Pre and Post M90 setup need help

[markbudgen]

hello,

I have been running a m90 pre and post SC 50:50 methanol/water injection system on my tpc'd 993 for about a year. I use the preSC w/a injection just to improve efficiency of the SC. Both switch on independently. Before that i ran it just post the m90 for a couple of years. I have no intercooler and have run 8-9 psi at red line for about 40k miles. I would suggest that running w/a ahead of the intercooler won't give you the most from your system. I ended up replacing the intercooler that I had on there originally with w/a injection.

regards, Mark.
