[Pics] Exhaust porn

[zuoom]

Got my new exhaust back yesterday. This should cure a lot of my heat issues. Equal length headers, really really nice collector, v-band connectors throughout. The manifold is made of Inconel, all ceramic coated.

It's just generally exhaust porn!!!!



I asked for the silencer to be repackable and as large as possible



You can see the diameter of it here. Bear in mind that the pipe going into it is 3 inch!!

more exhaust porn.

Joe at Prototype Racing www.prototyperacing.com has done some pretty neat work with Honda's K20A. Normally aspirated, with no internal modifications, he's getting 247hp with a pretty flat torque curve. Next up: forced induction and internal modifications.

wa machiam octopus

[criszt]

my god. why so many bends?

[zuoom]

to achieve equal length.

and certain length is required for the tune.

o yes, street name is "octopus".

how come some of the turbines sucking in air unfiltered???

[zuoom]

no filter means less restriction.

less restriction more air.

more air, more fuel gets more bang = more power.

in the pictures, most of them are not completed. can assume most of them cept for those dragsters will be using some sort of filter. the dragsters usually make do with a wire mesh - not unlike those strainer you use in the kitchen.

Then suck in insects and dragonfly leh?? More protein ah??

[zuoom]

Yup. more P --- for POWER! .P

JBS Twin Scroll Turbo Development
We are currently developing a new turbo application for the 1.8T, there are two stages available which with our hybrid turbo versions will be able to offer up to 550bhp, with full boost predicted between 3000-3500RPM depending on spec.


Key features include:

Twin Scroll Design for better response and spool
New More efficient and larger compressor preventing compressor surge
Better pump gas efficiency
Turbine Nozzle Area (cm2) = Large 10.5 hotside, single flapper.
Improved actuator design


A "twin scroll" or "divided inlet" means that there are two separate volutes within the turbine housing. The main reason for doing this is to isolate the pulses coming from each exhaust port and maintain more of the pulse energy from each cylinder all the way down to the turbine wheel. There are no differences between the turbine wheels used in open or single inlet turbines compared to those used in twin or divided inlet turbines.
Generally speaking, a divided inlet turbine setup will respond faster and produce boost quicker than single or open design of the same nozzle area, of course this is dependent upon proper execution.
While it does not cause any problems or harm to run a divided inlet turbine housing on a manifold that is an "open" design, none of the benefits of the twin inlet will be seen.


With this new turbo set up we will be using our ST316SS SC40 equal length twin scroll manifold for optimum performance.


Here is our twin scroll based equal length manifold.

still dun quite get the twin scroll part... can someone translate that to layman terms??
