Gen 1s are still faster

Getting a mite warm, a?
 
If one uses 5500 rpm (near peak HP) and calculates the top speed (in OD) for a Mark VIII with different gears...

3.08/198mph
3.27/187mph
3.55/172mph
3.73/164mph
4.10/149mph
4.30/142mph
4.56/134mph

;)

So 550 +/- more rpms would have resulted in nearly 50 mph more?

I don't remember if I turned the OD off though. (Probably not)

Your speedometer and/or tachometer is off? At 5000 rpm you should be @ 104 mph in 3rd or 149 mph in 4th.

What's your tire size?
 
I'm pretty sure the speedo is correct (at least around 45-60mph). I'm not sure how to test the tach.

Tires are stock size.

Sorry it took me so long to post. LOD wouldn't (and still will not) load for me. Our illustrious head moderator had to send me a link to get around it. Thanks again Sharon!

Well, I should be passing my NJ bartenders license test tonight.(Yes, here in the lovely state of NJ, even Bartenders have to be licensed!!!) So, the money will be a - rollin' in!!! Seriously though, I do plan to do this upgrade relatively soon. I am gonna buy the driveshaft first as it seems the most prudent course of action (especially after the vibration I'm already having; see my brakes and rotors thread for all the juicy details). As soon as I get all of the required parts in order I will contact you DLF, hopefully by then your offer will still be on the table. Like I said earlier, I enjoy the work (greasy make my car faster/better/prettier work) so I definately want in on that most gracious offer.
 
He does have a gen 2 ;)

HAHA!

I only hit the rev limiter once,,,, but I sure didn't take my hands off the wheel to take a pic!

Thats why you bring your wife along! I bet one of your grand kids would be floored if you said, "Hey, lets go for a ride in the Mark, I'm going to have you take a picture while we got 127 MPH!" lol!

If your curious SS, here is my write up of a drive shaft swap. :)

I think its right too... I hit 120mph at 5k RPMs in 3rd gear.

Since the threads somewhat off topic and compairing gen 1 and 2's... Which one's more aerodynamic?


I wonder what your before and after times will be after the gear change and tune :confused: Good luck :D
 
Thanks. I'll keep everyone posted. I have two job interviews over as many days coming up, (one at PSE&G!!!) so if I get either one this mod will be happening soon.
