Well im finally going bigger. Im going with a turbonetics t-76 and a 44mm wastegate. TurboTPI will be going single digits! Moral of the story, I will be selling my current turbo and wastegate if anyone is interested. 10,000 miles, 62-1, 1.0 a/r exhaust housing,watercooled center section. Wastegate is a 38mm tial. Both are in great cosmetic and mechanical shape. $700 for both.

 

hows the spool up on that turbo ?

 

It spooled very fast on my car. I have a 3,000 stall converter in my car. It was a killer combo. Basically no lag.

 

TurboedTPI, I've been curious about your car for a while. I have an almost identical setup in many ways and my car has always seemed crippled on the numbers. I recently found out my Megasquirt had a spark error of -9 degrees by 5000 rpm. After making some changes I have it under control but now the timing seems 'loose' and is never steady under the light.

Anyway I've only managed to put down just over 400 rwhp at about 14 psi. Car is running nearly 95 mph in the 1/8 which is decent but not where it should be. My cam is 224/224 on a 114 with a bit more lift than your ZZ9 cam (assuming you still have that in).

So my converter is a 2800 vigilante but it seems to flash too high. I was wondering if you see a similar rpm on the dyno and down the track. Our engines produce peak torque in the 3200-3400 rpm range and I can't seem to get below 4000 rpm as the starting point on the dyno. Down the track datalogs keep the engine in the 4200-5400 range. I think my torque is so high at 3000 that it is pushing the converter well over its rated 2800 stall. In fact my peak torque has also measured at barely over 400 at the rear wheels. This engine should be making over 600 at the crank easily.. probably closer to 600 at the wheels according to my friend's similar turbo tpi engine.

 

I agree, there is no reason your car shouldnt be at the same power level or higher. I do still have the zz9 cam in it also. Im curious why your car is not higher on power.
