Title: Lightened crankshaft for m42 m44 stroker
Post by: max321 on January 22, 2015, 04:58:54 PM
Hello to everybody, i am new to this forum.
Let me introduce my self, we are company based in Europe that manufactures, and tune racing parts.
Here are some parts we do:

Header, lightened and balanced crankshaft 88mm 12.7kg for high rpm (28lbs)
Curently we have one stroker kit for sale with with crank 88mm, Mahle forged pistons 85mm and PAR engineering rods.
We manufacture big brake kits also, we do head porting and more stuff. Soon i will upload more pictures.

If somebody is iterested at buying some of the parts, i can upload more pictures.
Feel free to email me for prices, and sorry for my bad english.

Welcome!

I have a few questions  8)

1.) How much is the crank lightened from stock? Has the snout and key way been modified to fit the m42 or will it need additional modification.

2.) Will the header Fit LHD? Any dyno numbers by chance on this ?

3.) Can you tell us more info about your company? Do you guys have a website?

Thanks! This is very exciting!

Crankshaft is lightened about 11 lbs, we do all machining and no additioanal modification is required. Header will fit LHD. We dont have any dyno numbers yet, but are sure about perfomance do to our expirience. Dyno will be done in march.There are 2 options with header design, difference is in tube diameter.

Company is based in Croatia EU. website is in progress and will be online soon.
We have large expirience in tuning cars rallying and hillclimb racing.
Our specilities are big brake kit, head porting, bigger valve seats, and everything that requires machining.
If you have any more questions feel free to ask.

Here are some photos of our work
Central locking Porsche
header in progress
bigger valve seat in progress
head porting
and also big brake kit that we manufactured for e46 m3 380mm

Hi
Great to see this happening.
How much weight have you taken off the crankshaft?
I know they are heavier than the m42 crankshaft with there 18 mm counterweight compared to 15 mm m42.
Also what exhaust cam is the manifold set up for and pipe sizes, rhd?

Cheers Rohan

As i mentioned, crankshaft 88mm is lightened for 11lbs. Oem weight of 88mm was about 39lbs, now  is 28lbs.
2 headers are availble, 40-45mm piping, and 45-50mm.
First one is for lighter tuned engine and 45-50 is for high tuned engine.

We dont have any access to rhd, so we dont know if it will fit.

Prices are:
Header 750 euro
Stroker kit 1500 euro
Crankshaft 800 euro
Head porting, valve seats, whole engines are possible too, and etc. depends on stage of tuning.

Prices are:
Header 750 euro
With your header i can use an M5X system?? with a modified flange that fits to your header?

Yes, this is possible.

Interested in the stroker kit. What is the final compression ratio? What would be the final displacement? Would this setup be suitable for a street car, or is this more for a race application?
Title: Re: Lightened crankshaft for m42 m44 stroker
Post by: max321 on April 02, 2015, 05:04:34 AM
We have applications, compression ratio can go from 11.5-12.5 with 88mm  stroke and 87mm pistons, in this application original con rods can be used. Pistons are not forged but are very strong and lightweight, witch is perfect for street use. this combo gives 2093ccm. Other combination is with forged pistons 85mm, this can also be used with original con rods, but we offer forged aftermarket con rods. This combo gives 1997ccm. Compression ratio can go from 11-11.7 This is more race oriented, do to forged pistons and keeping the displacement under 2000ccm.
Last combo is also forged and lightened crankshaft but stroke is 83mm and 87mm pistons. This gives 1974ccm.
We can recommend compression ratio witch is most suitable for your needs.

My intention is to build a 2-2.1 stroker. I have been looking into the various options, such as the m47 crank and s50 pistons. The m47 crank has an 88mm stroke, which is what yours is offering. Also, your crank is lightened to 28lbs, a savings of 11lbs? Is your crank a machined m42 crank? I would actually prefer the forged pistons, however would an 86mm bore instead of an 87 be optimal? From what I've read, an 88mm stroke (m47 crank) and 86mm bore (s50 pistons, shaved 1.5mm) would result in nearly 2.1l and a near stock 10.5-11 compression ratio. If that's the case, I may just buy your crank and then shave the US s50 pistons myself, unless you have forged pistons that you use and would recommend.

This is mainly going to be a street car, driven 3-5 days a week with some eventual autocross involved. My m42 just died and if I'm going to rebuild it, I might as well do it right. What would you suggest?

Also, you said that your power numbers would be run in March. Have you had any dyno results? Do you have a picture of your machine process? Pics of any installations that you've done?

Yes, crank is lightened for about 11lbs, it is not reworked m42 crank, that would not be possible to do. Well, there is no optimal setup, with 87mm pistons and good head gasket setup works fine.  As we have no access here to us pistons s50 i dont have any specs. If pistons are shaved flat that would probably end up with commpression ratio bigger than 10.5-11. We dont have forged pistons 86mm to recomend, s54 s50 euro forged pistons can work but have to be shaved more than 4mm. It would probably work with these 86 us pistons, however we recomed our 87mm lightweight pistons. No dyno numbers for now, i can send you some photos of our engines. I will send you photos. If you have some more questions feel free to ask.
