Oh ya for got the exhaust, just got that done, catback straight pipe hehe :-)

Just remember...modification is like a chain reaction, one mod can easily either improve or hamper the performance of another, like the idiots who upsize the turbo plumbing on their Lancer Evolutions and conveniently forget to swap their compressor housings to compensate for the pressure drop.

Just think it over rationally before you begin to tune...

The Stock 2.0 Tib Exhaust cam is better than any other Exhaust cam made for out cars from Hyundai. No need to change that one! smile.gif

Ahh thanks, I was wondering on that one :-)

Still you think that a exhaust cam with higher lift would benefit just a much as an intake with higher lift.

Random

it really depends on the timing of it, not just the lift. A turbo exhaust cam might benefit from stock duration or only slightly longer, but higher lift. A N/A exhaust cam would benefit from longer duration AND an increase in lift.

Superchargers sort of fall into the middle ground. Depending on the engine and exhaust setup, some work best with turbo style cams of high lift and short duration, others work better with NA cams of medium/high lift and longer duration. As there are not that many cam choices out there for us...it's really a rather moot point. Unless you wanna blow about $5000 in buying every cam you can find and testing them all...

Here's my 2 cents...think about how you drive the car and what you really want; with a turbocharger you have to keep the engiine in a certain RPM band to make full use of the turbo(boost threshold)...with a supercharger you have boost from the get-go. What cams do, besides lifting the valves in varying degrees to improve or make whacked out the flow characteristics is shift the powerband either higher or lower, so you can guess why radically tuned race cars only work well in a very narrow powerband of say like 800RPMs in width while a street driven showroom stocker has a powerband of like 1200RPMs in width.

When you know how you drive the car you'll be able to affect a much more effective tuning, without changing your driving style too much, and it'll also help you to choose between a supercharger or a turbo.

Good luck man!
