Just dropped a deposit on some M Power - Trackday Project Car
- Thread starter Gibbo
- Start date
More info please buddy, not gonna buy it, but be good to know more about the car.
One thing, why build it but then never actually find out what his creation could do?
Right EGO Mode activated!
Guys check me out yo! Car nearly made 400BHP, my E-peen and EGO are through the roof, I might move to Florida as well and post regular to inform you about this.
Anyway, as planned took the car to Powerstation today to get a run to see what if any difference de-cats had made, first run below had some initial wheelspin but the power result and torque nothing short of fantastic:
We then did a second run, reduced dyno load, helps prevent wheelspin and it worked, got a little less power as the ECU pulled some ignition as things were getting hotter, but still a great result.
The below is a comparison of the Milltek 100 cel VS de-cat, it is clearly evident the de-cats give gains everywhere, a good 10 horsepower or so and as such are definitely worth while if you don't mind the odd smell and are happy to throw stock cats back on for MOT purposes.
Am absolutely over the moon with how well the car is running, I've gained nearly 60BHP with the modifications I have done which is nothing short of amazing on an NA engine. Lets hope the CSL ECU with Frank Smiths TTFS tune is as good as the Evolve one or even if possible better, fingers crossed!

That is some impressive gains Gibbo. I have not read much of this thread so apologies as I am sure you have mentioned what mods you have done, have you put in new cams and done other internal engine work to get more power?
Will the CSL ECU add more drivability and response and not more power?

Mods are listed on the dyno sheet.
No engine work, no cams, just very well maintained, right oil, right level and only ever Shell Vpower.
Yes CSL ECU is for drivability and adaptability, it won't pull timing anywhere near as aggressive as the stock ECU does and will be a much smoother drive due to utilising a map sensor for lower rpm's.

Ah, I should have gone to Specsavers!
That is epic gains from a naturally aspirated engine with bolt-on modifications. I bet she is fun to hoon around in! A proper little track weapon you have built. Good job!

Yep, the acceleration is rather mind blowing, quicker than the 911 for sure, I love just cruising at say 75mph with box in auto S5 mode, floor it let it drop/blip down to 3rd and it just pins you and acceleration is relentless.
The dyno history is this:
When purchased: BMC panel filter, Scorpion catback exhaust, Milltek 100 cel cats: 336BHP
With Evolve remap added: 367BHP
CSL Exhaust fitted: 379BHP
CSL Air box & UD pulleys: 364BHP, ECU pulled ignition as car was hot.
Took it to Evolve to check OK: 370BHP on their dyno which is always less than Powerstations.
Today with de-cats at Powerstation: 393BHP first run, 385BHP second as ECU pulling ignition.
With the CSL in I do not expect to make more peak power but the ECU will resist pulling ignition as easy meaning I make all my power a lot more and the map sensor makes drivability far improved in lower RPM range.
Plus the ECU pulls ignition so quick on Powerstations dyno because their cooling fan simulates 60mph, the problem is as they dyno in 5th my car is hitting 170mph on the dyno, hence things getting hot and the ECU started to pull/retard ignition.

That sound like a lot of fun, I bet you have enjoyed seeing it all come together and feeling the difference in the drive after each stage, I am surprised it accelerates harder than the 911!
Such a great engine in the e46 M3, lovely straight six screamer.
Did you have the limiter deleted with the remap or was it not actually limited to 155 mph from the factory?

Is the S54 strangled stock?
60BHP from just exhaust and intake bolt ons is a lot! As someone who has dabbled in N/A tuning before that is almost a 20% increase over stock.

Very nice!

Nearly all of the gain comes from the remap, which is because BMW clearly left a lot on the table in the ECU tune. Makes sense considering the CSL came along.
S54's with aggressive cams, vanos delete and Motec ECU, make in the 430-440BHP region.
Why did it gain 23hp going from Evolve's to Powerstation's dyno - were some bits added? Kinda lost in the number of mods
Explained in the summary, the car was hot and the ECU pulled ignition, hence the lower result that time at Powerstation, their fan simulates 60mph headwind, yet the car is reaching 170mph on the dyno, things got hot, hence the lower figure.
Last run on Evolves dyno was 370BHP, the only change today was de-cats and obviously dyno type. So I'd suspect on Evolves dyno it would be in the 375 region.
This is a good reason for the CSL ECU or CSL conversion as ignition won't get pulled so easily.
Yet Toms Merc was pretty much bang on, 525PS and it put down 516BHP today. A Carrera 997.1 C2S also ran, IPD plenum, GT3 throttlebody, it put down 354BHP stock, after modifications it was 357BHP, stock power on a C2S is 355PS I think, I should know I own one but no idea if its PS or BHP. Fact is the rollers seemed pretty damn accurate to me.
If they are out, it is not by much, car put down 370BHP on Evolves dyno not long ago with the cats in place. Now it is de-catted, both cold air intakes are plumbed into the air box and the colder weather helped prevent the ECU pulling as much ignition. So think its fair to say the car would be close to 380BHP on Evolves dyno as well.
Doesn't make much difference when gibbo compares all his cars on the same dyno. If the dyno over reads (which given the amount t if stock cars I have seen put down book figures on it, I dont think it does) then it doesn't matter as by using the same dyno for each comparison
I suppose the next step is engine modification? Or are you drawing the line at that?
Impressive results, - have you tried a standard e46 M3 in direct comparison? - I imagine it'll feel relatively dull by comparison, quite a feat in itself!
