costs a lot tho

 

How expensive is a 3" V-Band kit normally? From what I saw your looking at $40 for 2 flanged and a clamp. McMaster is $10 cheaper then that.

 

ebay had them for around 30 bucks shipped a while back, thats with two flange and a clamp

 

god why are they so expensive

 

I got one of those ebay specials for $30 and the ****** leaks constantly. I dont really care though because its not too loud, and it jsut makes the turbine sound even more pleasant

 

Machine the flange faces down. Did you weld them with the clamp really tight? They may have warped if you didnt.

 

I actually picked up the piece from McMaster, seals great plus has a grove in it for a viton seal even if you want.

 

If they aren't clamped down before welding...you'll have fun getting them to seal. I welded my flange for my 60mm vband wastegate and the flange wouldn't slip into the wastegate afterwards. With a little convincing with a mallet it went on, but getting it off probably will be a blast. lol.

 

McMaster-Carr = $37.10:
3" flange t304: $9.36 x2
3" bolted (not t-bar) t304 clamp: $18.38

Personally, I'm sticking with racing-solutions. Don't forget your 5% forum discount + the shipping is always cheaper.
1 Stainless V-Band Clamp and 2 Mild Steel Sealing Flanges. Sale price: 95% of $35.00 = $33.25

 

-$7 for a wing nut clamp (vs. the 2 bolt clamp) and replace the wing nut with a spacer and a nut (which btw seals just as well and you spend $36.12 shipped... why pay Racing-Solutions inflated shipping charges. $14.00+ for a v-band assembly? you kidding me they could drop those in a USPS flat rate box and have them to you for $8 or just pay McMaster-Carr $4 shipping.
