With everything being equal...how much torque does it take to get one of these bricks to go into the mid 1.5's for a short time?

Depends a lot on weight, gearing, and torque multiplication in the torque converter.  See the attachment (pardon the Chevy... it was a custom power curve).

Does that chart show 600HP to make a 1.5 second 60 foot time?

Thanks...need my reading glasses. Gettin' old ya' know.

Click on the pictures and they should be full size.

If you have an actual dyno graph I can replicate it.  This is how I "hyper-tuned" our Camaro into the mid-12s on a stock motor.  Dyno graph, gearing, weight = programmed shift points... just had to add some traction.

No, it shows 600hp to run a 10.4; it is making less than 600hp by the time it hits the 60' mark (the engine is at 5800rpm).  This is just a simple simulation, I was focusing on torque as per Brad's request, in a full weight street car, and Buick-like RPM.  Nothing more, nothing less.

Th second graph didn't show up until now.  I was looking at the top chart trying to make sense of it. Thanks!

Just don't shrink anymore Scoob.

I still think your tire height is off Jason. Worst case, take a level and go from the top of the tire to the ground to make sure it's right.

[good2win22]

Ordered another set of rear springs to bring down the rake in the car.  Couple of pics of the current front and rear ride height.  Probably not the correct place to measure the height but I measured just behind the front fender and right in front of the rear wheel.  Of course the tape measure case and the concretes are your constants.  When the springs get here and installed on the car I'll put up a new pic of the IC calculator to see how it changes

[good2win22]

Got the springs in. Moog 5413. Car is down about 3/4 inch in the rear and I'm sure it will settle a bit with time. This means that the rake on the car is now about 7/8 inch instead of 1 5/8ths.


Ran the numbers on the instant center calculator.  Keep in mind that the goal is to remain on the thrust line (redline) and be directly underneath the CG of the car (the little blue circle). This is as close as I could get it to that intersection. As the car sits now with me in it, I have a 57% front and 43% weight ratio. So it appears that the only options are to remove weight from the front or add weight to the rear or do both.  Thoughts?

[Charlief1]

This is why you need to scale the car to see where the weight sits Jason. 100 lbs in the right side of the trunk should do wonders for traction.

[good2win22]

I did scale the car Charlie.

You misunderstand me Jason. You got the car weighed but not scaled. Scaling will give you cross weights and front to rear bias as well as target areas where weight may need to be added, or moved.

Do you have Dave Morgan's book on suspension set up?  Door Slammers

I do not have that book. Looking it up now

Just ordered the book. Hope to have it before the weekend.  Headed to the track this coming Friday evening for test and tune.

Holy crap is your car sitting on jack stands?!  Or do you plan on taking it muddin'? 

That thing needs moar low.
