Although the time he reported is sketchy at best.
I thought maybe he had some secrets on how to get a stock GP to run a little quicker poor/unofficial timing system and a homemade drag strip seemed to be his strategy.

Here is the PM I received from him:

I never ran stock, but with a home build CAI I ran many 15.9-15.8 1/4 mile runs at Pittsburgh Raceway Park. After adding a tune, HV3, PEMS I ran a 15.6.

Very respectable!

With that said it ran a best of 16.319 @ 83.17 with a 60' of 2.282.

Not bad for my first time racing and being full street, so if you get a good launch and do track prep it will be 16 or lower.

(PS. Your Series III should be nearly identical to my set up other than the CAI since the S III TB has the same size opening as my ported TB.)

Mine always trapped at 88 or 89 MPH stockish.
