Seeing about 80-85 mph in Revy pow. That is of course once the sled is planing the snow...uphill though. I never run more than 18 lbs boost and usually around 15-16. Fuel is 50/50 C12/Prem with 9.5:1 in my Nytro and 10:1 in my Apex. Both have 2871 turbo's. We have made some changes to our Nytro motors this year so we can run up to around 25 lbs boost.
Maybe will see 100 mph track speeds???
