PROGRESSION OF MY DC-5...

Cliff Notes: Purchased 2006, supercharged 2012, k24a2 swapped 2014, meth injected 2016. My car was last dyno tuned at 268whp/213wtq at 5psi at 7600rpm in 2015.

As of 2017, I started to learn how to tune after installing a smaller boost pulley and a prototype mercracing inlet. Based on the pulley swap, new inlet, and introduction of water methanol injection, preliminary results are below:


Est. power is 283whp/230wtq at 9psi with no meth. With meth, est. power is 301whp/231wtq at 9psi. Also note, the second half of the graph plots AFR (bold lines) and IGN (dotted lines).

2018 Update: completed self tuning earlier this year. Estimate power is 304whp/237wtq at 8.5psi with water methanol injection (single port 1000cc/min). Current bay setup as follows:

UPDATE: Got tuned back a couple month back. Car made 268whp / 213 wtq on 5 PSI. at 7600rpm.

Backstory: I did not realize that my crank pulley was swapped from the k24a2 (6.125") to the K20a2 (5.80") until the week before my tune. If I had the k24 crank pulley on, I would have made around 7-8 psi with the 3.2" boost pulley and make 290+ whp.

Other than that, the car has been driving great. I was able to source my k24a2 crank pulley back and will install this summer with EPS.

Here is how the car currently sits:


I'm getting my A-Spec front lip, A-Spec rear lip, ITR side skirts, and front bumper resprayed soon and then a proper shoot

No real updates at this time. Just been driving and enjoying it. No issues with fitting the JRSC onto the K24. The only problem I have is hood clearance with the p/s pump. Going EPS is the best solution, but I haven't pulled the trigger on that yet.

:fistbump: Thank you and yes, it's been a lot of work, especially with my limited time to work on it.

No new dyno numbers yet. I needed to handle some maintenance work on my beater and just got that running today.



The RSX needs new rotors, brake pads, tires and a radiator upgrade (car gets hot here in FL). Once those are sorted out, I'll swap the crank pulley and get re-tuned.

:fistbump: thanks homie. Several shops can do the swap, but my recommendation would be to talk to them personally. I was about to use a shop, but then I got lucky and met a friend that work at Honda that did the swap for me on the side.

Update: installed k24a2 CP and making 7+ psi. Also installed new tires, 235/45r17s on the A-Specs. Going to install AEM Water Methanol kit and retune over the next month or 2

Thank you Sir :bow: it's been a love/hate relationship, but I wouldn't have it any other way lol.

LSD has helped big time with traction. Prior to installation, I'd break loose and had to ease off to get traction. Not anymore. I haven't experienced much torque steer then again, I haven't beaten on my current setup like I used to with my K20.

Update: k24a2 crank pulley was installed and seeing 7-8psi. Car feel great and I can tell more power is there!

Should have a solid update by end of the month. Work and personal life has been hectic. Some recent acquisitions...

* New brake pads and rotors
* New nozzle kit and support shit for AEM AR3300 installation
* Prototype merc inlet

One of my A-SPEC wheels are bent after buying new BFGs for them. Since the tires are literally a month old, I pulled the trigger on some new wheels coming in a few weeks.

Appreciate it Sir :bow:

Awesome build. I once had a nice aftercooled supercharger kit in my possession but never got the opportunity to run it on the car, I bet it's a blast to drive.

I pieced together a nice little assembly to assist in bleeding the air out of my K24. It's super simple, relatively cheap, and makes bleeding the system a breeze. PM me if you're interested in a parts list.
Much appreciated Sir :bow: Definitely interested in the bleeding setup if you are willing to share :fistbump:

Finally got my imageshack working again, so minor pic update from the past few months

K24a2 crank pulley installed


New tires BFG. Sport Comp2s 235/45r17



AEM Water/Methanol injection kit installed (just received AEM nozzle to run the larger size)



And picked up an "OG" S/C part... Mercracing prototype inlet :run:





Once I finish the inlet install, I'll complete the W/M and retune. Ran into a little issue with one of my A-SPEC wheels being bent, so I got these





That's it for now. New Centric premium rotors should be here Monday to install with new NAPA adaptive one brake pads

Thank you, Sir. I wasn't looking for wheels, so these were an impulse buy lol. These wheel specs match my A-SPEC wheels: 17x7.5 +45

nice man!
Thank you, Sir :fistbump:
