Respectable modification?

[black pearl 5976]

I’ve a 1997 svt cobra with only about 70,000 miles, her only modifications are 4.10 rear end, lowered suspension a tune and wheels. Completely stock aside from that I would like to know all that is to know about this beautiful piece of art especially for maintaining peak performance currently the engine is bone stock n/a down to the factory exhaust manifolds and all, I was blessed to find this vehicle and as my choice daily driver I would like to know about reducing her carbon build up and prolonging the life of this beautiful beast and I must admit I have been shunned for directly asking about emissions and how to make it run right when I started the engine swap into my 1997 mustang gt of replacing its 4.6 sohc. My goal is to improve gas mileage I already decided pro charger if I'm intended for forced induction but my biggest goal over gaining power is improving gas mileage and efficiency.

Someone must be an english major.

There isn't some magic trick to gaining a bunch of MPG. It's all about the maintenance. Such as good spark plugs, clean the air filter, make sure the MAF isn't gunked up. Headers and exhaust might help and a decent tune might get you a couple MPG, but I wouldn't expect to suddenly go from something like 18mpg to 25mpg. These cars just aren't made for it.

Complete emissions delete really skyrocketed my sohc mpg but everything you speak is very true and much appreciated

If deleting the emission stuff gained you a bunch of mpg then something was failing or had failed. My current car is (allegedly) missing it's emission equipment and it's getting the same mpg it got when it was an upper only eaton with everything in place and working.

Want better gas mileage? Buy a fuel efficient car or throw in different gears.

Can you please stop talking about emissions. Do what you feel is necessary to make your cobra the best it can be

I mean.. no

You can lean out the fuel trims and get 30mpg+ for sure, bone stock they get 25mpg highway all day if you keep it under 70mph

I've seen a 400hp corvette get 41mpg with the 6 speed

Buy a Procharger, it should bump you up from 17mpg to 30spg.. that's all that matters.

I’m only seeking knowledge that’s been sadly covered up

 

[CobraBob]

"Knowledge that's been sadly covered up"?? What are you trying to say/imply?

 

[DSG2003Mach1]

these dont have carbon buildup issues like something that only had a direct injection system. The IMRCs can get gummed up but thats about it.

4.10s and boost are not going to help with fuel efficiency - your right foot is the biggest determining factor on that one.

as for the rest, I dont think anyone really knows what you're referring to.

 

[Stalkerfiveo]

If you wanted better fuel economy, 4:10s weren’t the best option.

That said, if it’s a DD, do the MMR head cooling mod ASAP. My 97 Cobra is at Kurgan right now due to an overheated and failed driver side cam that caused even more damage when it completely let go.

Funny thing, when I went from 3.27's to 3.73's in my 98 GT the MPG went up. The consensus at the time was the shorter gears made it easier for the engine to keep the car moving. When I put 3.90's in my 01 Cobra the MPG didn't take a hit. At least on the freeway. Stop light to stop light was a lot more fun.

JMO, but I don't think gears are the MPG killer most think they are. Under normal circumstances at least. I'm sure going to 5.13's on a 26" tall tire and blasting down the freeway at 90mph might have a small affect on things.

 

[98 svt]

When my 98 was NA with 4.30s, I would get 20.5 MPG regularly when it was mostly highway.

Who gets a cobra and cares about gas mileage?

Yeah screw mpg it’s about smiles per gallon
