Oni Snake · **HP gains?**

I'll have my car set-up to top at 15psi, what kind of HP should I be looking at on an otherwise stock car? I'm getting on average 11-12. I may go to 17 as I've heard it is quite safe for the stock engine, and cooling system, to run at those boost levels.

its about 5-10 extra hp per 1 psi...so at 17 ur looking at 20-40 hp gain, depending on supporting mods such as exhause and fuel....at 17, if you have no boost leaks and everything is running perfect u maybe at 270ish with about 300-320 tq, again thats perfect everything.....

oooo, that makes me horny a little bit...270 at the wheels...hehe...what...you have an STi??

Would it make sense to buy Stage 1 with this mod? Could I run higher boost than 17 with it?

lil4drturbo · 12-03-2005, 03:46 PM

nope...17 is max for our stock map sensors...now S2 and S3 u can run more, im not for sure how much, but u can....now if you get a map clamp u can run as much as you want, but u have to make sure that you watch you aft....

ok, so 17 on a stock car is just fine for everyday use. That's all I need to know. That should keep me happy till I can afford stage 3

With 17psi I'm looking at damn near what he's after.. 250-270 depending on boost. Right? Or am I wrong in my assumptions of power?

For less than $300. Should I be worried about something? Should I regap the sparkplugs. Do I need a larger IC, etc. What else do I need to do to run safely? Or is 17 psi completly safe by itself?

I'm not looking for much, just a little more fun out of the car cheaply and safely.

I plan on getting a DP with a dumpout, will I run into problems with the boost being 17 and switching over to the dumpout?

Okay here. I have a S2 WGA (from the Mopar kit.. but I have JUST the WGA) and a DP with a cutout (like the one you want.)

I made 261whp and 283wtq on the dyno this past spring, without resetting the computer. After resetting the computer, my horsepower numbers were about the same but I put down 303wtq! I've got massive boost spike but aside from that, I was happy with the first numbers!

The only thing I'm not happy is the inconsistency. The stock computer will pull my boost down to 15psi after a few WOT pulls after resetting the computer. I think it's just a matter of making sure that the WGA is set correctly in order to smooth out my boost spike/PTB issues.

But again, you can't argue a 30whp and 20wtq gain from roughly $350.

((What's with the forum not letting you edit after 5 minutes?))

Anyway. You're safe. No, you don't need a bigger IC. No, I don't think you need to regap your sparkplugs. As for going with S1, I'm not sure. I thought I read somewhere that if you go with S1, it will pull more boost than S0. I'm not completely sure though; I'd have to do a little bit more research.

Plus, if you're in unsafe territory -- the computer will pull boost and dump fuel until you ARE in safe territory.

After adding the WGA I was scared that the higher boost levels would cause me to run too lean. But my AFR was off-the-charts rich for a majority of the pull -- so yeah, I'd say you're safe.

300 ponies right there....btw, as long as the ecu is in the loop for controlling stuff...you should never have any problems.....the ecu will pull timing and boost and dump fuel if needed to keep her safe....now when up put a mapclamp on, u pull most of the ecu out so it cant, but it will still try....our cars are set up to keep from destroying itself and to run the best...

nice, thanks you two.

This is my first "my" car, and first car I'll be adding power to. So I'm slightly nervous about flucking things up.

I've got the solenoid..now I need the voltage switch and the boost controller..woohoo

Mine too!

dont be too nervous, but if u are going tooo crazy, as questions first...like i said before, our cars will shut everything down or do what it can to keep from screwing itself...and dont worry bout breaking stuff, there is many people running over 400 ponies in these cars and have not broke anything, so by that you know that 300 ponies will not do anything, ohh and the S3 is at 350ish +....mopar/dodge/pvo built an awsome car....

Oni Snake · 12-07-2005, 08:10 AM

I realize that, I suppose I'll hit the "wall" on the stock turbo, cooling system, and fuel delivery before I actually break something.

lil4drturbo · 12-07-2005, 03:51 PM

stock is a bit higher then what u can do without some stuff, stock is about 20-22 psi, as in that write-up that i posted, the main part is to fool the ecu due to we dont have a 3 bar system, only a 2 bar, and need to up the fuel pressure.....stock injectors run rich, even on a S2 kit.....there is sooo much you can improve and not change out stock parts....
