Power+weight+time.
gtpete:
That's some quick cars. Both 1800 lbs too. Thanks for the replies looking forward to some more :)
JrFuel Hayden:
We race NHRA Heritage JrFuel for 17 years same car was 200" WB when first built by Dave Tuttle in 1998, and we front half the chassis in 2011 when tried an early Hemi and went to 225", max WB for the class.
Car with driver weighs 1435 with the SBC, and 1500 with Hemi . We run mostly 7.00's in the 1/4, and 4.45's in the 1/8 at 153-155mph, and 1/4 speed is 186-190. Class limits are only pure alky, 12"wide tires , powerglide, all iron engine, stack injectors all at 3 1/2 lb per CI. Our engine location is 48" from back of engine to center of rear axle. The cars being built lately are 55-60" out. CI limit for JF is 430, we run 409 on the Hemi, and 400 on the SBC., but some teams run 387 ci SBC. One option we have in JF is we can also race NHRA Comp Elim, in A/ND [JFA] or B/ND [ JFB]
Call if you have more ??'s 805-444-4489, Jon
George:
2011-2013 we ran a FED with SBC. Dynos numbers were 600 +. Car and driver were 1460#. Ran low 5s with good track and air in the 1/8th.
Curly1:
I would like for others in particular Jon Hayden to add front weights as I think it is critical to making these animals work. Mine was 1730 with 389 on front and simply was not hooking up. So it is back at chassis shop making a bunch of changes. We are moving weight back and changing engine angle from 2.7 down to .5 approx.
dreracecar:
These days Engine angle has zero affect unless you were way out of the park to begin with. Engine angle is the result of the relationship to how far the motor is out from the rear end to the front oil pan clearence. We are raising the front of the motor these days so that you dont tear up the diaper. Building a new chassis right now, motors out 55" and the crank snout is 10" of the deck, I dont care what the motor angle is
