what is the difference in the ls9 and the lsa in the cts-v? other than a few hp.

 

Lots. Bigger supercharger, rods, pistons, oil system, heads, block, and so forth.

 

If racing for 40 to 70 or on the highway in general is you thing....sure....especially high speed highway runs (though extended 3rd/4th/5th gear runs at full throttle with a blower on a stock bottom end might not be a wise thing...think heat and cylinder pressure).

 

Yo...... its on ebay already!

Not racing from a roll like a BPU supra youtube video, I'm talking more about coming across an opportunity for WOT in normal driving. Passing situations on 2 lane roads, and just plan ol' getting lucky and having a big open stretch of highway in front of you, those things involve WOT from a starting point somewhere between 40 mph and 70 mph.

Again, I tend to agree with your premise that boost requires lower compression, and perhaps forged pistons. But I haven't seen any reports of these bolt on Magnuson kits grenading engines, so maybe it is okay and reliable if the boost is low enough?

Personally, I think N/A would be better for simplicity's sake, but the blower is an interesting option, and avoids any risk of messing up stock idle and low speed drivability - i.e. if the car in stock form can idle up a parking garage in 2nd gear, a car with this blower kit could do it too, but a cammed car might not be able to.

 

why did they leave the stock air box on?? wouldn't it benefit from an open box or CAI?

 

What a joke. Here's his price break down.

I'm stunned at the prices. Why would anyone go to this guy? Having lots of money and they just want a Hennessey tuned car, I guess. I'd think I'd just go with a LS9 crate motor and swap it out myself.

 

Yeah, Hennessey is always like that. If you ever do the swap, post it on here, I bet plenty of us would love to see it.

 

I just checked to see if Lingenfelter had prices up yet, and sure enough they do. $11k for their 550hp supercharger install.

This makes Hennessey's even more insane.

 

The block is the same, and I think the heads are too.

 

so if you concidered changing the ls3 to an lsa or and ls9 you might as well buy the crate motor?

thats not too bad of a deal for lingenfelters package. the 570hp package. i couldnt do the 650 hp for 19k. but the 10k for the other is not bad. the supercharger alone is 6-7k from magnuson.

 

Well, I'd drop in a GM crate motor before going to Hennessey, no doubt about it. But if I was going the supercharger route, I think I would go with Lingenfelter. I think their packages are a great value and the company has an excellent reputation. But I can see the fun in working on the motor yourself, so I'd be tempted to go that way as well.

 

It still boggles my mind that this guy is still in business, considering his history with customer "service".

 

you gotta remember that alot of these people that go to companies like these, have the money to pay the price and have the money to take it back and have it repaired by them. in the end the money is no object to them and they will pay for whatever is needed.

 

There is so much potential in the LS3.....Personally....it would be a long time before I'd move away from that basic package.
