Which Newman cam for fastroad TR6?

[Thomasmand]

I need a new cam for my fastroad TR6, and after careful reading of Cam-threads on this forum, I have decided to buy a Newman one.

But should I get the 30-70, 280� or the 40-80, 300� ?

 

I want as much Ooomph as possible and favours the 300� but the car must be able to do occasionally town-traffic, so I don't want to overcam the engine.

 

My setup will be:

Slightly flowed head 10:1

Jaguar valvesprings

Lucas PI

6-3-1 + bigbore exhaust

Balanced bottom-end

1:3.7 diff

 

Heard of the new GT cams, but I need the cam soon (summer is coming)(cool)

 

By the way, can I buy the cam directly from Newman to (possibly?) save money, or do I need to buy through my local dealer?

 

Are the standard Newman Chilled Iron Cam Followers any good?

 

All suggestions will be very welcome

you want a cam with lift and short duration - 2.5 don't like long duration cams as you can't run decent compression ratio - so something around the 285/290 duration I'll pm a profile later that I think would do

 

Back when Newman brought out the 40 - 80 as I recall it was one of their race cams not fast road

 

you can buy direct - speak to Ken Newman

 

Why not go for a TR5 - 35 65 profile but with a little more lift - used one on a road engine once on PI it worked quit well

Thanks Mark,

So Newman 40-80 cam is more a 2L profile then?

How about the 30-70, is it more equal to the TR5?  I know the TR5 cam already but would like a bit more topend power if possibly.

Hi Thomas,

 

 

which Newman cam did you finally end up with?

 

just reading through this old thread, with this ethernal question .. .

 

 

Are there meanwhile new experiences with the PH2 (280) cam compared to the 280° TR5 cam?
