Hello all,
I have always nearly always built Triumph TR4 engines with cams from Dema Elgin
Superlobes in Santa Rosa. Occasionally I had installed other cams supplied by
customers that had a valid timing card supplied. I decided with the English
pound being low vs the Dollar I would try the PH1 Cam from Newman Cams in
England. I had heard good things about their PH1 cam as being a great street
cam.
When installing the cam. Information on there website stated peak cam lift was
.295" (it is only .220") resulting in a lift at the valve being .120" less than
stated. Starting off with" incorrect lift figure all valve event figures on the
website are wrong. After several emails I got a two sentence email saying ,set
Intake for max lift at 110 degrees ATDC and the cam will work,
After doing lots of engine modifications I would like a more scientific answer
than the cam will work. Has anyone used this cam or a Newman cam before, or
found that the information supplied by Newman was incorrect. I hate to eat the
cost of the camshafts I bought or incur the cost of sending them back to
England, but I would have no confidence in using a camshaft without having a
correct timing card for the camshaft. -
thanks
