v6 vs import 2 liter

your underestimating the v6

And you're overestimating it. If you think your stock V6 with nice powdered metal con rods, a cast crank, small 2-bolt mains, and a thin wall block will live reliably for a great length of time at 400 RWHP, you're flat out wrong. If it were that easy you would see a few more people buying V6's, bolting on turbo kits, and making an easy 400 RWHP, don't you think?

3.8 liters are good engines, the super coupe engine put out 260hp and 330 trq stock. Thats pretty good and I think were only boosting 9-11psi, with an overdrive pulley and an exaust they would pull 360 torque no problem and be able to keep up with just about anything stop light to stop light.

How a 4cyl can make more horses than a V6 is pretty simple, better tuning. The 4cylinders they use just have an incredible volumetric effiency compared to the V6 in the stang, meaning they most are 16valve engines with aluminum heads thats flow exteremly well, with a decent flowing intake and a half decent exaust from the factory there isn't much restriction. Plus if you factor in the V-tech motors they make now with variable valve timing that increases the output of the engine by a tremendous amount when under heavy acceleration by adjusting timing and fuel maps but then when driving normally it adjusts them for economy so they can get 30mph. Your V6 is good, but american car company have been known to choke thier car for ages, take the 429 for example, back in the day those engines had great potential and could have been the best but ford put a restrictive exaust as well as a intake on them. Peopel would get them throw hedders on the with a decent exaust and a new carb and intake and those cars would really run, so if you do the same to your car, IE catback(duals preferably) better flowing cats, headers, a throttle body and a CAI, you should be able to keep up with almost all of the 4cyl out there, at least the NA ones. And all of that can be done for under 1500.

Making 400 rwhp on stock internals in a new 3.8 is not possible. You would probabaly need to boost around 14-17 psi to acieve those kind of numbers unless an incredible amount of top end work was done to the car. The moment you came up on that much boost on stock internals your rods are going to have fun breaking through your block. Plus for 5000-7000 you can proabably find supercharging kit that will give you a forged low compression bottom end and from a decent company, not some guy making his own kit out of junk yard turbos and spot welded manifolds. 400rwhp is attainable. Just not very likely on a bottom end... you'll either bend your crank, chuck a rod, or burn a hole in a piston if your timing is off.

I don't know how much you know about cars..but theres more than just the engine. Okay, so you make 400hp. Cool. Now is your rearend/tranny/axles/suspension going to be able to hold up after you push the throttle to the floor a couple times? And yeah..like boosted331 said. If it was that easy to do..then why would I have spent $17,000 on a GT mustang when I could get a V6 for $8,000 and that turbo for $5,000 and make 400hp?

[TheStang00]

ok so yeah i probably overestimated it some... probably got a lil defensive cause i have one. and yeah i did consider that the turbo kit wouldnt be reliable for a long period of time, im not that stupid, i just decided not to mention that lol. yeah i also know about what ur sayin about that 429, they used a tuned version of that in nascar back in the day. i also understand the whole thing with ohv engines compaired to sohc and dohc. now after all that said, 5 grand could definatly get a v6 over 300 hp. idk why we went off on that turbo thing that wasnt the point. and that guy with the cavalier said he had 200ft/lbs of torque with a SC. comon i have more than that stock already. so that kind of just proved my point. also for a 2v head the 3.8 head flows extremely well. its loosley based off of the cleveland head. and one of u were sayin the STI has 300 hp/tq. well the price difference there is huge, i could buy two mustangs for its price. my point was simply that the bigger displacement makes for more torque easier. now the ohv design may restrict that some to where the I4 engines might catch up some but the basic fact still remains that the 3.8 is much bigger. thats one reason i personally am really excited about the new 4.0 v6 in the 05 stang because it is a sohc which will probably mean it has more potential due to better technology. and even though i may have overestimated it, i still think u were underestimating it.

[TheStang00]

and i dont know shit about the 400hp thing im not even the one that brought that up, the mark i was pointing to was 300

[neatofrito1618]

the mustang v6 and the gt is the same car. the only difference is the engine, they have the same rearend/tranny/axles/suspension.

Hey guys I am not lying here. I told you that I read on another forum(3.8mustang.com) that a guy had a custom twin turbo setup running 400rwhp on stock internals, and no pp, or anything. He does not seem to be a compulsive liar or dumbass, but seems to really know whats going on. He claims to have run over 15 dyno runs for tuning(which is where the majority of the power came from) and a handful of track runs. Check this guy out for yourself under the "Power adder" section of their forums. He really doesn't seem to be bullshiting, but who knows.

[I]"This is a stock 3.8 bottom end, no ported heads, stock cam. 93 octane pump gas. Through an automatic (higher losses than 5spd cars).

I drove the car 100 miles up to Reinharts in Jax so I could tune my car on his dyno. I was there several weeks ago but wanted to change my maf setup so it sampled smoother. Dennis has a Dynojet with some nice features, it has an extremely accurate WBO2, it can log boost and air temp.

I started out with no boost controller, the wastegates opened at 2900rpms and made about 9-10psi of boost, boost crept up to around 11.5psi by redline. After tuning the car made 351rwhp/373rwtq.
Then I hooked up the manual boost controller (ball and spring). With some tuning it made 399rwhp/434rwtq @ 14psi, at the higher boost level the turbos did not fully spool until 3400rpms, and held 14psi until 6000.

Engine temps stayed at 160 with the stock rad, intake air temps were ambient (65F) + 4 to 6* rise during the runs, the huge intercooler I built works great. 93 oct pump gas. Motorcraft AWSF-22C plugs gapped at .035, stock plug wires, stock ignition. 42lb injectors.

I will make another post with pics and specs on the Twin Turbo setup I built.

After I get my new Dynojet set up and make some tweaks to my fuel system I plan on taking things further. I have some little ideas that may result in making more power. Right now my fuel pump is on the edge."[/i]
I don't know about you guys, but I believe the man...

[dampachi]

Has he posted pictures of his twin turbo V6?

[Rod&Custom]

No, not that I know of, just those dyno sheets.

[dampachi]

Then it's possibly BS.

[Rod&Custom]

Right, I guess I would just like to think that it could make that kind of power(not that I own one). I check in there periodically just to read, so I will keep an eye out for more evidence, or better yet, pictures. I think I remember him saying that he was going to start selling them on there too though... can't remember, but will check back.

[dampachi]

Oh yeah, the V6 mustang has a 7.5" rearend and different axles that I know of. I'm not really sure about the suspension. But yes...they do share the TR-3650..as does the Mach 1/05s.

ya if u cant get 120 hp with 5000 bux then u must get ripped off everywhere a pick up a used vortech for 2gs and blaou ur there then throw in cams p&p chip exhaut BAM surpassing 300 o ya nos is only 500 bux now i think its safe to say u could be at 400 easily it could very easily be done
