Greddy elbow with injector holders, AIC, 2 x550cc injectors, etc PROJECT.

You should be alright with 550/1680, I reckon I shall end up with that, apparently should give you a nice idle and cruise as your keeping the small primaries, there is talk of a stumble when injectors come online (partial throttle not WOT), but can be mapped out from what I hear by adjusting transistion points and things like that.

Although saying that 850 primaries wouldnt hurt if your going for 500 fly Just dont think it will be a necessity

Only my opinion though, fuelling seems to provide fuel for a rich debate!

It does have a nice idle and cruise now and mapping was limited by injectors, all other work is done (pump, port, single, etc...) except water injection which Im going to research right now.:Typing
Do you know of any cheaper rear rail kits than the ones on offer over here?

[Warthog]

Well boys can I come in here!!!!!!!!!!! Slience was the reply so I will anyway.
I\'ll bid.................... No back in your box, Clayton.

Right, I\'m running 550 prime 1680 sec with a 044 fuel pump and fully upsized fuel lines ( this is important lads you need to get the fuel to the injectors so don\'t skimp -- normal lines are 6mm, uprate to 8mm/10mm.)
I have not noticed any blips on change over, but then Max Tuned it so he would have fixed any problem like that.
There has been mention of going for the 500bhp flywheel fig. I am running just under 400 at the rear wheels so I keep this side of the 500 at the fly. I WILL NOT go through that bench mark until I have the Motec fitted, the reason is there can be an issue with the Apexi pfc that it does not hold a perfect electronic timing line after 500+bhp flywheel, I don\'t know if it always happens or on which model, I am not prepared to take a chance and have held back. I was always going down the Motec Line due to the fantastic tuning results that the Aus lads get, so it was just about me being patient.
The motec,4" exhaust and some other goodies will be going on soon and then I will get what I\'m after and that is 500bhp at the rear wheels that I can use.
Anyway your views.:Ladys-man

Little thread to get your research going

I think 400\'s about the best you\'ll get, some American kits work out cheaper but not by the time youve shipped them over and paid customs, remember the 400 quid kits normally include a fuel pressure regulator for that price which is something you\'ll would need for additional injectors too, so add another £100 odd quid on. Unless of course you have already got one, I see youve uprated the pump (which one did you go for?)

Thanks for clearing up the stumbling issue Hog, guessing the negative reports about it are from maps that didnt address it maybe?

I never knew that about the apexi...very strange! and worrying, although not for me yet!

Shall bear in mind the fuel line comments too, that is a good point, kind of thing that could get easily over looked.

Oh and how much are Motecs going for these days, I remember configuring one on a website with all available options and got well into the 4 figures! Do look great bits of kit though.

That was the reason I didn\'t run as Rotorpop, we just ran out of time getting her fully prep\'ed to run safe. So I pulled the plug, as I said to Geff it was more important for them to get themselves sorted. He had got so many cars ready that they hadn\'t even got theres done.
 I know where I\'m going with my FD ( down the shops to get some fags and beer ) and I am prepared to wait.
 Sometimes it\'s about money and then sometimes it about money.:evillaugh
But I am now getting close to where I want to be for next season.

Ref the Motec, I was able to pick up the one Gary MARKS was selling it is only the M4pro but it has full lam/traction & launch contol enabled. I got it on here secondhand £750+ It will do everything I want it to do at the moment. If I need more then I will upgrade and move this one on. But I think it will do for now.

[ScuttleRX]

Wish I could say the same, Im close in my head as to how I want mine set-up, but in reality I havent even finished building the garage yet

Time to mull things over though is very handy, too easy to rush into things, often picking the easiest option, and ending up with a bit of a mish mash.

 Thanks for the link. Ive already got the FPR - does that mean I save 100 odd on the kit price? If so - Cool. Pump (and most of the other work) was done already (JD and Kerim built it) and Im not sure which one it is but if its not up to the job then it will show up at the mapping Im sure.

Interesting. I will look into that possible Apexi shortfall further. If it means 480 to stay safe then for now thats fine. It feels quite quick now to be honest, defo faster than I thought it would be and Im used to mental kitcars. But inj duty is hitting 96+ sometimes. It looks like 550/1680 is going to be OK if thats what your using.

[stylus350]

And thanks for the fuel line thing. Something else to check/get done before the injectors.

[ScuttleRX]

I cant see why not, was it the reworx kit you were looking at for £390+vat, that includes aeromotive FPR which is listed at £125+vat.

Without the FPR should be £311 inc vat....maybe a little more if the rail kit is a bundle price

I may still move my injectors but not at the moment, one step at a time. I am a firm believer in doing mods a step at a time. I can then see the gains in bhp/ftb, lower intake/water temps, etc. It can be a pain but if something is not right after doing it at least you know what you have just done and not well it could be A,B,C,D,E,or F.

Yes - thats the best way. You have patience. A virtue I lack. :2Rolleyes

Interesting stuff, I\'d still have prefered to go down the greddy elbow with aditional injectors route but now that doens\'t look like its happening i\'m thinking.

I bet I end up going with 4x 850\'s as I have the injectors sitting here and all I need to do is take the rats nest out again and get the primary rail machined down.

I\'d prefer to go for a setup with 6 injectors to be fair though as I\'d like to keep the 550 primarys. What I was thinking was drilling the UIM and mounting 2 top feed injectors in that and changing the primarys to top feed to then getting my mate to make me a new secondary fuel rail that I can use to the run to all 4 secondary injectors with braided hose, make sense, what do you recon?

[Warthog]

Allstaruk pm to be sent.:Thumbs-up

[stylus350]

I have no idea! But it sounds like a plan

[ScuttleRX]

Sounds interesting Al, so your 4 secondary injectors will be where original location of prim/sec\'s, and your 2 primaries will be in the UIM.

Something like this...
