Ng900 513whp sae in Denver

I put the ng900 on the dyno with slipping clutch anyway to see what was going on and it made about 10whp more than before with other tune and it was about 30F hotter this time.

I have a 4th gear video too, you can hear the clutch let go.

Nice That is exactly what we need, we could slip the clutch when we want, not when we do not want

Looks like maybe a multi-plate clutch setup.
So John what's the story withthe clutch, is it just slipping or is it shot?

I guess I was not clear on that, I said it let go, I meant when its holding ,its holding, when its no longer holding, its let go

If you listen to the second run, that was only about 4500rpm when it let loose and slipped and I got off the throttle... It is slipping bad now...

Slips in second bad and slips in third and fourth.

John

Here is the dyno sheets

Seemed to pull longer into the rpm band once I tuned it.

These two run are back to back, not wait time.

Ok, here is an overlay from last dyno at 36F and light snow and today, summer, but morning. You can see the spool-up difference, mainly because of temp, I have the boost coming up as soon as it physically can, then you can see it holds the power past 6k much better, its actually about 20whp it looks like on my graph with less detonation, smoother line, plus the knock counter did not go off at all, still at 0, 10 is still considered good and 80 is where it starts to get bad.

Nice John-self tuned as well that's awesome. Gives us all something to strive for.
Where's the knock counter? Is that part of trionic 5 or T5suite?

Oh man, one word... HOT!

I'm sorry to hear about the slipping clutch, but its always a good excuse for an upgrade .

Haha, my poor stock 185hp NG convertible must have shat itself as the rumble of your exhaust echoed through my house!

Yea, when you hook up the canbus, its like having a tech2 hooked up to the car you can tune with! You can watch where in the fuel map the ecu is going to and in the timing table and you can monitor everything, tps, iat, coolant temp, fuel, timing, injection rate, knock level, timing retard map, knock fuel map. Any map that is in the ecu, you can monitor it and every sensor in the car, you can monitor it live.

I had big gages on my screen with iat, coolant temp, boost, knock and I was watching the timing map on the screen and watching a/f on my wide-band and we had wide-band on the dyno.

If the ecu starts to pick up knock, you will see the level of that knock and it also gives a peak, current value and minimum if applicable. I can go drive, pull over and see what the max boost request was, what it actually achieved, etc.

No knock level was detected at all...

What was really cool is I was watching iat, it was at 38c as I drove down the road, I would go wot and the w/m injection would come on and the iat would drop to 20c Very cool.... I don't know if you saw the video of Daveship? His dyno graph showed bad detonation in my opinion, very squiggly line, usually means detonation....

nice numbers.

in all honesty ive never seen a car come off that backstreet dyno with a smooth plot its something else not detonation in my opinion...seen cars of all softwares on there over the past few years (been the same dyno every year for awhile now)

I thought you had you w/m nozzle after the MAT sensor?

Monitoring gauges on real time is ofcourse nice GUI stuff, but dont offer much in terms of tuning, when you cannot pick up all the needed info at one eye blink when rpm is sweeping.
Seems that progress has been made, but I would like to see the non SAE curves as well to se how much gain was obtained regarless of different temp, humidity etc since as you say the w/m removes heat thus its used to increase the sae factor.

Wicked. I guess I would find that to be undrivable in FWD config. What do you do, just chase down Lambos on the highway? It'd be too much for track purposes. I'm not hating at all, it's really impressive, but there is a point of diminishing returns on a FWD car.

Power levels can be changed I can set it up for drag, current set-up, drag radials and slicks and well prepped track do wonders for traction.

I am going to a road race event in Sept, I will turn down the boost and tune it right to the edge of traction for that event

Here is a video of what its like driving it, before the road tune.
