Now. Back to the fun times. Party tires back on, we're going to the track!





I had noticed that the injector duty cycle had gone WAY up at the same boost levels. So I had a good idea the freshened up motor made a fair bit more power but I had no idea it was that much. The previous best 10.36 @ 136 was at 24 psi. I ran it at 22 psi all night this time. First pass straight off the street, soft launch, short shifting was a 10.13 @ 139! Wow! Huge gains! I turned the launch up 400 rpm and shifted higher. And was rewarded with............



Heck yes!!!!! Finally in the 9s! And at 140 mph!

Went back around again and another one! 9.97 @ 140 mph!









Best part is that I got to drive it home and didn't work on it the whole time!

And what do you do the morning after you run your first 9 second passes? You hook a buddy's turbocharged hyrdo to the back of it and go for a boat ride.









And another boat on Holley EFI that I got to tinker on.

Heck of a summer so far! Thanks for posting the updates here.

I've caught bits and pieces elsewhere but still read all the way thru again here.
