Hey Everyone,
I bought my 2017 Hyundai Elantra Sport (my second Hyundai Elantra) back in early March. I actually had quite an ordeal getting the "Electric-Blue" model with a standard 6-speed manual. The wait was worth it.
I am a longtime SCCA member and active solo racer. I purchased my Sport with the intent of competing in the H-Street (HS) SCCA solo class.
In the HS class, we are allowed to replace the OEM spec paper air filter element with a K&N filter drop-in replacement filter. Which I have done.
We are also allowed to add, replace or remove the front or rear sway bar - but not both! I plan to remove the front sway bar.
We are also allowed to use any aftermarket or racing coilover shock assemblies (with any custom shock valving or methods of shock valve adjustments), but with no ride-height adjustments on the spring perches and must use the factory OEM coilover springs. The original factory ride height must be maintained.
We are allowed any aftermarket catback exhaust system or muffler (behind the original OEM catalytic converter), but must exit out to the rear of the car.
In addition, we can go up or down 1" in wheel diameter, but must strictly adhere to factory wheel offset and rim width.
Any size tire may be used, but it must be have a 200-treadwear rating and must be available in at least three different tire diameters with a minimum of 8 different aspect ratio sizes.
I have currently tested and run my Sport with some TSW Nurburgring 17" x 7.5" lightweight alloy wheels wrapped with some P255/40ZR-17 Hankook RS4 tires. This tire/combo fits without any issues whatsoever.
The Sport in this configuration handles incredibly well.
The only issue that I have encountered is that once I am deep into the throttle on the course and have to back off and slowdown for a curve or turn and then try to get back into the throttle --- there is absolutely nothing there! No power whatsoever, it's as if the whole engine was completely shutoff or the ECU cut all the timing & power deliver out of the engine!!!
Any ideas why this is happening???
I even "watered-down" the intake manifold and the intercooler with a portable garden sprayer between runs, but to no avail.
Would appreciate some advice on what to do to alleviate this major power delivery issue.
*Special Note: We are not allowed to mess with, alter or replace any of the stock engine or turbo components on the vehicle as delivered from the factory.
This is the first turbocharged vehicle I have ever owned or raced.
Thanks!
Luis
