MTI 422 + Nitrous = 807 rwhp This Corvette belongs to Stacey Barnett in Arizona, his car was recently at MTI for some more "upgrades" since his last setup (ran 9.90s @ 137mph on his first track visit). That was about 100 rwhp ago <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
Mods:
MTI resleeved aluminum 422ci
MTI Stage 3 LS6 heads
MTI custom solid roller camshaft
custom sheetmetal intake (short runner)
all bolt-ons
MTI custom dual-stage wet nitrous setup
6-speed Corvette
NA dyno was 540 rwhp (19 degrees timing for nitrous). Here is how the dual-stage nitrous dyno curves look:

807 rwhp @ 6500 rpm
Here is the VIDEO of the Dynojet run.

Track times coming soon, maybe in a week or two.

Re: MTI 422 + Nitrous = 807 rwhp Awesome power! Right up there with what Brooke made with his "glass" 346 a few years ago, LOL.
Tell Stacy congrats for me. That's really cookin'.

Re: MTI 422 + Nitrous = 807 rwhp Tony, awesome numbers!!!!
Any more details regarding the "sheetmetal" intake? Who makes it, what was the power change and has it be tried on anything else?

Re: MTI 422 + Nitrous = 807 rwhp Jeez . . . this setup makes mine look positively tame. Dual stage nitrous with solid roller 
That car is going to be a turbo viper/supra killer if I have ever seen one. So much torque.
I'm liking solid rollers more and more based on what people are getting out of them. Just that whole valve lash issue . . .
