Turbotech boost controllers

Heya,

found these and i am wondering if they are any different to a bleed valve?

Turbotech - Precision Manual Boost Controller

Don’t be fooled by inferior quality imitations- Install a Turbotech today!!

A mechanically engineered manual boost controller- engineered for:

Ø Faster spool up,

Ø Significantly reduced turbo lag

Ø Super smooth boost delivery,

Ø Virtually no boost spiking that cheaper mass produced items are notorious for

The Turbotech is installed inline between the turbo and the waste gate to fine tune the required amount of boost for your application. It is not uncommon to achieve performance gains equivalent to 10 horsepower per 1psi increase in boost levels. What does this mean for the quarter mile runner? For every 10hp increase in engine performance, 1/10 of a second can be sliced of your 1/4 mile time. Installing the Turbotech is the most effective and cheapest mod you can make to your car to achieve significant horse power gains- instantly!

Skylines, Lasers, Supras, 300ZXs, commodores, charades, 3000GTs, RX-7s, MR-2s, WRXs, PT Cruisers, EVOs, Celicas, Civics, Integras, you name it. If its got a turbo fitted, the Turbotech offers instant exhilaration!

Turbotech takes only 10-15 minutes to install and requires only a very limited set of tools. Even with no mechanical knowledge, the Turbotech is completely idiot proof to install. The unit comes with a complete set of clear instructions and diagram.

*PLEASE NOTE THAT THIS IS NOT JUST A BLEED VALVE – This is a quality engineered precision instrument for fine tuning boost pressure. Some backyard mechanics like to think that a bleed valve is a ‘boost control valve’, however, all a bleed valve does is restrict pressure flow. This is NOT controlling boost pressure as it is not a one way valve, a bleed valve allows pressure flow both ways and out to atmosphere. They allow back pressure which hinders fast spool up and causes excessive turbo lag because much of the unused pressure gets sucked back toward the turbo during negative boost and tries to slow down the turbine- much like having someone pulling on your shirt while trying to run. This problem creates what is known as TURBO LAG, a condition where bleed valves or mass produced and badly engineered boost controllers can’t control the boost, which can and will cause expensive damage to your engine- avoid this at all costs. Turbotech boost controllers are PURPOSE designed and individually BENCH TESTED prior to being sold.

The Turbotech with its high tensile spring and ball bearing design, is adjusted to increase your turbo’s performance, while greatly reducing turbo lag and achieving positive boost faster by faster spooling. Why is this unit different? The Turbotech is designed to prevent the turbo from back pressure and boost spiking. It does this two ways, after positive boost and driver backs off, the valve slams shut allowing zero pressure to back up and interfere with the re-spooling of the turbo. Any small amount of pressure then trapped between the Turbotech and the wastegate actuator is eliminated via a specifically sized ‘excess pressure valve’. Inferior boost controllers do NOT allow the venting of unused boost and thus causing BOOST SPIKING- ^^Expect SIGNIFICANT PERFORMANCE GAINS**

THE Turbotech is made from high grade stainless steel and brass. As air contains moisture (H20), poor quality boost controllers are made from materials such as tin or plain steel that will rust and corrode and will result in rapid deterioration of performance.

Note: It is highly recommended that a boost gauge and fuel/air gauge be used in conjunction with this product as excessive boost can cause severe engine damage. Turbotech take no responsibility for damage how so ever caused so please use common sense.

this is my understanding of how they work in the diagram below would you say this is correct?

and i am only after a cheap slight boost up to say 10psi so an electronic controller is out of the question. has anyone had any experience with these?

they are on ebay for $22.50 btw

Ok so no one has used on of these i guess... so would this be the same idea as the norgen valves?
