Diamond Aircraft

Supercharger for Diamond Aircraft

This modification makes the DA-40 a different aircraft with new speed and altitude performance.

(This plane was an honest 140 knot plane before being supercharged)

New data from 7/24/11

New max continuous TAS is 164 at 8,500

Other MAX airspeeds

    12,400' 161 TAS, 24.00"/2680 RPM
    11,485' 162 TAS, 24.78"/2680 RPM
    10,500' 161 TAS, 25.73"/2680 RPM
    09,470' 162 TAS, 26.70"/2680 RPM
    08,486' 164 TAS, 27.61"/2680 RPM
    07,473' 164 TAS, 28.75"/2680 RPM
   
New max climb average climb rate from 306 to 12,12,545 is 770 FPM
Max all out climb from 9,600 to 10,600 was 1000 FPM.
Max all out climb from 9,600 to 12,500 was 773 FPM.

Here are a some cruise speeds:

At 8500' we've seen 157 KTAS on 12.7 GPH and 2450 RPM. IAS is 5-6 knots into the yellow arc.
At 8500' and 2450 RPM, 150 KTAS on 9.8 GPH.
At 10600’, 155 KTAS at 2400 and 12.0 GPH.
At 12500' and 2300 RPM, 150 KTAS on 9.5 GPH.

Excellent LOP operation.

Eighteen pounds installed.

6 year/ 1800 hours warranty.

From the forums:
Flying back from Lake Tahoe today (a sublimely beautiful place for an airport and benign weather for a change), I flew for a few minutes at FL 165. I was on oxygen of course. The aircraft performed very well with TAS gradually increasing to 130 knots, around 97 TAS, 16.2" MP and 2200 rpm. 6.8 gph.
The Density Altitude was 18,266 feet.



Tim, thanks for sharing this info above. I was needing something to compare the supercharged plane with. On my recent flight from KAPA to KDRO I had the following #'s.
IA: 16,500
Alt: 30.09
DA 18,756 (seems cirrusreports does not show this)
MP: 20.2
GPH: 7.9
IA: 117
TAS: 156
I'll post more on the dedicated thread.
