Running a crate motor and looking to decrease under hood temps. Is using a wrap for the headers worth the money? reason I ask is because of our body the air cleaner doesn't make it out of the hood so its not drawing as much clean air as I'd like it to.
I have looked around and its going to cost about $100 to do both sides with a coating for the wrap after its on.
Get it thru the hood PERIOD! You are giving up a BUNCH of power even running 200 degree air temp. You are loosing about 1% HP every 10 degrees of air temp if I remember correctly. SO if you are at 100 degrees out side you are loosing about 40HP that you are just throwing away.Quote:

I have seen some of the super guys that come to the track have like a shield built under the carb that appears to keep under hood air away from the carb. Anyone have pictures or a how to on buildig something like it.
Exhaust wrap is a great idea, I wouldn't crate race without it, I seen a 5 degree underhood temp reduction with it
What your looking for is an air pan Allstar sells them around $75 i think
Wrap the headers and do the airbox ! BRC (lazer chassis) also has a nice one out of fiber glass. REM plastics also has one. PM me if you can't find one I think I have one or two. We built a custom one this year.
