S50 stage 3 Evolve tuned.. 335.9bhp

But wait abit... Gazza will be along shortly with his Evolve mapped S54

Z3cade · Post by **Z3cade** » Fri 22 Mar, 2013 23:13

Rule of thumb for M Roadsters...

Standard S50 = approx 305bhp

Standard S54 = approx 325bhp

Gazza · Post by **Gazza** » Fri 22 Mar, 2013 23:23

347 or 349bhp from my S54, can't remember

I keep telling you Gaz... Evolve stage 3 for your S54 = 360+bhp

Get some schrick cams in there

Hmmm.

In the old days my S50 dynoed a lowly 300hp.

These days I have more and I do feel sorry for all you ///M owners with a measly 300-350hp. You have to rev the engine so high to get that it must be nearly bursting. You have to press the pedal down so far it must make your ankles ache. Poor you, poor you.

........Deano, you should be ashamed...or at least a little embarrassed by your comments...

Last time is was at Evolve I saw a stock S50 make 323. That same day, my S54 made 324. Mine is stock apart from the Eisenmann race.

Stock the S50 is supposed to be 321 BTW

I think a trip to Evolve might be in order

I'd be up for that

Imran at Evolve told me 321 is unrealistic from a stock S50. Out of all they had dyno'd 305bhp was an average.

I have dyno read outs for mine from evolve.

Stock was 307bhp

Stage 2 ( exhaust, filter & map ) was 320bhp

Stage 3 ( added schrick 284 cams & map ) is 335.9bhp

siwilson · Post by **siwilson** » Sat 23 Mar, 2013 12:04

Averages are just that.

The one that made 323 was ///M Murfs

What sort go money would a stage 3 evolve set me back

Badman gee · Post by **Badman gee** » Sat 23 Mar, 2013 20:40

Real gains are by supercharger, not much by remap.

Z3cade · Post by **Z3cade** » Sat 23 Mar, 2013 20:55

Stock to Stage 3 on an S50 will set you back around 2-3k...

Biggest jump is stage 2-3

Schrick cams fitted and stage 3 mapping around £1650+

The differents in drivability is fantastic.. Instant throttle response and increased torque..

I've driven stock Z3m coupe and stock S50 roadster.. Compared to stage 3 they are sluggish.

Badman gee · Post by **Badman gee** » Sat 23 Mar, 2013 21:03

I've seen a standard z3m at Santa pod and a stage 3, very little difference in times and performance.

Not worth that money Imho.

Depends if you lift the redline to M3 levels

Badman gee · Post by **Badman gee** » Sat 23 Mar, 2013 21:07

Depends on the car, my m isn't sluggish at all.

I you want big gains, drive a 911 turbo or Tvr cerbera.

Z3cade · Post by **Z3cade** » Sat 23 Mar, 2013 21:09

Granted its not like adding a supercharger or turbo.. It's the drivability that changes.. Instant power.

Z3cade · Post by **Z3cade** » Sat 23 Mar, 2013 21:25

Dyno showing Stock to stage 3

= big difference..

Badman gee · Post by **Badman gee** » Sat 23 Mar, 2013 21:30

Not that big, not for the sake of 3000.

Very little difference in every day driving. Might give a benefit if you put it on the track.

No.. I can honestly say the biggest difference IS on the road driving.. Not track or drag strip..

Increased Torque and instant throttle response makes a massive difference and a more enjoyable drive..

Not slating a stock S50 by any means.. Just stating the difference is Very noticeable and not a waist of money.

Z3cade · Post by **Z3cade** » Sat 23 Mar, 2013 22:01

In a realistic world Stage 2 ( exhaust, filter & map ) makes a great driving S50..

Badman gee · Post by **Badman gee** » Sat 23 Mar, 2013 22:02

this is a forum and everyone has different views.

i wouldn't spent that kind of money tuning a non turbo car.

real gains are made by remapping a turbo car, up to and above half the power again.

nothing wrong with the standard m car, set that way by bmw.
