i do a lot of turbo fabrication. what is the boost limit of the ls-2?

can the rear end handle the extra power on a 06-07?

what is the rear end limit if i use drag radials? not really planning to race it, but you never know.

is there a setup for a solid axle conversion??

I think the rear end limit with drag radials is well below stock level

All of these questions could be answered via search.

The quick and dirty:
Unsure of the boost limits of LS2
Yes, the rear can handle the power, hell I have almost 600 at the crank and original diff. Depends on how you drive it.
There is a solid axle conversion via madman racing. I've heard rumors from $7500 to $9000 for the conversion.

The madman setup is irs not solid. Yeah just dont let it wheelhop much and you will be fine with the added power.

Really? I thought we had IRS on our cars in stock form? what is the difference between Madmans IRS and ours? Just beefier?

Back to the original question, does anyone do a solid axle swap for the V then?

The difference in Madmans IRS is..........
9" center section, bigger axles & cv joints & the way the cradle is
mounted

The pics are ugly! That kit is the true meaning of function over form. Luckily it's all tucked under the car!

it isnt so much boost limit but the volume of air you are able to move with x sized turbo.

stock bottom end on a lsx v-8 would be about 12-15psi. that coming from a friend who has messed with ls1's and turbo's since the beginning. hes pumping 850whp in a SS single front mount. from what he has explained to me you can run more but its pushing it depending on the turbo size and so on.. he also says to run a catch can..the v-8 block build alot of pressure under boost and shoots it in the intake alot quicker than NA.

...a good tune goes a long way too when you start getting up towards 15psi on a stock bottom end.

I wouldn't go above 8 pounds if it were my car. If I added meth I might go up to 10/12 but no more for me.

i think the first key is what turbo/sc are you talking about making xlbs of boost with.

Plenty of C6s and C5Zs over 12psi on stock motor, view corvette.com, the FI section, you will be surprised at the set-up on some of the cars. Good tune + good fuel + good install + meth kit will instill confidence. Not sure of strength of rods and pistons when comparing LS6 to LS2---anyone know, the crankshaft is not the weak link, as I have never heard of one breaking. The above opinion is for a DD or a car that is not abused 100% of the time. If one were building a dedicated drag racer, I would say ditch the stock motor and spend some money on a built motor.

As stated by many, the stock rear is not even good for 400HP, it is a major POS. Drag radials will get you one step closer to grenading the diff, many including I can attest to this. The V is not a drag racer unless you swap out the rear and axles, anyone who has gone to the drag strip and driven home was not pushing the motor to its limit. I could destroy any stock rear with a couple of hard launches and/or hard shifts. Know the V's limits, it is a great car, a proven Autocross or Road Racer, just not one to bring to the strip in stock form.

Damn straight, and points for acknowledging the stock motor can handle the boost.

to me the best fix for the pre 09V rear is jsut to sell the damn thing and get one with a real rear end

I know I haven't pushed it yet. I want to...badly, but I'm keeping my 60's to 2.1-2.2 and granny shifting 1-2. I've got 9 passes and every one I've held my breath.
