I just ordered the new aluminum code 3 pulley from Brandon, but then
I saw all this talk about different sizes here on the forum - sm, med, and large?

I didnt specify any size when I ordered and he didnt ask - Is this "for real"?
anyone got some precise measurements on these in comparison to stock pulley?

I have an email out to Brandon, but if anyone can shed some light, do tell :-)
Are there really 3 sizes to choose from, or is it just different manufactured
batches that turned out to be different sizes?

Best,

Grant

 

They make larger SC pulleys for people who have enlarged the drive pulley (say to 178mm) so that they can get more boost

 

LIKE JEFF SAID CODE 3 MAKES THE MIDSIZE S/C PULLEY TO GO WITH THE 178MM CRANK PULLEY, AND ONE SIZE S/C PULLEY FOR ANYBODY THAT HAS THE STOCK CRANK PULLEY. ILLCYA

 

thanks Guys - reading through some of the other posts, it kind of sounded like people were saying there were diff size pulleys from code 3 for the same application - I just got an email back from Brandon at Code3 confirming what you two told me - thanks for the help

"There are two sizes that we sell. There is the smallest size, which is what you are receiving. It was designed to make the same/more power than the standard 178mm crank pulley upgrade. Then there is a mid sized pulley we sell as well. It was designed to be used in conjunction with a 178mm pulley (dual pulley setup)." - Code3

 

Just for the record, the idea of the mid-sized pulley is so that when combined with the 178mm crank pulley it doesn't overdrive the supercharger past the spec'd rpm limits. If you combine the smaller Code3 pulley with a 178 crank pulley it will overdrive the supercharger when the engine is at peak rpms.

 

Hey Grant, when you get your package and get ready to install your pulley, send me a message. I'd be happy to give you a hand and then compare the two cars with our different setups. Just let me know.

 

Thanks a ton for the offer to help - I just saw your message right now after returning back from the install at Mahdavi Motorsports in Lilburn - great guys there btw - I was in and out in an hour.

Raining like cats and dogs today so couldnt really push the car, but what I did notice right off was how much harder it pulls from 2k rpm - really a big diff there.

Supposed to be sunny tomorrow so Im looking to go do some un-safe driving aound atlanta tomorrow - can meet up - can pm me, but i wont miss the message if you use my contact form
