Just emailed back and forth with Jake at eurocharged and he put the srt6 pulley (64.7mm) on sale for the holidays for $498! Thats $130 off! If your interested!

 

Looks like its time to pull the trigger...

 

Anyone want mine 64.7 mm? Batch 2 from EC. ONLY 10 miles. Pm me.

 

Actually both sizes are on sale for $475. Not bad at all...

 

You are correct the 61mm and 64.7mm for $475!! Even further discounted is saving you $155...Merry Christmas everyone!

 

Have you any pictures available to show...how much to ship to Toronto Ontario Canada

 

A question, what is the actual size in mm of the OEM supercharger Pulley?

 

74,0 mm ....................

 

I'll save you even more! Buy my almost brand new (less than 500 miles on it) 64.7 EC 2nd gen. pulley for $430., and save $200. It is in perfect shape and I have zero issues w/ it. This is the pulley for those that want the power, but w/o the need to upgrade their fuel system. PM me if you're interested.

 

EC says no need to upgrade fuel system for the 61 mm one.

 

You can believe that if you want.

 

FYI, One size does not fit all when it comes to fueling and boost. One guy's 185 may run fat on a stock pump, while another guy's car is lean on just a 181. It's always best to have a wideband and know for a fact that you're not lean. Just my 2 cents.

 

If tailpipe black = fat?

 

What if it's fat until 5K, then leans out after that to 16 to 1? My point is, soot on the pipes confirms it's fat at some point, that's all. Just food for thought.

 

Absolutely! Could not have been said more clearely. Don't make the mistake the whole RPM range is rich (fat), unless you can afford it (engine). This much I do know.

 

I love working with the guys at EC'd....but, like mentioned above. If you are running modified mani's, dual cold air...going to 61mm may run you lean.... I don't even see why anyone would want to run the 61 if they weren't intending to do these other mods including fuel... There aren't shortcuts here... one mod leads to another and if you aren't building that way...go with the larger pulley...stay in the safe range, or be willing to monitor your engine... I am sure if you discuss this with anyone at EC for your tune, they will explain it as well...

 

Am I to presume the pulley is a good idea if your racing but not a good idea if you like to travel with the car?

 

Thanks for replies. Prior to purchase i asked them (jerry) regarding running lean and they said no problem for me, just need a re-tune.
My mods:

Cm30
Supercooler waldig
Isolation kit
Catchcan
Psk for SC (updated)
64.7mm (today)
Dcai x3m filters
Ec tune 98 octane, elevation (low), limiter off

easiest way to monitor this? Can it be done at a local dyno after I installed + ec tune, and then they check that I am in the clear?
Second option, buy new fuelpump?

 

This is what i asked:

Hi EC! Hope all is well. Just a short question, will the car cope with following setup:

1 dcai (x3m)
1 psk
1 waldig supercooler
Ec ecu tune

And ...
A 61mm EC sc pulley?
I have the 64.7 mm today. Will I need to upgrade other things? Fuel pump? Intercooler? Or can I swap it and everything will be a o kay? What about running lean.

Answer I got:

Philip - An updated ECU tune would be required, but that's it.
