Anyone have any experience with the aftermarket "Precision Power" intake manifold gaskets. I purchased one off ebay. Supposedly better insulates manifold, cooler intake temps, more power, etc. etc. I was about to install it but appears to be thicker than oem gasket not allowing any crush on the coolant jacket O-rings. I am tempted to just install 20mm frost plugs as I am going with a racing beat 4bbl intake. Just curious if anone has any experience good or bad with these gaskets.

 

Never heard of them, and by them cooling the intake temps... I doubt it unless you can find a thermometer that measures to the thousandths. Stock is IMO the best, and if you want to keep it cool, make a heat shield. That is a very noticable difference. When the car is running, I can put my hand on the bottom of the intake and not get burned.

 

Sounds like a scam to me. How can a gasket cool intake tempetures to a noticable amount..??

IMO stick with stock gaskets all around. They were made by engineers for that purpose only. Just my .02

 

Someone else asked about these gaskets a while back, never heard back from them. While the idea is good for direct injection FI fuel systems, it doesn't really help us carb guys out. With my own home made intake gaskets and the coolant ports blocked off, both the Mikuni and DCD intakes can form ice on the outside, sitting there idling in the shop in the summer.

I can't see that big of a benefit from them and if the o-rings don't seal, then they're worthless for those that don't install plugs.

 

A gasket is a gasket. It seals or it doesnt.

Freeze plugs are almost a must with the RB intake b/c the manifold blocks the lines off which creates pressure that is hard to with-hold with just O-rings.

I just used a 1/2in peice of a broom handle widdled to fit and about 2 lbs of hi-temp RTV over that and have not seen a leak since.

You are probably thinking "ghetto," but it makes sence b/c if you think about it....what does wood do when it gets wet?? It expands.

 

^^ A broom handle? I like the fact that you sai "widdle", reminds me of my dad.

 

haha.

My dad is the one who widdled it for me!!

Dads are all the same.....

But seriously, it does work.

 

For now. The coolant will eat the wood away. If you used the stock intake gasket with the Racing Beat intake, then you use the rubber o-rings with it. I don't know where you got the impression that the o-rings will not hold. The coolant jacket in the block flows by the intake. The coolant system with the proper radiator cap should not be more than 13 pounds of pressure. The e-bay gaskets are a joke. You can get the stock gasket set a Advance for about 12 bucks. They never have them in stock, but can get them in a couple of days.
