I am currently in the process of planning out my next build i recently spun a bearing in my bottom so now that its time ot rebuild im looking for what ever input i can get. What im trying to do is go with 13:1 forged pistons sleeved block and i would like to to run a 150 shot. The motor currently has Skunk 2 stage 2 pro series cams. Is 13:1 to high for that much nitrous?? I am still on the line about using race gas. Any input would be greatly appreciated

 

bump please need input

 

I think it will come down to the fuel you use, and a great tune. If you throw too much timing at it, things will go boom!

Sleeving the block and running forged pistons will help for sure though.

Are you planning to do a dry shot and add fuel from the ecu?

Oh and since you have already experienced a spun bearing, make sure that all of the bottom end clearances are spot on, and the crank is balanced perfectly, the 95 mm stroke is not very fond of high rpms.

 

i was already running at 100 wet shot and im still on the line between which fuel i would use what are your recommendations

 

also would it be better to run 12:5 compression pistons??

 

If you have it available, I would run E85, and 12.5 might be easier to work with on pump gas if that is your only choice. If this is a track only car, go with the higher compression and either E or race fuel.

 

one of the neighboring towns where i live sell 110 octane right from the pumps do you think that will be good enough
