My RX7SP build up

A few things here...
first, your brake booster is on the wrong side

I like the datalogging... but it's getting tedious converting all these numbers to something that I can understand

I'm curious as to why you think the EGT's went down by so much.

And that airbox is total sex.... LOVE it

After consulting with BDC and HC my theory is as follows

After consulting with myself my theory is as follows.......
Turbine expansion ratio is 1.55 on the new set up, it was 1.70 on the older set up thus 32% was "wasted" out the waste gate v's only 11% when running this turbo charger. The amount of heat held in by the smaller turbo is shown by the EGT and also the pressure (power level being equal) which I got as close as is possible in this test to demonstrate my point. Thus the EGT difference is down to the free flow nature of the turbine not retaining as much heat to make up for lower flow (energy balance to drive compressor is derived from heat, pressure, and flow rate) to keep the turbine spinning at the same rpm (to make the same power).

The car is also quieter on full throttle/power v's the other set up, due to a majority of the gas needing to go through the turbine, nice side effect

Yeah the air box and lots of stuff in the bay is SEX, I spent so much time making allot of it, its nice to sit back and just stare at it

More "box" for you

It's a ****

to work on, as everything goes on in a certain order, and you need lots of special tools but its something no one else can copy too, so pretty unique (kinda matches the car).
