You might have read...I just bypassed my heater core earlier today. (See post below). Since then, I seem to have lost some power. Is it my imagination? Or would bypassing the core have some effect on performance?

Any replies would be appreciated.

Thanks,

migth increase your coolent temp a bit since the heater core is a mini radiator, but you shouldn't see or feel any noticable change in preformance.
