TCP Rack & Pinion

[The Dan]

First off let me say TCP is the worst company I have ever dealt with. Customer Service is actually Customer Dis-service.

But...This rack & pinion unit is insane. This car drives so different. The unit is a work of art in itself. Lots of blue and red anodizing and raw aluminum. I got it with the KRC pump and that makes for an extremely clean install and look as well. You can feel the road under you like you can't believe. There is zero lag on the inputs. You move the wheel a centimeter, the car goes that direction. It is really amazing. Then again the $$$ you spend on this unit it better be!!! Anyways, just thought I'd give you all some feedback.

What will happen in the future when a seal or pump goes out and you need a replacement part?

 

[The Dan]

I thought about the same thing. They have a forum on the TCP web site, and of the few units that had leaky seals, TCP sent replacements. Seems not everyone has had a bad experince with them. As for the pump, it is made by KRC, so I would deal with them direct. I will say that the quality is superior, so I don't imagine having probs anytime soon.....knock on wood!

If something happens in the future, you'll be able to get parts from Chris Alstons Chassisworks, as they have bought out TCP.

You've got me excited Dan, I just had the manuel R&P installed and didn't get a chance to drive it before I took it to get my big brakes done. Can't wait to get it out and drive it!

Have fun

Chris,

Your going to love it! I heard the manual is a little harder to turn the wheel, but it is just as responsive. I went from 3/4" play in the wheel to absolutly zero "slop". Of all the mods I've done to the car, this single one made the most noticeable difference.

Let me know what you think.

I think the KRC pumps are rebuildable. Check KRC's website for info.


FYI: TCP charges you $100 just to put the kit together. You can buy the pump, tank, brackets, and better hoses for less than $500.00. The only thing I'm not sure on is the flow valve rating.

i love mine too, i just need to get the krc.....stock pump wines quite a bit, but its tolerable for now. i finally got it alighned this last weekend for the first time since i've had it on in 2 months and damn, its a straight shot down the road. really responsive. responsive was the furthest discription from my old set-up ever. its a really nice set up! i think it was woth the money, but that opinion is pretty relitive.............

TCP for the quality anyway​

almost everything that is in the rack is made up of common over the counter, most. the whole servo is a product of woodward racing, the universials too. so that takes care of the pover end, pinion and snubber/bushings. the cylinder tnd has seals in it, i'm sure there are replaceents, just not sure on the source. all this is of cores if tcp can't help you out.

I enjoy mine too but I think it's almost too sensitive. There is zero play in the wheel. I mean you move it a fraction of an inch and it shows movement in the tires. I have the 105 gpm flow valve already on my krc, but it's still way too easy for me. I am considering a bigger pulley to slow down the pump pretty quick...

there is an other way around this problem. have you got a woodward catalog? if not go to the site. here is a break-down of our servo...

notice the tb170 rod.....

here is a link to where it talks about the change and why...

i highly suggest contacting them about this, woodward got screwed by tcp, so i always sence some bitterness there, but they are very helpful.

 

[streetgrande69]

here is some more servo tech from the site, look around, there is so much info there, its scary!

Changing to a stiffer torsion bar reduces the degree of twist resulting from a given torque at the steering wheel and, consequently, reduces the valve opening. This, in turn, reduces the rate of flow and, therefore, the rate at which pressure can build up to overcome resistance. The result is weaker response to the driver’s demand.

so move up to a larger torsion bar and it should help witht he responce problem you don't like. i'm also thinking of doing the same. i need to talk to them and find out what torsion bar it stock on the tcp units.

Interesting info. Thank you I'll look into this further..

I know just what you mean. Our '67 shop car was very touchy especially on the highway. If you have very low miles on your rack, it will break in and become more comfortable to drive. Otherwise you can back off the set screw adjustment just a touch to add a tiny bit of play to the steering. An 1/8" of play at the steering wheel is enough.

The 1.05 gpm fitting should give you plenty of resistance in the wheel. You might want to try adding a couple of degrees more caster to your alignment. This will give you a heavier feel at the steering wheel. Another simple adjustment would be to drop a couple of pounds of tire pressure in the front.
