stock turbo

[laser001]

How much boost can I get out a a stock turbo with a manual boost controller.

One hundred billion psi!! Brwahahahahaha!!!

You can safely run 16-17psi if you have a good working fuel system and premium fuel. With a fuel pump you can get up to 18-19psi, but at that point you are limited by pump gas.

14b (I am assuming that you have a 5sp car) is a pretty good turbo, which many people overlook and get rid of it. I have gone [email protected] on one with 120k miles just to prove a point of how well it can do if given a chance. But I had just about EVERY other mod (minus NOS).

However, if you are into SCCA, something as simple as a MBC will knock you out of Sock or Stree Prepared classes and you will have to race in D-Mod or Streed Mod classes. So that is something to keep in mind.

I installed a manual boost gauge but didn't have too much luck with it. I ended up removing the mbc cause the engine kept cutting out once it hit full boost. It's kind of hard to tune without a manual boost gauge. All I was looking for was 15-16 lbs off the stock for the time being so thats great. Thanks for the info.

If you didn't have a boost gauge, how in the hell did you know how much boost you were getting?

Boost gauge first, then the manual boost controller.

Right, and I would say go to www.dsm.org, spend at least 5-6 hours reading and then do boost gauge and MBC

damn son, that's on the 14b? hm.... that's a good ass time, but damn if only the turbo was big enough to pull in some nicer trap speeds.

The 14b is pretty responsive. I run one right now to breake in my motor, and its quick as hell!

This has been a 14b record for a couple of years, but someone might have surpassed it by now. I did it on just one night out with the turbo, with almost no tuning and base timing set at 3 deg (by mistake). So with some morel tuning and better launching (this was 1.70 launch), I see no reason why 14b could not be taken well into 11’s (like 11.8 or so).

>damn son, that's on the 14b? hm....

Yes, and I had plenty of witeneses…

Nicer trap speeds? That is faster than most people get out of 16G turbos. And was also a 14b record.

well i'm just saying, on the other cars that run 12.0 the, traps are usually nicer..that's all, its ok, its still a nice time.

 

[AWDriver]

Phil Beers ran 12.2 with his ported 14B in his 91' AWD, pretty impressive.

Man, you got completely wrong way of looking at this! People who run 12.0 at 116-120 with AWD cars are not driving them to full potential. They actually have 11.5-11.6 sec cars. So it is not that they have "nicer" trap speeds, they run "crappier" ETs...

I know that since I got the big turbo and turned in a few of such bad runs, I am not very proud of it...

MPH dictates HP. ET's are an indication of hookup. All ET's tell you is wether or not you can bang a gear. Your MPH will tell you if you have a monster or a dud on your hands.

Nice job with that 14b et/mph!! I always new that it was a good little turbo. I had planned on keeping mine for a couple of years now, and maybe I will even keep it longer. Low 12's ?? Good enough for me.

 

[TurboSpoolinIns]

i am wondering, were these times on the 14b helped out with any kind of nitrous use?

 

[GRNDSM]

I have never ran N2O in my car...

 

[BigJohnGSX]

Ok, I just bought a 95 "stock" GSX, AWD. I plan on putting a DownPipe, Cat-back exhaust, Intake, and Blow-Off valve. With those mods alone, how fast should I expect in the 1/4 mile??? Also...the Hall*something* boost controller, whats the full name of it...where can I find a website with prices......and Those mods with that boost controller....how fast could I push that stock motor/fuel, in the 1/4 mile????

Thanks for any help

John
