I have had mine to 159 mph ( gps tracked). The car was still very solid ( aka stable). I think with the windshield removed, slight change to suspension and the right gearing you would get a proper Kirkham to approach 190-200 mph.
My Kirkam has a Shelby Aluminum 427 Block & Heads, stroked to 495 ci ( built by Kinetics ), 5 speed tranny and the Penske adjustable suspension.

105-110 in mine and that was sufficient for my blood and the situation. Car needs more prep and a better alignment to absorb more. I'm in awe of the old-timers that raced these cars back in the day. Confidence does grow with the conditions...think it through before you go stormin'. 
Good thread! |

I've had mine up to 135-140 down a relatively short front straight. Rev limited (I think at 5.5K, at the time), toploader, Kirkham 3.42 rear end. I've since upped the rev-limiter and will see what I can do at Thunderhill in July.

Boss,
You are my hero for making that drive to open house.
I saw 130+ on the same short straight that Igofaster mentioned, on the open highway, I haven`t looked at the speedometer at speed for too long.

RaceDeck- 159. Was it on the street? Didn't feel light? Tell us more.
I haven't driven much after the open house and on that trip I had my hard cover over the passenger side- I am looking forward to going that fast with out the cover. Thanks

Approximately 155-160.
Car was smooth.
I have a racing windscreen so that might help and yes it was on a track -- not the street.

Just out of curiosity, just how fast is the windshield and its support rated for?

tt,
I'm not sure if your question is in regards to the racing windscreen or the standard windscreen; however, I have had both on the car and at speed without issue. Actual testing and rating of either is not something I've ever seen data on. IMO the racing windscreen has less force on it and way more sheer strength on the attachments than necessary.

I like that.  You might also ask how many people here have shown off for a family member or close friend and then said to themselves under their breath, " damn, that was close -- I better not do that again...."  |

Speed is relative to the driver and the car. One of my fathers buddies raced at Indy a variety of times. He got so used to the speed that he could pick out a hottie in the grandstands every lap. She had really bright headlights too!

Yes I ran that particular speed on the track at Millers ( Full Track with the 9/10ths mile straight). My Kirkham handles superb at that speed, not lifting or drifting at all . The car feels really solid at top speeds as well as through the corners and on the street. I LOVE MY KIRKHAM

Actually I get nervous at anything approaching 130mph. Unless you have areodynamic upgrades beyond the original design I highly discourage +130mph runs...
That being said the race track at Summit Point's longest straight will allow about 120mph for a 615hp Cobra. So all is good with me.... Be careful if you go over 130mph as it feels like you are driving a dust mop.
As for my other cars, Aston, Lotus, etc... Anything past 150mph is a snap.

RaceDeck- Is yours set up to Kirkham specs? I used Kirkham street specs but lowered it 1/2in (actually that is the way it turned out and I liked the way it sat-so be it) My car weighs 2280 w/ iron heads & block. What does your car weigh?
