redline pulse duration
 

Does anyone happen to know off the top of their head what the redline pulse duration is for stock NA injectors at redline and or 7k rpm and or the formula and or a site where I can glean such nice knowlede? Thanks.

Not sure, I think you need a injector pulse gauge to find out.

I think you're right after searching around a while and readin some stuff.

I will see if I can find a link I had for one

that would be sweet! thanks.

Damit, I cant find the link, ehh it wasnt that good anyway, it showed you how to make a homemade one. I searched for about a hour and cant find anything on the net for a fuel injector duration gauge/meter odd.... Why do you want to know anyway??? Im sure they are not maxed out yet. All I know is you dont want to go anymore then 80% of the duty cycle, but I think you should be able to pull 7k without a problem as long as your mostly stock/not boosted

I'm not boosted yet :) I'm just trying to figure out the logistics of maintaining the stock injectors and running boost, I doubt i'll bump my redline up to 7k though with the boost, that would kinda be askin for it. I've been talkin to rberry951 about building a chip for the car after I get the turbo installed and he is pretty sure that we can stick with the stock injectors, which would be nice, but i fear that i'd have to run an unholy amount of fuel pressure and that would ultimately be bad for my fuel pump. So I was just tryin to get some real numbers to crunch and figure out what the logistics were with respect to timing and all. Thanks for the effort though.

Might wanna try to upgrade to a 951 fuel pump thats what Im gonna do for my nitrous kit. SHould flow what you need without a problem, How much boost you gonna run???? Depend on how much boost will determin what size fuel injectors you need, I would think the stockers would be good for about 250hp so about 6-8psi boost and you might not have to run super high fuel psi, proly around 50psi at idle or so

I didn't know the 951 fuel pump was capable of more pressure. Makes sense I guess. I'm planning on 9-10psi of boost. I think it would be cheaper to upgrade the injectors with a used set off of ebay or the junkyard than to get the 951 fuel pump. Since I'm getting a custom chip made for the car I'm sure as long as the impedance is the same the chip can be tailored to the injectors. I can get a descent set of 36 or 42lb injectors for under $50 if I watch what I'm doing. If I get 42# I'll have more future potential (to break things).

What kind of boost does a stock 951 run?

as far as I have seen about 10-12psi

That's what it runs in my mind.
