Hey,

First off, will fitting a ram pipe give me more power than just fitting a K&N filter (this type) ?

And on a stage one 998 which would i need, a long or short one?

And will i need to modify my bulk head to get it to fit and allow clearence for the pipe and air flow?

And one semi related question, Which needle is needed on a 998 with a stage one kit?
I havent actually bought any of it yet, but i will be buying maniflow parts so it wont be a kit.


Thanks

Chris

I can tell you its an AAM needle that you'll be needing...

My stage 1 kit is running an AAA, some kits come with an AAU or an AAV needle, need to be rolling roaded to get the optimum power

As for the rampipe/K and N filter, you will need both, a carb doesn't like a 90 degree bend as it messes with the air flow, that ramstack should go inside the K and N filter (im assuming that its a stubstack)

That K and N filter will fit any Mini, its only the pancake style ones that have clearance issues on the centre speedo minis (like mine) due to the speedo cable being there.

Yes a ram pipe will help, but you need a short one or the filter will be too close to the bulkhead, if not hitting thou.
About needles, AAM or AAA will be good.

can you get these AAM needles from ebay? because i cont seam to find any on there....

[m1tch]

I did see some on ebay a bit back when I was looking for mine, but its probably easier to go on minispares to get it, which is where I got mine from as well

AAM:

AAU - supplied in their stage 1 kits

AAA- what I, and many other are running

Also check out this online app to check the difference between the needles (AAM seems to be twice the price of the AAU or AAA lol):

I cant get to minispares now though till 2 weeks yesterday....

The AAM needle is only slightly richer than the AAA, so perhaps find an AAA as they seem to be cheaper

You won't notice much difference with or without a ram pipe. On my 1293 rally Cooper 's', it gained about 1.5 bhp at 6400 when the stub-stack ram pipes were fitted inside the K & N filters. I was quite disappointed. Maybe if 3" long, or longer, ram pipes were fitted the improvement would be more noticeable. I can't say they improved mid-range torque either, but my car is so 'cammy' I possibly wouldn't notice anyway.
Put it this way, it can't hurt to fit them.
As for needles, the expression 'Stage 1', really doesn't mean very much. It's a widely mis-used term for a minor set of tuning mods which differ from one 'stage 1' supplier to another. It would be more help to you to call a rolling road company, like Peter Baldwin, give them the actual specification, not just 'stage 1', and ask for their advice. That will get it running, then you need a rolling road session to set it up accurately.

Tell me if ive got this right...

I will need to modify my bulkhead to allow a ram pipe to fit and get enough air flow, and i will need a long one?

This wont be much of an issue i think. from what i can see the ram pipe would just go straight through the existing hole which is coverd by a plastic blanking plate, which i could replace with a home made version.

And im best off phoneing a rolling road place for the needle advice?


I know a ram pipe needs a filter i think they call it a sock.
I was asking if i would get better performance from a ram pipe set up instead of just the normal cone filter that most people use.


Thanks for the help guys.

Yes the original ram pipes gonna be used with a sock filter.
You dont need to modify bulkhead to fit that kind of rampipe, for HS4 carb they are 2,5" long.
You need more clearance if you want to fit a long 'stub stack' rampipe for a K&N cone, but, as above said, you can even fit the stub stacks inside the filter, then u'll have no issue at all.

Its only really when you heavily upgrade the carbs to say a Weber will you need a bulkhead box, simply to fit the larger inlet manifold, fitting ramstacks won't need any modification

[jaydee]

Actually the problem is that there isnt such a good airflow near so close to the bulkhead, thats why many of us are using an airbox casing or an a long air intake to route airflow from the front grille to the air filter.

Can you explain that a bit better please, i dont quite understand what your saying


Thanks

[jaydee]

Oh you're right. You can even use a longer stubstack which fits inside the cone filter, and theres no need to modify bulkhead, thats what i mean. Sorry its bit late and i'm old..
