340bhp- can i use 440cc injectors
 

340bhp- can i use 440cc injectors on a 03 bug eye wrx?

Cheers again!:notworthy

Not according to Andy Forrest`s site

Yes, a 16g can make that figure with supporting mods.

The one shown on the link doesn't look like a genuine unit though.

A mate was running a 2ltr @330bhp on 440's with an afpr, mapped by AF.

Cheers again boss:)

440cc injectors are at their theoretical limit at 350bhp. You can turn the pressure up a bit but I think that youd be better getting larger injectors and letting them work less.

:) cheers

I know a fella who got 356bhp/355lbft torque on a 16g with supporting mods, car ran a 12.5 quarter mile as well....and all on standard internals too:eek: ....oh and did i mention it has 150,000 miles on the clock and still going strong:eek2:

:)

wow.....150,000!!!!!

Nope.........I ran 320 ish on an Andy Forrest Front Entry TD05 16G on my Bugeye but it needed Sti injectors and a few other mods.

cheers again.

i still fail to see how people can get 350BHP out of one of these when some 20G`s only get 370/380BHP

As above: make sure it's a genuine 16G and some bigger injectors would be advisable to get the best results. You should also put the STi 8 intercooler in the car.

Well 350 is a nice target. I'm aiming to see what a 16G will max out at once mine is back on the road and mapped up again. If it won't make it on the build I'll have put together, which will have every supporting mod possible inc. ported and polished STi4 heads, forged bottom end, Hybrid FMIC and plenty of fuel and air, then no 16G can make it LOL

for 340 bhp can i get away with 440cc injectors and std wrx intercooler rather than sti??
Or will these scupper my chances of getting max bhp
Cheers

Different rolling roads = different figures maybe, i've got a 20g on mine and its 370bhp/405lbs.ft @ powerstation and may see 400bhp on another set of rollers (acording to Andy Forrest), even the rolling road opperator @ powerstation (fuzz) told me that at that power their rolling road was approx 20bhp down on power engineering's rollers, who's are most accurate???

440 injectors and WRX intercooler will struggle to get over 280 BHP IMHO :D

Shaun

what about 500cc injectors and sti intercooler with td05 16g (and f)

You'd probably just do a quick headline figure before the intercooler gave up, really for over 300 that WRX intercooler is no good for more than a few seconds at a time and the injectors are borderline at standard pressure. With an adjustable regulator you could get them comfortably up to 350bhp capability at say 3.5 or 4 bar fuel pressure. Depends on your future plans whether a new reg is something you've got in mind anyway, or whether bigger injectors are a better option for you. Or both.

even if a 16g could get to 350 ish bhp, it would be past its max efficiency rate. If Andyfs website says it cant then I would tend to go with what he says

agreed ;)

A mate ran 330bhp 0n 440's with an afpr, and i ran 330bhp on a wrx intercooler.

cheers again folks

IIRC from the compressor map a 16G is comfortable (i.e. peak efficiency) at 1.0-1.1 bar.
