maybe its cuz he doesnt have em' or he doesnt want to kill the interest
regardless, i still want see and hear this...

 

OK, then which is the accurate one? And why do different synod do this? If I tell someone my car dynos at 320 and tests it on his andit say 170...there's going to be problems.

 

They're basically all accurate. You just can't compare across dynos. It's sorta like using different scales to weigh yourself and getting different numbers. The correct way to use a dyno is to use the same one (same machine/location, same operator, and hopefully under the same conditions if possible) to measure your car's power before and after your mods to see if you had any gains or losses. If you start with say a Dynojet for example that normally reads pretty high and get some baseline numbers and then add some mods and jump to a different shop that uses a Dyno Dynamics, you'll probably see low numbers but that doesn't mean your mods lost power.

Here's a good write up on dynamometer testing by Steve Dinan: http://www.dinancars.com/bmw/technial-info...dern-bmw-engine

 

Chances are if we have to ask we can't afford it

 

I the compression is really high on these cars. Its going to take lots of tricky tuning and meth injection and filling up with 110 just to keep the heads attached. I have been down the road of high compression supercharged motors before.

 

The SC is in development so no pricing info is available.

 

Correct

Dynos when used correctly are designed to compare delta gains under identical conditions. The actual HP figure means very little as dynos and dyno testing methods vary greatly. What you want to look at is how much power was gained and was the testing conditions the same for both. This test was done on the same day , same temp, running the same fuel. This car was down about 20 hp from its factory rating mostly due to the fact that it was almost 100 deg when we tested it. If we were to run this test in colder weather say 70 deg the car would make another 20 hp on both the baseline and software tuned runs but the delta gains would remain the same.

Also the whp number you see in blue is uncorrected. With correction it would be about 260-270 whp.

 

Roman, any roughish eta on when it would go into production?

 

Early next year

 

Slightly off topic but is the SC for the M5 still slated for Dec?
