Aussie Ferrari Spotters Thread??

They're a very good Jaguar or Mercedes.

Can the fibreglass body twist and crack when the chassis is bolted down on the dyno?

 

Turbo ECU?

 

Oh good. You can read.

 

ECU made by Turbo......

 

no more than a steel body would.

 

=a lot OLIO

 

A steel body would crack?

 

the paint might, you can flex metal a lot before it cracks, think of your aircraft wings

 

No. Chassis twist occours in cars with front mounted longitudonal engine and a rear driven axle. The torque of the engine (can ) twist the chassis in relation to the differential.
But all 308's have a transverse rear mounted engine, so no lengthways twist of the chassis possible. The torque of the 308 engine is transferred to the rear frame of the car with a torque arm from the top of the rear cylinder head.
Also 308's have steel tube frame chassis which ties the suspension and mechanical components together. The body (whether steet or glass) is not a structural element, it's just bodywork to keep wind and rain off the occupants.

Some front engine V12 Ferraris, for instance the later 275's and the 365 /400 /412 series are fitted with a torque tube that ties the engine /gearbox and rear differential together in to one solid unit, thus eliminating the torque reaction to the chassis.

 

Hence the torque tubes on the later 275s

 

Sorry Mike, the torque tube is not there to eliminate the torque reaction, it's to ensure constant alignment of the transaxle to the engine.

and trust me, a Daytona with a torque tube applies plenty of twist to the chassis when you have it on a dyno.

 

you have no idea.

The early short nose 275's had no torque tube and suffered driveline vibration because of the independent movement of the rubber engine and transaxle mounts.

Torque tube was introduced to solve this problem.

 

I know exactly what the torque tube was for , got all the books on the cars that had them and what you say about the vibration is right but the vibration came about because of the torque reaction from the engine which cause alignment problems with the transaxle hence the torque tube maintained that alignment eliminating the vibration ... where do you think the "independant" movement came from ?

 

Nice car, mate.

WTF are you guys torqueing about?

Dunno WTF is going on here

OLIO...

 

Yeah I tried to buy my 355 headers directly off them in Taiwan....They said they couldn’t do that and I would have to go through their agents in the USA...

 

That's odd if they're advertised for sale on alibaba

 

What did you end up doing Gaz? I need a set for mine

 

Was about 3 years ago PP...

 

Bought a brand new set off one of our Fchat members in the US who never put them on his car before he sold it Gizz...

 

Good work mate! I'll keep scouring the classified ads.
