B-Man

Ha ha - I just watched the SBS story. Fatz got awared tool of the meet award for some major sideways action and very petite reverse entry into the Motokhana finish Saw some SAU ugly mugs too.

I can't make it now - I hope everyone gets some good gear.

I am very mis-understood

Sorry, what I meant was that the forms that I collected got to Shell, the info packs and stickers went out and the membership process worked..... I didn't mean to say that I was the only reason that Scott and Sam joined. Of course I wasn't My bad - I shouldn't have said 'recruitment'

Yay - my recruitment process worked Welcome Sam, Anthony !

Oh - was this tonight ??? Whoops - oh well, they probablly don't let 5 year olds in anyway...............

Whoops - you posted to quickly Matt. V.Interested to know how you go with this

Jeez Rhys - You got me big time - I thought you meant 180SX. Not 180B. Still - go the SR mate - wicked

grey imports = tops

:werd:

Good Shite ! Are you gonna transplant the SR ?

I reckon Steve has the right idea with the 3037s pro

Ha ha ha Not a good day for b-man today...... Car has been intermittently not starting recently - seems to be when I leave the ingintion on but not running for like 5 mins - leave it for an hour and it's OK......... ( ie seems heat (electrical not engine) releated) Now the damn thing won't start at all now - so I changed over to my stock ECU and starts every time - but won't rev past 3000 RPM (no AFM) - so I reckon my ECU is stuffed ........ fark it ! And to top it off - I scratched the shit out of my rear left wheel today on the gutter - some prick parked me in - I farken hate that... Far Canal.

oh, oh, oh - my new job - car durability tester - I'll do that for free

The origial clutch I smoked real bad wasn't a UAS clutch Chris - it came from another workshop. The UAS one is similar - but stronger clamp load for my setup. It still doesn't hold 3rd and 4th with 330rwkw on the drag strip (little slippage) , but Is OK for circuit. It will be fine in Sam's car. When I wear this one out - definitely going a twin or tripple.

Same

Steve, I don't think the larger AR on the exh. housing makes that much difference to lag - Look at Doughboys' chart and mine - he is running a .79 and I am running 1.12 - Lag was about the same, if I recall. (Both HKS 3040s)

Who administrates the administrators ??

Why did they change it from Saturday back to Wednesday ?? It's so hard for me to get there on a week night.....

Ben, I have never heard a bad report on the performance of an external gate - they are pretty simple devices. (yet expensive) Known Brands are: Trust / GReddy TIAL TurboSmart HKS

Posted last Sunday, Sorry it took me so long.

What's the difference between internal and external wastegates? Internal wastegates are comprised of a flapper door which is built in the turbine housing, usually operated pneumatically by a mechanical actuator. These flapper doors are limited in size, but work well in certain applications. Usually found in smaller turbos, internal wastegates are relatively inexpensive, simple in design, and very durable. Larger turbo can be fitted with internal wastegates, but boost control can be tricky. If you are looking to run high boost (20+ psi) all the time, then an internal gate may be fine. If you are looking to run lower boost levels, you will need an external wastegate. External wastegates are generally mounted to the exhaust manifold or to the O2 housing, and are self contained units. External wastegates have the ability to bypass large amounts of air, and can provide steady boost control at any pressure level. A common myth is that in order to run higher boost pressures, you need a larger wastegate. This is incorrect. Larger wastegates are necessary to run low boost levels on large turbos.

More good info here: http://www.atpturbo.com/root/technicinfo/gendef.htm http://www.turbofast.com.au/

A wastegated turbocharger includes an integral device to limit turbo boost. This consists of a pneumatic actuator connected to a valve assembly mounted inside the turbine housing. By connecting the pneumatic actuator to boost pressure, the turbo is able to limit its maximum boost output. The net result is increased durability, quicker time to boost, and adjustability of boost.

See this turbo housing ? This is the exhaust side See the little circular flap and actuator arm - this and example of an internal or integral wastegate - In other words, it's integrated into the exhaust housing Here's another pic of a housing with an internal gate Internally gated turbo's require an actuator to open the gate: This next pic is an example of a turbo with an external gate The wastegate is mounted on the exhaust manifold. Here's another The actuator is built into the external gate.
