Turbo/fuel question

[SJYAMAHA]

Running 2011 Nytro with 180 Push Turbo kit at 8-9 psi with supreme gas wondering if any advantage mixing gas with VP C12 or am I just wasting money, I don't mind buying the C12 if it is going to help with life of the motor. How is too much boost on stock motor(aprox 1200 miles on motor)
Any input would be great.
Thks

i have a push turbo running the same boost. never had a problem with 8-9 psi running good 93 octane. a friend of mine has a push nytro and he runs 7 psi (93 oct) wide open across an entire lake with no worries

If your engine is decompressed with a head shim then you'll be fine at any elevation. I won't go a decimal over 6 with a stock nytro unless you're riding at 7000 ft or beyond. Based on the boostcalculator, for the nytro with stock motor (no decompression at 9 psi) here is the octane per elevation
0 ft = 98 octane ~ 210 hp
5000 ft = 93.5 ~ 188.3 hp
7500 ft = 92.4 ~ 178.6 hp
10000 ft = 91.4 ~ 169 hp

Hopefully this helps.
