Bugeye injector query
 

What is the max bhp you can get out of standard bugeye WRX injectors?

Would 440's from a classic fit?

Thanks.:thumb:

classic injectors are different - they are side feed (yours are top feed)

You can get just over 300 bhp with the std 420cc injectors in yours.

Would that require a uprated pump? Or is the standard one up to the job?

I'd put an uprated fuel pump on. Just for piece of mind buddy.

Got an uprated fuel pump (Walbro):)

I thought bugeye WRX injectors where 350cc ?

No idea, i'm going to be fitting sti pinks very soon, think theyy are 550's

Found out off some geezer called Andy Forrest, he said theyre 380cc and can take up to 300 bhp.

Apparently I should listen to what he says :) :P

Not wanting to dispute what andy is saying but they are scaled at 420cc in all the standard wrx maps.

You can squeeze a bit more flow from them by running at a higher fuel pressure, good for times when you are almost at the limit, as my "pinks" are currently...

dunx

P.S. Fuelab @ 4 bar static.

Good stuff, so if I want around 300bhp with a TD05-16g on, I could leave the standard injectors on and use a FPR?

yes

but it would be cheaper to find some second hand 550's
