supercharger path? maybe?

[rdblan2]

I have been back and forth about supercharging for a while. Maybe I am ready now? No real need, but it's never about need!

I had Livernois do Kooks long tubes, 2C cam, roto fab, and tune about a year ago. I was worried about dropping a trans or blowing the engine so I didn't go supercharger.

Here we are now. Seems like most folks are saying the engine is fine (L99 for me) around 600hp, as is the trans. Opinions vary there and I get there is risk of imploding something under boost. I hardly ever drive the car. 11K in over 2 years with two or three trips to the strip in that time just to see how things would go. Not going to be a drag car, no slicks or drag radials in my future but would likely go back again just for the fun of it.

I've added some BMR suspension components recently: trailing arms w/ bushings, sway bars, end links, pro cradle bushings, toe rods, upper control arm bushing, strut tower brace. I think my suspension is good.

If I go supercharger, figure might as well do a stall as well to get rid of the little surge I have from the cam. Assuming all I'm missing is axles and drive shaft? Other than that, should I be good? Any good in porting the heads as well?

Talked a bit with a shop that recommended Whipple around 10psi to get me right at 600 rwhp. Thoughts?

shameless 24 hour bump for opinions...

The trans will hold 650rwhp+.
The stock bottom end will hold 700-800rwhp.

It all depends on your tune and your fuel. A good safety feature for high boost is meth. Make sure you have enough injectors and you have good fuel.

I've been at my level for 4500 abused miles running 89 octane through my motor and meth. Trans has been getting a little hot lately but a trans cooler will solve that.

A whipple at 10psi will give you more than 600rwhp. Go tires before a stall. A stall is going to make you spin like crazy.

I'd get a stall. I don't think you can really put a number on how much the motor and trans will hold some people have blown stock motors. Should it live at 600 rwhp? Yes it will be fine . There has been more than a couple car burn up the 6l80 and some like Jamie have made it live so the trans questions is still in there air.

[rdblan2]

Thanks for the opinions.

Thoughts on porting the heads? Seems like that's a mixed bag as well from the reading I've done here. Looks like some folks say it's a waste and others do it. Wish I would have done it when I got the cam and LS3 conversion.

And yes, definitely want a trans cooler w/ the stall for the cheap insurance.

[JLE58]

I wouldn't for what it cost. You could use the money other places on the car. Not much to be had with the stock heads they flow great like they are.

I wouldn't waste the money on heads. I still run my stock ones. Ted told even told me not to do it.

You seem like you have a good plan. As long as you stop there the drivetrain should last as well. Especially since you don't beat the car on a regular basis. Start with a blower and see how you like it. You can always add the converter later. Unless you really want the most out of the set up on the track the converter isn't really necessary with an A6(such a low first gear). You won't have traction with a blower, imagine that 10 fold.

[rdblan2]

Thanks again for the opinions. Looks like I'll pass on porting the heads then and put that cash into axles or drive shaft.

I guess I'll need to look into cost for the converter. I get the traction will be gone with the whipple and stock tires, just hoping to get rid of the little cam surge I have. Have never driven or been in a car with an aftermarket stall, so not sure if it's worth it for me or not.

2 suggestions if want to a supercharger.

First, do the L99 to LS3 conversion if you have L99. AFM lifters will not hold under boost.

Second, remove the cats. They will melt and chock.

Good Suggestions but Boost does not affect AFM Lifters, RPM Does.

I should have mentioned I have already done the LS3 conversion as well. Thanks for the thoughts folks.

Axles AND driveshaft. You will need both.
