I decided to use a Glasair for the 4 rotor Reno racer.
That  means I need to move the firewall and pilot aft.

I think I will use one Maximite per rotor for the EFI.
Why not? They are low cost. I'll use another for the EFIS.
The analog inputs are high impedance so four or more Maximites
   inputs can be connected to one sensor if need be. Of course multiple sensors could be used as well. Lots of computer power and lots of redundancy as well. Motec and Haltech both sell a range of sensors compatible with the Maximite.

Same goes for the mixture adjustment pot on the instrument panel.

I decided to move the turbo aft of the engine now that I understand the turbo exhausts manifold better. It is exhaust gas velocity driven and not pressure. That will also simplify the motor mount.

I looked at a Lancair Legacy and it has the same aerodynamic problem as the Sea Hawker Glass Goose to a lesser extent. The Glasair tail cone is also five times stiffer in torsion  as well. It has already gone
400 MPH.

The gear box will be Alison truck TX based.

Here is what the engine looks like with the turbo moved to the back of the engine.
Less frontal area than the  TTC engine. Simpler intake plumbing.

Almost an ME109 or DB 600 V12 configuration :-)

Almost the same HP .

Should do 400 MPH no problem.

Paul,
Very similar to the set up I will use on Tom's Legacy! Turbo in the back works well.
Only major change is we will put the radiator and oil cooler in the beluga butt using
a mustang style scoop.

That is going to add frontal area, weight  and drag. Mine will beat yours :-)

They never got this one to cool.

The cooling system on the Glasair will fit under the cowl.

We will be racing each other and the rest will be left behind :-)

BTW I have an idea about shortening the PSRU. I'll send it to you soon.
