Modest are we?

To the guy above. Those extra injectors and rail allow a second set injectors to be used instead of having a larger set of low impedance injectors. Improves drivability and idle when low impedance ones would be otherwise required.

What the light ball said.

 

I'm not here to pick on the manifold and the fuel design of it, but side-by-side injectors in a 4 valve engine would provide a better pattern and thus, better fuel atomization than front and rear injectors.

 

already ordered man.
but with my power goal I'm going to need more fuel then the stock PCM can supply on it's own, so 8 injectors should cover me til I run out of things to do to the car lol

 

Actually, I was going to mention that. Area47 uses my fueling tables. Marcin Pohl and I actually confirmed that the method does work. We can't really verify for sure that it works impeccably past the 63.5 mark, but I am in the process of working on a way to prove it for sure. If my testing works out, you will be able to switch from 42s to 60s without ever having to change the MAF.

Wish me luck.

Sorry to thread jack.

 

all this talk about fuel is awesome, dont get me wrong. but I want more on the damn supercharger!!! with all due respect

 

well once you get into the power levels this s/c is capable of, you're eventually gonna need to the fuel setup anyway. might as well learn about it now

 

so with this you will not need a return-style fuel system... correct?
so how big of injectors would you need?

 

I'm also curious as to know the fuel demands. i know its said not to be a bolt on kit, but would there be a sufficiently smaller pulley to run on the supercharger to be able to run on 42lb injectors, or would it be spun way to slow to be efficient or useful?

 

Do you mean a way LARGER pulley?

 

sorry, thats what i meant, a larger pulley to push less air for the 42 lbers.

 

my question to this is why?! if ur gonna buy this its for more power..why would u back it off?! just doesnt make sence to me if ur gonna dead it down below a m62 then i dont see the point of buying it..

 

i mean more for a temporary purpose til 60lbers are bought, installed and tuned, but i guess i see your point. Probably shouldn't install it til power is ready to be made, it is a pretty serious blower

 

Yeah... that'd be like buying at GT42R turbo and hooking it up... buy only running like 5 psi so that you can use your stock injectors. Haha... yeah, not really worth it.

 

I can't wait until that extra tax refund thing comes. My money I think is going back into the Australian economy lol.

 

I know you're just messing around! All the threads we get in lately seem to go this way. I just have to say that as a catch 22 clause up front before I join in on the fun!

As for the 750's or 875's, I'd love to see them tried out on our HPTuners controlled PCM.
Paul, do it....hey ::head nod:: do it....

If we could get those to work well it would make the 400+whp mark a lot easier to get to for sure. When do we need to upgrade the fuel pump though is what I'm wondering? Most Honda guys upgrade to Walbro 255's at around 440cc even know I've found you can run 560's on a stock pump without a worry. We're already up to 60lb injectors which are equivalent to 630cc's, so how much farther can we go safely?

 

I dunno anyone know what are max gph is on our fuel pumps? or at least what size they are.
Anyway sold some extra stuff I had laying around, so tomorrow I'll be ordering the fuel pump and what ever else I need to do the fuel system over.
BTW does anyone know if the SMG fuel rails for the older eco's will bolt up to our motors? I would much rather use a straight flow through rail then the 02 cavi rail I got.

 

Paul are you going to try the injectors before the new fuel system or are they going to be a part of your custom setup?

 

honda, in their worldly wisdom, didn't plan ahead in 92 that the b series would see a level of hp that they are being pushed to now. hence the tiny pump from the factory. it was ment for 300k miles of flawless operation. not 100k of 500 fwhp.

dropping fuel pressure on th lsj is a sign of the pump running out of breathing room. or a clogged filter. either one

oh heerrooooooo

long time no talk

i do what i can

 

Yea, been real busy and the weather sucks. How's stuff?

 

cold, snowing. again. usual stuffins. work sleep, video games. repeat

back doin better?

 

Much better. Thanks. If this weather ever clears, I will pulling out my 42s and putting the 60s back in. My fingers are crossed to get some numbers for the 60s that everyone can use without all the idle and decel issues.

 

no surge with a/c or defrost on? i have since adjusted my driving style to compensate for this cute little lsj ordeal. just seems a bit annoying sometimes. oh well

 

I was doing some research on fuel rail designs for return setups and the 02 cavi isnt a bad setup at all...It allows us to keep the pulse dampening capability of the lsj rail end with the controllability or a return line...I was gonna go straight thru but i think im going to try the cavi first.

 

What benefit is there to having pulse dampening in a return style system?
