Difference between CAI and SRI

[Soundofav6]

I have hear tales of something very stupid ....true/ not it's funny.
re direct A/C pipe to their intake !!!!

NOTE: do not direct complains to me.

lol doesn't any benefit from that become removed since your taking out HP to run the air con... wow thats realy stupid, thanks for that

thanks for your comments people.

I have read on forums and internet articles that by having a CAI or SRI will actually be worse in terms of fuel effeiciency.

Something about more air being detected therefore compensating that with more fuel.

Any truth to this or is it a load of crap?

Thanks in advance

Sorry to bust peoples chops but i was wondering if anybody could shed any light on the above? Its really got me thinking

Merry Xmas to all reading.

An SRI is a short runner intake manifold. On a crossflow 2.0 8v, that would mean replacing the 16v-style long-runner manifold (curving over the rocker cover) with a 20vT style intake, which sits right in front of the intake ports, shortening the air flow path, so there is less time for the air to warm up and less bends and distance in the intake path.

It is only worth doing in a turbo car to help remove the lag, or a highly developed NA motor, in which case you probably wouldn't run single-throttle body induction anyway

P.S. All that poor fuel economy stuff is rubbish

Yeah, it's true that the engine management should detect denser air, but because the air is denser, therefore you need a shallower throttle opening to maintain the same speed, so they cancel each other out..
