Here's my question..

Why does it take so much money to squeeze out minimal hp for our cars? I mean you throw an exhaust on a camaro and its 20 more whp. wtf are our cars just so beastly already that you cant do much else? and adding a supercharger creates ~50whp for a gt correct? Well why can you supercharge a stock 4.6 litre mustang and gain 150whp. And dont say you cant ive seen the tests and numbers. So what gives???
 


rmm more cubes=more power from mods..you are flowing more air, the more air you flow more power you make.....the more cubes you have the more hp you will make by adding or freeing up air flow..maybe..I could be wrong!
 
this cannot be a serious question. do you know anything about cars?

EVERY car is different and takes different thing to make it run right. most of the "performance" cars out there are made a little on the conservative side and with a little tuning and extra parts they can be monsters. a grand prix never was and never will be a "performance car".
 
I suppose so...but still its pretty gay lol

Also there is more of a NEED for the air flow......as in the stock cfm intake of our car is not as much as an ls1, and well the actual intake system flows the same (theoretically) well since the ls1 car NEEDS more are to feed the cubic inches we have it is choking it down more than a smaller motor.

well I do know a bit about cars but im not a self proclaimed guru, *cough cough*, and you think our cars arent conservative? Um u-bend, 107mph speed governer? And if this was an economy car it wouldnt have a 3.8 litre v6. Most people who dont know alot about gm dont even beleive they made 6 cylinders that big....so please explain to me the intermost workings of our cars bio, and why they are so restrictive. Cause youve taken abart a 3800 right? lol
so how about a serious answer
 


a) the car didnt come stock with an intercooler and the blower should be renamed a "heaton" because the efficiency of our blowers is just moronic.

b) the u-bend has got to be the stupidest idea on the planet

c) the horrifically low compression ratio these cars come with is just stupid

d) the car n/a makes 180 hp at the crank. you NEED boost to make these cars fast. that being said, there are only a few ways to go about it.

e) the car was purposed to be a family sedan with a little pep, in stock form they pushed the car nearly to its limits which you can see how the car knocks from the factory


do i need to go on? our car wasnt meant to be made fast or make big power. the cars youre referencing to, a camaro and mustang, are made to be fast cars.

Depends on the car. Dollar for dollar mod for mod our cars are actully pretty good and cheap to do if you stay away from places that have huge markups on simple **** (ZZP for example). There are many who will agree with me on this too. These cars are a hell of a lot cheaper to build that many out there. Theres a good reason why I still play with mine than my LS2 sitting in the garage. Not to mention, these cars can be had for CHEAP. I wish this option was availible to me back in high school, I would of had the fastest/cheapest car in the parking lot.

I think you need to do some more shopping and compare some prices. You'll be surprised what you find. GP is a good back for your buck. A good built tranny is pricey, but compare a built tranny/rear end on a RWD vehicle the prices come pretty close in the end.


I mean you throw an exhaust on a camaro and its 20 more whp.


Depends if its an LT1 or LS1... I will say an LS1 F-bodies exhaust is way more restrictive than ours even with a u-bend. I can see a good gain there. Start pricing a full exhaust and long tubes on one of those, quailty ain't gonna be cheap I'll tell you that.


Well why can you supercharge a stock 4.6 litre mustang and gain 150whp. And dont say you cant ive seen the tests and numbers. So what gives???


150 WHP? Ummmm, I kinda doubt that. And if anything it wasn't on pump gas, it was on race gas and the boost turned up high. And not to mention all the supporting mods too such as headers/full exhaust, fuel pump, injectors, etc etc. Not as cheap and easy as you make it out to be. Yes i've been around a Pro-Charged 4.6 before too, takes more than just bolting on an S/C. If it was that damn easy, the grave yards would be full of more teens.

Argue with me all you want but the fact of the matter is, dollar for dollar mod for mods these cars are a real good bang for the buck. Especially for how cheap you can get a hold of one nowadays. Oh well, I don't know anything anyway :th_winking:
 
Dollar 4 dollar mod and hp wise im with iron indian its not bad
Hell if i wanted to squeeze any real hp gains out of my Crown vic im looking at 3x more money then what ill have in my 98 gp

ANd yea thats comparing apples to oranges bu Im actually impressed with the hp to dollar ratio with these cars considering they were never ment to be performance cars
 
These cars mod cheap. No complaints here. If you want to get technical go dollar for dollar not mod for mod.
 


Compression is low because the entire thing is made of iron (block and heads) If you look at the engine powering the new cobalt it has aluminum heads which allows for the higher compression they run. Look at the high feature 3.6L V6, all aluminum with a compression ratio of over 10:1 combined with variable valve timing means more power.

The entire engine is an ancient design hence needing boost to go fast.
 
Hell I barley spent any money modding my gtp. I shopped around and found almost everything used on craigslist or ebay. I've got the mods n my sig and I MAYBE spent $500. Pulley,wires,cai everything. And the aftermarket for these cars is huge consifering its a family sedan type car.
 
Dollar for dollar ya it's cheap but mod for mod I don't see huge power gains


I donno about that. Its not that hard to make a 12 sec pass out of one of these. Depending on the route you take you can do this without swapping the cam too. Some cars it takes ALOT OF MONEY to run high 12s.

These cars gain about as good as alot of other motors out there. These ain't LSX motors here.

Why don't you do a top swap or something to your STOCK GT w/ 3" exh? Otherwise go buy something that will gain a 150 HP with one mod (so you think) and be happier? :th_laugh-pointup:

You can't ***** much until you actully do some wrench work on your car, judging by your signature you've done absolutely nothing on this platform. Not being a dick, just being honest with you...
 


So true I have built up a few cars an lt1 helped with a couple ls1's and some ford stuff and mod vs hp gains vs $$$ the gtp has been as easy and as cheap as the rest

Dont really see your point on the mods a 2 ton family car turning 12's is impressive in my book
 
Hey I'm not saying any mod will make 140hp or anything. It was a simple question on why basic bolt ons don't add much power. And I intend on doing a top swap within the month.
 
And trust me I'd drop this car in a heartbeat for an ls1 car. But it's not practical for where I live. I needed a good looking fwd car on a budget and this is the best I could do.
And I've done repairs on here so put a check on wrench work. Sorry I don't have a few hundred bucks to spend on mods...
 
if you think your car is unfriendly with mods you should try my car. swapping the cams will only net me like 20 whp MAYBE.
