S4 B8 tuning.

[The Pretender]

Based on new info it would be possible to get ± 400 hp out of the new 3.0TFSI V6 supercharged engine.
I expect MTM to be the first with a upgrade on the market.

I wonder how close a modified (400+hp) S4 will get to cars like the M3, it could be a good pointer as to the expectations of the new RS5 and RS4.

Only if they get the 3.0TFSI V6 Supercharged engine.
With a V8 under the bonnet it will be a different story.
The new 3.0TFSI S5 will prove that over the old V8 version.

What new info is this? I do check MTM's website quite frequently but nothing yet. Any ideas when we might hear something?

Most likely IAA Frankfurt or later @ the Essen Motorshow.

iam dissapointed, 400 hp is not much for 333hp base and supercharger.

[Mr Balsen]

it is 20% more than original. Not quite bad for a start.

After it depends on the exhaust, the cooling and many other parameters. I will keep you updated...

If you take the 560 hp MTM 4.2 supercharged V8 then a 3.0 litre Supercharged engine will end up with ± 400 hp.
And the 6.2 litre Supercharged Corvette ZR1 have just 647 hp. (± 313 hp by 3.0 litre)
Based on these two cars 400 hp is almost the limit for the Audi V6 Supercharged engine.

oh man thats why i like turbos more. look at 335i with 306 PS. you can get much more horsepower even with a chip than the S4.

[Leadfoot]

I don't agree that the limit of the S4 engine is 400hp, it may be the upper limit with the stock equipment but the engine would be basically the same whether it was attached to a turbo or a supercharger.

Remember one thing, there ain't any 5000+hp dragster that use turbos so there is nothing wrong with the technology.

@tvrfan,

Find me a chip only 335i that is genuinely producing 400hp and another thing, it's common knowledge that the 335i produces a lot more than 306hp. I suspect that the two engines are a lot closer in actual power figures than BMW are letting on. ;)

[Marv]

For me a MTM chip/pulley combo giving me 10-15% would be perfect. You get the best 'bang for your buck' in that range. I'm sure there will be other more extreme possibilities for this engine but the cost just goes up too much for my pockets!

Still, I'm looking forward to hearing what serious tuning emerges though...

Of the top of my head,PROcede produces 390HP. I THINK that’s the fasted kit available without exhaust/intercooler/air intake mods. U r 100% correct about the 335i performance output. U can imagine how much faster this car will b when it gets a hp increase later this year.

Leadie,prior 2 buying ur S5 we had a conversation regarding the 335i.U were praising it’s performance & claimed that, that was the BMW 2 buy.U went as far as 2 suggest that I should buy 1. I dismissed the 335i as the poor man’s M3. Nobody likes to admit that they are/were wrong but If I had listened 2 u I would have saved myself allot of aggravation.

I did not know that, but if the 335i does indeed produce as much power as the S4 (or there abouts) then this would be the upper limit of HP without other modifications as is the case with the S4.

I just don't agree with Jarod that 400hp is the limit period.

P.S.

I heard the 335i will be readjusted to 325hp, is that figure correct and if so then what it the projected 'true' rating of the engine?

[Mihnea@MRC]

335i producing 390 crank HP with just a piggyback (Procede whatever it is)? LMAO, maybe for a few short bursts of power, fine, but if you're going to try to do a top speed run, good luck keeping the turbos under the bonnet. I know it because I have spent a good few months developing a remap for the x35i....highest numbers we've had without mods was 375 crank HP on a car that dynoed 310 stock...

And for the B8 S4, we'll have to see what the engine has left in it. Aluminium block might not mean exactly good news but let's wait and see :)

BMW has deliberately & significantly underrated the 335i’s horsepower AND torque numbers. Some magazines have claimed 350hp....I suspect those cars were dynod in fantasy land.

Officially; 300 hp & 300 lb-ft of torque.
In reality; 329 hp & 331 lb-ft of torque. (0-100km in 5.3 seconds for manual & auto.)

420HP measured on what dyno and what octane? 100 maybe, I wouldn't doubt it, but on 91 or even 93, no way, not reliably...

They use various dynos such as DynoJet & Dyno Dynamics 2 do their testing.

Previous post clearly details what octane was used as well as performance times, reread that post.

Nice 405 hp / 510 Nm of torque.
No price though.

I don't even think they've had a car yet to test anything... but let's wait and see. So far, the ECU cannot even be read in the B8 S4, nevermind programmed, so that's where my doubts about B&B's claims come from... password protected memory access in the ECU will take a while to get cracked IMO.

That did they say about the GT-R also and it was cracked very quick.
Another option is a piggyback, give the engine different info and it will change the parameters.
