Finished S/Cer web pages

[Mark911]

For those interested, I finally got around to putting some text describing all the pictures in the “Forced Induction” section of my website. In reviewing my site statistics, the FI section had the most interest so I completed it first. I’ve also added several more Video files, some large and some small. Just FYI. Mark

Impressive.

I am in extreme envy of your vision, fabrication and execution. Wow!

The oil cooler gets 10/10 for package placement...somebody needs to "kit" that one up.

awsome videos!! what is that button on the shifter?

hehe " thats enough Mark" :smile:

That's my "cheater" heel-and-toe switch. I got it connected to a solenoid that pulls the cruse control cable and "blips" the throttle at my command. Works pretty good once you get the feel. Mark

Mark, is your Bio section current?

I only ask because it mentions a wife. I'm pretty sure i'd be divorced if i spent that much time in my garage working on my nsx...

btw how hard is it for an average welder to put together your version of the aftercooler? I don't have the ctsc, but i imagine a LOT of people would be interested in your aftercooler if it fits the usual ctsc..

Very nice job on the website and love the videos. Although I won't be modding my car as much as your, I hope it sounds remotely as sweet as yours does when I eventually get the CT i/sc/e/h installed.

Only weekends!

With the new square wave super duper TIG welders on the market today, just about anyone can easily weld aluminum. My welder is a vintage WWII Lincoln 300. Not much electronics but LOTS of copper (about 400 lbs).
I'm working on-and-off on an air-to-water charge cooler for the CTSC. I've got a design that works on paper but I'm not happy with the plenum sizes necessary for the S/Cer to clear the glass. I'm waiting for Ken Sampson's dyno results as he has a similar situation. I haven't heard much from Ken since he wrote about a low boost pressure condition (that's what I was worried about). Anyway, here are some pictures.

If you like the F1/superbike sound you'll need a Gruppe M exhaust. It's the only one that has that pitch. Mark

Mark,
Why doesn't anyone make an aftercooler which runs off an evaporator powered/cooled by the A/C set up the most NSX's already have?

Seems like all the elements one wants for an aftercooler are already there, way to capture energy(evaporator), way to move the enrgized medium(compressor), lines to tranfer the meduim, way to disipate the energy(condensors) aready located in a good location with plenty of air flow. All this with a medium(freon) which can carry much more energy than either water or air because it utilizes a phase change from liquid to vapor as energy is absorbed/dissipated. Should be able to make a unit that would almost fit inside the stock plenum.

Thoughts?

The Gruppe M exhaust looks like a very nice design. If you don't mind, I have several questions:

1) Would it make for more gains than the CompTech exhaust (not that the CT makes much)?

2) Since the Gruppe M exhaust appears to replace the catalytic converters, is it still street legal (CARB certified) in CA?

3) How loud is it when driving in traffic, backing out of the driveway, etc. I'd prefer to keep things relatively quiet until I want to get on it.

4) Can and/or how easy is the exhaust to set up for a later model ('05 NSX-T)?

thx...

 

[NSX-Tuner]

After doing some checking, the Gruppe M exhaust is not street legal so that rules them out for me. But damn they do sound sweet...

I think we’ve all thought about that concept at one time or another. And although I’ve never run the numbers, intuitively I’d say it’s never been done for the following reasons. The amount of heat energy in 110 degree air flowing at maybe 10 cfm is significantly less than air at 260 degrees flowing at 500 cfm plus. Bottom line, the A/C system simply doesn’t have the necessary capacity. Would it cool the IAT? Probably a bit until the refrigerant in the evaporator (liquid to gas phase change) reached such a high temp that the condenser is overwhelmed and can’t take enough energy out of the refrigerant to cause another phase change (gas back to liquid). Without the two phase changes and associated latent heat of evaporation and condensation cycles, all you have is hot gas circulating around the system wasting crank power. Now, if one were to design a system with the necessary capacity that might be another story. But the trade would need to include the power loss needed to run such a large pump, etc.
I’ve been toying with the idea of using exhaust gas energy (heat) to power one of those old style “RV” ammonia type refrigerant systems. The energy to run it would be free and the system has no moving parts. I’d use it indirectly to cool the water from an air-to-water IC. There’s just not much information available on those old refrigerators as most have been changed to the new Peltier type systems.
Good thinking, though.

Very very impressive knowledge. I think you should market that FI package, Mark.

A little off topic but this might help NSX-Tuner get the sound he is looking for. I wanted to leave my cats on also and liked the Grupp M sound. The unique sound comes from the 2-1-2 cross over so I tried this.
Don't make fun of my welds this is a prototype and I was learning :redface: .
The cross over can have other benefits like reduced cabin droning and potential power increase from scavenging on NA cars.
The sound is sweet but won't be as loud as grupp M because the cats are left on. Any good exhaust shop could do this and they could even TIG weld it.

You're right about the 2-1 combination. I think what you did is bad ass. Good job. For the track I'm gonna try removing my mufflers and simply add one of those cheap "pep boys" tuner mufflers/megaphones to save some weight. Not sure how it's going to sound and I'll need to check it out on the dyno.

Is that JB Weld? Or what tube product was it that you used? It almost looks like real metal where you joined the sections together. :wink:
