S62 Ergen Motorsport Headers

Recommended Posts

Did a trial fitment of a set of Ergen Headers which are fabricated for M60/62 or S62 E30. The intention is to fit them to 8M3 in place of the restrictive factory headers.8151289689_5b512ea388_b.jpg

Our spare S62 had the privilege of posing next to 8M3 with the Ergen headers on.IMG_0802.thumb.JPG.1705cc7f2e5c21e05399bab1d2edfe8d.JPGIMG_0805.thumb.JPG.dc27edfd3a29817e3ab0f52415d92616.JPGIMG_0807.thumb.JPG.a8b46703c8581b4e9032512b63363730.JPGIMG_0809.thumb.JPG.16809401c5059b3261c4ff8b6b983149.JPGIMG_0815.thumb.JPG.72a6cb9cf3403ab5d168671ae092c474.JPG

Awesome. They should give it a good improvement. 

Wonder if the exhaust note will change much...

Keen to hear your views of how the s62 responds to the new pipes........it remains an itch for me......

Cost benefit views would be good when ready......

How much extra hp do you expect from these headers?

Very nice Ray, hopefully a fair few kw's released with after some dyno tuning. Are you still running the stock e39 m5 cats on 8M3 ?

 

Some information here about before an after using Evolve's take on tuned length headers and some DME tweaks :

I honestly didn't know the S62 used M62 manifolds. Chalk another one for those 90's BMW accountants.

No cats. Should be interesting. The link doesn`t appear to work.

Will you be dynoing before and after?

Had a reality check re. fitment. Would need quite a bit of modification to fit the E39 restricted space.Put this plan to one side while I focus on my S65 powered E87.

These headers will be saved for something else.

The headers pictured are quite different to the Evolve Medusa headers pictured in the thread Breakmywindow referenced in his post above.

Evolve Medusa headers are a 4 into 1 design, not the two into 1 design pictured above.

What problems were encountered fitting these Ray?

All the threads I've seen about fitting headers to a E39 M5 have been on a L/H drive vehicles but I see Evolve make Medusa headers for L/H drive E39 and RHD E39

The Mk1 Evolve headers, which are equal length 4-2-1 and have shown on dyno's to increase mid - high rpm range vs the Medusa's which mainly increase the high rpm range can be bought in the link below, for much less than the Meusa's..

I look in to these Russ Fellow headers about a year ago and it was around 3.5k nzd landed.

Just putting this out there if you're worried about having to dent pipes for clearance issues. Engine Masters on YouTube did an episode where they tested back to back dyno runs while denting the header tubing on a V8. They started with something like 550 - 600hp on the motor, then did some modifications to the pipes at random, resulting in denting or "crushing" the tubing.

At the end of it, they lost 5 maybe 6hp with the damage they did - which they also said could've been put down to the time of day, different water/oil temps etc. etc. So the conclusion is that, if you have to crush a pipe somewhat to make it fit/clear, the difference in output is negligible.

It's actually kind of interesting to watch because it almost destroys the whole theory around mandrel bent exhausts vs crush bent.
