Bone stock I dynoed 273whp - with roughly a 15% correction factor that's 313 hp at the crank... that's pretty accurate to the factory claimed numbers. BMW is also known to underrate some of their engines, such as the n54-n55 and M models.

Again, dynojet are not true numbers so your 273 plus 15% correction is an exaggerated number. That is not what you make to the wheels given the weight of your vehicle and resistance it adds. You make 300 at the crank on real numbers, period. Don't try and act like dynojets are precisely accurate. They are used by companies to advertise products as to show the highest hp gains, not the most realistic. If you want to try and "out dyno" somebody then dynojet is for you. But if you care about real numbers, then look somewhere else.

You roasted him fam. These cars accurately make about 240ish I think or thereabouts bone stock to the wheels. On a mustang I think with FBO minus the turbo the N55 for the F30 made about 275whp

Dynos are used as a tool. I don't understand how dynojets are not accurate. The same correction factor is used on all dynojets... so if I go to a local dynojet, run the car, get the numbers... then drive down a couple states away to another dynojet... utilizing the same correction factor and smoothing, the numbers will be similar. So if you get a baseline and make 200 whp... add mods and make 250whp, you have gained 50whp. So how is that not an accurate representation of mods? Do they read higher then mustangs? possibly? are they Inaccurate? sorry bud you are wrong.

I simply stated you can do a baseline dyno on a dynojet (zomg even if the number reads higher) and then dyno after whatever mods you added and get another number... then look at the difference (hopefully in the positive) and you will be able to see your gains.

Keep thinking you know it all bud.

As stated in my very first post, they might give deltas but do not state true start or finish numbers. My point was, they don't tell you what actual numbers you are putting down. They will be the same across all dynojets, yes, and they will give you a delta, yes. But with a dyno jet, your starting and ending points are both higher than the actual numbers. While deltas will remain, it does not help for testing thresholds. Therefore you don't know how close you are to ruining your transmission or blowing a piston.

GT, what the hell are you blaberring about honestly? LOL dynojets "might give deltas". What thresholds can you know off of a non Dynojet dyno when they all vary so wildly out there? You're not making much sense TBH.

My point was, it's helpful to know the numbers that are hitting the ground from your car to see if you need to enhance any mechanical weaknesses in your car before adding more power through your engine. Might have gotten a little carried away

Yall arguing over dyno numbers is like arguing about whos penis is bigger but none of you know how to use it. Meaning wtf does it matter how much power you made if you run slow at the track. This is why my truck never touched a dyno but still broke the 1/4 mile records.

[mookie45]

So are there any 1/4 mile times or 60-100 mph pulls?

This is the only type of dyno I use

I apologize for that, just curious to know differences between two dynos. Have heard dynojets read higher than mustangs, and wanted to see if there were any other data points for comparison in order to back up that claim. Now back to breaking some world records

[f30_garcia]

well ordered my port injection today so I will be trying lol

[FSociety]

J_MENIS props for that, i do the same way
x4 BM3 STG2 93vs 335/rwd/6mt/DP/Jb4 map2/5/7

Here I run from 30 roll against F80 M3 ZCP stock, then other runs multiple times against 335GT DP + Activeautowerke active-8 on map7, and F15 X5 35i dmetuning backend flash jb4 with 2 gals of e85 (All friends of mine, we just compare for data)

sicmadek cant wait for strips to open here

Meth for cooling, PI for Fueling ? Looking forward to another WR lol

[mookie45]

This is getting good!

What is that "dyno" good for? Even worse for deltas than an actual dyno hahaha!

What good is deltas? A dyno is a tuning tool. It will not tell you how fast you are.

Nice runs Robs. Always taking advantage of those 6sp manual bad driver out there.jk

Great runs. Thing scoots..

My boost is very identical to yours and the way it tapers. Good stuff.

First video was late December/Jan i think, running my 93 map
Second video was running a little more aggressive NEW map that i should run with E30, but was running on 93 that night. (I'm expecting better results when I add E30 mix) the runs were planned last minute and unfortunately no time to add E85.
More coming soon

BM3 switch for me tomorrow. Will post more videos when I get the chance
