Ok, so I have another question...
If I use a meth/water injection kit... do I still need to retard the timing under boost?
You would not need to retard the timing as much as w/running pump gas.
I can say w/guys & there Syclone & Typhoons,running meth injection,normally timing is @ 17 ish total,but when injecting straight meth they turn the total timing up to 24 ish.
But remember,the Syclone stock runs 14-15 psi stock boost pressure.
Guys that run 20-26 psi range are running anywhere from 20-24 degrees of total timing,every engine is different though.
I think Tlowe says he runs about 28 degrees total timing,but he is only running 12 psi of boost pressure,(correct me if I'm incorrect Tom)
Guys running w/out meth see intake air temps pretty high running say 22 psi up to 200 degree F,then when they inject straight meth they see temps in the range of 50-100 F,,,these temps are just general info,not totally 100% accurate because I am going from memory off the top of my head,,but you get the general idea.
Methanol makes a huge difference in power & allows you to crank up the boost as you could be able to when using race gas like C16,but you are running pump gas 91-93 octane.
Guys w/there Buick GNs,& w/there Syclones & Typhoons have used water/meth
,but they will all tell you the same,,,straight methanol injection will make more power than it does w/water/meth injection.
So, in genral,yes, you will not run as much total timing as you would normally aspirated.
Hopes this helps in some way.
