Help me reach 600whp on upgraded twins without E85.

this isn't entirely true. Boost pressure as well as timing need octane equally. Both increase cylinder pressures and create heat to an extent, both of which require octane to keep pre-ignition and detonation away.

That's understandable, but wouldnit be safer "generally speaking" to run more boost with a conservative amount of timing, rather than lower boost and higher timing? I would think the inconsistency in fuel quality would have things skew to the lower timing being 'better'. Granted, if running ethanol, this discussion changes dramatically.

Great to see you active @Twisted Tuning

always bud. Just sometimes don't have the time to check all the media platforms and deal with the day to day.

neither is really safer than the other. Too little timing can cause issues as well. So compound that with high boost. and its no safer than low boost with high timing. both can create great amounts of heat and an environment for detonation or pre-ignition.

Well you guys win. I contacted the shop and made the switch to docrace 6266 ball bearing. So what am I looking at now ? do I still spray a lot of meth ?

Whoa. Great choice

A 6466 should make about 600whp on 93 iirc. A 6266 a bit less...really will depend on your tune...I would run some cp meth and tune it on 93 and see what you end up with. My guess is north of 600whp depending on how much meth you run and how aggressive the tune is. If you want to hit 700whp you have to go direct port.

Have fun!

Thanks! I was hoping to have a few different maps for different power level... I guess JB4+backend will do that for me. Basically 400,500,600 whp maps + race gas map.
