Joel's LS1 FC parts list/swap thread (remixed)

[AKINA FC]

A good friend of mine has The RPS setup in his Z06 and has been drving it for a while now (about 2 years), still loves it. I have the McCloed RXT setup and still love it after a year. Driving the two cars there is no difference between the two clutches (both have billet flywheels) and we both use the factory slave cylinders with no problems. I like the RXT and would recommend it, but either of them would be a fine choice in my mind.

Like I said ^^^^^. I did get a kick out of the fact that ther pressure plate is stamped "exedy".

I've used the ACT T1S-G01 twin plate in a couple cars, and love it, but some people have complained about the travel being 'low', but haven't experienced that in my car.  Great engagement (total street car) and handles 1000ft lbs or something.  Reasonably light, 40lbs shipping weight, actual clutch/flywheel/etc is like 36 or 38?  And it's $1100 or something, super affordable.

Thanks for the feedback guys.  Now when the time comes I'll actually know where to find it.

with the 36" speedway bar, what's the offset of your arms? (measured from the outside edge of the speedway bar.)

Also, did you do any calculations on the forces on those bearings?  mcmaster has "light duty" written all over them, and I imagine they see a good bit of force...

[frijolee]

-If you buy the arms from speedway they come blank (and long) so you can bend to fit (assuming you have the means to bend them)
-From memory it's about a 3" offset per side (including my pyramid spacers). 




-Bearings were these:  http://www.mcmaster.com/#standard-mounted-bearings/=m1wlem   

I did calcs on the twisting forces designing the bar itself but for the bearings I just ball parked it.  McMaster does refers to these as light duty, but with bearings that could mean rotation speed so who knows who's defining "light duty" in this context?  I will say, you got me curious so I did a little bit of math...  A P rating of 2000 psi with the area of 1 1/4" shaft size (1.25" x 1.313" width) means these are rated for about between 1970-3,280 lbf per side (the lower number is if you put a 40% knock down on the silhouette area of the bushing to be conservative).  I think I'd be doing math on the bolts first if I was really seeing those kinds of loads.  Yes you can taco an FD swaybar mount with a stiff bar but in that load case the path is pretty convoluted.

FWIW the bearing housing that comes with these guys is pretty close in sizing to the metal bushing straps that come on the RB bar I ran prior.  The kicker was that I knew several others who'd already run these succesfully.  ISCRacing.net used to sell a Speedway based FC bar that used these (don't see it on their site anymore but I might be worth a call) and several of Charlie's guys run them too.

PS for anyone else who missed it, there was quite a bit more info on the bar back in post #193

Thanks Joel.

I talked to speedway and they'll custom bend arms and re-heat treat them to whatever offset you want.  I was quoted @ $57 each

Those combined with a $111 bar, and 2x$11 bearings makes this relatively cheap.

You just have to make sure you have a straight shot between the mounting locations

[frijolee]

You probably want to factor in the end-links and chassis mods to let this bearing work, but I agree, it's a hell of a setup for not a great deal of money.  I'll see if I can get a more precise measurement on the offset I'm running next time I'm under the car.

Anyone know what the little brackets that interface to band clamps are called?

Been surfing McMaster for almost and hour and can't seem to find these (bottom piece, here shown by Canton with a pair of T-bolt clamps.


This is going to be used for my fuel filter (2" OD).  I could break down and buy Aeromotive 12305


But $70 for a tiny piece of billet kills me and really I'd want to two. 

[largeorangefont]

"T bolt mounting clamp" is what I've found them under in the past.

[ebdyguy]

Did you try to search E-bay for "Fuel filter bracket" ?  I found this one quickly but there are a bunch of billet ones in the $20 range.  Might not be exactly what you want though.

Good info gents, thanks.  Ash nailed the proper name but I didn't find the mounted style in anything smaller than 2.5" before Bill's link. 

The other piece of research that's taking too much of my time is planning power steering.  I've been trying to make this thing look decent to be able to take to shows and rep Ronin.  At the moment I have the GTO pump (which is ideal from a flow and pressure standpoint but is ugly as hell).  I also want to be able to play at track days and not worry about the pump failing and in general the stocker's don't hold up as well as aftermarket pumps (a big cooler would probably help that but still...)

I've narrowed it down to three options...

1) Stick with the GTO pump and replace the terrible looking reservoir...  http://www.pwrradiators.com/gto-power-steering-reservoir/.   That's all I'd be able to do on the bling front though...  Synister MotorSports used to make an awesome billet pulley for the 04-06 GTO but the company folded.  Shame, because it was rad and no one else makes a nice pulley for the GTO pump.

2) Buy the turn one pump: http://www.turnone-steering.com/online-store#!/~/product/category=4471097&id=19307275
-Plus the wazee f-body pulley (which is sex): http://store.wazees.com/Products/32-1997-2004-f-body-ls1-power-steering-pulley.aspx
-Plus an f-body PS bracket (there are a couple billet options for these too, but Alpers Motorsports has inconsistent pictures so I don't know what I'm getting and I'm not a big fan of CBM so I don't want to rock a big logo for them.

3) Run the KRC pump setup.  Their website is terrible so there's no way to tell the difference between iron and aluminum and to be sure which brackets are compatible with which pumps.  That said, it at least comes with a decent looking pulley and it might give me space to package a short catch can next to the reservoir.  This route might also be the easiest to tune.

I'm kind of leaning KRC at the moment, but I'm open to thoughts if folks have opinions. 

Whatever I do, I need a PS cooler since I don't want just run a loop anymore...   I've been looking at the Derale units.  http://www.jegs.com/p/Derale/Derale-Power-Steering-Coolers/1289908/10002/-1  Anyone have thoughts or recommendations on appropriate sizing?

I run the turn one pump and a 10 row -6 AN earls oil cooler for mine, good feel and good temps plus they use a nice roller bearing for the input shaft on the pump instead of a bushing. The wazee pulley would look good too. So that has my vote.
Out of curiousity, why not CBM for the bracket?

[frijolee]

Been talking to KRC.  Their iron pumps are rated to 5500 rpm (that's pump rpm and is basically the same as most OEM pumps), so for a track day car they said I basically have two option if I want the pump to live.  I can 1) run a big 8" pulley with the iron pump to let me play in the 6k+ engine rpm range at speed (my ATI -10% balancer is 6.78" diam) however, that might not have enough assist down low.

2) I could run one of their custom pro series aluminum pumps rated to 9000 rpms.  The downside to the pro series is that I'd be in for about $900 for pump w/ tank, 6.0 or 6.5" pulley, and bracket. The upside to the pro-series pumps is that KRC tells me I wouldn't need a cooler and it'd make the ability to package a catch can next to the throttle body quite a bit easier.  It's still a lot of money for a power steering pump though.

In terms of CBM, Ronin had a booth next to those guys one time.  Now they may have just been having an off day (it was crazy hot) but the guys running the booth weren't very friendly and the goods they had displayed were mostly non-functional bling: faux high rise valve covers etc.  In this case, the power steering bracket looks pretty nice, I just don't really feel like advertizing a brand name with random flames up up there.  If I bought it I'd probably machine off the logo.
