HP estimate with track times?

As I don't have access to a dyno but have some times, can anyone estimate my rwhp? I ran 12.64 at 97mph qtr. mile, 8.06 at 89mph 8th mile and 4.15 0-60.

My 2008 vert gt is an auto with M/T et streets and a v3 at 8psi. Other bolt ons too, hot rod cams, etc. Tuned via email by Brenspeed.

thanks!

Your time and mph seems odd to me... 12.64 @ 97 mph???... My best time is 13.986 at 101.47 mph on street BFG's at Darlington Raceway and my car dynoed at 305 rwhp... I have a friend that ran mid 12's and 116 mph in his 2011 5.0 with street Nitto's and his car dynoed at 428 rwhp....That's why I questioned your mph...................Just my 2 cents...


I WISH I COULD GET RID OF THE KNOCKING NOISE IN MY FRONT END. I'M TIRED OF SPENDING MONEY ON IT... IT'S DRIVING ME CRAZY!!!!!!!!!!!!!!!!!!!!!!

The mph figure seemed odd to me too but the 12.64 is accurate.

Time seems accurate. Car probably makes around 420-430rwhp with this combination is nice cool air. The MPH is definitely off for some reason and I would definitely make sure to let the car cool down in between passes so that the engine isnt so heat soak. The more heat it sees the more timing its going to pull, so long cool downs are KEY with any blower setup.

Thanks,
Chandler

You should do a much better time with the mods you have, I did a 13.89 when bone stock, granted I used a G-force but they are pretty accurate
