So I went on a dyno...

I’ve heard some say the AC switches off at WOT and I’ve heard some say it stays on. BUT every time I see a dyno run of our cars doing a AC on vs AC off run the AC off run is better. One Example

Looks to me like you’re pretty much on point with AC on and running piggies.

meh. You dyno’d about 275/275 which is normal for a barely modded tip car. The tips usually dyno down in the 240-250whp/235-245 wtq range.

All you have is tune piggies and catback … so I think the numbers are just about right. Hopefully justincredible chimes in.

Again though, an E92 M3 that was 414 crank hp dyno’d 320 whp. That’s 23% drivetrain loss…on a RWD car. If you apply an AWD premium of say 4% to that, and make it 27%, coderedpl’s 275 numbers mean he’s around 370 crank hp/370 crank torque. That’s 30 crank hp and 68 crank torque over stock.

also,l I don['t know how the fuck you dyno a tip. I tried to log one and it was a pain in the arse. Thing was kicking down all the time. Only if you got into it 100% wot starting at like 4500 would it let you push to redline without kicking down.

^^^Yeah. Apparently, DSG B8 S4s kickdown on the dyno as well.

I believe he had it in tip, it goes up pretty high before switching, but as long as you don’t press it all the way down to the button it shouldn’t kick-down.

I guess with the A/C off I would probably/maybe get up to the 280 range or maybe a dead even 275. Either way, if that’s what I should expect, than fine, means my car is running good.

are you sure it was WOT and not 92%?

anyway, didn’t you read my post above? if an E92 M3 is 45 whp more than you, that’s about right. Was he DCT or whatever they call it? Or manual?

I’m 100% sure it kicks off. When I was trying to figure out what is wrong with my a/c last summer, it would kick off every time the pedal hit somewhere around 80%? I didn’t check what RPM it kicks off at if you aren’t at the throttle threshold for that to turn it off. I bet it’s somewhere around 4500

Can’t say for sure as I didn’t really look at the gauges, i was too busy admiring the exhaust tone lol

Yea it sounds about right I get that.
M3 was auto

Was at tach motorsports also yesterday…

Temps were 63F, elevation was 5 ft, pressure was 29.5 inches hg, humidity was 73.1%.

Came a little later and here are some other cars that ran.

B8 S5 6 speed with awe tuning track exhaust and apr intake… 280 whp in fourth gear.

Stock B8 S4 DSG…312 whp (fourth gear)

GIAC stage 1 B8 S4 DSG… 370 whp (also fourth)

They all had trouble with the torque reading.

M3 was DCT with an axle back and some hack tune. Put down stock numbers - about what other stock m3s get on Dynojet.

Some pulls with an RS4 vs same M3 (plus passenger) later that night had RS4 ahead by about ~2 cars.

Rs4 had intake spacers, k&n, ecs h pipe, Jhm lw fw and stage 4 clutch, and Jhm lw rotors.

lol - Tony ran the M3 (+ passenger) and put two car lengths on him?

Ya so he says. I was up front spotting for them. When we got together after- m3 guy was impressed.

They did a few runs.

Interesting, what speed did they go to? Typically it is the other way round, especially with a DCT car.

Nice.

Tony can drive. Get to the strip with him and ny07rs4 tsivas. All first timers in these respective cars, so you guys will have fun, and learn from each other etc.

I[quote=BenSTi]interesting, what speed did they go to? Typically it is the other way round, especially with a DCT car.

Maybe that’s how it goes (rs4 always losing/running 13s) on qw lol. If someone can drive reasonably well, the rs4 is very capable.

Go watch the videos of my rs4 walking the e93 m3 dct and the c63. You don’t always have to lose Ben.

Yeah he can for sure. He placed second in his group on his first autocross ever. Got him hooked.

Did tony dyno there with these cars? Or was he just hanging out?

Interestingly an RS4 with a very similar modlist to his just ran 12.26 @ 112.98 mph. No tune, no catback, just lw rotors (all 4), lw flywheel, clutch, and lw front seats. He used 98 octane. Guy is getting lw wheels and a tune soon. Should be interesting. 11s with bolt ons?

That car went 12.84 @ 107.9 stock on 93. Same track s-quattro-4 went 12.69 stock…then 12.47 with Revo93/awe catback/strat intake.

Seems that perceived inability of the rs4 to respond to mods will need to be shoved in the toilet. Now that some guys who like the strip are getting the cars, they’re no longer ‘underachieving’.

Add in the tts sc RS4 going 11.41@125 on 93 (fastest pump gas time…for any Audi) and its looking a lot different than it did even 12 months ago when I used to get into so many arguments with b8 guys who said the 4.2 rs4 was ‘fail’ lol.

Saki- no he didn’t dyno.

I’ll say my prediction now - an RS4 with the TTS or JHM or possibly AMD S/C’r + the right supporting mods and the right driver in an ideal environment. High tens. If I’m wrong so be it but it is starting to look like that is a very real possibility.

not out on a limb there NY. That last half a second is extremely tough (from 11.4 to 10.9) but I think lots of people are expecting to see something amazing from these cars. If they do it on pump gas, that will be hilarious.
