This is why you NEED a baseline - very "low" reading dynojet
This is just an example of why you need a baseline on whatever dyno you go to. I recently switched to a dynojet that is much closer to my house and I needed some kind of a baseline... So I got a stock 335xi to come by and do some pulls. These numbers are the same type of thing you'd see at a Dyno Dynamics or Mustang dyno. This is definitely the lowest reading dynojet I've seen.
It was 70° for these stock pulls: Last edited by jpsimon; 10-26-2009 at 09:35 AM.. |

Meth is the goodness. If a regular 335i dynos on a dynojet around 270-275, wouldn't that be about right where your friend dynoed for his xi considering the awd loss? What did you dyno base on the other dyno?

Could not agree more. All the "look how much horsepower I made" threads with no baseline kind of make me chuckle.... Dynos are nothing more than a tool to measure % differences - not total output.

What did you dyno stock with your xi on that dyno you did 398 on?
edit: Nevermind I just looked at your dyno sheet, very nice.

JPSimon, finally someone sees the light. The baseline is the only thing that tells you anything about your final numbers. If JP dynos at 395 rwhp on one dyno and 370 on another then is his car magically making less hp? The bottom line is a lot of dynojet's are miscalibrated to show bloated numbers because they don't want their customers to leave unhappy. If you look at delta or gains, then the top number becomes irrelevant.

I definitely agree JP!
I've said it over and over again but people still like to categorize all dynojets being the same.

I was just thinking about something.
Is it possible that this dynojet could have an option of putting a load on the drum?

There is HUGE variance between our local DynoJets. A DynoJet is not always a DynoJet.

I suppose in a perfect world you should dyno your car on this new dyno in stock form. That's the only true way to judge how far you've come.
At least you took the closest route you could by getting a stock dyno from the same model car. Good luck with Meth! |

in a perfect world I would love to dyno my car on this dyno stock, but at this point that is nearly impossible... especially with one of my stock downpipes cut in half and my stock exhaust gone

not trying to start anything but...you only dynoed one car. And tru, it would be no point for u trying to get a whole bunch of stock cars. But just dynoing one car and then coming up with.."that dyno is super low reading" if anything I'd say the car was weak.

So no, it wasn't just one weak stock car. Last edited by jpsimon; 10-26-2009 at 08:42 PM.. |
