12.28 @ 117 mph 1/4 mile
#21
I think your 12.28 will be hard to beat without a TS or the old HP in a bottle. I do think it is worth sending your TB to Maxbore since the cost is so low and that definitely is a bottleneck for you. Even if you go from 75 -> 80mm I'd bet you would feel a difference.
I'm not going to beat that time.
Me thinks thundercat or JgaXkr are top contenders since AVOS isn't going to show his cards. As you know there are a few other twin screws in process of being installed, so that is why I thought you might want to get into the record books and hold the title for at least a little while.
I'm hoping I will get to the 12.8 mark while still retaining an eaton, but I'm not sure until I try it. Matt Moran ran a 12.4 still with an Eaton, so it has been done.
I'm all for some competition, but the TS simply outclasses the Eaton.
I suspect a gain of at least 35-40 HP could be had from a good set of ported heads with larger valves, then a little more 5-15 from minor exhaust mods.
What are the stock fuel pump flow rated at?

Well the the 4.2 was only about 30 hp more than the 4.0 from the factory. Maybe a little more with a twin screw. So whatever difference that makes at the track.
I'm sure I can go sub-12 seconds with an lsd and stickier tires.
Let's ask someone with a 4.2 twin screw. Oh wait...I don't think they take it to the track, lol.

Yup, I have all extra weight in the trunk removed: spare, tools, carpeting, lighter battery.
I'll be putting lighter wheels on yet wider in the rear with wider tires (10 lbs. less each wheel!). The 18x9 BBS Milans weigh 30lbs!!!
If this was a race car I would strip it completely. But since it's not, there's only so much you can do.
Under 12 seconds will not be a problem.

I found Hi Spec rotors that weight 10lbs each up front and 4.4 lbs each on the rear... thats nearly 30lbs of unsprung weight from the rotors. 1 to 4 ratio would make it 120lbs off your car.
I wonder how fast an '05 XKR would be in a 1/4 mile,since its lighter to begin with, with a twin screw, mods and lightened.

At the track? Hopefully soon. I haven't really even driven it properly yet, lol.
It's still the stock 3.06 gear ratio.
I don't know what the weak link is yet. Hopefully nothing blows up. Might get drag radials. I'll see how it goes with street tires and lsd first.
I'm ticked off because I did the transmission fluid change today and only bought 6 quarts but 8 drained out
And of course can't buy some more anywhere on the weekend.

I did 13.8 in 90 degree weather in Florida with street tires and terrible starts, 100% stock...
