How long have you run the whipples on the 500efis?

They were installed at + - 20 hours and I had one melt down (lost a bearing) with 45 hours of use. Whipple replaced it for no charge and did a recon of the 2nd. one for a fair price.
At 175 hours I had a bearing start to go but I caught it in time and Whipple again did a recon on that one.
The Whipples have been a bit of a pain but the 500's have held up well. 185 hours total time now and going fine.
When I had the complete failure we had to tear down the engine to look for loose metal from the screws contacting so at the same time we pulled both motors and rebuilt using thicker top pistons which are supposed to handle the cylinder head temps a little better.

Keep up the good work, are you running extension boxes ?
Does this application work on 92 octane fuel ?

We usually run on European 95 (RON) which is comparable to
90 Octane US Fuel (RON - MON / 2)
RON = Research Octane Number

89 Octane US will be fine
the stock 600 now runs on 87
