toyotatom Posted August 7, 2006 Share Posted August 7, 2006 What are Siemens inectors like compared to Precision/Delphis? Im told the spray pattern on Delphis are awful and can make it hard for the idle to stabilise. Is there any truth in this? I have Precision 880s in an HKS fuel rail at the moment being run by an EMU. Should I upgrade or not? Link to comment Share on other sites More sharing options...

toyotatom Posted August 7, 2006 Author Share Posted August 7, 2006 So whats with the stories I hear from different people, not just on the supra board, who say the spray pattern on them is awful and as such causes problems? Link to comment Share on other sites More sharing options...
Chris Wilson Posted August 7, 2006 Share Posted August 7, 2006 I always check flow and pattern on ALL new injectors BEFORE using them in any performance application, that way you don't get any nasty surprises. Bosch, Siemens and Denso all seem fine, as a rule. RC Engineering have been terrible, in my experince. I won't use modded injectors at all, only ones MADE IN THE FIRST PLACE to flow X cc / min.
