Havent been messing with the car much lately so I went ahead and put the 4.25 pulley on the F1A (7.25 crank) and figured I'd see how it would do on a typical 85 degree 70% humidity day around here. DA was 3400' or so, raceweight was 3397lbs.

Not bad for 15psi on a hot, humid day in the mountains. After 30passes or so on the new LS2 it doesnt appear to be makingmuch more power then the old 347. I was hoping the fresh heads and 4" bore would pick up a little but it doesnt appear so. Good thing is it hasnt pushed a drop of water which is a good thing. Nothing too exciting but hey its a free video

Nice runs!
Now I am motivated to get off the damn computer and get working on my front suspension mock up!
Keeping water inside the engine is a good thing, you make it look easy!

Thanks for the inspiration!

Is it just the video or was it coming out sideways?

Nice runs either way, I was supposed to go to the track today but its not looking good.

Thats mostly my fault not staging the car straight or being out of the groove, it will go whichever way it is pointed pretty darn quick. For some reason I always want to stage it pointing a little left, its hard when you are sitting low in the car and cant really see the hood at all.

Interesting information KP.

Do you have numbers comparing both set ups? How close are they in regards to MPH and ET?

Thanks,

Well here is the 347 with the F1A 7.25/4.25 almost exactly a year ago at the same track, only difference was the car is around 60lbs heavier now. Almost the exact same weather as well. Boost is exactly the same on the logs and the RPM drop/IAts are almost identical. Thats what happens when you change only one thing on a very consistent setup

You should bracket race it! Nice runs, defintely looks like it kicks to the left every shot.

The camera angle and the relation the wall makes it look worse than it really is. Its the nicest driving 1.26-1.29 60 foot car I ever drove

Air shifter really helps that out a lot, now I can play with teh radio going down the track

It is amazingly consistent for a small tire blower car though.

Kevin you still running a 3.70 gear?? How do you think it would run with a 3.50gear?
Man that thing sixty foots hard.

kp

iTrader: (34)

Tried a 3.50 and the converter got a little too loose for my liking, I need to move up to a 9" converter if I want to run a 3.50, so the 3.70 is back in for now. Yea, the car 60 foots like a low 8 second car, too bad I really dont make any power. But thats the beauty of a centrifugal blower IMO, people complain about the lack of torque but for me it works just fine..

Still learning but do you think your D1SC 60ft harder on the same boost levels as the F1A?? Since the F1A has a higher internal gear ratio opposed to the D1SC's 4.10 would that mean the D1SC makes boost sooner in the lower RPM ranges.
You've experienced with both blowers whats your thoughts?
On the Foot brake how high does it let you stall it too, and what RPM does it jump too?

Sorry for so many questions, lol.
