The part number was: ASP Pulley 331380, correct?

 

I believe so.
The ASP site is finicky. This is the link per MBWorld:

Just curious - does the increase in RPM (caused by the smaller pulley) of the blower cause a decrease in reliability over the long run?

 

I just called the 1-800# and ordered over the phone...and yes 33180 is correct.

 

hi guys this is my 1st post here

i just read the whole thread but maybe i missed something. this pulley obviously made a huge difference on your crossfire but have you actually had a chance to dyno yet so we can see the actual tq and hp gains?

 

There is a dyno printout from the MFG in my gallery.

 

Thanks. The dyno sheet was labeled for a c32 pull...is this accurate?

Also, am i seeing correctly a 19hp gain but a 17tq loss...???

Well, I just had my CAI and Pulley from Needswings installed. We've had a lot of snow around here so it it is hard to find good roads. Anyway, I put her thru her paces. Couldn't get any top speed figures, but the increase in acceleration is tremendous.

The fellow who did the work for me (who has been driving HP cars since the '60's) said he has never seen such a change in acceration with the minimum amount of work on the engine. She's a rocket ship and you don't have to worry about the seat of your pants telling you that!

Next week her ECU goes in to Inmotion.

 

Well I have the LSD in the rear and your post has made me a believer, Iam going to place the order cause if I can pull the rear the pully is a no brainer, thanks woody.

 

Although quite expensive a set of AMG wheels like the SLK55 uses would be nice and a big pair of DRs would probably fit

"The tires specified by AMG for its version of the SLK are 225/40ZR-18s at the front and 245/35ZR-18s in the rear, mounted on AMG's own spectacular-looking 18-spoke aluminum alloy wheels."

 

Or these Mercedes OEMs (f 8x18, r 9x18 as opposed to ours being 7.5x18 and 9x19)

As far as getting traction i recomend the Nitto Envo, I launch consistantly at 2000 rpm's and have yet to have it break loose. Although adding a pulley and intake might help with the chances of it spinning out. i went to a 285 in the rear and a 255 in the front, i set the air pressure at 25 lbs and run all night. Dude there is video on youtube of an SRT6 with pulley and intake and it did 12.4 at 110, so I hope you can beat that cause it would be awesome!!!!

 

hehehehe! That is my car in the video.

 

I just found that they made Team Dynamics that might fit our car. I used to have a set on my SCCA civic and they were pretty nice and light for a non forged wheel.

They come in a 18x9 15mm offset as well as an 18x8 35mm offset, plus weigh between 21-24lbs. The only thing I don't know is what the center bore size is.
You may also be able to fit some 17x9s on there for 17" drag radials.

 

Bro nice run What was done to the SRT8? It sounds like it had a serious exhuast. Well i seriously recomend the Nitto's one of the best investments made so far. It looks like from the vid that you didn't launch that hard and still got an1.8 60', Bro imagine how much better that would be if you had the right tires on there
