xr6 fuel regulator

Gday All,

have a 98 xh ute with crow stg 2, pacemakers, 10mm leads 2.5" system etc etc, would it make any difference power wise putting on a xr6 fuel regulator. How much more thirsty would it make the car??

cheers

Re: xr6 fuel regulator

Yes you'll probably find the car will go slower and use a lot more fuel, can't say for sure thou. but i would think that considering normally they run rich that it would over richen it.

Re: xr6 fuel regulator

Yeah we found this out at the recent SA E-series dyno day. Most of the I6's were running quite rich even with the stock fuel regulator. Most of them gave another 5-10rwkw when the mechanics lowered the fuel pressure a little. Only one real way to see though, get it up on the dyno and check AF ratios. Aim for somewhere around 12-12.5, as this seemed to give the best results.

Re: xr6 fuel regulator

i notice a heap of guys all going for the xr reg, on their very mild hot ups, even a car making 140rwkw, will not need anymore pressure than std, i dont know why the use them, it must just be in their heads that using an xr item will give em' more power. my std eb, when making 118rwkw was running in the 11's a/f ratio, why the hell you would want more fuel in there i dont know...

Re: xr6 fuel regulator

it will flood in the morning, belt out shitloads of black smoke whenever u give it stick. as for fuel economy i reckon u'd even get a slight whirlpool happening in the bottom of the fuel tank.

thats what mine did anyway.

Re: xr6 fuel regulator

I put the higher pressure XR6 in my AU, and noticed straight away more mid range. Haven't noticed smoke or any diff in fuel economy. The car is happy to really rev. I have been told by Mock's and others that the standard reg is fine, and I'm even contemplating an adjustable reg so I can back it off more on a dyno. Am going back to the standard reg this weekend so I'll report on the effect, but the computer adapts over time, so it won't be a good indication. Save the bucks man, they cost about $90 if I remember correctly. You should be able to get a basic adjustable for this! The things you learn!

Re: xr6 fuel regulator

i thought it would make it too rich, best i try gettin more air in.....getting a vernier cam gear soon and a 3.73 lsd so that should help things along a bit. anyone achieved any success getting more low down acceleration without affecting mid to top end much????

Re: xr6 fuel regulator

Been running the standard 2.7 bar for two days now, didn't pick much difference so far to be honest!! I "feel" it has lost low-mid a bit, but still rev's the same. In the end it does stuff all on a standard engine IMO.

Dinga, get the biggest scoop you can, upgrade to the newest inlet to suit, smooth it out internally, minimise the rubber accordian style elbows, and just try to make it as straight and smooth as possible. Get a K&N or dragon filter, or upgrade to an in box pod. Heat shield as much as possible. Will all be small diffs, but they add up.

ROFLMAO!!!!!!!!! thats freaking hilarious!!!!

by the way: as an experiment i put my XR reg on 6pacs car the other day (stock head but DEV 5 cam, zorst etc) and it ran like sh!t! we didnt even bother to take it out of the driveway because we could hardly get the thing to idle in park, let alone drive!

main reason is the stock comp attempting to come to terms with a monster cam though, so its not a godd indication.

Re: xr6 fuel regulator

When this was done did anyone clear the eec ??? From the old settings??? Higher f/p will help higher in rev range where 19 inj maybe pegging out??? Porting, 3 angle valve job etc to allow more air in should help also...
