today, started using the secondary injectors spraying VP M1 methanol


M1 methanol + water + careful programming of transition = DELTA P!

GT42 is the light blue line/green for turbine.
Red is intake manifold pressure, yellow is turbine pressure 1

Note the green line in the top graph, that is MAF lbs/min. It has been flattened in the CAL to reflect the M1 systems addition to the total fuel load. The white line at the bottom Graph however is raw MAF frequency and truly should reflect mass flow changes... Although it slowly increases with RPM it seems to plateau more or less once 32 psi is achieved and the transition occurs of turbos.
If you run it setup for absolute mode on the primary gate (PR High in green graph #4) and keep that a steady 2-1 PR, system response is faster, but Delta P overall is negative by a half Bar or so. The twist comes with the MAF freq more or less is the same in either mode, having a positive delta or negative at the cyl head.

Initial dyno run at mustang dyno

440whp at 33psi

It is as far as it can go today without changing the LP turbo gate spring.

SKY888

baby steps........since a lot of stuff going on with the interactions of the two turbos.

Need to be careful


at 35ish psi




still has a lot of bugs to fix............and will at least boost 40-45psi

Of course, another speed bump on this build


Engine started over heating, and BTF saw that on my killer glass radiator tube (transparent glass), coolant wasn't flowing). He suspects that water pump died

Anyone out there have an OEM evo x head bolt that they can measure for me? Need to know total underhead length, thread length.

Thanks!

Great Read, Nice build

Well, after several years, LIPSTICK is finally coming back!

Lots of changes since I received my car last year from BTF. After a few months, noticed lots of issues
- oil, fuel, boost leaks
- 4 bar map sensor used by manifold and 3 bar sensor on another....using 4 bar map tune! Wtf! No wonder the car never ran right.

So I went to Six Sigma tuning, owned & operated by Kevin Jewer. He is actually the one who inspired me to build a compound turbo.
He drag races his 7 sec compound dsm

So he took my car to fix all the issues, and run the compounds properly.

Last week, Here’s the initial dyno run for the 116 octane tune that produced 535hp & 480tq @ 39psi.

Here’s what my compound turbos (gt2860rs & gt4294r) are doing.

It spools 29psi at 3500rpm, but I think we can even bring it down to 3000rpm

Hopefully, with more boost (5-7psi) and extra 900rpm, it will make more. So we’ll see......

Recently, tuner Added 5psi, LIPSTICK is now at 560hp & 520tq. Very broad powerband now.
Previously, it was at 39psi, 535hp 480tq.

We are currently experiencing spark blowout even at .22gap. This is our current limitation and not even fuel!
We’ll try using copper plugs instead of iridium and do one more day of tuning. If that doesn’t help, we’ll wrap it up.
