WOP Fire Rings

Powersmoker · May 13, 2012

Anyone running more than 80 PSI with only fire ring grooves machined in the heads?

Does boost actually seem to gauge well for its ratio to CP? The real issue is CP level which looking at TQ would likely be a closer estimation. But I have wondered if in general boost seems to track well with it given nothing extreme in ratio of boost to BP. I have wondered about this as the actual boost level in and of itself is a minor addition to pressure, but its results with fuel on CP is another story. So, I wondered if boost tracked fairly well with CP?

Hows it run Brian? I see you're taking it easy on it breaking it in, 80psi.

How much valve spring pressure are you running?

Yes.

180 if I remember right... The valve springs are pretty big, required me to grind the injector hold down brackets. Same heads I ran on my last built engine. (Buddy VanAcken's old engine)

Haven't run it long, did a hot retorque this morning then had to leave the shop. I will be dialing the gates in tomorrow.

No puking at 1000hp?

Lightning runs around 115-psi boost with only the heads cut, never had an issue. As long as the machining and hot retorque are done correctly you should be safe.

Awesome

My old engine had grooves cut in the block and heads. Couldn't find a machine shop local willing to do the new block this go-around, so I had them re-cut the grooves deeper in the heads.

Have not hit 80psi yet, but been around 70psi a few times. 15k later... so far so good.

Powersmoker · May 13, 2012

Looks like I'll be cranking the boost up then LOL

My goal is to run tens on fuel, we shall see.

907DAVE · May 13, 2012

Good luck!

We'll be watching!!!

I have a built motor I took out of a race truck for my back up. It has WOP firerings with only grooves in the heads cut by BTS. Truck wasnt running 80psi, but 60 or so. It was also a street truck has around 16K miles on the motor with no issues I could see when I pulled it.

Just trying to give you some more confidence. Give it hell. :ford:

Great post I was curious about this. Since nobody in my area will cut these grooves, and don't really want to machine the bottom in for the WOP girdle.
