Cam Discussion New LSL Lobes from Comp Anybody have any real world numbers or results out there. I know the Lobe is quite new but it seems like everyone is secretive about them?? I have switched to a new LSL lobe in my all motor 441 and love it. The driveability is a ton better with gobs more torque on the bottom end. Lost about 10 rwhp up top from my last cam but it just seems alot funner to drive!. I did take it to the track but had alot of issues. The difference was i went from a 10.46 to a 10.50 in the 1/4 but my 60ft went from a 1.49 to a 1.42? I know, different track different day right. Anyone else have some real world results? 
So where do these LSL lobes fit in the scheme of things? Are they more or less aggressive than XER's? I thought these were a bit more knarly and comps latest valve spring munching lobe but maybe Im wrong here?

I had a discussion about these lobes with a Comp rep at a Vengeance Racing cookout a couple years ago and the following is what I think I remember from that conversation.
As I understood it, they fall between the XER's and the LSK's lift wise. The LSL is softer off/on the seats than the LSK's and the XER's and is designed for stability while still offering considerable lifts.

Im about to run a PatG spec'd EPS lobe cam on my new 6.2L set up. No clue to how/what makes them different but they seem to work very well of late. I wonder how they compare to these LSL lobes as I was told similar traits about the EPS lobes that they are milder on the valvetrain and easier off the seat. Sounds pretty similar...
This is a pretty accurate statement. These lobes have been available for around 2 years (in custom cam applications) so there's tons of real-world numbers on them. They're an excellent lobe with better stability than XE-R lobes while making more power.

I was told to use a Dual valve spring with the LSL lobes and that you can get away with PAC 1518 or Comp 26918 beehives when using the EPS custom endurance lobes, which is a slightly milder and less lift version of the LSL lobes.

LSL is the lobe name, LSR cams use LSL lobes....... LSR=LSL
I run 918s on my LSR cam, but only because my valvetrain is very well setup and tested. The 26926 is the new dual spring designed to work with the LSR line of cams.

Most people will need to run duals.

.If i understand it correctly....the proper selection of the correct v-spring has more to do with than just the lift capabilities of a v-spring vs the actual lift of the cam. So it would be safe to say that the LSL lobes should come highly recommended to be used with a Dual Spring kit.

I'm fitting a 239/247 lsr cam to my 6L anyone used the 26926 double springs. Comp say they designed for the lsr cam.

My old set up 224/244 crane was running 918's and i'm thinking they won't be up to the task.
Are people changing retainers etc????
Cheers Paul

Exactly. If you are running heavy solid stemmed valves, it's best to run a quality dual valve spring with LSL lobes. If you have lightweight valves and rockers, a good beehive like a Comp 26918 or PAC 1518 will control the LSL lobes.
Most people will need to run duals.

^ I had some comp 921's pulled after 10k miles of use on a Comp LSL lobed 231/246 .617/.623 115LSA cam and they all pressure checked right on spec. Never had a chance to repeat the procedure as the car was hit and total'ed, but the next interval I was going to pull them on was 15~17k miles. I would think 20k would be a nice safe interval, but I have no testing to support this other than a "hunch".
