485hp 24psi?

[supra88gr]

i was just wondering my car made 485rwhp at 24psi on a gt35r set up using an aem ems? i thought it would make more at that kind of psi? any comments and how do i achieve this look http://7mpower.com/orian_iglesias.shtml how the intercooler looks in the front

Nope. Not on the stock 7m head you won't. The 7m head affect the turbo efficency zone by a significant amount and also affect the VE of the engine. Keep in mind that the more displacement the less intake manifold pressure needed to get to the same power.

What are you comparing the numbers against? A 2jz or even worse, a S54?

I made 550 at around the same boost here on my old 3540r
(non stock head)

 

[supra88gr]

my motor is stock except a mhg(7m) i just got the car back and that is what it says on the dyno graph. 24psi 485whp 478wtq maybe the boost gauge is installed wrong?

 

[IJ.]

No that sounds about right.

 

[empera]

stock head is that restrictive?

 

[IJ.]

65rwhp sounds about right for a port job and +1mm valves Emp.

 

[figgie]

stock head is that restrictive?

According to some rough numbers I crunched.

An emphatic fuck yes!

 

[IJ.]

Might want to qualify that with a "at stock output as designed it's pretty good"

 

[empera]

lol, i think igot the idea :runaway:

That's really not that bad of numbers.

I'm sure you're just frustrated to still see a 4 in front of your other 2 digits...
But as mentioned, That's about right.

Care to post your dyno sheet? How large is your turbine on that 35R?

I would have expected more also, but I didn't realize the stock 7m head was that restrictive.
Is the 1jz head just as restrictive stock vs. stock? My 1jz made 543rwhp @ 24psi, but the head had a mild port and polish, but it was on stock valves. I was later told by someone on here that a port and polish was useless with stock valves........apparently they were wrong. I cant' remember who told me though.

How well is it tuned? I know of a stock 7m that made 500 on 21-22 psi.

A MHG is your only engine mod? what does the rest of your "set-up" consist of? manifold, fuel, IC, etc...

I'm thinking tune too..

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

 

[grimreaper]

what fuel type as well

 

[Tun_x]

I'll cry if my car doesn't make more power than that at 24 lbs.

 

[suprahero]

Are you crying?

There's no crying in Supras.

You take your low horsepower and BHG's like a man damnittttt!!!!!!!!

This is turning into AA for boost junkies
