NICE Videos as always Wally. Your car looks, sounds and runs great. That lap in the Race Taxi looks like a blast too.

Man Wally - you are having entirely too much fun! But you deserve it I love the onboard video - it sounds so awesome when you really get into it.Thanks for the motivation again - gives me some more hope for getting mine finished..

I hear you and your totally right of course, but it did take me 25 years as a privateer to be able to do this. Sometimes people see only this and don't know or tend to forget (not you of course) what was all needed to get there

Great videos dude! Love to see the car getting flogged on the track. Getting some hot laps around SPA is on my list of to-do's wherever I get over there. That ride in the "taxi" looks pretty fun, did it have much body roll to speak of? That thing looks pretty planted in the corners.

None, not at all. That must also be the reason the box goes round corners so well. Acceleration wise, that could be had with just more power I reckon

Finished the fuel upgrades by adding a catch tank. Sounds easy, but involves a lot more than you'd think. Adding an extra fuel pump (blue one my former pump) to fill the catch tank, making space for the tank itself, which meant rotating the water tank in my case and adding another return to the original fuel tank, which meant taking out the tank and welding the return onto it (after all the precautions of course).

But very happy with the outcome, which also involded placing all fuel pumps and the filter under the dry-sump tank, so I had no fuel up front in the wheel well anymore, which feels safer in case of a head-on collision.







Low pressure fuel lines have stuck-on fitment, but all high pressure fuel lines are now screw-on type (AN).

Nice looking work. As always.

Looking "busy" up front Wally

How do you like the camber/caster plates ?

[Wally]

Caster plates (thats how I had them welded anyways ;-)) work well, but more would have been even better as I now have about 3-3,5 degrees caster from 1-1,5 degrees before. Yes, they only did about 2-2,5 degrees, but positioning them any further was not really possible as you can see.
I think its my M030 axle pieces that give negative caster over stock, but idk for sure..

Nice pix Wally. I see you have a new addition on the rear. How did it work?

Hard to tell..only way to find out how well it really works is in a windtunnel and none of us have the resources to do that.
In reality, I would have to drive just over the limit and feel the car break out, then repeat under the exact same conditions with it...just not practical. It stayed on and my theory and gut feeling says it should work. Had great traction all day and the car felt really good, better then ever before, but tbh, I really dunno how much that relates to the rear wing.
Just copy what Porsche does with their GT3 RS and GT2 RS cars and you can never be far off I suppose. Plus I had no budget planned for this and just used my old aircooled.net spoiler and extended it so its out of the way of the intercooler and more in the air stream that leaves the roof.
That wasn't much help actually huh, was it?

Confidence counts for alot. If it feels like its working and your mind says its working and you have the confidence to push it a bit harder. It must be working (in one way or another).
