How do you keep the fenders on that Chevy? The wind is going to rip them off!

Congrats!

I thought you were maxed out on those rods & not going for anymore boost?
How much boost are you guys @ now?

We did not put any more boost to it. The same 22psi we have been
running for the last few races. The convertor was 80% of the performance gain.
We are not over heating the transmission fluid anymore. We covered the grill to keep the air out.
Put the wheelie bars on. Added the "bull horn" exhaust to keep the front down. We are learning how to use the power we have.

Ok,
that is good to hear the converter is working that much better.

How much is the stall now?
Brake stall & trans brake stall RPMs?

Your 60' is better also correct?

It was a 3800 rpm stall behind our nitrous motor. Coan pulled 500 rpm of stall out of it. So that would make it a 3300 stall but we can foot brake it to 3500 rpms. The trans brake rev limiter is set at 4500 rpms to launch. What works for us will probably not work for anyone else.

Sounds good.
I am not trying to copy your set-up.
Just like to hear about peoples builds.

What is your 60' times?

What is the boost pressure you are launching at?

On my Syclone, normally my torque converter brake stalls to 2100-2200 RPM.
I was doing some datalogging w/my Syclone & was really surprized on how much my stock converter actually brake stalled to.

At 19 PSi, the engine RPM was @ 3025.
Converter is just as tight as ever, I guess having an engine making 560 ft lbs of torque is going to make something give.
In this case, the converter was doing the giving. \:D
My poor old stock original 700R4 is past it's limits. But it's still hanging in there, don't know for how long though. \:D

1.30-1.31 60'

Launching at 10 psi @ 4500 RPM.

We are going to try and get the 60' down pretty soon. We feel like the racing surface is the limiting factor not the tire.

It's been a long time sence I posted any thing so I thought I would share video from this weekend. It was the LS1 truck shootout. There was a "fastest truck on the property" class. So we ended up racing the fastest LS truck at the event in the final for the win! The track was a bit marginal at best compared to what we are used to racing on. A fan offered to make this video for fun and we think it turned out pretty good. Enjoy \:\)

Didn't you run in the 7s last year? That must be quite a ride. Not very aero for those speeds.

No, 8.40s was all we could get out of it. We think in perfect conditions we can run .20s but there again "perfect conditions".
One person told us "just turn up the boost"! Well if we were runnning 11-12s that would work but low 8s is not the same.

Were staying at 21-22psi. At this event we only running 19psi. With so many events going 1/8 mile its hard to find a 1/4 mile track that's good. They run all the street cars down them and the surface is cr-p!

We had it as light as 2850lbs but it will not go down a bad track at that weight. Its at 3000lbs now with 150 extra lbs hanging at the rear.

We went to another local truck race this weekend. The black truck was the 8-9 sec bracket final. The s-10 was a lil grudge match to keep fans entertained while another class was lining up.

1320 video did all the camara work.
