R 5 GT Turbo Adjustable Boost

[neutral 3]

Anyone have an in car adjustable boost fitted ? I need to know the layout of the pipe work from the boost control into the engine bay .

Boost feed > Controller In > Controller out > Actuator.

Be careful, if you dont fuel for the boost you'll blow it up. There cars have a rep for Head Gaskets, which I find undeserved, it's usually ignorant owners that cause HG issues.

Hi Dave , thanks for reply , do you have a photo ? My turbo isn't working, only 1 pipe from the in car boost control is connected !

T piece with restrictor, restrictor has to go turbo sideof the pipework and then pipe heads off into car to controller (cooker knob size thing normally) the back out of the controller and to atmosphere

In that case you'll have a pipe from the pressure feed/boost pipe straight to the actuator with a T-Piece in the middle. The T will feed off to the In-Car controller.

very much so. I run 20psi and my fueling is spot on

Re-reading that, if you have no boost at all you have a different problem. If the boost control system was goosed you'd have at least actuator-base boost pressure, if not unlimited engine death boost.

If you have no boost, either you have a leak in the induction system, or the turbo isn't working/producing pressure.

Still can't figure out the problem. I have checked the turbo and it isn't seized, but i just havnt got the time to play about at the mo.
This is the first heavily modded ( K- Tec ) 5 that I have owned . Anyone local to me in essex who could have a look ?

join rtoc.org mate they will help you.

The pipe work is pretty straight forward.

Lobster should have pipe to actuator with boost controller somewhere between.

make sure pipes to intercooler are all fitted and no leaks etc and it should boost

what spec is the car?

most of ktecs stuff is actually just standard i.e pistons/liners

All you need for big power is

2 1/2 inch down pipe and side exit.
285 cam
bigger intercooler pace one is ok if you cba for FMIC
t28/gt28r set to 20+psi

easily over 200bhp get some pics up as well!
