TH400 question(s) and help
I've been looking to buy a TH400 for my "Sled" project (68 convertible corvette pro-street) in which I will be running a LS 5.3 turbo. This is not intended to be a drag car at all, just a hotrod, something cool to putts around with somewhere around 650-700 crank hp, nothing "stupid".
I used to have a JW th400 with t-brake in a different car so naturally I started looking at them again.
I am a little confused with their hp ratings: the two I saw both have reverse manual VB (no t-brake), one is drag free, rated at 1000hp, the other is not and rated at 800hp. I emailed them and they said internally they both use the same components, one being drag free is the only difference.
I'm not sure I understand why "drag free" nets you 200 additional ponies of holding power (and I can't find the answer online either…)
Does anyone know?
Next I looked at FTI TH400 level 4, which is rated at 900 but this one has a billet forward hub and a T-brake, which the JW do not, thus I raised my eyebrow and wondered what the truth is between all those hp ratings. FTI equivalent to the JW would be their level 3 it seems, which is rated at 750
Price wise, the FTi level 4 cost 200$ more (and chage) than their level 3 or the JW 800/1000hp one. It's not a huge difference but I don't like spending more than I need or is justified. I honestly don't think I need the level 4 FTI trans, though I could be wrong…
Thoughts?
