What did you do to get there, and what is your mileage like.

Yes yes, I know that MPG and V8's don't generally go hand in hand, but I like the fact that my 400hp V8 gets better mileage than some of the performance 4 and 6 cylinders out there.

If I end up keeping/building the car, would be good to know whether or not I can get to 430+rwhp and maintain some decent mileage.

I manage to take my Stang from 360rwhp to 500rwhp and increase the mileage (outside of boost anyways) via lowering the compression and upping the boost. I don't mind taking a little MPG hit, but would be nice to keep it where it is.

If you're near the 430rwhp or above, or have experience with these cars and those power levels, chime in. I guess anyone is welcome to chime in hehe, but would be good to have the thoughts of people who have been there/done that.

Maggie is a good way to get there and retain or have better milage. I can't tell you that I have better milage because I drive like an *** lol but I have heard of it happening. Plus
The maggie will give you plenty of low end. Generally over 400ft lbs at around 3k or better with the right setup.

Maggie and a small cam net me 480, and when I can remember that gas is expensive, I usually get 20-21 mpg combined city/ highway

500 wheel in a 408 lQ9 stroker, still slow to me, and terrible gas mileage

Nitrous

Don't want to do nitrous as I don't want to carry it in the car or worry about refilling it.

Thinking cam, headers, maggie and a good tune will fit the bill. Just didn't want to see my mileage drop to 15 unless its a result of my left foot.

Thanks all!

I have headers, exhaust, CAI, heads, cam and springs, and oversized valves. City is bout 15 and highway is about 26 doing 70-75. It needs to be retuned tho amd i might be able to improve. Few mpg.

If you want to make power and get good mileage go turbo. If you want fast it will never be attainable N/A in this car(at least my opinion of fast)

well you can drop any sort of serious n/a motor into this car that you can afford, you just need a drivetrain to hold it all.

Absolutely not!

^This, 500HP in these cars just isn't going to be fast.^

You must be THIS tall to ride the ride .

Of course you can chime in.

whisler151

I'll be 430 once my engine gets back from SNL. You can STFU in the mean time.

jk...but seriously, I should be 430...

Well keep me posted and once you're there I'll let you sit at the adult table

Whats done to your car?

PS. I want a Raptor really badly, so you can always hang that over my head.

SVT F15O

LoL.

I dont know what failed, but something in the bottom end decided to stop working. Loud knocking and cylinder 8 misfires at a rate of 1000 times per minute.

My rebuild is pretty much stock specs but adding a 102mm maf and intake. With a new tune I should go from 420 to 430. If for some reason it's not, because of this thread I will make them get 430 out of my V.

The block of the new LS2 is at the machine shop...should have all the new parts in and block assembled by the end of May.

Rocking the Raptor while the V is down...
