At what point does too much hp become a problem? I'm going to build my first T (prefer a 23) and I want to do it right the first time. I want a 520ciBBF,tunnel ram 2 4brls, wicked hyd roller cam, 700r4 trani, with 410gears, and alota tire on the rear... so please help me out guys, what does it take ta get 550/700hp to hook. What kinda problems am I in for at 65/70mph and drop it back a gear...Does it get loose, or just fly. Do ya have your frame mounts back an inch or to for weight transfer (for the holeshot). Do ya run a 4link, like one set-up in a prostreet car/truck. I app. any and all info from you guys, and yes I'm starting from scratch, and want this beast to be rolln in approx 3yrs. Ty 4 your time:)

I run a small block Chevy with a 6-71 blower. I have not had it on a dyno, but desk top dyno says 650hp. It won't hook like some of the drag cars I have had. Here is a pic of the back end. I think a lot of the problem in getting a bucket to hook is the front end won't rise and get any weight transfer. This car has a 4:10 Dana 60, with posi and 20" wide racing tires, a Moroso 4 link and while it does OK it just does not hook like a car with drag slicks on it.

Thanks 4 info, and your T looks great also. I'm not totally interested in getn it ta hook off the line, I'm more concerned in how the T will handle when ya drop the hammer at 65/70mph. How does yours run??? Are ya rollin on 100+ b4 you know it? If it's not too much ta ask, do you have any pic. of your 4link set-up, and what brand tires are those on the rear. And thanks once again 4 info.

This is what I used. I just bought the plates then made the links myself. Note that the rear kick up is 90 degrees and not like most chassis at a 45 deg angle. Yea 0-100 is real quick, I have had it over 100 several times and it handles fine. The tires are Firestone dirt track tires for the right rear of a sprint car.

I have a stroker SBF that makes 515 hspr with polyester white walls and it does 0-60 in about 3 seconds and by 4.5-5 seconds I am blowing past 85 mph. This is with the tires spinning so I couldn't imagine 700 hspr. These cars are so light that they just take off even when they are spinning.
