I got through the hill climb and had some fun. The morning was warm and dry but it pissed down in the afternoon. There were a couple of big spills, including a minor one for a gt4. The car was flawless and glad to discover it has in fact an LSD! Im thinking its probably making 150 – 160 wkw, the tyres are a little narrow on the rear so I got the tail out a couple of times in the dry and more so in the wet but think I controlled it well with the throttle. Many people were familiar with this car at the event so it was good to hear stories about its exploits. I made some nice wheelies at the start line to keep the fans happy! Few photos below taken today.
 
Steve I’ll need to speak to you about suspension tweaks....
 

 

 

 

 

 

no more progress to report, I want to focus on improving the suspension. the car sits quite high so considering lowering an inch or so but Im reluctant to change the geometry or reduce suspension travel too much.
 
the local GT garage had a dyno day on sunday, made just over 160wkw and happy enough with that given the engine is pretty much stock. I reckon a dump pipe should free up flow and make more top end, makes a hell of a noise at full song as the exhaust is just a couple of hot dogs!
 

 

good stuff mate, what turbo are u running? 160 rwkw at 12psi?? preety good

yeah its not bad, the turbo is a steel wheel CT26

That is an impressive figure for 12psi, are there any other notable mods to the engine?
 
How about some engine bay pics

It certainly gets it all out by 5k. With those revs, you could run the Winton or Wakefield 300km flat out with that!
Im happy to co drive if your keen to enter.
How many km to the tank when you push the car?
 

all is I know is what I can see as I bought the car only recently, there is a straight through exhaust with a hot dog on each pipe so I dont think its very restrictive. the previous owner was not very mechanically minded, the motor was rebuilt about 10,000 ago and he said there was some head work but he didnt know what exactly.
 
Steve I cant see me bringing the car over on the boat any time soon, you are welcome to a drive any time!

a friend of mine emailed this photo from the Hobart domain hill climb, bit of sideways action up the hill following a 90 degree turn in. when it started raining I held this slide right up the hill for 100 metres or so. these cars can be a lot of fun with moderate power
 

Done a few track days over the past few months and have had a lot of fun with the car. Ive been picking away at the excess crap to reduce a bit of weight, its quite addictive! So far I have removed about 90kg (25kg front, 40kg middle and 25kg rear), major items being the cat, power steering pump/accessories, abs and accessories, fitted bucket seats and removed interior trim, sound deadening etc.
 
I have changed the suspension considerably and brakes too and the car feels very neutral on the track. Changes are:
 - New front and rear ball joints
 - New front and rear Eibach lowering springs
 - Larger front swaybar and reinforcement plates
 - Pillow ball tension rods and mounts
 - 4 point front underbrace
 - Prothane bushing kit for front, rear and swaybars
 - Suspension geometry adjustment kit, RCAs etc
 - Late model brake booster and larger master cylinder
 - Gen 3 brake disc, calipers, slotted discs
 
I only have 2 deg camber up front so I’ll need to do something about that.
 
The plan next is for a W2A intercooler system similar to that in my other car. As Im going to remove the heating system, Im going to reuse and modify the heater lines to transfer water to and from the heat exchanger, these are around 16mm to 20mm in diameter, not ideal but probably enough. Makes a lot of sense though and will save a fair bit of hassle. I don’t think there is room for anything larger above the fuel tank and will be nice and discreet in that location. I’ll probably put a small 2litre tank in the frunk.
 
The heater lines will be modified to pass through the tunnel via bulkhead fittings, as Im planning to fasten the intercooler to the firewall behind the passenger seat and roll cage, with the air pipes passing through the firewall to the inlet manifold. This will keep the intercooler away from the heat and also free up space for a nice big air filter and box in the engine bay.
 
Im considering a small box in the system containing 1” copper with decent surface area so I can try some dry ice to reduce inlet temps even further. Will be easy to determine the before and after effectiveness of this as Im not sure if the water would be in contact with the ice for long enough to have a benefit. Its worth a go.
Im still toying with the idea of E85 and sticking with the steel wheeled ct26. I figured with all this I should have around 200 rwkw to play with. After that I’ll keep going hard until I have pushed the limits of the suspension, especially tyres before considering wider wheels, more power etc
 
 

Sounds good Patrick, post pics up as you go.
 
I have also removed the power steering, did you keep the PS rack and just block or join the lines on the rack? What does it feel like to drive/race with?
 
My plans are also to put the WTA IC in the same spot, funny i was talking about this the other day, seems the thing to do, but i am still yet to see pics of anyone setups, so let us know how it works out if you do it. 
I cant fit it in between the cage and the firewall, (not that i would want to due to heat) i assume yours would be the same, so it would be in front of the cage, would like to see how a passenger seat will fit.
