I chose the OS plug based on having them locally. I have heard the Voodoo #5 last a long time in these engines. My OS P3 plug has lasted well too. Used the same plug from break in and for two race weekends. I did replace it this past weekend but that plug had almost a gallon on it.

I am going to try a Voodoo #5 soon as I have heard such good things.

geez, no response from the experts yet? Try the odonnell 97t if you can get them.

That would be a good start anyway

I agree. Ive tried the voodoos and the OS s. The Odonnell is a much better plug for this engine. Seems to be easier to tune and keep a tune. All my other buddys running them are using the Odonnells also.....

Not worth the argument.....

stay away from the OFNA T series plugs. They are less than desirable with an average life span of about a quart or 2

I am not an Os plug fan but I have been told the p4 is almost as hot but the wire is thicker and will last longer.

i've been running the od 97t in this motor with not one problem i'm really liking this motor and am looking at getting a second not bad for a in between motor till i got my os don't see the point in getting an os now bang for buck this motor rips......

omg i cant wait to race this mill. break in is done and race tune is sooo close to on! i smoked my back tires already! love it! also you can run this mill with the rb 2045 pipe, although it does make it tune sensitive in my oponion.

You reset the idle gap after break in didn't you?

Rex

Can you guys give your Tune set up for 25-30% nitro? I mean HSN and LSN, how many turns out from fully in?

Thanks.

A good starting point is hsn flush and lsn in 1 1/2 turns and idle gap at .7mm. You should need to lean the top some at the track from that point.

Rex

+1 Our out here are close to that as well 11/2 in on LSN and 1 turn in on HSN from flush race tuned with 2081, Voodo #5 plug and Werks 30%. We have had great luck with the Voodo plugs so far.

Thanks,

Those setting are form flush needles turn in. I just saw you asked for how many turn out. Just wanted to clarify
