MK:
Impressive power, but what did the curve look like below 2,500
RPM? He needs to be generating about 170-175 HP at the flywheel to get
that much to the rear wheels, and I suspect that you would not like to
drive this on the street for more than a few minutes, less if you are in
stop and go traffic. Just a suspicion.
Also, with rocker ratios that high, the "over the nose" loading
on the cam lobe would be getting high enough I would worry about lobe
and lifter life. Great for racing, not so great for a road car.
Can anyone post the curves in a location that can be viewed on
line? Is the article available on a homepage somewhere?
Just curious,
Vance

Hi all,
Anyone see the article in Sept Classic Motorsports (sister mag of
Grassroosts Motorsports)? Had Jim Howlekas TR6 and Richard Goods TR6.
The
one thing that caught my eye was the Dyno report on Richard's car. He
had
Torque and HP figures in the mid-140 range at the rear wheels! In
addition
this was a very flat curve. Some details were listed including the fact
that he had prototype rocker arms of 1:85 ratio vs the usual 1:55 or
1:65
range. Compression was 10.8:1. I believe the cam was the GP3. Cool
stuff!
MK CD255, etc...
