Title: Fuel presure.
Post by: TonyC on September 24, 2007, 09:59:16 PM
What base line presure should I set the regulator to for a single turbo car, running standard primaries and 1600 secondary injectors?
I\'ve no idea what the standard car would be set at.

The regulator is a rising rate, hooked up to vacumn, so I need to know what to set up as the base, before manifold presure alters the fuel presure.

Thanks.

Hi Tony,

42psi will do you. Hows it going, Anyway. Will you be coming down to Santa Pod for Japshow?

Cheers, mine is ploding on (as you can see in my lonely lonely thread ;) )
Off work all this week to try and move things on a bit.

Sorry, won\'t be coming down to the Pod. I will probably be working, but even if I am not (and sorry to all fans in advance) I wouldn\'t come becuase I just find drag racing really really dull. It was nice to meet the other MRC guys at Rotastock but the stuff on track did nothing for me (except make me a bit more deaf)

Carl set mine to 35psi, I was having problems with it set at 42psi.  It should have a vacuum pipe that will cause the rate to increase.

With the 550 primaries, set it up at 42psi. :Thumbs-up
