Why not just run air injectors Phil???

Dave Henshall

this can set up manually and very acurately. whereas the air injecotrs would need mapping in with the ecu, and re ajustment is then also not as easy. this can be run through to the inside of the car to give in cabin ajsustment as per the pic a couiple above.

Dave,

I'm affraid I only advise the use of mapped amal/air injectors as it prevents the user from altering the boost himself. People being the way they are often can't help themsleves in adjusting the boost, especially if they have in car adjusters, and thats why I really don't advise any in car form of adjustment, UNLESS its a properly mapped in car adjustment such as for air injector control.

Anything that gives the user adjustment is recipe for disaster. After you car has been mapped and setup, it should not be adjusted without seeking advice from your tuner!

(This advice is given after all the years of hearing "I only tweaked the bleed vlave a bit, honest")

Dave Henshall

i know exactly what you mean - but on my car i use it for dropping the boost if its going into a garage for anytihgn etc. i know what can happen when the tweaky finger get involved.

In all fairness Karl whilst YOU dont agree with them its up to the individual!!!!After all if they do turn the boost up to far and melt then its more business for the tuners You should be recommending them..LOL

Karl

Phil,

However it works the other way too.

When folk are stupid enough to turn their boost up, they still blame the last person who set it up!!!

nice one dave

now where's that company account number.....

foreigneRS

one question dave.

do you find the length of hose required to mount the adjuster in the dash slows the response of the wastegate down any?

Sorry, but i cant help but think of this:

Phil.

Dont spose you have a spare set of air injectors do you?? Just need the actual injectors, not the rest.

Dave Henshall

i dont have it run into my dash, you could though, ive kept my lines as short as posssble and have my regs mouted inbetween the cam belt cover and slamp panel, so the total length of pipe runs is not more than the original to the lectron valve and t piece.

Switch

so whats the benefit of fitting a system like the above diagram, over an amal valve?

Dave Henshall

easily ajustable and you can ajust how forcefully the boost comes in.

foreigneRS

downside - ecu cannot reduce boost under any circumstances (too high ACT's etc)

Dave Henshall

true, and it cant limit the boost in LOS,

with the boost im running (and once my new secs monitor is installed) i can monitro charge temps with alarms and theoretically with the chargecooler/intercooler, it shouldnt exceed the shut down point.

Ive used this adjustable system for several seasons , in fact i Bought Phils when he advertised it as it was Cheap compared to what they ususally are. I previously had a bleed valve in the car which came with it ,it blew out at Snetterton costing me a 3rd place and wasn't best pleased, this new system is very adjustable , very accurate and very simple . It did however tempt me to " tweek the boost " down the straight to clear back markers which did lead to high ACT's , but a bigger intercooler will sort that for this car. As long as you are sensible it works very well , the car was responsive and it allowed for changing conditions , like a damp track . RS components are very easy to deal with , i hold stock of most of the Norgren 6 mm Pipe ends to make these kits up now.

Cheers for putting that info up Dave!! very much appreciated!!. I think Im going to have a pop at making one of those, just for a bit of fun (and also as my amal seems a bit knackered!!!



Cheers,

Simply not true , I buy loads direct from RS.
Takes two minutes to get it sorted as a private account.

ps. Farnell OK as well buy bits from them also.

FAO Dave Henshall, ya said you would put up acouple of pics??? would really appreciate it

Dave Henshall

good point,, i was under the bonnet yesterday aswell, will do some asap, promise

GARETH T

MADRod, thansk mate,,, i know before you needed a trade account, i dont pay for anything i order though radio spares or farnell

Switch

CheeRS Dave will look forward to the Pics

the original

so what method of boost control would you use with s8 if money was no object and you wanted a safe set-up?

ImaRacing 700

Depending on turbo mate!

Air injectors aint safe if they fail as you get max boost

Escos amal like me i guess although i am still on testing

RANJ

eboost

GARETH T

what a thing to say though,, its like saying,, a fuel pump aint safe if it fails

ImaRacing 700

Gareth.......my heart is also not safe if it fails..ROFL

Switch

Ranj u say turbo smart e-boost. i have heard electronic boost controllers struggle with high boost applications, hows the turbo smart? I know someone who had an apexi and over 24 psi it was a bit unpredictable

RANJ

high boost is no probs with eboost, rod runs 2.5bar, with near 700 od bhp.
sunny has bought and sold on many electronic controllers and so far has found this to be the best for te job in his case.

yum360 also uses this (2.4bar) i wil be using this, mark also uses on his 550hp evo aswell

Dave Henshall

here are the pics installed on my car, it is quite neat (apart drom the long bolt that need cutting down - i know) and the lenghts of pipe run are minimal.

good controller indeed ranj. Who supplies em and how much for the 40 psi version?

foreigneRS

looks good dave. do the adjusters lock off (like you have to lift them to adjust them or something) so that they can't change with vibration?

Dave Henshall

YEP - AS YOU SAY, YOU PUSH THEM DOWN AND THEY LOCK - AND HAVE TO GIV ETHEMA GOOD CLICK UP TO UNLOCK THEM.

Switch

looks good have been looking a a few of these mechanical boost controllers, including turbo smarts gated ones:

http://www.turbosmart.com.au/boost_c...lves_gated.htm or

http://www.boostcontroller.com/index...6category%3D13

why would your sytem be better than these? I know with these you cant dial in things like a spike, but can u with yours?

Dave Henshall

that second one is v similar to the dawes device boost control i was usin on my evo 6.

Switch

yep have been looking at the dawes device too. would love to have a chat to ya about what u thought of them?? and how they compare to your current setup

Dave Henshall

the dawes device was cheap, (i had the "race" version which had a lighter ball bearing inside, allegedly made it spool up faster, but when you think about it, nothing other than a change in the design of the turbo could actually do this, never mind the boost controller. it is v simple to fit v small, buti had it stick open a couple of times and had to take it to bits to free it off and re build it (only a 20 second job mind) it would hold 1.5 bar of boost fairl well, but there is only a fixed bleed hole in the top to allowhow fast it is allowed to build boost before it controls,

the beuty of the 2 valve system is that it allows the rate of boost increase and the max boot level to be both ajusted , indipendantly of each other.

my car is off the road at the moment so haven't actually tested it in anger and does need puttin on the rollers for a good run up/down the revs and boost to check that the chip is fuelling for the boost that is dialed in on the regs.

Rick

Dave, i understand how ur system works. From what i can see, the first valve will not open untill a certain pressure, preventing creep. I have done a few variations in plumbing on my car, and find that with a -34 i get no creep at all.

From what i can see, it doesnt allow u to alter the spike. This is purely a function of wastegate response time?

Switch

, rick, r u running this kinda boost controller too? am in 2 minds whether to try this kinda damwes device type or try Daves setup. mmmmm am not after in car adjustment but a ease of setting up
