Hey J.R, just checked out your pics.
Looks like you are dual passing the I/C? I would be concerned about the pressure drop if you are. The core looks around 3" thick, and I think the dual pass might be a little restrictive. I reckon you would like the setup I am going to use. Unfortunately I only have a cardboard box for an I/C at the moment (trying to find a cheaper shipping price from the US for my core, as the shipping is almost as expensive as the core $200 USD!!!).
When I get the core I will take some pics for you. I'm going to go water/air, which I don't necessarily like, but I think is the best setup for the NSX.
On the subject of water/air ,I am going to relocate the A/C receiver/dryer from infront of the radiator to behind. this will allow me to neatly install a fairly large rad for the intercooler. I am also going to control the intercooler pump speed with the Motec, using the fan control "thingy" from an EVO9. This will give me fully proportional pump speed based on boost pressure and air intake temp. Saves having the pump going flat out all the time.
Whilst we are on the topic of the Motec (well, I am anyway :biggrin: ) I am also going to have a valve in my exhaust system. Actually two, one on each muffler. I am going to have a 2.5" tube inside the muffler, with a butterfly inside. When closed, the exhaust will have to travel between the perforated 3" inner tube of the muffler, and the 2.5" tube. This should reduce the noise significantly and also limit the power capability. I run a bung in the back of my Civics muffler on the street, and find that the restriction makes it really nice to drive in first and second gear. Much easier to control the power delivery. On the NSX, I am going to control the exhaust valve with the motec. I am planning on using a table with throttle position and slip percentage as the two axes. Basically, below a certain throttle position, the valve will always be closed. At full throttle, the valve will open. Then, if wheelspin is detected, the valve will close proportionally with the amount of spin. It will work in a similar fashion to a standard traction control system.
Any way, enough rambling. I really should be working on the car........
