[Mint FRST]

I'm running a hybrid, pace cooler and eventually a chip and actuator. I can only assume the fuel pressure has to raised.

Does any one Know the pressure it should be raised to?

I want and can do this myself at first but will eventually have a proper set up on some rollers - before those of you tell me I should do it that way!
Not to be rude!

Does anybody know what the fuel pressure should be tweaked to and base idle set to say on a car with an excellent and running 12 - 14 PSI

Anybody?

Forgot to say 'Excellent Engine'

Fuel pressure will not need to change much - your pump should be uprated through as the existing one won't be able to maintain pressure above a certain level of fuel consumption, although it should be ok up to around the 180bhp mark. The Esc Cos pump can be fitted with the standard regulator and will do the job fine.

Project is right, your fuelling might not be able to cope with the amount of boost especially as you have a hybrid turbo which shifts more air than a std.
Your safest bet is to wait and get it set-up properly. There is no magic fuel pressure number as every engine is different.

Do it properly first time and save yourself a blown up engine!

Fair enough chaps, thanks for the info.

Can some 1 explain to me how they 'set-up' the engine properly when carring out these mods? What varibles are changed to achieve perfection? Thanx.

When on a rolling road, the tuner can set-up your fuelling. This is done by using a gas analyzer from your exhaust. They will then make sure base idle is ok (doesnt break the MOT rules) and then they can run your car up (under load) and make sure your getting enough fuel coming through. They do this by watching the gas analyzer. Obviously if it goes too low they can turn up the fuel pressure, this will then give you more fuel going into the cylinder. They can also turn down the fuel pressure if your running too rich.

a rolling road is a harsh test for your car it will also show up any weak spots

I feel stupid but am i missing something?
How is the fuel pressure changed? ECU adjustments if u hav a chip? Do u need an adjustable fuel pump for the stage 1 or something?
How else can u get ur car set-up properly with-out rolling roading it?

The fuel pressure regulator on the injector rail of the FRST has a cap that can be drilled out to gain access to an adjustment screw, or you can waste money on an FSE boost valve.

However only adjust this is you really know what you are doing or you will most likely cause serious engine damage.

Is that what they do when they set-up the stage 1 chip on a RRd?
Who can set it up? Do i need a high pressure fuel pump?

OK The spec of my engine is stage 3 head, T2 cam, K&N panel filter, custom RS500 sized intercooler, T2 turbo running 12-13psi, Magnex exhaust and Superchips 165 chip. I had the chip installed boost set up and fueling set last year by Mike a RallyTec near me, but any decent tuner can do that job. Done necessarily go for the person with the biggest ad as the best prople do not need to advertise. I was recommended this guy by 2 seperate people and took my car back last month for a check over.

Parts not listed above are still standard and the bottom end and turbo have done 93,000 miles.

Will the PACE intercooler do the job for up to 14/15 psi?
So how do they set it up properly? Literally what do they do? Turn the fuel pressure dial, program the chip? CheeRS

[Quantum]

The Pace intercooler should be OK at that boost, but an ACT guage will help keep an eye on the temperatures. Go to Halfords and buy yourself the clock/thermometer with the externat sensor (which you dissaemble to just the thermister(sp?) and hang in the charge air flow.

As to exactly what the tuner does - pass as I trusted him completely, but basically the set the fueling and boost corectly, but I don't know in which order.
