Lets talk clutches and everything drivetrain related

ACPT C/F Driveshaft Group buy is a go!!!

Postby Sifu » Wed Feb 13, 2008 6:23 pm

Group buy is confirmed!!! We need 10+ buyers!

Now before anyone jumps up and screams YEAH let me get some things out of the way.

- 1 piece design (vs. 3 piece)
- 17lbs. vs 40+lbs.
- 1,000tq rating

10+ buyers and the price is $900USD.
S/H to the greater 48 States is $35
S/H to Canada, Hawaii or Alaska will be $60
International orders must be converted to $900USD and s/h will be around $200~$250 (Jim mentioned that most European shipping is around $200+ and anything further than that you'll start seeing that climb).

Money must be paid to ACPT upfront and when the entire batch has been made then they will ship the units out. I assume this will take some time because the quote I got was for about 3 weeks for one. Add 10+ driveshafts and you'll get an idea of time required

We can't go any lower and this is subject to change or revised. Mr. Martin may chime in here to answer any questions too. Again this is open for debate but please if you are interested again let me know.

I know that $900 might be high for some people but understand that we are saving a chunk of it w/ the group buy. I don't think we can wait too long so once the 10 buyers are in then they will be made and mailed out. If we have 30+ buyers the price will still be the same but hey at least you don't have to pay $1,200.

I will also email Robert to let him know about the GB.

So... Who's in since it's been confirmed?

Here are the interested buyers.

1) Sifu
2) Ripley
3) Etantshi
4) Jonstew
5) RedCelicaTRD
6) Suprakid95
7) Wolf_Tm
8.) Camry90
9) Turbo4wd
10) Celi-GT4
11) jramirez
12) Speedtechniknyc

??? Meurz
??? TJDouble07

Thanks goes out to Pat and Jon for bringing this forward to our niche community and to Jim Martin at ACPT for helping us get this group buy going...

***UPDATE***
The deadline will be the 2nd week of March. This way we can get our CF driveshafts around April.

ACPT will take Visa and Mastercard (sorry, no AMEX or Discover). You will either email James at jmartin@acpt.com and just title the message "CF Driveshaft Group By for Toyota Alltrac." If you want to ask questions then this is the time to do it. If you are satisfied you can add your CC type, full name, number, expiration date. International orders I suggest you email him because it will be a $$$ phone call and you may not always get through to him.

James number is (714)895-5544 #220. This is probably how I am going to pay via phone.

The money will be put on hold from your account and will NOT be swept until they ship the units out. They will also ship them ALL out once they've been made. I suggest international orders to contact James and get an accurate shipment cost.

Just so we can get a head count please provide your user nick with the order. I will then contact James before the deadline to see who has locked in their purchase (I know some people don't like to use their real name online so this way is easier).

I've given my CC over the phone and over the net before. ACPT is a reputable company that has worked on Dan Gurney's IMSA RWD Celica. I'm sure that's why Pat and Jon either knew or heard of the company. I wouldn't be scared of passing your CC info to them.

Lastly the question of CF in cold climates. James mentioned that this is a common question for most Canadians and assures that if it hits -100degrees then it would pose a problem. As for the melting point of these driveshafts they do get hot since they're close to the exhuast system but since air is constantly being passed over them this should NOT be an issue.

Later down the road I would jump on this but as of right now I would have to sell the car to pay for it... Not sure if that would make sence in the long run... :doh:

Hummmmm. Very interesting. I'd be in if my tax returns are big enough. Is that a discounted group buy price, or is that the regular price?

And aparently if I was smart enough to read I would have noticed it said you haven't talked to them yet :twisted:

That's the quote I got for a single piece (no discount). I haven't asked them for a GB but can only imagine that we'd need like 10+ buyers. Just seeing if there are anyone else interested.

^^ are there any negative effects to a 1 peice prop shaft?

I'm very interested, after learning 1st hand how heavy the stock one is, id like this one very much.

I'm not sure. I will ask them about the slipper.

Besides the obvious fact that a slipper is a warm and usually obnoxious fuzzy shoe what's a slipper for a drive shaft? :P

I've read some of their driveshafts from the Subaru boards and they don't have much of an issue with them (slight vibration at 60mph but then it disappears). The only real person that can answer this question is Pat.

Pat and someone else has one.. there were two floating around.. I think Jon Stew has the other..

I want one, but if I needed it now, I would've gotten it when Pat asked me a few months back - its something I've got to hold off on for now..

But I'll definitely get one later.. hopefully within the next 12 months.. :P

As for "shattering". CF drive shafts don't shatter, they break up into fibers.. They're actually considered very safe - with that said, it wouldn't hurt to incorporate a scatter shield / drive shaft loop.

I seem to recall Pat running a loop on his setup..

Doesn't NHRA drag rules dictate that you need a loop if your car is 12sec under? Anyways yeah whatabout that slipper? :wink:

The one peice shaft would be a bit trickier to remove from the tranny wouldnt it?

How does it come out if it cant bend in the middle?

the current driveshaft can be inserted and removed from the rear output if you unbolt the two front/rear engine mounts and tilt the engine/tranny enough. its a close squeeze, but you could also unbolt the two side mounts and use a cherry picker to suspend the engine while shifting it forward a bit if necessary. i don't see taking it in and out as a problem.

Negative effects would be
- If it breaks you gotta' get a whole new 1 piece
- Installing will require a little more work but nothing out of the ordinary
- Maybe less forgiving than a multiple part driveshaft

With that being said I've always taken my driveshaft off from the transaxle and never had issues (yep, tilting the engine just pops it out for me).

A mulitple part DS would help transfer tq. to specific areas and would also help in replacement of any bent/broken DS along the chain. It may also help with shock load if the auto should ever get airborne or if the engine isn't reinforced well to the chassis (think bending and snapping vs. rotational shattering).

Our driveshafts are VERY beefy for what it's suppose to do but damn they are also heavy (pros and cons in weight). I'm no drivetrain specialist but that's what I believe in theory.

ACPT mentioned that its rated at 1000tq and the next step up is like 2500tq.

ah pictures....

These are pictures of Pat's driveshaft, I have not actually bought one yet as I was waiting on the fastest, most powerful All-Trac (I know of) to beta test it. These are pictures of the first driveshaft Pat received, it was 1/2 an inch too short. Pat now has the correct lenght driveshaft in the car and has spun it to 10K RPM on 25lbs of boost in 1st, 2nd and 3rd gear and last weekend made some guy in a Lambo feel pretty bad about what he "thought" a quick car was from a dig. I think Pat told me he was going in soon for some dyno time to see how it handles around 40 lbs of boost on race fuel. According to what he told me the "seat of pants" dyno was telling him it revved faster and naturally felt a little quicker.

I do plan on getting one so count me in, I believe Jim Martin told me if 10 people bought them they would be 1,000.00 plus shipping (35.00) but that could have changed since the U.S. dollar is not worth squat right now.

I thought I'd come in here to give you guys some piece of mind...

First of all Jim Martin was very helpful & met the requirements I needed for this to work.

the low down:
stock weights 45 lbs w/o bolts
composit weights 16 lbs w/o bolts
about 3" in dia & 72+ inches long
closest clearance to body (mount reinforcement for center carrier) 3/16"....this really concerned me, but Jim assured me it was OK since it doesnt deflect that much...it was more elastic in a twist & wont wobble

you dont have to touch the engine to install it....just put the yoke in till it bottoms (about 21/2"-3" in) then bring it rearward about 1/2" (this will give the yoke some room for movement) even though my engine doesnt really move much...just room for safety (you dont want it to bottom out on hard launches).
the lower rear cross member will need to be removed (just below the DIF) & you'll need a catch pan for the tranny fluid (at the output )

I'm still about 3 weeks from a dyno test, but its been street (street race) tested to 9500 +rpm in 3rd. No noticable vibration!
car seems to rev much easier, but really cant tell since I did the Tilton cc at the same time...dyno plot will reveal the answer.

A realy quality piece, the u-joints are rated for more tq than I'll throw at it. I put about 300 lb/tq to the rear wheels, it will take that all day long.

Pat
