Want 300whp but not by boosting the 14b to hell

[dsmsucks]

Hey guys I have the following mods
ported 14b
fmic
2 1/2 turboback
2g ported o2 housing and manifold
190 lph
kn filter
2100lb clutch
Now over the winter Im getting the following
gm maft set up
550cc injectors
logger
I know 300whp can be done with the 14b, but its done on race gas and boost over 21psi. I want to have this hp at lower boost like 16-18psi. Any Ideas, not to many more bolt ons I can get. Or Im just kidding myself?
thanks

injectors arn't rated on how much power they can support. They are rated in fuel flow. How much power they can suport depends on alot of other things.

The only way to make that much power at low boost is with a bigger turbo.

Although a Big turbo at lower boost or a smaller turbo at higher boost, if both are making 300hp then there both moving the same amount of air therefore you have the same amount of "stress" on the system...

^^
Agreed

Alot of my friends refer to me as a book of knowledge. I'm not a book, I'm a table of contents. I pride myself on being able to rapidly resource. I can find almost anything I want through the internet and books.



Not quite, you're decision to go with a 2.5" exhaust may have hindered your quest for 300 AWHP, but you won't fall short and it is entirely possible even with 2.5", it's just more likely with a 3".

So with that said and provided the car is in premium condition, turning up the boost will net you some numbers close to, if not exceeding, 300 AWHP.

U mean 300fwhp

I kind of figured I would need a bigger turbo (50trim) To get that hp at low boost!

Go 3 inches all the way, turbo 3 inches to the end of your bumper. Try going for a tune. I heard a stock sr20(I know!) got around 250 horses tuned?

Low boost doesn't necessarily mean you're "taking it easy" on the engine.

Example:

Which is going to put more stress on an engine?
A GT42R running 20 psi or a T25 running 25psi?

The T25 is running higher PSI, but is producing less airflow due to a smaller compressor. So, you need to consider much more than just 'PSI' numbers.


If you want 300 WHP on a 14B, you need to turn the boost up. The amount of airflow needed to support 300 WHP is not very damaging at all on your engine as long as you have the other supporting upgrades to go along with it. So, turn up the boost and make sure you have a good tune and enough fuel.

Look at my profile for mods, I haven't touched my fuel pump yet cause the bolts are soo rusty I'm scared to even look at them. I did rewire it though and I'm running 14psi on the 14b. Anyway I'd say I"m neck and neck with a STi if not a tad bit slower(I was catching up to him at the top of 3rd at G.A.).

I've been itching to turn the boost up to 16psi but I need some find some time and fix my phantom knock issue first.

keekeets, 25 psi on a t25 I wish. But anyway, nicely said!
