I know theres been posts about this before but im tired of lookin thru all the crap and not getting a good answer, so im posting this to see if any of u guys (2.4 or not) have seen a big difference after using Meth.
Beside it being a good cooling mod, what kinda power could i gain from it after...?
has anyone seen a difference in the dyno numbers maybe!?! If so what kit are u using

 

0, in fact you'd probably lose HP if you slapped a meth kit on a N/A motor. If you aren't running a forced induction setup there is no reason to run meth


on my Caliber SRT-4, running 50/50 meth allowed me to add 2psi and 2 degrees of timing, which netted 23whp - there is no direct HP gain from running meth, it just allows you to run more boost and timing due to cooler IATs and mimicking higher octane fuel

 

he is supercharged

 

no im boosted.. i was just saying as far as maybe down sizing pulley or doin timing changes, in the end how much hp did u gain from it

 

fair enough - I wasn't sure given that it was posted in the LE5 section


for SC applications certainly the biggest benefit is going to be the cooling aspect, HP gains would be minimal. 10-15 if you can get away with 2 degrees more timing and another pound of boost

 

i have been able to crank out like 8* more of timing advance on SC set-ups using a 80% meth 20% water mix

 

Yea. I say you could gain some real power using a nice meth setup.

-it was in my post you quoted

 

Yeah braulio was tellinme thts wht he ran. We should be dropping tht setup in mine hopefully this weekend

 

I'll let ya know in a couple of weeks when I get mine installed. I got the alcohol injection system kit, only thing is I cant tell what kind of nozzle(gph) it came with.

 

How much timing were you running before and after? 8 degrees is a **** ton

 

17* of timing advance with no meth

25* of timing advance with meth on a 7gph nozzle

 

eesh 25 degrees on pump gas + meth?

 

yep

 

im running a 2.7 with a 7gph nozzle, and can only get about 20 with no knock. You guys must not have very dense air, or are a higher altitude

 

tvs's on 3 inch pulleys making 21psi at sea level

 

gotcha so his iat's were alot cooler than mine

 

not that low. its rarely under 90* out here. IAT2 are normally 130 at cruising. at wot they can go up to 150-160

 

hmm thats weird thats about the same conditions here right now. im also only running a 50/50 mix, but i didnt notice a really sufficient amont of cooling on the iats so im may go up to a 80/20 mix to run more timing

 

i'm running 2.6, 7gpm nozzle, H/E, dual pass, LS4, 3" intake, option B, and i'm running 23* of timing advance no knock no problems
meth mix is 50/50-60/40

 

i have gm dual pass w opt B ZZP stage 3 he and a 7gph nozzle. Id like to see some logs from your tune

 

cooling from the meth kits are negligible IMO. it helps but barely. just up the meth content and throw some more timing at it

 

thats what i plan on doing. Now grant you alot of time was spent in tuning the VE table on the car which alot of people dont do, so when we got to tuning the MAF the car was major heat soaked that didnt help matters

 

contact BYT he's the **** we could have put more timing he said but i said no still driving the car everyday right now

 

what were your iats looking like at wot?
