Foxbody with built 6.0 shortblock, stock 317 heads, and edelbrock intake. It made 750rwhp at the local DYNAPAK on 16psi. Its been mid 9s @ 145mph on 18psi and 9.38 @ 147 on 19psi. Here is a video of it running low 9s at SAR with a little more boost. Its cutting 1.2x 60fts. Race weight is 3120. The car is Reckart/owner tuned. Runs good for a budget build. The dyno numbers are pretty close to matching what it runs at the track.

Chassis setup? The little sucker hits the tires and goes.
that's what i'm talking about! the car looks like it works great.
LOL last thing i heard was "He got a chute on that thing?" looked like a street car to me
the car has coil overs front and rear, 150s with 90/10s in front and 150s 50/50s in rear, lakewood lower control arms and double adjustable uppers. upr anti roll bar. and many hours invested in plotting the suspension. 3.08 gears
damm gets up and goes
Moves out nicely and runs strong.

According to all the calculators I have used with 750rwhp you will hit 9.368291017512504 @ 145.496120632034mph. From what youre saying his "mid 9's" run at 145mph was done on 18psi...not sure what the mid 9's are, but one would think that you will make more HP with a little more boost. On 19psi he ran 9.38 @ 147, but it made 750rwhp on 16psi and that will give you a faster ET according to the calculators?????.....it just appears that the numbers from the dynapack are a little high, if he made 750 to the wheels at 16psi, then he should be running a tad bit faster on 18 or 19psi one would think.Quote:

At the weight of his car to gain 1mph it takes 16-17rwhp.
Still looks like the dynapack is a little high. The numbers from the dynapack at 16psi say he should be running 9.36 @145.xxx and he said he ran almost a full second slower than that on 16psi? Just saying that the numbers appear to be a touch high. Even if the track prep was bad and the MPH was skewed because of that its still not measuring up to the numbers it made on the dynapack. Like you said the 143mph takes 712rwhp, so even assuming the MPH was high that run due to wheel spin that makes the rwhp for that run also high. So one is safe to believe that on 16psi the car doesnt make more than 700rwhp. Maybe it does on 19psi?
You can base rwhp off MPH. ET comes with a dialed in setup, good 60ft, good prep, good gearing, all that affects ET.Quote:

Calculator shows at that weight and rwhp it should go 10.06 @ 135.3. Keep in mind its a 6speed manual car. I'd say its pretty damn accurate.
The calculator shows 698.2rwhp.. 2.8rhwp difference and .1 mph.
