I would like to have faster spool and more mid range torgue, and good power curve to the rev limiter (7500rpm). The engine has 10.5:1 compression, running on ethanol e85.
Last week I spent on the internet finding some numbers. I´ve heard that the best way is advance both cams and lower the overlap. Is that true ? Could you advice me some numbers ?
Next problem is that i dont know how to properly time the cams. I have instaled degree wheel on the crankshaft and the gauge for measuring position of the cams. I think there is a problem with hydraulic lifters, i´m not able to find surely when the IV and EV opens, when closes. Everytime i recieve slightly different numbers or i cant get on the duration number 240°, but only around 200°. I´m using 0.05" technique.
I think i will try easier lobe centerline method. Can somebody tell me some numbers to set?
Intake camshaft lobe centerline
Exhaust camshaft lobe centerline
Lobe separation angle
IVO, IVC, EVO, EVC
Thank you for help
