Time attack BMW M20 New PB + More Power

[KrautnotRice]

Very nice build! Car's looking "maaad" :)
Jealous of that GTX3071... isn't that the new billet wheel series?
I'm really curious when you hit full boost?
Was considering a GT / GTX2871 for my M20 for fastest spool up.
Also, did going from the log manifold to a tubular one increase lag at all?
Cheers and thanks for sharing!

Considering I changed turbo at the same time as the manifold its hard to comment on lag and so on.
I'm on Full boost (16psi) at around 3300-3400rpm.
I struggled to make over 300 with the log manifold.
Out on the track the response and power band is amazing.

Let start with the new video
(The noise is the tyre touching the flare, we have now solved that issue)

Heaps of updates!!!
After the first track day I found I needed to put Power steering back in, it was just way to hard to turn into corners.
Got a front splitter made up by a Friend.
Got a big APR-250 Rear Wing to suit BRZ, I'm getting some custom CNC mounts made up so it will be at roof height.
Had all the exhaust manifold, Dump and screamer pipe ceramic coated to reduced the heat, and look good.
Had Murray Coote at MCA Suspension Make me some Gold series Coil overs, They make some of the best suspension components in the world.
Reduced rear sway bar size to 16mm
Added solid Aluminium rear subframe mounts and diff mount.






Look at the car now!!!!!

So much awesome, good work on the progress. Why the change to the smaller rear sway bar? What bar are you running up front?

Your build thread, from it's start to it's track debut are what dreams are made of.
+1 for using a Hans - that's cool.

Murray and MCA Suspension did all the calculations When they had the car setting it up and 16mm is the size I need with his spring rates ect.

Thanks its been a dream come true, Yeah i'd be mad not to wear one if you watch that video look at the run off or lack of run off. the track was built in the 1960's with no safety in mind. I hit 230 kmph down that straight.

Am also getting my LSD Rebuilt https://www.difflab.com.au/BMW-188mm...ch-2-Way-45-45
And ratio changed to 4.10:1








My car sitting next to the MCA Hammerhead World time attack car.



MY custom Coil overs made by MCA Suspension, they are truly the best in the bussiness.




Front brake hoses are too long so I'm having them remade shorter.

Super clean build! The wing and splitter make that thing look nasty aggressive. :devil:

May have been mentioned earlier in the thread but who makes those carbon fiber door cards?

I'd like to know this too. Also subscribed to your youtube channel and hoping to see more race vids soon!
