After a crazy few weeks of work after the decision was made to convert our Spec Z to a ST3/TT3 car, we were able to make it out to the first NASA event of the season at Sonoma Raceway.

The car went through a big conversion, along with some basic weight savings work that was not allowed in Spec Z, the most notable changes were:

- Jim Wolf Technology C2 cams and springs
- PPE Engineering Long Tube Headers
- Jim Wolf Technology Intake
- SPL Parts full spherical conversion and all adjustable titanium arms
- JRZ RS Pro remote reservoir shocks and Hypercoil Springs
- Hoosier R7's
- Aeromotions wing

We were able to make 295 WHP up from 265, and the car weighed in at about 3040 w/driver. We still need to do a little work to get to about 310 HP, and get the car down to 2900 w/ driver to be really competitive in ST3.

As it was we were within about second of the leading e46 M3 in the class, we turned a 1:48.3. Enjoy the video!

 

Awesome! What swayed you from Spec Z?, or are you building another car?

 

The main two reasons are competition and the more open ruleset. Spec Z isn't really catching on out here in CA, and as I believe in the potential of the series, I got tires of racing myself .

ST3 also allows me to showcase a little more what I can do as a car builder given the open ruleset.

 

Awesome, thanks for posting!!

Haven't run at Sears since the 'early '80s (well before the re-config of T8+)! Nice to relive, if only virtually. Oddly, I still get that shuddering feeling of impending doom coming out of the esses (in your vid).... right about onto the spot I went off course at T10.

Backwards. Ooops.

 

Yeah turn 8, 8a, 9, and 10 aren't for the faint of heart haha. Scares me every time.

 

Still a long way to go to run down Mayfield's winning TT3 time in the long run....just keep chipping away at it.

 

Watching you run definitely is making me think twice against going FI. Looks like a blast.

 

In for vid after work!

 

What time did he run? What car is that?

 

Keep the motor simple and affordable, and spend your money on track time! That is my advice to almost anyone getting into tracking unless they have a very large cash reserve. If you want to spend extra money spend it on proper suspension and a little aero. You'll have way more fun going fast in the turns rather than just mashing the gas down the straight away .

 

E36 that won West Nats in TT3...

...He ran a 1:41.3.

 

I think we need a bigger splitter .

We are not building the car for outright speed only, the main goal for the car is ST3 and E0, and the 25 Hours of T Hill. We sacrifice speed for durability and weight to be sure. With some more time on the car maybe we can get close, but that is a ripping fast time for a TT3 car.

 

This is how we loose over 100 lbs to try to catch the M3's. Seibon Dry Carbon!

 

Whoa...too rich for my blood.
