need advice

[powerfuldodge]

I have mySilber kit installed its on a 2012 800 switchback at 1000ft...I have the low boost spring installed , the boost controller turned down as low as possible and running 94 oct. fuel. Bottom end is fine but as soon as I get arounf 1/2 throttle the DET sensor goes off.. I did the 30 sec. data log on the speedo and im not over reving it only getting to 7200RPM...Just wondering what else I can try, or do to get the DET sensor to stop coming on.

Thank
ian D

Did you shave the air intake bolt as to not hit the jack shaft mount

it's shaved down as much as it can be , I probably removed 2/3 of the bolts head

I'd start by running 100% aviation fuel or maybe 110 or something. I'm assuming ur not running enuff octane for your elevation unless u have a timing key or ur running like two pounds of boost. I could be wrong but it's my 2 cents

Not sure what I'm running for boost but the guage that came in the kit doesn't really move that much. I don't want to run avgas,,,thats the only reason I got this kit is because with the low compression head I should be able to run 3psi on pump gas . I tried going out to the air port today to get avgas but the shall and esso station wouldn't sell it to me . I'll go back out on Tuesday theres a few helicopter places that will be open.

I had to remove some of the material on the jackshaft mount to keep the shaved bolt from causing some poor running issues. Runs great now.

You'll see marks from the bolt hitting on the bulkhead if that's the issue. Mine did the same thing. I couldn't see it hitting the rev limiter on the playback. Though I was over boosting for my fuel, but I ground that bolt head a bit and added a couple grams. No more det light. That's with straight av, 8 lbs, low comp head, and sea level.

I screwed up when I went and changed the low PSI spring I actually put it on the BOV instead of the waste gate ...so I have it all straightened away but it to late to take it for a rip..so be better now.

Thar's exactly what I had happening. Once I shaved some of the bulkhead away she turned into an animal.
