the 620 still makes 292bhp at the wheel's for

2.5 year's and for a engine that cost's Ł600

what wheel bhp has your escort got for Ł600
it's a cheap car and i can surprise a few people
in it ,every one know's when you go down the
road in the escort and don't bother with you
[saying that i have,nt been out in the cossy for 2 mouth's ]

In your fucking DREAMS . Greys run out of fuel at 440bhp (unless you mean 8 of them ) .

To achieve 500bhp at 7k on a 2 litre Cossie engine, you would need a T4 size turbo, and sufficient fuel (8 greens or 4 x 750cc injectors) and 30-32 psi depending on headwork / cam choice.

What CC's are Grey injectors rated at then?

i will be running 660cc at 5 bar the engine mapper

said this is enought [siemens disc injector]

my cam's are one off billet's made to cossy profile

they had load's off lift i had to machine the bucket's

to a bigger diameter

Dan,
Just over 500cc at 3.5 bar.

Wilky,
That is a hell of a lot of pressure to be running at, you sure the fuel pump is up to that and won't cavitate ?

Personally, I would use a high flow pump and run it at a lower pressure....

mike thank's for that i have got a uprated pump

i think it's a walbro i find out what the capacity it flow's

will any body know on here if i find out the number's on the side

of the pump

Wilky,
You need to check that the pump is okay to run at that pressure, because don't forget that with a rising rate regulator, it will have to run at 7 bar (with 2 bar of boost) and it may shit it's load at that....

sound's like i'am going to get in a lot of trouble.
i hope i don't have to make another fuel rail
an siemise my injector just made that lot last week

i think the mapper said it's 5 bar at full boost total
i have to find out

i need to run a remote fuel reg .do you know of a good
one to use as i have herd bad thing's about some after
market fuel reg's

thank's for any info mate

The standard Cossie one is very good and is cheap as chips. Will run at 3.5 bar static fuel pressure all day long (which means it sees 5.7-5.8 bar on big power engines) . Avoid the FSE ones .
