I don't have any dyno charts with torque or RPM figures. The RPM pickup was not working on Jeremy's dyno, so the dyno chart with whp on the first page of this thread is all I have.
The overall torque has improved immensely with this new engine. It truly feels like a different car... Unfortunately I can't quantify it without a dyno sheet... sorry...

It's amazing what a set of new pistons and cams will do for performance... the 4.08 gears really like the extra 1000 revs, too... I have to admit that I ran it pretty hard on some of those back roads... fun day...
The Run is always a super fun event! How'd you like the new route through all the back roads?

I absolutely love the setup. It's clean and the car is very understated. What a beast. The power is really impressive, but not surprising seeing that your VQ can breath well above 7000rpms. I'd love to see another dyno with the HP and torque over rpm. If I had a good bit of money, I'd try the same thing with a 350Z. Those 4.08s are a wise choice because how much rpm your car has now. You could actually get away with 4.3X gears.
My question to you is why not the Cosworth intake manifold. It doesn't do squat for a standard DE/Revup, but with your car's breathing ability, it would be a perfect match and you'd probably see a bit more power.
I LOVE THE FACT THAT YOU KEPT THE STOCK INTAKE!!!!!!!!!!!!!!! That is the best evidence I've ever seen showing that the stock intake isn't a restriction.
What kind of mpgs do you see in normal driving.

My plans for this build were to keep the induction system the same as it always has been... Z-tube and a K&N filter... stock. I wanted to see what gains I got from just the motor upgrade.
During the dyno runs on the new engine, Jeremy noticed that the engine was still drawing a vacuum at wide open throttle. Additionally, Jeremy is not too fond of the Crawford intake plenum. I tried to purchase a Cosworth plenum while my car was still on the dyno, but couldn't find one. Since it looks like pretty good evidence showing that my car needs more breathing ability, I'm looking in to several options there, too. In all honesty, if I never made another mod to my car, I would be very happy with the power the new engine makes.
I haven't checked the mileage with the new engine. I filled it up right before "The Run" last weekend, but I suspect the amount of "spirited driving" on the back roads has doomed this mileage test to failure. I used to get 18.5 mpg in the city with the 4.08 gears and my old engine. I suspect I will get a bit less with the new engine.
