RS-Enthalpy flew up to WA state, we dynotuned stock SR, it put 258whp at 14psi on a dynojet at 85F in summer. that's t25, 370s, walbro pump, exhaust, intake, and fmic (cxracing).
The objective of engine break-in is to load the piston-rings to they are pressed against the cylinder wall with pressure as to SEAT. I drove my car 18 miles to the dyno after an initial operating temperature "break-in". During these 18 miles it's all on throttle, engine decel, on throttle, engine decel. Put it on the dyno, and you could see it make more power every pull. FIrst like 270, then 330, then 440whp at 15psi. (SR gt3076r, E85). It was awesome to feel the car make more power as I drove it to the dyno also ^_^
When you first start your car you want to do on throttle, off throttle, first between the 2500-4500, then slowly expand that range, but keep out of 20psi+ hahah. After the idle oil change and the initial drive oil change, slap it on the dyno!
Either it blows or it boosts!!! lol
