Hello all, Showing some progress made on my 2006 AP2 here in NM, USA. Brand new with 33k Miles.  Untitled by Ali Al-Daouk, on Flickr I autoX'd the car for the first, and last time. I hated the long wait for seat time. But it was a really good way to feel for the car.  Untitled by Ali Al-Daouk, on Flickr  Untitled by Ali Al-Daouk, on Flickr STOCK Lap Time: 1:38  14936809481_a1107213dd_k by Ali Al-Daouk, on Flickr At this point, i've taken the S out to our local race track and felt a bit of understeer, a lack of dive was occurring and I could not get the car to turn in as quickly at speed. I did research and wanted to keep the car as stock looking for now as I could and got a CR lip, the change was noticeable. And dropped a half second around the course consistently to be around 1:37.5  DSC08931 by Ali Al-Daouk, on Flickr The 250 Treadwear tires that came with the car were decent. However, we all know tires make the car run well, a set of 17x9 Enkei RPF1s and 255/40/17 Square setup with RE11As were in order. This setup dropped my lap times a full second consistently to 1:36-1:36.5  DSC09388 by Ali Al-Daouk, on Flickr  DSC09397 by Ali Al-Daouk, on Flickr |

I felt some oversteer with the new setup as I was getting a little more balsy and taking turns with more speed. I did more research on the aero for the car and bought a small diffuser, not much quicker round, but it did keep the rear end from stepping out so much.  DSC09409 by Ali Al-Daouk, on Flickr  DSC09471 by Ali Al-Daouk, on Flickr  DSC09477 by Ali Al-Daouk, on Flickr Did a little more experimenting with the aero setup and bought a front splitter, it did help dive the car into corners, however, at speed I found it was just short of the optimal length for the S2000 and was generating drag, slowing me down on the straights.

At this point, I finally invested in some power adders, an intake, exhaust, test pipe were added. I had it tuned and dyno'd at 210 WHP at 5500FT in elevation and 136ftlbs. VTEC was lowered to 4500RPM and i saw my lap times drop by 2 full seconds to 1:34. I also felt brake fade, and invested in some slotted rotors and RBF600 which resulted in a half second off, braking later into corners. 1:33.5.

 11062697_1015244721838898_1545688722276065804_n by Ali Al-Daouk, on Flickr I did some MORE experimenting with the aero and ditched the drag producing splitter and bought a CR wing to complement the front CR lip and rear diffuser. The wing bumped my speed on the last corner from 66MPH to 73MPH, resulting in another second lost. 1:32, this setup ran me well, and I decided it might be time for an alignment. First go around was 2 degrees camber up front, 2.5 rear, zero toe; another second lost; 1:31.  DSC02851-2 by Ali Al-Daouk, on Flickr Then I really started to get crazy, the tail end would push ad I decided to get more rear downforce to stick it in the corners at higher speed. I invested in a Spoon rep Diffuser, this alone was an amazing upgrade. I dropped a full second yet again, 1:30 dead. Until I got the bright idea to get rid of the 17x9 wheels for 18x8.5 on a 255, my lap times increased a second and a half, and changed my alignment. Advvan RS wheels 18x8.5, bridgestone RE71-R 255/35/18  DSC04135 by Ali Al-Daouk, on Flickr  _20160810_101300 by Ali Al-Daouk, on Flickr  DSC00062.jpg by Ali Al-Daouk, on Flickr DSC00062.jpg by Ali Al-Daouk, on Flickr I hated this setup so much, heavy, and not as much grip. So I decided to go a different route. |

The ASM replica bumper, with active brake ducts. Enkei TS9 17x9 Wheels, RE71R tires. Switched up the power adders, ditched the duel exhaust for a single, dropping 30lbs, also going from a 70mm to a 73mm, its louder, but more powerful. Ditched the old CAI, for a K&N FIPK (Known to make power on the S), bought a cooling plate that direct feeds air into the intake via a custom ram air setup. And finally added a BC 330mm BBK. The result, 1:27 consistant lap times, which is the record at our local track for non-racecars (IE; trailered cars/non street legal.)

Which will be 2 seconds quicker than the fastest lap around our track in a racecar. (350WHP Porsche 944) I really want 500WHP on the car. F/I for sure. Over fenders rear and wider up front, with a 17x10 wheel and 265s square Roll cage drive the piss out of it. Here are some videos. youtu.be/RwWwOM8ee_8youtu.be/AD5aWXpmA5gyoutu.be/CRaHpivvLgcyoutu.be/eUJg9c89RuA |

Nice motor, sounds like you have played with the set up on the car quite a lot to make gains, look forward to seeing where you go with it

Amazing how good these cars look especially when you remember how old the basic design is these days!! Has aged VERY well, and that engine is still pretty much top of the N/A tree 😎
