Mechanic for my 2007 Revolt turbo

Looking for a mechanic in the Phoenix area that can repair my Revolt.
Randy Jungwirth from Weberpower, Inc. said to give the forum a try.
Anyone out their. The problem is probably in the crank bearing and maybe top end. Haven't ran compression tests or pulled the oil filter yet but it does crank over slow and seems to be firing on only one cylinder.
Recently purchased it from a guy up in Colorado Springs that said it was all dialed in. Guess it couldn't handle the 14 lbs of boost going up Oldsmobile in Glamis.

14lbs of boost is no worry for the weber. Probably sand ingestion.

You need to do some testing to find the problem. If it is a major problem you maybe better off pulling the engine and sending it to get repaired. Thats if you can not find someone that is close to you.
Sandracer is right on, 14 psi of boost is nothing.

Re: Mechanic for my 2007 Revolt turbo

Thanks for the info guys.
Getting it tested for cause is at the top of my list. No repeats please.
Don't think sand ingestion was the issue. I only ran from wash 6 to Oldsmobile Hill (about 2 miles) without following anyone and it is fully sealed with outer wear. It happened when I gunned it up the hill WOT.
Think I shot myself in the foot as the gas in the tank was 6 months old and I just threw 91 octane in for the fill up of 50/50 old to new. Not igniting properly in the chamber.
Going to make a few calls in town today as most shops are closed on Monday.
Do you guys run 91 octane or what?

Most everybody runs pump 91 octane as long as you have the 9 to 1 compression turbo pistons in it that would be safe. 15 lbs boost is also safe with the turbo pistons also. The problem might be the injectors. If the previous Colorado owner put in smaller injectors for running at the higher altitude you may have leaned out too much. What color are the injectors? The FST injectors that we use here in Oregon are black. That is what I would say you should have in yours. If they are orange or yellow they have been changed from the FST set up. What did your air fuel ratio gauge read while at full throttle under a load? If it was higher than 11.8 it was too lean.

Pilot,
I currently have the Revolt in the shop and will be torn down on Friday and Monday. Still collecting data and educating myself on this motor and setup. It does not have an AF gauge but will be installed before future rides.
I will check on the injector color and get back with that and the cause of failure.
Thanks for the info.
