^^ I disagree, I ran 30psi on a 35r with a CONSERVATIVE tune on a stock longblock 4g63 making in excess of 500awtq for four HARD years running 100% methanol with a DIY kit I made. Compression/leakdown was on par with OE specs and I had the most fun I've ever had with that car -no issues with corrosion whatsoever. So long as you spray an even distribution and allow for enough space to fully atomize the meth with enough pump pressure, I see no downsides outside of making sure the system works properly.
