Wb02, Alky & Afr

[LBS Blown Buick]

Not shure where to post this so here it goes.

I was woundering what AFR to run at WOT with a 50% water/ ALKY injection mixture.
It seems to richen the mixture at the WB02.

this is a supercharged 355 smallblock in my Camaro.
9.5 CR 7psi boost.

Normally a 12.5 to 1 for Gasoline.

Its seems that maybe a 11.0 to 1 with the Water/Alky injection
on is more in line.

Thanks

That depends on a lot of factors..ultimately its what the car responds too better..case in point..my car hates water mixed with the alcohol...with its current state of tune..doesnt mean I cant get a water mix to work with it.

Use your EGT and watch for detonation..get it as close to 12.5 without detonating..without a knock sensor..good luck...spikes in the EGT will usually be detonation..

May try staright denatured and see how the car responds with a little less fuel pressure..since denatured burns..
