With the final race weekend of the MotoIQ Pacific Tuner Car Championship presented by Motul coming up quickly in less than 2 weeks, we are due for a much needed recap and what the teams have been busy working on in preperation for the final round of the season. Let's take a closer look at the last race weekend which ultimately shaped the close championship points chase.
In installment 4 of the Polystrand GT-Lite Project, we made our deadline and had the car ready for a couple of trade shows. Granted, we had some issues that we needed to take care of – we checked the rulebook, and it turns out the wheelbase was a bit too long – and the rear of the unibody was found to have been pushed over to the left about an inch from an on-track incident in the CRX’s storied past. In addition, since we made so many changes, the rear portion of the cage was no longer tied in to anything structural.
In previous installments of our Project Mustang we had installed most of the common bolt ons for our 5 liter Coyote engine. We had gotten a pretty decent boost in power but we had noted that our power would really fall off at higher RPM, more that what we thought a free breathing 4 valve motor should.
I’d like to get something off my chest. I am enamored with the idea of hopped up, ass kicking, rip snorting, high performance wagons. V8-powered shooting brakes, high revving hot hatches, and bi-turbo estates (for our euro readers) all seem to get my juices flowing. I can’t quite pinpoint exactly why that is, but there is just something so scandalous about an unassuming five-door giving more pedigreed performance machines a run for their money. Now, I need you to understand that I am absolutely smitten with this car, and have been for the past several years. It is, in my eyes, the perfect vehicle. So please excuse me if I become a bit over-zealous at times. Enter Project Legacy GT, it is Subaru’s mid-size performance vehicle which is equipped with the usual all-wheel drive system, 5-speed manual transmission, and a typical 2.5L turbocharged flat four engine.
The Viper is a “racecar for the street” in more ways than one; and like a racecar, it does not like to sit in stop and go traffic and can run hot and overheat without proper airflow on a hot summer day. To combat this we upgraded the radiator fan on our 1997 Viper GTS with the higher flowing, larger fan from the 1998-2002 cars. In addition, we safeguarded the potentially flawed wiring and relay box by running standalone relays with dedicated power and ground wires. To further extend the life of the relays we used a trick pair of “NOsparc®” spark suppressors in the harness.
Choosing a tire is one of the most important decisions that anyone will make for their car. Since our M3 is a daily driver in Florida, wet-weather performance is very important along with excellent dry grip and stability for spirited driving, which is a prerequisite for an M3. To give our car a more sporty appearance, we turn to VMR Wheels for a set of competition inspired 19” V703 wheels to replace our standard 19” wheels wrapped in Continental’s ExtremeContact DW tire. We then head to Palm Beach International Raceway to log some laps to see how the new package performs.

I was honestly very intrigued when I read the article here on MotoIQ about the development of the Fluidampr Crankshaft Damper. Seeing the dyno charts showing improvement in power and torque on a Stock FR-S and having a pulley/damper that should reduce harmonic engine stress on the engine would be the hot ticket. It really almost looks too good to be true.
Keeping cool is the key to a reliable track car. To add more coolness, I attacked the problem using two methods: adding better heat exchangers and adding airflow. I’ve shown you what the new fluid temperatures have been after the modifications, but what about the actual air temperatures? I added some thermocouples to find out.
Our Project VA WRX does not have the trick Brembo brakes that come standard on its big brother the STI. It does however have brakes that would have been considered to be great just a few short years ago. Although the front and rear calipers appear to be pedestrian sliding calipers with two pistons on the front and a single piston for the rear brakes, the rotors are big. The front rotors measure in at 316mm in diameter and 28mm thick while the rear rotors are 288mm in diameter and 8.5mm thick. The pads are also large for OEM type calipers.
In our last edition of Project 350Z we started to assemble our VQ35DE and got the bottom end pretty much done. Now we finish off our engine and take it to Church Automotive Testing to get our factory ECU tuned using the UpRev Osiris tuning package.
