Exactly! Most people know when they've pushed the engine too far.

I am not saying it is not possible to run an engine to that high of a temp and have it survive. I am just saying that it is not good practice.

And if an engine needs to be that hot to run properly then it has some serious design flaws, or more likely the pipe is out of tune until the ex gas temp comes up. Id try different pipes on the suspect engine.

And as I was saying, I haven't used a temp gun to tune for many years now. Does that mean I'm cool and can have an engine named after me?!?
JK!

I've won quite a number of races with my CRF "screaming" at 300F.

Well, now that you mention it, I was wondering how long it would take before the idea crossed your mind. All you have to do is partner up with an engine manufacturer. I would definitely buy and engine you designed!

Sounds like some new burger from burger king

I never use temp guns either. Dont even own one yet. Way I see it, we were tuning race engines long before temp guns came out. What changed since then?

I run my JP FX21 RO3 at 220-240f for 5min quals and no more than 220 for a 15-20 min main with plenty of power. if you have to run 300f just to get the power you need? well maybe. just maybe you have a wrong kind of engine. you are just too fast for that engine...

btw : this guys do not use off the shelves engines like you and me.

I agree with tuning for performance and using the temp gun to make sure that you are within a reasonable temp range.
