What power do you think my 1M will make?

[octainejunkee]

Ok,
so Ive owned my 1M new since March 2012,
Im not new to tuning and have spent the last year developing my 1M to ensure ive got the perfect set up to suite my taste,
The car is prodomently used as my daily drive and the occasional track day although i do have track/race cars to use on track so i only track the 1M with for a giggle rather than run it too within an inch of its life.

So my current spec is

Professionally hand made intercooler and full hardpipe kit (build thread to follow)
Catless 3" ceramic coated downpipes,
N55 Midpipes, (edited)

On the standard map it made

380BHP 415LBFT at the crank on a dynodynamics rolling road.

Im putting the impressive torque figures down to me retaining the standard back box
and the overall hyke in power down to the amazing intercooler & hard pipe kit which,
as soon as it was fitted made the car feel and sound far more aggressive. The turbo whistle is more noticeable now and the power delivery even without a re map feels much punchier and more powerful the higher up the revs you go..

So the car has been left with my carefully selected BMW race tuner for almost 9 days now, Ive had constant updates and progress reports and im confident the finished result is going to be a very driveable yet powerful 1M, if not the most powerful 1M in the uk???

So who would like to have a guess at the final dyno figures?
Il be doing a build thread before it gets mag featured, but for now i thought id ask peoples opinions on the spec choice and what power it'l make once mapped?

cheers Jamie

If you are this confident about the result it sure will be over 450 hp/crank. I think 1M can make 500 hp and 500 lb.ft of torque without changing turbos at crank even if you play it safely. If you want to break records you probably can go a bit higher but not much.

But I am saying this just because I like betting not because I have experience in tuning

So that's my guess, 500hp and 500tq crank.

By the way, did you want to say N55 mids among the actual mods list?

[octainejunkee]

Cool....
i'll just ad that the car is still being mapped
and im not aware of the final figure yet.

Also i've asked that they spend as long as it takes to fine tune the map to ensure that we're getting the most from the spec, however im not one to chase figures for bragging rights, if it turns out its not as powerful as someone elses then i wont loose any sleep, however having felt the difference the Intercooler made in standard form im confident it's going to shock a few people..

who made the intercooler? and how much did it cost?

It was a prototype with 90 man hrs invested in routing it perfectly& maximising the limited space available .
Obviously now the development work has been carried out and the cad drawings done,
we can work out the pricing for future off the shelf orders,
It really is a work of art,,,
Once the performance figures are released i'l chase up the pricing info and post them on my build thread..

[bdaddylo]

Hopefully, you're going to use the same dyno. My guess is +75hp and +45lbft. Can't wait to see you the intercooler build details.

[octainejunkee]

Yep same dyno
we dyno'd her upon arrival and she's lived on it for the last week lol...

The tuner has saved my stock map so we can switch back if we need to compare.
Also we can do some back to back intercooler testing to see the gains clearly.

Anymore guess's on power?

cheers Jamie

Well estimating crank power is kind of silly unless we all agree on a formula, and I would say, if we were and did , that you are already at 450hp crank. As a guess on your dyno power, would go for 435whp and 465wtq.

[Em/1]

Oops, I just notice that you said BHP for 380 figure; I assumed if talking dyno you would use whp since otherwise kind of arbitrary. Why don't you just stick with the actual numbers?!

[Smiley1175]

What was the baseline for the car prior to any mods?

[SpencerMH]

I would guess right around 400 whp and it seems hard to push significantly more power out of than similar tunes though you should have a more refined graph and smoother drive due to the custom tuning, good luck and interested to see this intercooler and piping?

Exactly, I don't understand the OP's post actually.

380WHP with the N55 mids/other IC and downpipe?
And now you want us to guess what (crank/W?)HP it will make since it's already more than a week @ your tuning specialist?

I'm always talking crank and PS/DIN (EU)HP, so for me it's kind of confusing sorry, but hey that's just me I guess(being EU continental)

In the uk everyone uses flywheel bhp figures even the manufacturers, hence thats what i'm using.
For you guys across the pond the question im asking is how much more power than standard do you think my mods will make? lol

I think the standard 1M is quoted at being 335/375 so the mods made a significant increase at 380/415 already.

As far as assuming that all re maps are similar and produce similar results i'm not so sure..

Plus, I'm interested in seeing how much better my intercooler is at keeping AIT's down (allowing more boost ) compared to what is currently on the market.

I'm also keen to see if there are visible benefits to ceramic coating the catless downpipes.
I'm a big fan of ceramic coating and had my race car manifold ceramic coated along with the down pipe and could feel the difference in throttle response and when on track the lack of heat soak was clearrly noticable.

Obviously its not the longest spec sheet.
There are future turbo mods (amongst other things) on the cards,
but i'm interested in seeing if it was worth my time to have "custom parts" made to my requirements as oppossed to going with the limited parts currently on offer..
It was a costly investment having a "one off" intercooler made especially with the much needed hard pipe kit all fitted to look oem to the un educated.
Im hoping the figures speak for them self and if they do the firm are prepared to make up a batch of 5 at a time for you guys that are intersted..


My initial guess was 465/500 based on other peoples figures but we'l have to wait and see...
Anyone else care to have a guess-only for fun there's no prize offered except maybe a passenger ride for the winner but then im happy to take anyone out if theyre interested in how the car goes??

Hi Jamie,

Now I understand. But as you might know a stock 1M already has some 335@ the wheels if I'm not mistaken. Flywheel/crank would be est. 355/360(?)already stock.

If you are looking to have turbo developed, please let me know and I will share the cost if we are after similar things. It would be good to know what you come up with for your FMIC.

Still running the stock airbox? Leaving a lot of power on the table if so.

Now at the risk of opening a can of worms...

The UK would appear to measure bhp at the crank and yet make the same power everywhere else does at the wheels.
BMW uk quote the figures as 335/375 at the crank for example..

A more knowledgable guy could probably explain the reason however, for my thread lets just say we'l look at how much power has been made from when i dropped it off with the upgrades on but without a relevant map to utilise the gains.

BMW NL/Germany quotes the 1M as 340BHP/450(500 overboost)Nm.
But that's just underestimated, keeping it from E9x M3 canibalism on paper. IRL it's 9/10 times the other way around.

I was thinking of looking into that next tbh.
Im not keen on swapping to cone filters as i want the look to be oem and also dont want too much induction noise,
(this was meant to be my refined daily ride after all )
Has anyone developed a Carbonfibre airbox upgrade yet as if so it'l save me a lot in development?

I'll keep you all up to date with the turbo upgrade aswell but i expect ill need to fit a stronger clutch before then so it wont be too soon.

care to have a guess what mine will make then?

You may like to go back and see what others in UK were rated "stock" at dyno. I remember UK crank numbers posted here before adding tunes like Evolve were usually around 360 to 380 bhp.

In another word, your actual few mods maybe did not add that much to stock car since it is obviously underrated from factory. You can't just compare advertised figures with your dyno after installing something, I mean anything. You have to make a "bone stock" dyno first to see "your" baseline. Then you may suggest this sticker added 2 hp etc.

Or I am missing something big time
