I went to Gruppe-S today, and had some interesting results, i put down a couple different numbers. when the car was warmed up i put a pretty high number down (twice), and had other runs after idling on the dyno and a number of pulls that was low-mid sixtys. Mods are Helix DP, Apex-I catback, and Paul from SRM ecutek. btw, i put down 285 on SRM's Dynapack.

Here is my Dyno from SRM

NOTES: In conclusion Gruppe-s reads between 5-20whp lower depending on the run, than SRM on some occasions and in one run about 8whp. Also interesting in how in my higher HP dyno my Tq dropped and the lower HP dyno my Tq was a bit higher :? either way it could be conditions that determined this but these were the numbers i averaged from the pulls i got at gruppe-s...

Nice comparison.

Your torque curve on the first chart is great.

Remember to look at your curves when you are comparing, more than peak numbers. Your second charts show losses everywhere compared to the first chart.

Gruppe-s dyno gets very stuffy and hot after a couple runs or idling on the dyno, that is probably the big reason why your numbers dropped.

Welcome to the heartbreaker dyno. :wink:

Is your car an 05? I forgot. Also, what trq did you do on the SRM dynapack dyno?
