RE: are high 11's reachable with this setup
I have 3.73's in my car and no vibration. I have only had it at 115 so far, but so far no vibration up to that point.
YOu will have the power to do it in a lesser car, but your fat pig mark VIII will not get off the line fast enough. Its weight and torqueless engine hurt you. You have to cut very good 60ft times to get an 11.XX.
I have ran 106 in the 1/4 mile but my ET was only a 13.35. Most everycar I have seen run a 106mph at the tracks ran a high 12. THey were lighter and their 60ft times were a lot better. Remember HP is the measure of hp, and ET is pretty much the measure you getting tq and hp to the pavement. You car will essentially eat up a lot of tq with its massive weight.
Due to aerodynamics and some other factors I can usually keep up with faster (ET) cars on the highway from most any mph roll.
At the track is a different story. I loose a couple car legnths off the line jsut about everytime, so I loose the race.
If you want a fast street mark VIII, you had better have a lot of spare cash, not be scared of borrowed power "NOS", or chop and strip it to pieces to where it is not as driveable.
If you want a car that can be modded easily and made lightning quick go buy a supra, mustang, or F-Body. A mark VIII is not a good start.
you had better have a lot of patience and money to get your Gen 2 to run an 11.XX. Without Nitrous to help you off the line you will create a lot of headaches for yourself.
If you want to run a 11.99, I suggest 4.30's, drag radials/slicks, headers with full exhaust, intake swap, your vortech SC with only 10psi so you do not have to change your fuel injectors and MAF, and a 115 shot to get your car out of the hole. I think you could hit 11.8 with that, if your engine runs decent right now and you have a really cold day.
What 1/4 mile times are you running right now anyway? low 15"s?
