ok my dad has a 2009 pontiac g8 gt which has almost 375hp. him and i have always had a big rivalry and i told him (which i probably shouldnt have) that one day i will be able to beat his car with my gt escort lol. i started doing some reasearch and found that his car has a 10.5:1 power to weight ratio.. that means if i can get my gt to weight 2000lbs and get to 200hp as well as new tires and such i should be able to beat him... anyone know the best way to do this and is there any way i can do this with bolt on mods? cams and things are ok but i would prefer to not take the engine out to do so...

Start weighing the car's parts, make a note of what can be replaced with a lighter piece. I did that and stripped about 300 pounds off my car's weight. Yes, it made a difference, especially since I have, at most, 100 hp under the hood. As for the power, either go with a home-brew turbo, or do an engine swap. Don't forget the amount of torque that G8 has. It should get a good launch due to it, as well as being rear drive. He'll be taking off while you spin your tires, unless you launch easy. It's even more of a balancing act with high powered front drive cars vs. rear drive. If you really want to spank him, just save up the money, snag an Escort Cosworth, and make him eat your eternal dust. Go go YB engine.

ok yes a turbo would be nice as well as getting a cosworth... but im looking more realistically. i would like to stick with the stock engine and leave it naturally aspirated. meaning no turbo or nos lol. whether i lighten it up a lot or get the power i want 10:1 power to weight ratio in the end. how much power do you think i could get with building the engine, meaning cams pistons intake exhaust ect...

With my GT, all I did was put an intake on the car and was able to beat a volvo that was dyno'd at 135rwhp. And it wasn't one of those "wow that was close" I was at least a car length ahead before he stopped trying.

You're going to need ~230whp to get that 10:1 ratio....

You aren't going to get anywhere close to that with what you have listed.

If he strips weight to 2000 pounds or less, he won't need as much power. Of course, by then, he'll be driving a sheet metal box that won't get the girls (but he'll be able to pull away from them).

He'll still need ~200whp.... :D

He'd have to strip to like.... 1500lbs with him in the car to make his plan feasible. Not going to happen.

You want to beat a 375hp car with just weight reduction and you are asking people to be realistic when they suggest turbo or nitrous? I dont even think nitrous would be worth it, if you want to beat it just get a new car, you shouldn't have made that bet. Taking off your interior trim pieces or a/c compressor, or carpet, or back seat is going to have minimal effect. Plus what happens when you beat your dads car by a bumper, and at the end of the day you go home and pull up in a fully gutted car, then what.

Not trying to be negative or rude, but realistically its just not optimal. If someone told me they could beat my mustang in an escort I dont think i would be able to stop laughing, turbo or nitrous, and I dont even make close to 375hp.

Are you guys on crack lol The only way you could "possibly" come close to 200 hp n/a is with the stoker kit, im not even sure if that will get you there, and hed need head work to go with that. g8s trap about 108 in the quarter and run a 13.8. Turbo is the only way to go, a gtx setup with corksport downpipe crank up the boost, and you might be able to keep up with him. And a gtx setup is basically "bolt on". and if you have the exact same power/weight as him you'll probably loose, hes got the traction and poweband advantage.

and nicko there are a few escorts on here that would leave your mustang in the dust.

Ciento, this is a GT escort that the OP is talking about. UnexplodedCow is just a CVH fanatic (no offense meant!) and is just saying that making 200whp in a CVH is a piece of cake, but not with the mazda bp, not without some kind of boost at least.

Ah gotcha.

I still maintain that nitrous would be the quickest and cheapest way....

75 shot and some straightforward weight reduction and it might be a race.

Look at the UK 1.6L cvh powered N/A Escorts...they're making ~180-190 hp, and they have less displacement. It can be done, but it would require replacing almost everything but the block and head (and of course modifying those, too). For the price one could build a turbo CVH that would make north of 300 hp, in a more streetable tune.

Thats funny you make a statement like that if you dont even know what kind of mustang it is or what it has done. Show me some, I dont need 375hp to go high 11's, but entertain me. Those gt8's are probably tanks, and the fact that it traps 13.8 at 108mph shows that it gets no traction at all, you should be able to get mid-low 12's with that much mph, before I built my motor I went 12.9 at 101mph on slicks w/ 1.7 60'.

I am not trying to make fun of anyone, but I come on here for information on my daily driver, not to see how I can make it into a race car because its not.

ok everyone makes a good point. my car is front wheel drive and his is rear and to get the weight i want i will have to strip a lot of things. i already have the back seats and panels gone and lightweight carpet covering it up to help with the noise. i also took out things like the spare tire, windshield washer tank, everything having to do with the a/c, including all the lines compressor condensor everything, as well as all the inner fenders and other unnecessary things. my dads car weighs around 3800 pounds and i want to say has 300rwhp with the tuner he has. that means he has 12.7:1 power to weight to the wheels. that means if i can get my car to 2000 pounds i only have to make around 170 to the wheels to have a better ratio than him. if the madza motor that came in mine came with 130 engine hp how hard could it be to get up to 170whp? if i got an intake, injectors, a mild cam, a good ignition system (msd ignition box and coil) and a full header back exhaust and little things like that i should be able to get that right? the only thing i need that he has is some sort of lsd.. i have been trying to do some reasearch to see if any mazda with the same trans came with an lsd. how does this sound???

by the way i take my car every weekend to the friday night drags and i can stomp a v6 and stock v8 mustang. just a little info lol
