Hey guys so i finally got around to taking my car out to the track. I would say for the first time it ran pretty hard. The car is a full weight, full interior, no transbrake or 2 step car. I have a twin 6266 408 motor with a PTC 3500-4000 converter 4l80e. The passes made were at 10psi and leaving in no boost at all. My buddy didnt bring my laptop so i couldnt adjust my fueling at all. These runs were made in 99* heat of the day on pump gas(91) and a 625ml nozzle of 50/50. My AFRs were ~10.9 the whole pass and ive got 16* of timing in it.

The best full pass i could get before getting told to slow down for no cage is a 10.0@147 with a 1.5x 60'. After getting the threat I made a few 1/8 mile passes that were 6.2x.

I have the car at the shop getting a cage certed for 8.50 and time to turn that boost up to about 20psi and let it eat and hopefully get into the 8s. I have a 2 step that I have installed for the next track day but I will see how much boost i can leave off the footbrake.

Congrats! That's hauling!

What RPM do you hit full boost with the 6266's?

full boost id say around 3k rpm. It hits very violent at WOT but at part throttle cruising it is very smooth. I had 7268 turbonetics on it but switched the the ball bearing billet 6266s and OMG talk about faster spool AND way more power up top.

Hows the 60ft would you say? I know it should improve significantly leaving on boost.
