Don’t even think about
removing that turbo. You keep thinking in terms of boost, but you should
be thinking in terms of h.p. (and RPM) What I mean is that I have never
heard of a 13b blowing itself up that was producing less than 250 hp. Let alone
less than 200. If you are not making the h.p., then you are not stressing
the engine.
I agree with this
logic.
Same argument goes for
normalizing. So what if it takes 11 psi of boost at altitude?
This "may" be
fine for the engine, but it could be pushing the stock turbo pretty
hard. Guys run these things on the street at higher levels, but that's for
maybe 15 seconds at a time. Sure wish I had a compressor map for the stock
turbo.
What do you have to
loose. Worst case, its really not that hard to re build an engine
(compared to re-doing the intake and exhaust systems).
Of course if you're turbo
system blows the engine, you won't run it that way again, so you'll be
re-doing the intake, exhaust AND rebuilding an engine :-) I can
pretty much say that the rotary has a one engine chance of success. If
it blows, I'll be shopping for a
Lycoming.
I'm going to try to go to
the airport this afternoon, and stuff a thermocouple inside the hose from
the turbo to the intake. I want to tie the plane down, and run
the engine at various boost settings, to see what the intake
temp is. Hopefully, it won't be too high, but we'll see. As
I've stated a few times already, there's no way I'm installing an
intercooler. There's just no available space, or weight for
it. As long as the temps don't seem dangerously high at 5 psi, I'll
fly it again this weekend, and see what it will do with a bit
more boost.
Cheers,
Rusty
