Everyone interested really should buy the MM&FF this month. They go into very great detail on why this charger is better even at stock boost levels. What the hell, here is a piece of the article. This shows how much better it is at different boost levels and why.

 

Trust me even the upgraded Eaton won't even come close to the Kenne Bell! JL

 

I was real disappointed in MM+FF in letting Kenne Bell run the show on all this info. Kenne Bell sells autorotor kits only so he is real biased in his testing. All negatives of the eaton were exploited and all positives were disregarded. The autorotor is more efficient period, BUT it has some negatives: It has no built in bypass valve so if they had done a part throttle temp run you would have seen a big difference in temps with the autorotor being much worse. This is important says after driving awhile and then flooring it, it may detonate initially. Also even though they have the same size case they don't flow the same, they are different designs similar to centrifugal superchargers just because you put the same size pulley on those they have different pitches on the impellers and so forth. If you will note when the blowers were run at the same psi the eaton did better down low and was promply disregarded and excuses were made for the aotorotor. If they had been fair they would have gone to bigger eaton also in the test. I also noticed that the in and out temps on the autorotor were much better than on the eaton this should throw a flag that this test was biased toward the autorotor. Kenne Bell is not below somewhat cheating to help his bottom dollar. ie:selling autorotor superchargers. Again apples to apples the autorotor is more efficient but if properly sized superchargers are used the difference is slight.

 

The article in MM&FF can be directly related to the Lightning. Big gains are to be had by bolting up a Kenne Bell!!! The stock Eaton runs out of breath early and doesn't necessarily increase power proportionally, relative to pulley size. The Kenne Bell AutoRotor design seems to make more power at the same levels of boost. With any blower, as pressure increases heat also increases. However, with the Kenne Bell there is far less heat and much more power at the same amount of pressure.

 

Yea and the adapter plate they ran was really restritive, at least it looked that way. I liked what I saw with the temps of the KB unit. Can you imagine what they could of been with a specific lower intake. I was impressed with the power the Saleen test car made. Its a may try for me. can you imagine this unit and the New Diablo chip ..wow

 

What about sals new blower. How will his compare to the kenne bell?

 

Kenne Bell does have an option for a BY-PASS VALVE for other applications, so I would hope he offers one for the L's kit.

 

The comparison was done with an Eaton M90, not the M112 thats on the L, so the results don't accurately reflect a direct comparison. Ditto on the big gain in reduced intake temps. This is significant and I wonder how much of the gain is attributed to reduced intake temp. For me, the jury is still out on how much pressure these motors can take before grenading. I think this season will be telling once guys with built bottom ends start running more boost. And finally, $2700 seems like alot for a supercharger, will it include any other components? Can't compare it to the Gen 1 kit because that kit requires more components and hardware. G2s are already plumbed for a blower. I'll wait for the tuners that have more experience with Ls, to see where they go with bigger blowers this season!

 

At $2700.00 for the KB it maybe a little pricey but if it has a good upper intake and an assortment of pullies it could be the hot ticket. Now if there are other units such as a modified Eaton at higher prices they may just sit on the shelf and gather dust. Auto Rotor has always been a good design but what hurt them in the past was the lack of a boost by-pass. If the price could just be held to sub $2500.00 it would be great. Kenne Bell also has a very good inhouse chip calibrator (more then just a tuner).

 

If you run the same boost level, the cooler temps of the Kenne Bell should make more power....well theorectically anyway. I wonder if they will sell just the blower kit?..I'll keep the PSP chip.

 

Remember that it supposed to be $2700 list price or full retail and everyone knows only suckers pay retail . If it could be had for around $2500 it'd be pretty resonable providing as WCFan says a decent array of extras come with it.

 

The M90 was used on the old T-bird supercoupes (V6) and is on some mustang kits. Its a much smaller unit than our 112. The HP differences were only around 75 HP betwen the autorotor and M90. I doubt there's more than 20hp difference between the 112 and autorotor. And there are cheaper ways to gain 20hp.

I also didnt see any torque figures. The lightning's arent really big HP vehicles, but our torque is whats makes the stoplight derby so much fun.

Last, have you ever heard an autorotor? Sounds like crap. I'll keep my eaton just for the sound!

 

I don't think the size difference is an issue in this case. The M112 that is on the Lightning is the equivelent of an M90 because of the placement of the SC air intake. Right on top of the SC. Sal mentioned this some several months back.

 

I got 3 words for you guys!

Paxton Novi 2000!

And no I'm not talking about top guns setup with both of the blowers. I'm talking about a 5.4 novi 2000 setup and a custom made upper intake (which would be so easy to do) that could pump out 30PSI!!!!! Thats what I want to do.

 

I thing you hit the nail on the head. I don't see a massive improvement in Eaton vs Kenne Bell. A 20 degree temperature drop is worth about 6% more HP.

Another thing is boost isn't what is killing bottom ends. Horsepower is what is killing bottom ends. It doesn't matter if it's cooler temperatures, more boost, or N20.

It's pretty much apples to oranges, but here is a HP gain from somone switching from a Kenne Bell to a Novi 2000 on a 4.6L Cobra.
