Okay, JK and I spent the day at the dyno with the Grassroots Motorsports TR3.
Remember, this is a near stock engine with the head shaved, a Kastner G3 cam
a decent valve job and reworked SUs and a header and straight pipe.
We started the day with 97hp ((4900 rpm) at the rear wheels and ended up with
104.5. Torque figures started at around 115 ft-lb. at 4000 rpm and ended at
120.
JK says we are down nearly 30 hp to the front runners like Mike Jackson and
Jeff Snook.
Okay, guys, give it up... what should a well tuned LEGAL TR3/TR4 engine make
for power, and what type of $$$$$ commitment will it take to get there?
