I`m with you bro on auto`s eating dyno numbers up. But from a dig I bust that *** in my 408! I love the power and no shifting. But from a highway roll it isn`t so good unless I spray, lol! Put a 150-200 shot and you will roll out!!!! I will be getting some track times soon myself!

Glad you got it moving forward. That pig is never going to hit great numbers with your kinda weight. I dont see the logic behind making in not street friendly in the TH400, etc and not pulling the weight out so you can run a good time.

New Nitrous numbers......
Changed from a 150 shot (dyno'd 565rwhp) to a "200" shot and went to 707rwhp.....
Also, on the nitrous tune it did 438rwhp and on the motor tune it does over 460rwhp.
Now I need some tires to harness the 700+rwhp!

That dont really suprise me I think these heads are so big that with our comp. ratio it just isnt enough to make good NA #'s. but when you fill those cylinders with nitrous the bigger the gain. mine picked up 132RWHP on a 100 shot and the car spun on the dyno.404 RWHP to 536 RWHP.

NA is 28
150 shot was 22
200 shot is around 20 or so.
The standalone has 109 racegas in it. It seems to work well with that timing since the plate distrubutes nicely and it has 7 range plugs. From what I gathered from the tuner.
That way you can have both tunes on the touch of a switch.

Rick, how is this done? or How much?
You still have my number? The car feels awesome with 465+rwhp on motor.... but when it is on the 420+rwhp nitrous tune it doesnt feel as fast. Seems like a very noticiable difference!
