Hey--x_scrambler3,
I've had mine out for some test runs. All I can say so far is WOW!!!
Night and Day difference between what I had. Seat of the pants feel is
ALOT faster. As soon as I get the engine broke-in, I'll do some 100 yd
timed runs. The best time that I ever had on my TB with a clutch kit
and a pipe was 6.89 sec. My brothers 400 sport was running in the
6.66 to 6.36 sec. in 100 yards. His 400 had a pipe and clutch kit
installed. He just up-graded his with HPD's trail porting and billet head.
He has rode the reed converted TB and can't believe how fast it feels.
He thinks it would have beaten his piped 400!!

 

As you can see I have the race porting allready an it improved it alot. I will be looking for more info when you have it. I just got some new pics from racing one with me comen over the big doulbe will have to get it on the net

 

no sorry,i was talking about power gains,a liquid cooled engine produce more output than air cooled engine...
