The last 2 runs today at Runday Sunday at BMP the DA was around 550 and the car went 10.46 @ 130 and 10.48 @ 130.3, track was not good in the morning(spining off the line). The WOT tune is close to good but the car needs some driveability tuning. Last year in similar weather around 500 to 700 DA the car would run in the 10.60 to 10.65 range at the same race weight 3520lbs, that was with the ported L76 intake and 92mm Fast TB. It would seem like the Fast 102 and 102mm TB are worth about .15sec and about 1.5mph on a SDPC LS3 427 w/PRC cnced L92 heads, 236-248 cam, 1"7/8to 2" Kooks headers, WCR built A4 ( in an 02 Formula).

Still seems like too much money for those gains. It was not an exact comparison, an intake swap at the track would have been. The ET and MPH gains could be from either the DA difference or 60 ft times too.

Thanks for being the first to post drag strip results but they are still inconclusive.

It is not an exact comparison but the car 60's 1.50 very consistently if the track is good( those 2 runs were 1.503 and 1.504), i bracket race this car and have over 250 runs on this exact set up. I keep records of all my runs for bracket racing purposes , so i know what it will run in most weather conditions. I am usually within .01 to .02 on my dial-in.
It definitely picked up over .10 and over 1mph from the Jeremy F ported L76 but that is a pretty expensive gain. That is also the last thing i can do with this set up for better ET other then doing a crazy 5000 stall converter , or a big terrible driving cam, or going with non streetable 4.10 gears.

Thanks for the results. Those real world results are just what everyone was looking for.
