Has anyone bought the kit??? I've just checked out the website - looks superb!
My m42 is being rebuilt at this very moment, this is tempting as hell!
I don't know if its anyone off the forums, but he has sold some kits!I am hoping for someone to post some experiences with this kit on a bored and stroked M42. The size of the airbox and diameter of the runners could choke the engine at high rpm (8000) I guess.
I know the thread is very long but I have covered those questions, but no - it will not choke out at higher RPM for several reasons:
- The supplied airbox is twice the volume of mine
- The diameter is large enough to support 2.5L
- If you end up with choking from the ITB diameter, then your restriction would actually be the port area which is slightly smaller than the ITB area
- If you open the ports, you can also open the RHD manifold, and buy 45mm ITBs (which will also fit)
- You can run any length runners you want, you can buy them in 50mm increments, with 30mm trumpets - so if you really wanted to you could run the manifold +80mm. Though if you look back you will see there is no reason to do this.
The kit is modular, you can basically set it up how ever you want by just swapping out different parts.

I have had a look at the data from your dyno day, I've just been running around for Christmas! I will get to it!
I have an Excel file that the dyno made automatically which could possibly save you a lot of work. I can send it to you (translated to english) if you want to get a look at it. It lists all the power numbers every 5 rpm
