SCT x4 Use and troubleshooting

[BBOX]

Torrie what meth mixture do you recommend using? I know Snow offers the Boost Juice and I have a friend who ran that on a boosted 3L in a 1999 Mercury Cougar, but it seems like a lot of people on here are running 100% methanol.

I would say 50-100% depending on your end goals.

Would we see any benifits of running 30% ethanol in the fuel with 100% meth being injected? 

[tmcphail]

Yes it would add octane and help add in the fuel system lost by the ethanol use.

Torrie, I just posted some new slips in the drag race section...

[tmcphail]

Rock on man, email them to me if you would.

[FoMoCoSHO]

Do you want all of them?

I got a log too.

[tmcphail]

logs and the good ones

This is awesome!!! Glad to see people seeing the benefits of E!!!

[tmcphail]

Agreed, downside is further fuel system output degradation compared to E0.

Agreed, downside is further fuel system output degradation compared to E0.

This is where I get confused. Theoretically shouldn't the E provide fuel headroom just like meth? The way I understand it, all meth does is allow you to run less fuel enrichment @WOT(higher safe AFR)...or am I missing something?

[tmcphail]

Look at the difference in stoich points of the fuel. You need much more volume (pump / injector / raw fuel system output) with E85 VS E0. That is the core. See your WOT FRP for proof of that.

Torrie, do you have a figure on drivetrain loss for the SHO? I calculated about 27% using stock dyno numbers.

Maybe this little discussion can shed some light on methanol vs ethanol in layman-speak:

SHOdded, are you getting tired of my noob questions?

LOL!
