It will run without an alternator for a short time if the battery is charged. But why do you want to?

It will run for a little while if the battery is fully charged. I've seen drag cars and bikes do it but it's a pain to keep charging it after each pass and you have to keep it turned off and push it till you are ready to make your pass. If thats what you were planning on doin with it of course. I cant see you doing anything else without one.

the racing i do is about 5-8 laps of a 400m oval. i'm hoping to not run an alternator as it will free up a little power, also the crank pully will then be made redundant.

Not quite. Still acts as a harmonic damper. Maybe fit a fluidampr? 30% underdrive for the alternator and no PS. For OEM you have the Euro-R (or was it ATR?) which has electric PS, so no PS area on the crank pulley.

thanks for the replies, when i said redundant i ment it wouldn't be doing anything except spin.
are you saying that the accord type r is a single stacked pulley instead of the double stack

Nope. Sorry just confirmed in the EPC. Euro-R has single stacked, Accord Type R got the same pulley as the prelude.

13810-PCB-007 is the Euro-R part number.

Why do you need a harmonic damper if it is a track only car anyway?

On a related note, why use a prelude as a track car? From everything I have read they are not even competitive with some much cheaper cars on the track...

Well I guess if it was fully rebuilt with everything perfectly balanced, then you don't really need the damper. Even so, still best to leave it. Companies like Fluidampr, ATI, etc. make dampers pretty much purely for racing/high power applications. They wouldn't exist if there wasn't a need.

Things like the balancer belt on the other hand don't matter for racing. Same with rock hard motor mounts instead of the soft OEM ones.

Wouldn't recommend removing the pulley for the same reason I wouldn't recommend using aluminium pulleys. Just not worth the risk.
