Wedge List / Re: TR7/8 Digest V1 #9207

Willbs spot on.  Minimal gains from just CR bump, however if you combine
that with the wedge shops tq20(great cam) intake headers 4 barrel carb etc
they typically make around 250-260 at the crank (plenty of dyno videos online
of their engines).  Head work, larger valves, bigger cam etc increases those
numbers.... sounds like a fun route, good luck!

You wonbt see much gains just from a bit more compression.   A better cam is

really needed.   Head work also really helps with these engines.  Ibd

recommend the wedge shop for a cam.  My favourite is the Erwin TQ20

Hi all

My TR8 is originally from Michigan and therefore has a CR of 8.13.  I am in

the process of upgrading the engine and have purchased a set of 9.75 pistons

from Rimmer Bros.  These are oversize by .020b as standard size is nla and a

rebore is planned.  I expect to have to change my timing accordingly and

wondered if anyone who has made this upgrade could suggest what it should be

set at.  What could also be interesting is just what sort of performance gain

I could be looking to.

Any help appreciated as always.



Leslie

The harmonic balancer and its markings are fine.  Itbs the little finger

bolted to the timing cover.  Once my engine cooled off I was able to find it

bent up and scrunched.  There are two bolts that hold it to the timing cover

or something.  So I tried to straighten it, but it just fell apart in my hand.

Woody has a new one.  Two bolts b four scratches on the back of my hand, and

Ibll be good as new.







I had an A/C belt break sometime back.  Must have been the whiplash of the

broken belt that smacked it and tore it up.

If your car is a TR8, Woody sells a new timing pointer.B B  Is this what you

need or are you missing the marks on the balancer?

This is so weird.  I went to check and set the timing today and the index

mark to line up the timing marks from the crank is gone!  I just can't

imagine what has happened to it.  No work that would interfere with it,

knock it or otherwise disturb it has been done.  So I have no idea where to

index the timing to.  This is an FI car so the proper timing is 0 degrees

BTDC.  



 



I notice there are a couple bolt heads from the water pump nearby, could

someone please give me an alternative index?  I.E. when 0 at the index,

where is the right (or left) side of one of those bolt heads.  It won't be

sticking out to the timing marks like the index finger was, but it will get

me close.  Alternatively, some other method to dynamically set the timing.



 



This is so weird.



 



Thanks.
