Kleemann, Renntech, EvoSport, ASP Pulley Comparison
I read on here somewhere (can't remember or find the thread) that the ASP pullies produce more boost than both Renn and Klee, is that true? Does anyone have or be willing to provide a quick comparison on the 4 different pullies? Also how is each constructed?

Mmmm... badass car
How about E63TT ... with E55 tranny. Or try the E63 tranny and see how well it holds...
+ Quaiffe
+ 335/25's on rear (cut into trunk) - who needs it ?
+ Lowered
+ Brake Upgrade
OK its stupid - but what is out there that u can take off the floor ?
Mbe 997 TT with uprated turbo's aught to get you close...

Your worst nightmare...
Well according to the ASP tech the Pulley alone will provide you with 45 RWHP!!!!
, and trust me I feel them, I am going to get a Dyno today probably and will keep you guys posted. How much does the kleeman and renntech provide? Anyone?

i belive kleeman is 40 hp with pully and ecu. so 45 with no ecu sounds good. but how long will your motor last? how much boost can you throw at it before it gets pissed?

Here's what I know about the pullies:
Kleemann - takes the OE pulley and takes off the larger outer ring, then adheres a newer larger diameter outer ring (made of aluminum I thought) back to the damper/smaller ring. The outer ring is afixed with pins to prevent shearing off and "glued" in together (for lack of a better term).
ASP - Similar to Kleemann, ASP takes the OE pulley and removes the outer ring and attaches a new, larger outer ring (larger than Kleemann's) welded to the stock damper/inner ring. ASP then re-balances the pulley (which is why you see drill holes it the pulley itself). ASP makes the Hennessey pulley.
Evosport - Creates their own pulley from scratch from billet aluminum. They look distinctly aftermarket (check out their web site) and weigh considerably less than OE, Kleemann, and ASP pullies.
Renntech - I know nothing about their pullies.
I don't remember the exact amount of additional boost for each pulley, but I know they are on the forum somewhere and could be added to this thread easily.
If someone has more detail to add or can fill in my gaps please reply.
Thank you,
Darren

So they make more boost and therefore heat soak even worse than the other tuners on the market. On a road course I bet the bigger pulley is useless as the car will likely shut off due to high intake temps. Threre should be a warning that the car will lose all power when driven hard with their pulley!
Stick to the big names as they kept the cooling capacity in mind when building their parts.
On as 100+ degree day 2-3 runs on the freeway is enough to make a car shut down and 10 0-60 runs on a cold day can do the same (when done back to back for bedding brakes etc).

Here is a quick rundown:
(I do not have my notes handy and I do not recall exact diameters).
1. ASP/Hennessey/Local Tuner Shop - Reworked stock damper, about 1/4'' larger in diameter than any other tuner.
2. Kleemann - Reworked stock damper.
3. Renntech - Reworked stock damper.
4. Evosport - Complete pulley system including:
- Original design brand-new larger diameter friction damper with new bolt.
- Re-designed water pump and tensioner pulleys
- Belt travel limiting pulley
- New longer belt
- Underdriven alternator and power steering pulleys.
Since I designed evosport pulleys, I am biased

Vadim, the one thing that would overtly concern me about doing anything to a crank pulley is the importance of harmonic balancing. If the pulley is significantly lighter won't that have an effect on how the crankshaft sits on its bearings?

.............Did actual test of Kleemann pulley with K2 ECU program vs Hennessey pulley with K2 Kleemann program. Gained 20RWHP with the Hennessey plus K2.

personally...
I like the Evo product. My C32 runs very strong now with a little help on the Sprint Booster.
I just bought ASP pullies for my E55.
2 reasons.
price
and output was more than other ODP systems and I didn't want flash my ECU.
My logic is the following:
I have CPO warranty until 2008 and extended warranty until 2010. I'm only planning to keep the car till about end of 2007.
I don't track the car and I can easily change the IC pump to a johnson high flow pump and do the 10 degree mod for better cooling.
I personally (w/ little help from a mechanic) changed my IC pump on my C32and it is not that hard.
For the price, you can't beat it. But if I had the extra money, I would choose the better brand.

I *flogged* the car at the track with no supercharger shut-down.

Does ASP only sell direct or do they have dealers?? I'd be willing to try one to dyno against my Renntech pulley, just to see what (if any) difference there is.
Edit: I just realized that friggin' Summit sells ASP stuff. Does anyone have a PN for the E55 pulley?? ASP's website kinda' sucks.

I would have loved to try the Evosport pulley but unfortunately Evosport doesn't sell the pulley alone without the software.
Hence I went for something else and am now contemplating trying the ASP one after all the good reviews.

Does ASP provide a larger belt with their kit ? Whats teh kit consist of?
How difficult is it to change this pulley ?
Whats the harmonic damper all about ?
