your filter is post 13 could be much bigger than it is as there is plenty of room.

 

Crikey - do I need bigger? That's quite big already

 

ive always come to the conclusion that the bigger the filter you can fit the better,and the more cold air you can get to it the better,you could fit a filter similar in length,maybe a little longer but quite a bit wider and have the funnel filter(the one with the hole in the centre) to maximise the potential of cold air flow.(hence why i want to shorten the maf pipe and put a BIG filter in.

 

Hmmm....

 

so after all your doubting my plan.......

 

- you groomed me for that hit

that set-up is still a compromise, unless you can completely isolate the filter from the rest of the bay. Wheel arch system is still the best

 

yes but is it really necesary to worry that much?,surely it will be loads better than the sti 4 tmic i already have?
my brother is a wiz at stuff like this so ill trust he will think of something good,after all im only looking for 320bhp or close too.
alot of people dont even have partitions at all,some dont even run a cold air feed and still dont have any probs,i think we will still fit a filter in the engine bay,but it will be a big one with a 3" cold air feed directly to it from bumper and possibly a partition,(not sure wether to or not tbh). im sure that will be good enough.....if not then my mapper would not have advised this route...surely?

 

True enough - I think cold air feed seems a subject not covered much on the forums. I know Harvey has done work on bringing it forward

But remember, I had ACT's of 41° with my set-up...

 

excuse my ignorance but what should the ACT be roughly?(with similar set up)?

 

I'm only getting this myself now as it's an issue with wmy running. It's not so much a temp to aim for, nore how much more the ACT is than the ambient air temp.

On a road mapping session with the std WRX top mount ACT was 40° when ambient was a recorded 12!

RR session ambient 26 (guess), ACT 41, temp at air intake 50!

 

ive been looking at bhp capabilties of filters and your filter looks way too small,this could well be the reason you have high temps.when i get mine done ill post some pics up.

 

got this hks mushroom kit for sale if you want? i sprayed it red and made an adapter plate. i had an induction scoop. worked fine, sounded good, got 15bhp more than a same model scoob with similar mods but no i/kit.



this is the only pic i have of it fitted, sold the car now. (98 uk turbo)


can have it for £35 delivered if you want it?

 

thanks mate,but been advised not to use hks,going for a larger filter.
