Finally, Dyno Results!!!

[scheides]

It's been a while since I've had the evo on the dyno with it running properly, but yesterday it finally worked out. The day before I had my doubts, as of course I blew open a massive 2" hose in my hose connecting my bov to my UICP and the car ran like crap.

I spent some good time on the street with my laptop and LC-1 getting stuff dialed in so as to minimize the headaches on shane, but really I probably only made things worse ;)

Anyways, mod list (power stuff only, of course):

Buschur Racing 3" TBE w/ bullet testpipe
Buschur Racing Intake kit
BR Deluxe FMIC kit (3.5" core)
BR Upper IC Pipe
OEM IX BOV
HKS 280 cams
ARP headstuds
BR Ported/Coated Exhaust Mani
Ported Turbine Housing
OEM Evo IX turbo
BR SS O2 Housing
BR Ported Intake Manifold w/ EGR delete
BR 65MM TB
Walbro 255HP fuel pump
4x Kracka Vent setup w/ ebay catch-can
Aquamist HFS-1 Alky Injection Kit
FIC 1050cc injectors
GM BCS
Evo X MAP sensor
Innovative LC-1
Tephra v5 ROM w/EGT Elim & Direct boost mods


Pump gas (BP 92), ~24psi, tapering to 22psi (woot! ecu-controlled boost!)

Boost curve needs some work, but this is my low-power tune, so it doesn't get as much attention as the alky tune :)

Anyways, on to the fun part!

Pump + Alky, 28.5psi tapering to 22psi

As you can see, the turbo is just out of steam and dispite my best efforts and 100% DC on the GM BCS, it just won't hold more boost up top:

Overlay, what can alky do for YOU?!?!

To flip between these two tunes, I have but to push the power button on my DDS gauge (part of the aquamist kit) and bam! The power is there :D While on the dyno, I tested out Tephra v5 mapswitching as I am using it for a failsafe. If the alky fails, I drop down to the pump gas tune. We did a pull, and I flipped the DDS gauge off right around 5000rpms. This seems like the worst thing you'd wanna do, but I wanted to be *sure* it was working!

Flip it off, and boost drops:

And AFR stays nice and safe :D Success!

Comments, Q's, and criticisms welcome :D

Nice.

I'm impressed. That's a bigger difference than I ever gave alcohol injection credit for.

:lurk: We want engine bay pics!

Very nice!

How safe is this alcohol injection kit? Is it something that can be relied on by an autocrosser? I just imagine myself installing it, getting tuned, then having it fail and popping my engine during a run.

Pretty stock-ish looking under the hood, nothing fancy. This pic is from when I finished my Aquamist install:

I have a better setup with Kracka Vent's and the catch-can now, it's a little different now. Perhaps some day I'll get one of the new FP Red's, and it'll still look stock-ish, but put down more like 420whp :)

His kit has a flow based failsafe, incase the pump is failing or the tank runs dry, I believe. And I think he has it wired so that if the main unit loses power that the ECU switches to the pump map. He shut it off during one run and it changed to the pump gas map without even a lean spike or anything.

Heh, please note the last two pics I posted. If something goes wrong, boost lowers, and the fuel and timing map from the base map (the pump gas map) is used. I have done this several times and logged *ZERO* knock during the transition. It is perfectly safe. Warrtalon on evolutionM ran an SMC alky kit and he autoX'd competitively with it for several years. He recently switched to E85.

That's pretty good power! I'm impressed :)

Well done Chris.
