i would say about 280 hp and about 235-240 tq since i didn't see that you got after market fuel injector and still running oem and stock ecu as swell.oh and also i don't see that your running a front mount intercooler and if your running a side mount one that would also restrict some of your hp that you can get. but you never know you might be running more.

250-260WHP. Your stock injectors only get you to 250-260 and same with your MAF.

Youre leaning out really bad in the top end. You need bigger injectors and some control.

Please turn down the boost before you blow your headgasket or burn through a piston.

Im daily driving 11psi right now. i've only done 18 once and was wondering what i was producing.

Im planning on -Greddy Intake Manifold-HKS or SARD fuel rail-555cc or 550cc injectors-Tomei 70mm(i dunno if this is correct) or Q45 throttle body-Electric Fan-Lightweight 1 piece almunium drive shaft-Lightweight flywheel

Then of course tuning it. then ill work on suspension more. im trying to make it a all around car. Daily driver, drag, autox, drift, cirucit, time attack etc.

What MAF should i go up to?

BTW, SRs can make torque. My friends S14 SR w/ S15 Injectors and Z32 MAF with AFC NEO made 284WHP and 294WTQ.

Z32 should be sufficient....assuming youre not going crazy.

Please get the Injectors and Tuning together.

proper tuning can make you have more TQ than HP.

I agree with the consensus... You aren't making much power without a tuned ECU, let alone safe power. As stated, stock injectors and MAF max out around 270-280ish if you're lucky. Get bigger injectors, a Z32 Maf and a tune and you'd see safe numbers around 300whp.

wait. i run 14psi every once in a while on my t25 shouldnt that give me 300 at the fly wheel. theoreticaly. because i a sqezing two atmospheres of pressure in, shouldnt that double the power of the motor. so say with no turb othe motor has 150 hp. then double the atmospheric pressuer and you double the horse power.

^It doesn't work that way.

To the opening poster, You could be making less than 200hp without tuning. I had a similar setup to you and before tuning (and at 7psi) I was only putting down like 170hp at the wheels. After tuning I maxed out the stock MAFS at about 255whp and had the s15 turbo at only 10psi. I learned from that experience that your parts list means absolutely nothing without a good tune. Theres a good chance someone with a completely stock s14 sr is putting down more power than you.
