Well I just got a hold of some Golden Eagle Fuel Rails and let me say they are beautiful. they come with -10 feed and return. the only things is the injector bungs are not that big. they are the same size as my str fuel rail which means they will hold my holley 1000cc injectors but i know the 1600cc bosch style will not fit. does anyone know what 1600cc's will fit this rail?? delphi??rc???if not what rail will they fit that is premade. we made the rail for our race car but I dont want to fabricate to save time. i just want to bolt it on and go. thanks for your help.Mike

Just take your rail to a machine shop and have it bored out to fit the bigger injectors. It shouldn't cost much and to my knowledge there's not a rail other than custom that will fit those injectors. We drill all of ours out.

thats what i figured.We can drill it out ourselves I guess. thanks tony!!!

GRT

told you so!!!! just drill them or for about 100 bucks GR can make you 1 or 2

thats what i had to get done on the aems on mine for the 1600s as well.drill them mang-pdang

this is a shot of it after tony did a little work to it and got it anodized....

If you cant find anyone to do it for you....we have the bosche tooling here to drill it out and flare the opening so it doesnt rip the seals.....Ill do it for nuttin for ya...I just wanna see that new fuel rail....

RS Machine charged us $20 to do our rail. Because it needs a hair over 1/2" opening, figured it was easier to do that then to buy a bit and do it ourselves.

thanks for all your help GRT. GRT is my pain in the *** partner by the way he built and drives the h22 race car. I cant wait to line up with him and whoop his *** in the street car. LOL

i cant wait to see that race!!!!

GRT

your a few hp short my son I dont think your ready for the big guns , remember who builds your motors hehe!

who dose anyone need 1600cc injectors? That seems a a bit overkill, maybe I am just stupid and don't know. Even 1000cc's seems nuts to me. Well, unless its an all out race car. Flame if you must, I'm just tryin to learn.

MotorMatrix.com

when trying to make 650+ hp with the proper mgmt nothing is overkill. We believe in not trying to max out the injectors before going bigger. we go big the first time out. hope this clarifies it a little for you.

1600cc's good size for Alky.....or just crazy people trying to support very large turbo on fuel and figured what the hell 1000cc / 1600cc same price who cares go bigger just in case if the switch is made to Alky.....I dunno....I was maxed out on 8 750cc injectors last year...but that was batch fired injection....who knows..

lol

we maxed out 4 800's and 4 1600's together last year! 8 1600's for us this year!

MotorMatrix.com

we started off with 8 1600cc's on our alky car but i dont think we were close to maxing them out at 700hp. bigger is better on injectors if you have control of them right??

AR Fab

thats on alky too right?.....

As long as you have control of the bigger injector then you're ok. Some cheaper engine management systems can't control a big injecor very good at idle. Haltech for example, you can't run much over an 800cc injector without having idle problems. The problem is in the injector drivers themselves. They all open an injector the same way, but they close the injector differently. Haltech has a very slow response time on the closing of the injector. When it closes it should go from 12v straight to ground. The haltech and many others don't cut the voltage down quick enough and at idle the injector doesn't actually close all the way because of very low voltages still present. It doesn't matter as much at higher rpm, but it dose still matter. The Motec opens and closes the injectors with the same speed. It actually immediately brings the voltage back down to 0 so you have an accurate signal going to the injector. This is why you can idle 1600cc injectors on gas with no problem with motec.

Oh, and we did max those injectors on methanol. I don't think anyone could max them on gas!

Holley makes 2 fuel rails. One fits denso type inject. and the other has the larger openings for bosch style injectors.

highbrid

maybe i missed it, but what management are you using to tune the 1600cc injectors, motormatrix. Im just curious if youre using hondata still like it says in your sig. Have any of you tried those big injectors with the aem ems?

shortyz

im guessing motec....

MotorMatrix.com

I'll be running speedpro on the new setup. it can control 1600's no problem. frank from sfp runs 4 16's on their 708 whp street si and it idles perfect and gets 20mpg,out of boost that is. I'm not a big fan of the ems. Id stay hondata before runnign ems.

b18bturbo

yeah the speed pro did also for me. i just dont like it how its hardeer to run 8 setup on it than 4.... motec or autronic is the way to go now..

Adi Radoncic

Tony1 how big of injectors do you think the Aem Ems would be able to handle and idle with. I have 1000 right now but I haven't ran the car with them yet, I'm thinking about going with 1200 to 1600 here this year..
Thanks,

Adi

speedpro still works well and will continue to work well. look at the old technology in the haltek.lance still finds a way to run 8's.

Viren, what brand are the 1600's you sold me? Are they new? HOw come some of teh paint is chipped off? Just wondering...

and I am probably gonna run teh speedpro or Autronic.
