Which Injectors

[mrxd]

Are there any massive problems if you use a larger injector than required for your power output?

[JETURBO]

Yes injectors need to be selected on power goals but the window is large

[mrxd]

Ta, what would the implications of a large injector running at a low duty cycle be?

[JETURBO]

A larger injector at low duty cycle has poor atomization chacteristics, this then leads to hot spots in the combustion chamber because the fuel pools out of the injector vs mist out

Also rough idle, worse economy and a harsh reving engine

Dont use a fire hose to water a daisy ......

Look no wikipedia and no hands lol

My ID1000's run 46% max duty cycle on PULP...no issues. Modern injectors with multiple hole director / diffuser plates (and the ID style for that matter) don't suffer the problems of the past....consequently massive injectors are very precise at idle pulsewidths / extremely low duty cycle. So these days there is no issue using a firehose to water a daisy. Most tuners are recommending ID1000's for 300kw cars when a 52lb EV14 will suffice.

Edit ill also add that my ID1000's idle at 1.27% whereas the deka's 60's idle at 1.13% at idle. Funny how the injector with a larger flow rate has a high duty cycle at idle! I've explained this in some of my older injector post.

But it'll kill the daisy :(

Somebody think of the daisy's !!!

Thanks for dropping the knowledge bombs gents. I have some brand new Bosch EV14 1000cc I got for a good price. Was a bit concerned they might be overkill for stock FG huffer, cat and cooler.
