And keep in mind please dont take the 'Peak' numbers to heart solely as there will without a doubt be dynos elsewhere that will read higher or lower than this one. It is simply to show power band differences as well as the capability of these setups with proper tuning.
"The Beater" My shop car: M52 w/ S52 cams and M50 manifold. Stock OBD2 headers and a nice exhaust setup.
Before on Stock US 328 tune (but with mods) and then tuned after 4 runs. Low end still needs some work (playing with vanos)
SpecE36 328: Customers track car build. Stock from airbox to headers, bimmerworld race exhaust after that. Stock then tuned.
Another SpecE36 328, This one with stock midpipe and M3 muffler
E36 328 Track Car: S52 Cams, M50 Manfold, Stock airbox and E36 Obd2 exhaust (including muffler) Stock tune vs tuned
S52 E36 with M50 manifold, intake, stock cams, and a variant of bimmerworld race exhaust, before and after tune.
The beater vs the 328 track car w/ M50/cams. Beater has 'intake/exhaust' vs stock e36 stuff on the other car. Note the significant low end differences but keep in mind these are two completely different cars...
Beater full tune vs SpecE36 328 full tune.
This is what an S52 looks like with WRONG cam timing, tuned it slightly off our off the shelf tune but the timing is freaking everything out (obviously)
E36 328, Intake, catback and M50 manifold. Needs cams badly or the stock Intake manifold, off the shelf vs dyno tuned...
Update 10/1
M52 with M50 manifold before and after tune.
(Eli)M52 with M50 manifold vs (Beater)M52 with M50 manifold and S50/52 cams
(Eli) M52 with M50 manifold vs Stock M52 with tune
2 Different M50's vs a M52 Stock (with our Tune), M50s are unknown whether they are chipped or what (we dont play with 413's. Despise them)
Update 10/7
Went to the dyno again yesterday to do another E36 M52, with M50 manifold and S52 cams. Had stock E36 OBD2 headers and midpipe, aftermarket intake and catback. Pre and post tune. (had an off the shelf shark injector before)
Update 10/8/14
Tuned a E46 M today:
Update 11/5/14
Alum M52 Z3 with S52 cams/M50 manifold. First run on off the shelf shark injector with cams timed wrong, 2nd run after fixing that and full tune, 3rd run was deleting the cat and making a better merge over the factory Z3 midpipe...
Update 12/18/14
M52, S52 Cams, M50 manifold. Dont have a 'no tune' run sadly. The fist run was on my off the shelf tune...
This Pic is before and after fixing the vanos and changing the exhaust merge from a magnaflow crap one to a nice mandrel bent one and adding a muffler in place of a resonator.
Off the shelf vs dyno tune (prevanos/exhaust work)
Progression of before and after on each prevanos/exhaust and post. You can see the exhaust mod affected it slightly up top but it sounds tons better!
S52 Dyno tune vs my off the shelf tune. Schricks, intake, 3.5" MAF, M50 manifold, 24lb injectors, stock E36 OBD2 headers, midpipe, and a UUC catback. Needs exhaust work badly to open it up.
And again 3.5" MAF and injectors does nothing to add power, was already on car when customer purchased it.. Didnt get a base non tuned run
Update 2/17/15
Tuned a M54 swapped E30 today!
Stock M54B30 with E36 OBD2 headers
M54 Vs M52 with M50 manifold
M54 vs M52 with M50 manifold and S52 Cams
Update 2/25/15
Tuned a powerdyne 5-5.5psi supercharged M50 mani S52. I had previously did a quick and dirty tune on it 4-5 months ago and thats the first run shown. The car then went from stock OBD2 headers/midpipe to a nice ~2.75" single w/mufflers and ebay headers which is run 2 on the same tune. I then retuned it from there.... MAF setup is now maxing out at ~6k where it was perfectly fine before the exhaust work. Thats the dip you see at 6k.
Update 3/2/15
Tuned another SC S52 and an S54 swapped E46 Touring we built.
S54 325iT, pre and post tune
Getting the AFRs where i want them
Another S52 SC car. This one is a VF running 7psi through the stock E36 exhaust setup.
This car we built with no tune that came with the blower and i tuned it from scratch. The first run is my base tune and then revising it to the final revision...
S52SC's Versus S54
Update 3/2/15
Customer Car came in as OBD1 S52 with M50 manifold and a off the shelf Name brand chip for said setup i wont name. OBD2 headers and a cone on the MAF. Brought car to shop, threw OBD2 harness/ecu/sensors on it, changed nothing else and results are below
Did 3 runs, based my other comparisons off the middle of the 3.
Stock US Tune vs OBD1. Dip is from vanos shutting off early because of missing VSS...
OBD2 Base vs OBD2 tuned
OBD1 vs OBD2
Here is the revisions on the OBD2. Playing with vanos after flashing my Off the shelf tune and tweaking slightly (bringing timing down as far as possible without affecting power). Back to back to back runs other than the ~1.2 min flash time.
So basically ~10w/tq from going to OBD2 with no other changes. My off the shelf tune vs fine tuning it on dyno changed nearly nothing (other than fixing vanos bomb) as ive gotten the off the shelf tune pretty down after a while.
Again there is the obvious possibility that the OBD1 tune could have been revised further to make the same numbers but my point still stands. This will be more reliable, smoother overall, and when it does mess up, give you meaningful feedback as to whats going on.
3/20/15 Update
Tuned another E46M3 With exhaust work (stock headers) and stock airbox
Progression:
And another M54B30 (this time in an E46) with no muffler, cone on MAF and stock everything else:
3/27/15 Update
Tuned an entry level IP car today. Had an AA tune on it from a few years ago. Tweaked a few things and we get magic!
M50 Manifold, Intake, Stock headers, track pipe and catback, stock cams.
Update 4/4/15
Bone Stock 99 M coupe. Shark Injector vs MMW tune
SpecE30 AFM tweak
Update 4/7/15
No tuning here, just a dyno to dyno comparison... Car is an M52 318ti, M50 manifold, S52 Cams, Headers, Exhaust, 3.5" MAF, BBTB
A shops dyno in atlanta with their tune on it:
Same car same tune on the dyno we use
(Switched run to SAE because the other shops dyno is run on SAE):
STD Run:
4/23/15 Dyno Rental!
Rented dyno for full day, dyno tuned a bunch of cars, baselined a few others. More to come later
S54 Racecar Pre/Post
10PSI SC M3 Tuned from Scratch so no real baseline if you will. Stock OBD2 Headers/Midpipe. Air to air intercooler VF V3
The Earlier 5.5psi SC car compared to this new 10psi SC S52 M3
SpecE36 M50. Bone stock from airbox to headers.
4/29/15
Tuned another ZM3 coupe with a Stock S52. This one has an M50 manifold though....
ZM3 with M50 manifold vs the earlier ZM3 with stock manifold i tuned a few weeks ago. Obviously not the same car but dont see any low end losses from M50 manifold. Both cars (other than the one with M50 manifold) were bone stock from airbox to exhaust tips including ASC TB and all
