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.

There is a loss of the peak torque number when using the short runner intake compared to the usual LS6 manifold but, up high this intake makes alot more HP. Remember this is a solid roller/jesel set-up that spins about 7500 rpm.

BTW the NA torque # was 49x...can't remember right now..

490 to 700 is a good gain.

forgot about the sheetmetal intake.

any chance of some pics.

Some real kick *** numbers there, but I don't see that block taking that kind of abuse too much. Not a flame to MTI, but no matter who did the block, they just won't hold that kind of pressure long. But hey, it WILL kick *** while it spins.

Few questions to the guys at MTI.

1) On the nitrous setup, is it using direct port on that custom sheet metal intake, or just the two TNT nozzles?

2) How big is the nitrous shot for the 1st stage and 2nd stage? Are they both wet shots?

3) Was there any race gas or octane booster added for that run? Or is it just pump gas?

4) Is it using an aftermarket C5 fuel pump? If yes, which one.

Thanks guys. I can't wait until you finish with my iron 408 motor.

Cheers

My CF question was pointed to the temperature and pressure readings as printed on the dyno chart...those aren't the points at which the SAE correction factor considers "ideal" (or for a 1.00 CF). Am I incorrect in that observation?

The 1st kit is jetted for 150 to the tires and the second is jetted for 100rwhp. The car has it's own custom stand alone fuel system with a 1 gallon fuel cell in the rear hatch area where the CD changer usually sits with an external pump mounted underneath the car pumping race fuel to the fuel side of the N2o system when activated.

Wonder how much power you guys would put down with a FAST SEFI system and a 3-Stage 300HP DRY setup on that monster?

Fuel and N20 control is soooo much more precise with a SEFI and real time wide band correction...

RyanJ

how did i know JS was gonna mention 3-stage dry and FAST. tell us about your firehawk! just kidding.

FAST will not work without the Edist box thats not out yet (that i know of).

Damn impressive MTI. These guys never stop impressing me. <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />

BTW, My lil H/C/I TNT stock bottom end still made more torque <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> on a 100 kick at that <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

I can't wait to see what that thing runs!!! When I was down in Houston this past weekend I had a chance to see this beast on the dyno - All I can say is WOOOOOOOOOOOHOOOOOOOOOOOO!!! <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" /> And that was just the NA run. Going back to Houston every 2 months is definitely good for my soul. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

Does the fuel cell seal pretty good? Can you smell any fuel inside if it is installed in the back of the car?

Mike, thanks for your speedy response. I'll stop by tomorrow. <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />

Another question to Mike@MTI.

Did you guys have to "O-Ring" the heads to the block?

Thanks

Hey Tony,
How about an NA graph?
Also I know Stacey had LS6 intake with hyd cam before. I’m sure those runs are still on MTI computer.
Any chance you can post a NA graph of this setup over the old one?
Just curios how this intake change the power band.

Thanks.
