superb! exactly what i wanted.

i can't provide any technical info as i have none. but the end result is very good. at first, i was babying the car b/c of wyatt's prior warnings to "be careful" but after i relaxed a little, i began to open the car up and whoo hoo!!!! the extra power is easily noticeable and acceleration is zippy.

definitely the 2nd best mod i have gotten for the car. right now, i'm very excited and can't wait for tomorrow's drive... and the weekend... and so on...

here's me right now...

 

Did they do a dyno for you? How's the A/F ratio? I would have that checked before you get too wild seeing that the Renntech warranttee only covers the defective pulleys and not your engine.

 

Killjoy! You knew that Buell would find a way to **** on your parade.

I don't think there's a dyno in the town that he got it installed in (though it is a great town to grow up in ).

Let me be the first to say congrats, Young. Makes me curious about what the best mod is, though. Did you have Renntech convert it to a six-speed manny? :p Now we definitely need another Philly/NJ meet!

 

nope, no dyno nor an a/f ratio. and to be honest, i am very very very very comfortable w/ renntech! along w/ amg, kleemann, brabus, etc. of those, i'd be most comfortable w/ an actual AMG car (too bad it wasn't an option last year )

the renntech kit that i got included:
crankshaft pulley
idler pulley
belt

and when it was installed (about 2 hours), they used a new crank seal ring (which cost an additional $16). i have the oem parts (except the old seal ring) in case, um... actually, i don't know why but i have them.

 

Young, can you email me the price of those mods along with the labor cost? I am interested on getting those mods. Either the renntech ones or the Evosport (still under development though). TIA

my email r_1_c32@yahoo.com

 

thanks! yeah, i'm up for another meet soon. heheh, the best mod i got was the little SL emergency brake pad cover! $12 for that little thing! what a bargain. um, i guess others may feel differently.

 

Hey, all the crap I took on my pulley, it's not warrantteed, stop driving your car before it blows up. Now I know the truth, Renntech's warranttee does not cover anything other than the pulley itself, same as Kleemann, sames as ASP. All the pulleys are the same (except for the much lower power gain claims on the Renntech), it's who's name is on the box that's worth $1,300 extra and nothing else. If one pulley gives you dangerously lean a/f ration then they all do. Personally I don't think it's dangerously lean but if you believe it then stop driving that car before it blows up!

Look at what Renntech puts in their warranttee, does this sound like a company that stands by the effects of their product any more than ASP or Kleemann?

If anyone wants to see the full warrantee let me know and I'll e-mail it to you.

 

"Buell" only asking you to watch out from our experienced and not trying to pissing anyone of. It know it felt good, just like when i installed my pulley. But i didn't know about my A/F ratio until i dyno car. So far i know of four people that has installed the pulley and dyno their car showing 14.0:1. This is not danger if you would just drive it normal. But if you race or do across alot then you are asking for trouble. Since your kit does not came with any source fuel aid deliever (chip or fuel pressure regulator), i can warrantee you that your A/F ratio are just like our's. I have never seen any person or manufacturer show their dyno with A/F ratio. They only show their impressive hp/tq gain. This you can tell by "butt dyno". There's no doubt the gain is there !! Buellwinkle is only try to help you from his experience.Let me ask you this, do you experienced longer warm-up then before in the morning when the engine is colder? Here's one of the rule, the car will take longer to warm-up when "lean" then "rich" condition.

 

wait for GIAC to come out with their chip and afterwards, when they make adjustments to the chip for a pulley (they put a pulley on a test car and then adjust their chip so that you have a "good" a/f mix among other things), to seriously consider the GIAC chip w/ pulley.

From what I understand, the chip is still being developed and they will come out with a chip, and then come out with another chip for a pulley modded car. Knowing GIAC's reputation, they will probably give you a lot more --- than the 10-12 hp that other chips give you.

 

linh, i don't race. so thanks for your concern.

i had no plans to chip the car. but i'll re-evaluate when the GIAC comes out.

personally, i'm quite happy w/ the amount of hp and ft/lb gains that i've gotten so i do not feel a need to get any more... well, at least for now

 

Right on! I could care less about the detailed technical aspects of the product as long as I could say that I had one of those tuner parts under my hood. Estimated horsepower increase is also good enough for me, I don't need to dyno the car. All this talk about optimal temperature, being at sea level, etc. is all nice to know; but really, if someone pulled up to you at a light, would you really say, "can you meet me tomorrow morning instead at 7 when the temp cools down? Oh and can you meet me at the bottom of the hill so we can be closer to sea level?...And page me to remind me to place an ice bag over my supercharger before we run!" Real life applications only need estimates. Besides, a big risk is taken anytime we mod our cars, warranty or not.

 

Ditto.

 

Personally, I don't care what happens to your car, just don't go spreading misinformation about the Renntech warranttee. They warranttee the pulley, same as anybody else and nothing more, nothing less.

 

So....what's the first best mod you had done?

 

That is a lie.

Please email me your version of the Renntech warrentee. It sounds nothing like the one I was sent.

 

the quote you posted are for vehicles that do not have mercedes warranty.

here is the warranty for coupe owners - note that labor is also warranteed for up to 4 years:

Exactly, why worry about the brand name, how and who did the dynos or the warranttee, it's power you are after, the more the merrier. That's why I can't for the life of me understand why if you were going to go this route and take this risk why not go with the vendor that provided the best bang for the buck or just the best bang if money is no object. Look at Renntech, 20 HP (assuming you get the entire kit and not cheap out on the filter) you are paying a whopping $85 per pony based on their website prices. Get any alloy pulley and the HP gain almost doubles and the price is less so you get between $10 and $20 per HP. So no matter how you look at it, the Kleemann or ASP billet alloy pulleys' rule.

 

hey buell
i think there is a comfort level that a big name gives some people. if having that name on the box makes them sleep better at night, more power to them. you have done your best, and brought a fine product to the table. you can lead a horse to water, but can't make them drink. i was talking to a guy yesterday. he is looking at having a pulley made, and i asked him what he was thinking of for a selling price, and he told me it was likely to be 299 including the belt. i said that was a great price. and he had the best reply "it's a piece of alumnium, right?" i know it has the steel sleve, but it was a great response. it is a pulley for crying out loud. a round piece of metal that spins a belt. nothing more. can everyone stop making it sound like there is some magic going on. " we have done extensive testing" oh really. you made an effectively larger gear! does a shimano make this huge deal when the front chain ring gets bigger by a tooth?

 

i'd have been ok w/ the kleemann kit too. i just wouldn't get the ASP pulley.

if you don't understand why, then don't worry about it.

 

ASP thought they can do it for $299 but the complex machining and cost of the materials led to the slightly higher price. I'm more than willing to help anyone make any performance goodies for the Coupe so if they need any measurements or tips to save them from grief let me know. Competition makes for better products at reduced prices.

Since there are 8 companies making a pulley for us and 2-3 more in the works, what we really need is a intecooler replacement for under $500. I hear 2 people are working on this but until it's out I don't believe anything. It's really just another hunk of aluminum so it shouldn't be a big deal.

Also a good inexpensive intake would be great. I've proven on the dyno that there's 6hp and 2 ft-lbs of torque to be had so it could be a good product.

 

Buellwinkle, I've figured it out. ASP doesn't have a "cool" sounding Euro name like Kleemann or Renntech! No precision German engineering, just stupid Americans building a cheap pulley on a CNC machine.

 

I don't race at the track either, but still want to be able to redline my car in all gears when I feel like it. Did you just want a little more mid-range power?

 

jeez, that is so stupid... thanks for belittling me like that. i return the sentiment.

 

If that's second, what's first?

 

You could say the same thing about a C230 compaired to the WRX, the WRX if much cheaper hp wise.
