I had my 04 c5 coupe dynoed today. It dynoed at 293rwhp and 310 torque. Does these numbers sound low? Also what can I do?

 

Auto or manual?

 

Right about average for a stock motor.

 

Depends on a lot of factors. At Carlisle my bone stock 97 dyno'ed at 297 one year and two years later it dyno'ed at 298. Some of the newer cars were dynoing around 305.

Sounds good to me for a stock motor. If you think its to low
tell everybody you have 350 hp-just don't say where it is
measured from!!!!!!!!

 

Buy a Z06 --thats it--

 

Sounds right. To answer your question you can do lot of things. But once you start modding it tends to be difficult to stop.

Most add an aftermarket air intake, long tube headers and a tune and you will pick up 30 or hp to the wheels. From there you can do a cam upgrade and get another 35-50rwhp. Then you start needing a stonger clutch and larger fuel injectors, etc. Add some better heads and intake and you can add another 40-50rwhp.

Another route is forced induction, add a supercharger and get 500+ rwhp.

 

I guess ill have to start modding but i dont know where to start please help me

 

Start with talking to your SO about available funding.

 

Also, start making arrangements for a suitable alternate living location. You'll probably need it when you get kicked out of the house.

 

I love being single!!

 

What is a the average price including install for a good head cam package?

 

Agree if you are married buy a comfortable couch You can start with the basics...breathing in and out (air intake and headers w/exhaust)

 

For a stock A4 with 3.15 gears, those numbers are typical.

 

Welcome to the forum.

You will find a lot of info here - use the search functiion.

You can spend a lot of money modding your car.

Start with LT headers and a CAI. Find a forum sponsor to give you personal advise and they can install it for you.

 

Looks like fine numbers from a stock vette.

I always do the intake/long tube headers/exhaust on a car to free up those extra ponies. Then the real mods begin lol.

 

Do a lot of reading and buy some tools.

 

My 02 coupe with Blackwing intake and Ti Z06 catback dynoed 296 so your numbers sound typical.

If you're not careful, modding without a specific plan can cause alot of headache. Tyipcially, the idea is to think of the engine as a big air pump and the idea is to allow it to breath more easily.

The initial mods for most people are intake and exhaust (catback). Look to spend $200-$400 on intake and $500-$1200 on catback. Then you have to decide whether you want to go forced induction (supercharger or turbocharger) or motor only (head/cam work). There are advantages and disadvantages for each. S/C or T/C are going to start at about $6K and go up from there. Head and cam work can start at $4K and go up from there. There are tons of variables, but more hp means more money.

You also have to decide how far you're willing to deviate from stock street driveability. My car is my daily driver but I also frequent the local drag strip. So my mods have been focused on getting quick acceleration off the line and maximizing hp over short distances, but still be able to drive it around town and back and forth to work every day. To do this, I've gone to a higher rear end gear, added a torque converter to get higher up the rpm (and hp) band immediately, added a supercharger and blower cam as well as other mods. My car is way faster over short distance than it was originally (8.82 @ 82mph to 7.12 @ 98mph in 1/8 mile), but I've given up top end speed (175 mph to 155 mph on the dyno - but who ever needs to go that fast) and economy (26 mpg to 21 mpg). I haven't actually added up the amount of money spent on these mods, but even off the top of my head it's probably close to $12,000 and rising.

The other posters are not joking. Once you start modding, it's hard to stop. Speed and acceleration are addictive.

There are alot of great supporting vendors on this site that can help. But, there are also vendors out there that whatever they sell, that's what you need (if you catch my meaning). You MUST do your own homework. Spend alot of time on Corvette Forum, ask alot of questions, do alot of reading.

 

start with a plan of what your priorities are and modifiy accordingly. mostly daily driver track once twice a year, daily driver say 6 to 8 track visits a year, daily driver in frequently mostly for track purposes but can still get the groceries. im doing the thrid one now after having done the first two. pick one and youll get tons of advice or pm me with what you want to do and i will give you my sequence of modifications. i drive a 04 automatic. just did ten second passes on 11/5/08. the faster you go the more you spend
