exhaust header

[tdiplc]

Blimey!!!!!!!!

That essay on the Swift contains an aweful lot of hot air - if you'll excuse the pun :)

Ehem.......n/a engines do not rely on air pressure to fill the cylinders, they rely on the suction created by the downward stroke of the piston on the induction cylce. That is why any type of removal of a restriction will generally work well providing there is sufficient exhaust flow to cope.

Regarding the exhaust, generally the lower the back pressure the better in n/a, turbo or supercharged applications. In a turbocharged car there should be minimal back pressure between the exhaust valve and the turbocharger as this restriction is basically lost energy which translates to higher cylinder temperatures, lower boost and slower spool up time. There will always be some back pressure here because the turbocharger itself creates a restriction, but that is the only form up restriction you should have if possible.

Supercharged, turbocharged and n/a engines all benefit from having correctly tuned exhaust pipe dimensions. Who remembers the glorious Formula 1 turbo engines with their amazing tuned exhaust manifolds? Fantastic stuff!! The main reason that they are not in common use is due to the cost and space implications (and some people don't know how to make them).

If the pipe diameters are too large the gas speed slows down which loses torque - nothing to do with too much air flow as mentioned in the Swift. If the pipe diamter is too small there will be a restriction. A good ananalgy is blowing down a straw and a drainpipe. The air esapes from the straw very quickly, but you won't even feel it out of the downpipe becuase the gas speed is too slow. The pipe lengths are critical due to the reversion pulses that exist and can be used to scavenge and various rpm's

The manifold we have made has the correct lengths and diameters to suit the is200. Sadly it is a complex design (as you will see when I post some pictures) which means that it ain't gonna be cheap :(

That's burt up a few minutes - better get back to work :)

How long before orders can be taken, or will it be a Grim wait(pun intended).

1. Will the compressor have to be removed for instalation

2. Will we need a new heat sheild.

will having this reduce the life of our CAT.

cheers mark.

Hello

Price and power are to be advised.

We will not be offering this header as a self fit because we cannot find anyone capable of mass producing them. Trust me you will not want to put the heat shield back on. You will see how sexy they are soon :o

Mark :)

Mark,why can the manifold not be a self fit........:?:

[superchargedmorph]

On a standard IS300 170bhp, when fitted with a injen intake, Apexi AFC and the toyomoto header it will get 200bhp.

Just a question, is the reason for it not being self fit because the air sensors into the cat have to be changed as no precats and different output.

[tdiplc]

The reason that we can't offer them for self fit yet is because they are too complicated to have them mass produced, so we are going to custom make them on the car. That's the plan for the moment anyway unless anything changes.

Cant wait to see some piccies and performance figures:yes:

Mark.

Have you guys got 2nd jobs designing flume rides at water parks :o

Lets get this 'straight' .... errr

Your manifold releases SO much power, only 5 of the 6 cylinders need connecting

And i thought they were taking the P when they said ....

Pipe bends ... 'Buy 1, get 2 free' at your local KwikTwit now :smilegrin:

Just teasing :P

Are they equal length to collectors ? No.2 looks too short ...

Or maybe an optical illusion ...

Oh, Keiran - looks like someone stole your compressor :(

I'll get my coat ... Night ...

ran out of cash so only connecting 5 out of 6 for now. mark has pawned the supercharger so the final one will be done soon :tumble:

The HKS header on the 4 cylinders Altezza produce good result. I really hope that HKS will produce a similar header for our IS200 (GXE-10) as the market in Europe & asia is justifiable.

Presently, I am using the AUTOFIX header for my supercharged IS200 and is very satisfied. For more info on this header, kindly contact AUTOFIX at autofix@pacific.net.sg

[asinn]

how much power are you getting out of the header?

is the header similar to the TDI header?

and how much is it?

do you have a pic?
