Back in your corner!
Alfa,. can you make the equipment to make a SS achieve 180 MPH?

Well, RAB has near 700hp (I lost track) and HP does not translate to speed. Mix that in with aerodynamics that are worthy (to quote at fellow member) of a barn door and this is not a combination that leads to 180MPH. Not that I would ever challenge anyone but speedos are only accurate to 60 mph. GPS speed is the reference used in Europe.
Thank you! Not that I have to, but I agree with that. All vehicles have a "Wall" that no matter how much power you put through it, you are fighting so many things that there comes a point when that's it. I only jumped in to this thread to offer that 150s is doable, but how much more...I don't know.

We have been around in these forums together for a while. Aerodynamics play a major role, the USAF proved you could push a brick through the air with enough power with the F-4.
One could believe the Slinshot is not capable in theory with out trying to do it themselves or one could listen to those who have pushed them.
I for one have about 330 HP at the rear wheel and have accelerated through 140 more times than I should have. It happens really fast with 10.5 inches of boost.
Don't get me wrong, I don't believe 180 is attainable with our set ups. Especially considering on a dyno at max rpm 184 was made without an airload. -
Whatever the case, this is a really fun thread . I can dream 180 cant I ?

I started out working F-111s. Another sled with a gazillion pounds of thrust.

I love the Phantom.....

I guess I wont mention I worked on A-10 jet engines......

Loved the F-111s one of the best delivery aircraft ever. The drivers were also very experienced and never faultered. I was the lead targeting officer and talked directly to each pilot every night. Guided weapons were unknown. And lucky me went from SAC to Korea to Saudi. Glad I'm retired.

Guys I would like to add a couple of things here ....first I'm not sure why these guys are using a Speedometer when almost every cell phone has an application that gives miles per hour accurately with GPS also i've watched a 3000 pound race car lift off the track at 200 mile an hour and our slings way what 18 ,1900 pounds loaded ...even if someone were able to achieve 180 I don't believe that a sling would stay together and if it did I damn sure wouldn't be in it :-)...Just my thoughts....

A-10 jet
F-4, A-10, real war horses.

You guys are old - I'm not. Race you!
I'm just tired of BS and have no problem calling it out.

Gents, the Hero go cam is turned on at the start, includes the speedo and the GPS. Anything less is embarassing in Germany.

Mr Clean - you are one of the reasons I want another SS!

In aviation there are several model aircraft that have a wide variety of engine options. Although the higher hp versions on the same airframe will climb faster, carry more and accelerate better, there's very little difference in top speed.
At the speeds suggested here it's worth pointing out that parasitic drag increases exponentially. Double the speed and you quadruple the drag. 180 would have 9 times the drag over 60 causing the need for excessive HP to overcome the drag and rolling resistance.
You can plug in numbers on the site below. I used a high drag coefficient of 1, 11 sq feet of frontal area, 1900 lbs and 180 mph. Chart shows the need for 450 hp making this theoretically possible.
Calculate HP For Speed -
I remember them mentioning adding a startling amount of horsepower per mph to reach the Bugatti Chiron's top speed. I believe it's in here somewhere. Great show if you missed it.
