100hp / Liter

Jordo! · 10-19-2011, 04:29 AM

On the average, about 307-310 to the tire on a dynojet should be in that ball park at the crank, but really short of removing the motor and placing on an engine dyno, it's an educated guess at best.

On a dynojet, full bolt-ons' plus tune will get you in that ball park, give or take transient factors like intake temps and correction factor. You may exceed it with pulleys (IMO, not recommended) and long tube headers (big job).

Other kinds of dynamometers typically have numerous settings that can be adjusted, so depending on how they are calibrated, it's hard to say. Dynojets are generally very, very consistent from one to the other, where correction factor is only major X factor.

But really, that specific output per liter isn't anything special. You can build N/A motors that will exceed it, and with forced induction go well beyond it.

My two local dyno's are a MAHA and a Dyna-Pack

TBH I dont really care what the headline number is so long as its 40hp above the base line - job done

Pick one, get a baseline, work out the change from the claimed 332 bhp, add bolt-on's and see what you gain

Is MAHA a rolling road? Never heard of it.
