What blows stock head gaskets?

With my BDP stage 1's and non-BB TN I can now bury the needle on my 35psi gauage in the 80 econo file......so who knows the #'s might be higher.

Ive heard/read drive pressure is almost double that in some applications. So my question is are my head gaskets at risk. I hardly ever drive my truck that hard. How I actually found this out is when John was test driving my truck to dial in the valve body. He floored it from a dead stop, and by the time we were at 50mph or so the boost needle was buried.

If it helps any my boost sender is tapped in on the compressor side.

Re: What blows stock head gaskets?

Cylinder head pressure will blow head gaskets. From what I understand they are good to 45 to 50 lbs.

Of course, I was assuming when he said stock head gaskets that he meant stock bolts also. But you are right we should never assume.

IMO i wouldnt go much above 40 if you want reliability. However if you have studs, i would have the confidence to push 55+

If I were you, I would have the 1.0 housing on that turbo.

I have that housing too in the garage, but I dont want to deal with the lag. John even told me that for what I use the truck for I wouldnt like that housing either. I know that housing will help lower drive pressures. Does that inturn relieve some pressure on the head gasakets?

Re: What blows stock head gaskets?

With stock head bolts 38-40psi is about all you want. Studs are good for around 55psi, so I have been told. I beat the heck out of my truck with 53-54psi and all is good, for now.

I would think so. Look at the BOOM thread. Poke here
