what are your numbers?

 

mine is 200 psi all the way across, im just wondering if that is to high for a boosted motor, im running with a B18C1 bottom end, wiseco flat top pistons that should be about 9.5:1, with a B18C1 head but im running with a B16 head, i would have thought it would have been lower then 200 psi. BTW this motor in my 94 GS-R, not my Type R

 

130 across in my boosted motor

 

TeamCracka, what is your set up how did you arrive at 130 across?

that sucks dude sorry to hear that.

200 is good, especially with that compression ratio.

je 9:1 pistons 180 across all cylinders

 

alright thanks, so i guess i should be alright at 200 psi?

I've got around a 9.2:1 CR, but I'm not sure exactly why every cylinder is at 130... I'm not too concerned since it still idles/runs fine and still pulls really hard at 8psi, but I'm planning on a rebuild in July so as long as it runs until then its all good

 

How many times do you crank the motor before you stop?

Disconect your ecu or whatever way you prefer. Crank the motor for 5 rotations @ wot.

 

230 across

 

150 Across using weisco 9:1

 

the 9.1:1 wiseco pistons, those are the flat top pistons right? Not the dished ones?
