GR86 Sprintex FA24 kit -Backs up it's claim of being the Kings of Torque
The long awaited Sprintex supercharger for the FA24 GR86 and BRZ is finally ready to be released to the public. 86speed will be offering the first 10 production units to our customers all over the world. Sprintex states they are the “King’s of Torque”. We wanted to put that claim to the test, and with the help of Delicious Tuning, we can unequivocally say that Sprintex means it. Our 86speed GR86 had the first unit in the United States which we debuted at the 2023 SEMA Show in the Sprintex booth here in our backyard of Las Vegas , and the car is 100%, without a doubt, a torque monster!
For the past few months, everyone wanted to know what the numbers were. Just going to get it out of the way and tell you what they are first before we delve into more information on this kit, tune, and our findings. Also, as we know people will ask, the clutch has been holding up perfectly fine so far. There have been around 80 dyno pulls and no issues yet.
Firstly, let’s talk about the 86speed shop car and what’s done to it. It’s a 2022 GR86 with a manual transmission. As far as mods, it only has a AWE Touring catback exhaust, Delicious Tuning CAN Flex Fuel Kit, DW 700cc injectors (ethanol/flex only), and the Sprintex 210 SPS supercharger. You read that right, OEM headers, OEM joint pipe, and OEM front pipe. Just as it rolled off the assembly line at the Gunma Factory in Japan. We wanted to showcase what this car can do with stock piping, and this means great things for the 86 community in California and other states. So take this into consideration when you are trying to see what you might make with your own modifications.
*On pump gas you will not need injectors, but flex fuel or a ethanol tune, you will need injectors
Dyno is a Dyno Dynamics dyno which is setup to run in comparison mode (DynoJet Mode). The numbers you see are what you would see on any DynoJet in the United States.
91 Octane Results - On straight ACN (Arizona, California, & Nevada) 91 Octane, our car made 300 wheel horsepower and 255 wheel torque. This wasn’t a hero run on the dyno either. This is consistent numbers pull after pull. Graph below represents a stock GR86 and the Delicious Sprintex Tune
Ethanol Results - We also installed the Delicious Tuning CAN Flex Fuel Kit on our car as well as Deatshwerks 700cc injectors. Bill at Delicious Tuning wasn’t able to drain out all the 91 octane in our shop car, but with the ethanol added in we were at E65. On that blend, our car made 350 wheel horsepower and 310 wheel torque. Graph below represents the stock Sprintex tune, the 91 octane tune, and the E65 blend tune.
The torque on the car comes in low and it comes on strong. For example, on 91 octane, at 2500 rpms, the car is making 215 ft lbs of torque. By 4300 rpms, it has full torque of 255 and keeps pulling to redline. To just reiterate, this is all with OEM exhaust components except the AWE touring catback. And the only other mods on this car are the flex fuel kit and Sprintex supercharger. We went this route, to show you what the car is capable of on stock exhaust components while being emission friendly as well as being future CARB legal (for CARB states). But with great torque comes great responsibility (actually tuning challenges, but wanted to have a spider man quote//pun).
Bill at Delicious Tuning, spent a good amount of time with our car. The challenging part wasn’t the WOT (wide open throttle) tuning, but was the streetability/drivability tuning and trying to contain all that torque. Since we installed this 2 days before SEMA, and it was a prototype kit. We didn't have the luxury of time to fine tune it as we were working on major time constraints. We were probably one of the first few companies/people with a boosted FA24 at the time so we are glad we were able to work with Sprintex and Delicious Tuning to bring this kit to the market. While the tune Sprintex provided us with decent power and drove relatively well, we knew it needed fine tuning for drivability, proper AFRs, and knew there was more power to be found. Tuning proved a challenge especially with the torque this kit makes. We were experiencing jerkiness and tip in knock because the supercharger is so responsive and just made too much torque down low. Delicious tuning had to make custom tables to get all the drivability smooth so it feels like you are driving a normal car, but feels like a car with 2 more cylinders.
We recommend any customer buying this kit, get a Delicious tune also, as they know this supercharger on the FA24 platform. Getting that streetability, in our opinion, is the most important aspect. Yes, anyone can make the horsepower and the torque, but if the streetability isn’t there, you won’t enjoy driving. Please reach out to us with more questions or concerns!
