Q:
I am building a 2.1 8v with lots of mods inc BVH, GS2H cam lightened crank,flywheel etc, i want to upgrade the injectors so that they dont become a weak link in my master plan.
Am i right that pb injectors flow 39hp each max, which limits me to 156hp. Im hoping for more hp, altho im hoping to win the euro lottery too
are all bosch injectors the same fittings,can i get some from a saab,cosworth, etc
A:
just saw the FAQ answered my own question,
is it just a matter of fitting them and thats it???
A:
Doesn't increasing the fuel pressure improve the std injectors?
A:
Aye, but only so far until they "lock up". Cossie injectors fit, and are dirt cheap on Ebay...
A:
Doesn't increasing the fuel pressure improve the std injectors?
Yes they can. Not recommened beyond 65 psi though. You can use an injector calculator to see how much the flow increases to and thus the max BHP each with the injector 100% open. Again the max duty cycle for these injectors should not pass 85%. So you must allow for this if you think your hardware is capable of max the OEM 0 280 150 757 injectors.
A:
On a stock digifant engine they run at around 80% max duty cycle. I don't know what the max bhp is but they run 180cc/min if that helps.
A:
ill look for some better ones, i prefer to underwork then and then they have a long happy life!!!
I could always try the RS2 injectors from the audi, they would be the same, wouldn't they????
