Outer Limits 4x4 Board

Anyone got some pics/tip for upside down chassis welding using a gas MIG?

Ok, maybe one of the resident techs can answer this. so here goes.

Looking for an Auto trans to go behind a LS engine, My preferred choice is a 4L80E, But that would require some sort of computer to control it, the only decent aftermarket setup is to dear at near $1600 US.
Trying to find somebody ...

Whens it on till bud? Ill try and make it down for a squizz tomza

That thing is sooo nice and wholey! Ours looks like a jungle gym with a diff and only two tyres stuck to it

JrZook, what type of car are you guys building?

Hi ours it a bit of a bitsa are we are rebuilding it after a dis agreement with a tree. Its a GQ front end with an MQ/MK rear end running a 318 valiant, all tin/corriguated iron custom body. We have finally found another GQ front and hopefully will ...

Post Help needed for scout troop, Brisbane.

Thanks guys!\

Think I have tracked one down hopefully, will see how it goes. I too thought that there would be a few around anyway and as well after the floods but not as easy to find as I would have imagined!

Thanks for the offer mark, will keep it in mind! Do you have many patrol parts around ...

What leafs are they? Stock? Looks like they have wayyy to much arch and are also super short!

Hi

Don't know too much bout these big beasts but are the front ends of the chassis from the radius arm mount forward the same in terms of shock, arm, spring, panard and steering component mounting points?

The reason I ask is that Im part of a scouting group here in Brisbane and we have suffered ...

just got a quote from lindsaytyre.com.au of $275ea for the maxxis 764... add freight and im guessing its going to be around the same price as the KM2. Still waiting on fourbys to price it for me, but its looking more and more like i'll bite the bullet and go the KM2 .

edit: fourbys called back ...

Might be able to help. PM sent

Wheres the fuel bowl located on this carb? Directly underneath the throat? If so it should work quiet evenly on any angle. If its an offset bowl id set it up so the fuel level is affected on side slopes rather than up/down hills. Im pretty sure your sideslope angles you drive would be most of the ...

44 to 49 rwkW, 10% sounded better, it's all relevant. 5kW in a 45 kW vehicle feels a lot more than 5kW in a 200kW vehicle.
The vehicle already had and exhaust and extractors, standard intake.

Cheers

Should be quite noticeable in the lil jim! Equivalent to 200kw to 220kw for comparison in net ...

So 10% gain to peak power as well? 43kw to 47.3kw?

Use the 1L half yokes t/case side and mate them to your 1.3L uni's and shafts.

Dan

drop shackles are good when used with the right bump stops. so as when one wheel is pushed up into the guard it levers against the bump stop forcing the other wheel into the ground, if your not hitting your bump stop as either it isnt there or your to high in the spring lift, then yes the drop ...

Is there any real reason why other fluids (not water or cordial!) wouldn't work? ATF is a hydraulic oil isn't it? Any fluid with a high boiling point should work shouldn't it?

This question is asked out of curiosity, I would never run anything but brake fluid.

Yes. Although water doesn't have a ...

I wouldn't exactly agree with this, the fuel transients do not work with an E38 ecu with the MAF removed that can lead to fuelling issues related to accelerator pump activation. The large MAF's in these are generally best left in. Only the LS1 ecu was used by HSV without a MAF.

Joel

So this E38 ...

i'm a little rough on th details, hopefully someone wil fill in the details soon.

MAF generally also has air temp sensor built into it as well. it gives a much more accurate measure of the amount of air going into the motor.
MAP is a bit crude in comparison. they only measure pressure. also i ...

Hey Struth at the end of the day the results improved and thats what matters but it's interesting a 4" snorkel increased power over the 3" even though the throttle body further down the path is only about 2.75".
Have any other work done when you had it dyno'd?
So I'm wondering how a 3" intake was ...

A static power figure will always be higher than an accelerated one at any particular speed and rpm as the driving force is no longer being consumed in accelerating the mass, the losses are now friction and windage only.
Joel

What I was trying to say was that if the ramp rate on the brake is ...

ramp rates also have an effect on the output, also strapin the car down. i dont fully understand the setup for our dyno as our boss is to tight to get us trained. howeva wen it was installed we were told ramp rates, and to make sure the car is strapd down to keep pressure on the front roller ...

Have a look at some of the VW sites. Most use the webers. Good for about 7psi blow-thru setup. Weber 32/36 with a pressure referenced fuel bowl and high pressure fuel pump with rising rate fuel reg will work. Just remember to knock your timing wayy back.

Anyone know how much wider these are to the std WT flare?

Yea shouldn't be a problem, as it is an AFM anything you do around it that changes the airflow will be accounted for and compensated. Also just a note, they do have finite range but keeping it N/A will be no problem.

Dan

As the cryptic title says I have a sierra ute with 1.6 EFI, and 4.11 diffs (dead) and I am upgrading to WT's. I have been offered some 4.6 diffs, but I'm not sure if these will be too low or not.

I drive the ute 6 days a week in city and on h'way.

Will it be revving its tits off?

Opinions ...

This is my first play with a turbo project so here are my calculations to check to usability of that turbo, from the map, on the 250.

map -> http://www.ihi-turbo.com/turbo_RHE-RHF.htm

Using 7 psi as the max boost I find the boost ratio (or compressor pressure ratio) to be:

BR = (14.7+7)/14.7
BR ...

Thanks for that tech tweak'e. Might see if i can add a water resivour and try to set up a thermal siphoning system to aid in shut down temps.

Still have a heap to do to even get started on the projects but the basics are
Yamaha 250cc V-twin
redline 8500RPMs
std comp 10:1, will bring down to 8:7.1 ...

just leave the water connections not connected. as allready mentioned its only for shutdown. lots of 4x4 turbo conversion simply leave it off.

if you really want to use it then connect it straight to a cooler. however don't forget you have to mount the turbo at the correct angle and route the ...
