Trust me, I've spent quite a bit of time looking at those charts. And actually, it's everybody's opinion that I'm looking for. Particularly on lower end torque value cams. Seems that there are a few different manufacturers making a cam or two that would probably work out, just looking for some input from those that have tried one, or two, of them. As soon as I figure out what compression ratio I'm going to end up with, I'll have a better idea of which way I'm going to go, I think.

You need to keep in mind that the largest factor to good low end torque is compression.. This is why the 48's work well with stock compression 96" and 103" TC's.. With the early IVC (29°) less compression is bled off making more power sooner.. So now you take a cam that has an IVC of 45° it's going to take more static compression to reach the same cpi as the 48 produces..Over lap also makes a difference in charging the cylinder..

Never seen anyone post up valve timing events on the TTS Cams, Steve Cole sure as hell aint giving them up. Even the supplied cam card doesnt list them , only lift numbers. Have you ever tried one? Know anyone that has?

I never gave them a thought when I did my build and I'm more than happy with my Tman 590s but if I were to do it agsin, I would seriously have to consider the TTS150.
I an M8 build, I've used the 200 and 250.
the 150 works in either a twin cam or M8 and his 175 spanked the woods 22X in an m8 107 all the way across the board and carried out to beat it by 11hp. Started out equal at like 2200rpm.

Nope. Steve doesn't make public his cam cards. Outstanding torque curves tho. Like I said. They start early and keep going.

Yeah I meant e 150 for either but my point is power, whether low end or otherwise, is accomplished by cylinder fill. Compression is just one-way to accomp!ish this. Exhaust events can contribute as well as intake in the form if scavenging. Obviously Steve knows how to accomplish this and with cams that aren't brutal on valve trains.
Often other cams valve events are far from what their cam cards suggest anyway.
I'll have to admit I wasn't fond of not knowing valve events/lift etc.. but I've seen too many outstanding results not be a believer.
Ive used his 200 and 250 in several upgrades for M8 friends.
You can see plenty of results if you look at other places besides these forums, btw. Dyno charts of the 590s and and a host of other good cams can't be found on FMs site either, btw.
Just ask Porkster. He's tried many so called popular M8 cams before finding a cam that stuck out above all of them.

I have gone to the TTS175 now(which you suggested earlier) and a Bassani full length Road Rage, love it just as well as the 150!!! Thanks @Steve Cole for your contribution to the performance world.
People could learn from your experience having tried like 5 different cams in the same bike including the "poppular" but overrated 22XE imo.
Not in everyone's budget to do what you did. Glad you found what gets it done for you despite all the advice you had to weed thru to get there.
Popular isn't always the best.
knowing what MotoJockey is looking for I would seriously look at the TTS100 as a stage 2 103.
Funny, all these stage 2 103s that have been done, no one hardly ever suggests or considers them or does a comparison.
Maybe he could since he's running the 48s now?
