Just looking to see if anyone is running one and what did you get it turned down to. Correct me if I am wrong but isn't the C3 65mm? Anyone running smaller than that? I think we have had similiar discussions on here before but could find and not sure where it lead. The stocker being steel should hold its form better without warping at the mill, if it is cooled properly. I guess I am just looking for some opinions and/or experience with a s/c pulley other than C3.

Steve, thanks for looking out for a replacement.

 

c3 is 65mm. i beleive tvt will turn down the oem to 63mm. you might check some of the speed shops in huntsville.
if i locate a c3 i will let you know

 

155 / 74 = (2.10) * 5.8K = 12,180 SC RPM (Factory)

178 / 74 = (2.41) * 6K = 14,460 SC RPM

181 / 74 = (2.45) * 6K = 14,700 SC RPM

185 / 74 = (2.50) * 6K = 15,000 SC RPM


155 / 65 = (2.38) * 6K = 14,280 SC RPM

155 / 64 = (2.42) * 6K = 14,520 SC RPM

155 / 63 = (2.46) * 6K = 14,760 SC RPM

I might go with the stocker turned down to 64mm. It would be closer to or just better than 178, . I have yet to confirm that TVT will do this but I need to get the funds together first. I need to find some things to sell, for this was not on the list of things to do, lol.

 

Just doing some nerd math here....

Looks like based on the above calculations you gain:


- 81.65 SC RPM for every one (1) millimeter you increase the size of the crank pulley.

- 172.16 SC RPM for every one (1) millimeter you decrease the size of the supercharger pulley


Just some random information that could help those guys thinking about turning down their sotck SC pullies to run stacked.

 

Maybe TVT would like to jump in here and update us on there experiences with the turned down pullies. It may spark some business being as the C3's seem to be so elusive and expensive these days.

It is nice that our stockers are steel, for as I found out, aluminum vs a 6,000lbs press..... well that is another thread, .

 

You may want to contact TVT direct, as the last I heard they had been banned from this forum .........

 

I'm an NA guy but have been talking to TVT and practically live on their site.

They just put the machined pulley on their site for the SRT6.

 

I see they have that pulley on their web site now, and though I've been a
fan of TVT for sometime (have a few mods bought from them) I'd have to
say that $375 is rather steep to take a part and grind a little of the metal
off. And, if you want to go smaller than 69mm, you'll need a new bearging
as well (price for this is not listed).

 

I know a few of his customers that have gotten it and it's basically the cost of what the machine shop charges. They had to make a tool for it so they need to recoup the cost.

I think they mentioned the bearing is for safety reasons. I know they have a guy running much smaller with no issues, but better safe then sorry I guess.

Maybe one day I'll have a SRT to try it on.

 

I've been looking for a C3, but having the stock pulley machined down to whatever size I want does sound appealing. Not for $375 though, considering the extra cost for shipping and the fact that you don't actually get a part out of the deal. I'd rather spend the extra $$$ for a C3.

Good find though. I did not know TVT was still doing business due to their banned status here.

 

Wow, Where have I been? I had to do some searching for the banned TVT thread but just WOW. I, for one, will not be swayed by this occurrance. Anthony has helped me out by answering questions and giving suggestions to save me money, and I muchly appreciate it. That is all and I don't want this to turn into a TVT for or against thread. I will post up results, thanks for playing, lol.

 

I'm sure there's nothing wrong with TVT, and after reading the thread I thought it sounded a tad childish that he got banned anyway. I just wanted to point out that not a lot of people knew he/they were still in business. I have been messaging him about making TVT tubes for the SL 55 intake, and would probably have the stock pulley machined down if it didn't cost so much.

Who has a C3 they want to sell!

 

Yea they are still in business and going strong. I know they started doing their oen custom tuning and have begun on more suspension pieces.

I'll be getting the entire adjustable rear suspension, TVT250, custom ecu tune, and SRT6 exhaust very very soon.

 

My note was not to disparage TVT in any way, shape or form. I've been
quite happy with the parts I've purchased from them, and thought the price
for those was quite fair. I just don't see where it would be cost effective
to buy a new OEM pulley (at retail price), then pay an additional $375 to
have someone mount it on a metal lathe and trim it down. And I have to
assume, as I didn't see any mention on the web page, that there would be
an additional cost if I wanted to go lower than 69mm and had to purchase
a new bearing. Just not in my ballpark when I've already got a code3 that
is already smaller (original batch).

Anthony, in my opinion, is a stand up guy, I really have found his service,
and TVT components to A#1.

 

Without getting into the base cost, why would you have to buy a new OEM pulley? I'm sure you could find some takers for a direct swap: code-3 for OEM.

 

I already have a stock pulley, and the installed Code3. I would want to use
a brand new pulley as I want to keep the option open for returning the
system to stock by re-applying the stock pulley. If I send off my stock pulley and have it turned, I won't have this option (unless I buy a new
pulley) .

 

yeah, I meant that you could keep your OEM and trade your c3 for another OEM (likely plus cash), then have that OEM ground down

 

Can you even buy a stock pulley? I thought it wasn't sold seperate from the SC.

 

I guess I'm just a pack-rat. I just can't see a reason to sell or trade the
C3. If the shave pulley from TVT should have any problem, I'll want the
C3 around. I know, I know... I just can't seem to let anything go. The
more SC pulley's the better

Hmmm, that could present a problem, for me. I would not want to do any
changes to my stock pulley without having a OEM replacement handy. So,
if one cannot get the pulley without buying a new SC, then this would not
be a solution for me.
