Lol how often does someone have 104 octane available?

[ALAN12186]

Where is the cooler info?

[S4Flyer]

In for stock numbers on same dyno. haha....

Even on 91 octane, that's awesome

def unnecessary, just trying to stay relevant...

I'm just saying it's kinda tricks the uneducated customer who says "my car makes almost 600" lol on race gas. I haven't seen a pump that has more than 95 octane on the street. Still not trying to bash tho

[skiptowncat]

I want to see the independant figures for 93 and stock downpipes

Edit: is that showing 407 to the wheels? If so there really is something funky going on!!

It did 536 HP on 91 octane.

Many of us run an E85 blend to achieve higher octane levels approaching 100 or so. Both on the street and at the track. At the dragstrip and road tracks, 104 is widely available. That is the venue that people want the most HP, at the track?

I would like to see 93 octane numbers because I think that is the most common (excluding west coast, Colorado, ect...)

Also, if you are shooting for king of the hill, stating max HP numbers, it would be foolish not to include 104. Makes perfect sense to me?

Yeah, my guess is stock was CHP adjusted 400hp lol

Yeah, that's needed

I run 104 (Sunoco GT260+) quite a bit, and pretty much exclusively at the track so I like seeing the numbers. Stock numbers on the same dyno would be nice, but there are plenty of good reference points there that show some pretty awesome gains.

Even if you want to take away the 104 numbers, the progression from single pulley to dual pulley to ultra gaining 70hp/tq (and a lot of tq in the low to midrange) is pretty impressive. The real question for me is if the ultra part, which by all accounts is 25-30hp, is worth an additional $1600 over what just the dual pulley gains.

which of that fairly extensive list of mods is the "Best 3.0 TFSI mod ever"?

[Mat@1975]

Hummm.....

158 HP of loss (difference between WHP and CHP) seems to indicate that the runs on the dyno had been carried out in 6th gear in my opinion.

(My personnal experience is ~125 HP of loss in 5th, and ~ 80 HP in 4th)

I can also tell that the more high is the gear, the more optimistic HP number is given. If these numbers had been obtained in 6th gear, you can roughly substract a good 10 % to have the equivalent power number in 4th (which is more traditionnal)

I also regret the absence of a stock Baseline.

Ultracharger.

MPH is listed on the graph. Should be able to figure out the gearing from that (roughly). Typically 4th. MAHA does wheel way lower than others, and it varys from dyno to dyno while crank seems to remain consistent.

Regardless, numbers listed show the gains from each stage. Which was the point.

I'll see if I can get stock from the same car.

[Audibot]

So.... 93 octane? Not that I have an S4 (much less a B8) but interested to see the #. Especially since the East Coast is rife with 93

They only get 91 out there in Arizona. 93 is better though. :)

Fair enough... different dyno, different experience...

There is way more interest in being able to run E85 than there is 100+ octane levels. It would be one thing if we had program switching that would allow us to run a 91/93 file on the way to the track and then top off with 104 once there and load the 104 file.

Arguably, the best APR mod at this point (promised over and over again) would be program switching. E85 file would be the icing...

[jl87]

^ yes please

[Rez90]

this engine hp or wheel hp? assuming engine hp......

or is this measured in whp and then 15% added?

[Audibot]

Touche.

[Arin@APR]

MAHA reports crank. It's what used in Germany for TUV testing.

[fitzydude]

Awesome, now take it to the track!!

The MAHA reads wheel and does a parasitic loss procedure and estimates crank. As you can see above, they measured 408 hp at the wheels and corrected it to 596 crank horsepower. Now keep in mind just because they measured 408whp does not mean you would read the same 408whp on a mustang dyno on the same car. The MAHA made read lower than many... more like a dyno dynamics.

LMAO.. And the skeptics are present!!

Better get those traps, Arin.. Then let them dissect how the traps aren't legit..

[Arin@APR]

I've seen 123 MPH at 1200 DA. Hope to see more!

Where and when did this supposed argument over traps speeds take place? DA has very little impact on forced induction cars (regarding trap speeds) and I don't ever recall seeing someone disputing a trap speed that was backed up by a slip.

There is a reason people are skeptical on here, as a whole. Too many broken promises and missed deadlines in the past and most know that you can't take certain things at face value anymore without valid proof. In this case, I don't think anyone would argue a time slip as not being valid. The debate would then only be if a car was gutted or not, but that's entirely different than debating trap speeds, which can all be corroborated and corrected for altitude/DA.... Handy

Those r some numbers right there. Very nice!

[Hofahome]

Cool numbers but not very useful. Need drivetrain loss %.

Just ribbing everyone who is all in a frenzy...

In this thread alone:
Don't dyno on pump gas
Don't use MAHA
Don't use crank figures
Don't use 91 octane

It's just all of the skeptics like we're "owed" something.. Even your response "too many broken promises" like this is a fucking marriage.. You guys are hilarious.. WAY too serious.. Is the car fast? Yes? Great! And now someone will quote this and say "If I'm going to invest my hard earned money I want to know that XXXXXXXXXX" and there will be some magical formula that is important to them..

It's all comedic. No one is ever happy in Audi land.

That's the most promising stat right there!

This guy gets it. How many other tuners here post random dynos (Maha?) and then report the adjusted numbers? None.

You can't debate whether a trap was real or not, but you sure can debate how it happened (light weight wheels, light weight rotors, drag slicks, gutted interior). All of that could be good for setting a record.

I will judge the setup once I run against a local one, full weight against full weight. Until then I'll assume it's a FANTASTIC upgrade for anyone ALREADY running APR. No, that's not sarcasm. I would upgrade if I were an APR customer.
