Supercharger for VFSS

for the average bloke with a blown car, your not gonna kill a stock 6l80e in a hurry.

So much so, i use them for conversions in other cars/models with an aftermarket controller.

Not sure Mick. Seem to remember hearing a figure of $8k, but could be imagining things.

A new gearbox crossmember is required.
6L90E torque converter has a higher stall rpm. It is also a 6 bolt flex plate vs a 3 bolt
Software update is required in the tune for a different TCM within the gearbox vs a 6L80E.

Talking to a few Auto builders... the 6L90E isn’t bulletproof. Plenty have gone kaboom and sifting for gold in the trans pan. Yes they are better but still will eventually fail or need a freshen up with big HP and abuse.

The 4L80E is a stronger box. My bro is bolting one up to a LSX454 in a HK. Beauty of the 4L80E vs a TH400 is that you get a strong box with an overdrive. Great for cruising and getting the RPM down so the motor isn’t revving it’s guts out on the highway.

I think the biggest issue is "tuners" not knowing what they're doing with them. Seen loads of cars with the pressures jacked right up and the lockup removed, why I don't know!

Basically because that's what the ignorant used to do with earlier, far less complex boxes so more of the same. Unfortunately the 6L80 is a far more complex beast in which every adjustment affects at least one other parameter so is the quickest way to kill it. I only trust mine to Luis, the A6 guru. :thumbsup:

You give me hope Wonky. Mine has been tuned by Brad at Enhanced prior to any mods and is actually a far nicer box now than it was when i first purchased the car.

How much for this setup?

The kit used to be around the $12-13k mark, may have changed. Contact Yella Terra.
They're rear fed though, not sure who makes the front feed version and if they're easily available here or if it's a US thing if he's talking Chevy SS.

I enquired at a well known workshop here in Perth and was told that the front entry whipple supplied fitted and tuned was about $18000 a harrop 2600 about $13500 and lsa blower $12000.

for those in Adelaide Old willall guys

Hi guys

Is it legal in Qld for a blower to protrude through the bonnet.

Regards Dan

I can't imagine it being legal on any later model car.

It is hard enough getting something stealth & mild legally approved in most states.

That is exactly what I was thinking. Hard to find any straight forward legislation in any state of Australia, but bottom line is if you get defected I doubt the car will meet the emission requirements and on top of that would need to be engineered to have a blower (I assume you are talking about a VF that did not come factory fitted with a blower). I went to all manner of effort to keep mine hidden.

You can't have any moving parts unguarded so if the pulley was the highest part, it would need a guard of some sort around it. If its just the case of the blower then it can't pose a further risk to injury should someone end up on your bonnet.
There's also rules about affecting your field of vision but I'm assuming you're talking about a late gen car with modern tech blower, not some tall stacked 6/71.

But as the other guys are saying, even if it is legal, you've still got a massive "pull me over and defect me" sign on the front of the car. Best off just putting a cowl on it if it can't fit under the bonnet.

Yes I'm referring to my VF that did not come with a factory fitted blower
