3.0 V6 Cav
3.0 V6 Cav
A few shots of my Cav 3 litreV6.
Main aim is to get it as fast as poss down the 1/4 mile.Currently at 14.4@98mph.
I want to keep it a standard looking as possible.
3 litre going in.
New exhausts i'm fitting
New manifold flange i'm making.

Re: 3.0 V6 Cav
turbo wheels look ace. what's the manifold, one you made? good work, look forward to progress
Re: 3.0 V6 Cav
Manifolds are from a Ford probe V6,made of stainless, bought new off the bay for £130.

No i'm in Rugby, Junc 1 of the M6.
I think Dan saw my car at Santa Pod in october?

Re: 3.0 V6 Cav
yea you parked next to our cars, whats the plan with the exhaust next 2.5" system to match?
Re: 3.0 V6 Cav
Already got a Scorpion stainless system all through with a decat, not sure what size it is?
The Probe secondaries are pretty good in that they are equal lengths front to rear banks, where as the std Cav V6 are unequal. Once the primaries are done i'll move on to these.

Re: 3.0 V6 Cav
they tend to be 2" nothing special.
the exhaust design on vauxhalls tends to be made to a budget rather then power, goes to show what can be achieved

Re: 3.0 V6 Cav
Once again possibly giving egg sucking lessons again but read somewhere manifold pipes should be 110% of cylinder capacity, hope this helps. Allows for best airflow and minimal pressure prior to cat.

Re: 3.0 V6 Cav
There is loads af science behind exhaust pipe design, size and lengths, you could spend ages working out what is best for any engine. I think these pipes are probably too short, an engineer at work reckons 600mm would be about right, failing that go for 300mm which these are.
The sizing is a compromise between being too big which will give you high flow, but low velocity and too small will be restrictive but high velocity. The port size on a V6 is roughly the same area as the 1 5/8 dia pipe in this system so that persuaded me it was about right.Looked at a load of stuff on yankee websites and they would tend to say 1 1/2 was right, but that looked too small to me.
Also much depends on packaging it all under the bonnet, 600mm pipes may be good,but they would end up being more expensive to make. I might look at this though once i've made this set.
However, I think that anything has got to be better than the standard manifold.

Re: 3.0 V6 Cav
you're not wrong, the stock v6 manifolds suck. if you'll excuse the pun.
Re: 3.0 V6 Cav
This is where i have got to so far with the flanges.This weekend i'll remove some of the excess material.
Re: 3.0 V6 Cav
Looking really good, i suppose im spoilt having an xe as you can pick up flanges off ebay/forms really easy
Re: 3.0 V6 Cav
The completed flanges and the first pipe tacked in.
Re: 3.0 V6 Cav
Front manifold almost finished.

Re: 3.0 V6 Cav
nice work, but thats a lot of cak on there!
Re: 3.0 V6 Cav
Its only a spare engine I've got on a stand in my garage.But yes,it is covered in cak

Re: 3.0 V6 Cav
phew! for a split second i thought you were fitting those shiny new manifolds onto that filthy old lump and then sticking it in the car haha!
Re: 3.0 V6 Cav
The completed front manifold(minus crud covered engine)
Re: 3.0 V6 Cav
Finished my manifolds, just the downpipe to do.
Re: 3.0 V6 Cav
They look awesome...

Re: 3.0 V6 Cav
Very nice mate.
Re: 3.0 V6 Cav
Finally finished the pipes,hopefully get them fitted next weekend.
