I just bought a PT51 turbo and told the guy i was using a stock downpipe. Well the puck on the stock elbow is WAY to small to cover the wastegate hole. What do I do to remedy this. I want to use my stock ported elbow as it has a fender dump on it. Thanks

Where do I get a larger puck and is it easy to install?

Why don't you send it back and tell them they sent you one for a THDP instead of a stock size puck?

Call them first, Obviously.

Sounds like you bought it used and someone aleady ported the wastegate hole. I bought mine new from PTE and I use a stock elbow and it works fine.


You can contact Mike Smith as I know he was doing ported stock elbows with THDP Pucks in them.

I believe they would be willing to swap it out. When I bought mine I specifically asked them not to port it out. I have since upgraded to a THDP and it is still working great with the stock sized hole.

I also have PT51 with THDP.. when i ordered it from MM, I told them to port it out for the THDP. Works great. Spool is slow off the line because I still have the stock TC. a nice 9.5 vigilante 3000 should take care of it.

Hold on!

You have a 51, a ported, stock elbow and a fender dump. How long will it be before you wish you had a larger hole and puck?

Maybe you're attacking the wrong problem?

I gave up on it. I'm getting a THDP instead and i'll just run it open from there. Jack Cotton explained why the fender dump won't work with the stock DP installed also. Basically becomes a big restriction due to air being pulled back thru the exh. and mixed w/ehx. from the turbo going thru the relatively small fender dump. Thanks for all your ideas and help.

Darn, worked for years and now it does not work! Well, at any rate, it really was no big benefit from my experience. That Jack is a salesman huh?
