I'm not even sure when/where I could get onto a dyno around here, two places I know have one don't allow diesels because of soot/smoke

Found it!
For anyone that's curious: BIG DYNO DAYS #'s
There's Typ4's chart, I believe the two lines on there are Justin/R&D being the higher one and Typ4 being the slightly lower one.

It's also interesting seeing how the curves end up - Looking at it, I'm seeing peak torque at 461ft-lbs at 2100, peak HP 'flat spot' around 2600-2800 at 218.

Mine, I'm only making 350 ft-lbs at 2100, hitting peak torque of 453 at 2750 and peak HP 'flat spot' around 2700-3200 of 245, defueling around 3300...

I'm guessing the much better low-end is due to the Typ4 cam? I *so* want to get it onto one of my setups and see what it does.

The Typ4 cam is a nice cam. Just installed it in my friend's truck and it is extremely responsive. Also just wanted to point out that dyno comparison is with the J2 cam.

Make you sure you have the fuel to push a stage 2 turbo, you need the 110cc at the least.

There are actually some guys running an S366 with a 90cc pump. They actually spool decently. But more fuel is definitely better!

I guess so, is that the waste gated one? He told me that you would get better performance out of the non wastegate stage 1 with the 90cc. Thats what I plan to do after some body work.
