well, after a deceptively easy breakin (i was used to go engine!) , yesterday i went out and got a nice tune to my clocked b5 and... damn! i tought that my GO 7pt was revving great ! were i used to have enough space to stretch the legs of my go 7pt, with neals b5 im running out of space and i can definitely see that this engine breathes better that the stock engines i've had before. tuning is very straightforward. engine temps stay very on the cool side, even after multiple agressive passes on the street with a good tune, engine stayed between 195-200 and dropping as soon as i was idling.
and what an idle, over a minute to empty the tank without a hickup.
now if the rain could stop... i need to race...now!
