First off,

what is more recommended with the upcoming V6? Turbo or Supercharger? I know that this can be searched for the I4 but with the different engine specs, would the turbo be a definate upgrade or would a supercharger still be a good consideration?

With the increase of torque, I think most of the Tiburon races will be lost when it comes to top end. Therefore a turbo would be the best? Though then again when you can rip the guy a new one right off the bat, theres no real need for top end cause they will think the race is already lost.

Personally I don't have the time for tuning, but I don't want to lose races. Like one time tuning is fine but I don't want to have to worry about it in the future type idea, other then general maintenance.

Also, with a turbo V6, what is a recommended diameter for exhaust? I was thinking of right now running on the highest potential psi on stock eternals FOR NOW.

To be honest the exhaust is the most important to me to get ready for well the next year.

(yes I m planning ahead too much)

Yes, you are planning ahead too much. Turbocharging a "V" motor becomes much harder because of the manifolding needed -- either you have to combine both halves of the exhaust into a single pipe and then run a turbo from there, OR you have to run a twin-turbo setup which requires much more intake plumbing. Either way it's a large pain in the neck.

Secondly, supercharging such an engine (with 2.7L of displacement) will require a much larger blower than is currently used on the 2.0L engines. The best bet in this case would be a centrifugal blower rather than a positive-displacement blower. Centrifugal blowers do not have "low end", they instead work like half of a turbo -- it's run from a belt like a normal supercharger, but the compressor side looks and acts like a turbo impellor. The result is a very peaky powerband, rather than a "fat" torque curve.

Both methods will be prohibitively expensive, will require months of research and development to do CORRECTLY and still must fit within the confines of what the engine can take.

The DELTA V6 engine that is being used in the Tiburon is also used in current Sonatas and Santa Fe's. This DELTA engine already has a LONG track record of being a VERY weak engine. The pistons are weak, the rods are weak, the crank is weak, main caps aren't girdled and the block itself is weak.

Sure, you can replace the pistons and rods, but you're still left with a block that can handle perhaps 300HP, maybe 350HP tops with good luck and tuning -- at least if history repeats itself.

There's no way to tell or even KNOW until the car has been out for a while. The engine HAS been out for a while, and the Koreans already know to stay away from it when talking about horsepower upgrades.

Why do you think they race Sonata's with BETA engine swaps? Sonatas didn't come with BETA engines, yet they constantly rip out the stock Sonata engine and swap it with a Tib engine whenever considering drag-race. Same thing applies here...

Red, I was reading that they've developed a new method for manufacturing the crank of the 2.7L being used in the Tiburon, so hopefully they've gotten rid of some of that weakness.

I did a post in the Tiburon forum about it a few weeks back.

Basically I would be looking at wanting to have enough power to take a Mustang Cobra or Camaro SS for say with this car.

Anything more and I will kill myself <img src=/images/forums/snitz/laugh.gif width=15 height=31 border=0>.

It's going to be a daily driver etc so I'm not going hardcore like you there Red hehe, but just wanna run some boost. So really I just want to be able to take an estimate of 2 seconds off my 1/4 mile time (granted the Tiburon will run between 15 - 15.5).

Red, I m gonna do a bit of research on the centrigrofal (lol whatever) supercharger since I think the torque is not needed as much for the Tiburon. I think it would be pretty easy since this is the picture of the 2.5L which is quite similar looks wise to what the 2.7L in the current Sonata is

<img src="http://members.rogers.com/rherfurth1/Sonata/PIC0011.jpg" border=0>

Out of a guestimate, Will I be able to get the performance needed circa at 8-9 psi to get what I want? (Probally note but I figured this would be the safest).

Also the Delta 2.5L is good with just a fuel pump upgrade for 90 shots of nitro. Now of course its not the same as running with pressure from forced induction but its proven to be a pretty reliable.

Any help would be great.
