I'm running a 3.33 with 10% OD on a V2 T-Trim but haven't run it hard yet. Once Fran tunes my heap today I'll be beating the **** out of it lol. Before that it was a 3.47 and it's been fine, the blower has been on the car 3 or 4 years and it's been a hard couple years so I wouldn't stress it to much. There's guys spinning smaller blowers helluva lot harder and they live.

Just be prepared for more often rebuilds. ~$600 for vortech to rebuild it. Being overspun like that I would expect to spend that every 2-3 years.

Focus on hitting whatever your performance goals are first. The Ti trims are amazing blowers. Should put you well into the 9s or 180s in 1/2 mile. I wouldn't consider upgrading.

I'd just throw a small shot at it. Those ysi need to be spun and your still stock block right?

I don't over-spin Self-contained blowers.
I love to over-spin Engine oiled blowers.

Curtis if you're not ready for the Ysi upgrade, then put a small shot on the current combo.

What is the concern with over spinning the self contained blowers?

Not questioning you being right, Just wanting to understand.

Self contained don't run the HD bearings
Self contained don't have a constant supply of cool oil.

Would a V3 Si w/ 3.4 & 10% od be overspun? If so how bad?

That would hit 56,000 impeller speed at 6600 engine rpm. Max rated is 52,000 impeller.
Here is the link to the Vortech calculator for others to use too.
