Hi All,
We had the opportunity to spend some considerable time dialing in an E85 tune for NASA Time Trials TTD class. With a lot of fine tuning on this car we were able to hit 200 wheel horsepower on a DynoJet Dyno.
Vehicle: 2013 Scion FRS
Engine Management: Delicious Tuning EcuTeK ProECU
Exhaust System: Over Pipe and Straight Pipe Axel Back
Headers: Stock
Intake: K&N Panel Filter
Fuel E85
HP: 200+ dynojet (175whp dyno dynamics)
Vehicle: 2013 Scion FRS
Engine Management: Stock
Exhaust System: Stock
Headers: Stock
Intake: Stock
Fuel: 91 Octane
HP: 160 dynojet ( 140whp dyno dynamics)
Not only are you not going to believe it, but even the racers competing NASA Time Trials did not believe it, especially after it just broke the track record in TTD class. Previous record held by a well modified Mazda Miata was 1.53.066 and it is not held by a 2013 Scion FRS with a time of 1.52:741.
For comparison between Dyno Dynamics Dyno and DynJet Dyno's
Stock 2013 Scion FRS produces about
- 140-150 whp on a Dyno Dynamics Dyno
- 170-180 hp on a DynoJet Dyno
- 15% difference in the worst case (150 * 1.15 = 172.50 hp)
E85 2013 Scion FRS produces about
- 175 whp on a Dyno Dynamics Dyno
- 200+ hp on a DynoJet Dyno
- 15% difference in the worst case ( 175 * 1.15 = 201.25 hp)
As another verification (besides the track record) we have the option to display the dyno chart in "Comparison Mode" which compares the horsepower to a DynoJet Dyno. In "Comparison Mode" we are able surpass the 200 whp mark by quite a margin as seen in the [U]*first image above[/U].
So yes you can make 200+ whp on stock headers with minimal mods. Next test is to see if we can do it with just a panel filter. Spending a LOT of time playing around with Intake and Exhaust overlap along with a few custom maps in the RaceROM custom mapping in with EcuTeK ProECU has allowed us to tweak out every little horsepower from the engine while being reliable and consistent even on the track.
Finally we are bringing the vehicle to a DynoJet in the coming weeks for the final verification as everyone I am sure would like to see.
Cheers,
