How many of you guys are over spinning you're blowers ? I see some of yall with these small pulleys and simulator blower as me

Unreal

Been overspinning mine for past 4 years and 25k+ miles.

By how much? I have a v3t and a 3.47 on it

Unreal

2.70/8" Ysi to 7400rpm

Whatever that works out too.

75644 blower rpm

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.

Wow you are really working that lil blower .although it's max rpm is 55000 so it's more than mine . I have the v3 self contained

Unreal

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.

Just trying to decide if I want throw a Ysi on my car or not lol or hit it with a shot

Unreal

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?

curtisb23

Yea stock bottom end.

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.

Unreal

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?

Josh@AandASuperchargers

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.
