General Supercharged Header Question

[gwatson]

Hi guys,

I am seriously contemplating upgrading my ESS twin screw supercharger from stage 2 to stage 3, for which I need headers. Since my car is a right hand drive Z4 3.0, there are no off the shelf solutions. I understand a Z3M with an M3 cat will fit a right hand drive car.

So how do you think this will effect the sound of my car, bearing in mind I have an ESS backbox on already. I don't want it to be overly loud or have that straight through noise.... I like deep, but not too loud :) It sounds perfect just now, sound is almost as important as power and don't want to ruin it, still 440+bhp would be awesome :) :)

Are headers essential for stage 3? What other mods are involved in stage 3?

Are headers essential for stage 3? What other mods are involved in stage 3?

System components:

-Forged, lowered compression ESS pistons, 9.2:1CR.
-Uni-belt SC drive system with TS3 spec SC pulley.
-6 larger Bosch fuel injectors, TS3 spec.
-Perfectly optimized, dyno tweaked 330 TS3 MS43 ECU software.
-E46 M3 fuel pump and new fuel filter assembly
-Detailed, step-by-step installation manual.
-Heavy-Duty drive belt.
-All required gaskets, bolts and installation hardware for engine assembly is included.

*The TS3 must be installed in addition to a ESS TS2 kit (115-12) and ESS M52TU/M54 SC Camshaft Kit (117-01) along with exhaust headers. We also strongly recommend porting the exhaust ports 8-10mm wider with the installation of this kit to achieve optimal performance.

A high performance clutch is required and LSD recommended.

This kit is currently only available for:

-Cars with the MS43 engine control system. MS45 TS3 is expected in first half of 2008.
-Cars with manual transmission

Part number: 115-17
Boost pressure: 14 PSI
Horsepower: 450 DIN (Stock 225SAE/231DIN)
Torque: 520 NM (Stock 300)
Correction factor for drivetrain loss is 15% above RWHP as seen in dynograph (RWHP/0.85)

Max,

Looking at a E46fanatics posting, is pistons not TS4? I thought TS3 was a thicker head gasket which gets the desired compression....

As you say headers and cams are required for TS3 and make part of TS2+ kit... maybe the extra 30bhp from the TS+ kit will be enough.. well for a while :)

Hi G,

AJ confirmed that the pistons need replacing and the valve springs as well. He said the engine would be practically new internally.

You know well the extra 30bhp will never be enough......;)
