Made a few dyno pulls...

I made a few pulls on the dyno, and figured I would share some preliminary results. Our first pulls were on motor only to set the base VE tables.

495 rwhp @ 8200rpm this is a s/c motor with low compression

After a few motor pulls, we put the belt on the s/c and made a few attempts to get a reading. We could not get the motor over 6200rpm without loosing the blower belt. I will say it did feel strong when it would flash the converter and start making some boost!

872 rwhp @ 6200rpm this was with 12psi and lost the belt way before our 8500rpm projected rpm limit.

We'll get the belt situation sorted out soon, and be back on the dyno in a few weeks. I'll post an update then.

400ci Little-M
Crower billet crankshaft
Crower billet rods
Custom CP Pistons
Good heads and intake
Vortech X-Trim
TH-400
12 bolt
And a few other misc parts to make it run



Sorry but.....
I am selling a set of 8- 83 lb/hr injectors. These have only 10 dyno pulls and 3 passes since being cleaned, serviced, and flow matched. I had to upgrade to 160's while on the dyno, and no longer need these. Trying to recoop some of the money spent on the 160 pounders, $450.00 or best offer.

Got any pics of the setup, specifically fitting that enormous thing in there? I'm assuming it's not mounted in the traditional location. Awesome numbers, definately some room to grow with 2300 rpms and hopefully at least twice the boost. :)

You maxed 83#ers at 875hp?

There is still a lot left in her! This thing should see @ 25 pounds of boost when it is all said and done. I hope to be over 1000rwhp. Keep in mind the brake specific on a supercharged motor is much diferent than a turbo motor due to the enormous parastetic loss. It will also see @ 9000rpm through the traps.

Birdie2000,
I'm sorry, I should have mentioned this was in a third gen Firebird, I can e-mail a few pics if interested.

please mail them to camaro@z28a.com also...

Just out of curiosity, why are you reving this motor to the moon? Plenty of power can be made well below 7K. Just wondered why ya went this route?

This is a pure drag car, it was built to compete and be compeditive in Vortech Extreme Street and also some drag radial stuff. The X-Trim likes to be spun hard, take a look at the NMRA drag radial guys, and you will understand why it is set up this way.

P.S. I will send a few pics out this evening.

that looks badass :cool: Intercooler sitting in the passenger seat area I take it?

god DAMN. Looks gorgeous!

VERY, VERY, impressive! I'm sure that is a fun ride.

damn i was wondering what happened to the batmobile. :lol: :thumb:

Wow, great setup. Looks good too :thumb: Can't wait to see some track times. I bet that blower sounds MEAN at idle too.

That has got to be one of the sickest 3rd gens I have ever seen ! :D

Thanks everyone!
Lots of time has gone into making it what it is today. I am anxious to get the minor issues straitened out and make some passes at the track. Hope to make it to a few PRO and NSCA races soon.
DonB.

That is an amazing setup....good luck on getting your belt and other issues fixed!

Damn Don that thing is looking good man :bow:

Should be good for a low 8....I bet you can't wait to make a pass after being down for the last couple seasons. BTW, when do you plan on making your first passes at Cecil? I would like to come down and watch.
