first YO..sorry i hijacked your thread and took it in a bad direction




lol..Mark

just because i dont agree with you doenst mean i dont respect you or you opinions..it just means i dont agree just like you dont agree with me......

cutlassefi

No problem. I'm confident you'll learn something different once you start tuning on it. THEN we can have a conversation.

young olds

I know there are different injectors out there but do they all fit in the same hole(injector bung)? Or do I need to pick the style injector I will be using and find bungs to match?

young olds

Also, mark, can the accel use both high and low impedance injectors or just one? If just one which one?

cutlassefi

It'll use either one. The main difference in injectors is the o-ring to O-ring dimension. You'll need that before you weld in your fuel rail stansions.

young olds

So basically the "height" of the injector is the only difference?

young olds

whats your guys thoughts on duty cycle?

cutlassefi

85%. Use the smallest inj possible with the highest pressure. It'll drive better that way.

marxjunk

theres at least 100 calculators out there to chose the right injector as far as flow rate etc..the guys over at yellow bullet like this

oops double posted the same link heres the one i meant

and its the one i just realize Mark posted below

young olds

Would you go any higher than 85 percent?

cutlassefi

90 maaaaybe. But that's it.

young olds

Been looking at injectors and I noticed for a given rating in lbs the cc rating varies seemingly quite a bit. Should I pick based simply off the lbs rating, cc or both?

distributorguy

If there is a discrepancy between lbs and cc's, someone has their numbers wrong.
Smallest injector possible, staying under 90% duty cycle at max output.

cutlassefi

No, I believe you're wrong. Multiply lbs by 10.5 to get cc.

I have to say you have me wondering just how much you really know about this stuff, or at the very least, your ability to convey the facts.
Just sayin.
