50mm Inlet Manifold Question???

Hi all,

I have just got myself a 50mm KR 16V Inlet Manifold for my golf and noticed something that worried me! - On one of the end runners on the underside there is a large indent none of the other runners have this.

It actually restricts the internals of the runner so it made me wonder

Is this normal (just for clearance) or have i got myself a duff manifold?!

cheers

 

Its normal mate. I guess its just for clearance.

 

pheww, just looked odd to me because of the restiction.

cheers mate

 

I've not noticed that on mine...

 

You wouldn't on yours , it's probably from some special group A rally car

 

Yeah - didn't think of that!

 

is yours off the ABF tubs?

 

God knows!

 

oh well i'll just get my porting tools on it then stick it on and see what its like

I've got the smallest Inlet manifold on at the mo so hopefully it might be a bit better top end??

 

Should see about 5-7bhp more (at the top end) changing from a small to larger inlet on a 16v

 

Yeah, should be better top end. Will be interested to hear your opinion on what it's done to the lower end torque once fitted..

 

Mines still nice and torquey

Thats what Group A NASA prepared engines like mine do though...

 

will let u know what its like with the larger inlet manifold.

 

Well the 50mm Inlet Manifold has been on a week now......................................................... ..........................................'................. .....I'm SURE its slower!! [:^(]

It's definately a smoother more linear power delivery, which is quite nice... BUT i'm sure its slower than when the small inlet manifold was on there!!!!

Anyone else noticed this!!??

Anyone think its worth checking the CO with the new inlet on?

 

YES

 

Was hoping for power increase not decrease!!!!!

[:^(]

 

Slower bottom end more response top end with 50mm I found.

 

mine feels slower everywhere!!! [:^(]
