Title: Fuel injection forum
Post by: ferretjuggler on March 19, 2011, 01:14:12 PM
I've been mooching around on the IFSJA forums again

They've introduced a separate forum for Fuel Injection conversions
AMC I6 and V8 mostly, using what kit is available in the USA

Bearing in mind that £2 a litre is being talked about already in the UK, I'm thinking there will be a lot more interest over here too, as wallets get squeezed even further.  :banghead:

I'm thinking something similar might be needed on Birtys :017:

may be worth considering a 'modified fuel' section, with a broader remit, such as carb to injection, diesel to veg oil, gas conversions and adding turbos etc.

non standard fuel systems do need a slightly different skill set and we have plenty on here with experience..

There seem to be a load of 360 powered CJ7s owned by Birtys

A TBI conversion looks more attractive with every fuel price rise :011:

it would be interesting to see but i doubt many of the  carb'd jeep owners on here would have the technical ability to fashion an injection system themselves I could see a lot more of them relying on taking it to someone with more mechanical knowledge to install   so it may have limited posters.

so how much difference is injection gonna make to mpg on a 360/401?

According to the good folk on the IFSJA absolutely none :017:

Well maybe 1-2 mpg better.

But then they were reporting a 20-25% increase in power and torque over a 2bbl carbed 360, with the ability to out drag hot hatchbacks at traffic lights :icon_eek:

If you're gonna drive like a psycho you really can't expect a fuel gain can ya?

you dont have to fashion anything there are several kits and methods and mostly the mechanical side is not hard the wiring may take more tinkering the big but seems that there is not much gain in it over a carb for the investmant

better results possibly can be gained from diesel conversions but that is a huge can of worms in itself

Megasquirt?

I've recently seen a turbo conversion for the 4.0, seems interesting  :icon_twisted:

I keep toying with the idea of a HHO or Browns Gas Converter, is said to improve ron figures from 98 to 120.

As for out dragging cars of the lights mines been cammed, headers, edelbrock inlet manifold, holley four barrel and MSD ignition so it'll beat just about most things. As they say ' It'll pass most things apart from petrol stations ' He He....

ive been watching a post on the landrover 4x4 forum
http://forums.lr4x4.com/index.php?showtopic=29047 (http://forums.lr4x4.com/index.php?showtopic=29047)
it seems the argument for hho is a little flawed ...as they bicker about entropy for three pages i got a bit bored. but i am glad i saw it to the conclusion which appears to be that hho besides being dangerous ( i know first hand as i use a hho generator running on (mek) methylethylketone on a daily basis which is a standard in the jewellery trade in place of propane or oxy acetylene as mek produces a higher temp as does methylated spirits, and its nearly blown my head off a few times :)
 the net result in burning high grade fuels or using injection systems to create more bhp , disregarding economy ( supplementing fuel ) is that result of the hotter burn even with fancy timing curves the chambers (cylinders) and pistons rings etc all decay faster due to greater thermal stress and inefficient lubrication, resulting in premature engine failure
so unless your dragging your 4x4 down a strip for thirty seconds a time on nos
stick to lpg as the optimum fuel conversion     :steeringwheel:
