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

[hypergear]

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.

I just bought one... now time to put it on and get it tuned!!

[kwickr33]

f*k thats pretty mad result for a CA. Thats the most responsive CA 316rwkws I've seen. Whats that in a Garrett range?

[SS8_Gohan]

Please list the full mods of what's been done to the CA

[hypergear]

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.

cat or decat?

[hypergear]

200 cell metal cat.

did an E85 tune Stao..

Can't hold boost. Reckon the OP6 is too small??

[hypergear]

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.

[SS8_Gohan]

anyone else running an OP6 rear Stao? want to compare boost curves

[SS8_Gohan]

did this car ever get a full tune done? interested to see the boost curve

you said this had the .63 rear housing

[hypergear]

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.

[SS8_Gohan]

how's the ATR43 differ to the OP6 ATR28G3 i've got?

and the .63 rear housing for my turbo, who makes those?

[hypergear]

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.

Since you got trent to tune it im assuming your local, where around the dandy/frankston area sells E85?

[SS8_Gohan]

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