NO PERFORMANCE GAINS ACHEIVED WITH MOST MODIFICATIONS

Now that I have your attention:

IF YOU ROUTINELY RACE YOUR CAR THEN PLEASE DO NOT READ THIS THREAD OR REPLY AS IT DOES NOT APPLY TO YOU!!!

A V6 2010 Camaro has around 304HP
An SS 2010 Camaro has 426HP
A 2009 Pontiac G8 v8 has 361HP

WHY do we spend big $$ on a small 8-10HP gain from a catback exhaust, cold air intake etc.. that will increase our overall HP FARRRRR less than the simple difference in HP gain from a V6 to a V8?

The Horsepower between the cars above varies more than 120HP and yet the performance of each of these cars varies only by tenths of seconds in a quarter mile and maybe less in a 0-60 run. (WITH OVER A HUNDRED HORSEPOWER IN DIFFERENCE)!!!

These modifications look good and sound good, but there seems to be no actualized difference in the cold air intake performance in real life. Although I VERY much appreciate the science and time to test the products!!! Great JOb!

I'd say buy your aftermarket stuff to personalize your car and enjoy it! Take Power gains with a grain of salt. Buy the CAI that looks cool to you and the exhaust that sounds good to you and don't worry about the numbers!!!

If you want real performance gains: you'll have to get a turbo or supercharger or some other extreme engine modification.

Any comments?!

After trying to fully absorb the CAI results thread (http://www.camaro5.com/forums/showthread.php?t=48202) my understanding is that the CAI by itself doesn't do all that much dollars per hp but instead opens the door to fully utilizing other mods down the line (long tubes, hi-flow exhaust, even forced induction). The stock intake will eventually become a restrictor plate once other things are added to the engine's "respiratory system". Now I could be totally off base with this but the CAI seems to be the first logical step in fully exploiting what the engine will eventually be capable of.

Let me guess...you're keeping your car stock?

I dunno...you can pretty easily get 50hp without any major modifications (intake/headers/tune)...50hp is a difference that you can feel. Right now I just have a Vararam and a tune...and it's made a HUGE difference "in real life".

Exactly...and adding to your list a cam..is not considered an extreme engine modification either

CAI, Exhaust, etc really are not a huge bang for the buck.

This is why when you read that gears give you the biggest bang for the dollar. They will make you feel like your car gained 50rwhp easily...

CAI or headers work to make the engine take in more air and gas and the more that can go in and out of the motor the more HP you make, there is good headers and some not as good its the same for CAI and with some you need to do a tune and some you don't.

If you go to a NHRA race and see a top fuel car run that car uses 8+ GL of fuel for 1 pass down the track.

Did you see the post on the new sho. It ran a 12.92 with just a tune.

Properly matched bolt-ons and a good tune can easily gain 50-100 hp. People would not be spending their hard earned money if it did not. Things like gears are included here.

It does cost more money, but a Procharger is also a true bolt on. No pulling the intake or anything like that. Easily done in a day. Magnacharger is not much more difficult either. But with FI mods you really want an updated exhaust to maximize the increase.

In my mind nobody make a car fast enough from factory. 8hp here ,10hp there, I
would sooner have 444 then 426.

Unfortunately on a NA car, you're stuck with small gains that turn into a overall bigger gains. Ever hear the term "ounces make pounds"? Coming from a turbo car where you can just crank a knob and get 50+whp it takes a little getting use to but these are the facts. Add to it that you're getting the "almost corvette" tax added since it's such a new platform and it is a NEW Camaro. If you want REAL gains, give your new car a MUCH NEEDED diet and put it on the bottle. That will give you 100+whp for less than $500. It will still pass emmisions and won't void your warrany, if you take it off before taking it in. Unless i'm mistaken, there isn't a "nitrous" trigger in the ECU and it won't show up in a Tech II report.

I like the responses and still feel that unless you are going to (down the line) do some major modification (NOS, TURBO, SUPERCHARGER) which the VAST majority are NOT, headers and CAI may give you a few extra horsepower, but until you gain well over 100+ HP you won't see any TRUE performace gain (ie.. compare the V6 to the V8 in the 1/4 mile times...and that's OVER 120 EXTRA HP!!!!) 10 here and 20 there will only give you milliseconds... so unless you are a hard core racer...DO IT ONLY FOR THE SHOW, NOT THE 'GO'...

btw I plan to put axle back exhaust for better sound, but not any gain... but I'm not bashing anyone at all... spend! Spend! Personalize your car to make it kick A$$, (and stimulate the economy while your at it!)

PS... someone still needs to explain why 120 extra HP from the V6 to the V8 give only tenths of seconds in improved performance?

you can spend a few thousand on suspension and the car handles totally different...and the pest performance mod in my mind is a driving school...but anyway..I dont believe in NOS, turbo's or superchargers...but I do believe in more cubes head work cams etc...im a n/a guy to my core

Same for me no superchargers only big CI and internal mods.
