Dyno Shootout: Battle between Dinan and RD Sport for 4.6 Liter Stroker Motor Braggin

This graph shows all three cars on the same graphs compared to each other so you can compare the tunes, afr's, etc.

[Malek@MRF]

What's the definitive answer here as to why these TWO stroker cars from two different companies are making lackluster performance?

Aleks what is your take on this? I went through a lot of your data and scrutinized it (great job logging everything!) From what I can tell is that these stroked and bored motors could possibly benefit from a better tune, especially the Dinan car as both the Dinan and RD car are running rich with conservative ignition timing. Are they limiting the timing to possibly protect the motor because of how much thinner they made the cylinder bores?

For what it's worth my M3 made 404 RWHP with the MRF Velaforza and custom NA tune with no other mods.

Looking forward to your thoughts.

Yea but for the money it wont be worth it since my car already pulls like an animal.I already have problems hooking and putting the power down,traction control doesn't even control this devil anymore.

Yes, the GTS makes marginally more peak horsepower, but the Dinan stroker makes 20-30 WHP more than the GTS everywhere from 3500-6500 RPM. That is a pretty significant advantage, even if the Dinan has some software issues hampering the results.

Good points. Duly noted.

We present the data, you draw the conclusions. That's the way we like to do it; no spin, no trolls. I can see it might be beneficial to add a graph comparing HP/TQ on a per-RPM basis. I'll do that later today.

These strokers are only 15% larger displacement than stock, so you wouldn't expect them to make more than 15% more power.

The Dinan stroker gained 6% more horsepower and 15% more torque. Torque gain is exactly where it should be, but horsepower isn't. That could be the tuning.

The RD stroker gained 15% more horsepower and 30% more torque. The horsepower gain is exactly where it should be, and the torque is clearly the superstar here.

It will be exciting to see what both of these cars can do on a rematch after they both get re-tuned with the latest software.

That's absolutely insane

Dave, stop trying to stick up for Benvo, it needs a damn tune!

LOL, Mike doesn't need anyone to stick up for him hes a big boy. I heard this before I even knew Mike. I just remember it was an issue of the Shcrick cams, but I was in a 997S at the time and not even into E9X M3s. Whether it was factual or not is another issue.

I wish PG wasn't banned so he can come on here and set the record straight.

BTW, hows the little one..not so little anymore I bet.

Can't believe my oldest is starting 7th grade next year.

NA power is expensive. I'll take FI -- twice the gain for half the price. It is great that a twinscrew kit and a twin turbo kit are in development to offer alternatives to the several centrifugal kits that have been out for a while and are now well proven.

All of this high tech testing wasn't needed to come to this conclusion.-------look here-------> http://www.m3post.com/forums/showthread.php?t=561503 ..............Phil

Dave, I was just kidding with you!

The family is great brother, two boys now, 8 and 5, I'm a very very proud DAD! Hope all is well with you!

Its pretty retarded,it hits 200mph so easy,i usually hit 200 going home every night too.It needs a little more power cause it's becoming borring
I'm thinking about doing some more work to the motor,some ideas are on the table right now and i might pull the trigger any min

Are you sure about that math?

I'm calculating a 2.6% increase in HP and a 16% torque increase for the RD.

The Dinan lost hp <1%, and only gained about 9% torque.

In this comparison, at least. Assuming you're talking peak numbers.

Amazing! Love threads like this. I really would have loved to have been there to see these two in action. I can't wait to see the film if you release it, it would be great to see them in a video.

Alekshop, amazing attention to detail in comparing these three

You should just put a jet engine in that damn thing. I heard you can keep your K&N filter if you made the swap too which is an added benefit. We all know thats where the majority of the horsepower resides anyway. Excited to see what you have planned.

You def need to get a ride in the BluDvl to understand

K&N FTW Bro
Great R&D and never let me down,LMAO
