Ha...alright cool.

 

are u shitting me? stock pistons can hold way more than that.. its the boost that blows out our piston rings...
and the work was talking about the symantics of the supercharger...
but kk have fun yall.. i didnt come on this thread to get flamed...
ask cameron.. he knows all about blow'n pistons.
and i bet ur going to tell me my transmission cant hold it too huh?

i got 250whp. on a jet dyno with gmstg2 maping and other upgrades.... so dont tell me its possible. ur forgetting the 320CC METH KIT SHOT. u guys are used to the gm maping or the cobaltaddiction maping. go buy some hp tuners and **** with it...

 

No kidding

 

so if u went lower than a 2.9 u'd need bigger injectors and a tune right?

 

lower than a 2.9 yes
colder spark plugs lower the gap
i wouldnt suggest 60 injectors... i was told it over works ur fuel pump.. u wanna stay with the 55's

 

don't you need to do the boost bypast mod to reach max boost..or it will just bleed correct with a 2.9 pulley?????

 

Unless you get it tune correctly

 

Boost bypass is *BAD* *BAD* *BAD*!!! Never say those words again! All it takes is a little change with HPT to remove the boost limit. The boost bypass Quote Works Unquote by disabling an essentual safty feature of your supercharger. Don't do it. It doesn't even work about half the time for people are trying to get out of it.

 

I ran an intake, S2, and 2.85 on my 42's and ran just fine (with some HPTuners help)

No you don't need 60's, Area47 is running a 2.8 on 42s with meth.... so it's possible to run 2.8-" pullies without the need for larger injectors.

Get a "GOOD" tune and a meth kit and you'll be fine.

 

Keep the 42's and get it tuned. There is no need to go with larger injectors. I have a 2.79 with the 42's and a damn good tune.

 

Man talk about a subject beat to death....

 

And it will never end because alot of these peoples are new to the tuning scene and all and don't have reliable resources to explain why and how certain things will work.

 

I agree, but you dont even have to do a search on the subject here as every other thread is the same damn topic.

I'm still busting up laughing at some drunkerds comment he has 400 whp. The I saw he was from Texas...Lotta bullsh** in Texas....

 

LMAO!! Oh I know. It seems that every single newb asks the same damn questions and all the older peeps from this site have just gotten tired of telling them all to use the SEARCH button.

I would have to agree about the 400whp comments too. What kind of math are some of these peoples using? I need my local bank to learn that math.

 

I bet the dude thought when the dyno operator said he had 200 whp, he meant per drive wheel!

 

I also noticed that the stock tune bleeds boost, but with the GM stage 2 tune the boost appears not to bleed (minus TQ MGMT of course... but that can be disabled easy enough). I noticed this looking at the tunes in HPT. So if you have the GM stage 2 tune you do not need to do any kind of changes to get full boost as far as I can tell.

 

Bleeds boost?

 

Yeah, on the stock tune if you throw on a smaller pulley it will bleed the boost back to 12.5 psi. So essentially if you put a 3.1" pulley on a stock car you would still only get 12.5 psi, you would just hit 12.5 psi quicker in the lower RPMs. I think it bleeds at 12.5 at least, it might be 13 psi... either way you cannot got past that. Now with the stage 1 or 2 tune the supercharger does not look like it bleeds boost at all unless it detects high IAT2 temps or abuse.

 

Thats what I did ....^^^^^^

 

a cai intake will do more for the car than a stage kit to be honest because the car with the cai will gain power quicker and boost will come much faster than a stage 1 or 2 car. I would go as far as to say a cai would be the same as a stage2 with a 2.9

 

WHAT?! It's already been proven by several members at the dyno that an intake only makes a couple of whp.

 

Agreed lol

 

Is this a joke? Yeah, a CAI is like Nitrous for Boosted cars! LOL

Our stock intake is not very restricted, and already resides in the CAI spot. I agree with infinityzen i could barely feel the CAI on a stage 2, but a 2.9 was a lovely improvement.

 

ya im sorry, but you cannot be serious. you cant feel a couple of whp... sure there is a lil better throttle response but nothing drastic.

 

Hey guys, I guess a 2.90" pulley and DP F*CK up the clutch because now it's slipping. I guess it can't handle that extra 15hp?
