Im only getting 5000 rpm with the 23 pitch mirage, im wondering if im loosing rpm somewhere.
Carb is a 750 holly maybe there?

What rpm's were you seeing before she grenaded and which size prop?

I just put in new dist so im getting the 34 degrees

It was only turning 4500 with a 25 Mirage prop and I know the motor turned 5300 easily on the Dyno which is why we started checking items and found the timing to be to high. We think the timing was not allowing it to turn up properly and unfortunately we found the issue to late. I'm running a 850 carb on mine.

Ive never ran on a dyno but you dont have the friction of turning a prop..
I should be seeing my mirage 23 plus any day now, ive read about engine blowing up too from too big of props, you think the 4500 wot seems a little low...

The 23 plus is probably gonna bring your RPM's down over that 23 standard Mirage you got from me, if you want to try my 21 plus, just let me know, probably gonna be out on the water somewhere July 4'th weekend.

The dyno uses water to simulate the pressure. Most people with lower hp than me are running 25 mirages on the Pythons so I don't think my prop was to big.

Alirght no prob, rchevelle he was saying he was running 4500 rpm with the his prop, im turning 4950 with prop you sold me, so i dont mind if i loose a little rpm and gain some top end with 23plus, i may even look to try a 25 3 blade
