Hello Guest, welcome to the initial stages of our new platform!

Did you change the cam timing at all?
The ipd cam wants to be 3-4 degrees behind straight up. Real tdc on it is at 1mm lift at crank TDC. Bet you pick up power everywhere that way rather than just shifting the powerband around.
Does this apply to 8v applications as well? I have mine straight up right now dialed back from +1 I originally had set.

Do it!there's also the sudden desire to do an intercooler test and verify that the npr is all we believe it to be

I have an ipd cam and sts gear....was unaware of the best way to advance/retard it

I am only really concerned with power from about 3700 to 6200. We stay there all day long. Getting from 5500 to 6000 seems an effort with the IPD cam straight up.
6000 is not a place where a stock 8v head will make power, generally speaking.
Or it's a hold over from when it seemed every aftermarket cam was ground with 4? of adv built in...
There are a lot of places on the tracks we race where it doesn't make sense to shift from 4th to 5th as you near the end of a straight. You just keep it in gear with the foot down until you brake or hit the limiter. *shrug*
so I reckon the takeaway is I need to get an adjustable cam gear before I toss this 8v head aside?
