Ive been told the calibra turbo injectors are no good for throttle bodies and can lose upto 15bhp.. Ive spoken to a couple of tuners SBD and QED both suggest changing them to Webber injectors.
Problem is they are 300 quid and im like most people dont have a clue whether they r feeding me shit or not..
Any thoughts?

an injector is an injector, once maxed out its maxed out...? fuelling will become a problem when your running them near to their max output...

im guessing LET injectors are good for a tad more than 200bhp...?

id hazzard a guess at spray pattern being the kinda 'squirt'

i.e is it like powerwasher, or a garden sprinkler... direct or mist.... dunno to be honest

Think Lee mitchell knows about the injectors and spray patterns because the xe's can have two types of injestors with different patterns

nope but the spray pattern, on a turbo engine i guess that they would spray a lot of fuel in one go when the turbo spools, or the engine would run lean,

im sure turbo ones are more of a squirt and n/a are a mist

I have already changed from cream's to the yellow's ( Calibra Turbo ) the fueling aint a problem now and duty cycle is good at 75% but i just wondering if these tuners are saying you will lose upto 15bhp coz ur running turbo injectors due to there spray pattern then i guess changing them to the webbers is a good idea but i dont know if they are just saying that to get some extra

Only thing i can think of as regards to the spray pattern is that in the LET's the fuel is squirted in , which is then vapourised by the hot compressed air. Could have been that if they sprayed in a mist of air, they get more chance of detonation, as the fuel is already vapourised when it enters the chamber.

Thats about the only thing i can think of anyway .
