50mm inlet fitted today on 1.8 16v

Following on from gvks results using a 50mm inlet on his 2l i decided to try one on mine again.
Took a dremmel to it first and took loadsa metal out around the throttle body area including a huge lump blocking no1 runner and match ported the 2 halfs together.
Took it for a spin and it feels like i havent lost any low down torque but just gained from 4k upwards! Now i dont have hard dyno evidence,im just stating how the car drives after the modification

 

the 50mm works well on a 1.8

 

lol- wonder how many more people will ditch their 50s after seeing my graphs..

 

Think it might be a bit mis-leading,as prof says,it seems they are better on 1.8s

 

Why is it mis-leading? If I said jump off a cliff would you?

 

......as he goes looking for cliff
What i meant is people with there 1.8s will now think 50mms are pants and change em cos of your graphs,thinkin they only gain 1bhp.
Remember i live on the isle of wight and am surrounded by cliffs

 

But the graph is of a 2.0 ???

 

I think what flusted is trying to say is that people are taking garys graphs as gospel, and after seeing it, everyone has now decided to ditch their 50's for 42's (not that thats garys fault of course). Thing they dont realise is that the 50's will work differently on different setups, its just that garys setup favours the 42

 

PING! CORRECT!

 

Spot on Smithy

.. when I had the Schricks in and a small inlet I only had like 2bhp peak more than it is now

Fecking 16v's

 

just go with the "if its bigger its better" it works for novas

 

I did, and look where it got me

 

50mm works for me, anyway 42mm only works on short arses cars

 

I will not be ditching the 50

 

I`ll stick with my 41mm

 

talking of inlet manifolds you will need a performance gasket to improve power,I give you the riser

Doesnt the hot outer manifold speed up the cool air inside? wheres all the science teachers?

 

can't see that gasket doing any harm but it will alter the overall tract length slightly

 

These gaskets are snake oil.

The engine will still generate the same ammount of heat. Assuming the gasket works as well as they say ( fuckwhits can't even spell "detination" ) what you're doing is removing a large alloy heatsink from the side of the head, where's that heat gonna go, Portland, Oregon for a holiday?

 

Best way of keeping the inlet cool is by removing the bracket at the back for the throttle cable - that gets red hot when been run...
