Haha thanks. Will do next year as cars in storage now..... -
I would be looking at the tune mate. How do you know that you have such a low dynamic compression? I had to dumb mine down because it was too jumpy when taking off (too much torque). What ECU? Do you need help with the tune? -
Surely the cam timing is set to something stupid at low RPM? -
Hi guys, Sorry to butt in and take it slightly off course, although still on the VCAM subject. I had VCAM put into my Tomei 2.8 bottom end and I struggle to take off because the engine has very little torque caused by VERY low dynamic compression at 60psi. But once off the mark and especially on boost, the engine rev happily all the way to 8000rpm and makes 630hp at 20psi of boost on E85 at the rear hubs. Has anyone had any similar experience or any suggestions on what might cause this low compression at low rpm? I am in the process of converting it into a 8hp transmission and with this low torque, the engine would not even stay running until the throttle is opened to more than 30% and then I loose all vacuum. -
