Rally's MY04 Forrie- Poverty Pack special

Purchased second hand. Rear diff and instrument cluster replaced under warranty. First change was to fit CB UHF GME radio. Car has externally mounted windscreen aerial bracket. Just purchased set of new KYB shock absorbers- the originals have had it- will install when they arrive. Next step is to replace standard steel rims with MY99 WRX rims. Then sump guard and driving lights.

Looks good, Rally :biggrin:.

Flaming surprised that you got your Forester up that, let alone with the trailer on behind. Well done :lildevil:.

Good driving and technique would have played some small part!
 
When I entered the water I still was not cot committed to my exit line. When I was about half way across, I decided which line I would take. All the cars before took a different line to me, and most were more experienced than me. But I had confidence in my decision making process about such things, so I chose a different line to them. I don't know what line those behind me took- I did not hand around to see. It is my belief I chose a better line, but that is what driving is always about- be it off road, on road or on the race track. I also have no doubt that the diffs played a major part in all of this as well. Everyone in the club was great, I really appreciated the help I received from a number of people in the club. Had it not been for them I would neither have got that far nor got out. I am still toying with the idea of either supercharging or fitting an H6.
 
I don't rule it out, but I want to see how the 1.447:1 low range works out. I also want to have good long range touring- everything is a compromise in the end isn't it
 
that last pic shows the climb out nicely. nothing like some water to make it slippery lol :iconwink:

I reckon you'll find the 1.447:1 will be enough with the EJ25 & your diffs. Or while you're opening the box why not put in the 1.59:1 LR? :poke:

The 1st pic cropped a little could be your new avatar :lildevil:
 
Too much like hard work! Besides, the I have the gearbox with the 1.447 low range sitting there ready
 
I think the change to 4.44 will impact your range a lot less than a blower or h6 will :)
 
I think you might be right. But I am not a fan of high revving engines for long cruises. The trailer has room for 3 jerry cans straight up, with room for more if needed.
 
Realistically, the change is less than 10%. 4.10 stock to 4.44. So if you currently do 2500rpm say at 100kmph it would be like 27XX with the Ratio change.

It might even improve economey...

Not quite that simple ... :iconwink:

4.44/4.11 = 1.0803 increase in revs.

However, the increase in stress in any system is equal to the square of the increase in the stressor, in this case, the square of the increase in rpm.

Therefore the increase in stress is 4.44/4.11 = 1.0803, 1.0803^2 = 1.1670, or 16.7%.

Rally has an SG, so standard gearing in the FD is around 38 kmh/1000 rpm in fifth as things stand. Reducing the FD to 4.44 would decrease this to around 35 kmh/1000 rpm in 5th HR, i.e. around 2860 rpm instead of his current 2630 rpm.
This would decrease his fuel economy by a fair proportion of the amount that he would currently get driving on the highway at 100 km/h in 4th HR with his current FD gearing. Not as much, but it would be somewhere in there.

Even putting the 1.447:1 LR gears in, instead of leaving his 1.196:1 gear set there, will impact his ability to use LR for towing when not off-road. After looking at that bank he managed to drag his trailer up through, I don't think he needs to swap his LR gear set over either!

As Rally has already said, all these things involve compromises of some sort.
 
Agrre all except about the low range. The car stopped trying to get up the hill because I had to slow going over a mound. The car was struggling and I called it off when it got down to under 1000RPM. The Landcruiser turbo V8 diesel had to tow me up the rest of that hill and a few more besides. I certainly would have had more of a chance with the 1.447:1 low range.
 
^ And that's what we both mean about compromises, mate.

I'm prepared to live with the standard LR gear set, because there is no way I am ever even going to try to tow my trailer through that sort of stuff in your piccies!
Probably too much of a coward these days to even try it with just my car and no trailer. The other thing is that I will rarely, if ever, have another vehicle with me, and that changes everything.

I can see the benefits you will get from the 1.447:1 LR gear set. Just remember what Venom has said about the need for a secondary oil feed to them when you put them in. His own practical experience with them, and that of others he refers to, indicates that this is an essential modification.

It actually works the other way around. With a higher diff ratio, LESS stress is felt by the drivetrain. Landloosers & Spewtrols who put on big 35" muddies often experience gearbox failure as the stress felt by the gearsets becomes too high. 5th gear destruction apparently is very common in this situation, esp if towing a lot.

Even putting the 1.447:1 LR gears in, instead of leaving his 1.196:1 gear set there, will impact his ability to use LR for towing when not off-road. After looking at that bank he managed to drag his trailer up through, I don't think he needs to swap his LR gear set over either!

He would still be able to use his LR just as much offroad, it simply becomes more effective. As such he wouldnt need as much momentum so the stress on all components would be less. & onroad there arent too many times you need LR, starting on a very steep hill with a very heavy load would be one such situation.

Remember in a Subie the LR is a weak point & needs to be protected as much as possible :iconwink:
 
Remember reading a big post by Stilson that 1.447 Low range and 4.44 ratio final drive is probably the best and most likely to last for the subie gearboxes.

In my mind the 4.44 FD is going to put less load on the gearbox as it will be easier to turn.
 
I can only go off the photos others give me, as I did not take any
 
New low range goes in tomorrow, as does new throw out bearing for the clutch
