So, it's not Like GM dropped the ball.


I guess you could make an argument that GM should give you some power train warranty if the LS9 blower and their tune were the ONLY mods done on the car....



But in reality how many blown cars are without any other mods...

I'm guessing, not many.

Plus....I have a funny feeling this is going to be popular with Corvette enthusiasts rabidly searching for Positive Displacement applications that don't require raised hoods.

And knowing it's been GM validated/tested is always a good thing. To protect themselves in OE applications, they always tend to overbuild things. This is a major plus for the person not interested in a warranty.

Next we have forged 9.1.1 Pistons on the LS9 and on the LS3 we have Hypereutectic aluminum at 10.7.1, And one more thing the LS9 has that the LS3 dos not have is the oil squirters that add oil to the rods and underside of the Pistons, In order to add the oil the LS9 oil pump has more volume on the pressure section than the LS3 by about 20%.

This is a grate new part, but if you think you can get a warranty i have a bridge for sale for you too.

Roush, Saleen and other retain warranties through Ford. I just wish GM would do the same.

Where is this bridge and what do you want for it? I will install some tolls and make some money to pay for all these damn mods I want to do! Won't need a warranty if I have enough quarters to get it repaired if needed

Excactly! Why would this be so difficult for GM to do.

Very good points.

Or will it be only select dealerships that can actually do the install?

Why does it show a price drop of $1,000 on the 2nd day it's offered just seems weird.

And I understand this will work on the auto L99 but is there an extra cost involded by getting rid of the AFM or VVT? This is something that is done with the tune correct? No additional hardware or work needed to put it on the L99 I hope.

What do you guys think?

I'm sure most if not all dealerships could easily install the LS9 roots blower. Tuning it is another matter. If GMPP releases some canned tunes, that could make the dealer install option pretty easy.

But, most likely, the tunes will have ot be custom. If that's the case, wouldn't you want a qualified LS tuner who works on LS engines every day? Dyno tuning would be the way to go and most GM dealerships probably don't have dynos.

Of course, the GM dealer who installs the LS9 blower could rent some dyno time, but still it would be better to get the tune by someone who has tuned many C5 Camaros.

Regarding the warranty, your warranty will be gone. That's because a custom tune will be needed and that in itself will void your warranty. Even if GM releases some canned tunes (very unlikely) you would be lucky if you received some very limited engine/trans warranty.

The LS3 and L99, while strong and powerful engines, were not designed for forced induction like the LSA and LS9 engines. Of course, we all know that the LS3 and the L99 can perform and last (so far) at moderate boost. But I highly doubt GM will warranty a stock LS3/L99 with their LS9 blower.

Plus, if I'm not mistaken, the LS9 in the ZR1 runs something like 10 psi (please, correct me if I'm mistaken). If that's the case, you wouldn't want to run that much boost on a stock internals LS3/L99. Although some owners are doing it, it's not the greatest idea without meth or really high octane.

My understanding is that the LS9 roots blower can work on L99's. AFM can be deleted with the programmer (tune). VVT cannot be deleted without replacing the camshaft for an LS3 or another one and adding an cam phaser restrictor. That's about $2K.

I don't think you have to get rid of VVT in order to install this blower on the L99.

My thoughts are there are better blowers on the market. For the price, why get this one? Sure, the LS9 engine with all of the awesome internals is a work of art, but the blower itself is probably not the best bang for the buck. Just my opinion.

I assume there's differences with the LS3/L99

The best thing about this news is that GM is showing us that the stock LS3 and L99 as well as their respective transmissions and rear ends can handle moderate boost.

As I stated above in my other post, I don't think GM will honor the factory powertrain warranty once this blower is installed, but at the very least this shows that the stock SS Camaros can handle upwards of 500 rwhp because GM wouldn't sell this blower if they knew otherwise.

I'm speculating that the LS9 blower makes at least 500 rwhp on a stock LS3 at 8-9 psi.

Huge differences. LS9's have forged internals and oil squirters in the cylinders to cool the rods and pistons. LS9's also have lower compression and a stonger oil pump.

I just asked them via e-bay regarding the warranty...as soon as they respond I'll keep everyone posted.

Thanks!
