Just seeing wat everyone else thinks! Who have done it and how long did it last? Etc I was thinking for a race tune, doesn't have to be 450 just a thought. I got all supporting mods besides rods and pistons which is in the future list I have bf Fpv mk 2 f6 bottom end with 6000kms on it at 390 kws pump fuel. I was thinking to moving to e85 or av gas

U high?

Its not a good idea. It may last awhile, it may last 20 minutes.

A set of rods at least would be a good idea.

its all in the tune mate. I dont think tuning it with a different fuel is gonna hurt, as long as you dont go nuts on timing, and keep a safe afr ratio...

e85 is the way to go...

go for it!

Yes it's been done, forum member Glouva 1 FG, runs 457 RWKS from memory on E85. Look in the 400+ section.

Glouva is running full stock xr6t bottom end. You have an fpv bottom end so it may be a bit better/safer

Whats the difference with the bottom ends?

FG xr6 bottom end = BF F6 bottom end bar dip stick and sump.

Ah k. What's the difference then between FG XR6 bottom end and FPV's FG version?

lower comp pistons I think
