I have search cam threads and have not found what I want. Is there a cam that will still give me low end torque and more HP? A friend just had his done with a 257 or 259 se cam and se tuner and he's getting 111hp and 105 torque. All I got with 255se and pc5 with auto tune is 98 torque and 95hp

 

Se 254e

 

If you and your buddy are pulling those numbers out of 103's then you must have many more factors besides cams...... Headwork, compression, pistons, exhaust, etc... No way those numbers are coming out of a stock 103" with just cams.

 

Go to Fuelmotousa.com and look at their comparative dyno sheets and you will probably find the info your looking for.

 

if your friend is running 257 or 259 cams, he's bumped up his compression....thru either head rework or change in pistions from flat top to tub'ed if used with stock heads. You need to investigate compression requirements and limitations when exploring cam changes...255 is a good cam, but the goals you are looking for need a different cam solution since the 255 does not do well with high compression builds and cams like 257's and 259's do not do well with stock compression senerios.

 

Not always. There are many 103 out there with only Stage 2 (A/C, Pipes, Cams and tuner) making over 100 Hp/Tq just look at the dyno section.

Here is a link off Jamies site at Fuel Moto 103, with stage 2 (cams, pipes, a/c and PV) no head work 100hp/113tq

and one tuned with PCV 98hp/109tq

Im getting ready to do cams and will probably stay Se parts. Im looking at either the SE 204 or Se 254e and expect to break the 100 mark. But what is more important is the ride , if it puts a smile on your face after the work it was worth it, too much getting caught up in #

 

Like Beav says 254's. I just put in a set in my 2011 RGU and very happy. Strong from idle thru redline.

 

So by these "calculations" if they did headwork and bumped up the compression they'd be putting out more HP than 120R's!!! LOL

 

No 1/4 mile runs for me, so i went with the 255's. Better for my pig of an Ultra Limited anyway....was really surprised at the top end gains!!! lol

 

Agreed! If I don't see a dyno sheet for those numbers claimed I'm calling bullshit!
