I made an observation. Get over yourself jay.

I don't care what anyone else says, but the primarys are too small on off the shelf extractors; they whip up what they will be able to sell without doing any dyno testing.

Why have they made the primaries 38mm for the fwd KA24E, and 42mm for the navara with the same motor, going off their specs on that page? Even the secondaries and outlets are larger on the navara KA24E than the U12 KA24E.

You call that abuse?

FFS, the retard level is abnormally high in this thread.

Tell me this jayjay, since you know SO MUCH about the KA24 and header design.

Why fit LARGER primaries, secondaries and outlets to the SAME engine, but in 2 different chassis's?
And the layout of the engine HAS NOTHING TO DO with the answer.

That was a response i made as provoked by yourself.

I was *trying* to contribute some form of technical discussion to this thread, not "what brand of the same extractors should i buy" type post.
You might have been a member for the last 4 years, but you certainly haven't contributed shit.


real good moderating skills to mate,  lets see if you can be abit more up yourself

I don't care what people think of me or my attitude.
The people who have met me in person, or who have dealt with me via buying or selling don't have a problem with me.

All the crap is being removed from this thread in 2 days, to bring it back to what the thread was about in the first place.

im sure the companys that make these extractors would like to hear you negative and judemental accusations of their products.
all i see with you is a lack of respect for people of these forums.
thanks to you spiteful remarks i will be leaving these  forums  and i wont be suggesting that any cutomers use them.
a dissapointed jayjay.
Check it out, it's like this. If I lose, winner takes my happy meal. But If I win, I take the burger AND the TOY. To some people that's more important

i can't wait to watch your karma drop.
Don't let the opinions of the average man sway you. Dream, and he thinks you're crazy. Succeed, and he thinks you're lucky. Acquire wealth, and he thinks you're greedy. Pay no attention. He simply doesn't understand.

to be fair, it wouldn't be ANTRX if we stayed on topic.

and if someone wasn't cranky at Chr1s for something he said...

I'm only digging this up from the dead to make a technical observation and comment on why off the shelf KA extractors are crap, for those that may be in the market for them.

Working on the new airbox for my brother's DC2 'R last night, and decided to get the verniers out to measure the OD of the primaries on his aftermarket headers (i think they are JUN? that or Spoon).

44mm in diameter, inner diameter is probably only 40.8 as (i think) they are 1.6mm thick stainless tube.

Now, at 38mm outer diameter, my genie headers would have to be 2mm wall thickness if not more, as they are mild steel. that leaves us with 34mm inner diameter primaries. :(

Quick calc in excel using the formula for approximate mass flow through the engine, cfm = cid x rpm x ve / 3456 reveals some interesting facts.

At 8500rpm, the B18C7 in his 'R, assuming a REAL good VE of 106% (possible; engine inhales 106% in each cylinder, equivalent of 1 psi boost theoretically), approximate mass airflow out of the engine is 298 cfm.

At 6500rpm, assuming at best a VE of 93% (-1 psi vacuum), a KA24E will churn out approximately 261 cfm. Bump your rev limiter to 6750, 271 cfm; with a noss special stage 3 rom, at 7000rpm you'll be moving about 281 cfm (theoretically, your VE will probably drop quite a bit after this point though).

In any case, 38mm OD primaries in aftermarket KA headers are too small for any kind of mid to top end improvements.

Don't even get me started about poor collector design on these things, this is the most crucial aspect to obtaining a decent scavenging effect from a set of headers.

But the average Joe, which they are designed for wouldnt know or understand what you just said and they just want it because common knowledge is adding extractors is a performance enhancement and you will get gains from it.

Plus they're fully sik

True.  :)

I think noss had verified that extractors were only good for 2 odd kw's at the wheels?

yeah somewhere around there. I thought it was 4kw but either way its minimal.

But its common knowledge that people think with an exhaust you need extractors to make best gain. Which is why they can produce crap and still sell it.

Spot on mate.

I'd still like to see what gains can be had on a KA from a properly designed set of headers, might add it to the to-do list and chuck them on the daily driver.
