I like how darren put in the "Double D" in the video

The dyno numbers have not been fair for the stroker motors because of the limited air flow.

I'm glad they ran afterwards because this shows that a dyno is only a good reference for one car itself as oppose to comparing two cars.



The Classic BMW dyno here is a huge ego crusher. I currently am dynoing there for the sole purpose of keeping a controlled device for measuring mods. My car only dynoed 438rwhp will full bolt ons on the Classic BMW dyno but I believe in a dedicated dyno room I could see numbers at least at 480 on a dynojet.

I think this adds credibility to the argument that dyno's can be very misleading. I still think verified 60-130 times rule, fwiw.

Nice win Darren!

The debate around dyno numbers are giving me more of a headache each day. Ultimately though, it's just nice to see what happens on the road where it matters.

like m5ranger, i too am confused... i understand that proper airflow for the dinan stroker will provide more power, but how come the numbers are so much lower than what had been documented with simple bolt-ons like rabdog's RPI setup? darren... did you guys not have a fan that could give 50mph+ airflow?
again i know numbers don't necessarily translate to real world results but they do give a relative performance picture.
the next obvious question is how much difference is there between RPI bolt-on's vs dinan stroker on the dyno in identical conditions? i recall watching kenny stare down darren's brake lights in a very dark video?

Not only did Kenny stare at his brake lights, he got walked pretty hard and it would have been the same result with RabDog's car. The point is...

Obviously the dyno tells only a small piece of the story. If you go by dyno performance here, same hp, same weight, 100+ lb. more tq to the Caddy, then Darren should have been anihilated. But it wasn't even close. It was an immediate run, not walk, away from the Caddy and once again the 997TT.

Great job, D! Way to rep for the stroker crew. I think Fubar might want a rematch in his other blown domestic vehicle. The outcome might be a little different! lol
