So yeah, I posted a similar thread on CNG being introduced in UAE, its still on the testing basis. My father has been working for this project until now.
This Chevrolet Caprice (5.7L ) is a first V8 in the country to be tested, it produces roughly 308bhp (20 which is lost over the years) and guess what it is running perfectly with not much of a lag in the performance. This kit can handle upto 500 BHP.
