crank shafts, guuuuessing 1.8 stroker

 

it's definitely the start of something........

 

Jan -
Looks like forged cranks that need a bit of machining and grinding before installation. Are these for the stroker motors?

 

Two unmachined crank shafts and one missing one. I claim victory. What's my prize?

 

like this?

 

1.8L Engine crank

 

Really..really..cool.

 

I'm looking forward to getting these in hand.... they are back in heat treating again....... should be shipping by end of next week

 

That one on the CNC is mine .

It now looks more like this.................

 

Jan,

Now off to the grinder after heat treat. What's the material, 4340?

 

right now it's unobtanium

yep you have it down pat

 

Im drooling
And I hope it is also made of UNBREAKABILIUM
Sweet looking piece

 

Looks like a work of art!! Maybe you should put one ina an Art show as well!!!

 

Your killing me...MORE INFO?!!!!

 

these billett cranks will be able to be made from 1.6L all the way to 2.0L
I have heard the oil holes have put in now and the cranks are in the heat treating process again. Final finishing will be next week barring some unknown hold up

 

Looking good Jan/RMW.

My Dad and I got back our crankshaft from machine shop in the late winter(Classic Mini). Hopefully by next summer it'll be spinning in our Turbo 1293cc. New A+ crank with 2" mains, 1.75" big ends, heat treated, modestly lightened/balanced, and oil ways worked over. With the 4 bolt center main cap it'll be good up to 7500rpm!

Very nice

So Lets ask this.
Whats the added benifit of buying one of these cranks for a 1.6
Over the stock one that is also forged?
whats this suppose to cost 1500-2000?

 

I'll have final pricing next week
should be stronger than the factory one

we can have them knife edged for racing , but the big advantage is the custom strokes that we can provide

 

How much gain do you expect from 1,8 liter?


Like this one made by Krumm-Motors in germany

 

Where you will see the bigger gains is when you shove more air through it compared to a 1.6L. The m45 is small but if you put a Rotrex or TVS on it watch out. For example the 2.0L with ONLY 13psi of boost and a turbo made 365whp and 308tq . NO 1.6L will get close to that hp/tq with such little boost

 

Then it SHAT itself

 

Paul your so perky How do you do it?
And how do you figure it shat its self.
Besides. The only way to find out how strong a motor is, Well blowing it up
You've blown up motors right?
