So the d15b7 injectors (235cc) are good for 180hp right? So I can round 5-7psi with a 14b turbo on stock injectors, correct?

 

180 whp
BSFC:0.60
Duty cycle: 0.90
Rail PSI: 50

294 cc/min

That is the "minimum standard" that I would go with. So round that to 310 cc/min. Leave yourself some headroom for more boost down the road.

I think stock psi on the fuel pump is around 43-47psi (and that's with a new pump). It's probably about 35-40psi at the moment.

I'm planning to get 450cc injectors since they are cheap but if it weren't for the price I'd try to get away with smallest possible and for the hp I wanted, 235cc would've done it. But even new 235cc are more expensive than the 450's so I'll just use those instead :-)

btw, where can I read more on fuel/liquid dynamics? I'd like to better understand the relationships between volume, psi, duty cycle, etc.

Thanks!

 

quick question:

On a 14b turbo with internal wastegate (say it's set at 10psi). Can I lengthen the flapper rod in order to get to 0psi on the wastegate, and then attach an MBC to increase boost pressure? Is that possible?

Thanks!

 

Anyone?
