[135i2]

A 3076 is a long, long way behind a 3584RS.

It looks like the 84RS will do high 500's plus with a strong enough engine and appropriate fuelling.
I will test a 3076 or 3576 down the track and we will know with hard data, but close to the 3584, no.
Do I think we could hit 450rwkw on a 3076R with my current mods? Possibly, probably. Will I try, no! My fuelling will be upgraded for any further dyno runs.

My stage 2 lpfp wasn't enough to feed 350rwkw plus on 98 with twins to make constant power, so a reasonably sized single with just a slightly upgraded lpfp on e85...nah.

Everything depends on power targets and what you want from your car. You might get away with shooting for a high number briefly on the dyno without proper fuelling but you wont achieve reliable, constant, big power.

At 25psi plus on the dyno, I need larger PI injectors, dual shotgun and upgraded lpfp from stage 3.5 to stage 4 or better.
On the street a single shotgun and PI are just starting to max out at higher RPM on my car. Not ideal.
