Some more interesting Results. I found this on NS. which I believe the torque is abit funny. Its a GT2871R on a worked SR20det with Greddy cams made 280rwkws (highest GT2871R results I ever seen). This would be a back to back comparison of ATR28 CA18 VS GT2871R SR20

I spoted above power curve into ATR28 CA's dyno sheet:

I know this has been mentioned a couple of times but what about a series II skyline turbo highflowed from hypergear? what do you guys reckon? i might do it, but the thing is its hard for me to take off the turbo... mayb alot of wd40 might help.. :)

be good to see how the sr20 would go with the atr28, should be as responsive as the 2871 but make a healthier power curve

I've never seen GT2871R making 280rwkws before. ATR28G3 on the same car same dyno should make around 320rwkws.

the operator has just printed the wrong torque graph, he has printed tractive effort not actual torque.

as for 280rwkw out of a GT2871R..... there is no way i can think of to crack that power without E85.

87.6mm stroker cranks due around April :-)

Its good to see some guys finally giving the mighty CA a wrap...id love to build a tough one of these.

I think with the right headwork i could get it to match that SR down low.

Someone surely wants one built....2rismo...go and buy one.

    • The car remains in paint jail. I am now pretty convinced that the whole "RB25 Airboxes are kinda limiting to ~300kw" could be a thing. Also saw a good video from Engine Masters: (Sorry for FB link) (https://www.facebook.com/watch/?ref=search&v=761771519471924&external_log_id=c10bcbb6-2c39-4ff3-9240-287e9921fde6&q=Cold Air Considerations) Where they tested Pod Filter sizes and kept adding bends to a LS3 on an Engine Dyno to find if bends caused power loss. It's a good video worth watching - They did lose ~25hp from making an intake which had 3x90's and a 120 degree. They only lost maybe 1hp with a basic 90. I feel that by sealing up my airbox I have: 1) Created the same restriction a stock airbox would have. 2) Created a very convoluted set of intake 'pipes' by forcing all the air through the ducts. So I am pretty confident I'll be going full circle and have a huge hot air intake pod and actually see a benefit. The air does *not* stay hot once it gets flowing, aided by the ducts, and the pod can then pull air from anywhere. All the posts of yore talk about the stock airbox costing 10-15kw at 300kw+ but you know what? I f**king would very much like that 10-15kw and I remember my own pod filter in engine bay experiences. Turns out the GTT Reo and Headlight brackets really don't allow you to mount GTR items, no matter what the internet says. Various brackets have had to be made up to actually make it fit right for the front bar. Also some idiot mounted a 3L Accusump right where the bumper wants to go, so that has had to be 'relocated' To where, I am still not sure, but it's supposedly mounted in the pictures and I can't see it.
    • Sounds like the oil pressure light is wired into the oil temp sensor... As it warms up, resistance on temp sensor reduces, hence more current can flow and the dash light gets brighter.
    • Got the front subframe and suspension in.    
    • If it's cold in summer, then no issue. If it's cutting out every few seconds and you're not reaching your target temp, then there's an issue. One could be the pressure switch and the other issue could be the temp probe inside the evaporator.
