Been wanting to hit the track for a while and drag bores me a little. Would rather watch 1/4 or 1/8 mile than drive it. With tracks like Sandown, Winton, Phillip Island and Calder Park within reach it's just been luring me to build something that goes, turns and stops well.

Will be assembling the car in the next couple of weeks so only parts pics at this stage.

Here's a few pics of it but better way to see it would be to hit track days and actually hear this thing. Will be fun and hopefully keep up with a few of the other cars in the club

looks like a fun toy

nice work on the manifolds and the inlet looks tidy as!

Yeah they're pretty text book hey. Damian of Boost Obsession made these ages ago for a bloke that aborted his project so I picked em up at a price worth not making my own for lol. Only thing better he could have done would be weld the gate to the turbine housing but I want to resell the turbo one day so it's fine where it is.

TRK in Sydney who is a mate of mine had some ideas he wanted to try for the plenum and he's done well. Again mates rates stopped me from DIY even though my welds have a long way to go haha

Wanna catch that VT LS1 on here if I'm lucky so should be entertaining

nothing like a bit of friendly rivalry!

Boosted 6 vs LS1, love it haha!

That plenum is HUGE....

Agreed. Bit bigger than I wanted it but function over form is what I like and I think it's well engineered. It's the result of many group piss up brain storming sessions haha!

It's only 3cm taller than the lid of a standard ecotec plenum but roughly double the width at the front n rear top edges at around 380mm.

It's not vacant space inside either btw

i honestly think your going to have the un-fair advantage in this case!

one question, why are you choosing to use kalmaker 3 bar over $12P 3 bar ?

i guess the kalmaker stuff works better with the dash and such ?

By that I take it you have added trumpets or Bellmouths to the entry of each runner?

I would have though that you would have tappered the plenum down toward the rear somewhat.

A good mate of mine in aerospace did some flow modelling for it. Being a plenum, most important is pulse timing/ distance between the compressor outlet and inlet to the runner. Shape of the plenum doesn't influence that so much I'm told but there are parts in place to redirect traffic so to speak
