Drivetrain RMW Street Header Dyno

So says the unaffiliated Mini Cooper owner, who doesn't think any vendor should get involved in this thread...
I often wonder with all the vendor claims (from mmany of the vendors, not any one in specific) if they'd actually back up their claims by putting their money where their mouth is.
I.E. "Hey, our part is better and makes more power then theirs. You pay for the install, tuning, and dyno time, but if it doesn't make more, we'll refund your money on the part and the labor charges you spent giving us a shot!"
Oh wait, that's right, that'd never happen in any of the automotive circles, would it?
I guess everyone has to drink some sort of kool-aid and have a little faith and trust in the folks doing the selling, and understand that like many other areas of life, building relationships often mean more, then 1 or 2 HP ultimately.
I mean, heck, I still have my one-ball exhaust installed... honestly will I see much/any gains in switching to an aftermarket exhaust with my stock head?
Not something I'm willing to gamble on, not with my own money.
I am looking forward to your future posts regarding the new Mynes header on your car... and heck, if they wanted to stand up and tempt me to drive to Arizona and have one unit swapped for another, etc. etc. I'd be all over it. Otherwise, I'm happy with what I have now...
Cool - I'd be interested to find out which unit they use.
By the way, your signature with the stop light like Go/Stop/Turn is really cool! I like it.

Yes, your numbers will always ultimately be higher than mine (mod for mod) on that type of dyno.
Most of my gains have come from a tune.

Our modifications may not be similar.. that is what I mean by "Mod for Mod"
If our cars baseline the same and after every same modification we did on our cars gave us the same dyno numbers, we could compare "mod for mod"
Thank you Wake, that is what I meant. I also explained that one post up from you.. I was just too slow!
Understand that you have more mods and should make more power. What I'm talking about is the gap between TQ and HP... You have a much higher HP # but I have a higher TQ#. Think that a RMW tune would raise the TQ for you and close that gap!
TQ to push the HP.
Interesting idea, but HP is dependent on TQ, they are not independent variables.
Just like voltage and amperage.
High horsepower with low torque is useless. That is why if you had more torque you would have more USABLE horsepower. Glad we agree!
Hondas don't have high torque but gets high HP but they win races. Diesels makes tons of TQ yet still slower than low TQ and high HP cars. The conclusion that high TQ engines wins races does not apply in real race.
Have you been watching what the Audi Diesels have been doing on the track?
Anybody in racing will tell you that Torque wins races.....
Ask Randy at RSR weather he would rather have 10 more lbs of torque or 10 more horsepower in their Mini's in Grand Am. If he say's horsepower I'll eat a bug...

Very interesting, but this supports (albeit with one observation) what I've suspected all along--headers don't do much for a Mini. Cams do amazing things, but my headers (stock, cheap and expensive) don't ever seem to have added much. Of course, I also believe it's a package--system thing. Headers sound good, and when they glow red hot (mininuke) they look good!
Anyway, thanks for posting this very interesting data.

The old saying is "Horsepower sells cars and torque wins races".
I agree with this statement for vehicles that are meant to be race vehicles. You can't say that with a normal VW TDI or Semi-Truck, because lets face it - they are what they are (other purposes than racing heritage)
Anyways, lets not derail the thread.
I agree that I would LOVE more torque minimarks - I possibly have more than you at the wheels and in area under the curve (but we can't compare since we used different types of dynos).
I would attribute some of your torque to your small supercharger pulley as-well. I am using a stock supercharger pulley.
The Newman camshaft has given the car a pretty decently flat torque curve that is centered around the mid-range.

Not just race cars but great driving and running street cars too! Not talking about down low tractor type of torque like in a semi but good strong torque as the RPM's build and HP goes up. Honda's VTEC engines are great on the track but are tuned to make power and their torque at very high RPM's, that's why if you step on the gas in mid range RPM's in them not much happens. When Jan tuned mine he first had it getting more HP but the torque wasn't as good so he actually backed of a little of the peak HP and got more torque with a much wider powerband! Now the little motor just keeps on pulling!

With the camshaft, the car feels quite stout compared to the stock camshaft.
I guess you didn't see the TDI cup on speed... The racing was great and all the drivers talked how awesome the TQ was from the TDI on the track.Mini has a turbo deseil coming to the US soon that with a few treeks could be an awsome choice for the track.
Longboard
While in Germany, my rental car was the 2 liter TDi Volkswagen compact van. Basically a lifted up Golf. Power delivery was great - lacking in horsepower yes, but a very spirited driving experience. It suffered a little puke and die turbo top end, but the bottom end came on very nicely.
The new Turbo Diesels have came a long way since the 80's even. Heck, I've seen Cummins powered Rams tearing up dragstrips.

Anybody who belives any kind of a aftermarket header vs a stock unit will make the same or less power is a freaking idiot. I and many others have this header. We can show dyno graphs and just say by experience that this header is one of the best power making once made. I can't tell you why your numbers are the way they are, however, you should talk to your dyno guy and see if he did not have to do anything with your numbers being off.

If you do I would be interested in seeing it
Just did a quick search and this is the first thing I found. Dyno+tune vs obx and rmv on a automatic car. Not the best example but you get an idea. The obx has been proven to be better then stock so this shows how much better the RMW is vs the OBX. I am sure there is way more data, but do we really need prove of this ?

"DYNO GUY" sounds like superhero to me.
