We have these coming out of production pretty quick. T4 and T6 versions both available. We will be having a group purchase for the first 10 of these to get an idea of how well they will sell. You must use these with a divided housing!

Pricing with a group purchase would come in at 399$ for the T4 and 409$ for the T6 versions.

So would there be interest?

nodrok

where do you find more info?
Any dyno results?
Is there a HP limit on the set up?
Does a divided flange effect peak performance? How is it controlled?
Does it come with everything needed to hook it up?

Sorry I know these questions are annoying, but you know there coming. I would like to see how much HP I can net for $400 in the lower power curve.
Thanks

Look up Zombie. he has done extensive testing on his rearmount (and thinks its worth every penny)

You can get divided housings for almost every turbo out today. Half of the housing is blocked, and as you come into boost, it will progressively open relative to the boost you are building. Its like haveing an adjustable AR on your housing

We have seen over 100+ ftlb gain in our test car with an 88mm s400 / iron block 370.

Pricing is 20% less than competitors.

It comes exactly as shown, just run a vacuum line to a boost reference.

We have yet to hit a "horsepower limit". That would be a function of your turbo.

i built one for my car. it is unbelievable how fast my car spools. sure makes it interesting when i race cars with nitrous.

buick_lsx

at what psi does it beging to crack open, and what psi is it fully open? or is it adjustable?

Motovative

Its adjustable based on the length of the arm off the actuator

Yup, took a gamble when I saw it. Just glad I knew a good fabricator to install it and get it working

After having one, I'd still pay $400-500 for one. Big difference in performance. If I installed an air solenoid to hold the valve shut until around 10psi the car would be damn near undrivable. In cool weather I have boost before the gas peddle hits the floor. Track launches are 3300 rpms and 6psi on the 2 step to cut low 1.5 high 1.4's with 2.75 gears with a 3850lb race weight.

Motivate, those look like mild steel based off the rust, mine is stainless and was much cheaper. $400 would be a decent price for stainless.

I agree with zombie. If the main flange is mild steel, this is a very bad idea. It's not even a cost issue. Exhaust systems condensate internally during cool down and the valve is very near contact with the flange when closed (shut off car cooling down). All you need is for the car to sit for 3 wks while on vacation and rust itself closed. Mild steel is fine for non moving or constantly lubricated parts. For a part that is always moving and is not lubricated, 304 is the minimum grade of material to use, with preference to 316.

I'll tell you from experience in using spool valves in a front mount....you better test them thoroughly and make sure they dont begin to stick or gall up. I've had so many problems I am looking for a smaller exhaust a/r turbo to avoid needing it. I actuate mine with 80 psi of nitrous and a air actuator.

With the TH400 did you change your converter any? I think you could probably tighten up your converter to help with efficiency as you'd be spooling quicker.

How do they perform on smaller engines, any info or links ? ( ie 4cyl turbos )

We are just in the preliminary stages of testing. Needless to say, its exactly the same as the version that Sound Performance make, just more affordable.

Stainless or mild steel?

dudeman

ya, when i had the guy build my converter i told him my setup and he said he would make it a little tighter to get a faster spool. it seems to be working well!

They are Nickel Plated mild steel (same weather resistance as stainless). They have bronze wear bushings to prevent gauling, and I think we are the only ones on the market using a fully sealed shaft design.

Do you have any pics of one installed.

dyno results! we want graphs!
