Depends what you are trying to achieve. If you want lots of boost, then the way you have it is not going to work. The supercharger is controlling the engine air flow as it is a positive diaplacement device. All the turbo will do is unload the supercharger. For more boost you need to go turbo-supercharger-engine then boom! If you want the turbo to take over from the supercharger, then you will need something to switch from one to the other. Either way, you've made a positive start which is more than most have achieved. Well done. i was waiting for your reply :) having an actuator opening a ''flap'' to allow the turbo to have its own feed? off out to see what can be done..... On 2nd Oct, 2009 Vegard said:

i've done a fair bit of head scratching on this lately with my mate. He's got a supercharged KE70 corrolla that he's in the process of twin charging. We were planning on using some sort of throttle body and solenoid valve arrangement to divert the flow once the turbo is ready to take over.

well you could do it so that when the turbo makes say 6psi it could activate the actuator rod in the same way as a wastegate , but it'l just move the throttle spindle on the body,

has anyone seen under the bonnet of the 1.4gt golf, or is that likely to be electronically controlled as oppose to mechanical?
one day boost will be mine!

Either way, you've made a positive start which is more than most have achieved. Well done. As you chaps no; with modern boost control a compound charged engine isnt really nessicary, but on this situation we had no funds for decent ecus and external wastegates but had a s/c and t/c so gave it a go for a hell of it, which has been fun! which is what its all about i guess. As for the supercharger controlling airflow, it only does this while its doing its own part of the boosting. The way it works at the moment (as of tomorrow once ive prooved out this 2 port wastegate plan): - Supercharger boosts from idle - At about 4000rpm the turbo takes over - A 2 port actuator attached first to the outlet of the s/c and second to the inlet manifold opens when there is a highest pressure between the turbo/carb and engine than between the s/c and t/c. This is attached to and opens a throttle plate (from a vectra) which is T'ed into the pipe between the s/c and t/c and runs to atmosphere allowing the turbo to boost as normal and the s/c to vent and unload (but not restrict the turbo atall). Runs like a standard turbo sucking from the vectra throttle. -as soon as you lift off the bypass vectra throttle closes as the pressure is higher between the s/c and turbo than there is at the inlet manifold, at the same time the two dump valves open (as they would normally!). The supercharger can then boost through the turbo compressor keeping it spinning and on/ready to boost, and just vents through the dump valves (two dump valves as the supercharger moves so much air!) -as soon as you come back on throttle the dump valves will close (if needs be) supercharger loads up if the turbo isnt producing more boost etc etc. So thats how its going at the moment anyway! lol. We need to prove out this wastegate tomorrow, It should work though, when the supercharger is boosting the pressure should obviously be higher just after the s/c than at the inlet because of pressure loss through the turbo, on bends and through the IC. But running a bypass like this means we can run lots of boost :) even if we go turbo-supercharger-engine the supercharger would still limit it without a bypass device, just like the S4 which bypassed the supercharger at higher RPMs. Does sound awesome :) can hear the supercharger, then hear it unload, then hear the turbo boost, then loads of wasteing noises and such on lift off, absolutely mental, haha. Any info people might have on twinport wastegates and spring stiffnesses on them would be useful! Arron got hold of a renault 5 GT one im hoping will be good, fairly light spring rate.

As alex said the s4 used a bypass valve on the SC and high rpms, i found this diagram which shows this setup, might be of use to someone.

fascinated to see what happens on the rr,will it have enough bypass flow ,will it make small children cry ,and being rubi's ,will it smoke !!!
Medusa + injection = too much torque for the dyno ..https://youtu.be/qg5o0_tJxYM |

should have more than enough bypass flow, throttles about 50/60mm

Changed the Blitz barry valve for a bosch recurc one and the idle boost has now dropped to 0.04 bar once its warmed up which is all of 0.4 psi,

he wouldnt let me put 2 intercoolers on it :( settled with intercooler spray instead! seems to run ok. Lambda isnt calibrated yet, and ignitions retarded alot so if we give it any serious boost it just glows the manifold cherry red, made .98bar pulling into the unit the night before last! |
