No it kinda is what he says it is. Been around for a while. Technoresearch is the company, look it up. He makes it sound like his guy(Danny's Cycle Service) is the only guy that can do it but there are others. The Dyno Difference in Dallas has or had the same equipment.

The 255s have great torque, but will not cool down the motor. They run alittle warm. The 48s run nice. I've used both in a 96.

Resulted in 92 horse with 105 #/ft of torque. Don't get hung up on hp numbers... the torque (and where its range is) is the key.

Good luck,

With ONLY CAMS and a Stage 1 You're NOT going to have both stump-pulling down low and big peak numbers as well.
Look, I don't want to sound like I am arguing. I get your point but you misunderstand my original question.
Here is a quote from my first post "I want the Best TQ available in the low RPM's as I can get but I still want Peak HP in the 95 to 100 hp range"

I have seen hundreds of dyno sheets with bikes similar in mods to what I am doing and I see TQ in the 105-110 and HP in the 90 -100hp range.

I guess I should have worded my question differently. How about this?
I want to have peak HP in the 95-100hp range, what cam will give me CLOSE to this and ALSO have the most TQ that comes on earliest in the RPM range?

Note I said "CLOSE" to it, doesn't mean I will get it. But I would be dissapointed with anything under 90HP.
Torque that comes on strong early is my main goal here. But no matter what cams I have seen, I rarely see a bike with over 100 TQ that doesn't have at least 90HP or better to go along with it.

Yup, Doc is having good results with that cam. EPA cam or not, when you get those numbers it's nothing to snooze at, but also like you said, more important is if the power is in a range on the power band that is useable for the way you ride.

So, if your looking for the answer to your question.... SE 254E.

I've got a fraction of a point under 90 HP and a fraction of a point under 104 TQ, with just stage 1, Woods 6-6 cams, and a good dyno tune. But I don't have the power curve as far to the left as you're looking for. Mine comes on strong between 2,500 and 3,000, peaking at around 3,750. The 255's will give you stump pulling power almost immediately, but without higher compression or head-porting, I doubt you'll get even 90 HP. Probably around 85, but it's possible to hit 90 with your 103". I could post my dyno sheet if you want to see it, but my point was just that it's hard to have "the best of both Worlds", with stricly cams and a Stage 1.

Points well taken and good to know about the 6-6 cams. I am no tech by any stretch of the imagination but I an wondering if your true duals are hurting you #'s a little bit?
And I am hoping that sticking with a slightly more restrictive de-catted stock head pipe that I see a little better #'s than similar set-ups running aftermarket free flowing headers?

I would go the 2-1 exhaust route for a little better performance but I like 2 pipes on a dresser and I don't like the sound of a single pipe.

I don't think there is a bad cam mentioned here, Andrews, woods, HQ's or screaming eagle. The 103" reacts better with a little more overlap than the stock 96", best not to over cam. IMO the 48 and 255 work best in lower rpm applications, the 54, 254 and 555 work better in the mid to upper, the 103" does not like to run below 2,200 rpm with heavy loads. Find where you ride and pick a cam from there, Good luck with your
power grail.
