Hey guys, I have done quite a bit of research and have yet to find some difinitave answers. If I missed a thread answering my questions please post it up.

I have a B series EG Coupe making 530 WHP and about 360 Ft Lbs of torque, I drag race the car quite a bit at a local 1/8th mile and will eventually take it to a 1/4 mile strip where I have a goal of 10.99ET. It likes to bust axles, I have a set of DSS axles sitting in the garage, but I feel if I upgrade axles I will start breaking tranny components.

So I am looking to "build" a tranny that I am comfortable/confident beating on with all that power.

Currently I have a B16 with a Blox LSD. I HATE how short it is and 3 times I have broken an axle I was not able to move the car at all, I think it is suppose to be able to move with 1 broken axle.

Anyway,
What I would like to do is an S80 (Integra LS) transmission with a 5th Gear Handcuff Brace. Obviously an LSD, Ive been compairing Quaife, MFactory, Syncrotech.. ect.. I would love a Kaaz but I dont think they make one for an S80...

I know LS is long but I would only be in 3rd in the 1/8th and to still drive the car on the street I wont be at 4500 rmp at 65 MPH.

So it would be:
LSD- of some kind
Carbon syncros
Delete collar

Disclaimer; I have zero experience with transmissions and I am learning on my own through research.

SO to my questions:

What else needs to be upgraded?
Have heard final drives will be the next weak link.. IDK

Any suggestions when compairing LSD's ?

Cuff/5th gear replacement brace: Are they effective? The concept seems like it should help alot. Any input?

Gear sets: No one ever actually breaks "GEARS" correct so as long as I get the gear speed/ratio I want out of stock gears/tire size they are fine correct?

Face plating through Liberty Transmission?
Anyone ever done it? Again the concept seems legit? If anyone has done it, how much does it cost?

I think that is all.

I will be having the trans disassembled/reassembled by a friend, a 30 year Honda Technician so time apart/labor will not be a factor.

Thanks in advance,

What tires and clutch are you running? I agree that something somewhere has to give.

If you are running drag slicks or a clutch that is far more than you need then the next component down the line will see more stress.

Is the geometry of the axles good?

You are definitely making a good amount of torque but the stock axles should still hold up relatively well. Are you breaking a lot of axles or just one say every dozen times down the track?

I'd go with a GSR tranny, MFactory/Quaife LSD and the SpeedFactory shift change holder assembly with the braced shift fork.

M/T 24.5" x 8.5" slicks
Comp Stage 4 Clutch
Axle geometry is good: The car is close to stock height

3 broken axles in 9 runs. Swapping them gets old..

I had heard of/seen broken or bent shift forks.. and the SCHA dosent look to be a bad investment..

Thanks for the info..

 

I run a stock gsr transmission with LS 5th gear with over 600whp E85... how does it work....

1 1/2 Torco MTF and 1/2 RTF
and the Speed Factory Shift Holder Assembly

 

Do you drag race your car at all? With slicks? And u don't break axles? Or tranny components?

So you are saying u mix MTF and RTF? And u only run 2 quarts?

Thanks for the info..

 

are you preloading when you launch? or just dumping the clutch?

 

^^^^ what he said if ur not preloading that's the problem I have over 600hp and have done 20 passes on stock axles

 

you dont need to do anything to your tranny or axles.. learn to drive better that should work.

 

Well everything sounds normal except the 3 broken axles. Like others have said, need to do some pre-loading that way you aren't just dumping the clutch.

I run Torco MTF fluid.

The stock axles and handle a lot and shouldn't be breaking this easily.

 

First of all.. Thanks for all of your input, but I didnt post this thread asking for drag racing tips..
BUT..
Yes I preload.. I preload from the first staging light to the second, or else I think would have broken 20 axles in 20 passes.. I am on 24.5" x 8.5" slicks..

What size tires are you guys running? clutch?

This is like the 3rd thread of mine you jumped in and were just an *******..

Will def run some better trans fluid once I have this thing back together.
But what size tires are YOU running? Clutch?

 

I'm just running street tires but I'm also not making as much torque as your car. Something is definitely wrong somewhere because stock axles will withstand a beating. At what point do the axles break? Oh, and I'm using a Competition Clutch Stage 5 sprung pressure plate with a 6-puck disc and a CC light flywheel.

 

Kind off topic but how long have you had that clutch with that power?

 

Ur doing something wrong I'm on same slick but 9.0 wide with more power Twin disk clutch

 

Well street tires would explain alot.. your weak link would be your tires.. they will spin alot sooner than my slicks under the same load..


I made 470hp/325tq last year and went to the drag strip 6 times/20+ passes and never broke an axle. I made 530/360 this year and I have went twice/ 9 runs and broke 3 axles... all on the same clutch

On stock axles and tranny?

I dont know what then,.. Like I said to dc4lsteg.. Last year I never broke one axle.. I was preloading and launching the same way I am this year.. only difference would be my power/ tq level.. I am on the same exact slicks as last year, same clutch.. IDK..

 

Just curious.Do you have a traction bar setup on your car and if you do did you set them up to pull back or push forward to apply tension.Like I said I am just curious.

 

is it wheel hopping slightly? did you mess around with the rear spring preload? try changing up your tire pressure and such so that it just flat out spins the tires, then back it down from there till it hooks up

 

Yes I have a Full-Race Traction bar.. and that is a good question.. I didnt really want it to do either when I installed it.. I just made them tight with the car at race height.. SO I guess it would be "pulling" slightly.

No, I have zero wheel hop.. Yes I have Strange Engineering suspension and I have the rear struts set to full stiffness on the compression adjustment and half on the extention now. I forget exactly what my rear spring rates are.

One of my runs.. Zero wheel hop.. Crappy et, 3rd gear misshift.. but it shows my burnout and no wheel hop..

Here is a better run.. 7.18 ET at 103 MPH
http://www.youtube.com/watch?v=ypCJ9EBf2bc

Tire pressure has been played with. I run my slicks at 8.5 PSI cold.

Again guys I really appreciate all the info and help, and trust me I dont mind discussing my steup and have no problems taking criticism about it b.c. I am always learning about setup advantages and disadvantages..

BUT.. I would like to address the OP, and I would like to know what should get replaced/upgraded inside my tranny while I have it apart.

So as a whole you guys are saying NOTHING is known to be the next weak link?

The stock final drive ring gear will hold up if I put bigger axles and a diff in it?

So I guess all built trannies are just overkill for a 530 hp car?

Thanks again guys,

A few buddies of mine run b16 gears with a 4.0 final drive, Mfactory LSD (great bang for the buck), and depending if it's a solely a track car they went with a 5 gear cuff.

 

Yes stock axles liberty shift plated gears not a dog box. How's the midshaft is all tree bolts there I broke two axles on the first launch when I had only one bolt holding the midshaft cause the block I bought had two stripped threads I fixed that and haven't had a problem

 

Also what axles are u getting them from advance or Autozone cause Autozone axles suk

 

This is where I am at. I think I can use this exact setup to get what I want. I want to stay in 3rd gear in the 1/8th and only go to 4th for the 1/4 mile track. Currently I am trapping 103 MPH in the 1/8th, so, if I use my B16 tranny with a 4.05 final drive I will be able to make 108 MPH on 24.5" slicks at 8800 RPM. Also it isnt SOLEY a track car but I rarley find a chance to drive it on the street although it is street legal, but I think 5th gear cuff is a good idea, because with the setup I just described I will be able to do 151 MPH on my street tires in 4th gear.

How much was the Liberty Shift Plating? Do you like it? Can you feel a difference?

Ahh, That is a good question I remember having to remove the whole intermediate shaft to pound out the broken piece of axle from the other side of the tranny, In the dark, on the ground, at the track. So there is a chance I left one of the three shoulder bolts loose and it worked its self out, I will have to check. Thanks.

I acutally did a little asking about this when I was shopping around. Autozone uses refirb axles and they are ****, Advance sells refirb and "NEW" axles. The "new" ones are alot nicer. That is what I use. Although I have busted both Autozone and Advance axles to pieces. But I just installed DSS stage 3 axles so I hope I dont have an axle problem any longer.

However a little update I went to the track last Friday and I am thinking I bent a shift fork b.c. I went down the track 6 times and the car WOULD NOT shift into second or third gear at speed, and the shifter is hard to move from gear to gear. I guess its time to pull that bitch out and tear it apart.

Anyone know of aftermarket shift forks? I thought I remember looking at a set online but I cant find them again. I have heard of this being a common problem so I guess I wouldnt be opposed to buying a reinforced set or making a better set at the shop.
