Is there another dyno run that resulted in 430whp?

The dyno run posted shows ~400whp, just curious.

Thanks

Sooooo, why havent you turned it up yet? After 20 miles I turned mine up to roughly 35psi lol. All you have to do is a compression check to make sure the pistons rings are seated.

Everywhere Ive read said to do at least 500-1000 miles with low/no boost. But the biggest issue is the clutch went on me after 200 miles, not sure why. It was used so I'm thinking maybe a worn pressure plate. But I have a triple to swap just need to get it to a shop to get it taken care of.

Everyone has their own preference when it comes to breaking in the motor. My opinion and what Ive always followed, drive it like you stole it. If its going to break its going to break, be it at 20 miles or 2000 miles. As long as you have a good amount of compression and ring seat, youll be fine. Plus boost helps the rings seat
Never had 1 engine go from the handful Ive built.

Sad to hear about the clutch. I want to see what this car has in it.

Two different ideas really on breaking in a motor. I have always gone with the 1-2 hour break in of mototune. Here is more info:

Yup, I would agree with the above link. Total run time for me was maybe 45 mins at max between letting it heat up and then come down, then reheat and go.

Yeah I think i will be turning it up soon. Clutch is going in next week Im going to drive it a little, compression test and dyno.

New clutch on the other hand, I would break that in differently. Get a few hundo on it before you go too ham.

A brand new clutch will hold power doing dyno pulls just fine. You just don't want to launch with it or do any fast shifting or down shifting with it where it will slip.

Not where IT will slip however where the USER slips the clutch. You want to avoid these situations until it is broken in.
