Whipple 2.9 Supercharger for the G8

There is a Whipple 2.9 available for G8/VE in Australia from YellaTerra. It has a front drive and rear air flow entry.

Has anyone seen the Camaro and Corvette version (front drive and front air flow) adapted/modified for the G8?

Haven't seen anyone do it.

I would have LOVED a Whipple, but I was worried about the amount of fabrication to get one to work, as the hood clearance issues you'd probably run into.

It's too tall for sure. A Maggie 2300 pulley already rubs the hood liner. With the height difference of the whipple, I'd say it won't work

I just bought a 2008 g8. It has 63k miles.
I'm a big German car driver, so American is new territory for me. I'm looking for mid 11s in the quarter. What's the most reliable way to do this?
Keep in mind this is my every day driver so it has to relatively easy on the motor.

I wanted a whipple. Cam/dod delete Maggie should be easiest

The Yella Terra guys Down Under have a rear feed version of the 2.9 and 3.4 Whipple that fit under the hood of a 6.0 litre VE /G8.

Anyone in the USA doing this?

I already have the maggie 2300, but would be very interested to see if this can be done and at what cost.

I am told that a Whipple 2.9 kit with front air feed that is available for the Corvette will bolt straight on, but that you need to "drop the subframe" a bit. What does this mean? What subframe and how would you do this?

I'm pretty sure the subframe is a separate frame to support the engine and or transmission. It either bolts up or is welded to the frame. I'm sure they mean to drop it so that it will lower the whole engine, providing room for the bigger 2.9 whipple. Well I shouldn't say I'm sure, more I'm guessing haha. But I have no idea how that would be accomplished if its welded without some serious fabrication. I don't even know how it'd be do e if its bolted for that matter. Someone with some more knowledge then me chime in

Interesting. One thing the Yella Terra site says is that for them to make it fit, they used engine mounts from an LS1/2. No need to drop the subframe. If that's the case, then I would worry about header clearance....

The current front inlet units from Whipple for the Camaro and Corvette seem interesting as well...

Yea because that would lower the motor quite a bit. I'm already low as it is and my headers scrap everything.

It wouldn't really make the sub frame closer to the ground , it would raise the body more .

Does anyone have more info about how to lower the sub frame (and therefore the engine) in a G8? I don't think I would really do this - just curious. I imagine it would lower ground clearance of the exhaust/ cats, so not a great option I guess??

Picture posted on another forum of a Camaro Whipple installed in a VE in South Africa. The guy said he "dropped the subframe".

I am told that the engine sits in a separate subframe that is secured to the body by 4 16mm bolts and that it can be lowered by adding some washers or other spacers. It does obviously lower the sump closer closer to the ground.

How tall is the Whipple? I fit a single plane and elbow which was taller then the Maggie under the stock hood, granted I removed the useless hood liner.

Just another 9 second family car...
