Got my SAFC 2 installed and tuned along with a front mount and new fuel pump.

Tuned by Hitman (Matt) in Penrith.

Car made 217rwkw which was quite suprising, I was expecting more like 190 ish.

Matt seemed to think it was abnormally high as well and that my turbo might be abit of a freak. Either that or a happy dyno :( Either way, even if its actually making 50rwkw it still feels significantly quicker which is the main thing.

Running 11psi.

My only concern is the knock reading im seeing on the SAFC, Im thinking tomorrow im going to try re-set the SAFC's knock reading or something. Because it read like 250 at one point which just seems crazy high, however at no point did I hear anything even remotely like pinging nor did the car miss a beat.

A/F ratio seems safe enough, averaging 12:1

I would think that if it actually WAS pining that high I would have A: Heard it and B: Be crying over a dead engine right about now.

Reads around 10 or so on idle or just cruising so I dunno. I think ill call matt tomorrow and ask about it.

But yeah, pretty happy, Matt was very good to deal with and like I said, I can definetly notice the extra power, especially in 3rd.

Nah, to be safe matt assumed it was the stock turbo and didn't bump it above 11psi. If it is the stocko theres no sense in risking it. Will be interesting if it is a highflow, previous owner never mentioned it.

More just wondering about that knock reading. I mean given my Air/Fuel ratio's and the fact that I could neither hear nor feel any sign of pinging, the reading of 250 would have to be wrong yeah? It didn't just read that once, read above 200 at one point and like 170 earlier on. Its possible that its just been calibrated wrong? Or a faulty knock sensor? Corect me if im wrong but I should get some sort of warning light on the dash at high knock levels yeah?

217 at 11 psi isn't a standard turbo. It makes that power at 14-15 psi.

most likely its a highflow. 217 at 11 psi sounds spot on for a highflow.

its either a high flow, or the dyno is happy by about 20rwkw.

Correct, if you have such a high knock count your engine warning light should come on. As for the knock count itself, hmmm seems interesting as that is a freaking high knock count for there to be no sign of damage. I would just reset the knock count to zero, take the car out for a slash (give it a bit up to redline) and see what the knock count is, if its not that high anymore than i wouldnt worry about it :)

      Hypergear ATR45 SAT Turbo With addons (brand new - never used)

      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!

      Hypergear ATR45 SAT Turbo With addons (brand new - never used)

      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!
