If you can light the tires at will with the TCP rear when you're driving, your hole-shots are most likely gonna suck horribly, at least with street tires. If you ever drag race at the strip, one thing you realise very quickly, is that in order to get a good run, you need to stick a lot of power right outta the hole. That TCP setup I'm sure will make the car handle like you never thought it could, and it's not that dis-similar to setups you see on some road race cars, but it's not designed for drag racing. How much power do you have now that you can light the tires at will with?

 

I'm sure with the right launch there is a great chance of running a respectable lap. If you've got your foot on the brakes or you drop the clutch (if applicable), I'm sure you could light them up on demand with stock V8 HP.

 

The dyno sheet says 527 RWHP at 5645 rpm, and max torque of 513 at 4964 rpm. Here's a snap of the monster lurking under the hood. I've never run the quarter, more into the road race stuff. I would hate the idea of nuking my new TKO 600 doing hole shots...maybe it would handle it?

Well, I notice you have a centrifugal s/c, which will help with your setup a lot at the strip and on the street, since it keeps the torque from being insane at lower rpms when you launch. I also like the intake Actual GT-40? Those are hard to come by these days, and work really well. As long as you hook up road racing you shouldn't have any problems if that's what you're in to, drag racing though, may be hard to pull good 60' with that kinda power and the rear suspension. As far as the TKO 600, the only way you'll hurt it drag racing is with a sticky tire that hooks with clutch dumps, it'll shock load the tranny but they're still pretty freakin beefy. On street tires you'd never be able to get enough traction to load that trans up enough to hurt it unless you drive like a goober. You may be able to get an ok launch at the strip, but it may be like the IRS Mustang Cobras, spinning every time you shift, unless you go easy but that will slow your et's down. Won't really know until you go to the track. You could always go to a taller gear, like a 3.00 or a 3.25, with wide enough tires you could control wheel spin that way, and it may not be too bad for a road course either. Another option(which is kinda sucky since you already spent the money on that rear) is swap out the rear end you have for a 9" quick change. It'll require some fabbing to make it work with the TCP setup you have, but you can then basically change out gear ratios real quick for road course, drag strip or street use. It'd really let you tune it for whatever you do with it, and you should be able to control wheel spin that way.

 

I'm running a Ford 9" with 3:89's, posi with Moser 31 spline hardened axles. It seems to go around corners very, very nicely.

 

Yeah, 3.89's with power will have a tendancy to spin tires, especially street tires. If the wheel spin is too much, you could try stepping down to a 3.40 or even a 3.25. From the rpm you make power at, it would seem you're not struggling for bottom end torque so taller gears won't make it drive like crap, and even with taller gears you still have plenty of power so it'll move. See how it does from a dead stop or a roll. If you can spin the tires too easily then a taller gear would prolly be better. Putting more power to the wheels with a lower gear is useless if you don't have the traction to actually put the power from the tires to the ground

 

That's probably some good advice. With 527 rwhp, what do you suppose I am losing in the driveline, or what would be your estimate of crank HP?

 

Typically the general rule of thumb is about a 15% loss for a manual and a 20% loss for an automatic. Your crank hp is prolly a bit north of 600. If that's a stock 302 block, I hope you have it well tuned

 

A friend of mine has a 90 GT 5.0, stock block worked to the tune of 638 RWHP. I'm sure Zuluracerx's set up will handle the power he's making.

As far as the torque, you need more torque during launch to get that monster rolling on it's way down the track. Why do you think trucks usually have higher torque at lower revs? To get the payload rolling.I'd rather have bucket loads of torque on the bottom andendless HP at the top. It works out better.



Feel free to correct me if I'm wrong.
