I got pulled over today and the cop'a reckoned i needed an engineer's certificate for my turbo installation, Is this true? I was under the belief that because i still had the original motor in the car it didn't matter.
yeah unfortunately you need an engineers certificate to turbo a car, even if your car came in turbo as an option (eg. XR6 & XR6T) but yours isn't a turbo, you would need an engineers certificate to legally turbo it. out of interest what did the cop end up doing about you not having the certificate??
Here's some pic's for you, its a work in progress, am running straight gas, and are yet to add second converter and intercooler, which i hope to not have to put on hold to get a engineer certificate. I am running 15PSI and it puts out 150 rear wheel KW's at 3800RPM and then it run's out of gas.
150kw's at the back wheels is all you will get on gas with one gas converter in an auto, according to gas research the highest they have gotten at the rear wheels with one converter on a manual is 175kw, that's why it doesn't make anymore power after 3800RPM. with two converters it would be much higher, and the touque figure on the dyno was 6500 neutons.
good stuff dude.
As far as an engineering cert no I don't think you should need one.
They are mainly for structual or safety to cars like chopping the roof, making a 2 door or mods to brakes.
The only thing that could make it a valid defect would be an emmissions test but if the car can't physicly run on petrol then they'd have to take the gas messurments which would be carbon dioxide and water as LPG has near zero emissions (hence it's use in factories for forklifts)
Call the testing centre and ask them dude. Cause it's differant from state to state.
