I Have a 302 thats stroked to a 347 and im planning on using my paxton supercharger to run around 5-8psi of boost and I was wondering if I needed a stronger intake manifold gasket over a oem one?
thanks

Nope, just make sure the intake is torqued down properly or it can lift under boost

On alum heads I use 20ftlbs, iron 24ftlbs and on boost applications I use a tiny bit of liquid teflon to help them from loosening up.

That is correct!

However, I am running these new VTS Heat Shield Gaskets on my Cobra and Lightning that virtually eliminated the heat soak to my new intercoolers. I think if you were able to lower the overall intake upper plenum and lower intake temperature by just using gaskets I think that it might give you a little more power by letting you add a little more timing.

Back in the day I know that they at least made a gasket for the upper and lower intake joint and I was running one on my 67mm turbo GT. It helped quite a bit with keeping my IAT's from increasing due to the heat soak of the upper intake from the high under hood temps of a turbo 302 not to mention the heat it was absorbing from the lower intake.

I dont know if they make them anymore as I didn't see them on their website but I am sure if you asked them and you had a few others that wanted a set that they would make them for you guys. That is what happened with my lightning anyway. I think they told me that I needed something like 5-10 people or 5-10 sets and they would make them. It has been a long time so I dont totally remember. It is at the very least worth looking into.

I will try to find the testing chart that I looked at before I got them to make the Lightning ones but no promises!

Here is their site link, I will try to round up their phone number from my receipts file of the mods on my car and truck, but again no promises.

VTS Racing

I think there is on of the Gasket performance charts here:

Velocity Turbo Systems, LLC

I will try to find the Big one that I looked at before and I will post it with the phone number when I find it.

Good luck and have fun! (watch for cops! lol)
