Disappointed in new cams!

RE: Disappointed in new cams!
Well, here I go again, (posted same in Dyna Glide Section)
I am linking you to a series of posts regarding my Andrews TW37G cams install.
I went from an out of breath 60 horse engine to a 79.66 horse screamer due to my new cams. This motor does not stop making power and is only hauled back by the rev limiter. A smile a minute since cam install.

Who installed the cams? Possibly timing off on cam install? Did they really put new cams in????

RE: Disappointed in new cams!
Sorry to say, I have heard a lot of Theory on certain cams, need higher compression, need at least 95 C.I. upgrade, needs head work to perform,only a high rpm cam, etc.
What I have mentioned, and shown, in my posts are the Actual, net results of a real world install of a set of TW37G's on a stock 88 C.I. mill. Except for the pipes and SE1 AC, and dynojetted carb, my bike motor is bone stock. All I added were the S&S cam gear drive and Andrews TW 37G cams.
No theory can dispute 80 ft/lb's of torque from 3,000 to 5,000 RPM, with a max of 88.49 ft/lb'sat 3,500 RPM. With my CV again re-jetted, I am now over 80 HP also.
Fact over theory, I rest my case.

I didn't say you wouln't realize a modest gain in performance. Your dyno shows that! My point is simply that that cam would benefit from headwork and proper CR. Imagine what your dyno would look like if you did!

This beast should be easily in the 100/100 club with 98 C.I. and heads and compression increase!!
But as I am riding the bike like a wild man now, I will definitly be in trouble with a 100/100. Believe me, I have used up 8 of my 9 lives already.

Here's what they do in a 95", @ 9.7:1, with mild head work. It ran fine on 93 octane, but in a Bagger, on avg fuel..... ping ping ping.
Perhaps even less timing might have helped, but I've moved on to something different (HQ-0039) and they much better and no pinging.

Thanks everyone for your replies. The most power i have gained was just simply adding a Hypercharger, rejet and 2 into 1 exhaust with little restriction. That made a HUGE difference over stock. I will have the heads done next and keep you updated. THANX!
