IMO, a the throttle body upgrade is one of the last things that needs to be upgraded when going for big power. A good turbo, exhaust, intercooler, fuel system, and engine managent should be the top prioreties. Upgraded throttle bodies fall in the same catagory as FF intake manifolds, upgraded...

Sounds like what everyone else is saying and what happened to me. My HPF bronze clutch welded its self to my aluminum flywheel. It also happened when I was doing a 2nd gear burnout (just like you).

I know its wrong, but I say M K 3. I also say third gen supra And I also call it oldshcool supra. As for the hatred toward MK4 owners, some of its well deserved. Of coarse 90% of it comes form the key board warriors on the internet. Most people are much cooler in person. But the truth is...

Great right up.. I have the HKS long runner manifold and my SP59GT (with the TO4E compressor housing) bolted right on with no fitment problems at all. I wish people would stop posting up pictures of that Greddy twin turbo manifold. Every time I see it, it gives me serious thoughts about...

A lot of MK4 guys use 264 cams. From the dyno charts I've seen, they can get you a good 50rwhp when used at high boost with a decent sized turbo. The nice thing about the 264's is that there is no real sacirifice in the power under the curve.

I make over 400rwhp on pump gas and over 500rwhp on race gas. Been running like this for about 2 years on stock internals. I would go with the eagle rods although someone mentioned them having standard rodbolts that are a little too small.

"also i'm having ahrd time launching on slicks. i'm bogging off line, at about 3500 rpms.." You will have to launch at a higher RPM with sticky tires. I launch at about 5000rpm with my 61mm turbo to avoid bogging. This is with BFG DR's. I try to do a fast clutch slip. Its gotton me 1.80 's...

12.4 at 119mph.

I'm running the HPF bronze clutch with the ACT pressure plate. It was running great until the disk welded itself to the flywheel during a second gear burnout. I'm going to try using the steel flywheel instead of the aluminum one this time. Maybe the the HPF disk doesn't work well with the...

I beleive DR J had many passes on his before it broke. I ran mine about 30 times at the track before my 3 to 2 shift at 90mph. It was just dissapointing to me that it would not hold any kind of launch after that mis-shift. I now have the horsepowerfreaks bronze clutch. But I have had problems...

Me and Dr Jones have both fried our Spec clutches. Mine was a stage 2 and his a stage 3. Mine ran great at the track with mid 400rwhp and hard launches. But one little split second mis-shift burned it up for good. The Spec held great on the street, but I'm not sure if its up to dragracing abuse.

I run the Lex, 550's, and FCD. I have run up to 25psi easily, and 29psi accidentally. With just the Lex and 550's, I would hit fuel cut at around 19psi. Whatever you decide to do, make sure you MONITOR YOUR AIR/FUEL RATIOS.

What are you talking about?/\

"I remember a few years back Mark Tozer dynoed 900 rwhp, or just above on a stock short block. The short block died at 31,000 miles he said. I don't think he put 31,000 on it with 900, but after that power was achieved, it succumbed shortly after." I think I remember that. It happened when...

Its too damn small. I can't put my dyno-analyzing skills to use.:evil2:

"will neely did those numbers with a sound performance kit. (sound performance exhaust manifold) the turbo was a t-66 like u said but not with a hks manifold" My fault. I thought he listed it as a HKS manifold. Either way, each will support well over 700rwhp. Hey Malloy, I thought you were...

Good luck, I hope you do it. It will be real interesting what you can squeeze out of that stock ex. manifold. Will Neely did 684rwhp with a T66/HKS manifold, stock cams but lots of head work including oversize valves. X-man di 637rwhp with a stock 7M with a HKS manifold and SP67 but with a FF...

Judging by your 1/4 mile trap speed, I bet you are closer to 400rwhp on a U.S dyno. 20psi on a T70 should be getting you at least 450-500rwhp. The 3mm headgasket is costing you power for sure. With race gas, you should be able to crank the boost up to 25psi on a healthy engine without any...

Odyssey light weight battery- Stock diehard battery: 40 pounds(yeah thats accurate). Odyssey battery 15 pounds. 25 pounds off of the front end. Hows that for balance?
