Going Home

Just a picture I took last May @ TWS before heading back home.

Getting ready for NASA August 1 & 2 @ TWS

I managed to cross all the items off the "To Do" list, even new tires!

TrackTime Performance had a killer deal on Toyo RA-1, so I ended up ordering two set of tires. Brake pads were installed, and all the clutch and maintenance intems were replaced.

The Racepak G2X was easy to mount in the car, and I ended up with the display right in front the instrument cluster. I also installed an AMB transponder in preparation for the NASA event.


Finally, I installed the CHE transmission with fresh seals and a Peloquin 80% shim kit (aka Poor's man LSD). The shim kit basically pre-loads the differential even more, increasing the torque difference between wheels at which the differential opens up. I still have a full open differential, it just takes a bit more torque to act as such.

Kermit was finally back together on Sunday, July 18th. Started the car and there was a big oil leak coming from the rear of the oil pan. I had to remove it and use RTV sealer. It worked and I went for a test drive. My first impression was how long I stayed on each gear, thanks to (not really) the CHE box. It's good that Kermit makes over 120whp from 5K to 7K RPM.

Yesterday (July 20th), I went for a longer test drive run. Came home and jacked up Kermit to inspect for oil leaks and such. To my surprise the transmission case was moist with oil. Since the engine and tranny oil were changed, I didn't know where the yellow clear oil came from. After thinking what to do, I decided to remove the transmission to check if the oil was coming from the tranny seal, rear main crank seal or oil pan. It was the oil pan again. VW 8V engines use a ruber oil pan seal that doesn't need any sealers. Applying RTV as I did was just a band-it fix.

New parts were ordered from GermanAutoParts. They are sending a replacement windage tray for free and the full order is free shipping too!!!!! Those guys are awesome.

I was hopping to have Kermit ready for the last weekend of July for a shakedown with the PDS group at TWS, before the NASA weekend. Looks like I'll be spending that weekend working on Kermit.

In another note, I joined my friend Kevin's LeMons team. If I'm done with Kermit by Sunday, I might drive up to TWS and drive the LeMons car (Toyota Tercel) for the first time.

Dyno Visit & Back to TWS


April 24 - Dyno Day

Kermit visited the dyno to see what was the end result from the head work. After playing with the adjustable cam gear, we settled for 126whp and 129ft-lb. Not bad, specially taking into consideration that the baseline was 91whp and 110ft-lb.

May 2 & 3 with PCA at TWS

It took six months to go back to TWS, and nine months since the last time I drove the CW direction. This time was my first time with the Porsche Club of America (PCA) DE organization. It was a bit different for sure, specially because I was put in the blue group. They are more strict on safety than any other organization I have attended, with higher standards of instructing for advanced drivers.

First time out I got too excited because I finally used 5th gear on the main straght!!!! So excited that I forgot to brake for turn 15 and spun off track. It wasn't really bad, but my instructor got a bit scared for sure. The following sessions were much better and I was promoted to the yellow group by the end of Saturday. Sunday was pretty relaxed, it rained during the morning so I had to switch tires.

It was pretty interesting passing Porsches, specially that 997 Turbo in the blue group.

May 31 with PDS at TWS

Now back to the traditional CCW direction with PDS and one day only. I struggled the whole day with the Yokohama tires. They were done, there was still thread left on them, but I think they had too many heat cycles. They became very unpredictable: sometimes the car was pushing, sometimes it was oversteering.

I spent the third session of the day playing my friends Andy and AC and their Miatas. I was having soo much fun until the tranny decided not to downshift into third anymore (upshifting was OK). No grinding noises, just resistance. I packed up and headed home.

After removing the transmission I found a strap missing from the pressure plate. Now I know that this has been a common problem with the OEM Sach units since they went from double to single strap design. I tried selecting gear on the tranny and it seemed to be OK. I will be installing the original CHE because the AGB developed a very small leak from the passenger's side output flange. The new pressure plate is a Bildon Motorsport unit that is race rated and has reinforced straps.



In another note, I bought a Racepak G2X GPS Data Logger. Now I can verify that I suck at driving :)

Projects before I head back to TWS with NASA August 1 & 2:

- Replace water-to-oil cooler o-ring (preventive maintenance)
- Install VW Motorsport windage tray
- Replace rear main engine seal (preventive maintenance)
- Install new Bildon HD pressure plate and CHE tranny
- Install Racepak G2X logger
- Install Hawk HT-10 front pads
- Convince the wife to let me buy new r-comp tires

During the NASA event I will be applying for the Time Trial license, that's going to be my first step towards the racing license. I'm taking baby steps :)

Adding Another Track H2R


The plan for March 21-22 didn't go well. While installing the new cam and adjustable cam gear, I made a mistake and timed the engine incorrectly. As you could imagine, Kermit's engine didn't like that. After pulling the head, the damaged was reduced to bent exhaust valves. This allowed me to do the head work I was planning on doing anyway.

On April 5 Kermit and I visited Harris Hill Road (H2R) with the S2000 Club of America. San Marco's premium track is a 1.8-mile, 11-turn asphalt road course. The course is 36-feet wide with over 150 feet of elevation changes and a challenging mix of on and off-camber turns, including the 80-foot rise and drop of Santa Rita (Turn 4, named after the patron saint of the impossible task).

The day started windy, but the sunshine stayed with us for the whole day. The organizer put me in the Red run group, a welcome surprise since it allowed me to take passengers for a ride. This was my wife's first ride in Kermit.

H2R Session 4 - S2K Days from Edison Rincon on Vimeo.


H2R was also the first time for Kermit after some engine upgrades. Here is a list:

- Head milled 0.040"
- 3-angle valve job (stock valves)
- TechtonicsTuning tapered valve guides
- Autotech HD valve springs
- Autotech Ti retainers
- Lightweight cam followers
- 276° TechtonicsTuning mild race cam
- TechtonicsTuning adjustable cam gear
- OBX 4-2-1 exhaust header

The engine now pulls all the way to 7K RPM, when before you could feel it running out of breath after 5.5K RPM. I did notice higher oil temperatures with the increased red line and compression. I'll have to install an oil cooler to solve this problem before ambient temperatures reach 90°F +.

H2R was a handful track. There are no straights per se, so you are always working on the next turn. Track surface was a bit bumpy on some corners, but nothing to really worry about. Run offs looked smooth and gentle to the car.

I found myself getting tired sooner and making mistakes towards the end of the sessions. I was very competitive because of my friends S2000, which equated to a not so smooth driving. I need to go back and work on couple of turns applying the "smooth in, fast out" principle.

At the end of the day I had tons of fun and found another track that suits Kermit very well.

I miss TWS and Kermit hasn't been there since the transmission and engine upgrade. The plan is to go back in May 2-3 with the LSR Porsche Club.

New Tracks for Kermit


Dec 6 & 7 with TDE at MSR Cresson

Kermit made it all the way up to Dallas for weekend fun at MSR Cresson 1.7 miles CW course. I was still running the 020 CHE transmission because the AGB developed an oil leak after installation. I failed to inspect the output shaft seals, which were actually missing. A new SACHS clutch was installed along with a Eurospec lightweight flywheel and GruvenParts lightweight crank pulley.

Saturday started pretty cold, I was using the Falken Azenis RT-615 tires to learn the track. The first time out I was all over the place. At that point I realized MSRC was not going to be as easy as I thought. MSRC is a very challenging track with off-camber and blind turns. Since it was my first time at MSRC, TDE assigned me an instructor. I went for a spin with him during the instructor's session. I then realized I had a lot of work to do.

Next session out went better, but I was still off the pace. No big deal, just kept learning the track. Session three after lunch didn't go so well, partially because I decided to run the brand new Hankook Z214 R-comps. I didn't realize that it was going to take a full session just to scrub the tires. I spun coming out of the paddock, very embarrassing. Then I started to have an intermittent spongy brake pedal. I finished the session and proceeded to check the brakes. Front rotors were done, luckily I had a brand new set with me. Replaced the rotors and bled the brakes. Pedal was firm.

Fourth session and last one for Saturday. I was getting faster each lap until the brake padel went to the floor. The master cylinder failed :(, I was done for the weekend since I didn't feel like replacing it at the track.

MSR Cresson, we'll meet again ..........




Jan 31 & Feb 1 with NASA at MSR Houston

I took the opportunity to visit MSRH 2.3 CCW course with NASA, since they also offer a DE group. All the previous problems were fixed, plus some minor improvements like the 020 AGB short ratio transmission and ram air intake. I was so looking forward for a trouble free weekend.

Again, I was using the Falken Azenis for the first two session on Saturday. MSRH was turning out to be an easier track to learn, and more suited for Kermit than TWS. I was having a great time. In the afternoon I switched to the Hankook r-comps and I was flying. I was moved to HPDE4 by the end of the day.

Sunday was a mix of rain and sun. The very last session was an extremely fun one. I spent about three laps switching positions with my friend Alex and his Lotus Elise. I was also playing with an Acura Integra driven by one of the instructors. I made the mistake of pushing too hard trying to catch up and spun big time at the Bus Stop. Kermit escaped unharmed. I wish my new HD camera hadn't run out of batteries.

Next track event is on March 21 & 22 with TDE. I managed to convince a couple friends of mine from the European car group to have some fun with me at the track.

I have new stickers now :)

Three Track Weekends After the Rollcage

It has been a while since the last update. Three weekends at the track so far .....

October 4 & 5 with TDE at TWS

Great weekend, I was getting used to the new suspension and all the new equipment added to the car. I was able to push the car more than before. Everything was going well until the first session Sunday afternoon. As I soon as I left the paddock, the hood flew up open. I have no idea how it happened. I have couple of videos of the incident:



The hood was replaced with a red one. Kermit looked like watermelon, or something that Santa would drive. My friend Chris covered the hood with vinyl. It came out great !!!!! (notice the hood pins).


November 9 with MSC at TWS

Fantastic day at the track. It was my first time on R-Comp tires (Yokohama Advan A048). What a difference the tires make :o. I was passing people left and right. I have a video for the weekend:




November 15 with TDE at TWS

This weekend didn't go so well. First session out was very cold and I had no grip, terrible session. Second session went better after I changed the rear sway bar setting (full soft) and lower the rear tires pressure. The car behaved much better, but the clutch decided to start slipping. After inspecting the car, we found an engine oil leak that ended up in the clutch.

The engine oil leak was fixed, the problem was a bad intermediate shaft seal. New seal, crankshaft seal and timing belt were done. Now I have to replace the clutch. I'll take the opportunity the try a 020 AGB transmission with close ratio gears. Hopefully it will help increasing my top speed.



Next time out is December 6 & 7 at MSR Cresson with TDE.

PS: I forgot to mention that the white MK5 GTI was traded in for a Chevy Avalanche. I'm now trailering the car to the track.

Last Project Before Hitting the Track

Tonight I just finished my last two projects: camera mount and strapping the passenger :)
