485hp 24psi?

[Poodles]

I don't think it's the head...more the cams at that point.

Need a full mod list to really know though...

manny those are some pretty good numbers.. i say just do some head work and u in there.. i dunno if i told you.. bbut i spun a bearing on my supra and i think im just going to go 1J and call it a day for next summer.. but i still want that Emanage if u got it

sorry i sold it. but as far as my list of mods:
7mgte
hks mhg
arp's
gt35r
custom header
24*12*4 intercooler
custom intercooler piping
aem ems
hks dli
rc 720cc
walbro pump
custom 4in downpipe
4in downpipe back exhaust
act clutch
thats of the top of my head for now

You're not far away from maxing out your fuel pump now. I've read where they were good for around five hundred horsepower. I made 543rwhp on one walbro 255, but that was only for a couple of pulls. Good luck.

 

[10secdream]

I would start thinking about an inline fuel pump at this point too.

 

[Poodles]

Yep, that and the cams will definately be holding you back now.

Really nice for stock internals though! Sounds like a damn fun car.

J made roughly 550 the Jz's have bigger valves I made 550 but as I said I have bigger valves as well it's just physics.

To make xxx rwhp you need to flow XXfuel/Air and light it off it's NOT rocket science

Something in the stock 7M bottle necks it, I said valves/ports as that's what my combination has but it may be just one or the other.

Of course this is just a generalisation as there as MANY other variables that come into play.

 

[Poodles]

Exactly, but more lift = more flow unless you're maxing out the ports.

Still, that's some damn good numbers for the mods...

would a set of 264 help? but with out taking away the bottom end. Also I would like to see when it spools up or what the tq band is like under 5k rpm.

 

[Zazzn]

you check for any boot leaks?

Or did you just jack the boost go out and dyno?

First thing to do

 

[tekdeus]

Those are great numbers for a stock 7M! I'm hoping to be in that ballpark with a GT35r.

 

[bmoss85]

im pretty sure people have made over 500rwhp on a stock 7m head. iirc, duane made over 600rwhp on the stock head, but he did have list of other mods.

Yes but more boost or a bigger turbo or both, the specific question was a gt35r @ 24psi on a stock head.

 

[suprahero]

I'm not sure Duane's car was ever stock or had any stock parts on it. I think it came from the Supra Mother already modded up. I could be wrong though.

Once upon a time, Iv heard him talk about 18-20 psi on stock 440s, who knew that wouldnt last long:sarcasm:Now I think the only thing Duane finds more fun than building such a beast is finding a way to make enough power to break it:icon_bigg

thats def not a normal car lol

 

[figgie]

Duane was one of the first folks to be running the TD06-20g from Greddy. He was also one of the very few to push that turbo to 500+ rwhp.

 

[Poodles]

Think he was the ONLY one to do it since he had damn near every other upgrade to the point that the turbo was the only thing holding him back...
