Has anyone put the 255 cams into a 96 in motor with only an exhaust and air cleaner change (plus some kind of fuel management system). I would be interested in seeing a dyno run. If it hasn't been done by anyone do any of the experts have any ideas on how it will perform as far as low end torque compaired to the stock cams.
Thanks, Dennis
Mike (at Latus) is right about all low-end torque available from the 255s in a stock build. Most '07- '08s with just a stage one (no cam) deliver in the mid 70s for HP and low 90s for torque (tuning with the SERT).
I run Andrews 55 cams, Ness A/C, SERT, and a fatcat exhaust on my 96. Will sit beside a Vrod up to 100mph. Still have a 107 kit sitting in the shed, not really seeing the need to fit it right now, damn thing pulls like a train.
103 kit, 255 cam, D and D fat cat with quiet baffle, and a GOOD SERT tune and Mike says the cam will hang in a bit longer say to 4,000 making like 110 torque. 110 x 4000 divide 5252 = 83 HP @ 4,000.
Really how often do most of us shift higher than 4,000 on a bagger? do the bore on your seasoned cylinders, buy some flat tops, sent the heads to bigboyz for a street port and you have a very reasonably priced modification and quite reliable.
In a 110 kit with mild porting, 255 cams, slip-on exhaust he is showing 116 torque and 104 HP.
With no head work he is showing 108 torque and 88 HP.
With the head work the torque curve shows 118 hanging in there to 4,000-4,500 but with stock heads the torque shows 108 but falling off pretty quickly from 3,500.
I'll post a link and take a look! Note the 100 torque @ 1500 rpm. :yes:
I'm betting a 103, with some bigboyz heads, a D and D quiet exhaust, Cometic gaskets, a 255 cam, and a VERY good SERT tune would give some impressive real world bagger running results. AND not a heck of a lot of money. As to reliability? What have you really done.
WHAT ABOUT HEAT ON THE 255? Does the short overlap of 13 degrees and alow greater cyl head temps? Anybody have a suggestion. The gearing on the new 6 speeds begs for the power to be low as possible but going with an EPA friendly cam gets me worried about pinging in the summer.

@gree: ! I rode a Se110 when the harley demos were here in Sept, the SE110 engine ran much hotter than the 96"ers I rode. I have also read that the published specs for the 255 cam are not accurate.
I have an 08 bagger,,Reinhart exhaust,power commander,SE air filter,I am using the SE255 cams,,The dyno results are,,89 HP with 101 lbs of tork,,a 110 SE has a hard time passing me,,only at around 100mph,,,good mix
Doing cams is a good choice.
But !
Do more homework !
Don't git in a hurry.
Talk to some builders !
Listen and Learn.
And think about what you may do for a total package.
Right now you are just thinkin about cams.
You will be happy for a little while, then want some more to git the adreline flowing.
If you have a total build in mind you can do it in stages.
Don't worry about the numbers.
Look for a package that is gonna take you from point a to point b the fastest but keep the dependability in the motor.
So wait, take yer time and do a lot of homework.
Save yer money up.
Talk to the people that's going to be doing he work for you too.
You want a cam that is gonna pull good down low and not run out of power on top end as fast.
My buddy has some 204 cams and is lookin to change them already.
And do you want EPA cams ? Or Aftermarket cams!:woohoo:
Homework is a good thing.
See you have a 07 bike, the 1st thing I would do is put a Thundermax on it with Auto Tune.
Go to Youtube and watch the videos of Thundermax.
Steve, looks like your doing some great work over at GMR! nice numbers! as soon as I get two years on my 09 and warrantys up I'll be at your door for a 107" build
Maybe not in a 96 inches but in a 95 inches with Big Boyz heads, Khrome Werk pipes, and SE heavy breather, a good tune from Bean, gave me torque from 1500 to 5000 rpm...
you can add my vote for the 204...
for bolt in se 204s ,andrews 37,with improved air intake ,exhaust and better tune is the cheapest power available with great fuel economy ,most other cams on the performance side need a combo of ,compression, air ,fuel velocity and head work ,exhaust,ignition ,and a expert to match the lot to your liking .best advice is to ride a buddys bike or your local wrench s to gauge what you really want .the variety ,like opinions is endless,
