I should have added a little smiley at the end of my sentence; no harm no foul

 

I think that more than HP you should state how much money you are willing to drop. As awesome as a full race kit may be it isn't complete.
You still need to figure out fueling and engine management. Not only that, you need to either relocate the stock battery or buy a smaller one. Its a lot more work than it may seem.

Personally i dont like superchargers. They are too loud all the time. Its kind of annoying. But as far as i know you can get a solid 300 wheel reliably. Although the same goes for the Greddy kit. I don't know anything about it but i'm sure its plenty reliable and will make good power. But not 400. Sorry.

The first logical step when deciding you want more power isn't to set a goal for yourself. Set a budget first. Then you can decide what to spend your money on. As much fun as a 400 hp car may be, remember that your stock drive train may not feel the same way. Replacing clutches isn't fun or cheap.

As far as gas mileage it should remain close to stock as long as the engine isn't under enough load where it produces any positive pressure. (like highway driving)

In any case the tune can make or break your power goals. Find a god tuner and you'll make strong power no matter what choice you make as far as FI. It's been said time and time again but far to many people don't listen.

Good luck!

 

EVF2000 has over 400whp with a vortech supercharger. But he has been through one motor to do so. But i think he is pushing a 15lb pulley or something. first thing you need to do is look into reenforcing your block if you want to go over 400. But no matter what you do. Have fun and good luck.

 

When you are standing on the sideline, you may think 400 HP is enough to boost your ass around. So, SC may be a good option to your objective.

Until you stand side by side with 350ZTT, Z06 and the gangs, you will regret of spending on SC and will start all over again to build your turbo kitchen.

 

i was just messing with you Spec! I thought that would be a funny time to mention that war of words you had about the stupid "torque guy". You definately know a hell of a lot more about this stuff then me and can back it up with technical data.

I am just a lowely Greddy guy . Hey, but I did do the install myself!

And yes, the Greddy has proven to be very reliable so far. But you will never get within 80 whp of 400 with it.

 

I think you get get close to 350+ with the basic in-line kit or and a bit more with the full race stage 2 kit. The SC will also get you around the 300-340hp range. At 400hp you need to start going outside the basic kits and upgrade other stuff on the car.

 

If you're in a nazi state like California, you may want to get a supercharger because at least you can still mod it, but have a carb legal sticker for any troubles. I know a carb legal sticker isn't an automatic fix or pass, but it helps a lot.

 

the sticker is nice for the CARB people to sneak in under the radar...

 

To have torque or not have torque, that is the question....

 

having torque = having horsepower

Doesn't work the other way though
