Tips on adding 20-25 HP
Hello everyone. Its been about 1 year since i last logged in. Anyway, I'm looking for the best way to add about 20-25HP to my 05 c6 auto. Car has 31k on the clock. Only mods are Corsa Sport. I have heard that they add zero HP, but from other sources maybe 5-8 hp. I was thinking about Vararam snake charmer but am worried about getting caught in a rainstorm. Any suggestions to achieve my goals without getting to costly?

I have an 05 with MN6, mods include the tune, 160 stat, varraram and complete Z06 exhaust (manifolds back to mufflers). Did not have the exhaust on last year when it was dynoed at effingham and pulled 360. Do not have the before (tune stat and varraram) numbers but normally 340-345 is in the ball park. so safe to say 15-20 with those mods and hoping for another 15 or so with the exhaust. May get a chance on the dyno this year and effingham and see what the exhaust did for me. Hopeing for 375 which would be an increase of 30-35. May try to get a ported throttle body on soon which should be good for another 5-8.

Start with a tune for sure. A good tune will transform your car's performance...especially with an auto....the difference in shifting alone is worth it.
As far as the Vararam rain myth...there have been thousands upon thousands installed all over the world in every climate, including places like FL where it often rains every day. There has never been a single report of water problems from driving in the rain. The very few instances where any instance has been reported has been where someone had driven through standing water so deep, that any bottom fed CAI might have had problems (as well as the fender mounted ECU).

If you do a little research here on the forum, you will find numerous posts about his work and reputation, made by his customers all around the country and otside.
As always, the phone is the best way to reach him and that is 914-332-0049. Give him a call if you have any question, you will not be disappointed.
Btw, Craigster05 is right about the Vararam, you'll have to be concerned about it when your car is in the water up to about your hood emblem and by then you'll already have bigger problems to worry about than the Vararam

Like some have mentioned. A tune, which most will go to a 160 thermo, and some kind of cold air. Probably the most bang for the buck.

I'm looking to install some QTP Cutouts soon.... the toggle switch that comes with it allows you control how open they are, you dont need the fancy digital switch.
I talked to QTP the other day, and they told me wide open that the cutouts were worth 18rwhp.
I don't know if that's trure, but that's what they told me.

I would recommend against the vararam. Do a quick search and you will see the nightmare that so many have encountered with the build quality and warping.
You will fail with longtubes immediatley if you dont have your car tuned. After a tune your car will pass the sniffer and will not throw any service engine lights. TECHNICALLY you could still fail a visual inspection, but I've NEVER heard of someone failing visual inspection as long as they have highflow cats installed.
I know many people in the New Jersey area with longtubes, cam, heads, etc...

Headers and a tune will be about 2k and will net more than 25HP.
The corsa added nothing but noise.
You didnt define costly.
A cam even without headers will net 40 at peak but nothing down low and needs a tune.....also 2000 bucks.
Gears are $2000 with a tune and will make you just as fast 0-60 as a cammed car.

Wake up call
I just put in a ported throttle body in my LS3 and I love it. I posted a link to a Vetteweb magazine article in another thread that said that the TB is worth 13 RWHP. The biggest difference is the feel of the car. It is much more eager and fun. The throttle response is much better.
Call Vmax motorsports. $150 plus core charge and shipping. You put a fresh one in and send the old one back.
Enjoy.

Definitely something I would advise any do-it-yourselfers to try.

I`m sure with a good tuner ull see about 15-20 hp with no cost .... but I`m afraid you will say "later on" I need 50 more ... then 50 and 50 and 50 and 100 ...... same what I did and I spend about 40K on my car started like you looking for 25 with Corsa and Kooks ... then I was looking for 30 more with CIA .... then for a 50 with Cam .... now ??? APS Twin Turbo Kit and forget engine ... looking for more 300 ! don`t waste your time ... If you are going to do something just go ahead and go for Supercharger or TurboS cause small numbers will not END ....
