colorado loud valve on and off dyno testing

[@HISS2004]

Matt I think you missed your calling. Shoulda been a teacher. Learned a lot just from watching the channel about late model stuff, turbos, and tuning. Thanks for everything, from the little people.

[@SloppyMechanics]

people say this all the time, that i am great at explaining things

[@TheProchargedmopar]

Loud valve is like having a 100+ shot of N02 without ever having to fill a bottle. Sweet!!

[@madmax2069]

That loud valve is awesome, it allows you to be quiet, and when need be opens up and allows the snail to fully wake up. You sir are awesome.

[@richardharris492]

Wow, Awesome results! That's NO BS for sure!! Hard to believe but that's some great #s for this combo. Thank you Matt Happell !!!

[@scarface-39]

Unreal how much horsepower you can get out of that thing!!! amazing!!!good stuff.

[@SloppyMechanics]

+Scarface 39 it’s proving to be quite the combo

[@nffd23]

And i thought all youtube content was garbage. this is great! 10/10!

[@strkd47]

Not all hero's wear capes. That should be enough power to blow those street tires off all day.

[@Rebel635csi]

Found the same thing. Same boost controller duty cycle with exhaust hooked up gave me 14 psi and just the 3.5" down pipe resulted in 18psi.

[@EDWARDTREVEY]

Street Truck clam down STREET TRUCK ... Still laughing and I wanna hear the full version uncensored

[@franciscovasquez4555]

Great insight into a budget friendly set up keep up the great videos and testing

[@juiced71]

Wow great numbers! Fun truck!

[@8wireracing694]

Bloodyhell thats a big difference..friggin awsome. This setup personally my favourite so far i like it alot. Had me a sloppy epiphany..im messing with ls1 hsv holden but never had courage to jump in..i should be boosting one of two 3800 v6 holdens i have as they are a dime a dozen.

[@justin_parks]

That is pretty incredible. It seemed to spool faster with the valve open also which should be obvious i guess. But it was a good second difference maybe more

[@Mattg02]

Very cool I enjoy the hole series.

[@onlyychevys]

calm down street truck calm down lol

[@SloppyMechanics]

+onlychevys Williams too rammy

[@wobblysauce]

I think it is after some icecream.

[@evanjarvi406]

Love the Weezer in background had flashbacks of 8th grade👍

[@jeffyjoebob8300]

Evan Jarvi if u want 2 destroy my swetaahhh

[@TheBrokenLife]

Calm down, Street Truck! Calm down!!

[@ephil789]

Maxwelhse we need a t shirt that says this.

[@stevebauer6293]

You should go to the KZbin callout at Cecil at the end of October.

[@SloppyMechanics]

maybe ill think about it, not really my thing though haha

[@TexR6S]

At 11:19 I thought this must be Matt, "Why the fuck did I just close the door?" 11:39, the door opens. I'm way too obsessed with this guy. LOL

[@billantalek8806]

You boys like Meh He Co? Hahahahah Hilarious!

[@LaswellB]

Very interesting results. I just ordered a valve this weekend, and on my full exhaust, procharged setup, I'm wondering what gains I may see with the cutout open. I'll report back.

[@ramairgto72]

It's funny, most of the YT channels I belong to, the posters seem to know about the same YT channels. Sloppy, AVE, RodeKill, Guns & Gadgets, Cletus Macfarlane , superspeedersRob...

[@JSparrowist]

Good channels get watched. It's no surprise.

[@Bjoernlaehndorf]

I believe the big hp difference is caused by (as i recall 3") to small of an exhaust system - would be interested in seeing a 4" or even bigger tube dia.

[@Reesecup1200]

Thank you for the super troopers reference.

[@kevinhodgkinson3557]

Who is that one prolapsed a**hole who down voted this great content!

[@SloppyMechanics]

i have a fan that downvotes every single video lol nice to see he is still kicking

[@james10739]

Looks like you have 3 now

[@Turbogto_guy]

Kevin Hodgkinson there are some shitsticks in this world. Probably just some miserable sacks of shit.

[@lwclark]

Near Hellcat power on a junkyard 4.8 and chinesium turbo. Insane. Wonderful. Insane.

[@SloppyMechanics]

hellcats dyno 630 on my dyno, and they have locked transmissions, so technically more power than a hellcat

[@lwclark]

Sloppy Mechanics true! any idea what more the alcohol lets you get away with safely? Btw there's a $300 4.8 in my garage waiting for this semester of school to end :)

[@tptrsn]

Great video Matt, and thanks for explaining your reluctance to drop in the 210s because it gets you into the "shit spot." I get it now. Am I correct that the setup makes about the same power at the same boost with and without the loud valve, but when the loud valve is open it just makes more boost than with it closed? In which case, I guess I'd prefer quiet exhaust for streettruck.

[@SloppyMechanics]

+Hammerhaus Kennel yep it puts you into a money spiral ending in bent rods lol, correct it seems to make the same HP peak but spool up is faster.

[@tptrsn]

Sloppy Mechanics thanks!

[@oodakdak]

Whoah! Calm down st truck calm down! I Love it haha

[@JBAutomotive794]

That BOV and loud valve doing work!

[@jesscneal]

Welcome to Automotive Science class kids. Pay attention.

[@SloppyMechanics]

bust out your stinkpads and take notes

[@ladams00]

Fuck that 5 series! Hahah

[@WS6xMASTER]

Im wondering if the fact that the loud valve was causing more boost just because it was hooked up to +boost pressure. Idk just a though. Probably a dumb that but just food for thought. Little late now either way lol

[@lococubaa]

the denham, could you be seeing more psi due to the vacuum being applied to open the loud valve? I've seen turbo honda guys adding "T" fittings to the vacuum line before the w/g to increase boost.

[@TriniRogue]

As a budget minded build one couldn't ask for better results, after seeing those 600+HP's pop up I'm now thinking bout the limit of that engine loll ohhh how addictive power is xD

[@richardgreen1142]

I swore I seen this on your page, how would this set up do on pump gas? No changes, just less E and more gas...

[@SloppyMechanics]

its capable of the same power on pump, you might just be octane limited, depending on your gas quality, elevation etc

[@juliahobbick4604]

hey just thought of a great idea. Do you feel it would be worth it to place a loud valve in front of the turbo intake, that would filter the air under vacuum and under boost bypass the turbo. My only thought on that would be maybe the valve isn't air tight and would in turn bypass the filter anyway. Any thoughts?

[@james10739]

Did you ever take it to the track with dont BS me

[@Dabigcheez89]

Those are some fancy shop shoes

[@SloppyMechanics]

i call them osha approved flippys, or jesus cruisers

[@Dabigcheez89]

Ninja slippers for creeping up on the magic bent rod hp number

[@kyleorsak]

So at 72% ethenol with 17 degrees what would be a good timing to aim for if running 93 and a 50/50 water meth? I'm around 12lbs and 14 degrees timing now. Seem I can up my timing more just not sure what too

[@SloppyMechanics]

theyre all different, but a general rule of thumb is most combinations on pump, with factory compression i like to get them to see 14psi and 14deg peak ignition at peak rpm, then i move everything around from there and see if the car makes better power with 15-16deg over 5000 or so, and take some out of the mid range and see what i can get away with, read plugs, check the dyno etc.

[@HunterTuned]

you should try just pump and find the true limit of the injector

[@jeremysmith3556]

Do you still have traction control on this or is that not possible with the stock computer?

[@SloppyMechanics]

no it does not

[@bigj7807]

Are still able to turn it down on the controller to say 10-12lbs of boost or is the loud valve just pull you straight to 17lbs no matter what?

[@SloppyMechanics]

+John H I can turn it down to 3psi

[@TheProchargedmopar]

Pump, Injectors, converter.Let's Go! Bigger, Stronger, Faster.... You got this.Just Do it!Then drop the PORTED heads on it!!!!!

[@dridiott]

TheProchargedmopar he already done did dat. The whole point of this project is what can be done on the cheap

[@TheProchargedmopar]

Yeah, this project is over time to move on to the next episode. He has ported heads sitting on his bench. What is the use in testing them when his current setup will not support more HP. Lets GO!! Max out the billet 78/75 and Drop some heads on to see apples to apples without the lack of fuel. 4.8's are cheap before the sloppy tax kicks in so lets put it to the test!!

[@HunterTuned]

its probably past pump. My setup i can run 22 psi and be 10.0 pegged 7875 cast wheel with 2 bosch 044 pumps and ebay regulator set at 58 psi base

[@HunterTuned]

no clue on my duty cycle tho

[@jesusm2797]

What boost controller are you using and how do you plumb it? Just seen different configurations and not sure witch to go with.

[@SloppyMechanics]

its a super simple ball and spring inline

[@jesusm2797]

Sloppy Mechanics bottom port and vent one side or top port ?

[@dalevandermeer719]

Nice job

[@SloppyMechanics]

hey thanks!

[@Dimk3232]

Dale VanDerMeer щщщ

[@turboed00SI]

Which turbo is this Matt?

[@SloppyMechanics]

VS racing Billet 7875 currently

[@sharkcitywarrior5485]

Do you code out the knock sensors ?

[@SloppyMechanics]

+SHARK CITY WARRIOR they are still installed and in use

[@yayaya1193able]

matt would you sell the colorado?!?!?! if so how much??? thank you!

[@SloppyMechanics]

yes, 8k right meow

[@mjminino]

20k lol

[@Calvin-Nelson]

Is that on a single walbro 450?

[@SloppyMechanics]

+Nivlac57 correct

[@Calvin-Nelson]

Sloppy Mechanics Wow. That is extremely impressive. You should look into decapped flex fuel injectors.

[@SloppyMechanics]

there is plenty of "looking into" done already on the decap injector group dale follett started on facebook, they are slightly smaller when decapped than what i have now.

[@Calvin-Nelson]

Sloppy Mechanics I was unaware of that. Thanks for the knowledge!

[@garythorpe2387]

Sorry I ment under vacuum

[@combee23]

When you show 17 degrees of timing, do you run that across the board, at peak torque, peak hp, or redline?

[@ladams00]

combee23 my guess is peak torque, but I'm not Denmah 😉

[@hereinmissoula11]

probably up top....... less in midrange

[@SloppyMechanics]

17 means, 17deg at peak power, peak boost, at peak rpm, its always a ramp from lower timing at lower rpm to keep the gen3 alive, you dont wanna smack it with high boost and high ignition down low, usually

[@combee23]

Alright, that's what I do as well. When you run 17 deg at peak hp, what do run at peak tq? 10/11 ish?

[@hereinmissoula11]

every combo different..... go till you get knock ,take couple out, ramp it in up top till it does same. i usually start 8-10 , go from there

[@anthonysalinas9699]

You running a 4l80 trans?

[@timdav4548]

Got a new ring tone. That hit with out loud value...

[@LoneRevD]

♫ Steee ttt Truuuu ckkk ♫ Lol..

[@SloppyMechanics]

calm down, calm down

[@jtc18]

In your honest opinion, how much more then 640 do you think it's capable of, while staying reliable? A pump and injector might take you over the threshold.

[@SloppyMechanics]

man not much, i have learned to keep the power out of the mid range by keeping ignition out of it, and also with this slightly loose converter might help it, but yes i agree, asking more of it all the time might be asking for trouble, at this hp level its plenty for a street truck like this IMO and reliable.

[@jtc18]

I'm only just in the middle of my first ls turbo build now, I do have an TT, blow through 455 Buick in my rat rod and I have learned that reliable is way easier, running on the ragged edge is fun and makes great power but not when your putting pistons in it every couple hundred miles, especially when you grenade it 90 miles from home and have to wait for a trailer to rescue you. I like to drive my shit home, not tow it.

[@Noswolf]

im aaaa streeet truuuuck

[@dilsher12]

I forgot if you had the triple disk converter in this or not . Should try locking it and see how much difference does it make

[@dilsher12]

I got the answer its the budget converter

[@MrGuvEuroman]

Why don't you ever put like a cone filter on the turbo inlet? Are you not worried about stones or debris?

[@SloppyMechanics]

+MrGuvEuroman more often than not the filter itself becomes the “debris” that ruins the turbo

[@abelk918]

Haha you said dooty cycle

[@SloppyMechanics]

Doodie

[@dinxsy8069]

True sleeper.

[@benderisgreat1469]

Could I get a diagram of everything I would need to swap my 05 colorado please

[@SloppyMechanics]

yep, just search on google.

[@JoeHynes284]

but 4.8s are garbage...

[@SloppyMechanics]

hot garbage

[@Pipitarutor]

obviously shit. No potential

[@ZoDDyXXX]

Really? Over 1000 reliable hp´s and a well known junkyard performer pushing several cars down to the low 8.. garbage? It seem that we all have different references :)

[@MegamanEXEv2]

ZoDDyXXX sarcasm bro...

[@BumPudding]

Rip a big skid mate

[@SloppyMechanics]

yeah i absolutely need to

[@curtisthecarguy2974]

the ecm i need to send you for a turbo tune is still stock do i need to get the vats remove before i send it? or can i just pay you and make it a one stop shop . thanks

[@CommandoPG]

Ma boi's Vtecs will beat that there ford

[@anythinggarage9602]

Ford what ford

[@garythorpe2387]

Hey sloppy your blow off valve opens under boost

[@richardharris492]

Gary Thorpe it's not the blow- off , that's the loud valve opening to free up exhaust!!!

[@garythorpe2387]

Richard Harris watch the bov I ment to say it is open under vacuum

[@garythorpe2387]

Attention sloppy bov opening under boost

[@tptrsn]

No it isn't.

[@SandMan2SS]

No it's opening under vacuum and closing under boost

[@whatchu_talkin_john_willis]

that shiny thing you see is the piston. the boost on the top side of the valve slamming it closed
