I want to take my car into the 12's and so I guess I should ditch the cast exaust manifolds. So why do you guys like the Supercomps and what else works well? Also do you tune them with collector length?
Thanks,
Dave

Alex,
I'm using my heavy '70 ragtop, 351W, 10:1 CR Windsor JR home ported with Vizard's book. 750 Holley VS. Comp Cam solid .569/.585 (minus lash), 239/247 at .050. LS 110. Also I'll be gearing for about 6k in third at the 1/4 finish line.

Hooker super comp # 6116 are the ones that you need Dave. A set of #11230 collector extensions should be used in conjunction adjusted to the proper length. ------------------

Sorry to jump in, but is there an easy way of determining collecter length other then testing different lenghts and comparing et slips? Seems like I've heard something about using cheap paint or a crayon line on the collecter to figure out the length, or is that for a crossover tube location?

There will be a burn ring in side the collector extension that will show a definate color change where the collector should be cut off when the tune up is correct. ------------------

Thanks Alex! How much et improvment can be expected with the proper length extensions over just open headers?

My car without the collector extensions is not quite a tenth slower in the 1/8. And it loses most of it in the 60'. I took them off one weekend two years when the track was real greasey trying to kill some bottom end torque, it worked.

Cool!!! I still got my 3in. pipes from when I had mufflers on the car, that was before the driveshaft broke and destroyed the mufflers. I'll have to throw them on and try it, have often wondered if extensions would help, but didn't know if it was worth the trouble to experiment with the lengths! Price is definatlly worth it! Thanks

That's the crossover tube Roger. The way I find the collector length is exactly the way Alex describes with the ring. On the crossover pipe.....
Crossover pipes don't work unless you find the "spot" where they should be. This is how to find the spot. Paint the mid pipe between the headers and the mufflers,a straight line fairly wide from front to back will work. Then start car while the paint is still tacky not too wet and be careful, it will possibly flame(depends on paint)so have an extinguisher handy. The part of the painted line that bubbles or deteriorates first is where the crossover should be. Don't be shocked if it's not straight across. Just put the pipe straight across from point to point if straight or in the middle of the 2 points if catty-cornered. If done correctly you should gain approx. 10ft lbs torque in the mid rpms. Hope this helps.------------------

Is the 'burn-ring' an easy thing to see? What are typical collector extension lengths?

Hi Jerry! I don't get online much at all anymore and normally when I do it is only a few minutes just to check my e-mail. Free time is so hard to come by these days it seems. Hope all is well in your camp.Dave,
There will be no doubt in your mind where the burn rings are, no sweat. As far as typical collector lengths...well, I don't put alot of effort into generalizing that so I wouldn't be much help there. I treat every combination differently, kind of like it was the first time you ever....well, nevermind.  ------------------
