Turn the boost up and see what happens. Mitch might be on to something with valve float, top end still looks kinda ish.

 

as already mentions the clutch is already having issues @ 550 Trq and the MAP sensors limits it to 31 psi

 

If the MAP sensor is holding you back, have them pull my 4 bar out of my car, its at MAP now and try it

I assure you that after you see results on 34psi or more you will be like, OK I'll spend 100 bucks on an omni 4 bar

 

Maybe when I get a good clutch pointless to play with more boost if I'm gonna strip the pads off lol

 

Exactly why we didn't go any further

 

MAP - thank you for doing back to back tests of the products installed on his car. amazing what a few parts can do to help the powerband.

#s look great.

 

Pretty much what they are saying is that it is not unlikely that you are experiencing high rpm valve float. '25-30 should be fine'. You have large lift cams and are pushing the maximum limit per supertech. IMO clutch then valvesprings. Stop buying other parts! lol

 

Im sure the clutch is right around the corner the ACT will only be able to handle 550 so long

 

Map- thank you for the back to back results!

OP- Great car, great build you're def. on track

 

Nice numbers! Just curious as to what your IDCs are.

So I upgraded the pressure plate and disc. I was wondering if I can just use the MBC to turn the boost up without getting a new tune?

 

Assuming you are on the MAF still, in theory you can do that and the MAF will calculate for the extra air.

However, I always think you should tune for max power and dial it down if need be. Tunes are cheap insurance.

So in short, if you aren't good at monitoring/logging just get a tune

 

are you still running the ttp 6 puck?

i didnt have any slipping issues with the act sprung 6puck, however it did $hit itself after ~18k DD driving @ ~550/580 ft/lbs of love, every chance of clear road that i was presented with!

 

No I upgraded to a unsprung 4 puck and the Modified extreme Pressure plate.... no issues now lol but I'm still at 475 awhp. My preassue plate was pretty wore out before. it's had about 35000 miles on it
