any news from your dad, has gone to any of the races yet?

550cc is really a bit too big

i know taz but they where free and don't forget I'm using E85 30-50% more fuel usage

yeah rob nurburg 24hr just started and they came 1st in class in the spa gp 12 hr

did u see this post http://www.rollaclub.com/board/topic/52549-eoi-supercharged-5k-ke30-3500/page__pid__535273#entry535273

yeah its pretty mad

hey guys how much boost untill i wreck my sc14? i need it to go fast at winton so ill keep boosting till something shits on the dyno then take 2 psi out lol so ill stop at 20psi if it handles it it will stay at it :) also i have E85 not normal ulp E85 is pretty much methanol

More about the speed your spinning them at that matters. i think they're safe up until 12-14,000rpm lobe speed untill the teflon coating begins to seperate.

so i can spin at 2:1 and get like 30+ psi haha

to get 15psi according to my calcs it will be underdriven i had the percentage in my head all gone now and 20psi slight over and at say 7000rpm it will be doing around 8000rpm

As long as your SC exhaust temp isnt hot enough to melt the coating. These chargers are known for having low thermal efficiency compared to other charger types (screw etc)

so is the sc14 or the sc12 better i went the 14 so it will spin slower and create less temp theoreticaly well thats in my head haha

wonder what temp they melt i could have a temp sensor on the boost side and have the motec operate a charger over temp warning on my dash

For my 4K. to get 7-8 psi on a 4K with SC12 it was a 79% underdrive.

i think 1:1 with sc14 was around 15-18psi from what i worked out but i havent tested so really I'm only guessing till i see what it has
