Because dragracing gets expensive fast, and the the majarity of MK3 owners don't spend lots of money on there cars. The more power you make, the more things start breaking. I'm on my 3rd clutch, blew a metal headgasket, broke both motor mounts, and recently I just broke a valve spring over...

Here you go:http://www.gnttype.org/techarea/turbo/intercooler.html

One good, simple formula for measuring your intercooler efficiency is by Subtracting your IAT's at full throttle by the air temperature outside. This is called the APPROACH. For example if it is 60 degrees outside and you IAT's are 90 degrees, your approach will =30. From what Ive read (I'm...

/\Nope. Just my memory from what I read.

"Link for the test? I'd be interested in seeing it " Wish I could remember exactly. I think it was on Honda-Tech. I beleive "Full-Race" did the test.

Get a Precision Intercooler and be done with it. The Ebays have been tested and they suck as far as bringing down IAT's.

I never understood why any one would want to put a smaller motor in there car, if making the most power is the goal. It seems like an import only thing. Whatever. I made 400+rwhp on my stock internalled(+MHG) 7M for 4 years with no issues. Now I have a built 7M that is making close to 500rwhp...

"The 2JZ is still easier. No head gasket worries (OEM is fine), No oiling worries (OEM is fine), no need for studs (OEM is fine). Fact is there are many 600-800whp 2jzs running un-opened OEM long blocks. The engine IS better. Heck just look at the number of BPU powered cars running 400-500 rwhp...

/\Agreed. Here we go again with these dreamers thinking that all you have to do is put on a big single turbo to get 1000rwhp out of a 2JZ.

Cool. But I bet that record won't hold up long to the viper. I love seeing how the viper and the MK4 supra are constantly breaking records in the 1/4 mile and 1 mile.

Its funny hearing these debates about weather a motor like the 7M can make 1000rwhp. Of course it can. The weakest links will need to be upgraded. But the basic design is there-strong iron block and a forged crank. And as for comparing the 2JZ; Saying that it's so much easier because of the...

"Nope, ask him." I did. Merry X-MAS.

What turbo? I thought it was a T78(66mm), but that seems to be trapping too high for a T78.

Still representing!

/\OK. Still going a lean at throttle tip-in. I'm probably heading down to the track next friday to see what I can do on pump gas. I still want head down your way some time. Maybe you can show me how to get this AEM right. I wouldn't mind checking out your supra too.

I also have the HPF bronse clutch except with the ACT pressure plate. So far it has been great at the drag strip at my power level.

Nice job Sean. And thanks for the videos. Obviously there is much more potential at the strip. I'm sure the car would do so much better in the full 1/4 mile. What kind of clutch are you using? I don't think your really going to see any real good times unless you get some very serious tires...

A stock internalled 7M with a metal headgasket will be fine at 450rwhp. I ran mine at low 400's for years and high 400's at the track. The questin isn't the 7M, it's the question of your particular 7M's condition and tune.

I wonder what part of the transmission broke. I thought the actual gears were very strong. Makes me wonder if theres something we can still do to make the R154 bullitproof.

Well, I made around 490rwhp on the dyno on my old setup with 550cc injectors (with the stock ECU) and the same pump before I started going lean.(Not sure if the airflow meter was maxing out). If the fuel pump is the problem, will the fuel pressure drop off under boost? Is that something to look...
