There is lot of projects here, but very few or no dyno charts of them?
Do you know any links to dynoed m42's?

Hey Frankie, Not sure you have seen these yet but here are some links to some of the charts I know about.
There are lots of dyno charts out there for M 42 cars that are stock like,
Ove's site http://home.no.net/ovekvam/
BMWman91's site http://www.e30tuner.com/
BP's site http://www.esatclear.ie/~bpurcell/
There a few on this 318 project car part 1 and 2 are stock, but part 3 is on the Supercharger M42. http://oak.cats.ohiou.edu/~kramere/downloads/GRM_bimmer_2.pdf
There are dyno's on all the spec 30 cars { Most of them are 6's } http://spece30.northamericanbavarianracing.com/
Hope this helps

Any A/F graphs?
Sadly no :( It was just to see where the car stood. I might dyno again sometime this year with A/F

Stock M42 w/ebay chip

I got the AF graph as well, but I cant find it at the moment. The guy running the dyno said that it was tuned for power from the factory. The A/F was ~13:1 all the way across.
I kind of want to dyno with my current setup (Cams, MarkD chip, and K&N) but I think I'll wait until the stroker is done sometime this summer.

do both
-
m42 with some work done to it.... :p

turbo?
-
what kind of work?
Motor:
Custom 8:1 pistons (JE Pistons)
Cometic steel head gasket
whole engine machined and balanced (new bearings seals etc)
Garrett GT2871R turbo (running 20 psi max)
3inch exhaust all the way through
lancer evo front mount intercooler (unsure which evo model)
Wolf3D engine management
M&W igniter
oil catch can
custom turbo manifold
standard rods
standard cam
standard valve springs
Driveline:
8 bolt LSD 3.91 (prob change to 3.46 soon)
custom 4 puck clutch disk
custom fitted Ferrari 355 pressure plate
318i flywheel
316i E36 gearbox (cheap fix for now, first one blew after 80Km's)
Others:
greddy boost controller
boost gauge
E36 electric radiator fan
To Be Fitted:
NOS system
Currently the car is putting out 213Kw at the wheels.
a few days ago i took the car to the drags and the best time i could
run on 20psi and my stock tyres was a 12.9sec (quarter mile)
i think i can bring that down a touch more.
i haven’t got great up to date pics of the car yet, i just never seem to get
around to taking them....

why would you go to a 3.46 rear end?
how is the turbo lag on this thing?
and what kind of LSD do you have in it?
-
A 3,91 gets real short when you have serious power,
a 3,46 would probably fit the bill perfectly,

At the moment my top speed of the quarter mile is 179km/h
and the car is almost at top speed (5th gear and at about 6500rpm ish..)
this is due to the e36 gearbox, the e36 gearbox's have a different set of ratios which
has made the 3.91 diff geared short. If i was still running my e30 gearbox the 3.91 would
be perfect. When on the freeway at about 110km/h the rpm is around 3500rpm from memory...
Plus when i put a shot of nos into the car i will run out of gears before the end
of the quarter mile.
the turbo lag is not really existent. the car pulls away great and comes on boost
very smooth but also very strongly. but there is no real lag.
The LSD is a BMW one, rebuilt but a BMW performance place in Australia.
I don’t know what they did with it, i think just a standard rebuild.
I bought the diff off the shelf when the shop had a sale,
the diff was cheap so i didn’t really ask any questions...

custom fitted Ferrari 355 pressure plate
:eek: What was the reason to use this besides the bling factor?
-
:eek: What was the reason to use this besides the bling factor?
I just needed a pressure plate that would have a lot of clamp force...
the 355 pressure plate matched the flywheel spot on diameter wise.
it was second hand reconditioned so it wasn’t very expensive.
I wanted a clutch that could hold well, I knew I was going to turbo and NOS
the car so I just made it as strong as possible (within money constraints).
-
how much did this presure plate cost?
and how much were custom forged pistons? I'm debating doing that, or getting the S52 pistons shaved down... (I'm going stroker turbo...)
-
and out of curriosity what are the specs on that turbo.

The pressure plate (second hand, but machined) was about $250-350 Australian dollars
I cant remember exactly because it was over a year ago, and i payed for
everything in one go
The custom forged pistons were $625US and they are made to any specs
I bought them from Top End Performance.
and out of curriosity what are the specs on that turbo.
the specs on the turbo im not sure about, if you look up GT2871R
on the Garrett website you will be able to find them.

These are two gtech plots I took of the car just now,
These are "gtech HP" not to be mixed with anything else.

a little late to the party, but:

This is with a straight through exhaust, no cat, very open (too loud) muffler. And an aFe drop in filter. Everything else stock, in unknown tune. I was super happy with the A/F! :D
