4 door golf chassis build - experiment

Thank you

 

went ahead and made the plenum flange. This one is for a sheetmetal plenum. I havent 100% decided on carbon fiber for the plenum yet, but If i do Ill make another flange to suit it.



its hard to see but the inner wall has a radius to it



and an artsy fartsy photo i took with instagram

 

Got the motor stripped down to the bare head-block-pan

A couple things I think I'm going to do.

Electric water pump rear mounted with radiator

Alternator mounted at rear of block just above where stock motor mount is. Hopefully smaller race alternator that turns off at high rpm. Under axle if at all possible

Oil filter relocated. Not sure where yet but I need room for the throttle body.

Valve cover shaved of everything it doesn't need. Large AN fitting welded to it for crank case vent

Crank case vents on front of block routed to titanium air oil separator behind strut tower

Motor pushed back around 3 inches from stock location.

Possibly turning down intermediate shaft to cut out some weight

Manual timing belt tensioner

Adjustable cam gear

 

On another note I've been thinking about this car and torque steer

At under 2000lb - 907 kg and around 400 wheel hp and 275/35-15 Hoosier a6 slicks, I'm thinking torque steer may be an issue. Ill work out all the scrub radius I can in the suspension design, but you can only do so much.

I am thinking of running two short axles and an intermediate shaft like a lot of new high hp fwd cars.

So to you high hp mkII owners, is torque steer an issue?

 

There's an OEM "equal length" driveshafts (axles) solution from, I believe, early Passats.

Its from the B3 or B4, IIRC, (not sure you have those Stateside...). The "intermediate" shaft bracketry bolts direct to the block, and it (should) utilise 100mm flanges.

 

Thanks for that info, ill definitely be looking into that.

 

That inlet is a work of art

 

Any news how's it going?

 

No progress lately. Looking for a 2 door shell, working 80 hours a week and building my garage at the same time.

 

I know what you mean just keep us in the loop when you do some more super dooper work

 

Looks like I'm getting a set of kw clubsports from a c6 z06 corvette to use on the golf.

 

Nice...!

 

Just read through all of this, and i'm so glad i clicked in here.
Fantastic engineering skills. I will look forward to any updates

 

So as usual my plans have changed, kind of.

I still want to build a 2 door chassis with my 1.8t, BUT I want to run a passat trans in the REAR.
I'd build a torque tube setup similar to a corvette or 944 Porsche.

Dual upper and lower wishbone suspension both front and rear, with hydraulic ride height adjustment. One off spindles, aero, chop top, etc.

 

So you're just going for an easy oe spec restoration then lol

Going to be epic if your previous postings are anything to go by

 

Well I finally welded the two pieces together

 

Stunning work as always thrux, keep it up and keep us posted

 

Yes your fabrication is awsome we love it
Do what you can when you get chance and please keep clubgti posted

 

Here is the design idea for the plenum. Note this isn't to scale, just a quick sketch to convey my design idea.

The goal is smooth non turbulent flow and more equal distribution than your regular side feed manifold.

Opinions?
