350I camshaft spec

[chris59]

Hello guys and Gales,

I have to built an engine for my LHD TR8 coupé, and would like to create something with the same character as my 350I' engine.

So, the first step would be to find the camshaft profile, then the modifications to bring to the heads, find the right model of pistons, the list goes on and on....

This TR8 3L5 engine won't have the same injection system, neither SU carbs : I'm thinking about an injection who loks like a 4 barrel carb, what's your opinion ?

I want to built a road car, not a race car : imho, the 350I engine is perfect in this role.

This one ? http://www.v8developments.co.uk/camlongstealth.htm

Is there a way to find its profile, as the profile of the 350I camshaft, as I would like to compare ?

Give them a call is not an option : I'm not native English, it's far more easier to write and read than to speak

Hi, thanks for this, but without knowing the profile of an original TVR 350I camshaft, it's difficult to find the right one for my project.

Is this profile unknown ?

Thanks to both of you guys.

Adam, if ETC6099 is the cam originally fitted to my 350I, allowing it to deliver about 197 hp, I think ERC2003, as a factory fitment to TR8 (with carburettors) is a "softer" cam : my first TR8, who was 100% original, was far less powerfull than a TVR 350I.

I'll follow your advice, and ask to RB if they have a datasheet for ETC6099.

Update : just to confirm that ERC2003 is the original fitment on a TR8, with 30/75/68/37.

It's a very "soft" cam compare to the one in a TVR350I, who's a shy more porwerfull than a SD1 Vitesse, who might be ETC6099.

The plot thickens! I'm sure more will come out of the woodwork.

Also note that the EFi has an effect on driveability too (as opposed to carbs).

Another point is: what is your mileage on the 350i? Because cam lobe and lifter wear can soften the original over time, just a little.

I'll have a look at the Mileage this afternoon, Adam, but this 350I is pulling very seriously, so the wear, if there is any, must be unsignificant.

About injection, that's the reason why I talked about a "false" 4 barrel carb, in fact an injection system as sold by some companies (iin USA if I'm not wrong), or, eventually (I think it do exist ?) a pair of SUs lookalike with hiden injectors.
