Hey Art, in your class are you allowed coatings ?

Ive got some waterbased ceramic that is a heat dissapation coating, stuff works great. Ive got about a half gallon of the goo left, coating the intake inside and out I can almost guarentee a big heat soak drop......problem is once it does the stuff works the other way around and will hold it in, but it takes a lot longer ? Why kill the water passage ?

Hi Chris

Yes I'm allowed to do anything I want to the manifold. But In the not to distant future I'll be going to a 4 throttlebody setup (that was really what I wanted the spacer for). So I'm not going to waste a lot of time on my stock type intake.

Gotcha, hey Art on that note, if youre going to have them made how about outta a thermoplastic ? Or do any of the OE setups come that way ? Just a thought....

Timing light is in the trailer. I'll go get it on Tuesday and double check it but it starts easy and idles great.
As far as reversion goes. This is a different cam (much bigger) than last year. I haven't paid attention to the manifold heat this year. Each time out I've been heating the engine, to allow heat soaking. I'm finally going to a track without eyes. So I want to know what I can pick up with a cold intake.
Took a leakdown to see if I had some bent intake valves It was 3 to 5 percent (not bad for gasported pistons).
This is the motor that I had asked about the compression pressure before It is 300 pounds. I worried myself sick about it. But have just learned to live with it as a quirk with the 4 valve setup.

Art, I do not think your timing is off and if you have a reversion problem, it not not create heat. You need an isolator made of thicker material such as phenolic, Black Nylon 66 or similar high temperature thermoplastic. I have not seen your intake location, however, is the intake above the exhaust?

Re: Intake manifold heat?

It is in front of the motor the header is in the rear. checked timing it is right where it's supposed to be.
I might just leave the spacer in and got to Valdosta the way it is. then try to compare intake temps to comparable ambient temerature.

This is the manifold style of the future for me with 4 individual throttle bodies.
Total cost $1200
The present one is made from a dodge caravan base (the runners would be legal in stock LOL) with a box welded to it.
Total cost $200.

Overall. I'm very pleased by what I get out of the car compared to what I have in it

My first thought was "why would he run a muffler up there...:rolleyes: "

Don't know about mufflers, but I have a front mounted parachute
