tortion bar setup for 73t clone update
 

i was very happy to get all the feedback that i did. it gave me a sense of what had to look for in the differet setups. i had to ask myself, what is going to be the main purpose for the car.i want to race it! i bought it with the intentions that i might wreck it and im cool with that as it is a very expensive toy. with that said i decided to purchase some used 23\31 hollow tortion bars.i will also be sending shocks to bilstien to be revalved. i know that it goes conterary to what many of you had said, but if i feel that if they are too agressive, i will change them. i think that 400.00 for hollow bars was a good buy.
by the way the front suspension is from a 87 carrera. the motor is a twin plug, crank fire motor 2.7 7r that i had machined at ollies with all the race prep work done.
i would like to start another thread on what you guys think on performance tires and also im in the market for solid engine and trany mounts
thnks again for all the help guys!
hers a couple of pics of my cars

Gorgeous. Are they 23/31 hollow bars with a somewhat lower 'effective rate,' or are they larger than 23/31, but with an effective rate of 23/31? That sounds confusing, even to me, but hollow bars are slightly larger in diameter to compensate for the loss of rigidity from the hollow center.

If they measure 23/31 -- and have an effective rate that's somewhat less -- then you've probably got a pretty great setup. If it's the other way around, it might be so stiff that a very light car has trouble keeping its footing over rough sections of track.

Speaking of which -- have you tracked it yet? If not, when do you plan on taking it out?

well, here they are.im not sure that i can answer that. i got them today from jeff at aase. as far as track days.......i still have alittle more to go.i bought the car for 6000.00 1.5 months ago. it needs all new bushings everywhere. it was someone elses project for 5 years and i think that, that is the best or most economical way to buy a older car. it has a new 2.4 motor with s pistons and e cams which i will probably sell later.trany has also been rebuilt. car has s options such as alloy calipers.i will sell those later as well. it all has to do with$$$. i want to sell the 914 so i can put the 2.7 motor together.i hope to have the car ready by the end of the summer, but you know how that goes. anyway heres pics of the new bars. love my digital camera!
ps
i saw your crash video. pretty scary$$$. my bro almost wiped out on that turn last year when he was racing pro thunder.

Does aase have any more used ones laying around?

Jeff is a good guy and knows his stuff. Any advice he gives you will be good.

ps

hey chris,

i havent been able to get the shock #s yet. i want to get them out soon because bilstien is kind of slow.im going over to check tre motors and look at there solid mounts . if i have time tommorrow i will go to pelican and pickupn bushings. sat sandblast 87 carrera suspension and paint. and sunday sunday i should have time to install front(minus struts) i love when a plan comes together.

Hi Guys,
Hope you don't mind me hoping on the end of this tread but my request is related. I understand the benefits of lightness for the hollow bars but are they as strong as the solid ones?

I live in Ireland and am building a rally car ('74 Carrera with full welded cage and 3.0 engine on webbers) and had a discussion with a friend over here who is already rallying with his '72 with cage and '76 3.0 carrera engine on webbers.

Currently he is upgrading his suspension(26mm rear tortion bars). I told him about the hollow ones on this site and he, and now me, questioned their strength and suitability to the Irish rallying roads. (For those of you who have visited the Emerald Isle you'll know what the roads are like and for those of you who haven't they are challenging in that they can be very uneven, small and between stone walls).


I read the threads but didn't find any discussions on strength or of their suitability for a rally application. Anyone know if they are used in rally applications?
cheers james

should be as strong

If I remember correctly from engineering school, the contribution to the strength of a bar being twisted from the material in the center is negligible. All of the forces are on the outside. Any way the best bars on the market IMHO (Sanders) are hollow. This is a time tested design. They will be fine. The T bars will be one of the last things to break in an off or over a "yump".

Glad to hear Collin will be back next year.
