Great numbers.

 

Thanks guys.
Ted B always right on point.

 

She got headgame man...LOL

 

What would be the effects of sustained high EGT's?

If you are det free, I can only see a problem with turbo. And if you look at the reliability of turbos in comparison to engines, I don't think I would have much concern of the turbo.

Again I am just total amatuer but just curious.

 

High EGT's=Blown turbos and melted valves.

 

So where do you think all that heat goes? Does it all go out the exhaust, or does some of it get transferred to pistons and valves and such?

 

Yes but if your det free presumably the exhaust valve temps are in check? I dunno.

I hate to have cluttered up DTM's thread. I was just curious as to how he went about choosing the boost level. And if actually he simply did not make anymore power with more boost. Seems hard to imagine because Buschur motors are 9:1 I think and run 30 psi on 93. While 9.6:1 is not a big jump from there.

 

Actually 9.6:1 and 9:1 is a pretty big difference in static compression, even bigger when you are force feeding it with a huge turbo. I'm sure Nick could have made an extreme amount of power by turning up the boost, but it a TA car. It's meant to run at WOT alot of the time. Its called risk vs. reward.

 

When pistons and valves and such are exposed to excessive heat, they begin to absorb that heat, and will do so until the metal surfaces reach the same temp. When this happens, the resulting hotspots will increase preignition potential. When the fuel mixture begins autoigniting, you're done.

There are differences of engineering strategies between endurance racing and drag racing. The motors running 30 psi on 93 octane aren't being subjected to 30 min of WOT events.

 

Once again, Ted B puts what I am trying to say in a post alot better than me. Thanks

 

I can safely say that he puts things into words alot better than the majority of us.

 

I hear ya guys and thanks I understand what your saying.

 

we could spice this conversation up with some valve seat, valve guide and valve material conversation now that we are talking about heat if everyone is down with it.

 

YEs please!!! Inconel? Do tell, whatever your willing to disclose, I am sure porting an OEM head is a good bit science and a little bit art but I would love to learn more!

HeadGames, lots of people and or vendors on here have been selling your machined heads as there own, do you yourself offer the services or just through vendors?

Given that the originator of the discussion mentioned the use of your head specifically, and being that this is relevant to the discussion, I feel it's totally appropriate.
