Best Waste Gate For A T51 R Hks,

[campbell]

well first stage of tunning was carried out today, but apparently my 50mm trust wastegate is to small can anyone recommend somthing they have used on a hks t51r. what size or brand would be the best to use..

we only got 590 rear wheel hp on pump fuel no noz.

[BU5TER]

at what boost?

[campbell]

1 bar....

[BU5TER]

Whats wrong with that, seems pretty good to me

whats one bar 14psi? Seems like very high power for the boost with what I've seen from T51r's on RB26 and RB30's

EDIT: any chance of a dyno sheet?

I would have thought it pretty hard to have too small a wastegate on a T51? They would use a fair bit of exhaust energy...what made them think the wastegate is too small?

Hell, plumb that airlfow through the enfine rather then dumping it through the wastegate and problem solved

[R31Nismoid]

If the gate is running out, use more boost so it has to dump less.

I second buster on the graph

[campbell]

yea its not to bad the turbo isnt even using peak power at 9000 just keeps climbing they did somthing with the cam timing to level it out but the wastegate is to small apparently no of a good size to go with the t51

50mm should be fine, run a bit more boost and see what happens.

you could always just stick another wastegate on for good measure.

the Tial 44m are a very good unit!

[FATGTS-R]

What exact problem are they having they say the gate is too small?

How is the wastegate pipe plumbed in? Custom manifold? off the shelf item?

Mate has a 1000hp turbonetics turbo using a 35mm turbosmart gate and its fine.

With the solenoid off and running straight off the spring which is 16psi its been no drama.

The HKS kits use a 60mm GT wastegate, although that is pretty massive. What's the problem - not holding boost? Boost spiking? Boost bleeding off?

[Dragster33]

How about a graph or is it to bad to post? hahaha

[Morgs]

There is no graph?

[campbell]

the problem is the boost is still climbing so maybe their is a hole in the diaphram i tried reversing the solinoid it went straight to 2 bar ...

i no its not to bad with the 100 hp shot of nitros through the direct injection should bring it up around 700 but yea its not bad out of a rb25.....

[NathR32]

590rwhp?....I'm keen to see this dyno graph.

[S3_Girl]

absolute bullshit

[51OWW]

You'd wanna hope you got 590hp you crazy bastard haha.

His engine
