what the difference between twin pass nd single pass? How does it affect performance? and anyone running a twin pass one?

RichardPON

Bit difficult to run twin pass on a cossie mate - twin pass enters and exits on the same side of the cooler (in most cases)

Switch

not for me Rich, cheers just curious at how a twin pass will perform compared to a single pass intercooler, lets say for example on rst running 200bhp

i think it limmits flow capacity, but i'd immagine it'd cool it better?

Switch

so when ya say limit flow capacity, you mean restricting air into the engine? what will this result in? a boost drop?
I thought the GRS items were twin pass? do u experience a drop with these?

vroooom ptssssh

flow capacity as in how much air it can flow because the ic is split into 2 halfs it limmits how much flows through, pro alloy actually raises boost drop slightly as far as im aware because its so efficient and makes the air more dense, GRS i aitn sure about a boost drop sorry. check out the pro alloy post shuld be on page 2, 3, 4 was on last night.

I thought the Pro alloy one was a single pass?

vroooom ptssssh

it is, i think, was jus saying how efficient it is and has zero boost drop lol

Switch

ahhh, just i know i can source a twin pass for a very good price and need to know if its worthwhile

vroooom ptssssh

aah, well depending on what kind it is, i.e. not pace....... what car is it for and what make of ic?

Ginge !

scott single pass is better mate, but unless its a pro alloy jobby then its alot of hassle to make it fit

canr belive ya not asking me about erst questions

Switch

cause ya was not online? get on msn

Ginge !

bttt for daytime and any one running twin pass or single pass!
