Tuned up the sr20 yesterday ready for the drags.

21psi pulled 328kw

30psi pulled 385kw

5558 .6 44mm external gate, poncams and forged motor

Theres is more in it but ringing the poor little things neck.

Unfortunately drags got cancelled due to the weather so thats for another day.

Thats a lot of power for a 2L on 21psi, is that on E85 though? Hey Mick O hurry up already with the nats, I cant wait to slap my one on lol..

Yes ethanol. No way would i push 30psi with 98 pootrol

Finally got some numbers but its not done yet,

On the New motor, with the 6262 .84 TS BB CEA.

Run-in tune (super safe) verylow/negative timing, 9-10 psi. 210-220 rwkw.

Turbo is super responsive and perky even with the timing so low, I noticed instantly its very throttle responsive, its very possible my intake setup helps in this regard. But the way it moves the air so quickly I have a good feeling this setup will be pretty decent on the 30/25 with vct!

One noticable characteristic.. the turbo seems very loud. even on low boost. however i am moving from lowmount to high mount during this build, so that might be why i think that.

will be doing real tuning next week if all continues well. Will post numbers as promised when its done. Unfortunently still running hte PFC and Tomei Z32 as no one has purchased the gear yet.

-dale

results yet?

Big boy turbo, wha happened to wanting response lol

Yeah, things got a bit out of hand with the engine build and from what I have seen so far this turbo should still have good enough response yet make massive power. Its either this or the 6266. Will see how we go.

I have a 6466 on an rb28, and i expect in excess of 500awkw. Might be a little bit too extreme on a daily strees sil. Buut, look at PJ's THING, because thats what it is, a freakish THING. It has a monster and still makes powers that are usuable for speeding up the rotation of the earth arouns the axis of the suns, and stuff

I think it will be OK.

There's a 180sx 2.0 VE non VVL, with a 6466 that made 536rwk@34psi with quite reasonable response.

Then there's James NFI's S15 2.3 VE VVL, with a 6262 that made 430rwk@24psi with ballistic response (but yet to have final tune).

With my motor 2.2 VE VVL I figure the next size above from James should still provide enough response yet be able to make 450-500rwk should we choose to push it that far.

It will be either a 6266 or a 6466.

Hahaha I laughed pretty hard when I read that! Pretty deep!

Allan, the 6466 on your 26 will be fine and will comfortably make the power ;)

    • 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.
