Rotax Racing IC - How to find leaks?
I think my boost is escaping somewhere. What's the best plan of action to hunt that down? Anyone else run into this?

How do you know that your losing boost? Do you have a BOV?

Just a guess really. RPMs are firm at 7650-7700 today in the heat. I get there is a hurry and then just top out. I am assuming that the boost is escaping, but not certain.

the more i think about it the more i think its the pitch on that solas.
jarrett, remember when i told you i ordered a new solas from Dave at Impros? Well, i was topped out at 7800 RPM's with that prop. It was pitched at a 14.5/20.

Jerry, I just looked at mine and it is a 14/20. Don't know what that means, but the stock prop is on and ready for a 6:00 a.m. test run tomorrow

Jerry, I wish that was it but in Riva Stage I form, I have run this same prop up to 7900-7950 in Texas heat. I hate to admit it, but at this point I am 300 RPM down after installing the Rotax Racing Stage I.

My problem, as it may be others, is that I put on more than one mod at a time and then when a change in performance for the better or worse is noticed I can't say for sure which alteration I did that caused it. The RR Stage I has many mods...the ECU is what sticks in my mind with the loss in RPM's based on a previous thread I read. Or perhaps you were the one Jarrett that had the dilemma with the RR ECU and was trying to work something out with Mark U.???
