Anyone done methanol (50/50) on a turbo system? The following high-quality diagram shows my current setup's air flow down the charge pipe: IC -> BOV -> IAT -> TB Around the net, many people say the ideal injector placement would be between IAT and TB, but in this case, they're so close...

Had Coz replace my worn out clutch on my 450-550whp NSX with a wonderful Exedy cerametallic twin clutch. Very professional, ultra-clean install, fun guy to chat with, took time to show me the ins and outs, things to look out for, keep an eye on, etc. Just a great transaction all around. To...

I'm thinking of doing an oil analysis on my next change. If you've had this done before, can you tell me: Who did the test, which tests you had done, and if you felt it was worthwhile. Maybe cost too, if you recall.

Which do most kits do or recommend? I'm reading vent-to-atmosphere BOVs can cause poor idle, rough running.

Makes a chittering sound after startup. I always warm up the car before taking off, sound seems to subside sometime thereafter. This was recorded after the car had been completely warmed up, then sitting (turned off) for 30 mins or so.

I just got a paint thickness gauge, and am wondering what depths to expect around the car. I've got a red 91, if it matters.

Why was the bump deleted? Granted, I submitted the original post just shy of a month ago (6th), but I wanted to do the bump on the turn of the month, easier to remember. Is that why the bump was deleted? Come to think of it, I should probably time that around the middle of the month...

Aftermarket (RM Racing?) Headers from 91 NSX for sale $550 + shipping. Still trying to figure out the make from the previous owner's documents. Best guess is RM Racing, can't be sure.

Had a SOS blower+intercooler installed recently, very nice setup, recommended. Good pricing overall, especially as we ran into unexpected problems due to the car's previous configuration. Chris did a great job keeping the project moving and smoothing out the bumps. Jeff did a fantastic job...
