I've seen different SC/TT setups for the 350/370Z on this forum now and have noticed some use a single Intercooler for both -chargers, and some use a seperate intercooler for each side. My questions are:

1. Does this even matter using a seperate Intercooler for each side vs. a single Intercooler?

2. If it does matter, which is better, 1 big intercooler feeding both sides, or 1 seperate one for each SC/TC?

This might offer some insight:

S-Max also produces an intercooler similar to the one with the coils in the front. The S-Max IC have the coils integrated in them.

^^ Wow!!....a buddy of mine showed me that same unit. looks like it would be an interesting idea. FWIW: Third hand info is that it didn't work so well...but to be fair, that was a G35 and set-up is unknown.

not sure if intake charge temps is the same as Intake Air Temps but when i was spraying meth/water in my supercharged cobalt. My IAT2 dropped ALOT by using meth/water injection. I was seeing 18* timing with 140* IAT2 temps, when i put meth/water on i was able to raise the timing to 22* and IAT2 dropped to 130~. Then once i got the TVS Supercharger and took the M62 off and also changed my mix to 75/25 (meth/water) put a bigger nozzle on (7gph). I raised my timing to 25* (max timing the LSJ Ecotech can produce power) and only seen 130~ after 4 runs on the 1/4. So in other words, it does both raise octane level and cool IAT's

Yeah someone corrected me a while ago, the mix is cooler.

This might be unrelated, but is nos even legal? And if it is, is it legal in new jersey?

Snakes, see post #22...

Hell no NOS is not legal in any state that I know of. Even here in WI you can get a huge fine for having the bottle connected to the lines while driving, even if it is empty. I beleive you can transport in most states but have the bottle attached to the lines is a NO-NO.

Ive heard of turbo guys using the water/meth to help keep intake temps down and not even advance timing. It was a way of helping the stock IC not get as heat soaked and lose power. They would just let the ECU do it and this way if they ran out of the mix they wouldnt have to worry about the timing being off as the ECU would adjust it again. Kinda like a different type of IC system that they could get some bennifits out of everyday driving and then tune it for track time quickly and then back again.
