top speed?

[question]

i heard the only reason the governer is low on the sy is b/c the stock tires aren't rated high enough...if you put z rated tires on is their a chip that takes the speed limiter off or raises it????

 

[BigAl...]

Most aftermarket chips remove the speed limiter but there is only one chip to buy and that's the Ultimate, Call Mike at AR Autosports.

Ive seen datamaster runs going as high as 150...and there was more left in her...

 

[ghostrider_85]

runs out of gear around 150, right?

 

[jwaller]

yeah...I think that was close to the rev limiter...

 

[Pittman]

I heard stock with the gov off and a chip they will run low to mid 140's. I would think its like trying to push a brick through a wind tunnel at anything above 150. How do they handle at the top end anyone know?? I havent found a good place to open mine up yet

I had mine up to about 115 and right around 105 or 110 the wind noise got pretty intense and you could feel that thing hating the wind.

Competed in the Big Bend Open Road Race in Texas with Dabney in 1999. In his fairly stock Typhoon - still had cat - side exit exhaust - prototype Ultimate chip . Some other basics.

We averaged 120 mph over the 120 miles. We hit a max speed on the diacom of 150mph - On radar at a different point they got us around 143 mph.

Have 30 minute Diacom files from the runs - somewhere...

There was some video from the race on the Sportmachines videos..

I thought someone (Ghettosled?) said if you maintained high speed like that, you would likely spin a bearing in the motor? Also I have heard that WOT in Overdrive (which I assume is the only way to run those speeds) can be a risky proposition. Can anyone qualified to comment on this help us out? I would just like to know for the record.

 

[jwaller]

I dont know about the bearing thing...dont know why that would be...but as far as the trans goes...the stocker is a POS to begin with but a properly built 700 can do WOT in OD all day......

Here's a quote from Brian H.

Unless you have a built tranny, you are playing with fire using OD for normal
driving where there is a lot of 4-3 downshifting. Your sprag will ruin your day
if giving enough chance. Use D for normal driving. You have engine braking and
your turbo is ready at all times. If you have a built tranny and a nice TC, you
can do whatever you want.

Damn !
