Default Turbo 5.2 Dyno.

I know, not a Ram, but since Rams make up the Majority of Magnum engines, I thought I'd share.
290RWHP, 375RWTQ (on a pull not pictured on the dyno sheet). It needs heavier valve springs badly as exhaust pressure and boost pressure are blowing them open around redline.

What all have you done to the motor? Just the addition of a turbo? and the stuff in your sig? (I.E. no internal changes?)

Very impressive. I'm liking the relatively flat torque curve, especially at 7psi. How much fiddling time have you spent setting up the Megasquirt and turbo? I'm thinking tow beast extraordinaire. I wonder how things would look with the keg. Surely there would be less on top but would low RPM be even more tractor like? Nice job on that thing!

I don't think runner length makes all that much difference on bottom end when running a boosted motor. Now, the long runners would more than likely lose you some top end though...... (run more boost. )

I do have a quite a bit of time invested, but now that I know what I'm doing more or less I could do it much faster next time.

And notice the first pull didn't have enough load on the rollers so it spooled late, notice how flat the torque curve is out of boost and how much torque there is with the M1, stock is 300 at the crank, I'm making 250 at the wheels out of boost at 2000 RPM, as I've said with a good tune and supporting parts the M1 torque loss is negligable. The keg will only hurt top end.

how much work/hard was it to do the turbo and how much money did it cost?
