Please note that this was a 3rd gear pull because during fine tunning the dyno AFR meter went bad, causing us to cut short our dyno visit and not complete with a 4th gear pull which is an actual 1 to 1 ratio

Also this was on 93 octane and at 24lb of boost.

 

Can someone explain the difference made by the gear ratios? Would it change the power output?

 

the transmission reduces the speed of the wheels per the speed of the engine via gears in the transmission.

thats why you're supposed to dyno in 4th gear because the ratio is 1:1 in almost every car. the transmission doesnt multiply the tq at all so the numbers are usually way closer.

 

that alcohol injection allows for some amazing boost on pump gas. You are using a standard water injection setup (aquamist etc) and using 100% alcohol? also, what specific kind of alcohol?

 

2 rotor 400tq ???

 

At 24 psi, sounds about right to me .

 

The Evo guys around here use ethenol or methanol, just walk into Ace Hardware and buy a gallon. It does make some pretty crazy results. My buddy gained about 30 hp in his evo just from adding alcohol injection. I was skeptical at first but he's had it on his car for maybe 6 months w/o any problems.

 

Nice power curve. Congrats!

 

Your not kidding. That is a smooth spark..

 

damn..didnt think it would make that big of a difference. On 94 pump without alcohol the most you would want to safely run is about 18, but to run 24 just by adding alcohol inj- DAMN. I will have to look into that

 

What ignition setup are you running?

 

Nice, I plan on doing straight methanol on the 18th. I got a pretty badass seutp going down, shooting for 22psi on my AF61r. I hope to achieve similar results =) Nice pull.

 

Im not sure you know what your getting into. You can't just "fill" up on methanol and think your good to go. When you run straight meth., you'll use twice the fuel, meaning you'll need twice the fuel setup, twice the injector and so on.
You have no need to even run it anyhow with that small turbo. Only straight race cars with large frame turbo's running 40+psi run it.

 

Duh =) It's methanol injection silly. It's a dual 375ml spray, spraying at 12+ psi. Using a 220psi pump, and a boost sensing injection setup. It's going to be tuned for methanol spray after 12psi. Meaning I'll be on pump gas, and spraying methanol through the intake so it's atomized.

I'm insulted.

Sorry I didn't make it clear that it was methanol injection. When I say straight methanol I mean not a 50/50 mix with water... lol. I'll be running straight methanol injection. But I can see where you're coming at by the way I stated it earlier =P

 

Good reason why I was CORNFUSED. I couldnt figure out why you'd run meth for 22psi....lol...sorry.

 

lol

Yeah it's all good, I should have clarified.

Besides the AF61r's best eff is at 18psi, anything after say 25psi will be pointless =/

Maybe I'll switch to a GT40r down the line, or even a 42r, we'll see.

 

I actually want to install a nice meth inj. kit on my car. You have any info. or link for your kit? I thought it would help make more power at 35psi with the C16. And my GT42R is kinda on the small side. Its only a 72mm compressor with a 1.05 A/R.

 

Yeah bro, I got a badass kit... it's pretty sweet. Hit me up on aim/yahoo under dhahlen and i'll throw you the specs, website, etc etc.
