Going over the timing numbers like you and Kings do, is a great thing. Even if you can’t “feel” or see a difference when the engine is running, you know you have modified the engine have can compare the before and after numbers. Nice work Thanks for the fun vid Tasty 🩷

[@TastyBRC]

The lrp runs good but I think I will open the crank a bit more. The temp was ok.. for an lrp. Usually she runs in the 140-45°C, she is more consistent and running a bit cooler after the mods. Sucking more fuel helps! Thanks for watching

[@mazpr2025]

​@@TastyBRCI would add just half an ounce to an ounce of castor oil to a gallon of nitro fuel. I do this to all my fuel, it does make a little bit of mess from the exhaust, but the engines run cooler. Usually, imo, porting the sleeve, In port the intake and boost ports, but rarely the exhaust. It is a .32, is a torque monster, put a good .21 engine and imo will run much faster. I would change the clutch bell a teeth or two bigger for more top end, and remove some of that nasty low end torque. The buggy sounds good, but I think you are limited by the fact it is a .32. I would like to see it rippin in the dirt, most throw some nasty roosters ...

Nice . Blue power. LRP yes sir. Love the channel. Keep up the great content😊👍always.🔥💯

[@TastyBRC]

Thank you Crazy Dad, this is my most powerful engine for sure, blue power 💪

[@RCWright]

Very nice indeed! The idle on that is awesome drops really nice. Seems to have plenty of power, I bet it goes through the fuel quick haha thanks for another great video 😊

[@TastyBRC]

Yes she's very thirsty 😆 Thanks for the comment Robert.

[@Nitro_rc_life]

Very nice as always

[@TastyBRC]

Thank you Bret

[@mcnitro874]

awesome mate awesome. definitely seems like is gained some power I would definitely open that window so you can lean her some more ❤

[@TastyBRC]

Thank you, different pipe, opening the crankshaft a bit more, ceramic bearings.. still need to mess with this lrp

[@g.b-MTB-trail-jumps3062]

great clean job champ 🤩🤘

[@TastyBRC]

Thanks for stopping by, as always!

[@NicholsonNitroWorks]

Its making good power on 18%. Plus your in tall grass. Run 25%-30% and a dirt road its going to be vicious . 4 more degrees blow down 9mm carb venturi. My mugen truggy pulls wheelies with 30% 14/46 and 155mm tires. similar mods to the same engine.

[@TastyBRC]

Next time I will try with a different pipe! The reds 2104 is a top end pipe but she still make good bottom power. Thanks for stopping by ✌️

[@NicholsonNitroWorks]

@@TastyBRC yes I use a novarossi 9886 pipe and it’s very strong in the mid range . I tried the ecrm side bleed and it had more top end with less midrange.

[@MaxwellBuckner]

Sick mods! runs nice!

[@TastyBRC]

Thanks ✌️

[@kings-racing]

Great vid buddy 👍 By the sound and temperature you can open the crank some more. You can't really compare the crank timing with a .21 since the displacement is much bigger. Think the exhaust timing and blowdown is good. I wouldn't take more material of the counterweight if you want topend. It now spools up pretty quick. Wonder how far you can open the crank before it's getting to weak....maybe 240 max???? Try 230/235 first i guess.

[@TastyBRC]

Thank you Kings. I was very surprised, Rex got lower numbers on the lrp 32 but I am very accurate on these numbers, maybe higher numbers on the 4.1. I will try a different pipe before modding again. The reds 2104 is a high end pipe but the torque was crazy with this pipe!

[@josephsaucedo8691]

Sounds like a screamer 💯👍✌️😉

[@TastyBRC]

It does 😄 Thanks for the comment

[@davelowets]

I run 30% Nitro in my 32x Spec4, and it runs cool as a cucumber, and holds a tune really well. I hardly ever have to touch the HSN, and NEVER have to touch the LSN. I just run it, and enjoy it. No frustration whatever with this engine.

[@TastyBRC]

Stock carb?

[@davelowets]

No. It is an SH carb with the replaceable venturis. I've had great luck with this carburetor on various engines, and had heard that the LRP carburetor is not great, so I broke the engine in with the xtec carb, and then switched to the SH carb when it was time to tune.

[@s.o.sSavage]

I found the stock carb and the spec 4.1 good I have a nova Rossi carb on the zr .28 though I believe you did a separate video on what carbs fit👍

[@TastyBRC]

Hello! at the beginning I also found the original carb decent but it started to fail quickly, a nova, os or argus carb is a major upgrade

[@s.o.sSavage]

@@TastyBRC I have a nova on my zr 28 and yes it’s definitely a totally different experience. But so far the newly designed lrp carb on the .32 spec 4.1 is doing ok obviously you know they thermal lined it as the old carbs go to hot and boiled the nitro! I hope it hold up for a wile because nova carbs are hard to find and my os carb is on the Mach 28 which also has a terrible stock carb 😂

[@GrandPitoVic]

It runs nice. At a point you get diminishing returns. I wouldn't go any further.

[@TastyBRC]

Agreed! Next I will try with a different pipe 💥💥

[@GrandPitoVic]

@@TastyBRC That will def change the power band

Hello my friend 😉 👌👍

[@rcsendandblast1579]

Wow

[@forzabike]

Is there an equivalant carb that is still manufactrured today? For example a reds or the new nova brand carbs? As novarrosi is no longer around. Thanks

[@TastyBRC]

If novarossi carbs were so populare its because they were pretty cheap, OS carbs are better and Argus aswell IMO. Check this video ✌️ kzbin.info/www/bejne/eIvPo4CCi7abi6csi=w72unz7-rac9F_DP

[@forzabike]

@@TastyBRC Thanks for the reply I appreciate it!

[@nitro-rc6241]

@@forzabikeif I may chip in, the Hobao Mac 28 carb is a straight drop in replacement. I have some shorts on my channel with it, “mugen with an lrp” is with the Hobao carb.

[@kawicepticon8866]

good work brother , those timing numbers need a shorter manifold. If you put on a 41032 or GT mani with on road pipe it will be eye opening 100%.

[@TastyBRC]

Thank you! Onraod pipe.. why not!? I would like to try it again in the gt but those plastic gt gears are super expensive 😅

[@Rc_Revo-Nitro_Andalucia]

Salut Tasty, j'ai quelques questions pour toi qui, je pense, pourront dissiper mes doutes. J'ai un LRP zr 28 spec 4 et j'utilise 16% de nitro. Pourquoi ne puis-je pas garder le moteur au ralenti avec un écart de 0,5 mm ? Même lors du réglage de l'aiguille de basse, elle s'arrête. Je ne sais pas si je me suis bien expliqué, je veux dire que pour maintenir un ralenti correct ni riche ni pauvre, je dois avoir un entrefer plus grand que d'habitude. Pensez-vous que je dois modifier la hauteur de la chambre de combustion ? Bien entendu toutes les conduites d'essence, le réservoir, le carburateur sont tous en parfait état. Le moteur tourne très bien et crie très bien. Mais il ne tient pas parfaitement le ralenti comme il le faisait avec ma Dynamite Big Red.

[@TastyBRC]

Salut, j'ai aussi un LRP 28 et avec le carburateur d origine, il est impossible d avoir un ralenti parfait. Pour que le moteur ne coupe pas, il faut qu'il soit haut. Le carburateur d'origine rend le moteur instable. Regarde cette vidéo✌️ kzbin.info/www/bejne/eIvPo4CCi7abi6csi=-hO8jvpJnn8JwwTm

[@garagegamer6484]

How I wish my LRP idled that good. I still have the stock garbage carburetor on it. I also have problems reaching the idle screw with the muffler in the way. I want to swap carbs just not sure what to put in it.

[@aimlockersesp7680]

if you can find used RB engines that have the original carb buy it drimm it and put it on the carbs on RB engines are exact same as the novarossi

[@TastyBRC]

Wont run perfect with a nova carb but much better than the original carb.. wich is pure crap

[@aimlockersesp7680]

@@TastyBRC i buyed for total 90 € 2x OS 21 j carbs

@@aimlockersesp7680 good deal!

[@ColeBriden-pl3fr]

[@TastyBRC]

You will be lucky if you find a nova carb. Check this video ✌️ kzbin.info/www/bejne/eIvPo4CCi7abi6csi=Ln0aOwDF7l7bElvF

[@CtrlAltFumble]

Can you measure the .32 and .30 outside sleeve size? Seems they're pretty much same size, I'm wondering if I can swap them.

[@TastyBRC]

I can measure the .32 for you but I dont have a .30, sadly. I heard the .30 is the best lrp

[@CtrlAltFumble]

@TastyBRC thanks, yeah the .30 is badass. It took 8 tanks to break in, lots of pinch! I have it in my on-road savage XL and it rips 💥

[@davelowets]

I like SH engines for just general bashing around. They have some power and last for a LONG time. I modded a couple up, and they wrre surprisingly strong. I think I had something crazy like 10+ gallons on the modded RTR SH B-01 .21 in my GS Storm, and i BEAT the SHIT outta that thing.

[@TastyBRC]

I had a couple SH 28 3p and they lasted very long. As you said good engines for bashing around

[@davelowets]

​@@TastyBRCMe too. I had a few SH .28s 3p and they lasted a long time. Then I came across a new Dynamite Big Red .28 6p for a good deal, and then I found a .28 pro 8p piston and sleeve set on clearance for $20, so I bought a few sets and threw one in the Big Red engine. It's been a strong runner, and I still have it. I like the giant cooling head on the Big Red, and it is GREAT for extended bashing sessions. Stays cool all day on 30%. 👍

[@fredtotton7903]

What novarossi carb do I use on the 32 lrp 4.0

[@TastyBRC]

Any novarossi carb from a .21 to .28 nova engine will fit kzbin.info/www/bejne/eIvPo4CCi7abi6csi=hXzWgxshrhKhT8dX ✌️

[@davelowets]

Not much exhaust smoke in the upper revs..... 🤷🏻

[@TastyBRC]

🤔

[@davelowets]

​@@TastyBRCWhat percentage of oil is in your fuel?

[@aimlockersesp7680]

You can tell me what ever you want but this LRP 32 engines are very good for the price if you have a 400€ engine compared to this and you pay the half price of it. For me im just saying for me i go for the lrp z32 first . You can run a .21 engine on a buggy but you can run a LRP z 32 on everything for me

[@TastyBRC]

Right the lrp will Pull any car, needs a bit more patience but runs strong. Also they are surprisingly durable.

[@Nitro_rc_life]

Still nothing like the os power

[@TastyBRC]

Agreed!

[@anthonybologna188]

Do you modify nitro engines for anyone. I want a strong nitro engine for a old 5.9 SavageXL Monster Truck that will idle good at long term temps. My LRP ZR32 spec.2 never stays running , but I want the same torque & power. Or do you recommend a different engine for the HPI Savage XL or a carburetor for a new ZR32 spec4 that will run nice without shutting off every 30 seconds))? That's the only thing I can't stand about this engine. I'm sure Spec 4 isn't any different without you modifying it. Any info would be great, or if you want to sale one after you make it right anything). Thank You

[@TastyBRC]

Modifiyng your LRP wont help solving tuning issues.. you need a good carb: OS, Argus, Alpha, check this video kzbin.info/www/bejne/eIvPo4CCi7abi6csi=2NoDq4AzJATcfgIp Very very few choices of pullstart engines these days. There is the hobao 30 wich looks nice but I havent tried it yet. The Nitro Nation made a couple of videos of the Hobao 30, check them out.
