TRD Supercharger, NST 9.5 pulley, AEM F/IC with Tune from Church's, Forge 007 BPV, Tanabe Conept Exhaust. Anyone have any idea on some decent numbers with those mods? I was thinking around the 230's. My goal is to stop at 250 WHP or somewhere near that

All input is appreciated! thank you much

Probably 240

SMACKyoSELF

That's good enough! Haha. Thanks

but your in california, so you might get caught with modified exhaust, and the aem f/ic says "not legal for road cars in california"

but ofcourse, you can use those without too much fear or getting caught if you keep your car quiet, and your exhaust isn't blatently tastless.

LOL, well yeah that's true. I did get pulled over by the CHP and they just wanted to check my engine, saw TRD SC and all, and exhaust and was like, okay you can go. That was the WORST case that ive ever gotten pulled over for lol. So hopefully it shouldn't come to that case :O

Mr_Meaty

What was the cause of them pulling you over in the first place?

SMACKyoSELF

Because I was coming on the freeway from a ramp going 75 lol. Speed limit was 70, no ticket or anything, just suspicious i guess.

Mr_Meaty

oh, but you weren't pulled over for being to loud?

SMACKyoSELF

Nah, I have the Tanabe Concept exhaust.

i'm gonna estimate around 220whp...i had a similar setup with a custom CAI also and i pulled 220whp. Header and bigger pulleys or water meth will get you higher. Church's FTW though!

SMACKyoSELF

220? That almost seems low, but at the same time i'm not too used to FI. The 9.5 pulley is supposed to add around 23 whp? I think ZPI's added like 17 or something like that. And the tune? Not trying to question anyones judgement. I just don't know and would like to be informed lol.

BuddhasTC

compared to the stock pulley, the 9.5 lb pulley should only add around 10-15whp...its only 2 lbs more of boost. Stock s/c with exhaust has been netting around 200whp on a M/T so that's about right. You can hit higher numbers, but at the risk of running lean.

i think with the water/meth, header and a good mid-pipe you could be up to about 230-240hp with a tune. Maybe an intake for ***** and giggles, but it's up to you. But if you are gonna do this, get a wideband to make sure your AFR's are good.

draxcaliber

you say it is only 2 more psi of boost, but becaue it is a centrifugal style supercharger, the power made by boost goes up exponentially instead of linearly.

basically, if you double the psi, you don't double the hp, you quadruple the hp.

so it takes 7 psi to make the 50 whp with a stock supercharger, but then the next 2 psi from the 9.5 psi pulley adds 21 whp.

BuddhasTC

since it's centrifugal...it IS a linear powerband. upping the boost with a turbo will increase exponentially as the boost is not linear...i think you got it a bit backwards. Also, think this way...with 7 psi = 50whp then it averages 7.14whp for every pound of boost. So if you add 2 1/2 more psi...that is if you actually get the full amount of boost (i didn't), then you're lookin at 17.5whp increase. Since the pulley is what increases boost, and essentially only lightens the load to the supercharger when running, allowing it to run faster, then it will be linear
