Silber owners question.How much boost?
- Thread starter turbonium
- Start date
I run mine at 12 but have had it up to 15 a few times.
I'm about the same as Boston. I was having trouble getting more than nine until I found some potential boost leaks. First off make sure the castings of the throttle body outer bores where the o rings seat are filed smooth. Mine were in need of a massage. Then the alignment of the air box is at the same angle as the bodies. Mine needed a spacer on the top mount tab to true it up.

At what PSI is race fuel (or a mixture of) required? I run above 9k.

Personally I run a 50/50 mix of 91 and 110. I live in the same area you do and ride the same elevation as you. I'm at 10 psi. When is it required and how much RG is up to you. I don't cheap out on RG. I also haven't attempted to see how little RG I can get by with because it runs really well with a 50/50 mixture. I'm sure I could get by with less RG and try to tune it a little better, but I ask myself why risk it....
112/92 mixed 50/50 and ran 10 psi boost last season at 9k+ the year befor this I ran 8psi with av gas.
I ran 10-12#s at 0-2000ft on straight avgas... No det issues with a par 12.5:1 head.
Is the 91 ethanol fuel? Or have you spent the coin on non-ethanol? Thanks for the reply.

Ethanol
I've just been running 91 ethanol from the pump. I do the best I can at getting it from a station that goes through a lot of it in hopes I get it somewhat fresh. I've contemplated buying a drum of 88 non ethanol (only oct level I can find in drums right now) along with a drum of 110 and keep in my garage.
Ironically, last year I had one tank of terrible fuel that made sled run like crap....it was actually the non-eth fuel from Laramie, Wyo. Not saying it was the non-eth that made it run that way as I'm sure it was just crap fuel to begin with.

100LL 7 PSI Sea Level to 6K tops...
i was wondering if i could run 8 psi with the par 12.5 head at 1800-2000 ft on straight av gas ,and by the looks of things i can,you must have awesome bottom end with this set up ? i was worried about det issues but didnt want to do low comp and loose all my bottom end, my bro runs 10 psi on straight av 1800-2000 ft no issues 11 comp domes
Should rippp
