T3-T34 is it really worth it?

Fair point Mike.
I should have put
Appropriate modern injectors with a suitable flow rate / spray pattern / impedance and that are the correct physical fitment for the inlet and the rail
I thought that was implicit but better to make it explicit
Thanks for pointing out the inadequecy of my description.
The point being made though, that 803s arent ideal for 400bhp+ was and of course still is perfectly valid though obviously!

), it's just that I have seen several engine's on Harvey's dyno that have had the correct impedence and flow rate injector, but due to the pattern being like a narrow "beam" (obviously designed for applications where the injector is some way from the inlet valves), once they have gone above a certain (low) duty cycle they have peaked and no further increase in injector on time has resulted in there being any increase in fuel getting into the engine..... I was just pointing out that Cossies don't like these type of injectors (which is NOT obvious from your post ).And 803s are perfect for even 500+bhp (providing you have enough of them
). However, I have never seen a set of four 803s produce any more than the 385bhp I have quoted - and given that they were absolutely maxed out, I can't see anyone being so stupid as to go beyond this with them LOL.

Mike, you didnt mention impedance or flowrate, I did though as those are equally important, and if we are being thorough we should cover those too 
400bhp+ is perfectly possible on 4 803s if you start upping the pressure but its nasty and I wouldnt recomend it, but its certainly possible.
