I was just thinking that the radiator would only take up 2/3rds of the fuel tank hole, and the other 1/3 would be used for sucking fresh air into the boot. I could even make up some tubing to direct the air through the radiator somehow. But that might not be needed becaue the boot is sealed.
Fans (positioned underneath the radiator) would suck air through the radiator, drawing the 'fresh' air from the boot and releasing the hot air underneath the car.
The radiator is only really needed when we want to run the car on premium unleaded. This will mostly be during cruising at car events or for testing. When run on methanol (at the drags etc), the engine won't really get very hot.

you would get good airflow and keep most of the heat out of the boot

LX406 - The boot will be full of fresh cool air, which is drawn in directly into the boot through a port hole. This cool air is then drawn through the radiator (by fans)to the outside of the car. There would be a constant flow of cool ambient air into the boot. I don't expect the it to get hot at all in there.
We'll be running fairly low on space in the engine bay, but there may still be space for a small tank. We haven't ruled it out as an option.
IPRALC - yes we have thought about a dry sump, but didn't think it was necessary.

The only thing I'm a little concerned about is that the air might be continually recirculated around and around. It would be ok when the car is moving, but when stationary the hot air may just hand around under the rear of the car. It might not be that bad. What do you think?

On a side note...
We bought a hi-stall convertor for the powerglide. Although we don't actually have a powerglide yet, but we'll get one eventually. We bought this convertor off ebay. Its a Dominator 5500rpm convertor!! Awesome!!!
The guy I bought it off said the stall speed has been designed for a small block chev, so I expect the flash stall to only be around 4500rpm with a little ol' 4.0L engine... but the boost will help with torque to push up that stall speed a bit. This convertor will be helpful off the line when we get new cams.
Next on the shopping list is a big throttle body.

I doubt that this will restrict power. Check it out, its massive!
And here it is next to an XF throttle body. The XF one is what VL turbo guys usually use as an �upgrade�.

I've now got a 9 inch housing and axles for the LJ. Its torana stud pattern and standard LC/LJ length. I might consider shortening it a couple of inches later on. I will probably also convert it to HQ stud pattern eventually.
I'll be keeping an eye out for cheap diff centres now!

lhoon i recon if your going to shorten the 9" and change stud patternaswell as look for a centre you'd be better off buying another 9" pay for it to be cut down ect then sell the one you haveI'm slowly collecting bits for this car, but its an expensive exercise!

MRNOS - this project is coming along fairly quickly, but we have been working on it for a few months. It seems quicker because I've posted all these photos up so quickly!
Muro - Yep I've been thinking the same thing myself. I may or may not use this diff. We'll see. I could also use it for my LC, and get rid of the borg warner.

Finished welding on the top tank of the intercooler, and drilled a 4 inch hole for the air outlet to match the huge throttle body we've got.
You'll also notice that we chopped the top off the old intake manifold plenum. We're re-designing it so that it fits under the bonnet of the LJ.

Thanks for sharing the pics, very impressive engineering effort...
I think a goal for me next year is to do some welding courses, and learn how to use a TIG...
cheers,
Sam

We've now fabricated a new plenum chamber!! Unfortunately the old trumpets/bellmouths are a bit tall, so we're going to have to remake them. But the exterior is made, and you can now see how the throttle body will fit, and plumb straight into the intercooler. It all fits under the bonnet, and it should look pretty sweet!!
