MTI 427 dyno results... UPDATED
First off thanks to Jayson, Mike, Lloyd and all of the MTI guys. They put in extra hours to finish up my car so I could get back to Austin on Saturday, they worked until past 7 friday night and met me back at the shop at 7:30 Saturday morning!! All that work so I could get back to Austin on Saturday to get drunk on my birthday. <img border="0" alt="[chug]" title="" src="graemlins/gr_chug.gif" />
So we put it on the rollers to make 500 rwhp on the first pull with no break in! The best pull was 502 rwhp and another made 505 rwtq. The specs and graphs are in my sig. There should be a little more power with some break in and a few other things may need to be changed that may be restricting flow.
Also that is through a Cartek clutch, Denny's driveshaft, 12 bolt (4.10), and 17x11 wheels.
The power is eveywhere, right at 500 from 5500-6500 & torque is above 400 from 2600-6500. The only problem was that it was making a loud squealing noise when we got it started up Friday night. <img border="0" alt="[bang head]" title="" src="graemlins/gr_banghead.gif" /> Mike pulled the tranny and the clutch to find the seal on the back of the crank was melted and everything was perfect after he replaced it. <img border="0" title="" alt="[Cool]" src="gr_images/icons/cool.gif" />
This thing is sick on the street!
Now I need to get this beast to the track! <img border="0" alt="[driving]" title="" src="graemlins/gr_driving3.gif" />
Thanks again to everyone at MTI. <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />
UPDATE (2/22):
It looked like the Stealth Airbox wasn't fitting up well and we thought that maybe the traditional MTI lid would flow a little better.
We baselined the car at 498 rwhp 481 rwtq. I had just driven in from Austin so the car was a little heat soaked.
I pulled off the Stealth box and replaced it with a stock lower airbox and a MTI lid and we dynoed again. It gained 11 rwhp & 13 rwtq!! That put it at 509 rwhp & 494 rwtq.
I'm gonna try to make it to the track tomorrow.

AWESOME #S MAN CONGRATS! You REALLY have me PUMPED UP as MTI is finishing up my 427 Z07 ironblock Stroker utilizing the same compenents in your 427 resleeved alum. block. I am usig the 4.125 crank and 4.060 overbore.
I am going thru my A4 so rear wheel hp numbers will not hit 500 but the torque should be out of control with 4.125 crank. Did you use the S1 cam i assume on a 112 lsa?
DId you happen to see my baby there (pewter C5 convert with black top and black 6 pt rollbar) waiting for HER NEW LIFE & HEART!
I'M NEXT!!!!!!!!!!!!!!!!!!!!!!!!!
Best of luck to you and now get those 10 second something time slips on MOTOR! <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />

Thanks for the compliments guys!!
MTI 427 C5 Roadster, if your car is there I probably saw it. I just don't remember, does it have black Z06 wheels?

The cam is a Comp XER 250/244 .622/.612 112. It sounds MEAN! I pull up to stop lights and jaws drop. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> The exhaust is a x pipe with dual bullets dumped before the axle.
Greg, I am planning on making it to the Shootout. I need to make some shakedown runs sometime betweeen now and then.

Congrats Justin! I expect you to smash my slow ET on your first visit to the track, maybe even the very first pass <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> .
You will enjoy dumping the clutch at a much lower rpm. It only takes 4500-5000 rpm to cut 1.4s with a big motor.
