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.

Exactly, softer off the seat but fast or more aggressive thereafter. Also i was told the base circle of the cam is bigger, which it is huge, and inturn affects the .200 range of the valve openings. This seems to give the thing gobs of low end torque!

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.

Sounds good to me!

What valve springs are people running with the lsl lobes i was thinking PAC 1518 singles

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.

Im running the 1518's with EPS lobes. About to find out soon ( if I can ever get time to work on this thing... )

I dont see these listed on their website. Are they considered the LSr lobes?

ramairws6

iTrader: (33)

Yes the LSL is virtually the LSR lobe...........

SweetS10V8

iTrader: (4)

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.

Patrick G

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.

Man, now you know that everyone isn't going to do what it actually takes to use Comp 26918's or even Pac 1518's capabilities with the LSL Lobes .
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

Hmm So what kind of life expectancy can one expect with valve springs on these lobes? Are they as bad as XER's and require practically annual spring changes? Also those 1518 PAC's are nitrided for longevity so any thoughts on how often we should be changing those particular springs on these lobes? I understand the only way to truly know is to pull them and test them but as a ball park guideline is more what im trying to figure out here.

^ 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".

What's the base circle on the LSL lobes?

Aussie 6L

i've just ordered a set of 26926 comp doubles with retainers they are designed to suit the lsr range of cams, seems thay don't need any machining etc too. Must be popular two week backorder atm
