Replacing 3.55 with 4.09

[PowerAdderGT]

Proper gear selection is crucial to optimized et. As an example my 2000 GT with 252 SAE rwhp ran 8.10 in 1/8th and 12.76 @ 105mph in the 1/4 with 4.30 gears.

96-01 Cobras at the time were running high 11’s in the 1/4 with 4.56 gears and ~300 rwhp.

Whats next..5:13's? or not available for irs..

I believe for the super 8.8 yukon has a 4.56. If i had the 18 with the 3.24 first gear id want the 4.56. But on 15-17 id say 4.09 is good as i think its 3.66 first gear?

Where can I find the gear ratios for the MT-82 D4?

Here you go 3.24, 2.10, 1.42, 1, .81, and .62

Wonder what the '18MY skipshift(2,4,6) from 2nd gear on feels like with that range of ratios. ..better or worse than my '15 gtpp?

I think the gear spacing is nice on the 18. However i test drove an 18gtpp and i dont like the 3.73 with the mt82d4. Im more for 1/4mi so if i had an 18 id be getting a yukon 4.56. But thats just personal preference.

This is just my perspective, I had a T-45 with 4.30 gears in my old GT and loved first gear not hated it and that's with ~1500 less rpm.

4.09 is only 8% larger than 3.73.

I would love to get ahold of a 2018 manual with a set of 4.56 gears. The thought of it puts a smile on my face.

Yes but first gear is super low in a '15 MT82. Like a MT82 with a 3.31 has shorter gearing in 1st than a 1970 Boss 302 with the 4.30 drag pack diff and top loader trans.
