Installed SE 254E cams

Just installed new SE 254E cams in my 2007 FXSTC 96 cu. in. with Arlen Ness air intake and Vance and Hines big shot staggers. It really changed the torque curve over the stock cams. It has a lot of torque in all the ranges. I have 82 ft/lbs at 2200 thru 4300 rpm's and from there it is 86 ft/lbs until 5600 rpm's where it starts to drop off. I also ended up with 82 hp. I am very pleased with the torque and horse power of this setup. I am also going to put in NGK Iridium plugs that I was told would gain a couple of more hp.

Looks like they are one step up from the SE 255s? -Tutt

The dealer told me this and thru some research on the internet it looks like the SE 254E were made for the smaller lighter bikes like the dynas and the softails and the SE 255 were made for the bigger heavier touring bikes. There is no comparison in the torque at the low and mid rpm's compared to the stock cams. I didn't really see a big gain in torque or hp numbers compared to the stock ones but it put it in a more usable range in the rpm's.

Those plugs will do nothing for you but cost money. They could cause combustion codes as well

Needs a good tune.that's about what a decent stage 1 should be.
what type of tuning device?

HD Screaming eagle race tuner. I just got it back from the dealer and they tuned it.

It's basically a stock motor other than the cams.

Hey Noodle,

Thanks for the post on the new 254e cams. I have been waiting to hear/see some dyno results. I have been back and forth between the 204's and 254e's on my 2010 96 SG. Your numbers seem low in my opinion, others with the SE 255 in a 96 are in the 85-90HP and 90-100TQ with a good 2 into 1 exhaust, air cleaner and programmer. The 204's in the above setup are a tad higher in numbers as well. A upgraded cam should produce numbers higher then the stock cam and also change your torque curve like you stated. Maybe the 254e's needs more compression as others have posted..
