Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

They always disconnect front drive shaft on a awd Porsche before any pulls, because of what Chris said.

I think a better test would be a timed performance test under controlled conditions, either 0-60, or 1/4 mile.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Does anyone know of a facility that will dyno a C4S for a fee? I am installing some new mods and there is a dispute on a seperate thread about any HP that may be gained.
ICS performance. They have a 4 wheel drive Dyno jet.
very reasonable prices. Knnows your car
Stamford Conn. Exit 8 off 95
Call George (great guy) tell him Elliot sent you.

Be very careful with a AWD on a dyno, one guy with a TT fried his differential on a so called awd dyno, but I'm sure the dyno owners paid for the damage, right? Probably a g timer will give you as reliable info anyway, chassis dynos are basically bull****. A real dyno requires the engine be removed from the car.
Gcohen,
As i said ICS performance knows your car. They always disconnect front drive shaft on a awd Porsche before any pulls, because of what Chris said.
Their Dynpojet seems to be conservative in its values and you get accurate and consistant RWHP which is what counts.

I wouldn't mess with a chassis dyno. Even for an A:B comparison of mods, you may not get the answer you want. The reasons are fairly technical, but if you want to read about it, try Steve Dinan's white paper on dynos. It refers to BMW's but the same principles apply:

As one of the previous posters noted, you really would have to do an engine dyno to get good results.
I think a better test would be a timed performance test under controlled conditions, either 0-60, or 1/4 mile. Then you know whether your mods make any real world difference.
Finally, be real, real skeptical about any "dyno proven" performance mods. There are a whole lot of ways to make a mod look better than it really is.
