How do u work out how big they should b in respect to engine capacity!?

also what sort of thickness metal is best!?

also what sort of metal!? ally, stainless!?

 

dream dream dream

 

LOL

Been thinkin about it for a bit!

am board now mist things r done on the car need soemthin else to waist time on!

 

The optimum design is not trivial with forced induction... If you find one, please tell me.

 

kool!

so just big then! lol

 

no mate no at all, too big and you gain lag, and will get a pressure drop.

there's always an optimum size

but then again its all based on engine spec etc etc

but there are general rules of thumb to follow

 

how about spending some time reading a dictionary?

 

nah fook that bristolian we got r own language m8!

 

The monkey language?

 

nah not even the other MMS members can understand me!

 

I've always wondered about this - exactly how important is it to get the correct amount of air to each cylinder?

 

obviously if you've got bling manament, i.e T2, SESC, Autronic, etc You can have fuel trim, but obviously for optimum performance i would think you would exactly the same amout of fuel and air into each cylinder to create a indentical combustion.

 

i would of thought that each port would need to be equal in size and performance other than that i have no idea

 

Back in my Formula SAE days, I had a discussion with Paul Gentilozzi (yes, that PG) and he commented that a plenum should be 110% of the engine capacity in volume.

This generalization seemed to work really well on the cars that we build subsequent to the discussion with PG as we set new records for HP and Torque using M85 (basically methanol)

The manifold that I made was basically a flat floor with 4 holes in it for the individual runners to each cylinder. Pressed and welded into the holes were basically velocity stacks that were fairly short. The 'roof' of the plenum tapered down from the inlet end to the blocked off end.

Worked great and was not all the difficult to fab.

 

fook me

can someone be my translator whilst i am staying with lewis?

 

no

 

your on ya own rene


they i would if you bring ya misses

 

gwaaaaaaaaaaaaaaaaaaaaaaaan

 

 

HAVE A LOOKY AT AUSTINW'S INLET IN THE PICS BIT.

PROPPA BLING.

IM USING 4MM THICK ALLY SHEET FOR MINE

 

yea have gotta chat with austen!
