Estimated power on my stock 1j?

[djblastsupratuner]

OKay trying to figure out what my power output would be on my stock twins 1jz supra. i am guessing around 320 to the wheels??
Mods:
Weapon R intake
1 piece steel driveshaft
Y pipe and Downpipe 3 inch custom exhaust
440CC injectors
SAFC II
AVCR Boost controller 10-16 PSI
2.5 inch Intercooler piping and intercooler + ARC BOV

THanks anything to give me an idea helps!!

Only thing I see missing from the mods is a high rate fuel pump, and you should be at around 350hp at 16psi.
Do you have a FCD or is the safc allowing you to run at 16psi?

 

[djblastsupratuner]

oh yea i have a walbro fuel pump forgot to add. and i was thinking of getting a FCD but not sure if i want to run 16 psi lol

I dyno'd 320rwhp with stock everything but the exhaust, y-pipe, BC264 cams, and porting/polishing the head. This was at 12psi, high 10.x- low 11.x AFR's. On a stock head, 12psi, I figure you'd make 290-300whp. Between the intercooler and increased pressure, I figure you'd be in the 320whp range without much trouble.

After seeing my dyno numbers, I'm gonna agree. Somewhere between 330 and 360whp sounds right if she's properly tuned. And right around 280tq would be my guess if you're wondering.

What were your numbers, what mods and psi?

I need to go ahead and post a thread for it, but here are the numbers and mods

297.57whp 319.98tq
17.21psi
stock cams
Stock twins
Stock exhaust
SAFCII
AVCR
Driftmotion intercooler and hardpipe kit
Koyo Radiator
Southbend Stage 4 Clutch
And 440cc injectors that according to my safc and avcr, I could've done without.

^ Wait, a 1j that put out more torque than horsepower? Strange... Tanya, what was it you were saying would happen if you ever saw that???

Yep. Better cash in.
One thing we noticed about how people dyno a 1j is that generally they've already swapped the exhaust. Well that's a double edged sword. Yes, you're hp number jumps up due to increased flow, but since you eliminate back pressure, your torque number drops dramatically. Trust me, when she put out the numbers, we all but told the dude his dyno was broken.

 

[te72]

Heh, that's pretty funny about the dyno being 'broken'. I did notice you had the stock exhaust on there. Stock y-pipe is a bit of a restriction though, just like the CT26 elbow... You would have likely leveled out your hp/tq figures with at least that much.

I still wish the dyno at the last SILV would have had a torque readout, but they only gave us HP ratings. Might be dynoing my car up here soon though...

Yeah. I have a full 3 inch exhaust waiting, but I refuse to go below 300ft-lbs. Plus I don't wanna take my turbos off unless im upgrading them. So soon and very soon i'll be making bigger numbers all the way around.
