How much horsepower and what do you think the 0-60 time would be on a V6 mustang with minor modifications?

Question

the car has a Steeda cold air intake, dual exhaust with 2 flowmasters, a SCT SF chip reprogrammer with the 93 octane performance tune which also stiffened the transmissions shifts by 25% (can trip the tires when it shifts into 2nd gear). it has an automatic transmission. the car stock has 193 HP and the 0-60 is about 7.6 (i think). if you know what it is for sure please tell me. also if anyone knows what the top speed might be please tell me also. i also have 245/45/17 tires for beter traction which helps out on 0-60 time. thanks.

Answer 1

I have seen 7.6 0-60 floating around the net also, though I think that is for a manual transmission. Automatics are generaly .4-1 sec slower, than that of a stick depending on how efficent they are. I know the 05' uses a new tranny that is pretty effiecent and is said to be about .3-.4 seconds slower. So 25% of the worst case would be .75 sec slower at .5 sec slower it would bring you to about .375 sec slower. but just a guess. By guessing I would say exhaust maybe good for about 20hp, cold air 10-15hp, and rretune maybe 15hp? So just say that all that added in best case you got an extra 50hp over stock, I would gues you to be just under 1sec faster. might put you in the low 15, high 14 sec 1/4 mile range. and a 0-60 of say 6.6-6.8 seconds...Only guesses..But probably pretty close. But I have seen some reports of autos running mid 16's in the 1/4 mile and that would be more like a 0-60 of 8.3-8.5 stock...but I cant say if that is true or not. But if that is the case then I would expect you to be running more like a 15.6 1/4mile with about a 0-60 in the 7.6 range.

Answer 2

You have 3 choices Choice 1 Keep it as it is and be satisfied with what you have. Choice 2 Spend lots of money on the trendy do noting bolt ons only to see very marginal gains. A cold air kit is an expensive piece of eye candy that will give you about 5 HP or less. A cat back system is even more expensive than a cold air intake and you will see less than 5 HP. A programmer doesn't do all that much either. Maybe another 5 HP. By now you have spent about $1000 and gained about 15 HP if you are lucky. You would hardly notice a measly 15 HP. With these parts you may also void you factory power train warranty. Anything breaks and it could very quickly get blamed on your modifications. Choice 3 Trade this 6 banger Mustang in for a Mustang GT. The GT also has superior brakes, suspension, and tires than your base model Mustang making it a better all around car. The GT will out accelerate, out stop, and out corner a base model Mustang. You would need to spend thousands to bring a base model Mustang up to the overall performance level of a GT. In the long run it would cost you less money to just trade your base model in for a GT.

Answer 3

Your info was for a GT with a 4.6 I believe.

Your horsepower stock was 145bhp if it's a 94-98, 190bhp if it's a 99-04. I couldn't find any 0-60 times.

I hate to tell you, but the mods are pretty much pointless, except for the reprogram. You have a dual exhaust, but you're still using the stock exhaust manifold and heads which means it basically doesn't matter (except for minimal gains of course). An intake also helps only a small bit, because your intake manifold/heads are only designed to breathe in as much air as the stock intake would allow. It has to be ported to fully take advantage of this.

You probably have about 20hp over stock altogether, with either engine. I figure 10 for the chip, 5 for the intake and 5 for the exhaust. Don't say "The box my intake came in said 15hp gains" cause the box always cheats you. Those numbers were with modded engines; they put a stock intake, then put the good intake back on and measure the gain. Of course a 250hp engine is going to see a huge gain when you take the intake from a 150hp engine back off and but a higher flow one on.

They're good cars though. I had one myself and it lasted a long time before I finally blew it up. What I'd try and focus on instead of paying 300$ for a 5hp gain is getting some weight off of that heffer. They weigh about 3800 pounds, and if you can manage to shave 500 pounds off of it then you'll really be able to feel a difference in acceleration. The car's handling will also improve as well as braking.
