Alright guys here is my dyno today done at Dyno-Pro in Colorado. I got to actually Dyno my own car which was really cool and fun!

498WHP and 516TQ!

Logs are in 4th gear running map 7 19.8psi on E50 fueling.

Mods:
VTT Stage 1 + Billet Wheel Upgrade
VTT Inlets
VTT PCV
Jb4 G5 ISO
BMS E85 BEF (stock knock tables)
Map 7 19.8PSI
Stage 2 LPFP
Hartge FMIC
VRSF DP
ETS CP & Synapse BOV
Stett Vacuum Canisters
BMS Cowl Filters
STOCK HPFP
ECS TwinTake

Take a look at the logs too and to say the least i am stoked!

SAE correction

Strong numbers especially in Colorado. Very nice

[Immoralus]

Niceeee 500 ain't bad at all.

[Chris@VargasTurboTech]

Nice! Especially at that elevation. Enjoy them!

[v8bait]

Poor laggy Colorado lol I remember that pain

[N54QC]

Those are really nice numbers IMO for your setup and elevation!

[Russjonesr]

Very nice numbers!

The correction factor value is conveniently invisible. The uncorrected numbers must be way less. What was the cf value?

[snelson3003]

1.22 CF.

SAE

[snelson3003]

And BNK everybody uses SAE numbers. At altitude this made 404whp.

A FBO e85 335xi on Cobb protune made 346whp before mine.

1.22 ouch. Had u posted the internet favorite STD correction u woulda broke 500 easy. Again props for posting SAE correction

[snelson3003]

SAE is the only way to be taken seriously.

There was a DocRace Single Turbo 335xi who made 430whp on 18psi and 91 octane.

He had tons of timing pulls though but his SAE correction was 1.24 and made 534whp.

[Rnm]

Pretty bad ass numbers. Enjoy the newfound power.

[snelson3003]

I probably have a little work to do on the timing since I dropped a few degrees over 6krpm and could add another 2psi to my boost curve.

But for now I'm stoked with my #'s and I've driven it like this for all 8K miles on map 7. Not a single issue other than some fueling gremlins lol.

This is clearly SAE correction, well over 500WHP with the STD the platform has decided is standard for some reason.

Steve, one thing I see, AFR are pretty darn lean, 13:1 is really on the edge, we honestly run 11.8:1-12:1 be careful with being that lean, and that timing. Car is running strong thats for sure, no corrections really to speak of, so the motor seems happy!

[snelson3003]

Yeah it is pretty lean, all I'm running is the BMS E85 BEF on map 7. I am told it targets 12.8 Afr top end so I'm a little leaner then that occasionally. Usually it's 12.7-12.9 both banks.

[bnk]

1.22 is more or less what it should be in Colorado.

It is always good to get the uncorrected figures to understand how much the car is really putting down.

Correction factors are calculated for NA cars. A turbo car can compensate for the less dense air to some degree. So a car with uncorrected 400whp and corrected 500whp at high altitude will put down a figure that is somewhere in between 400 and 500 at sea level.

[iminhell1]

Isn't the 4th gear also an issue?
or does the correction take that into account?

I thought 5th was the preferred gear for dyno numbers ...

[Beemin]

My experience is that at higher altitude SAE actually makes more power than STD. I made 2whp more with SAE at 4,500 ft. Numerous other dynojets at my altitude typically show STD slightly lower than SAE.

OP, do you have your STD numbers too? I'd be curious to see what it's like in Colorado.

[AbacusRacingN54]

Guys at sea level always increase their "altitude" for better numbers no matter what correction factor

SAE and STD differ only a percent point or so depending on the combination of the affecting factors. In this example it could be e.g.: real value 1.0, SAE 1.22, STD 1.23, so in extreme conditions the largest difference by far is in between the true output VS the standards.

[snelson3003]

Nope. Dyno-Pro didn't give me those #'s in STD. They all said they don't use STD anymore. Their SAE correction was based off sampling takes before the run each time.

And I did 2 4th gear pulls and 1 5th gear pull. All came out the same with the 4th gear pulls reading 5whp less.

[snelson3003]

This shop does local N54/N55 often and they all said the same thing. The prior record was some Hexon Turbos that made 489whp on meth and E35.
