Lingenfelter Pulleys
 
Getting some supercharger upgrades from Lingenfelter Performance this winter early spring. Does any have LPE pulleys? The top pulley is offered in a 2.55 and a 2.35? I've been talking to Ryan at LPE. He said to avoid belt slip to get the 2.55, does anyone have the 2.35 and have any problems with it?
Or just rocking the 2.55 and adding a few more lbs of boost when tuning?

Thanks Brandon

"The Baron" will chime in on this one. He says to get the 2.35 and be done with the pulley situation. He has it on both of his LSA cars and says slippage has never been an issue. He owns a CTSv and a ZL1.

Or do a lower pulley. Parts are more expensive but the labor and effort put in to it is much easier. And no belt slip, grip is actually better.

Ask about a Crank Pulley instead of a supercharger pulley, You can spin the blower 5% 10% 18% 22% or 27% all with the Stock upper pulley and maintain Minimal belt slip.

The parts are more but the labor is Less and makes swapping pulleys a breeze.

most belt slip occurs at the crank actually so if you are concerned do an overdriven lower. We did a 2.55 upper and 10% ati lower and had absolutely zero belt slip. if you want to really go in depth with all the different setups we have done please feel free to call, pm, or email us.

Please show proof of this because it makes no sense the crank pulley has the most contact surface and the supercharger has the least.

More contact means higher coefficient of friction.

Cars with belt slip ie cobras which we have done a bunch of from a small upper going to an over driven lower than showing no signs of belt slip.... I agree I didn't think it would be that way either but have witnessed it multiple times with many different setups.

The bely slip will always occur at the supercharger pulley because it has the highest load and smallest surface contact, this is why we prefer the stock upper and make changes with the lower

Joe@CPR.com 11-13-2013 01:56 PM

you also typically get a max of 180 degree's of belt at the crank pulley instead of at the supercharger pulley which see's a greater degree of wrap. no point in arguing as we are both agreeing doing an overdriven lower is the better move.

Johnny@MTI 11-13-2013 02:11 PM

we have ran them all. we got one ZL1 up to 950hp without any belt slip. the LPE parts are very nice.

2014CamaroZL1 11-13-2013 02:18 PM

In general, is there any reason to pay the premium for the Hennessy parts over the Lingenfelter ?

My apology, What you wrote must have been a Typo because this is what I responded to.

I think you meant Supercharger pulley.

I'm running the 2.55 upper and would of did the 2.35 but need injectors for it.

The Baron 11-13-2013 05:05 PM

Iv got 2.35 on 2 cars.. there is no belt slip issues. The 2.55 is a waste and is sold to get you to buy the lower and spend money. Period..


a 2.35 will make 15 pounds of boost.. I always lol when I hear about belt slip on these 1.9.s.. it is basically complete bullshit.

The Baron 11-13-2013 05:09 PM

And the LPE pulleys are made by the same company that makes OTHER places stuff.


I like lpe stuff. Its good quality..


turning the snout down to fit the 2.35 is all the "extra" work needed and is not a big deal. ANY machine shop can do it while you are having the old pulley removed and the new lpe pulkey adapter put on. Then you can do the 2.55 realize im right and spend the extra 100 on the 2.38 later lol.

But How do you REALLY KNOW FOR SURE?

Belt slip is very illusive and many times we can only find it on a dyno while logging Manifold pressure with the Dyno Sensors.

Belt slip occurs during throttle transitions and you won't even know it.

Belt slip must be extreme before can be seen on a boost gauge in the car while driving.

You could have a consistent 10-20% slip and never know it.

The pulley diameter driving the supercharger is under the most stress and 100% Traction Never Happens.

I know it by putting miles in it. Its very simple. belt slip creates dust. I have a combined 40000 miles now between 2 cars and that pully setup.

my hp never leaves my zl and I prob make 3 logs a week just playing around.

The 2.38 fir a simple bolt on car is the answer, period. The INLY reason to do tje 2.55 and a lower is ..

a. You want to do the 2.38 and 10% lower for the track ( dont do this fir reg driving unless you want to kill the blower, ask me how I know)

B. You dont like money. .

Belt slip does not create dust unless it is excessive to the point of hearing it.

We Use Laser Optical RPM sensors on the pulleys and dyno the car and bring up the graphs trust me there is ALWAYS belt slip and it always gets worse with smaller supercharger pulley.

are you saying for a daily driver to not go below a 2.5 pulley? getting ready to do some mods but mine is a daily driver with 28k miles in 19 months.

IF THAT'S THE CASE THAN WHY OFFER A LOWER PULLEY WITH THE 75RWHP K IT INSTEAD OF AN UPPER PULLEY?
SINCE I HAVE THE 75RWHP KIT WHAT UPPER PULLEY SHOULD IN USE TO GET MORE HP/TQ?

The Baron 11-14-2013 10:11 PM

No. Im saying use the 2.38 and stock damper.

13ZL1BLove 11-15-2013 02:49 AM

Ryan from LPE seems to be pretty solid on trying to get me to buy the 2.55 to avoid belt slip. Idk why!

All the vendors on this page are telling you because of belt slip... :iono:

I think you misunderstood, those percentages are all lower pulleys that are available for your ATI Superdamper.

You can just swap the lower when your ready.

13ZL1BLove 11-15-2013 04:29 PM

Emailed Jeff at LPE and he is saying to get the 2.35 just gotta machine the OD on the snout to get it to fit. So now I'm questioning why Ryan keeps telling me about belt slip and Jeff isn't concerned the least bit.
