Turn the boost down... You have 9.0 compresssion pistons along with a ?? thick MHG. And you have a stock ECU that is giving you overly agressive ignition timing. I would turn it down to at least 17psi if I were you.

Laaaaaaaaaaaaaaaag

I'm in Pasadena, MD. Check out the mideast section. There is a big meet coming up on May 15th near Chesapeake, VA.

Oh come on... You should be happy with your JDM MK4 NA-T converted to manual with 180K miles that you paid $25,000.00 for...

THere are other factors like the dyno conditions (temperature and humidity) and what gear you dynoed. A 3rd gear dyno run will almost always show a laggier graph. I do understand the .84 A/R will definately increase the lag, along with the 4mm bigger exducer wheel on the compressor side. But the...

That's a huge difference in spool. With that said, it looks pretty laggy(with the spool valve open) for an upgraded GT35R- Ive seen 67's come on earlier than that. Was this a 3rd gear pull on the dyno? For comparison, my regular GT35R with a .68 A/R would see 15psi at 3400rpm in 4th gear...

I would say about 370-380rwhp at 15psi.

Yeah, I thought the Pro EFI was not "available" for the 7M yet.

/\ I don't know about that. I used BFG DR's a couple winters ago.. There is no comparison between the traction of the DR and the street tire, even in the cold.

Easiest solution: Get R compound tires. I just ordered Nitto 555DR's for my car which have a nice compromise between straight line traction, cornering grip, and wear.

/\Didn't think of that..:)

I ran my 6 puck with a Fidanza flywheel and a stock flywheel and it chatters on both, but less with stock flywheel.

I'm still waiting for someone to actually cut open the muffler and resenator of the Tanabe exhaust and give us a true measurement of the inner diameter of the piping. Their is a slight narrowing, but to me, it did not look like it was 2.65". The exhaust is already 3.15 inches(80mm) and I would...

Thanks for the advise Mr IJ

Ok. My dumn question for 2010: Can I reuse my turbo inlet gasket? My original T4 gasket was only used about 50 miles before I took my turbo off and sent it back to PT. I'm ready to get the turbo back, and I'm not sure if I should use a new gasket.

Some Mustang dynos read much lower than dynojets. The Mustang dyno that I dynoed on consistantly read 14-16% lower than a dynojet. So you might be dynoing closer to 400rwhp on a dynojet. Still great 1/4 mile times. It was at about 480rwhp when I ran a 12.0 at 120mph.

/\ Good to know.. Thanks.

/\ Has anyone been able to get the timing control to work on the Maft-pro? And if the timing monitor is working, how much timing are you all seeing at full throttle?

I ran a stock internalled 7M at 400+rwhp for over 4 years. And that includes several track and dyno weekends where I pushed it near 500rwhp on race gas. Now I have a built 7M. Although the price of 2JZ swaps have come dowm a lot, to me it seemed more cost effective to build the 7M and keep...
