Dyno Results and Video

These two runs were done on a Four Wheel Dyno Dynamics Dynometer.

The car is a TT Cab, which is about 300 pounds heavier than a coupe.

The HP # came in at 324.5, this was disapointing to say the least.


Here is the Dyno Chart



As you can see in the video the car had great traction and did not move around.

Do a "right click > save as"

VIDEO of Dyno Run

Most of the dyno charts we have seen were from a Mustang dyno. A stock car dynos at around 350 HP on a Mustang Dyno.

Orli930 is infamous around these parts
That is a very low number even for stock. IMHO

What gear was it done in? It looks like the spoiler doesn't come up until near the end of the dyno...

At stock 415bhp, that's a 22% (1 - 324.5/415 = .218) drivetrain loss. Is that normal for a TT on a 4-wheel dyno?

It was done at Vishnu in Pleasanton.

I don't know what gear the run was done in. At what speed is the tail coming out?

Because the #s were so low I asked to see the dyno sheet of the only other TT they have done.

My car makes more HP and TQ before 6200. After 6200 the other car makes more.

Here is the chart comparing both cars:

Just in case you want to know.

Here are the AFRs of a stock motor on 91 octane:
