Super sprint Manifold (RHD)

The Gorilla · 04-03-2010, 10:08 AM

Hi,

Guys, I think your overlooking some
key points here.

1/ The North American Cars [E46 M3] have the Cats
just below the header, hence they are around
10-12 bhp down as oppossed a Euro car.
ie] there rated at 333, as oppossed the infamous 343.

Some NA cars have posted gains as large as
15 BHP with Euro headers and Cats, you go figure !!!

The Super sprint header will give no more than
8-10 BHP in the real world, if really lucky.

8-10 S/S gain if lucky, plus the 10 BHP that your
North American Cousins are down and hey,
20 BHP gain on Headers, Hello.

F1 has had good results and success with stepped
Headers, but the exhaust scavenge process of a
F1 Car, combined with the fact that there
are No Cats to impeade the exhaust Gas
out flow once its exiting, has more to do
with the results than a larger pipe into a
larger pipe theory.

BMW Motorsport actually make a large bore
Header for the S54 engine, which was of
course made for LHD only.

KK Automobile do a very good Header which
I think is around 1350 euro for a engine
upto 400 BHP plus.
Again these are for left hand drive cars
so the steering would be a problem.

Why not do a Group Buy of say 5 or more
of the KK S54 Header, and I am sure Sven
will make a RHD, as this will also give them
the pattern from which to be able to sell
others.

And if your Normally aspirated S54 ever makes
more that 420 BHP you can call BMW Motorsport
and tell them how its done.

.

id be happy with 380bhp

My headers are on and its being mapped as I type, I will let you all know the results.

Although mine is a bog standard M3 so Im only expecting 370 max, coupled with my full system and carbon airbox, csl spec except for the cams.

But put a standard csl on a dyno and it will not be 360bhp prob 345-350.

People do get drawn into peak power talk, A well mapped 345bhp peak will beat a poor mapped 370bhp peak powered car, esp on track.

Its all in the mapping.

There's an easier way of getting 380 BHP

My concern would also be the cost outlay versus power gain returns. Presumably this bit of kit works best with a full exhaust setup and ECU remap - not cheap as we all know.

I already have the full SS exhaust solution minus race cats so it is an option, but at £1600 - a rather costly one. I might be persuaded in a discounted group buy of course... (Cue ridiculously long and protracted Manifold Group Buy thread!)

I thought you only had an SS back box Rob, do you have other sections as well?

Hi,

I think the CSL is about 355 BHP ish although
have made a few changes which may
have altered it by 2-3 BHP.

Ie AC deleted, etc.

The CSL engine in the E30 M3, no cats
twin 60mm Exhausts, only one box,
running on Motec M880 made
365 BHP on the Dyno and it was
pulled back a bit at the top, now 355 ish
to give a bit more grunt lower down.

Will 1600 pounds worth of Super Sprint
S/S give me 10 BHP more, I very much doubt
it.

Regards,

The Gorilla.

Entitled to your opinion of course. However I'm happy to refund anyone (applies to all of our upgrades) if its doesn't do what we say it does - same applies to any business really.

Hi,

Derek Musch at Musch Motorsport
had a S54 almost to full works spec
here is a pic of a BMW Motorsport
Header.

Yeah we know Musch, nice guys, we are working together on a few things actually.

Some interesting info from JT and The Gorilla.

John, would my car with cat-back SS system see any benefit from a SS manifold? I would rather keep the cats standard ideally - would this restrict flow and therefore additional power?
