guys will siemens injectors 55lbs be able to flow enough fuel for 270/280bhp on a 1600cvh fitted with gotech and stage 3 t34 .48 (nms spec) as a friend has a set to cheap to say no realy

thanks

 

well they do 400bhp plus on a cossie so i would say they would be fine mate

 

wicked my mates got them and im getting them for £100 and my greens and hes never started the car up with them fitted lol

 

55lbs is 577.5cc so they might be ok, you cant compare it to using them on a cossie as the BSFC is totally different, the CVH requires loads more fuel to make the same power.

 

thats cool karlos ,i didnt kniw that ,what size injectors do you have in your own mate?

 

I have Siemens Deka IV's 630cc, they are at about 65% IIRC making 231bhp.

 

630cc DEKA IV's are the ones to go for IMO, not the cheapest, but around £200 inc tax etc you can get them from the states and will flow around 125bhp a piece on a good BSFC, more than likely 75-80bhp per injector @3BAR on an rst though.

 

£150 if you tick the box for them to be sent as a gift lol

 

Karlos can you PM me the company you got yours from? these are the one of the next things on my list to buy.

Rob,

 

Of course mate!

 

Thanks buddy

 

so the deka's are bigger than the siemens black's but are they bigger than greys as any of them will work with my ecu but i just dont want to run my injectors flat out so im looking for something that will run 270bhp and run that safely.

cheers

 

greys will piss that power on a cvh, we are running 300ish hp on them in a cvh no probs.

 

well greys it is anyone fancy a deal on a set of greens

 

greens as in 803's ? they will do 270 on a good spec cvh but not a lot more but still safe.

 

i was just wondering as im going t34 stage3 .48 and my engine is stage3 head piper fast road cam/ low comp 1600 woszners/steel rods/ worked crank/gotech mfi/greens/ airtech manifold-fmic-rad-breather- and custom down pipe but im getting a nice manifold and inlet once saved up

the guy i brought the turbo off was running greens at 289bhp but with a better cam but the greens where maxed

 

erm...yeah
£40 bloody quid to customs, even ticking gift doesn't mean you'll always get away with it sadly though

 

i get all my stuff sent as a commercial sample,never get stung.

 

Greys are around 600cc and as Gary said will do what you want with ease, I was running them but they were too noisey being low impedance so went for the Deka's which are much cheaper brand new, high impedance, and have a better flow pattern, they are an all round win!

 

wicked guys well its coming apart again this weekend and having my new bits fitted ...

im fitting a cts box with atb ect and vibratec gearbox mounts and t34 and down pipe and ive got a monster air filter aswel... and i will just take a set of greys with me when i get it mapped and then if they are needed then they can be fitted.

then if someone buys my turbo quick i can get those 6pot brakes

 

Greys are 503cc at 3 bar of pressure, so smaller than both the Siemens 55s and the Siemens Deka 60s.

 

Thats their official rating yes, but they have regularly been known to flow aroud 600cc when tested.

 

i was wondering that but there are plenty rst's runing high 200's with them and some over 300bhp
