The Brumbyrunner Project

Well the engine is bolted in place! The engine bay was prepped and then painted with a black primer/sealer yesterday morning and the motor dropped in after lunch.
Was hopeing to leave the radiator support panel in but there was no easy way to make it fit around the oil cooler line and exhaust crossover pipe so it had to go. I've also decided on using a 2" body lift now, so there is plenty of room for the coolant hoses. We'll have to build a new lower rad support panel about 2" further forward. The good news is that the gearstick locates in the centre of the gearstick hole in the tunnel. More good news is that I was able to massage the drivers side strut tower enough to fit the WRX booster and brake master cyl.
Brett has taken some pics so I'll see if he can post them up.

Well today we managed to finish the underbonnet wiring. There are 4 big wiring bungs I had to cut new holes for in the firewall. The rollcage runs through the original holes behind the strut towers so we couldn't use them. Dave built the new gearbox crossmember and I fitted the back half of the lift kit.
Pics soon I hope.

awesome work there on the body modifications

they should have come like that from factory!

What with the EJ20T in it, that would be awesome! And more travel in the suspension... Looks better ever picture you post. Nice work!

Mmmm, I reckon if those mods could be blue plated, there'd be a lineup of Brumby's waiting to get into the BYB workshops.

Looks very nice - please keep the pics and info coming.

Dave put the rear diff in this morning and then built mounts for and installed the tail shaft. I spent all day adapting the pedals to fit. Ended up using an MY brake peddle box with the Liberty accelerator and brake peddle. Then Dave put the steering column in. It's all coming together slowly. Much thanks to subie-wan-kenobi. Tomorrow should see the arrival of the air filter and coolant hoses.

Brett and Dave started on the coolant lines today. They are turning out really well, better than I had expected. Check out the fresh pics Brett just put up.

I presume the additional volume in the extra long coolant circuit would be a good thing for hard, high temperature runs. Just how huge are the radiator and thermo fans going to be? I'm interested to know if the OEM water pump is up to the task, or do you have plans for a better pump?

I am using the stock turbo rad and fans that came with the front cut and the stock water pump. We wont know how well the cooling system works until the car is driven but there are plenty of ways to improve it. I have an electric water pump in case, we can duct the air into the rad or possibly use a bigger rad.

The long coolant lines are a bit of an unknown quantity. If you talk to racecar builders, they will tell you to keep the rad in the stock location at all costs. It elliminates the headaches because they know its going to work. It just wasn't an option for me.

I wonder if you'll get any hydrodynamic surging throught the long pipes under hard accelleration and/or braking?

From the pics it seems there is a fair amount of pipe along the longitudinal axis. Probably wouldn't be a problem at legal road speeds, but if you're racing and going from say 200km/hr to 40km/hr to negotiate a hairpin, then hydrodynamic surging may occur through the pipes.

May also need a good pressure pump to keep the water moving through at a reasonable volume unless the pipes are oversized.

After a whirl wind tour, Brumbyrunner has left the building. He is on his way back to the gulf with the brumby in tow. It is still not complete but is running and driveable. He still has to fit the new suspension, trim the guards to take the 30's and get it cams approved.

The water issue is not a problem with the EWP we have now fitted. Cooling capacity is around 9 - 10 litres.

BTW, some more pics have been uploaded.

The tray work looks awesome. Love the exhaust piping.

vincentvega · Post by **vincentvega** » Sun Feb 04, 2007 11:04 am

the tray is starting to look like something out of mad max!

kickass work

It looks nothing like how it goes, with the 30s on there it will certainly haul hard

hay brumby runner where are you located? if your not too far away you should come race here when we have a meet, id love to see that wepond in action.
