Rally GT86 - The Little Car That Could - Lots of rally video and photos!







I'd like to share with you how a Circuit Motorsports tuned Toyota GT86 race-prepped rally car performed in Peru's largest annual rally race - the Rally Caminos Del Inca 2014. This is a grueling 2,550 km rally with 5 days of racing spread out over 9 days racing on tarmac and dirt/gravel stages from sea level to over 14,000 ft. in altitude. It is one of the few Rally races of its kind left in the world -- racing city to city over long distances on a variety of surfaces anywhere from public highways to goat trails.

Lucho Alayza, a well known rally racer in Peru, is the owner/driver of this GT86 rally car. He very recently upgraded to the GT86 from a Toyota AE86 rally car as he saw much potential in the GT86.

At the end of the race, Lucho finished first in class with the nearest class competitor over an hour behind. Lucho also finished in 2cnd place overall, beating many more powerful and better funded rally cars such as the Subaru STi and Mitsubishi EVO.

We helped Lucho with some parts, and I performed a remote Dyno tune on his GT86 (results below). He decided to give the EcuTek RaceRom tuning a try instead of going with a full standalone ECU, such as a Motec or Haltech unit. The results were great, and the engine is performing flawlessly, with the car running flat-out at 142mph and 7200+ RPM for extended periods of time on the tarmac stages.

Please find below race standings, photos, videos, and tuning information about this awesome GT86 Rally car and Lucho Alayza's great success!

Enjoy!!

- Bob

Official Final Race Results: Lucho won 1st in class with over an hour lead, and placed 2cnd overall!!!




Final Race Results:

Lucho with his rally GT86 has won his class, with an overall 3rd place podium finish! Impressive!!

Lucho finished over an hour ahead of his nearest class competitor, and was only 6:41 (min:sec) behind the overall 2cnd place EVO driver.




Race day 4 standings:
Lucho and his GT86 remain 1st in class, and have maintained 2cnd overall!


Lucho anticipates the EVO only 12 min. behind to overtake him in the last stages of the Rally on Sunday, for a 3rd place overall finish, which is still amazing. The last stages are all tarmac with long straights and sweepers, and the EVO has an awesome tarmac setup and close to an extra 200whp over him.



Race day 3 standings:
Lucho and his GT86 remain 1st in class, and now 2cnd overall!





Race day 2 standings:
Lucho - GT86 is 1st in class, and 3rd overall out of 90 some competitors

Engine Setup and Tune:

Setup:
K&N Intake
Nameless Performance 4-2-1 Header with 2.5" straight pipe
TODA racing big throttle body (may be coming off)
TODA racing lightweight flywheel
TODA racing lightweight pulley kit

Running 98 RON gasoline

Redline: 7800rpm
Top Speed on flat Tarmac: 142mph (5.13 FD installed after tune)


Tuned using EcuTek RaceRom by Circuit Motorsports!





The dyno used is a Dynocom dyno.

Note: The pre-tune results were with all of the hardware installed running the factory tune.

These are the results from the initial tune. We did not have much time to get the tune in place. We also did some fine tuning later on a test rally course. We'll be fine tuning it further after this rally race is complete.



What really impressed us was the 75+ lb.-ft. torque gain in the dip around 4200 rpm. With a tune, the nameless header really shines!

That thing is astonishing. Do you know what suspension is on it? I saw the external reservoirs in the engine bay.

I'm sure it's excessively expensive, but I know there have been several people on here looking for slightly taller, long travel suspension.
