Outer Limits 4x4 Board

Mate has an '85 Bundy and despite some mods to the engine (re-ground cam and flowed the zorst port) he is still dissapointed with the performance.......lack of power and fuel economy of around 17L/100km.

Anyone have any comments on this, is that normal for a Bundy?

Thanks.

What motor does he have? Petrol or TD

Thats pretty nasty on fuel, I have the petrol 2.4 (22R) and get 8-9L/100km in the city.

Yeah it's the 2.4L petrol.......so yeah fuel econo is almost double what you are getting Apocolypse.

17L/100km is like what the V8 100 Series gets! Check air/fuel filters, check driving styles (don't take off from the lights as quick) Does it blow smoke? What colour?

No it doesn't blow any smoke, he just had a head gasket replaced as coolant was leaking into the cylinders and oil into the radiator. That is all fixed now. He's had a new CAV type fuel filter and runs a K & N air filter.

i also have 22r - your fuekl economy sounds exactly like mine. If apocolypse is getting that economy can he come here and tune mine

i hear they are all like this. hence my post on 22r - 22re swap. hoping that will fix my problems.

also dont forget - bigger air in and bigger exhaust will decrease fuel economy (i also have this) but still it is pretty farkded at $1.30 and going up all the time.

as i have just sold my bundy because of its lack of performance, there isn't a whole you can do to the 22R to spice it up without spending a decent amount of dollars if you look overseas (USA) they have a mountain of spares and hop up parts for the 22R (including turbo conversions) but at the end of the day its still a 22R your mate is better of doing engine or efi conversion (Commo V6 or 3RZFE) to getter any real benefit

I finally got to drive mine home today (v6 conversion) It flies. Dont know about economy yet and proabably wont even bother with it as it doesnt worry me due to the performance gain from the conversion anyway!

I reckon I'd get close to 10L/100Kms in the city,
but on the highway, I would put it to maybe 15L/100kms
cause you have to milk it to get anywhere this year.
That said, I got extractors, good ones and a decent 2.5" zorst
and it goes heaps better. Also, get the carby rebuilt. After
I did this (the carby had done like 300K Kms+) there was a
noticeable improvement.

Cheers,
Bart

I carnt see any problem with the fuel economy. Did a trip to Milbradale (26km south of Singleton) from campbelltown towing a trailer of around 700kg with my Raider. The 2.6lt 4cyl petrol got me around the 24L/100km mark. Driving to Melbourne from Campbelltown (840Km) cost me around the $135 mark in fuel each way. After the raider, I'm looking forward to the fuel bills for the 6.5Lt diesel.

All I can say is I'm glad I don't have a raider, I'm happy with my fuel econo from a 4.2L diesel motor
