Is it balanced?

I see no reason why it would need to be "balanced".

1. It's a precision machined part which is already inherently balanced pretty good.
2. It's a small diameter.
3. It won't ever spin very fast.

A very resonable $200 from Liberty's Gears here in Michigan.

Cool. Since we're drilling extra holes and adding material here and there I wasn't sure if balancing was important.

It will cost much more than that. The ring gear is only available with the differential. You have to buy the assembly.

You have the parts list right...
Countershaft
Ring gear/differential
Oil drive gear
Countershaft bearings

Probably a good idea to get new seals too.

This isn't a mod for the faint of heart, wish it was a little more mass produced without the need to re-drill.

It's hard to say exactly, but I think the FD is good for 3 tenths and 1.5-2mph. My best run previously at the same track (in conditions 1400 feet MORE below sea level) was 13.46 @106.66. That run corrected to something like 13.8 @103.8 whereas this run corrected to 13.44 @106.2.

Trying to get it corrected through Hondata but I only know of 2 people that have it, so I doubt they will make it.

Top end seems to have more to be improved.. Looking at your mph on the middle and 3rd slip.. You trapped 2mph more at the 8th but car still somehow only managed a 107mph pull. Never the less.. Amazing

This is impressive but I think we haven't seen it's full potential based on the corrections you mentioned. Under similar conditions, this might be a 110mph car. Does 110mph mean an extra shift or can you stretch it out a little more?


I imagine on the street it has to be a lot more fun and with less chance of being caught "in between" gears and out of the powerband.

Reason for that is my 3-4 shift. 3rd gear maxes at 85-86mph so I must've shifted earlier on the slips showing 82.x in the 1/8th. Looking at my Datalogs, I don't see max RPM of 7400 in any gear, so mayyyybe it has a little more in it? I can't be sure because I don't imagine me continuing to make power above 7200. But yea...23-24mph in the back end is exceptional for a bolt on 3.0L V6. I'm sure the gearing helped it a bit because I don't believe I gained any power from the cutout over my 3" exhaust. I will have to dyno again at some point.

Well, my drag setup is ~8lbs lighter per corner, so that could have some trap speed implications. I think it's nearly maxed out in it's current state. Surprisingly enough, I wasn't powershifting so mayyyyybe I could've seen 108mph traps? But that would be the max IMO. Also, this was in below sea level air (-1100ft), so the 'corrected' trap was just over 106. Either way I'm very happy with the results.

The car is so much more fun to drive around town. The low end is much improved due to the higher torque multiplication and it's much more difficult to catch me outside the powerband Not that this means anything because it's so absurd but....I ran into a Panamera Turbo a few nights ago...lol. I heard him punch it a few cars ahead of me so I figured hey, why not. I get beside him, open the cutout and downshift (~60mph in 3rd) and we both punch it. To my surprise he only pulls 1.5 mayyyybe 2 cars to about 100mph. Considering they are mid 11 cars @120mph, I took absolutely nothing away from this run lol, just fun. More than likely he had a packed out car and Santa in the trunk Sounded nice though.

Oh btw, 4th gear stretches to 115+ so 110 wouldn't be a problem. Although I can't imagine trapping that high in somewhat normal conditions unless I added more mods and/or took significant weight out of the car.

Do it up. My 21 lb Braille, F14s with Conti DW, back seat removed and stripped trunk liners is good for 120lbs. That's in addition to the 36 lbs of the spare/jack/tools. Accord should be similar. That'll show another mph easily, and the seat and trunk liners can be put back in less than half an hour. Add some mild cams and I'm confident you'll see 110 mph in the same conditions.

Only one way to find out What are your mods?

Tyler: I'd love to take some weight out but it's my daily and I enjoy all the comforts it comes with lol. Mayyyyyybe one day I will take the back seats out, but that's probably only ~50lbs. Plus I'm going to need a 4dr soon

Spare tire and jack will erase ~35lbs. Get a air compressor, tire plug and jumper cable road emergency kit, will weigh ~5-8lbs.

~17-22lbs battery another ~15-20lbs off vs OEM battery.

Lightweight flywheel and pulley will shave off another ~20lbs.

Front and rear bumpers another ~20-30lbs.

Creature comforts left intact

Think he already has a LW flywheel. I believe the bumpers weigh 35lbs combined. I was going to ditch them myself, but then I ended up getting rear ended at a red light. Car stopped behind me decided to go before I did, basically. That made me change my mind. No damage, but there would have been if I didn't have the bumper.

Dam sonnick your car is getting fast.
Today was my first day at the track since my 6speed swap.
My clutch aint broken it yet but I was only running 8.4's mid to high 86mph in the 1/8 while doing consistant high 1.8 60ft's on the motor.
something was not adding up for me.
Mine ran 8.3 @87+ on the motor when it had the Auto trans.

Autos are consistent and much easier to launch, manuals are harder to do so, especially without practice.

A base TL 6MT is only about 180 lbs heavier than an '06 6MT AV6 coupe (3482 vs 3299 lbs). I think Sonnick is in the low 270's, so in theory, let's say 290 whp, as well as the 3.94 final drive.

Unless you are revving higher, it's not worth it. 3.55 from the 8 and 9G 6-6 would be perfect for you. I am revving to 7400 and it's great, but it's too short for the stock redline, especially for your 3.7. You will shift to 5th, ask Simione.

I'm only running 1/8 mile.
I'm right on the limiter in 3rd at the lights on the motor.
So I should only have to see 4th i'm thinking. Spraying should be fun.
I'm looking into tuning too soon.
Anyway I got his so called last set on the way.

Any 7th gen Accord owners interested in a package with a 3.55 gear and an LSD? I'm a 9th gen owner with the 3.55 and I'm on the cusp of convincing MFactory to build an LSD on our application.

This benefits 7th gen owners because you can just use the LSD and bolt it straight to a 3.55 gear and install it into your trans!

Whatever happened to MFactory making 3.80's or 3.94's for $700-800? I'd be in, pending finding a competant, relatively local installer. I personally wouldn't do the 3.55's as I don't think there would be enough gain to justify the overall price, once install is factored in. I'm guessing $800-1000 to install, and might as well add another $1,050 for an Xcelerate clutch/lw flywheel while they're in there. Ouch.

If MFactory did anything, it should be a 3.55 ring gear with the 12- bolt pattern. That would be the least amount of investment and the highest sales numbers.

Anyone that has swapped from a TL Type S 3.284 final drive still have all of their parts? I'm looking to pick up a 3.285 FD and was hoping that someone that had made the jump to the 3.55 or the 3.842 still had their stock stuff. PM me or message back
