OK, installed a new NW's CAI (dual) and Magnaflow Cat back exhaust at the same time - seems quite a bit faster (not that it was by any means slow to begin with). Maybe a smaller pulley in the spring - anyone have advice in that regard???


thanks,

Which "smaller" pulley ?
I assume crankshaft - any other would be counter-productive.

 

Going with a smaller SC pulley is the norm, George. The crank pulleys are the ones that are larger in diameter than stock...and cost a heck of a lot more than the SC pulleys. Seeing as how no one sells one smaller than 65mm anymore, Eurocharged is your only real choice.

 

Thanks Chuk, once again my N/A brain failed to grasp that he might be talking about an SRT6, nothing really stated which.

 

I started with a 65mm supercharger pulley and currently have an ASP 178 crankshaft pulley on my car. The beauty of the supercharger pulley is the ease of installation. After doing it once, it can be done in under 1/2 hour. The 178 crank pulley makes a little more power than the 65mm S/C pulley. The downside is the installation. To get the pulley torqued correctly you need a 4 ft. bar and tool to keep crankshaft from rotating. I did mine on a lift. It took me holding the tool with an extension bar and a second person with the torque wrench up to spec. and then 4ft. extension for the extra 90º you have to turn the NEW crankshaft pulley bolt.

I,m having a brain fart, how would a smaller crank pully be more productive on an NA?

 

It would spin the alternator, water pump, PS pump and AC compressor slower, thus freeing up more HP at the crank ( in theory )

 

Seeing as how this is posted in the SRT-6 subforum and he's asking about pulleys after adding a DCAI, it's a safe bet he's talking about an SRT-6 supercharger or crank pulley...lol. That's why you don't see me posting in the coupe subforum.

 

And then you can check the user gallery. Beautiful grey SRT roadster. Your blessed!

Agreed Chuk, I was just answering his question :
