Cubes: the timing throught the rpm is constantly being changed by the CAS right? so to move the CAS all the way to the right would be a stupid thing to do? Is this going to reduce the retard adjustment therefore these cell points will be up to sh*t. Or even bring the timing before 10deg.

What he most probably did was increase fuel pressure, adjust the safc so it wasn't running rich, then retarded the ignition timing via the cas so it doesn't ping.

The cas is a set value, the ecu's map is also set but vary's with load and rpm.

Think of the cas as a base ignition value that makes global a global set change to the internal map.

ever seen dyno graphs where the cars power drops off after around 5500rpm ish? its cos theres too much back pressure on the exhaust

yeah I just saw you graphs I notice the difference when you got the split dump and the GTR fuel pump. The big drop off turned into flat... Well can't argue with that!!

    • Yeah pretty impressive hey, good to see quality products not over-shooting their prices. That's what drew me to buy the hypergear turbo, just a shame I've never got the chance to see it in action
    • Thank you GTSBoy and MBS206 I have done the compression test with the motor out of the vehicle, reason for the test was to see if I needed to remove the head and do rings etc while its out. I'm in the process of respraying the vehicle and tidying up a few things. Story behind it all is I've just purchased the skyline and it was running when I got it, never drove it on the street though as I wanted to pull it down and do it all up again before registering it. the gentleman I purchased it from told me the motor has a forged bottom end and has a decent tune through it but I was going to pull the sump off anyway to see if it is a forged bottom end. that's why I thought id do a compression test beforehand. 
    • Man, I'm kind of amazed that the price of the turbo has not changed in 7 years. Everything else is inflating beyond reason, but not this? Good on Tao / hypergear I guess? Anyways, good luck with the sale!
    • I'm selling my brand new, in the box, never used Hypergear ATR45 - and I had some additions I paid for a few yrs back when I purchased it. Never ended up having the rest of the money to add all the mods at once, so I just ended up slowly selling each part. I originally had it internally gated, with the dump pipe, however I found it was incompatible with what I was going to use it for, so I contacted (I think Ken) from Hypergear, and he and I messaged back and forth & he got me to ship the turbo back, where they modified it & made it externally gated, and gave me the 5 bolt dump pipe attachment for custom welding. (Photos below) This turbo like I said has never touched the inside of an engine bay, it's completely brand new, never used, been sitting in the same box it arrived in, covered in plastic & all. Below are the photos of it: And while the guys at Hypergear were making it in-shop, they sent me some photos of the process: I'm looking at selling this just because I'm in need of the money right now, and don't have plans on modifying the 34 anytime soon - and from reviews & peformance sheets, this turbo had amazing results back when I was researching. The turbo was purchased in 2018 for $1.9k, with the mods I got added on. Looking at the website now, for the same turbo they sell (ATR45SAT), with the current addons it adds up to $1830 for the turbo Current addons included: - Bolted dump adaptor - Ball bearing CHRA - Braided oil feeding line So I'm looking to possibly sell it for around $1800, with shipping included in that 1.8k, It cost me around $120 to ship - so yeah thought I'd throw it out there and see if anyone was interested in purchasing. Cheers!
