Injectors

[erny]

I am curious as to whether our injectors/fuel regulator etc are correct. Could someone tell me how long their injectors open for roughly at a couple of different parts of maps so i could compare with ours.

What are the general rules when picking injectors and regulator?

Cheers

First off are you running forced induction or naturally aspirated? The stock injectors/regulator will work fine for naturally aspirated but most definately won't work for a forced induction setup. There are formulae all over the internet for fuel injector sizing.
http://www.rceng.com/technical.htm this is the first thing I found on google.

We used stock injectors (2001 GSXR600) on our turbo setup and haven't even come close to maxing them out.

As far as a regulator goes, you'll have more than enough flow capacity with even the smallest regulator you can find. We used a Malpassi FPR from Kinsler. Have you set (or even checked) your base fuel pressure? The regulator you're using has a vacuum/boost reference (and you're using it), correct? What kind of ECU are you using?

The RC Engineering site gives you a good, quick basic look at injector sizing.
