Can a 914 be competitive in Historics?

no fibre glass.

Also the 914 will be in the 1600-2000cc sub category. So you are giving away 200cc to start with.

Thanks for the PDF... read it thoroughly and understand that basically, the Sc class is period Showroom Stock with a little wiggle room so long as everything is steel. That part seems kinda regressive since plastic was used on lots of SS cars in period. I'd ask for clarification and bring a file of evidence to validate inclusion. If there are examples of teeners racing in Australia in the 1970s and you get the OK, it's all good. Remove all the glass, strip the doors, cutting the majority of the internal structure, drill the rest. Chop the A pillar off, add the low windscreen, 6-point cage and the standard 914/6 stiffening kit. Upgrade suspension components and brakes as in period, and since the later teeners are 901 sideshifters, no slop with upgraded bushings and a variety of gearing choices. All good on the 14X6 wheel size and 60 series rubber, too. As to the displacement issue, well... ^^^EDIT: Good point, Dave! Two liter it is!

Russ,

What kind of hp are people getting out of 1.7 or 1.8 914 motors these days? Internals are free but capacity is limited to a 1mm overbore, single plug and solex carbs.

That's the best part... with internals and induction basically open, given enough $$ you could easily see 200+hp with the ignition allowances provided in the rules. But it's a fat flat torque curve that wins, and getting a dependably understressed 160 hp or so from 2000cc with somewhat more torque is the Type IV's strong point. See Jake Raby for how it's done.

The 1974 914 came in a 2.0 version, why give up 200cc?

Different class, it will be in SCa. I think John was thinking more of the alternative to 901 in class SBc.

This is confusing, only '70-71 production years accepted for both 914/4 and 914/6? Were any raced in Oz at the time?

Russ,

I doubt any 914's were raced in period in Oz. A handful of early 911's were raced in period, but in touring car (ie. not sports car) races.

As a result, 911's can be built to a period-ish spec for historic touring car racing (Group N) in Australia (eg. ST flares, 2.3 litre twin plug motors, 7" wheels or in narrow body 2.0 litre form)

However, the class we are discussing at present (Group S) is a production sports car class, where the reg's are more based on how the cars were delivered in stock form.

As to why the 914 spec sheets only list 70/71 - who knows? One guess is that was the age of the first 914 that applied for a logbook and caused the spec sheet to be created.



Ps. A 928 powered 914 was built and run here in the 80's?? for Porsche Cup - clever interpretation of the reg's requiring a Porsche drivetain and a Porsche body/chassis.

[Alex Webster]

914's were never made in RHD from the factory and therefore never raced here (main reason).

The one 914 body that would have been considered right to bring out would have been one of the 916's which were effectively 2.7 twin plug RS motors bolted into a 914 with big flares - and they only made 16 of those!!

G'day Guys

Russ, thanks for some insight on modifying the 914 for weight. I was aware I could build a pretty effective TypeIV engine. As Alex has indicated, the fact that the teener was never a factory RHD meant it was never raced over here "in period" racing trim, so I'd effectively be restricted to setting it up close to stock configuration. A good 901 is pretty expensive over here, and and on my modest income I'd be reluctant to race one The 914 on the other hand is considered a bit of a white elephant over here, and the ones that have arrived are pretty cheap to buy in comparison to their rear engined sibling (giving much more $$ to play with go-fast goodies). I have enough bits and pieces to build a pretty good 914/6 replica (given a nice shell), but alas replicas are also not permitted

There are other classes, but I do like the idea of running with the guys on this board And I like to be a little bit different...

John,

I'd aim for one that can run in Sb and go for it. Group S grid numbers are very healthy and there will always be someone to race whether you're front, back or somewhere in the middle.

I can give you the contact details of some group s scrutineers if you want to check out the screen choppy issue.

John,

Good to see you planning the next project. Very organised of you

Speaking of projects Skribs, isn't about time you got a wriggle on with yours

Just because you're building a house doesn't mean you can shirk your responsibilities !
