Drivetrain RMW Tuned after AMVIV
This graph shows where I started with the following bolt ons and no tune:
17%, CAI, DFIC, Invidia Exhaust, 380's
With Jan's tune and the addition of:
RMW Head, RMW Header, RMW Cam, RMW Quiet Catback, 440's got me to where you see!
Holy crap I have to tell you guys..... the car is amazing and I can't believe its snowing in Utah.... I'd be out enjoying it constantly but its hard enough to keep the tires from spinning on dry pavement let alone on snow!

What does this matter for?? I am sure that 99% of the readers of the thread know Jan didn't install all those parts and then tune the car in the same day. Is this just another attempt to start a posting war on here?
A: Before the installation of all the parts, so a baseline
B: or was with all the parts already installed but NOT Tuned
The parts were not installed by Jan on this tune day. I installed them and drove the car to him. The previous number was from my first tune with just bolt ons. The dyno chart I posted shows where I came from with bolt ons without tune, and where I am now with tune and the mods in my sig.
My first tune brought me from 183hp and 158trq to 211hp and 183trq with just the bolt ons I listed on my initial post
17%, CAI, DFIC, Invidia Exhaust, 380's
With Head, Cam, Header, Exhaust and 440's it brought me from 211hp and 183trq to 252hp and 198trq

Wolf is correct!

Anyways, impressive numbers, glad to see another High HP SC rolling around...you are going back and forth however, are you claiming these numbers at the wheels or at the hub?
Thank you, that was I was trying to understand... wasnt trying to prove anything, just understand. Please dont judge me because of how other jump my threads, I dont do the same Anyways, impressive numbers, glad to see another High HP SC rolling around...

Enlighten me pleaseJan tunes on a Dynapac, they measure at the hubs
Ummm, okay... well under your sig in your alliance it says 252whp... hence my question. I had figured that the dynapac measured at the hub, thats why I asked, didnt know if you had figured the calculation to get that number to the wheels...

Longboard
When I say hub horsepower it doesn't sound the same as wheel horsepower. WHP or HHP, I guess so I choose to call it wheel horsepower! But ya, the 252 was at the hubs on a dynapac, sorry for the confusion
By "wasnt trying to prove anything" I think I was getting called out because u guys thought I was giving you problems about Jan not being the one who installed the parts... My real question was when the parts were installed in relation to the 'before' dyno. Tricky how things are twisted up. Thank you for the clarification Intense, I have never put my car on a dynapac however am curious now to find out what the differences are... hopefully this will help us ALL understand why we have these unnecessary debates over dynos and numbers.

intense- Those are some crazy numbers when I think of all the mods I have on my car including Jan's tune. Not considering the minor upgrades and suspension mods, The major difference between my 220 whp and your 252 whp are the RMW parts in head, cam, catback-header and larger injectors.
I would do it all over again for those extra 32 whp if I had the money to change the parts.

(waiting on the local dynapac to open up)I'm not calling you out. Most know what camp you're in. Your even a moderator on the Mynes web site so it's pretty clear you do have an agenda. If you do put your car on a dynopac it's only for one reason and one reason only
. To stir the pot.Longboard
i think stirring is good....up to a point, and then it's not.
as a complete outsider, i'm just glad jan and mynes still care about the r53. i think a little competition is good and will probably bring out the best in both and benefit the r53 motorhead. i now have rmw and mynes parts
Dynos...
really, there's more to HP readings than just the type of dyno. The "extra" power of the hub measurement is because the torque doesn't have to accelerate the wheels and tires. The amount of energy it takes per unit time to do this depends on the RPM ramp rate that the measurement was made over. The lower the ramp rate, the less the mass of the wheels effects the measurement.
With tire and wheel on a roller system you never get rid of the deformation energy of the tire, so that will take a bit of work to overcome no matter how slow the RPM ramp rate.
Even the best of engine dynos are a 1% measurment. Single runs on dynos in less controlled environments are even worse. Just take the numbers plus or minus 3%-5%, drop everything past the decimal place, and call it a day. It's not a pissssing contest over the absolute number, it's about the percentage increase over an RPM band that really matters. Other than that, take it to a track and either run a 1/4 mile or watch what happens to your lap times.

You guys are worse than the BMW guys. I swear. Hey Sush....I need to do my K-Sports on the BMW on the DL tomorrow. I just need to use your place and tools. You dont need to help. I went by Johnny's to drop off the front end but he was gone....
. Im going to a movie at 6 or so...so give me a ring later.

Well, were still waiting to get the others dyno sheets scanned so I'll give you what I can remember
2003 MCS
RMW Header, CAI, Magnaflow, 15% pully
Went from 149hp and 153trq to 207hp and 185trq!
His cat was plugged on his stock header! Added the RMW and BAM! Ask him how his ride home was eh? He didn't even recognize his car!
2003 MCS
Webb head, Webb cam, Webb CAI, Milteck header, Milteck cat back, 380's, GRS intercooler, 17%
Made 224hp and 185trq (Sorry, cant remember the starting numbers)
One more car and I can't remember the numbers, Made about 207 or 211 hp. I'll post the sheets when I get them from these guys. Everyone had some big effin grins on the way home!
