THMotorsports Redline Time Attack Build-Up, Progress, and Racing thread.
 

Hey guys.

We have been supporting the Mazda community for a while now and try to help out with those pursuing their passion in racing, car modification, and simply pure vehicular enjoyment. We too are passionate about racing and building cars and here is one of our cars that we have been making some progress on.

Not sure how many people on here follow Red Line Time attack but we have been busy for the last year putting together a nice competitive car. We ran Sebring a 2 moths ago and experienced a ton of problems, and slowly worked them out. After that we went to a few local-to-Chicago track days, with mixed, but better and better results.


We took the STi to Autobahn Country Club Race track this weekend for a high speed autoX. Basically standing start HOT lap, and a fly by finish at the finish line. Pretty fun...great competition.


Well.....we had some issues. After tooling around with the ECU and figuring out why its not regulating boost correctly a light was shined down on us through the gloomy clouds.

We ran the waste-gate with the stock spring set at 1.2 BAR, instead of using the faulty boost controller which was supposed to be set @ 1.8 BAR. Instead the boost controller would randomly let the turbo go as far as it can. 2.2 BAR+ (not fun/good)

With a nice steady boost delivery we focused more on the driving. We were able to knock out lap times that were basically just as fast, if not faster faster than our competition did at Red Line Time Attack at the same track 2 months ago. We should be very competitive in the up coming season if we keep this up.

Overall a great learning experience and yet another track day to further prepare us for Redline Time Attack next season. We want this car to be more than bullet proof.

BTW our Ghetto lip is a new test in progress. ha ha...it turned out pretty good with lots of grip. We basically lowered it by about 3 inches to see how it would react. It did very well and we will make a nice non duct tape version of it.

Also front overfenders were finally painted and rear overfenders will be going on as well. Updates soon.



Thanks for looking...videos coming soon.

BTW check out THM Racing for some of the past event details including our build thread.

meh 50/50 rule:P if you can't tell its ghetto at speed, then its not ghetto.

nice stuff ! :)

its Ghetto functional/fabolous...ha ha.


funny, people on the track said they are going to try to create something the same.



Thanks guys!!

I will post up more updates as the come...we have been slaving on this car. Its taking me away form my 20B RX8 project but all in time.



I will post up something from 2 weeks ago too. GOt a sweet video of the car in action.

nice cant wait to see more updates

Fo sho....

Forgot to add that we were just at Blackhawks Farms Raceway about 2 weeks ago, mustered off a 1'21" 198, which was good enough for 4th in MWCSCC.



Heres a little writeup I did.

This past weekend the THM crew ventured out to Blackhawk Farms Raceway with the Salt Creek Sports Car Club and the Midwestern Council of Sports Car Clubs for a high speed auto cross. Generally, when the average racer hears “auto cross” they associate it with racing around cones in a parking lot. Truth be told, high speed auto crosses are more similar to full fledged track day. You are timed for one full lap, beginning from a dead stop; pretty cool if you ask me. The competition was rather fierce, as was the weather.

Upon arrival at Blackhawk Farms Raceway in South Beloit, Il, the team encountered a generous amount of rain. This put quite a damper on all the morning sessions, luckily enough, they were only practice. A few warm up laps showed the true colors of the Toyo R888 tires in wet conditions. While traction was ample in the straights, it suffered severely in the turns. By the time the afternoon rolled around, the track had completely dried creating more favorable conditions for all competitors.

Many of the issues plaguing the crew at the last track day were ironed out including the ECU problems and the mushy brake pedal. It seemed as though the car was finally near 100%! To this day, the drivers of the car still comment on how crisp the handling is, much thanks to the Stance 3 Way Coilovers and the Toyo R888’s. As well, the car was only running the pump gas map, though still proved to be a worthy competitor on the track. The driver, Andrei Tsaran, commented that “the car could use a bit more power, as we have not found the limits yet. Aero also needs to be developed, but the new diffuser seems to be doing a great job in the rear.”

As with any race car, and fine wine, it only gets better over time. It seems as though we have a winning combination, overall, and just needs to be dialed in to be in the top of the class. Out of the 108 entrants, the THMotorsports came home with 4th place. A few more trips to the track, and some power tweaks, we should see this car skyrocket to the top. Ill let the pictures and video do the rest of the talking…

I am working on a similar setup on my RX8 for the down-force...it will be mad sick.

Our uber busy engine bay shot...and you guys think our engine bays are hard to work on. changing spark plugs is suck a pain!!!



Attachment 252449

now thats ta tight fit, no pun intended

ha ha...dude its a pain in the ass to get anything done on it. I rather work on the Renesis... ha ha.

And vacuum leaks are a nightmare...and we check for them before, during and after any event....lol.


We are taking the STi out to a nice high speed autoX in the Chicago region @ Route 66 in Joliet if anyone is around there hit us up. We are going to go play with some new suspension settings.

shits a beast

Sorry Adam for quoting this older post but i just noticed it.
A dear friend of mine is running a kognition design wing on his rx8 and wrote something about the install here. Sorry again for the threadjack as well, let me know if there's anything you need\want to know about what we tested this far.
These wings are AMAZING to say the least.

G

yup that she is...lots of work. the further we develop her the better she gets!

Yeah they are awesome. We did ours the same way...super solid. Going same route with my RX8 but might be looking into mounting it differently. Definitely chassis mounted.

It will be a while till you see that though...

We can wait!

that 8 looks very good with that wing...glad to see it chassis mounted instead of trunk mounted like JIC.

This thread is about your scoobie!

Damn it!!!

I hi-jacked my own thread!

For those who have missed Circuit Battles on TV...here is some nice family friendly content...Enjoy!

schedule

Some pics form last weekend at Auto Club Speedway in Fontana California. We had our STi geared up to compete in round 3 of Redline Time Attack but unfortunately we blew both head gaskets and were pushing a bout half a gallon of coolant a lap so we called it quits. Motor will be stronger and will push even more power once finished.

What's happening with your 8 and the 3 rotor engine?

When i have time i put in some work to it. I am in the process of rebuilding both my 13B and the 20B. Lots of baby steps... I will post up some pics of the motors apart soon.

We had a good deal of new issues at Willow Springs. Most were overcomed with hard work and dedication. Racing and development is a fun battle!!!

Issue 1. Low than zero oil pressure. Oil pump went down due to bad machining/shimming than damaged the piston inside.

Issue 2. no fuel pressure. One of the walbros in the tank died. We replaced it.

Issue 3. Knocking, hesitation. It was 105-110 degrees outside and track temps @ 165 degrees. Decreased the timing a tad and changed the spark plugs we were good to go.

Issue 4. Electrical failure. Car died while we had 6 car lengths over the K&N G35.



STi is in Nebraska right now. Cruising back to Chicago and prepping it up for all the local events, including but not limited to the GTA @ Autobahn later this year.

More updates soon.
