Default All these scary Cobra Stories....

Hi

So I had a quick question....

This is the first week I have gotten my plates on my Cobra and have actually driven it out and about. I put 160 Miles on it this week and it has been totally fun!

My engine setup is a 521cu (eagle stroker kit, ford aluminum super cobra jet heads, flat tappet cam by cam research, edelbrock performer RPM intake). I also have the holley 950 fuel injection setup, msd 6A ignition, tremec t56-magnum, and a tru-trac differential with 3.5:1 ratio. Tires right now are cooper cobra 295/50/15 back and 235/60/15 front.

So...the question!

I see these threads about people breaking tires loose at 60 mph and going sideways/etc.

I had my cobra upto 85 mph (it got there very quickly!). I have been able to start in 1st gear and go upto 5th gear. Granted I was not going to WOT as I am trying to get the feel of the car.

I have been normally starting now in 3rd gear and shifting to 5th. With this combination, I have pushed the gas to probably about 3/4 of the way. It pulls very hard. My buddy timed the car from 30mph to 70 and it took about 2 seconds.

So what is the deal with all this tire smoking? I want to avoid breaking my tires loose at 60-70mph and sliding sideways into a tree.

I don't plan on making any 90-degree turns and hammering the gas either.

Just curious on this and looking for "safety" tips.

Although...once I get about 300 miles on the cobra. I DO plan on starting in 1st gear and slamming the gas. But it nice open area

thanks in advance
