Dynoed our RS5, stock. Anyone interested in the results?

B8 S4

Bear…stages don’t exist on all motor cars…

There is just bolt ons or power adder added

Fastest stock is 12.75@108.36
Fastest bolt ons is 12.28@112.45
Fastest power adder is 11.41@125

As Meistah said the 1226 car wasn’t even tuned but was on race fuel which is frankly as irrelevant to me as stripping your interior. Interesting but not a benchmark as it is not street.

Start a new thread for this though.we should be talking about three rs5. I mentioned rs4 stuff to I because of the engine also being the high revving 4.2 fsi and we don’t have any modded rs5 info yet.

That Russian stuff is a joke by the way. Primetime and I referenced it in a thread here already.

Yeah Saki, it must be ridiculous to compare with the B8 S4 in this forum…:slight_smile:

Do you really run the 1/4 with NO changes? Street tire pressures, full tank of gas, AC on, all the crap still in the car? I actually don’t remember. Besides, just because you don’t care for race gas, doesn’t mean everyone feels the same way - and in the S4 the difference is massive. No, there will not be such a big difference in a NA car, a little ignition timing advance, but not nearly as much as in a FI car. I don’t do impromptu racing…even for the trips to Mexico, there is always some prep involved, of which there is plenty of time to switch to race gas (and yes I now have a rig I can siphon my gas out safely and quickly).

As it sits, it would be difficult to get that RS5 anywhere near S4 100 octane performance, without a power adder. It’s already pretty much tapped out as it comes from the factory.

Anyhow, I’m not sure how much more there is to talk about the RS5, until someone here picks one up.

Meh don’t care about race gas

We are not in a drag car…we are measuring our street cars
So why not run in full street mode.?

If a car needs race gas to be fast that’s not for me.

As for the na car not benefiting, and the supercharged car doing so, I don’t see it as such a huge difference on the high revving 4.2. You picked up what…two mph or two tenths?

Arin, can you add in the pbox data?

Also I wanted you to know that PBOX data is usually optimistic on the screen, but the data file that is saved to the SD CARD will have the truth hidden in it.

If you want to go re-test it and then go from the car data, that would be far more valuable for the various forums. It will highlight the elevation changes you referred to, and will allow you to ensure that you are not shortchanging your delta on re-test because you ran on a different part of the road etc.

It would also ensure the integrity of the data can’t be called into question if you make full disclosure a policy by emailing that file out to someone like me or TSIVAS with PBOX experience.

An RS5 owner tried LC on his car… Unfortunately, it doesn’t look to work any better than that of the S4 LC, granted it revs to 4.5K-5K but still has the dealy after you let off the brake… He is going 18mph before the revs start to move forward quickly…

Arin, Does the RS5 you guys have exhibit the same behavior?

I missed this (and the forum did too)

Let me know if you ever want to make a vid of some sort. I’m always up for it. Would be cool to have you race my buddy’s MT6 car which is also bone stock.
