My Dynojet Results - modded e36 M3

[jworms]

to be honest, my results were somewhat bittersweet. recently i was 'called out' about my dyno numbers in my sig. i have explained over and over again that the 270rwtq and 271rwhp in my sig are from a dynapack which does read higher mostly because the measurements are taken at the wheel hub, without the drivetrain loss of the wheels/tires. so i went to the same place i got my stock dyno done at and did some base runs on their dynojet with my current setup. here's the best run i got:

first, here is my current modlist:
M50 Intake Manifold
Conforti 3.5" CAI
AA Software
3.5" HFM (unplugged)
Fan Delete
Strömung Exhaust
UUC Stg2 Ltw Flywheel w/ Stg1 Clutch
AA Track Pipe

...and the graph:


and here's my stock graph overlayed with this one:



now before all you nay-sayers jump the gun and reply with, "you didn't make 250rwhp like you said you would." i also asked the same question after receiving my results. first, let me say this: i've never been one to exaggerate facts and this experience won't change that. everything i post in this thread is factual and not 'fudged' at all. though, i expect most of the people who want to see me fail will stop reading here and that's fine, but i feel obligated to present what i found:

the owner of the shop mentioned to me (when i was making the appointment, before i actually went there) that his dynojet produces lower results than other dynojets. now i didn't think much of this at first because my stock dyno produced 208rwhp and 210.8rwtq which is right on target for a stock s52. i thought the guy was just trying to make customers feel better about their numbers or something which i don't really care about. what i found out is that he might have been telling the truth...

you might hear people say that dyno results from different dynos are not comparable to each other - anyone with a tuning background will tell you this. if you don't believe that then just look at my dynapack results compared to my dynojet ones. the same thing goes for results from the same type of dyno - you really can't compare them. so, with my results still lingering in my head i wondered what others have got from this dyno. as a comparison i asked the owner of the shop if he had any e36 M3s to compare to...he didn't (OT: they used to have a lot more dyno run files available but their computer crashed which caused a lot of data to be lost. i had to bring my own base line dyno files beacuse they didn't have them), but he did have a stock 2000 m roadster (same s52 engine as me). here's what that thing pulled on its best run:


ok, that's odd i thought. that's significantly less than what my car produced for its stock baseline dyno, but that is only one example to compare to so we went searching for others. we found a 335 with Borla catback exhaust recorded on the same dyno. here's its best run:


hmmm...interesting. those things typically dyno a bit more than that stock - generally around 27X/28Xrwhp and similar rwtq from what i've seen - and this one even has a catback exhaust system on it. strange...maybe this dyno really does read a bit lower than other dynojets and my baseline was just a testament of its freakish nature...maybe not

so in conclusion you can take what you want from this thread. i'm sure i'll get flack for the numbers not being 250+ but that's fine, like i said i expect that and would be disappointed if it didn't happen

for anyone who is interested i got the owner to give me the dynojet files for all of the runs depicted above. you can download the dynojet software to view them from here: http://www.dynojet.com/downloads/software.aspx

if anyone would like to see how their car stacks up at this dyno (and live in socal) the website/address is located here: http://www.rddyno.com/. the owner is a cool guy, his name is steve. i am obviously very interested in the results others with similar setups, or even stock setups get at this shop.


this thread is, of course, dedicated to all my fans. thank you all, for without you this thread would have never existed

Nice

[Bimmerforums]

Great numbers and are right in line with my numbers. I have 5rwhp less and 10rwtq less than you, but you've got software and exhaust.

Must be fun to drive

Edit: Mine was off a Dynojet as well.

[Eric98Sedan]

Oh you didn't hear that the M50 manifold is no good?

[Mr. M3]

Go ahead and throw some cams on there and you will be set . Nice numbers.

[GG///M3]

nice numbers.

[Scotth]

What is wrong with your A/F ratio's? Pretty erratic?

[MRMARSH]

still with the hfm unplugged? oh my...

running with no MAF has that effect there's definitely some power to be had on my car with proper tuning.

here's some pictures from the session:
getting the car setup. yes i know it's filthy.


92,897 miles and still running strong!


MAF unplugged


gotta represent

right on target, my previous M3 with your same mods minus the 3.5HFM and the track pipe.put down 237RWHP and 227TQ SO my guess is with the 3.5HFM and SW would have same results.
Now you can change your sig to read 242RWHP 232TQ

What is your making now?

No idea, last dyno with only 6PSi was 297RWHP & 260RWTQ. I have an appoinment next Tuesday to re dyno my car, now is at 9PSI with WI, M50 intake manifold and NickG tunning; I'm changing my set up to RMS stage II (within 2 weeks or so) 13PSI With NickG tunning I should be putting down 400RWHP ...I hope.

[MRMARSH]

plug that thing in already! lol jk dont wana kill ur thread...as long as ur happy with it thats all that matters!

[Serious]

all im going to say is that those are fantastic numbers for your mods.

i knew your car made a ton of HP and with headers/pullies you may hit 250whp, but 250 rwtq is just way too much for an s52.

Looks like u owe me a beer

i still believe that i could hit at least 250rwhp and 240rwtq on a different dynojet, but i'm not gonna spend the time/money on it right now. for the sake of what this thread dictates, i definitely owe you a beer

[bennyfizzle]

first of all, the hfm unplugged seems retarded, i don't understand that.


second of all, if you're going to have it unplugged why not delete it altogether?

[FreewheelBurner]

At first i was gonna say nice torque curve on your engine, then saw the 335's

hes right if you arent going to runn the hfm, get the sensor out of it, its just inthe way and useless.

[Balthazarr]

How the blazes do you get 240rwhp with that set of mods?
Is the track pipe that beneficial?
Lastly, what did you do to get the engine/DME to compensate for the loss of the HFM signal?

[TAMUmpower]

Why is your HFM unplugged, is it broken. Its there for a reason.

i completely agree. i think between getting rid of the MAF altogether and deleting my traction control i can probably pull another 5rwhp out of it.

1)
2) i believe so, but it's hard to say. at the same time i installed the track pipe i also unplugged my MAF. much more info on that experience in this thread: http://forums.bimmerforums.com/forum...d.php?t=687627
3) i did nothing. it just worked and it worked much better than when it was plugged in.

there's a bunch of info in that thread i posted above in reply to Balthazarr. you can also check out the link to another thread about unplugging the MAF in my sig: http://forums.bimmerforums.com/forum...d.php?t=751597

Jonathan,

Those are some great numbers for the mods you have, even though it's not quite 250whp. The way I would look at it is: 1) You're not too far off that 335i with exhaust (17rwhp) on the same dyno 2) Your car is still a beast performance-wise (beating e46M3s and hanging with slightly modded 335i's is no small feat). Most e36s that do this are usually FI'ed, and you're still N/A without cams. That's a great accomplishment!

he will not beat even a stock e46 with a decent driver...

[ELIBEEMER]

yeah your Air/Fuel looks like a rollercoaster cause you had your 3.5HFM disconnected...

thanks! i was hoping some people would take note of the comparisons.

wanna bet?

yep. unfortunately it runs better without it plugged in so for right now that's my only option until i figure out how to fix my software to work with the 3.5" MAF. After that, i expect even more power
