race truck's new setup

01PSD · Dec 1, 2011

From what I was reading on CompD Aaron wants to push for fuel only now

Jeff@Spartan · Dec 1, 2011

Didn't the old setup do 9XX on fuel on this dyno? I would assume that with the current setup (once the bugs are worked out) 1,000+ fuel only isn't even in question. Add the 104mm to the mix and 1200 fuel only should be doable.

Wow i guess i wasnt even in the right frame of mind...

Any plans to add nitrous again in the future, or is it pretty much set up for fuel only now?

This is just my guess. I mean if they are already at 930 on the 95mm atmosphere not tuned in precise, just imagine what they will be at with the 104mm billet tuned in :toast:

Just a matter of tweaking and tuning :evil
I keep telling myself to make the hour drive north to see this thing in person LOL

You should! I drove 12 hours to see it. LOL

I saw it make a test run a month or two ago here at a local 1/8th mile track, sounded totally different in person that's for sure. Can't wait to see it in action now!

Btw, all this stuff was using some pretty basic tunes that we had just to turn off a bunch of codes...

Guys he did 930 on 3/4 throttle. Their still ironing out the kinks, as it sits I'd be willing to bet this truck will do well north of 1000 on fuel no problem at all.

Basically blew the headgaskets on the dyno, studs were wore out and was probably our fault for reusing them. Took about 7 hours to change out the heads and gaskets and we left down for PRI without really running the truck. Drove it around the parking lot before we took it down the track and everything seemed good. First pass was 6.7 which is .1 away from our best fuel only time ever, not too bad for the first pass. Second pass was a 6.8 and something locked up on the bottom end of the motor. Either bent some rods or spun some bearings. FYI, stock motor and heads do not like 100+psi. It's still sitting in the trailer, waiting for the race motor to be done. We will keep everyone posted as we make a few changes over the winter.

I guess you found the limit finally! LOL

Ill be curious to see what exactly failed on the bottom end of the motor.

Pmr rods like to break before bending I'm wondering if it spun a bearing.

Good luck on the engine build and keep us posted. Going to be rowdy!
