N/A Supercharger Project x2

taza said:
Ive heard of them in action, they are crap. Do nothing to power, if anything restrict air flow.

Does't your 2.5 have enough grubnt for the job? Its more your low range, right that lets you down along with the open diffs?

Thats why im doing the supercharger. I have decent gearing (4.11 diffs with 45% lo range) but not the power to back it up. I need more low end torque and just general power thus the SCshould give me similar power to your 2.5 but with more torque, mainly in the low end too :cool:

The 2.5 def. has grunt & good power, but once you drive at levels above 9,000ft (2743m), like going up the switchbacks in Colorado, you will see what i mean. It's not the incline that kicks a 4 bangers butt, it's that there's not near enough air so you lose a ton of power. That's where the turbos/sprchr or bigger engines come in handy. At 10,000ft, i lose almost 50hp because of the thinner air. Equation for HP loss at elevations.
hp loss = elevation x 0.03 x hp @ sea level)/1000

Those superchargers sounded almost too good to be true. Never heard of a thing that they try to butter-up so well and it perform the same.
 
we don't have to worry about high altitudes in West Australia

At the Pikes Peak Hill Climb they have the unique challenge in racing of getting max power at the base & also at the top, I think 3000ft difference. Usually the top guys wait till sunset so its coldest for their run: the colder the air the denser it is, combats the thin air at altitude.

I'm more concerned out the bloody heat here. We have another 2 weeks of over 40c.

I've noticed that you guys were having a hot spell at the moment :cool:
Just make sure you don't overexert yourself too much in the heat & keep up the fluids. Dehydration is the last thing you want happening to you.

Hadn't thought about Pikes Peak, the climb from the base (9390ft) is right at 4,700ft, but at that altitude, the Forry would be at less than 96hp! total loss of 69hp. Crazy! We took a pontiac G6 up it the last time and it did alright. You just can't have the A/C running at that elevation, otherwise you'll burn it up.
 
Haha yeah Taza, it would make it up fine...in high range lol. But you would need to look over the edge, in some places its a 1000m almost vertical drop!

Slow up, fast down :huh::rotfl:

Haven't had a chance to read through this whole thread, but how does a system like this sound?

Actually sounds pretty safe & would def. come in handy at the higher altitudes. I know some places in the mountains when we got up around 10,000ft, the forry was suckin hind handbag!

Total snake oil. As taza said, they're more likely to restrict airflow than aid it. I say this fully-admitting that I've never one run personally - but having spoken to people who have, this is pretty much what they experienced with them. But, related to that:

Having driven on exactly those roads this past Summer, I'm in complete agreement. My EJ25 started feeling the effects around 7,500 feet; by 9,000 it was noticeably down on power.

It's not the incline that kicks a 4 bangers butt, it's that there's not near enough air so you lose a ton of power. That's where the turbos/sprchr or bigger engines come in handy.

Yes and no on the blowers. They'll help at altitude - but remember that, similarly to a naturally-aspirated engine, their efficiency also drops off with the air thinning out. I'm not saying that they don't work at altitude, just that the effects aren't as helpful. The tendency is for them to reach an efficiency plateau followed by a drop on the gains; the law of diminishing returns definitely applies.

Those superchargers sounded almost too good to be true. Never heard of a thing that they try to butter-up so well and it perform the same.

'There's one born every minute' very much applies to them :icon_wink:
 
Little update guys!

The battery relocation.

I should be mounting it tomorrow and hooking everything up if all goes to plan! Can't wait.

Looking good taza :discomonkey:
Thanks for the update & pics :raz:
Can't wait to see how it looks once you've got it mounted & hooked up :)

Sorry I missed your message Taz! New house, no internet, so don't get on ORS as often now.
Looking good!
 
Ahhhhh? you mounting that to the engine or the engine bay/inner guard where the batery was? if to the engine no prob but if you're mounting it to the inner guard the engine jumps all over the place on it's mounts so you may have trouble keeping belts tight let alone in place on the pulleys.
