Vinci XXX cam
Well the results are in. I dragged the car for the first time at the corvette forum cruise in and also put it on the dyno.
I wasn't expecting it to hang on so well in the upper RPM. A couple of guys were trying to talk me into raising the rev limiter. There was a small flutter in the upper RPM but it was only on one pull. The other two pulls were nice and smooth. It was a blast on the track but I couldn't get it to hook.

nice numbers. looks like there is more to be had. the a/f ratio looks to be in the 11:1 area. needs to be leaned out to around 12.5-13:1 area. would get you closer to the 400 rwhp mark.
keep plugging away at the launching and you should see at least a 12.4 ET.

From that mph you should be in the low 12's at least. You have to get that 60' lower. You should be able to get it into the 1.7's with the 60' with the proper mods and tires.
Anyways looking good with a lot of potential in the car.

Everything else about the tune is excellent and his rate was reasonable.

I'm not offended, just wanted to explain since I didn't above. The tune was performed without a dyno. The above graph was from the cuise in, I just wanted to see what it had.

What heads are you running? The only reason I ask is because I'm running that same cam with AFR 205's and I'm only getting 365 hp on an A-4. It looks like your there with the stock heads?

I'm running stock 241 heads. Those numbers of yours are definitely low. The numbers I put up were in 90 degree heat to boot. How does your car do at the track?
