do you need one of these if you're running bigger injectors (550cc) and a 044?

Bai suggested Iget one to raise base fuel pressure to 3KG, as it will assist in making the car more responsive.

Also, if you have Sard 550cc injectors, they are rated at 550cc at 3.05kg, at stock pressure 2.55kg, they are around 510cc. they also have a bit more lag than the stock injectors, I have +0.08ms correction for mine and they run sweet, but this is at 2.55kg - havent upped the pressure yet:) soon.

I have just fitted a rising rate reg to my RB30.... a fuel injector 'cleaner guy' was out today fixing a Leaky injector I had and was shocked at my fuel pressure...apparently 100kpa at idle...!

He bypass'd the reg and got it down to 50Kpa, where it ran smoother...

What pressure should it run at idle?

    • It just occurred to me. The way I am asking for increasing bite as I slow down (ie more bite the more time on the brakes), that is actually sounding like less initial bite, and hence the bite would feel to increase.

    • Actually I need to book the V37 for a test day, who is running it? And yeah just let me know if you are down night before or after and we can kill some beers That is my super power
    • Sorry, I must've not been clear enough. On my 350GT, the pads originally on the car created dust to high heaven, and did not squeal at any time. I got new low dust pads, that created absolutely NO visible dust, that squealed when cold.  It wasn't  the initial bite, so much as an increase in braking, without extra brake pedal pressure, during a single brake instance. I had to lift off a little as my speed decreased to zero. Loved it! Now on my 370GT, I have to press a little harder as I approach zero. Not hard, just harder. I am too lazy and live in a city block with no room or tools to do it myself, so I would be paying someone to do the switch I looked at the three offerings by Intima, and one of them had a Features line that caught my eye. "Strong initial bite with continual rising coefficient". The problem is that this is on their "Trackday, Time Attack, Sprint" pads, not their day-to-day pads. Its possible that JAX installed track day pads on my 350GT, I just don't know. But I was pretty clear I did not track the car and drove the streets pretty gently. https://intimabrakes.com.au/home-corporate/intima-rr/ I'll send them an email and also check if other pads purport that behaviour.
