The best muscle cars that are legends in the 60s and 70s had no more than 425 to 450 horsepower. This car is 486 with active exhaust, a full 500 in my Dark Horse. This car would have been legendary had it come out in 1968. It would have absolutely trounced any muscle car. I have published...

I am pretty sure if you add a Whipple Stage 2 or better it will do this at any legal speeds on your local roads.

It wasn't "at speed." He was, according to his own estimation, around 4 seconds in. I doubt his estimation is accurate, but, even if it was, his Mustang takes more than 4 seconds even to do a 0-60 run in perfect conditions. Yes, these cars will get a little sideways in Drag Mode "at speed."...

Africa? Where are you going with it?

Your Dad needs to be slapped, hard. First for getting a 15 year old a car like this, and again for encouraging you to pull this stunt on a public street last night. Since your Dad is not responsible enough, then you should be aware that racing in Florida is up to one year in jail, a $1000...

See earlier video about 5 minutes in . . .

Hmmm . . . His video four days earlier shows a 418 horsepower number on 93 . . . His baseline for this video is 406 . . . :curse:

He said he did that "this morning," twice, but it does not say whether it was before or after the baseline. He did say it "made no difference on the dyno whatsoever." He does not say.

How long did you own them? The heat exposure supposedly can damage the paint over time. Heat rises.

LOL I have a gravel driveway . . . I drive very, very slowly when I get home. I was very impressed with them at the track, though.

The thread will still be here after two days for folks to post results.

Whipple with methanol injection (wow, I haven't see that used on S650s - feels like 1990s) Very short video without a lot of information, title says 950 whp

I am not seeing much in the way of tuned Whipple cars since tuning came out for the S650. Please post them here, along with noting things like fuel (93, E30, E85, something else), headers, and other mods (pulley size if you know it). I would have thought the forum would be flooded with them...

I saw it and thought I better post a thread so others could post results. I am sure there will be more. Almost 30 horsepower with nothing but fuel change and a tune is nothing to sneeze at. I imagine it will go higher with headers and free flowing intake and more tuning.

28 horsepower gain on an otherwise completely stock car with no other modifications.

I thought the Nitto tires were for trying to get a launch without using a drag slick. I also thought RTR was a track focused sort of car. Are drivers running Nittos on road course track days?

What kind of tires are those?

1 7/8 or 2 inch headers are bound to add power naturally aspirated or boosted.

Maybe something is lost in translation, but my post was strong praise for your work and results. I do not have any suggestions and would have been scared to death to try what you did to your car.

That is some hardcore DIY
