injectors for a t28 powered dc4

Sorry, I didn't know he was your man.

..and stop being a tool.

[AusS2000]

OK. What sort of HP are we talking about? What PSI and what A/R? And what is an acceptable duty cycle?

[AusS2000]

I'll stop being a tool when you start backing up your claims. As your 'boy' says, you've stated 3 times that 440s are enough. Enough for what? Enough for how much? The whole secretive, "I know better than you and don't have to explain myself" attitude is a tad arrogant.

IMNSHO 440s are not enough. At least they are not enough to run the sort of Hp I would expect with a safe A/R and reasonable pressure and duty cycle (my calcs are on page 1). And even if they do scrape in it is shortsighted to spec the minimum requirement.

So rather than just repeating yourself why don't you share with us the specs that lead you to believe 440s are enough. Or do we just take your word for it?

Well said aus2000.

I see it better to explain why to people rather than assume things and maybe lead them in the wrong direction and cost them an engine. I recommend that you do your research and come up with your own answer as to what size to run, don't just go off one mans word, or his "bitchs" word.

Cheers.

Us tools gotta stick together.

something like 440ccs would be ok, but honeslty the price different between 440s and 750s on average is close to nothing. IMO i would go much larger due to the fact you will always have room for improvment and you will not have to pay too much more.

[DynoDave]

i'd go 550cc from rx7 series 4, better to have headroom than none. what if later on you want more boost??? buy new injectors again? when it comes to fuel systems i like to over kill to make sure i never run out and dont have to worry about upgrades again.

Is this from first hand knowledge or something you have read on the net.Rotary injectors have a very bad spray pattern as they come from a 2 stroke style engine where heavy droplets of fuel are requied.And these droplets really do not burn very well in a Honda or any other street driven piston engine.

first hand my friend. i have personally fitting them to a honda b4 and had no problems. i've also used them in a number of other 4, 6 , and 8 cylinder cars. i have also seen there spray patten up against xxx brand and seen no difference. We all have our own opinions on how things "should" be done. They have worked for me and other people over here without any problems.
Regards Andrew.

but to get back on track, i stand by my opinion and say 550cc wheather they are from a rotor or not for a setup running a T28BB.

[yourfather]

if you know so much about these Rotary injectors, wouldn't you understand different method of combustion process means different requirements for fuel injection, therefore you are completely disregarding what people like DynoDave has to say.

He's probabyl been building engines longer than you've been breathing.

Might as well start up your own forum where you spread your own disinformation.

But yeah, 550cc from RC Engineering are ok for you.

[terroristone]

read my post again dude. im not disregarding anything. i am saying that i have used them and not had a problem. there is also no need to speculate who or what i am, because for all you know i might be alot older than you think. It seems that i have been "protrayed" as another internet know all, that is not the case at all, i have proven to my customers and myself that these injectors work...i am not here to argue that x is better than y. if y works for you and x for me i dont see it as being any problem just because one person anounces themselves as being in the "trade" it still dosnt make them right. As i said let him do his research, take into account "everybodys opinion" and make his own mind up. Is it such a problem that 2 peoples opinions confict even when they get the same result? the way to getting that edge on the next guy is called "trial and error", if you listen you are only following, use your brain and try something different and if it works then you are making your own path to success. I think that starting my own thread will defeat the purpose of him asking his question. He wants peoples opinions and that is what he is getting...it upto him to decide, im not telling him go get 550cc, he can make that choice for himself after reading everbodys response and the crap that goes with it.
Regards Andrew.

[AusS2000]

There is definitely some argument to the spray pattern thing, but not being familiar with RX injectors I couldn't say whether or not they are suitable. I do know that RC Eng injectors used to have a less than stellar spray pattern but the newer ones are optimised for a 4-stroke otto cycle engine with direct port injection.

The turbo is a t28 non bb if that helps

AUS2000 - I dont give a **** if you think i'm arogant, but for this kind of turbo you would not be looking at over 200whp.

I still stand by my original comment, 440's will be fine. If you can source them cheap, go for it, otherwise 550's will be more than enough.
