Need your help in making a decision!
Thanks in advance for all assistance. I have a 2001 C5 coupe that I love the look of. Lots of enhancements on exterior and interior. Unfortunately, I am unsatisfied with the performance. It has Cartek 3X package with 413 rwhp 390 ft pounds torque. I have Cartek clutch, LS6 heads, ported LS6 manifold, 3x cam, TPIS headers, random technologies cats and x pipe, 390 gears, 6 speed with B &M shifter, and the list goes on. Bottom line is that it is not fast enough for me. I drove a new stock C6Z06 and was shocked at how much faster it was than my ride.
I am contemplating a Ligenfelter twin turbo 650 hp package. I am trying to justify the 25k PLUS investment in this car that is 8 years old with 28K mileage. Obviously, I will be keeping it forever after this waste/investment in it. All thoughts appreciated.

Will put you right around 500-540' ish rwhp...

The problem with going to a supercharger at this point is that the heads that I have were done for a bit higher compression as was the cam. I probably would have to get new heads and cam and then, I might as well get a new engine or have mine forged, no?

Too much money!
I would seriously contimplate doing a Centrifugal supercharger and making it safe and having tons of HP and TQ !
Why A&A has a special for $4500 right now in our section!
Make it have 650 RWHP for way less and that's at the RW's and not the motor
Thanks,Matt

I'd either add a 100 shot of juice for special occasions or sell the car as it sits and buy a real low mile C6-Z06. The added power from the new Z will probably keep you happy for a while, and then if you do get the mod bug you'll have a much better platform to work with.

When I received my 3X package from Cartek back in 2004, their in house cars were getting 450 to 460 rwhp. After receiving back my package, having it installed, and dyno tuned. The results were a high rwhp of 413. I was told that the cam on their in house cars had higher lift and required fly cut pistons. I was also told that the my tuner was the problem. Needless to say, after researching the heads /cam package back then and coming up with Cartek being the most reliable for high horsepower I was extremely disappointed. My belief is that the LS6 heads that I received from them were way below par.

Had a similiar experience.
There are power adders that will easily enable your C5 to beat any stock C6 Z06. You could even replace your motor with a 427cid. All GM did was do what many have been doing for the C5 over the last 8-9 years..which was to add a big displacement small block. There are 600rwhp 427cid setups....the stock C06 Z is like what 450 rwhp? The extra power you felt while driving the C6 Z is in the SOTP and is due to it weighing a few hundred lbs less then your C5 and about 20-30 more hp & tq....weight reduction and tq equals faster.

You've invested in a certain level of fun and capability and now you want something different. Simple as that.
Not to get to far into things, here are the directions I'd consider.
1 - Recognize that you have an awesome package, the pieces of which still work well together. Also recognize that over time, newer capabilites have come on line that eclipse what was once top of the heap. Finally, it's paid for. Decision: Keep the car and continue to enjoy the heck out of it.
2 - If you have deep pockets, mod the car to meet your new capability desires.
3 - Keep the car and buy a C6Z06.
4 - Sell the car and buy a C6Z06.
If only one car is an option and based on finances, I'd vote for either 1 or 4.

$25K for a 650bhp kit? Don't do it man. There are several vettes out there able to wax a C6Z for less than that total investment.
What I would do if I were you is -
1. Sell your car and get a C6Z with the money.
2. Throw a FI package on your car (not that hard)
3. Sell your car and get a hooked up C5
I was trying to sell mine not to long ago for low $30K. It's not funny how slow a C6Z looks when I blow by them. Go look at some of the options there. Some with built 402s going for mid 20s ect. You could throw whatever at those motors and they'll take it.
Good luck
PS. Lingenfelter price is 50% name 50% performance.

From: ECS : WTF did you break now and HTF did you break it this time
call up ECS, I think their built motor 346 package with a paxton is around 25.....should have you pushing 700-800 at the wheels...
and you'd be able to sell off your current motor, reuse all of your exhaust etc.
or you can go simpler and get a set of unmilled 243 (C5Z) casting heads to get your compression back to stock, swap the cam and just throw a blower on that with meth and have around 550-600 at the wheels for alot less than the 25K lingenfelter wants. At the same time You'll have some bling under the hood to look at, the damn lingenfelter cars........you can't see a thing except from under the car...for all that money I wanna see somethin!

Sell your LS6 heads, pick up a stock "unmolested" set of LS6 heads for say maybe $300-500, put on a fresh set of Patrtiot extremes $300 and fresh set of GM MLS gaskets $80, leave the cam in there.
Pick up a A&A kit on sale for $5200
Add a meth kit form ECS $599
Add a BAP and Racetronix hotwire kit $ 369
Labour to all the above would be around $3000
Total would be around $9900
And would net you around 650 RWHP! OR as LPE wopuld put it 760 HP.
