I hit 110 in my NA roadster yesterday in the mountains. I could easily have gone faster but I ran out of trucks to pass and passing lane at about the same time.

 

 

That sounds right, they were electronically limited to 158. This can be turned off with a tune. The modified SRT6's can do a bunch better but are still limited because as sweet as it looks the drag coefficient is not as high as say a Ferrari. I love the style of our cars and would rather have the looks over being able to go a few mph faster. Nobody would drop by to chat at 180 mph.

 

The specs claimed the N/A is limited to 150 mph and the SRT6 to 158 mph. I can vouch for an alleged 140 and 150, respectively.

 

125 cruising for about 15 or 20 miles on a 4 lain divided back Hwy in Alabama at about 6:30 on a Sunday morning. No float, no sway, solid as a rock with PLENTY of room left to go.

 

I'm curious...do you guys think the rear spoiler has a significant effect on stability at high speed?

 

Yes, it does. One interesting fact: According to the Chrysler engineers, the NA's extendable spoiler has just as much downforce as the SRT6's fixed wing! The discussion with several of those involved can be found on YouTube and if I remember correctly the downforce was a couple hundred lbs.

 

Broke the double ton once but was back in the '60s Few cars are stable past 150 and best not pass a VW going the other way on a TLB when close (don't ask). Part of the spec on FHP Dodges back in the day was 140. Had 3.31 gears in the E-types so faster than later cars with 3.54s (big DOHC 6s would go 7,000 rpm. Once.)
As to current limits think the lowest top end on any of my cars is probably a touch over the ton with the Jeep (barn door etc..) but these days am more interested in 2k at 70 mph. Did remove the 125 limiters on the Reattae.
US cars are required to be limited to the speed rating of the OEM tires.
Personally liked the 85 mph speedos. Below were easy to read. Above was watching other things. Had the one on my Sunbird wrapped all the way around and back to zero once.

 

This post might be interesting if I knew what the initials stood for.

 

Tlb is two lane blacktop i believe

 

Fhp is florida highway patrol i believe

 

Ton is 100mph, double ton is 200mph i believe

 

DOHC is double overhead cams
6s are 6 cylinder engines
RPM/Revs is revolutions per minute
E-types were a Jaguar model
VW is VolksWagon (People's Car)
3.31 and 3.54 were rear axle ratios (e.g. 3.31:1)
Reattae are more than one Reatta (I have two)
US Estados Unidas
OEM original equipment (from the) manufacturer.
Speedo - speedometer: at one time during the double nickel US cars were required to have no more than 85 mph speedometers
Rest are correct. TLB is a great movie.
Sorry for posting in gearhead. I do not think in language & have to translate.

 

TLB = The Lost Boys ???????

 

lol...lol some more

 

So...what car did you do a double ton in, in the 60's???

 

GT40. Fortunately am 5'10".

 

That's awesome, i would love to drive or ride in a GT40, even the newer ones.

 

I just grew up with strange cars, mostly European. Friend bought a 289 Cobra for $1995 off a dealer lot. About the same time I bought a Devin-Jag with one of Norm Latham's blowers but since took the cure.
