More specifically JB4/dp/intake map 2. I am ordering the Jb3-4 upgrade/intake/downpipe and would like to know roughly what my numbers would be, if anyone has one or has seen one please post it up.

Thanks!

[klov335]

Would like to know also

Long time ago, 304.2 HP / 355.5 FtLb on a DynoDynamics, 93 octane. Think that might have been Map 1, but that was with an intake, AR hi-flo catted DP, JB4 stg 2.

[SCSRe92]

damn 304hp is all you get out of those 3 mods? how much to the crank?

[CombatNinja]

That would be equivalent to 350-360 crank depending on dyno, calibration, etc.

N55 drivers must accept the fact that these cars will be showing lower numbers than the N54s due to limitations related to the single turbo. I think 375ish crank will be the upper limit on a stock turbo. I know some tuners claim more but I am skeptical.

I put down this much with just jb3 stage 1 beta tune on a dynojet, was that dyno reading super low or what?

Meh.. That dyno must be reading super low or he was on stock map.

Here is me putting down almost identical numbers with the n55 beta tune:

300/314 on a mustang dyno.

Wrong.....everyone on this board needs to accept the fact......that

Dyno numbers dont mean shit.

Take it to the track.

[CombatNinja]

Dynos vary, operators vary, weather varies...There are too many variables to really say the cars make "X horsepowers". All I know is that trap speeds in the quarter miles are a pretty damn good indication of power levels and these bolt-on N55s are basically making anywhere from 360 to 380 crank horsepower. There are a few outliers as with any platform but those are typical figures. Similarly, typical N54s are closer to 400 crank when looking at trap speeds. Trap speeds don't lie.

Wrong... Dyno numbers show how much power you make, they won't show you how fast your car is.

If two competing tuners have baseline + tune dynos that definitely means something aka which one has more gains.

Yeah, and the "track" shows that N55s make lower numbers than N54s. So thanks for proving my point.

[pwdrtoastman]

FYSA, dyno dynamics typically read lower than MD. A perfect example my evo ix on a mustang dyno put down 488/455 the same set-up with weather on a dyno dynamics put down 450/415

[F335i]

On map 2 340rw to 350rw, I don't know about torque but it's always higher than RW.

[SCSRe92]

how much will these mods make on a n54 vs a n55? and the dyno shows you how much you make on paper, it doesnt add variables such as weight, conditions etc.

[geared]

while that may be true, the n55 has not been out long enough for anyone to take full advantage of it.....what were n54's putting down/running a year after they came out versus now? That being said, there is no doubt that the n54 is a stronger car.

Your first comment is accurate, noone's arguing that.

However, your second comment is wrong and why I made my statement to began with.....People that compare different dynos in different conditions are simply dumb....no other way to put it. Unless both are on the same dyno with the exact same calibrations with the exact same conditions you can compare....which is so unlikely its not even funny....play the lotto - you have a better chance!

A dyno is good for comparing your OWN progress - and even using the same dyno can give you misleading results because of the hundreds of variables at play with air temp, motor temp, humidity, gas, etc

I'll say what I said before....take it to the track...comparing dyno numbers that others achieved on a different dyno is a waste of time, in my opinion.

[geared]

I think 375ish crank will be the upper limit on a stock turbo. I know some tuners claim more but I am skeptical.

FWIW.....I plan to put down close to 360-375 rwhp on a dyno jet with my mods once I get my e-85 mix on point.

n55 6 spd
jb4 map 5 ISO
ar 4 inch kittenless
AA Intercooler
CPE CP
BMS OCC
BMS Intake
Dinan Exhaust
Flex Fuel Wires
e30ish / 93

For sure well more than 375 crank.

[geared]

it doesnt add variables such as weight, conditions etc.

really old shitty dynos maybe.....but yes it does....your car is adjusting for conditions as is the dyno (hence my comment that comparing is futile).....SAE vs STD......and plus a weight is entered in

[geared]

There are two ways to look at accuracy: accuracy of the dyno itself, and the effects of introducing other variables outside the measurement system that can affect what the car is actually doing. As long as the dyno is properly used and calibrated, then all dynos are accurate for the conditions. The pitfall is trying to compare results across different platforms.

......

To the extent possible, you want to run multiple tests within a consistent shop environment, including similar ambient temperature and pressure. The more rigorous the setup, the more exacting the dyno calibration (on those load-sensitive dynos relying on brakes and absorbers), and the more controlled the overall shop environment, then the more repeatable the results, and the more suitable the facility is for measuring the effect of small incremental changes. Still, once you get down in the 5 percent range on the average chassis dyno in the average facility, it is difficult to evaluate whether the change is real or due to environmental transients.

There's nothing to read and you completely derailed this thread to prove a point that no one cares about. You should consider writing a book.

I asked if anyone has or has seen a dyno of an n55 with tune/intake/downpipe. What I plan to do with that information is for my personal use and I don't need you telling me its pointless or what I should be looking at instead.

Your intentions may have been good but you come off sounding like an ass hat.

[Suds]

Sounds like you two are having an east coast / gulf coast dispute.
You boys need to settle this!

DynoDynamics always read really low, they call them the heartbreakers. The guys at the shop told me they typically read 12-15% lower than a dynojet, so that would be equivalent to approximately 355/410. But the only real way to tell how much of a gain you'll get is to compare vs runs on the same dyno with and without the modifications.

+1 haha

I'm also interested in seeing this. No need to get into minutiae of dynos.
