About .7 bar mate.
Wouldn't really want to go any higher then that without having mappable management put on
Edit- that will be why my mate can't find any ecu maps that quote torque figures in ft/lb for his s60 R

Already got an exhaust mani.
I wonder where i should get the extra fuel, the fuel Line that goes Into the fuel rail, and split it to the 2-4 other injectors on the elbow, or how people do?
and with the oil cooling, is relocation kit with a oil cooler the best option?

If ppl were not running a proper management, and just adding injectors
They ignition can't really be played with
So it's just left, that's the reason you can't really go more then 7-8psi
I've seen ppl use 10psi and have no probs, but that was on a vtr which runs a lightly lower compression ratio as standard

you can use a raising rate fpr, they are big in the usa when supercharging big blocks etc. basically they raise the fuel pressure in relation to the rate of boost. so as boost increases as does the fuel pressure ;D. they come in a load of different ratios etc, google them and have a look if your not wanting to run management, google FMU fpr fuel managment unit. never heard anyone using one on a saxo, i have seen them used on a honda s2000, i was going to go down that route a while back.

I answer myself, 1,5mm i std , repair gasket is 0,4mm thicker = 1,9mm.
Getting an 1,9mm instead of std gasket would lower the compression to about Kollar
10,35 instead of 10,8.
So i wont lower the compression that much.
And then skim the head, so it doesnt lower much, and im not changing pistons etc, not on this car i won't.
Im still not sure if i should buy the predator ecu or not, 500£ seems abit much atm (ithink its a good price, for PnP tho, but the car went for 700£ smth).
About how much was the std injectors good for, 160 hp, and they maxed out?
