So my r32 gts-t with rb25det got written off last year, got $10k from insurance somehow so I went to the dark side and bought a 2008 BF XR6T for $12.5k, anyway $5k later and it's making this power! This is K.P.Ms "flywheel figure" the real rwkw is about 320rwkw but this shows the curve. 380rwkw is doable on E85 and more boost.

FMIC, 1000cc ID, clutch, fuel pump, 4" dump & cat, custom tune, stock twin 2.25 from cat back, 265x18 rims

It is laggier response wise than the 25det with a 260kw highflow due to the GT35 being pretty big from the factory however full boost and torque at 3k rpm cannot be beat. Sounds awesome and it will make this power on the stock turbo and motor all day long with 200,000 kms on it.

So yeah, if you are thinking about going to the dark side let me tell you it is absolutely worth it for bang for buck! Also having all the creature comforts of a car that is 17 years newer really is nice, electric seats, leather, ABS, airbags, massive interior, cops don't look at it twice either! Around the hills it handles the same as my GTS-T, obviously one the track it isn't going to be as good due to having almost 400kg on the 32.

"flywheel kilowatts". Why not print it out in HP, then it will seem even bigger. Estimating "flywheel kilowatts" is like measuring your dick at 4" and estimating it up to 6" based on losing a bit between your nuts and your arsehole.

If it was actually on an engine dyno and MEASURED, then that's different.

Having taken the time to bag you though, XR6T is a decent package and easy to make power from given they're only running 4psi standard. I'm glad you're happy with it. But it's a red flag to a bull posting that sort of thing around here :)

I do like trolling. Forged internals, 4L and GT35 from the factory makes for about the best value motor you can get. It'll pass a roadworthy inspection every time, I also am far less likely to die when I put it into a tree due to the ABS, airbags and much higher safety rating.

ABS wont help you after you have hit a tree

Might help me avoid hitting it though! I tested it out in the wet and it works a treat with the DSC, can stomp on the brakes whilst turning hard and not only will it not lock up, it will still steer fine as well, 4 wheel braking is pretty cool.

    • For once a good news  It needed to be adjusted by that one nut and it is ok  At least something was easy But thank you very much for help. But a small issue is now(gearbox) that when the car is stationary you can hear "clinking" from gearbox so some of the bearing is 100% not that happy... It goes away once you push clutch so it is 100% gearbox. Just if you know...what that bearing could be? It sounding like "spun bearing" but it is louder.
    • Yeah, that's fine**. But the numbers you came up with are just wrong. Try it for yourself. Put in any voltage from the possible range and see what result you get. You get nonsense. ** When I say "fine", I mean, it's still shit. The very simple linear formula (slope & intercept) is shit for a sensor with a non-linear response. This is the curve, from your data above. Look at the CURVE! It's only really linear between about 30 and 90 °C. And if you used only that range to define a curve, it would be great. But you would go more and more wrong as you went to higher temps. And that is why the slope & intercept found when you use 50 and 150 as the end points is so bad halfway between those points. The real curve is a long way below the linear curve which just zips straight between the end points, like this one. You could probably use the same slope and a lower intercept, to move that straight line down, and spread the error out. But you would 5-10°C off in a lot of places. You'd need to say what temperature range you really wanted to be most right - say, 100 to 130, and plop the line closest to teh real curve in that region, which would make it quite wrong down at the lower temperatures. Let me just say that HPTuners are not being realistic in only allowing for a simple linear curve. 
    • I feel I should re-iterate. The above picture is the only option available in the software and the blurb from HP Tuners I quoted earlier is the only way to add data to it and that's the description they offer as to how to figure it out. The only fields available is the blank box after (Input/ ) and the box right before = Output. Those are the only numbers that can be entered.
    • No, your formula is arse backwards. Mine is totally different to yours, and is the one I said was bang on at 50 and 150. I'll put your data into Excel (actually it already is, chart it and fit a linear fit to it, aiming to make it evenly wrong across the whole span. But not now. Other things to do first.
    • God damnit. The only option I actually have in the software is the one that is screenshotted. I am glad that I at least got it right... for those two points. Would it actually change anything if I chose/used 80C and 120C as the two points instead? My brain wants to imagine the formula put into HPtuners would be the same equation, otherwise none of this makes sense to me, unless: 1) The formula you put into VCM Scanner/HPTuners is always linear 2) The two points/input pairs are only arbitrary to choose (as the documentation implies) IF the actual scaling of the sensor is linear. then 3) If the scaling is not linear, the two points you choose matter a great deal, because the formula will draw a line between those two points only.
