what might be a realistic zero to 60 guesstimate
what might a best zero to 60 mph be for a BDR equipped with a Roush 342r I realize a lot would depend on the driver and conditions but just trying to get a realistic idea.
also does anyone know what the actual weight of the vehicle as equipped would-be? Thanks |
Weight will be around 2600. There are too many varaibles to even give a guess. There is a equation for 1/4 mile time for a given weight and HP. That is about as close as your going to get without testing the setup. A safe guess would be under 5 seconds, it could be very under.

Hi D111
If you are not able to "go live" - try this formular: http://www.stealth316.com/2-calc-hp-et-mph.htm Remember to add weight of driver and that the HP is on the wheels... BUT... In the end the tires (spinning) and you ability to shift gear will be the biggest factors ;) |
Your 0-60 times will be traction limited, but figure around 5 second. 12.5 second quarter mile at a 114-117mph range, again street tires and traction limitations will vary.

thank you guys,just wanted to get a realistic idea, I don't want to be talking out of my ass about my new baby:)
Looks like this guy is putting it down pretty good. http://www.youtube.com/watch?v=LqjMcKW0FTE&NR=1 |
I would think because of the lightness of the vehicle the zero to 30 would even be more of an advantage.

But once you hook up you are flying (if you can keep it straight %/ ) ... with a 342r and if you got lsd, I also think just shy of 5 sek is possible - if you are looking for the best time you must add sticky tires. |
If you can do 4 or under, thats when the BDR half shaft snaps. :)

The BMW half shafts are to provide the best road handle. :cool: |
Depending on the final drive ratio (rear gear X 1st gear ratio= Y) I think under 4 is possible with a small block? The BMW half shafts are apparently weaker than other typical IRS units found in Cobras, as far as torque rating is concerned. Jag, Ford, Kirkham/Shelby style, etc. are stronger units.

Enjoy the drive. Adding to that, the driver that put the 3.4 down was not a pro driver or hired gun... it was actually the truck driver of the BDR show rig! |
I've seen the roush 402 on a bdr do 4sec to 60. A 342 wouldn't be much slower to 60. Based only on owners descriptions of how their car launches, I think BDR grabs better than some replicas, the common FfR and SPF. Squat and go on Goodyear f1s.
Standard 315s help Here's one about 4 sec. http://kitcar.automotive.com/92067/0...omponents.html |
Sub 4's 0-60's are possible with small block BDR's

I have hit 3.6, 3.7 and 3.8 0-60 times with the older style BDR half-shaft with no problem. Also, I have made over 20 hard trips down the 1/4 mile with sticky drag radials and had no issues with the half shaft. Yes, sub 4's are possible with a small block, easily and repeatedly. My car was build in 2006 and I'm still on the orginal half shaft. I was worried when I read everyones opinions, but opinions, like the one above are no match for real world testing. BDR makes a fine product, cabable of handling tremendous abuse. |

Are you running the standard rear? So you mean to tell me that there is a chance that my car stands a chance of not getting spanked against my friends new ZR 1, that he just paid $115,000 for.:eek: Dennis |
Dennis,
Don't take this wrong. I hope that you are getting a Cobra because you like them. With this last post and some of your other threads, it seems to me that you are getting this car for all the wrong reasons. If I am incorrect, I do apologize. |

No offense taken, but please explain. The reasons I believe I purchased this roadster . I like Harleys but I don't like the thought of my flesh scraping against the pavement. This seems the closest thing to a Harley-Davidson with less risk. they always caught my interest even though I rarely see one in New Jersey on the road. I'm going to be 52 in April if this was 20 years ago it would probably not be a good idea, but now hopefully I will not get too crazy with it. I stopped at the Harley-Davidson dealer today matter-of-fact to pick up some s100 wax and leather treatment,and feel that I made the right choice risk wise. Bikes are just too risky here in Jersey lost a couple of friends over the years . Dennis |
Standard, except for tires
Against the ZR1 in a 0-60, yes - you have a good chance. The 1/4 mile is another story, it eventually becomes a hp race and the ZR1 is tough to beat unless you have some big power, they are running 10.9's on drag radials. My car is a run of the mill 392 stroker with GT40 heads. You can only get so much power to the ground and 450hp is plenty to get 3.5 seconds to 60, I'll need to spend some money on new heads and nitrous to get into the 10's. I ran my 0-60 times with Nitto NT05R drag radials - not slicks... and lot's of practice.

do you have a posse rear?

I stand by that statement, if offends BDR folks, well, the facts speak for themself. FACT is, you can find more threads and instances of broken BDR half shafts on Club Cobra, by far, than you can of other replicas. Possibly, more BDR half shafts failures than ALL other replicas combined! So, they ARE, in fact, "apparently weaker" based on the threads on this forum. Or, the BDR "apparently" has more traction than the typical replica? Or, (insert your reason/excuse here why they break_______________)? |
