What is the difference between the 46mm and the 38mm Tial Wastegates offered by SpeedForce Racing? I'm going to upgrade my exhaust to their 3 inch with the sport cat, as well as get a new WG and Innovative WB A/F kit, just curious as to what side I should order.

Thanks,

Chris

Bump!! Anyone know the difference?

What is your expected power output. I couldn't see a 38mm being TOO small. A 46mm may be overkill for your application. The difference is in the OD of the valve.

How much hp are you planing to run?

ChrisJ951

My goal is 400 rwhp, but I want that to come at as little boost as possible, nothing over 20 psi. I will eventually have a comeplete head and intake job, 3 inch exhaust with a Vitesse stage 3. I have a LR stage 2 intercooler on the way.

38mm is more than enough

When I was buying my wastegate I asked Tial techs the question on flow, they told me the 44mm flowed as much the 46.....!!

Some people here would buy the 46mm and pay the extra money knowing that it flows just as much as the 44mm, because BIGGER is ALWAYS better.
