Most of you probably know what has been going on the past few months. I won't spare you the details with how my tune came to be (PM me and we'll chat). Lets try to keep that out of this thread.
Last Wednesday I ventured down to AutoSpeed Performance in South New Jersey to pick up my Avant. I arrived and the Avant was still on the dyno and Mark was finishing up my race fuel file. We unstrapped 'her and went for a ride with some 109 in the tank. OMFG! The car pulled hard. Power is very smooth and feels linear (as the chart shows). It was hard for me to stop at a BP and put 93octane in the tank.
My impressions after driving it for a few days:
Idle is spot on and very smooth on both 109 and 93. Cold starts and hot restarts are as if the car was 100% bone stock. Fires up within one crank of the engine. Part throttle response is impressive. This car is extremely street-able and drives so smoothly. Step on it in any gear and the Avant takes off. Launch in 1st gear and redline arrives rather quickly. This is exactly what I was looking for when I set out to build my car to its current state. The numbers are what they are. I really care about how the car drives on the street and its pretty impressive. Mark showed me dyno graphs from a 30minute window. We overlayed all of them and they are ontop of each other. IATs only creep into the 30C range. Can you say repeatable power?
Engine:
2.0L stroker motor machined and built by QED-Power
- AMU (06A casting) block and cylinder head
- AEG 92.8mm stroke crank
- Supertech 82.5mm bore forged pistons
- Scat forged connecting rods
- OEM main bearings
- OEM oil pump
- OEM timing belt kit w/ metal impeller water pump
- Supertech Inconel Exhaust valves
- Supertech valve guides
- OEM intake valves
- OEM hydraulic lifters
- Cat Cams 3651 camshafts
- OEM exhaust cam TB gear
- basic valve seat grind/lap
Forced induction:
- Garrett GT2871R turbocharger (.64 A/R turbine)
- ASP GT28RS hardware kit (cast manifold, 200cell HFC/Downpipe, braided stainless steel turbo oil & coolant lines, 630cc injectors, 3" MAF housing w/ 1.8T sensor, ASP silicon TIP, ITG air filter)
- ASP FMIC
- Exhaust manifold, turbine housing and HFC/downpipe are ceramic coated
Tuning:
- Custom Me7.5 tune written by ASP consisting of:
- 93octane 'low boost' file
- 93octane 'high boost' file
- 109octane 'race gas' file
- valet mode
- ignition kill
- SAI delete
Other stuff while the 2.0L was constructed:
- 2.8L 5spd manual trans
- 4:1 center diff
- 034 MotorSport Street Density motor & transmission mounts
- JHM 'solid' shifter & shifter linkage, bushings & Delrin shift knob
- custom boost gauge in rear view mirror
- 034 MotorSport B6 High-Output Fuel Pump
- SouthBend OFE SS clutch w/ OEM Dual Mass Flywheel
- drive-way motor swap
Keep in mind these particular graphs do not go up to redline (around 7400rpm for me). Reason being was there are over 500miles on the dyno to get 1) Me7.5 figured out and 2) my files written from scratch. Mark did not take my car up to redline every single time but the files are written and work well up there. I will be getting more data as time marches on as well. Next time I'm back at ASP (later this month) we'll get some full pulls. I am also going to EPL this coming Saturday with a tank of C12 fuel so I'll be sure we get some full pulls there .
I will have logs to go with these dyno pulls soon. A/F, timing advance and everything is spot on.
We explored a lot of avenues within the ECU to hone in on the files I currently have. Higher boost on my car did not necessarily mean more power (naturally, given the turbo's efficiency window). What does this all mean? There is another source for tuning and for tuning these BAT and fully built motor projects you guys have. Both B5 and B6...
Re: dyno graphs (yes, my Avant is tuned and making good, streetable power)
to think if you would have pulled the trigger on a 30 series or better we would be shitting our selves in sure. 330whp from race gas is insane, very smooth power delivery super jealous

Yup. That doesn't mean you guys can't do that
Perhaps another vehicle or another life of this vehicle. In the meantime I'll enjoy what I currently have.

Good to see you all set up and running! Congrats Doug.

Re: dyno graphs (yes, my Avant is tuned and making good, streetable power)
Congrats. I'm glad to see it up and running.
Considering the numbers and setup, it looks pretty stout.
I don't see any water/meth inj, is that a future thing, or you just don't want to?
... You're up to modded E46 M3 numbers, go find one and make it your bitch.

My car on 93 octane and meth made 301whp 300wtq with my stock 1.8 liter engine and gtrs turbo. I raced two M3s with it like that and was side by side up to around 120mph when both M3s then let off.

They should have a weight advantage, and better gearing.
I just want to stop M3 people from laughing at me at the track. (inside I'm laughing b/c they spent too much money)
Re: dyno graphs (yes, my Avant is tuned and making good, streetable power)
Been driving the Jeep around. Its uncomfortable.
No meth injection. Not on my plan. As much as I fully understand the concept something just scares me about injecting a water mix into my engine after the money I have spent on building it...
The numbers are what they are. You guys should know better that this is one set from one particular dyno. Things will fluctuate and absolute values of the peak numbers will differ. You'll see once I get some data from EPL's dyno this coming weekend. Besides, I'm concerned with the area under the curve and how the car drives on the street.
Here's my charts overlaid with a bone stock B6 A4 1.8TQM that was dynoed only a few days earlier than my charts. Granted its not the same day, same exact conditions, but you get the overall idea.
93octane -vs stock (dotted)
109octane -vs- stock (dotted)
I've gotta go tend to a huge box from ER that arrived today. Enjoy!
Re: dyno graphs (yes, my Avant is tuned and making good, streetable power)
Nice charts Doug! Looks like your car can actually make nice power down low around 3,000-3,500, as opposed to many that don't begin until 4,000+. Yay for the 2.0!
I totally agree that the car being streetable is much more important than peak power. Area under the curve > height of the curve. Nothing is worse than a dyno queen.
Congrats on getting the avant back! I'll be in CT soon, possibly on the 13-14 of Dec. I DEFINITELY need a ride!
Did Mark have any input on the effects of the HFC on power? Im very curious considering I'll be running one as well.
