Whats a good external wastegate to go with?...making to much boost with my a5000.

 

Tial makes a good one, going to have to weld it to cast iron, though, which takes some skill

 

what size would be the best you think? thanks

 

The Tial gates are Ok for us but they don't like the heat we produce...... Also the cycles they last before a rebuild can be crazy. I have one at the house but I forgot the manufactorer. Darn thing will take 2200*+ and is good for over a million cycles. Best part is if/when it needs a rebuild it only needs a ring. The one I have is a 50mm and is billet. I will check the brand and post.

right on bro thaks....

 

Anxiously awaiting your reply Doug. Im in the market for one too

 

i would look into a Turbonetics wastegate or an HKS, they both can handle the heat and give u rock solid boost, they are a little pricey but well worth it

 

My 38mm Tial is still in one piece....the body is made of special stainless steel and the vent side is Aluminum Alloy. The diaphragm is the only week link but it is easily replaced...If the wastegate melts out....the pistons are probably already gone. I ran mine up to 1700....the tial lasted longer than the inconel valves...if there is a better wastegate....I'm always interested.

I think you can just machine and tap a manifold to take a wastegate. Ask Olee at power by poole....ks

 

Sorry about the delay.... Here is a link to the wastegate I was referring too: http://www.jgstools.com/turbo/index2.html

 

Yep, I like it....my Tial would always leak above 50psi....the 2" vband connections make removal a snap...If it was good to 120psi...I'd be very happy. ks

 

I've got a few of those laying around . They are massive compared to their 40mm though. The race trucks I'm building will use those.

 

there is a 60mm Tial unit that can handle extreme temps, well over 2200 degrees
