Porsche 944 turbo road to racecar.

[333pg333]

This is going to motor! Has anyone ever adapted the twin cam head off the s2 that you've seen?

You wouldn't bother adapting the 16v head to this block. Just turbo an S2 or 968. Different blocks (not by much). There's a few of them out there. My mechanic has a turbo S2 motor in his 944t. Goes pretty well. Hit's 265kmh down Eastern Creek's main straight. Well, on his speedo anyway. Take off about 5-10kmh but it gets along nicely.

The half height "Saintz Bar" looks good.

You've got me there Dave? I know I should understand...perhaps hangover is blocking memories...

IF it is a CAMS Spec cage, the top join should be 100mm max from the longitudinal bars/ top of front roll bar,not 1/2 way up the front windscreen .

Have a look at section 17 .drawing J-59 of Schedule J in the CAMS Manual. That is diagramatic but the text explains all.

Also, DrawingJ-17 in Section12

Right....after battling with the CAMS online manual for 20mins trying to find that section!!!!!!!!................I see what you mean. The question I have based on those parameters that they set is getting in, and more importantly, getting out of the car if you put the support bar in as they dictate? Or you have to have it on such a forward angle as to essentially mimic the windscreen pillar/leg. So I'm a bit confused about that. To me it seems that the idea of that extra support is to triangulate yet not at the risk of reducing driver exit path? You can see a better shot of my cage in the first pic of this thread in post #14. From what they want, I can't see how it wouldn't severely restrict my egress in an emergency situation. However I take your point.

[Dave75]

Shoud be on or within 100mm of the front hoop base mounting adj to th "A" pillar & 100mm max below the longitudinal/lateral bar join at the top.It can be bent to max 20* in front view,but must be straight in side view.
Looking post 14 pic it isn't technically a Saintz Bar anyway,more a Reinforcement bar for the door bars & if you intend using the car for TA...anything goes.
Most Saintz Bar I have seen don't weld into the Door Bars ... usually a separate one piece bar from Base of "A" pillar to the top join of the longitudinal/lateral bar ,inside the door bars as J-59 shows,hence the bend in front view.[which will give a 50mm reduction in space adj to your Right Leg.]
Obviously ,if the cage has been passed by CAMS & has the all important plate/sticker attached ,I will make no further comment.

PS Very nice Car!!!

PPS Saintz Bars only compulsory for National & above this year, but also compulsory in all other Circuit Races in 2013 [State/Sprint ]

Dave, I appreciate your input and observations. http://www.camsmanual.com.au/pdf/10_...e_J_2012-1.pdf
I think that the allowance for the distance in dimension A in picture J-17 would cover almost all tin tops. Unless you have a vertical windscreen, that measurement is always going to be at least 200mm or 8". So they're all going to require that support or 'Saintz bars' are they not? I'm an absolute minnow and amateur in this field but something seems a bit odd in that requisition. Also from what I've heard, the parameters on CAMS cages change on a semi regular basis. I also have some other triangulation up on the main lateral bar. I'm sort of thinking diagram J-45 is a compromise of both concerns? So are you saying in dia J-59 that the Saintz bar actually goes on the inside of the door bars? I still see this as an obstruction to egress...but I haven't had time to do too many dry runs yet.

[rowdytoot]

cage requirements have changed for the 1st time in ? (Dave will correct me- I'd guess 10 years or more?) certainly the 1st time I've seen them change since I've been the sport- ie since 2002-3, and I'm a regulations reading freak.

it's not odd at all, and the impediment to egress is almost 100% in your head..

This is my new favourite car on PF. Just sayin.

Feel free to kick in to the $ appeal!!

[Dave75]

The Saintz Bar "introduction" has been dicussed for about 3 years [same as Cameras]

But 2012 is the first major change in the 8 years I have been involved.

The 2012 Cage Regs have only realy changed minor wording in most cases, but the Saintz Bar is the main change... National & above for 2012 & all other Circuit /Speed events in 2013. I think the main "change" is that CAMS have at long last written the Cage Regs in a more easily read way.. all sections relating to a particular tube is accompanied by the relevant diagram in the same format as the FIA Regs using the "J-# style instead of the old "253-# previously,so hopefully Rowdy won't have so many opportunities to have a go at me.

Definitely in your head if you think the Saintz Bar will interfere with egress in an emergency ...works alright for V8SC & other classes...even Porkies with engines in the wrong end.

A bit Off Topic, but we have a Supersprint Driver in SA that is in the same situation as Bevan... paraplegic... with a full cage & 100% Hand Controls & he had to prove to the Stewards/CAMS that he could exit the car in the required 7 seconds before they would issue a licence. The rescue teams are warned when he is driving ,to pay a bit of extra attention in case he needs help. If he can...you can!!

[333pg333]

I see this is an international change. http://www.customcages.co.uk/news-ro...nd-update-kits
Interestingly they only seem to be saying that if the front leg has more than one bend you have to implement the S/B but otherwise, no? So am I right in saying that Cams wants this bar no matter what your front leg is? (Provided the measurement between top and bottom of windscreen is more than 200mm in profile)
Also, is it only if you want to race Nationally or above that this is mandatory? Thanks for the info too.

[rowdytoot]

you're not allowed to have more than 1 bend in the front leg, full stop.

Dave- tee hee:D and yeah, if the cripps can manage it no probs, us cunts with working legs have no excuse :D

[333pg333]

What about the front lateral bar (not sure what the name for it is?), under or over the steering column? Is this an absolute?

[rowdytoot]

lets get one thing sorted before we go any further- is the cage approved, and is the car logbooked with the cage already? If so, worry not about anything except intellectual discusions :D

FWIW my reading of the requirement is the the front bar at the base of the windscreen must be above the steering column, no ifs no buts. Give CAMS technical a call to be sure..

[333pg333]

The cage was built a year ago. The car isn't quite finished yet and that's when we were going to call in the engineer to do his thing? So, no. Not Log booked yet.

[rowdytoot]

ahh I see. what you should have done late last year ( if you knew this option was available- but it wasn't widely publicised) is to apply to CAMS for an exemption from the 2012 cage regs since the cage was built in 2011 but the car wasn't going to be finished to a logbookable state in 2011. They would then allow you to finish & logbook the car during 2012.

It may well be worth talking to them about the exemption though and saying you weren't aware of the new regs, and you're car isn't finished etc...

I took the other option and had my cage built to comply with the 2012 regs so I didn' need to worry- but my cage was built after the 2012 regs came out, so I could do that- others couldn't!
