*******UPDATE May 7 2014
After 2 years of running flawlessly at ~8.5 psi I decided to upgrade to a smaller 3.8" ASP Pulley for the Vortech V3. I was expecting 11-12 psi but only saw 10 psi in the datalogs, this is due to the lower redline of the AP2 and the fact that I have a header and exhaust. So take note, if you want to see 12 psi with an AP2 make sure to go with at least a 3.5" pulley on the AP2. Though you'll be right on the rpm limit for that blower.

Only changes to the car over the 2 years were a T1R Dual Sparrow exhaust. Really didn't see any gains from it but Im sure its helping relieve a little back pressure on the engine.

Tuning was very quick, did the retune via e tune with Evans Tuning again. Great support.

Dyno is a Dynojet, same one used as before: The Dyno software was upgraded at the shop and for whatever reason, its reading around 8 hp/tq less. When I loaded the original runs from 2 years ago instead on showing them at 371 and 376 rwhp they were down to 363rwhp. Also torque was down about the same amount. With the new 3.8" pulley results were 383rwhp and 242rwtq. That is a 20 hp and 14 tq gain at the wheels with the extra 1.5 psi.

Blue is 8.5psi stock exhaust
Red is 10 psi T1r exhaust
Green is same as red but hotter

The car feels much stronger for only having 20 hp more. The extra torque really helps. Super smooth and streetable, factory like, just much faster.

Future plans is to maybe get springs and retainers and rev to 9krpms to make that extra 1.5 psi more boost. Anybody know if there is any cams out there that really improve on a supercharger setup? With dyno results?

Ive been debating for a whole year wether or not to go with forced induction on my 2006 S2000. My previous project was a 2001 IS300 with 400rwhp first built by Lance (Toyomoto) and then upgraded and tuned by me to 500rwhp. Spent 7 years with basically no issues and sold it still on stock internals. Great car but wanted something to enjoy more as a track day car so I got the S2000. Ive spent the last year having fun on track days and slaloms where the 250hp was more than enough for me but always found it slow when it came to daily driving. For me the S2000 is not a drag car and never thought of getting huge hp out of it because I would like it to be reliable and have good drivability, also I still want to take it to the slaloms and track days. Ive always preferred turbos over superchargers but this time, for the type of use which is track days and minor road sprints, I believe supercharger was the way to go.

Im doing an eTune with Evans tuning, only been able to do one or two WOT on 3rd gear. The car feels as expected, not a huge burst of torque and speed like a Turbocharger, but a nice gradual pull from 5-8k rpms. Hopefully I want to get 108-110mph trap speeds with this setup. The fuel in my country is pretty low octane so Im using a toluene mix with fuel and water/meth injection to help out on octane and protect the engine, not to raise the ignition or try to get more hp out of it.

Anybody with a 4" Vortech pulley know if 9psi is right for an AP2? Thats the most Im getting during the hot humid day, still havent tried at night. I thought that with the 4" I would be closer to 12psi. As soon as I take the car to the dyno ill post results, most likely below average because of the humidity here. Im also checking IAT's and they seem to be good, around 95 degrees so the heat exchanger and water/meth are really helping out.

Anyways, really happy with the car. The install and info wouldn't have been so easy if it wasn't for all the homework I did here at S2ki. Thanks!

Impressed and happy with the results. Tuning is still not finished, need to get the A/F down to 11.5's. All done by Evans Tuning via Etune. Water/Meth injection is allowing to run high ignition and make this power at only 8.5psi. Disregard the red line, the rpm signal got interrupted.

 

Nice looking set up you have there..

Where does the heat exchanger piping go?!

 

There are 2 fittings for the water hose on the drive side.

To op: Just curious why you went with water/meth @ 9psi.

 

He said he was using it to boost octane since his country has lower octane level fuel

 

We have at best 91 octanes here, more probably 89. Thats the main reason for the water/meth. If 9psi doesnt give me any problems I may go up to the 3.5 pulley to get 11 psi.

 

Oh okay, thanks!! I never realized it was a air/water heat exchanger, I didn't know they made them that way.. I always thought they were all like the aftercoolers that come with those sc kits..

Edit****

I thought the only part of the aftercooler was the part that's visible in the engine bay, I didn't know it had a core infront of the car to get air..

 

Sorry for not reading everything Have fun with it!

 

Looking good, nice to see a clean setup done right!

Keep us up to date on the reliability but I doubt we will hear anything but good news.

Was the etune easy to do?
