Just out of curiosity what manifold is the best for acceleration on a williams engine,the willy 1,or valver?cheers

I would assume the willy, as it is designed for the engine. Plus the valver one weights a tone :)

i herd the valver 1 was better for accel tho?this true?cheers

Short answer: Considering what a ****ing pain they can be to remove, just use the one you've got. They're both good for factory manifolds

The Clio 16v 1.8 manifold will give you better bottom and mid range torque so yes its better in that respect. The Williams manifold give us better top end power on tests on the rollers. If you fit a 16v manifold you will also need to change the cat or bypass pipe as the joining flanges differ between the systems. A Super sprint fabricated 4/2/1 system designed for the Williams will fit directly to the Williams cat (or by pass). We have a works Sodemo group A rally / sprint engined Williams in the workshop which was built to 230bhp spec that has been built with a cast original 16v 1.8 manifold and downpipe. Says something for them.

ive ran all 3 major manifolds:

16v : ugly, heavy, low end torque, post 60mph rubish

supersprint: looks good, poor design for taking apart, limited spares, break on the down pipe: good performance wise though, especially up top.

Williams manifold, best of both worlds... i swapped to one after running a supersprint and i hardly can feel a difference. i will never go back to using a supersprint, the down pipes jam on and as above the break... plus spares are a pain to get hold of.

ive just heat wrapped and sealed the willy manifold, its great

It depends on the spec of the engine especially, cam profile and timing, as to how each of them effects performance.

i wouldnt mind trying a ss manifold but i have seen markmcgivens which he hasnt had long and the stress marks are unreal for the amount of time on the car, spending that kind of cash for a mod which is designed that poorly doesnt inspire me with much confidence.

I've had a 16v and now supersprint manifold on my williams engine and I think the supersprint suits it much better. The power trails off at the top end with the valver one. I can see why renault went to the hassle of making a new manifold for the williams as I dont think the car was as driveable with the valver mani. I probably would get a standard williams one next time as gunnergibson said. I have already had trouble with the supersprint. I dont think its worth the extra hassle.

I'm sticking to the willy one... just need to stop it blowing now!

I find all this fairly amusing and all a bit handbags at dawn. The williams engine left the factory engineered probably the best it could have for performace and realiability. I also doubt for one minute that anyone on a blind test could tell the difference between them. In my personal opinion why mess with what is already spot on. And really for what might gain you something like 0.005 of a BHP does it really make a difference? Go find something else to worry about and spend you money on.

Interesting...

Have to admit the valver seems very lacking at the mid-high end of the scale. Would changing to a willy manifold improve top end torque that much? (I realise there would be other changes requried, and I could live with worse torque low down as at low revs the engine isn't too hot anyway).

My williams maifold blows like a dog, it pisses me off, sounds shit and causes the car to over fuel. I have already changed the seal once, then the dogbone mount as i thought the movement of the engine was causing it, but no. I dont know what to do now, short of buying a supersprint. Does anyone have any ideas?

Where is it blowing from?

DanClio
15-03-2007, 11:12
i think its blowing from the seal between the manifold and downpipe, really hard to tell as you can only hear it under load when your accelerating. Already changed the seal once, made it better for all of a week.

Any ideas?

id put a guess in that its cracked the weld where the 4 pipes meet. simple grind off n reweld will sort it.

Cool, cheers 2live, will rip it off and have a good look.

I'm fitting the meggy manifold to my willy. It'll be interesting to see how it performs as it's a renault designed stock item for the F7r.

For all those itching to pass comment....I know it won't fit at as standard, but all it needs is a bend welding on, the current lamba hole plugging and another putting in just before it meets the cat.

Just stotted ur post dan....and where the hells the edit button???

Anyway, mines the same mate. I've changed the seal a few times myself and taken it to an exhaust specialist who has got just as pissed off wi it as i have. It causes the engine to run like a bag of shite, frustrating as its just been rebuilt!!

Thats why i've gone for the meggy manifold option. Its a 4-2-1 just like a supersprint one. It needs some minor fettling but it'll go on no trouble. Much cheeper than a shitty supersprint.

theres 2 places that the williams manifold seems to crack under severe abuse.

as said above, where the 4 pipes join into the 1, on the cross of weld inside the mani, this usually cracks away from the metal of the pipe. this is more down to use than abuse tho tbh. they get old like evrything else lol.

grind off the old weld, and get a decent welder to stick it back together, grind/fettle smooth again. no biggy.



the other place , iv had this meself too ..racin a corsa turbo outta york...the downpipe completely ripped away from the joint where it meets the manifold.....the top part of the downpipe was still attatched to the mani by the plate n bolts, but the thinner part of the downpipe had split all the way round and come away from the rest. ...........again..a good welder will sort that out.
