Dickhead!
No #### if it is going back to the inlet as I said obviously it isn't still compressed!
Wanker

firstly whats the point of this ####ty PM to me! u shy about saying things upfront, or u expect me to b afraid or what...hehehe.

secondly u r TOTALLY wrong about what u r saying, learn or zip your lips.

We are talking BOV ( i know I am! are you?)

Air has to go in the inlet of the turbo ( the compressor )
then through the engine then through the exhaust manifold to the turbine wheel then out the exhaust!

a turbo has 2 wheels, one TURBINE second COMPRESSOR, extra air from BOV goes DIRECTLY INTO THE TURBINE WHEEL not compressor wheel. Einstein.
and it does not get re-compressed it goes out via exhaust.

when manifold pressure goes above 5 psi the fuel pressure goes straight up to 14 psi.I


can u tell me from which car u have taken out the fuel pump? is it EFI or carb setup?
does the extra fuel goes back into fuel tank or not(loop)?
i have read that any normal fuel regulator can b made adjustable fewe modifications. what do u think of this?

But if you compress something it will get hot!
Yes when it is relaesed it will cool abit! but it isn't like a gas changing to vapour ( all it is doing is going from compressed air then to atmospheric pressure!) It has not really changed state a great deal! so there is no way it could be as cool as fresh air!

i said same thing thats why i gave an example of a water pouring on a HOT engine, but u cant just accept that u were wrong at the first place. and now u r rephrasing what i have already mentioned

Quote:

And if you take this air which has already absorbed heat and then compress it again it is going to create more heat!

u making no sense here!!
this air is going to get out via exhaust as soon as it passes the turbine wheel(as their will b vacuum in the turbine wheel), what makes u think it will b compressed again!!!!
i ask advice for what i dont know, that does not mean that i have to listen to whatever u say, wrong or right.
cool it bro......

Barpk we all agree that it is lower than the exhaust temp in the turbine wheel!
but the thing is when you compress air it generates heat and by feeding this compressed air straight back into the inlet it will be compressed again and will generate more heat!
That's all he means!

simply put u dont know what u r talking about!
when the compressed air is sent to urbine wheel via a vacuum hose it will b decompressed due to the vacuum in the manifold, thus lowering the temperaturen which is already lower then the turbine wheel temperature. thus it will having a cooloing effect. period.
heat is a relative term, boiling water is a very hot thing but if u pour it on a maximum hot engine it will still make it cooler.

sounds good for emmisions but must increase intake temp quite a bit

it lowers the temp! cos the air from BOV is not exhaust but fresh air. which is certainly low in temperature then of the turbine wheel.

one more benefit of BOV: -
if we use a Loop BOV(first used in 911 turbo) in a turbo, what happens in normal BOV is that the excess pressure from BOV is released into atmosphere, while in a loop setup, the excess pressure is redirected into the intake of turbo 's Turbine, which keeps it spooling and reduces back pressure even further, increases throttle response and improves lag
my 2 cents
and does anyone of u knows what turbo is present in a Starlet IC Turbo motor?

i like when people gets pissed off, but u people r all i have to come to, so guys b cool, i am a rookie, but not that illinformed as i look, main prob is that i have only one engine to work upon, and that car is used every day by other members of my family too, so i dont want to take much risks, but i will turbocharge my A12 that i know.
regarding fuel pumps, i have concluded that on my carby setup its not possible to get away with mechanical or non EFI electrical pump, i have to get a EFI elect. pump for 20 PSI or so. but i cant get a regulator here in PK, so what do u guys suggest i do?
can it be made in a workshop somehow?
can i build a homemade loop system around carb whose PSI can b controlled from dashboard of the car according to boost PSI?
anyother options?

But on our standard carbies ( boosted )
We have the fuel pressure set to 6 psi and the needle and seat handle it ok!
( Standard it is 1.5 - 2 psi)
This might mean nothing to you guys but its just a fact I thought you might like to know!

what u meant by "(boosted)" u mean its a turbo charged 1200? how much do u think needle and seat can handle? 20 PSI!!

what the hell does that mean? which one is right stuff? or botth r fine.
BTW how do i make a alcohol injection? can it b done without any pressurized can?
what about windscreen water sprayer?
what about using a Spray Paint nozzle?
