Do they make tuner kits? Anyone know. Looking at options again, and the 2.9 isn’t enough.

They make all sorts of head units and I believe their bottom tub is pretty universal. Cowl clearance and pulley offsets will be your issues with the 3.3, 4.0, or 4.5 units.

We put a 4.0 mock up years ago.
Yep hood will need a hole in it.

They have different snouts.

Talk to Mike @ Whipple.

Well not cutting a hole in hood, do any of them fit under the hood that are larger then the 2.9?

The 4.0l won't work so that would leave the 3.3l option. However I have only seen that one used on primarily marine big blocks and I have never seen one with a jack shaft.

Maybe twin turbos (gasp) are in your future?



This is an ls with the 4.0l prototype. Notice much of the additional height is to allow for a larger intercooler. This 4.0l never went into production. Instead the production LS 4.0l is a rear inlet on the driver side.

Are we sure that blower wont fit?? It really doesnt look much taller than the 2.9 I have.

I'd LOVE to see this!!!

I’ve considered the TT or single option, am still considering it. But I really like the instant hit of a PD blower, my TVS is maxed @18psi and just looking at future options. Nothing right now but looking more towards next fall maybe.

Do a big procharger with a loose converter.

Pat would rather stab himself in the eye with a soldering iron than put in a looser converter.
