Default Going from 4.11s to 4.56s, how much can I pick up?

I'm currently pushing about 450 rwhp through a six-speed. With my 28-inch tires, I know the 4.11s I have right now will be a tad too tall. Realistically, how much am I giving up in e.t. by sticking with 4.11s opposed to going with 4.56s?

Wow, I don't have experience with 4.56 in an LX1, but I'm thinking that it might be too much gear.

ALOT! the t-56 has to tall a first gear so we need as much gear as we can handle

You might gain a tenth (most of that on the 60 foot time) with the 4.56s, if you can get traction.

I changed from 4.10 to 4.56 last year. Gained 0.1 s and 1.5 mph.
1-2 and 2-3 shifts come quick, no sleeping at the stick!

SlowLT1: I'm pushing less than 450rwhp. What's your trap speed and did you do the math to make sure you won't be bouncing on your 4th gear rev limiter by the end of the 1/4? If that's not a problem, I'd say "go for it."

The 4.56s will be good for 130 mph, and I don't plan on going 130 mph
