Most TT kits on the market spool very quickly anyway and the NA driver will not have any lead, at least once the boosted car has traction. Simply put NA with a VQ is not worth it at all. Same if not more cost as you still have to build the motor and you will be lucky to get 300whp. Boost it. As long as you get supporting mods and everything is done right it will be a reliable car with no issues.

 

ah! just as i was almost decided on NA, mostly because ive heard of boosted cars not running right at higher elevations in the canyons, which would be the number one thing i would use my car for, canyon runs.

 

nice, but those things are crazy expensive compared to my $350 utec. and im not trying to build a drag car, primary purposes will be canyon drives, some autocrossing, and nice day cruises.

 

The KP Technogies unit is $130.

In fact, I have a brand new one I have never used I'll let someone have for $100 plus shipping. Just PM me.

 

Whoever told you that isn't right. Boosted cars perform much better at higher elevations than NA. Turbos loose less power with altitude versus NA cars, however, the thinner air a high altitude makes the turbo work more to keep the boost the same as they would at 2000 feet. The car will run fine but pushing it at a canyon day after day might cause you to have to rebuild the turbo(s) sooner.

If you're not at that of an altitude (10,000 ft+) the strain on the turbo probably won't be that big of a deal.

Here's an example I found:

For every 1000 feet you climb above sea level, there is a reduction in air density of approximately 4.5 percent

Let's see

Carrera GT = 612 hp @ sea level

less (5.280 x 0.045) = 0.2376 or 145 hp, netting 466 hp in Denver
less (8.500 x 0.045) = 0.3825 or 234 hp, netting 378 hp

At 7153 ft, both stock 996TT and CGT net 415 hp - the beauty of turbo charging!
