Punishment Racing Tial 38mm MVS Wastegate Install

[DSM_ThuNDeR]

I bought a pakage deal a couple of weeks ago from punishment racing. It seems that the MV-S vband 38mm wastegate is new for 2009, so there isn't really accurate proper installation diagrams/pics that I have found (ONLY FOR F38).

Talon/Eclipse Tial MVS 38mm Wastegate / Recirculated o2 Housing Package

I have took out the flapper, and ported the hell out of the whole. I installed it just this weekend, but decided to go WOT just today. According to P. Racing, this wastegate comes with a 1.0 bar (14.50 PSI) But when I got on it, my boost gauge reads 20-21PSI! This wastegate has three ports on the bottom, one on the side of the top, and ONE ON TOP. Where exactly can I tap my boost source to this wastegate with my MBC? If anyone has purchased it and has installed it, please post up some pics and a little info too. The Post that Punishment Racing has here promoting this wastegate isn't really useful on the count that they said they were going to post some installed pix of the gate, but NOTHING

I am really confused. I hooked up the gate T'd off at the BOV running straight(No MBC) to one of the three bottom ports, top side port is blocked off, and top is left to vent to the atmosphere.

Well thanks in advanced.

You need to plug 2 of the bottom holes and run the line to the last one. Leave the top one vented.

How do you have it hooked up now.

BLANK PIC of the wastegate for you guys to draw and show me how to hook it up:

I will be really happy if I got this dam thing to work. Another thing where exactly can I put my MBC?



I forgot to mention, I do have another vaccum nipple for the wastegate that came with the pakage but did not install that one.

Can you share where you bought those plugs for the rest of the holes you blocked off?

I ran mine without them plugged and had a hard time controlling my boost but I'm wondering if this was the reason why.

The Tial MSV comes with those plugs. All lower ports (except for the one you're using) need to be plugged, otherwise the wastegate will not properly function.


DSM_ThuNDeR - You really should pop the top off of that wastegate to verify which spring it really has. Otherwise, you're only guessing how much boost you're supposed to be running. I wouldn't trust what it was 'claimed' to have came with, because it's easily possible that it has something other than what you think is in there. Also, your really should shorten up that vacuum line to the wastegate. Run that line from the manifold directly to the BOV only. Then run a separate line from the turbo's compressor cover or lower IC pipe directly to the lower port of the wastegate.

Is it currently spiking, creeping, or just running high? Did you do any porting on the volute of the turbine housing?

youve got so many miles of vacuum hose that it wouldn't matter if youve got a 10psi spring in that external wastegate... jk
alright heres what Paul is talking about. you need a boost source as close to the compressor of that 20g as you can get. that way as soon as you go into boost that tial will see it and open up ASAP to control it.

in the lime F&F green is the routing of my vacuum lines for my wg and my bov. i have mine actually zip tied to my radiator, not floating around in space by the exhaust mani but hopefully you get the idea. if you don't have anything to hook up a hose to on your licp what alot of guys do is screw a nipple into one of the couplers instead of going through the trouble of welding one on a pipe. just do a BLT after the install!
hopefully we were able to help?
