Rb25Det How Safe Are Internals?

[500hp]

Ah ok I never new how much octane is e85

You gain nothing from running w/m on top of e85. Tried and tested. Either run one or the other. E85 is slightly better than water methanol though.

Is this proven that e85 is better ?

[GTSBoy]

Massively better. If for no other reason than you don't have to have a separate tank, pump, controller, worry about WM running out, etc etc etc.

The problem with water methanol is that it is a parasitic loss in the engine. You spray a lot of water in because that's where the cooling comes from, but it isn't fuel and it has to be heated up to exhaust temperature. That's an energy cost. The cooling in E85 is from a large chunk of alcohol, which both offers good cooling and is also a fuel. So there is a much smaller parasitic load along for the ride (there is a little compared to straight petrol in that there is more water in the exhaust gases of alcohol, which does have to be heated to exhaust temperature, but the effect is not as bad as with WMI).

on a R33 motor right? don't the ringlands let go? I know R34 RB25DET NEOs are built as well as tanks

yeah, ringlands are fine provided the tune and engine it self is sound, one engine made high 400's but my testicles were far to small and we stopped pushing.

[Joshbigt62r]

Trent and how long has that engine been pushing that power for now? That's a fair effort.

Cheers Josh
