Damn I love you and your builds Robin. I'm dying for the new HRM to hit the stands.

times are almost identical, they backed down the nitrous after adding the ported heads and test pipes. so basically, now its making more on motor alone.

I backed the Nitrous tune down to achieve the same MPH at the track so not to run over the limit of the pump.
Lingenfelter is looking at ways to install a controller that can drive a larger pump. I could certainly turn up the tune to get the numbers but we have to go rounds with this. It can't be a dyno queen or one hit wonder.
We have plenty more in store.
Next will be a Vortech Supercharger then installation of an LSA.
We will upgrade the clutch at the same time as the Vortech.
The lack of a gear is going to be our biggest hurdle. Still it's a lot of fun.
Everything we are doing is geared to the average person wanting to do bolt on performance enhancements.
No trick stuff here.
