GB: schrick cams and valve train parts

[maxx-automotive]

Hello, we have a group buy going on schrick cams and valve train parts
for all BMW engines.

please see: http://john.gmstech.de/schrick.html
for part numbers and pricing.

if interested, please contact me at john@maxx-automotive.com

we also carry Dbilas 6 TB conversion setup, alpha N, and have a
CF airbox in the works.

what are the group buy prices, and how much for dbilas- i can't afford it but i am curious.

[maxx-automotive]

you have to click on the link that was given above.
all the schrick parts with prices are listed there.
a dbilas runs around 1300 euro.

John,

Plan on posting this on S14.net? and bimmerforums? You'll probably get more people in.

John,

Email sent on some Other items. May be in for some shrick items as well.

i might be down for a cam, but i am not sure yet. need something to take the car to 8k like my rockers :).

Do you have valve springs that can handle 8k? They are really expensive from ppf.

[maxx-automotive]

most people I know with tuned M20 dont go beyond 7K rpm for
longevity. with schrick valve springs, a few go to 7500. it really depends
if you plan to occaisionally go above 7k, or if you want the
engine to actually live at those rpms (e.g. racing).

the 2 valve head doesnt really have breathing for such high rpm.
revving to a particular rpm and actually making power at that
rpm are 2 different things. the stock S14 head e.g., which has
a more efficient combustion chamber and 4 valve per cylinder,
is done making power by 7k rpm. you can rev it to 8K, but the
power is dropping off.

one reason to go for individual throttle bodies (other than
reducing throttle loss and increasing response) is that they
support larger valve lifts at TDC (more overlap) so you
can run a larger cam while keeping the idle more
stable == more civil. If youve done that, then of course you can
toss out the AFM and install an alpha N like we use. That also
improves the streetability of larger cams and bumps the torque
at all revs.

remember there is a time schedule for the GB, and should you
be interested, it is IMPORTANT to email me directly to put your
name on the list (I manage the GB list).
I will likely ask for payments around mid may
once we have a clear picture how many participants we have.


if there is intest in the dbilas Im sure we can do something there too.


Mike, Dave (OZM3) posted it on DTMpower in the australia sub-forum.
and I posted on the bimmerforums GB section.

what is the USD price on dbilas.

[mspiegle]

Does the Alpha/N work for the M20? Does it piggyback and trick the ECU - or does it directly drive the injectors?

You are on the internet. Find the exchange rate and figure it out!

Yes, Maxx alpha N works for the M20, M30, S14, S38 (3.5l), S38 (3.6l),
M88 (3.5l) and also have it running on an M50 with Dbilas ITBs and
carbon airbox, the same airbox/ITB setup will also work on a US S50/2
motor.

HOWEVER -- unless you remove the stock intake manifold and go with
individual throttle bodies, the gains from alpha N on a stock motor
are not so large.

the gains are larger on ITB setups, because having an AFM in front of
an ITB setup is similar to putting a single throttle body in front and
causes a flow restriction and reduction in throttle response, so deletion
of AFM and replacement with alpha N makes more sense.

If you run different cams, then the flexibility of the alpha N is nice
to have. Because you can just hookup your laptop and tune on the
fly (while the engine is running) -- changes take place immediately.
It is very simple procedure.
I often tune alpha N setups on the street, but you should have a
wide band lambda guage installed so that you can accurately measure
AFR. see innovate motorsports or www.wbo2.com e.g.

once you have that sort of setup installed, then you can think about
playing with intake runner sizes (for the ITB) and plenum volume/shape
to make a carbon plenum (known as an "airbox" in europe), this
serves as a cold airfeed from the front bumper, the carbon is an
excellent heat shield and keeps the air cooler, the increased plenum volume increases efficiency and the intake runners can be tuned for
torque/power or a combination. The larger the cam, the more
this sort of tuning pays off, and larger displacements accept larger
cams more readily, as long as the top end can breath. Its all a system.

i didn't feel like it, and your so right i was just being lazy.

I didn't realize alpha N worked on the m20, i thought that was a purely s14 deal. good to know.

is there a complete price list for all the stuff you carry. I see the cam prices but a lot of the stuff you are talking about is not listed in the price list.

an Alpha N setup costs 750 euro + shipping. It includes
the unit, sensors, wiring harness, software, base tuning maps.

Alpha N with ITB for M20. How much?

Thanks.

[DrMcDave]

Thanks.

2000 euro based on the listed prices he gave for the two individually. sick setup if you can afford it.
