I have a tial mvr 44mm wastegate and I want to run a base of 15psi and run the boost controller through hondata ... I have 7 springs In the box and have no idea which to use to have a base 15psi without touching the boost controller and running 25+ with the boost controller ...also there are 3 air ports on this wastegate how do I run the lines for the wastegate with pwm boost controll solenoid? Any help would be great thanks

 

What turbo are you running? Depending on turbo 15 psi base is going to blow the tires off and be useless if this is a street car. better off with smaller spring and using boost controller. IE i have a 9 psi spring in my car for 1 gear and then 11 psi in second gear and then 18 psi in 3-4 gears and my car hooks well other than 1st gear on the street.

 

It's a 6262 and its street/track but not much street not my daily .. I can't find a more detailed spring chart.. and what about the hook up of the ports? You've been pretty helpful lately man thanks a lot

If its mostly track and your going to be running slicks then i can see using the higher gate pressure spring.

if you purchased a real tial WG it should have documentation on the springs rates BUT here is a link to Tial for the spring information

port on the bottom are to the turbo and the one on the top goes to the boost solinoid. I believe the MVR has water jackets too but you dont HAVE to run those unless your road racing the car which generates tremendous heat in the turbo components

 

Well it Is a real one its from full race but it didn't come with a spring chart ... I thought the boost controller goes in between the fitting off the compressor housing of the turbo and a port on the wastegate?

 

you run a boost reference from the turbo to the bottom of the wastegate and you also tee off that boost reference to feed the boost control solinoid which then the other port on the solinoid goes to the top of the wastegate

 

Thank you Bro ... Do i put the plugs in the unused port on top and the 2 on the bottom? My mvr 44 has 3 air ports on the bottom of the diaphragm and 2 on the top cover above the diaphragm where the springs go ...

 

you can. sure, for a cleaner look and to avoid gunk inside in the future.

 

I'm not understanding how it would work properly if I didn't plug the holes not used ... How would the reference boost at the bottom push the gate open if it could bypass out another port?

 

plug the ports you aren't using. if you aren't using an ebc, leave the top port open.

 

Will do but can I ask why one port needs to be open on top?

 

So it sees only one boost source and not run the system closed loop. I'm sure TiAL will come on here to comment.

 

it doesn't if you are using an EBC, if you are not using an EBC leave at least one open, otherwise you create an 'air spring'

 

Ahhh ok thanks guys for the help its much appreciated
