any update stao on that rb25det gettin tuned? the one only running 9psi for now

He drove off to Adelaide, probably come back in 2 weeks to finish off the tune. I will postup result once its done.

Ok. This is our latest dyno result based on a ATR28G4 in a .64 T28 rear housing running on a build CA18det running 98 fuel. Car made 316rwkws at 24psi at this stage ( Note: see how the power curve is still rising. ). going to do a final tune in few days. This turbo would be making some mad power on RB engines using .63 rear housing.

ATR28G4 would be some thing similar to a GT3076.

Its my daily car. I drive drive it around to deliver turbos. lol

CA's modifications: Forgied pistons, Split fire coils, Nistune ECU, FMIC, 700CC injectors, Z32 AFM, 256dur/8.9mm cams, Tomei adjustable cam gears, ebay manifold and 3inch exhaust. Every thing else not mentioned are stock.

That looks good. OP6 is still small. You need .63 rear. I can get one machined for for $250. But you need to make a new front pipe. Check That exahust place next to Trents.

The guy got EPAed and defected on the way back from SA. its going to be a while before it go back to the dyno. Hoo and by the way there are plenty of ATR43's progress. The laser cutters finally got our flanges ready. So just matter of putting them together now. should have 2x samples done by weekend.

Its similar sort of CHRA. Rear housing is different. It will be a.63 Rear housing. that we made our selves. I'm plaining to make 4 different types of CHRA with 2x different sized A/R housings. which are powered from any thing at 230rwkws to 330rwkws depends on driving ability. I will post some photos once I get the housings finished.

no one does, i drive to Hoppers. Car runs 100% time on E85. Jerry cans ftw! :(

Hopefully some one starts selling it soon, im not as dedicated as you are :)

Whats the price of it now?

    • That was the first session so not a lot to take from the day. It was low 20s ambient and the coolant had got to 110 (and obviously had some pressure!) so that still needs to be addressed. I haven't downloaded the data yet but will. I had refilled the auto trans with Redline DT6 because it claimed the best viscosity I could find at 100o. It wasn't really long enough to get a good feel for that; while the trans got to 100o in the session it still wasn't shifting crisply as I hoped. I think I'll try a few more sessions before judging. No steering motor overheat but I'd hope not in only 1 session! But finally the suspension; it was night and day over the standard stuff and the car was a couple of seconds quicker on the same crappy tyres, which is a huge difference. I'll stick with that and get some sway bars and a mechanical diff sorted too and see how that all goes together
    • I guess it’s partially a compromise of how my car is used, wanting to be able to switch from drift to grip with track side on-car adjustment. Also partially with the way the knuckles are set there is more static camber but less dynamic camber gain. 
    • OK, so update from the track day on Friday It was a classic "an unfortunate series of events'. There were a few cars around and when i checked my mirror coming out of the fish hook I notice some smoke from the rear of mine. Looked again and it was getting much worse, I figured I'd blown a turbo or something to got off it and pulled off the racing line. However.... since it is a left hairpin into a right kink, I was on the inside of the next corner. There was a car passing me on the left and a big drop off over the ripple strip on the right......and someone had knocked the witch's hat that was on the apex about 1m onto the track. So, between those 3, I decided to mow down the cone and not damage my car/the other car. Right choice, but surprising result.  The car decided the cone was a small pedestrian so it blew the rear bonnet hinges up to protect their head in the upcoming person to car impact....I didn't see that coming and like an airbag deployment it happened super fast. Straight into the pits from there, everything was driving fine but it became clear it was a coolant leak not smoke, it was billowing up onto the windscreen. Onto the trailer and home. I'll do a separate thread about the repair (once I work out what it is ), but the immediate problem was the bonnet wouldn't open because the front was pinched onto the front bar and would not release. Ultimately we unbolted the hinge from the bonnet, pulled it back a little and it released from the front OK. "There's your problem", the top radiator hose had popped off at the radiator.
    • Yeah that looks like great caster, but I'd suggest trying less front camber some time and seeing if it helps with braking without reducing mid corner speed too much
    • I ended up setting the rear 5mm higher than normal to give some clearance.  My plan is to run the least camber I can in the rear which I think with the extra width is going to need to be -1.75 to -2.00° just to get clearance.  Guards have been rolled and pulled as much as they can/I would be wanting to.  front has the Acostal knuckle with the KPI change and the drop etc. So should be okay with the existing settings I have run with AR1s etc Front: Toe total -2mm(1mm out each side) Caster +7.5° Camber -3.8° Ackerman +15°
