Subject: [Fot] Tr6 Race CAr Cam
Having now had several successful track outings, I have come to an =
observation about my car's performance. It is a petrol injected TR6. =
Flowed head, Goodparts header, and cam whose maker I now cannot =
remember. 320 degrees, .5 lift at valve, and pretty early and long =
symmetrical input/exhaust valve timing. 104 degrees lobe separation.
Car reves past 7000 rpm easily in 4th [4:11 rear end]. The problem is =
low/midrange torque.. I was slightly out dragged by good Spitfires =
coming out of turn 10 onto the straight at Laguna. By turn 1 I was =
faster than them. Power comes on too late and torque needs to improve =
at low end. Looking for recommendations on a more appropriate duration =
and input/exhaust open/close timing.
More importantly, I need a recommendation for cam vendor/recommended =
grind. Had a Kastner S9 in my last [now stolen] car -- but the =
gentleman who did the grinding has pasted on and Moon Eyes no longer =
does them.
I know I have not said enough about the current cam -- just I am away =
from home and do not have the cam grind card with me.
