silly Q really...

when moving from a nrmal sized throttle to a larger one (eg changig from RSt one to cossie one) does the car require a remap etc.

i THINK the answer is no as surely it wouldnt flow and more air at the same boost, but thought i'd ask just incase as i beleive i may actually have a larger dia TB than a std item on my XR4 and would like to keep this

 

why not get the car remapped anyway, just to get the best from ya car

 

not that simple on my car

 

do you think you could gain anything in having a larger throttle body?

 

Anbody know as I was going to use a 2wd cossie one on my rst?

 

why jim is it the same as the rst

oh and mktart dont think its needed on the rst tbh, but they do look better though

 

b19bal - Who's mktart??? Ain't that someone on a cruise forum I ain't a tart either ya slag

 

sorry never read it right

anyway you get the point dont ya

 

really anything that could gain hp needs a remap!

 

no but my boost hoses fitted on my old throttlebody and not my new one... lol so it must be bigger... want the bigger one so the hoses fit

and its SOOO dissimilar from an RSt one you wouldnt beleive it but was just using an example of wat i was talkin about

 

Your airflow meter will calibrate it untill it reaces its limit at WOT Jim.

Try her on the rollers

 

i forgot it had a metering head

 

my airlow meters shit themselves on boost stu hence the extra little DCU thingie...

and gereth, it has 2

 

The restriction is general the inlet tracts /valves, so id not worry too much.

But if they ARE the restriction, why change the fooker in the first place Jim? What ya up to now?

 

update, the throttles themselves are no bigger, theres an outer metal sheath over them where the hoses clip onto to allow you to get a proper bit of hose on there... THATS why my hoses didnt fit properly on a std throttle

all makes sense now

so the question is pointless still was nice to know the answer mind
