turbos

[cypriot_boy_2k7]

what electricals are involved on them?

[Karan]

no electricals on the turbo itself

only other electricals depends on what management system u wanna use, or retain stock...

[cypriot_boy_2k7]

so if i leave it standad will i need anything

[Karan]

yes u will need a remap of your existing ecu and a rising rate fuel pressure regulator

[cypriot_boy_2k7]

rising rate fuel pressure regulator? can u explain

[Jon_Bmw]

Erm without being harsh. I think you need to read a bit before you ask some straight forward questions as you may understand the responses.

Putting one used turbo in the boot doesn't stack up to 50bhp I'm afraid.

[maxfield]

With a turbo the car will need extra fuel.

So it ups the fuel pressure therefore you get more fuel.

whats that meant to mean??

so its a bigger pump correct

[Jon_Bmw]

[maxfield]

No, it's not.

[march109]

have you read anything about turbos? or the threads here on turbos? its coming across as though you haven't bothered to even do the basic homework and we can give you the questions to everything you ask (as we have above) but you won't anderstand the answers until you do some reading for yourself.

Use the search function, enough on the Zone to be getting on with.

Also Google has plenty of answers!

rising rate fuel pressure regulator, that's like an actuator

[maxfield]

I thought actuators transfered an electrical current into something physical?

A rising fuel pressure regulator will increase the pressure fuel goes into the injectors. So for ever PSI of boost from the turbo, the fuel pressure will go up 1 PSI.

[march109]

nope because an actuator is a device which creates rotary or linear mechanical energy.

surprisingly a rising fuel pressure regulator, increases the fuel pressure when the turbo is on boost so the engine can make use of the extra air in the cylinders by adding more fuel to burn.

the standard e30 fuel pressure regulator is set at a fixed pressure because as standard an e30 isn't turbo'd and doesn't need the fuel pressure to change.

its not hard to use the search function!

Maximium Boost by Corky Bell, great book and you will learn everything you need .

[cypriot_boy_2k7]

wow rudeness Cheers for that oldroydsr4 will give it ago

^ good book

the stock FRP( rebulator) will remove 1 psi of fuel; for every psi under atmospheric pressure, so in effect will function almost as a pump jet on a carb on rapid throttle changes.

using the stock FPR you'd get 1:1 rising rate, so 3 bar stock pressure + boost( 10 psi) = (14.7x3)+ 10 = 54.1 psi

using a Rising rate unit ( various avail, we'll use 8:1 here ) 3Bar + 10 psi of boost would see an effective fuel presure of 44.1psi + (8x10psi) = 124.1 psi or 8.4 bar, under atmospheric pressure(vacuum) or off boist the function remains 1:1 are per the OE unit.

there are 1: up to 12:1 units out there BTW, and the stock pump wont supply the required pressure for the RRFPR to be effective, the injectors will also struggle to open due to the pressure head on the pintles.

RRFPR as the only method is a bad call, a standlone or piggyback is required/ heavily recommended.

RRFPR's are covered in detail within the Corky Bell Bibles, read, absorb, read more then decide.

check out the TCD website in the US too, the offwer a chip and RRFPR combo to suit M20/30/50 series motors, all use bigger injectors than stock though....

my uncle lent me this book and even i could understand it.....sort of

no electrical connections on an actuator. mechanical device using a spring and a diaphragm i think?

[cypriot_boy_2k7]

there are a few types of actuators, because my mate had a rs turbo and wouldnt stop going on about it, and at work we have to fix/ replace you get electrical and mechanical to types

[Karan]

actuator in general terms is just a remote unit that moves/controls something else, usually a flap/spindle etc etc...

in turbo talk, its just something that when triggered (on reaching a certain preset bopost pressure) opens the turbo wastegate which bypasses air from the cylinders past the turbo and out the exhaust, thus preventing going over ure desired boost

in my limited cosworth experience ive only ever come across mechanical types.

[foggy50361]

My experience with actuators and early turbo's are they come with a pneumatic actuators i.e. Use turbo pressure to work on a sprung diaphragm to open the bypass valve and limit how much pressure delivered, the use of electric actuators with newer turbo applications is misleading, the method of limiting the delivered pressure remains the same but the use of an electrically operated bleed valve to allow controlled performance of the boost pressure i.e. Limiting the amount of boost in first and second gear or allowing a limp mode if the ECU detects a fault like detonation
