Yeah when I see bolt on C7Zs going 9.90@136-137 mph in good air, then the same night I see a cammed, F1A C7Z going 10.20@137..... I just shake my head.... $5k in bolt ons or $10k in a blower swap, + a $3k cam job...
Now I HAVE seen some F1 cars getting into the mid to high 9s but.....not near as common or easy as the stock blower cars, believe it or not... But if you want to go faster then 9.60s, you HAVE to do a blower swap...and a converter, and a cam, and blah blah blah....
You know how it goes from there.
No doubt a procharger car will yank a stock blower car out on the highway tho....

Almost a never ending story.. Robert

I have this exact issue on my car. ECS1500 w/416 makes 830whp+ at 12lbs of boost on the dyno. At the track it only made 6lbs when datalogged and ran 10.59 @136.
From what I recall, we fixed my throttle programming so its 100% now, but my tuner figured it was belt slip at my last track day. Its going to a new tuner in a couple weeks so hopefully it gets fixed up, whether its belt slip or in the tune.

John you were absolutely right...
So I just found out it was the tune. I took it to Joe @Cordes performance and they got it all dialed in... I haven't taken it back out to the track yet but the car is a complete animal now on 17lbs of boost

What specifically in the tune was causing the issue? My car is going to a new tuner in a week and knowing what to look for would make things much easier.

Thanks

Definitely not belt slip. New tune didnt fix the issue, and datalogging isn't showing anything obvious. Its holding timing, fuel pressures are good, doesn't look like its retarding anything, throttle is opening fully. Sending my tune file out this week to a bigger shop with more C7 experience to see if they can find anything.

Okay... SO I've learned a lot in the past few months... First off that a simple dyno number although great to have a high one doesn't alway equate to a good 1/4 mile time.... That being said Joe and his crew at CPR added a cam, converter, fore low side fuel system and Ethanol conversion to go along with the original F19A Procharger and meth that was done... I gotta tell ya I can notice a very big difference to go along with the
950 whp that it put out but the proof will be when it's not an inferno in AZ and we go to their track event in the fall with them to run it.....
Thanks for all the comments guys
