Whipple Superchargers, the supercharging experts are proud to announce the release of the much anticipated W275ax 4.5L supercharger lineup.

The new W275ax twin-screw supercharger is the latest supercharger added to Whipple's offering. With unique benefits such as a new 12-rib serpentine belt system, HD drive, oversized oil capacity, new rotor profile, new rotor port timing, multiple discharge pressure ratio options and oversized bearings.

While boasting all the new features, the Whipple W275ax (4.5L) is the identical height and length of the popular W245ax (4.0L) giving the 4.5L little issues for fitment yet giving a significant boost in potential power.

When is the 10 litre going to be available?Now that PSI is out of business,the timing is right.

Its on the board, but the race market is soft....

Nice! How much more power does the 4.5L make over the 4.0L?

Just depends on the power the 4.0 is making. At 1000hp, it makes another 60-80hp with no changes. But also has more capacity to make far more!!!

It looks physically similar (or even smaller) than the 3300. Is it?

I am a Whipple fan also but since when is PSI out of business? I thought I saw something new from them not that long ago....

Just curious.

Call them.Doors are closed and they filed BK.

That sucks, PSIs looked mean!!

Just talked to them wed. They said six to ten units available by December. Maybe they lied to me?!?!
