Hey guys, I’ve searched and searched and still haven’t found the answer I need. Here’s the deal…
I’m building my own kit, I’m starting with a K26 (audi Turbo, very similar to a T3). I already just about about everything i need, except for the the some Fuel elements, (Injectors, FMU,…) I already a 255lph fuel pump(in Line). I’m planning on just putting the turbo on my stock motor, it has good miles and everything…only to run 6 or so PSIs
in the mean time I’ll be building the other motor i got, same as my stock one. My question is: How do go for figuring out the type of Fuel system I need?, I mean, I’m not too sure how to calculate the amount of Fuel pressure per Pound of boost, injector size and FMU ratio. The more I read, the more confused I’ve been getting!
I’m guessing if I used DSM 450s for injectors my FMU wouldn’t need to be such a high ratio, right? Is that correct?
Would it be easier then to get some smaller injectors and use a higher ratio FMU? considering they’re easier and more convenient to find and work with…
I already have an SAFC II, it just came in the other day, I’m planning on using to help me with tunning purposes, of course.
Thanks a lot for any help! I understand this is not one of the most “smartest” questions here…
