jenvey ITB manifold - megane vs clio difference ??

[EVOgone]

The port sizes are different on the F7R megane and the Clio but on the jenvey drawings it shows them the same size?

What are the options for an ITB manifold for an F7R Megane head?

 

[Laine_16v]

Chadil (if you like waiting and waiting, and waiting some more), or theres a new place makeing a manifold for them i believe, group buy on C16valver.

So does the Jenvey Megane manifold create a big step when mated to the head?

i was going to use this guy as he makes all his own stuff, and usually cheaper than jenvey ect

There was a group buy started on here too via 16valver.....

Steel...! Want an ali one....

So back to the question if the 172 ports are bigger than a megane (albeit same profile) will the jenvery manifold leave a step as the drawing indicates that the port shape is the same size ?

I showed you the difference in this thread >> http://www.cliosport.net/forum/showthread.php?680176-Inlet-ports-172-F4R-vs-Megane-F7R

not sure best to pm Fred or Dan as they are the men with the knowledge of both

So there is a big step with the megane jenvey manifold not a good design? Not very good as there drawing shows the ports as the same size...

The meggy ports are small than F4R as shown in pics, i grinded out the manifold to adapt it to fit (was on my Meggy F7R beforehand), you can port match it well enough but i could never get it to seal well because the manifold bolts holes are all in different places.

IF Jenvey show F4R and Meggy F7R ports as the same then they have false data. It's close, but theres no cigar in sight.

Get the Jenvey one all day long

You're basing that on chadil parts which are at best passable. I've put an f4r manifold against an f7r Meg head and its very close apart from bolt holes. I think your chadil miss match was offset to one side. Centralised it would be far less dramatic a difference

Certainly a valid point!
