4.09

[Krilla5.0]

Will changing to 4.09 give me the best 30 to 130 times. N/a intake header e85 car with current 3.15 gear. Don’t plan on boosting and don’t care for top speed either. Just looking to maximize speed and acceleration for an n/a car from a low roll to 130

4.09 on the gen 3 is like 3.73 on the gen 2.

Are you auto?

Ten speed car

I haven't run any gear calculators but I think it will shift into an overdrive gear so you may end up having to install better clutches.

To answer your question, yes it will run much faster.

So what is the verdict Krilla5.0 ? Are you buying a set of 4.09 gears ?

There was this 4.09 thread a few down from this one… not sure if OP has seen it…
