progress on the inlets!





throttle body of a golf vr6 B) should be big enough..


ty to fit it..


this is to lower the compression to 1:8,0 and should also help to flow more around the valves, because normal they are near the "cilinderwall"

Thanks guys :D

In a week I get some other parts to try if it will fit.
Someone is now modifying my MS ecu for some applications I'd like to use like;

-ford pwm idle valve support. thats easy to make the engine idle smooth and it will regulate itself then.

-boost control: always easy..

-launch control/flat shift :ph43r: why would that be ? :wub:

Made my own triggerwheel today.
It was a universal wheel. its steel so you can't weld it to the alloy pully.
I don't know the name of the machine, but made it fit so good that it""clamps" itself to the pully. used 3 bolts for security..

That looks impressive.

It's nice when a plan comes together.

Hi Rutger - looks like your doing a fine job I must say, one thing you may want to take into serious consideration is the piston temperatures, even if you are using a trick forged race piston, its worth engineering a piston cooling jet spray bar set-up which will take oil from the main gallery and aim it at the underside of the piston nearer to the exhaust valve, but any area under the piston will generally suffice.....you may find you need an oil pump of about double the current mass-flow capacity (longer pump rotors), sounds like grief I know, but doing all this is better than melting your pride and joy, being air cooled its a pretty bad starting point to be honest......every turbo engine I have ever worked on (I have designed turbo engines for LMP900 LeMans and WRC) always has a set of piston cooling jets, and they are also now standard fitment on all turbo road car production gasoline and diesel engines......I have seen such systems retro-fitted to V8 pushrod engines which have since been heavily turbo charged, so it can be done, if you need more advice please just ask.

But otherwise it looks like your doing a fine job......make sure you form some kind of duct around the intercooler in order to force the air through it!

Knighty, what about water injection? There is a train of thought that says you inject a alcohol / water mix?
