Are there differences in the kind of air spitting sound when it comes to the Tial 38 and 44?

I've only ridden in a car with a 44mm, so I can't say from personal firsthand experience. However, I've read that the 44mm isn't AS loud, but it's still damn loud.

What constitutes what size we need for our cars? I see everyone always goes with a Tial 44m and a few go with 38mm. what constitutes those sizes and why always that brand?

The real two brands that are used are TurboSmart and Tial. A lot of people use Tial ..

The difference between the Tial 38 and 44 is that the 44 uses a V-Band. A lot of people have had problmes with the 38 and 44 has no problems. Although it has been said that if you use a quality flange or gasket or something for the 38 .. It won't be a problem and it'll save you more money.

Tial is just the most popular, with TurboSmart being the next in line. Some people choose 44mm over 38mm due to sound differences or the 44mm having v-band clamps. Another theory is the 38mm is for high boost applications and 44mm for low boost. Also, I read something about not being able to run leaded gas with 38mm if that's a concern.

do you have to take the turbo out when installing the uppipe? is it worth the money to buy the uppipe/EWG? has anyone did it themselve or should be professionally done?

Roccrew585 · 11-05-2007, 06:50 AM
