How the hell did you take the tranny out on the ground???? Wow.

Very carefully? lol

Did you put meow to work? Who was underneath that thing?

[bigern45]

I've done it twice that way. Not easy.... Clearance was an issue.. Lol

[britishturbo]

Meow and a lot of others helped at various times.
i was under it most the time...

[jibberjive]

I was totally even with a Yamaha R1 1000cc bike driven by someone who knows how to ride...

Do you by chance know what year R1?

[britishturbo]

Do you by chance know what year R1?

I know it's a newer one.. I asked him waiting to see what he says. It's a friend of mine lol.

[britishturbo]

The bike in question stolen from his FB... lol

[britishturbo]

Do you by chance know what year R1?

It's either an 04 or 05 I understand.

[AudiForeman]

Looks identical to mine2004-2006. Absolute monster at wot. I have done 186 on mine wish ease and it gets there quick. Very impressive for your s4 to be that close. 1000cc bikes are no joke, can't wait to see this thing 100% done.

[jibberjive]

Nice. Liter bikes are a tough call for any car, impressive that you could even hang.

2.1 FATS time this morning at 35psi.
I'll post video and plots later :-)

[britishturbo]

The 2.1 time was slightly up hill...
I was setup for a flat run on my normal spot on I-80 but when I got on it realized ESP was still on... so it started freaking out and pulled a bunch of timing so it "only" managed a 2.2 time lol.
I think it might hit a 2.0 on flat road... crazy shit.

[britishturbo]

Here ya go... I'll upload video soon

[britishturbo]

And because we all love the G's...

[Monty23]

OH MY GAWD! Good work BT...

[AudiSportB5S4]

Damn! Looking forward to the track.. If this car traps decently well, you'll have the most complete S4 build thread ever!

Also great job with all that dedication to get that tranny swapped on the ground lol..

[Monty23]

Are those logs without nitrous?

[britishturbo]

Are those logs without nitrous?

With 50 shot :-)

[AudiSportB5S4]

50 ounces of spool aid.

[getslideways]

Are you still on schedule to hit the dyno and track this week/weekend?

[britishturbo]

Are you still on schedule to hit the dyno and track this week/weekend?

Not sure... I have to take a day and a half off of work this week already so I don't know...
If anything maybe I'll at least make the track lol.

[bigern45]

nitrous the entire pull?? or programmed early and lets off at a certain rpm??

The window switch is set for 3500 to 5500.

[britishturbo]

Here's Virtual Dyno overlays:

Blue is 32psi with No Nitrous (2.38 FATS)
Red is 35psi with Nitrous (2.12 FATS)

Crazy stuff lol

[NOTORIOUS VR]

can you add a boost plot to that? Is the boost falling that hard past peak TQ? With your size turbo, you should try to keep increasing boost after peak TQ to keep it as flat as possible.

[Monty23]

You going to taper that boost up to hold the power up top?

boost plot is up a few posts

You can see in the pic above that it dropped off about 2psi...
I haven't got the Wastegate dialed in for 35psi yet so it's no big deal lol.

[Meow]

The window switch is set for 3500 to 5500.

I like this! Shutting off at 10psi was too early.

Watching the air intake temps when the nitrous hit was funny too, had like a 35 degree drop or something when the nitrous came on.

It was an epic weekend pulling the trans on the ground, doing racewars and meeting all the PA guys.




we got filthly too...

[NOTORIOUS VR]

FWIW, here is gearheads 770 dyno... on a 2.7L (2.1 FATS)..

this is the curve I'd like to see from your setup. It would be killer. Yes I know he is missing about 1k RPM compared to you :)

Yeah he's got me on torque down low (4000) but over 5000 I think I'm higher everywhere by the looks of it...

yeah... you definately peak much higher... but that last 1k RPM (7-8) needs moAr bewst ;)

Ha next rev... just for you lol

[jibberjive]

And because we all love the G's...

Are the 'vehicle settings' in ECUxPlot all untouched?

[britishturbo]

Are the 'vehicle settings' in ECUxPlot all untouched?

Only thing I changed was the RPM per MPH was changed to reflect reality.
Here's my settings:

Mass (kg): 1700
RPM per mph: 68.11
Coef of drag: 0.31
Frontal Area: 2.034
Driveline loss: 25

[britishturbo]

I haven't done a 60 to 130 test yet but the fats run this morning showed a 6.1 second time for 60 to 125.
But that was with short shifting from 4th to 5th so I'm sure it could do better.

[shorterthanrich]

Excited to see V-box times eventually!

[britishturbo]

Video from this morning.
You can't see the cluster much at all though thanks to the sun... grrrr
You get the idea though lol.
