Hi guys, here are my results of the dyno session I had at Alan Jefferies Enginetuner in Plymouth today.

i've got the following mods;

JB4 G5 (Map 5)
VSRF Catless downpipes
VSRF FMIC
BMS DCI's
BMS N54 Chargepipe
Forge DV's
Stage 1 Hybrid Turbos
Quad Exit back box

Cae run on Shell V-power 99

Dyno Dynamics 4wd dyno. All runs were in 4th gear (MT)

So using the autotuning in Map 5 (boosting to around 15psi) it made 429.5bhp and 490lb/ft and the crank.

Whose turbos? I'd hope for more with hybrids... Only 10-15hp more than stock turbos.

On a dyno I'd be running map 2 for consistency. You might want to consider a back end flash too..

[Cerbera9]

They were built by The Turbo Unit.
What torque do stock turbos usually make?
Do you think Map 2 would of produced better results then over Map 5?

[Sparky68]

What spec are the turbo's? Still a nice result but as Phil said would of expected more.

[Cerbera9]

Just a mild stage1 with slightly larger billet compressor wheels.
I'll try Map 2 next time.

[phil200tdi]

Very good torque to be honest.

I suspect you had a slight timing drop (from autotuning) in the mid range and this impacted the peak number. To be honest dynos don't reflect the road all that well...

I reckon with a back end flash (free software) you could get a very nice gain.. More so with meth!!

[phil200tdi]

Did you log the runs?

[Cerbera9]

Unfortunatly i didnt log the runs it was all a bit of a rush tbh.

I'm I'm new this year to the 335i N54 motor so I'm not looking to wring the neck out of the engine as I don't think the clutch will take much more tbh, but would be interested in the backend flash in the future maybe, what sort of gains can be made?

A friend runs Meth on his Audi S4 and rates it highly

[Cerbera9]

I'd be intested to see more dyno print out from similar 336i JB4 cars ?

[Sparky68]

Take much more? Guys in the US running 600bhp +

[Sparky68]

I reckon you could squeeze a bit more out of it.

[Cerbera9]

600bhp + on a standard clutch???

[Cerbera9]

Do you think Map 2 would give slightly better figures then?

Phil(the knowledge)200tdi... I have read lots of stuff you put on here...

This man knows his stuff, very impressed....

After reading, thought I had better ad that Sparky knows his stuff too...

[phil200tdi]

Not stock clutch

With 490lb ft it'll have a limited life.. Mine made 510lbft and I replaced the clutch soon after!! Now running a spec stage 2+ Clutch and all good..

[Cerbera9]

Did you stay with the standard dual mass flywheel or switch to a single mass flywheel/

[phil200tdi]

Oem flywheel.

It's fine unless going serious hp.. The smfw's chatter which would be unacceptable..

Not really...

Just owned the car along time and experienced most of the n54 weak spots!! Plus I've pushed things hard.

Its' all about fuel, our 99 v power isn't anything special

Run meth and wake those hybrids up!!

You know more than most mate...... Not blowing smoke up but, you know your stuff so just thought I would say....

[Cerbera9]

Sounds like Meth is the next step then, I'll look into it, cheers guys
