N/A build or Supercharger build?

Hey guys, over the next fall/winter I'm going to finally take the jump and beast out my 2008 GT (auto). I've already done all the standard first mods such as a SCT tuner with JLT CAI, MBRP axlebacks and a tint job but I want more power The goal is to make a car that will destroy my fathers 2006 corvette yet still be decent fuel wise as the car is my DD.

I've priced out a N/A build which will include: VSR Comp Cams Stage 2, new heads (Either FR or mill mine out) FR Throttle Body, LT Headers (BBK with Cats), Intake Manifold and a Torque Converter. This will come to somewhere around $5000 plus the install.

This route seems overall more expensive then just slapping on a S/C such as a Vortech or a Paxton but also seems more practical fuel wise to my knowledge (remember my DD car). However a S/C is better bang for the buck and I don't want to waste money.

Furthermore, I really want to get gears. The 4:10's seem to be the best for Auto Trans but I'm concerned it will be too much with new mods and further destroy what little fuel economy I will have left.

Any feedback on which route I should take would be VERY helpful as I'm totally dead locked in which to do. Thanks AFM!

There is no comparison of the two methods IMO. The SC has always been the better route to take and as long as you stay out of boost (normal driving) your MPG will not take a hit. In fact, some people said their MPG slightly increased driving like a grandma with a SC. Also, I'm not a fan of SC other than twin screw manifold style SC. I got tired of the occasional intake air duct clamp letting go and having to repair.

IMO, go for the SC for the same (maybe a little more) money, but you will have more HP/TQ vs. the engine build.

Gas mileage...I run 3.55s with a Whipple and saw 29.4 mpg crusing at about 70 mph on a 30 mile road trip yesterday.

To answer your question. Blow it and forget about gas mileage.

My SC increased my rwhp far more than your proposed NA build (lots more) and also increased my mpg slightly, being a centrifugal. Gears not required with a setup like mine, I still run stock 3.31's.

what if the vette has forced induction. Test drove a 2001 C5Z06 couple weeks back that had a 427 c5r motor and other mods...about 550 hp n/a. You never know what is under a hood.

You're right, you never know. Stock Z06's are pretty quick, but ZR1's might present a problem...back to your point though, never know what they've got! Then again, they don't know what we've got (some of us who look and sound stock except for the rubber, unless they catch a hint of the IC behind the license plate)

Alright boys, the consensus seems to be edging towards the S/C route. When all's said and done...somewhere around 5k is the max I will spend after install. Should I get the Vortech S/C package for around $3900 (is upgradable later on I believe)? Are there any other parts I will need to buy to get that running efficiently (GT500 fuel pump)? The S/C option was less investigated than the N/A route due to the pricetag so a quick sum up of what I need would be appreciated.

Thanks for all the feedback so far!

Have you ruled out turbocharging?

I dont know about destroy a Vette, but 450rwhp will let you beat him with a good driver. Stock 2005 Vette can run mid to low 12s bone stock. Most Mustang with a blower on street tires will run about the same.
I would pass on the $3900 Vortech kit as it is not intercooled. If your gonna do it, do it right the first time. Get something that comes intercooled. More than a couple guys on this forum with the non intercooled setup that want the intercooler now.
And like someone else said as long as you stay outta boost you will be shocked at the MPG you can get. I have gotten 24-26 mpg on the highway with my Saleen setup.

For a NA setup this package seems well priced. The only thing I dont like about it is the cams. It will also need CAI(Which you have) and longtubes.

Did you ever narrow down your daily driver choice between the Vette and the Viper?

Maybe I will buy a 2016 Mustang GT, maybe not...

I can take a stock C6 by at least 4 cars in the 1/8th on regular street tires and I ran 7.70s with them. I maybe even a little quicker on the street because I hook better than on the track now that I have drag radials. I have done it more than once and that was with street tires and around 450rwhp. I think stock C6s run in the 12s. I don't think they are capable of 11s without mods. A 450rwhp S197 Mustang with traction and a decent driver is an 11 second car. Without drag radials its anybody's game though. They are the most important thing you can do to get the performance out of a supercharger on the street or the track. Believe me, "spinning aint winning"! Hotshot, you are correct about shredding that vette, get those 454 ponies to the ground and a stock C6 ain't nothing but a little toy to play with!
