I recently purchased a used 2.9 Whipple for my 2012 GT500. Seller claimed it had 3k miles on it and overall it is in great shape. Only thing that threw me off was the oil in the blower was black when I received it.
I did the install myself and put brand new oil from Whipple in the blower. Took the car to Shaun at AED for the tuning and left somewhat disappointed with the numbers it put down (I know it's just a number, but still). Final was 618whp
It has the 3.25 pulley and is making 17psi up top. Per Shaun's recommendation, I blend race gas with 91 octane which is what was used during the dyno. Timing was at 21 degrees. I was expecting at least 650whp with these specs, any insight on what the issue could be?
Shaun couldn't squeeze any more power out of it. For reference, the car made 560whp with the stock blower and 2.5 pulley. Other mods in sig.
