You may well be right :oops: I know he owned both, but the order could be wrong..... (and he certainly knows his way round Goodwood! :wink: )

Great investigation Philip - just a Ti back box to rip open now :-)

Having run a 1600 CVH with no middle box (and everything else standard), I found it was substantially louder with no noticeable improvement in power or torque? The turbo on a Ti takes a lot of the noise (hence no middle box) - not sure I'd want to run a Road CVH with only a Ti back box? I also cant justify three months of Andy's insurance premium for a manifold, down-pipe and modified Ti sections just now!

For the track however, that manifold looks the mutts and will undoubtably flow better, particularly with a race can and side exit (no axle bend).

Consider that the std CVH rear box is just a "straight through" affair whereas the Ti one is a staggered silencer (hopefully better than the CVH front box though!), then silencing might not be as bad as one fears?

Yup, that's the same Tony Broom who developed the black 1800ti now belonging to Mr Mad

The 1800ti rear section / silencer, does do some silencing on the Ti, but it leaves the CVH rather loud, I shall try and get a video off my friend who had one on his 1300.

Jim, excuse the question, but would I be right in thinking said CVH was not in the first flushes of youth? I regard most unchecked CVH's as smog pumps after about 50k.....

Rebuilt 6k before - unknown spec but it was spritely enough. It was the one fitted here: Image
and was refitted with a full new system, heavily abused for a further 2 or 3 years and only recently removed (still running fine).

Most people would simply jack the car up to show off the exhaust Jim :lol:

That said had it been a 1300 the inherent safety feature (of lack of power) would have prevented such an incident!

Fair enough regards it being rebuilt. Though did it ever actually have a TI system, or a 1600 system with the center box deleted?

Either way, the largest noticable differences will always be felt on cars with the exhaust left as the last restriction, so already sporting a new / uprated cam and improved carburation.

Craig, I shall not debate 1300s with you, after all you ground your teeth on one for many miles as a daily. Perhaps it is this understanding of attaining the most from an SS1s chassis, even when under powered, that makes you so quick today sir :twisted:

Unfortunately, even a 1300 would have rolled in that situation!

It was a standard system with the front box removed as mentioned before.

Can i assume sarcasm Phil? :lol:

ive done many thousands in Ti's but very few in 1300s to be honest, running water seemed quicker. At 280+hp, my SS1 could still have taken more power, it was the driver at fault not the chassis or engine :wink:

as for being quick today, not sure, certainly used to be as records show, but as for today, i will leave Nick K and Viv White to comment as i havent taken a small scim of my own round a circuit for a couple of years against the clock.

so thats my speed sorted, when do we see yours R-R? talk is cheap Dear Boy, and trackdays and drifting have no timing so dont count.

Chop chop :mrgreen:

Oh no! I appear to have a downpipe that looks like RR's trousers!

On a more serious note I havent ever seen one of those original siamesed downpipes before. I am tempted to ask if anyone has one to sell but think I might wait a bit and see if something is arranged -there seems to be a fair bit of interest.

PS. Alan, hope you don't mind me mentioning it but bung a bit of paint or oil on that sump.CVH sumps are notorious for rusting through -usually dicovered when someone puts a jack under it. :)

More pics for this already image-sodden thread!

Escort, SS1 trouser, SS1 original

SS1 OE, Escort, SS1 trouser

Image

SS1 OE siamese pipes inside. Not perfectly formed, but a quick buzz with the die grinder would have it all lines up and smoothed off betweee the 2 pipes.

Image

SS1 trouser. The pipes are a larger diameter, but it's all poorly made IMHO, the exit pipe from the trouser is just jammed in at an angle. If I were to use this top section I would cut out all the original exit pipe.

Sierra 1.8 downpipe through early chassis (pre lightened Craig!)

Don't get your hopes up on the sierra downpipe Phil. I've tried it up with running gear in place, and well, it's no quick fit, just more pipes and bends to add to the pile when building a system really. I think it would be more usefull shuffled clockwise and back a bit, joining on to some pipework from the manifold back.

Bob, admittedly there area few 2minor areas of corrosion"!
Offering to replace it with stainless? ;-p

I have a nice stainless Colander if you need one RR :wink: What I really want to know is are you going to pick up the gauntlet that Craig has laid down? The talk is cheap jibe would have me getting my kit ready :wink:
