the SDCE uses a 7.25, I usually see around 7250 through the lights in the 1/4 so thats about it for the F1A. I have tried a 3.7 pulley for 1/8 mile but it gets too hot for me.

With the 3.9 at 3800DA a couple weeks ago I only seen 15.6psi @ 7000rpm which is a little lower than I expected. Car ran 5.82 @ 122 in the 1/8 which isnt bad for that weather and the tires being gone (1.31 60') plus I added 100lbs with the 25.5, air shifter and fire system. But I was hoping to get to London Ky in some cooler weather tonight with some new tires. Its possible I may be running into some inlet restriction with the bigger engine also, boost seems to level off pretty early but maybe the blower is just done also. But I need to get into some better air to see and thats tough around here this time of the year.

 

That is a monstrous intercooler. It'll be interesting to see what it can really do with a good converter in there. What's your race weight?

 

Per XS rules it is a hair over 3400 with driver.

 

Bob, Have you already recieved your July issue already?

 

Yes, sort of. GM High-Tech air-mailed it in a package to me and I received it Friday. I have not yet received my regular subscription copy. Bob

 

Wheelie? You guys can pull the wheels in that slug?

Looks good guys! So what's next, an F3 & 7 second slips?

 

LoL, f3 and the heads would pop off lol. Defiantly not built for 7second horsepower.

I think the transition to the w2a is not that much heavier then the a2a. The core+brackets weighs in around 30ish + water. Thats the killer right there, dang water weight and the pump/tank/lines, but iat's that are less then ambient arent to shabby

 

Good pic from last year. Bob
