We went to the track last night, had a great time while it lasted.
So this kit/truck laid down 711hp and 847tq on 12psi.
For the track we decided to turn it down to 8psi since fp was dropping. On 8psi it ran an 11.8sec.
Between the shop and track, the owner fixed the second fuel pump, so a/f ratio was 10.0 or richer due to a lot more fuel, so that pass was on a very rich tune and only 8psi.
At the track a boost controller was installed, but around 9psi, a trans line blew, so the night was over.
We're heading back out to the track tonight with 12+psi, or whatever the fixed fuel system can handle.
I'm pretty confident with 711hp and all the torque will get us into the 10's, maybe not tonight, but after some fine tuning and adjustments.
With more timing and more fuel, I think 12psi will put out 800hp. The 711hp dyno run was lean at the top and low on timing, due to the lack of fuel.
btw, this turbo sounds incredible! It sounds better as the boost is turned up and responds great! Sounds and feels like it would be comfortable right at 20psi.
So first time out, 8psi, 11sec pass, only got to run it twice.
more results tonight.
