Patient Zero represents more than $70,000 in upgrades and refurbishment on top of the original vehicle. For someone looking for a fully developed Plaid rather than starting with a stock car and building it piece by piece, this is the complete package. Thai Hot tune is intended for off road use only. All terms and conditions from installed aftermarket products apply.
Street vs. Race Configuration
THAI HOT can be configured to perform similarly to Very Spicy during normal operation, while allowing the full THAI HOT power level to be unleashed in a closed course race setting.
Important Risk Information
THAI HOT is best suited for smooth racing surfaces. Using the higher power settings on rough or uneven pavement, including typical public roads, dramatically increases the likelihood of blowing the main pyrofuse due to rapid torque fluctuations. Use on a smooth drag strip or other smooth closed course racing surface is strongly recommended.
If you use THAI HOT at its more aggressive power levels, assume that you will eventually need to replace the pyrofuse and keep spare pyrofuses available.
Pyrofuse replacement requires exposure to high voltage components and should only be performed by someone qualified to work on high voltage vehicle systems.
If the pyrofuse activates, the vehicle will immediately lose propulsion and may come to rest in an unsafe location or create a hazardous situation. For this reason, the higher THAI HOT power levels should never be used outside of a closed course racing environment.
Assumption of Risk
By purchasing, installing, or using THAI HOT, you acknowledge that you understand the risks associated with this race only product and voluntarily accept them. You assume responsibility for vehicle damage, vehicle failure, loss of use, costs, injury, or other consequences arising from its installation or use.
SirHarrold Performance assumes no liability for damages, losses, injuries, or claims resulting from the installation, configuration, or use of THAI HOT.
