I have a set of whites but I'd like higher flow ones if possible, to save messing about selling them and buying some more would anyone like to swap they're higher flow injectors for my whites? It's a long shot but worth a try :) Cheers Tom

[quote=T5Tom;497057]Why is it? You don't ask you don't get...[/quote] no pointless in getting higher flowing injectors, they won't make any difference, whites are enough

Ooh haha sorry mate I took it the wrong way! Were you running whites on the r?

[quote=T5Tom;497071]Ooh haha sorry mate I took it the wrong way! Were you running whites on the r?[/quote] whites come standard on v70r's but no i'm running blues, had greens but they didnt work, my 850r is running whites

So there would be no advantage to me running blues? Bearing in mind its my daily drive too and it drinks enough as it is!

[quote=T5Tom;497084]So there would be no advantage to me running blues? Bearing in mind its my daily drive too and it drinks enough as it is![/quote] no, wouldn't be any different, blues and whites are virtually the same

from what i can gather orange ,white are suited to the 850 because the fuel reg is only 3 bar so any bigger injectors wont make any difference i have blues in mine and it runs fine but the me7 engine they came out of runs higher fuel preasure so they flow no better than whites would

Frankie is right mate. Higher flow injectors won't make any difference. In fact it will use more fuel than it does now. The ecu will adjust the pulse width at part throttle to inject the correct amount of fuel 14.7:1 AFR. When in open loop (wide open throttle) your ecu cannot adjust pulse width and runs from preset mapping tables, so as the ecu still thinks you have the smaller injectors, it will add too much fuel. You only need higher flow injectors when your current ones cannot inject enough fuel for the amount of air entering the engine. Even stock oranges can fuel for 300bhp (just)

So I need a remmaped ecu more importantly?

If u have bigger turbo ie kkk k24 u will need greens or vxr blues plus a map other wise u will run lean and burn holes in ya pistons.......

[quote=T5Tom;497180]So I need a remmaped ecu more importantly?[/quote] Yes the ECU needs to be calibrated for the injectors you are using. You can get away with a small variation in injector size though. Why get bigger injectors though and go through all the hastle of a custom map when you can use stock injectors and get an off the shelf map?

which would you say was the best map? would a 304 be okor do you think i should be looking at a stage 2 maybe? im running a 19t atm.

[quote=T5Tom;497255]which would you say was the best map? would a 304 be okor do you think i should be looking at a stage 2 maybe? im running a 19t atm.[/quote] a 304 is for a 15g mate so really you need a better map to get the most out of your new turbo

i know Hamish has done quite a few 19t's before so sure he'll have a map for you

Post 497272 by T5Tom on 2012-05-11 14:49:16

Is Hamish from hlm?

Post 497275 by Dan850r on 2012-05-11 14:50:27

yeah
