Fuel Pump and Injectors Upgrade

[_turtle_]

Hey guys, just wondering if anyone knows the flow rate for our n/a injectors. And would upgrading to some GTS-T injectors and fuel pump make any difference except for running it a bit richer? Would you need an safc or something to make use of the upgrade injectors? I noticed at the dyno day all our n/a's were running quite lean.

Can pick up some injectors and pump for fairly cheap so just wondering.

the injectors can handle more then enough flow for ne possible mods u can do keeping the engine NA, an SAFC will help richen it up if thats what u want but keep in mind rich generally ='s less power.

Cheers

I disagree...my ones shit themselves pretty soon, when the turbo was put on, the pump was very limited too. I've got a 550hp pump and 385cc injectors now...they're well up to the job of extra power.

yes but 7psi boost is a big difference to ne perfomance mods that could be done whilst still keeping an engine NA. Maybe i worded it poorly but i said nething that can be done to the engine while still keeping it NA the injectors and pump would probabl;y handle it within reason. For eg, my pump is giving me ample fuel for an extra 75hp and is quite happy to do that but it would be a hell of alot of work to get an extra 75hp out of an NA engine without nitrous or turbo. Dunno if im making sense its too early in the morning but i think thats what i mean.

how many cc are the stock n/a injectors? i think what John is saying that, keeping the car n/a, any mods done to it will be handled by the stock injectors.

If you're talking exhaust, pod etc you should be fine, as you will only get a few hp...but if you're looking at increasing compression, getting the head ported polished etc...you may find leans spots. I'm really suprised that the nitrous hasn't leaned you out actually.

_turtle_ got what i was trying to say, big day at work just couldnt put the words together. Umm yeah no the nitrous doesnt lean it out at all, infact the car runs really rich with it, like the AF guage goes spastic and lights up every green bar it has. My boss says my injectors should cope with the rb30 block and huge headwork to the twincam head but i spose only time will tell.
