I just bought a 1" 4 hole composite plastic super sucker and it says for race use only. Why do you think this is? Do you think it would be ok on a car that gets driven about 600 -1000 miles in the good wheather ? This is a car that will get driven to local shows and such and raced as much as possible. Anyone run one of these and how do you like it if so? Any help would be appreciated.

Keep an eye on it...it's probably just to cover their backs for warranty issues.
There's plenty of plastic on new cars that run much hotter than the old stuff.

I think for the amount of driving it will be fine eddie. If you don't like it I'll buy it from you.

There is the possibility of warpage, and the composite does not insulate from or dissapate heat as the others mentioned...mostly, I believe, the performance advantages of the spacer are not really realized until the higher RPMs.

If you look, 90% of the parts we put on our projects are listed "For race use only" or "Not intended for highway use". It's generally because they aren't meant for SMOG reduction, OEM replacement or C.A.R.B. certified replacement parts.

I personally wouldn't worry about it. But if you don't like the plastic, you can get the same exact spacer carved out of aluminum.:yes:

I run this one by proform. I don't know if it's the exact same material but It works fine so far on the street.

Also, last time at the track I was playing with the jetting and was amazed at how cool the carb was staying even when the engine was hot.

I tried the 4 hole tapered, which looks like the HVH, and the open spacer. The open seemed to work best for my combo which surprised me a little.

I've even read about people saying the super sucker worked best for them upside down. I didn't try that though.

Let us know how yours works out.

I got a really good deal on the composite one that is why I bought it. The aluminum one dont say anything about "race use only" just the composite one! I guess I will keep an eye on it to make sure it dont warp or anything funny like that!

Eddie, I'm using an HVH on my race car. I have heard that the plastic ones can melt and have even heard of this on some drag cars. I have never had an issue with mine though.

I'd just keep an eye on it.
