Zuffen, By any chance do you have any photos ? I would be interested in having a look. Regards Stephen

MWP, It's not the speed of the air that makes the difference thus the decrease/ increase in pressure on the surface of the object. Zuffen, With what you are saying, i should take my ports out as far as i can go and make the intake tract as big as possible that way there would be as little...

Zuffen, You are right. The longer the pipe the greater the amount of friction restricting air flow, less speed, hence less air. Keep in mind the small distance the whole intake path is, frictional loss would be small in that respect. As for the 50mm restrictor in the Wlkinshaw throts ...

Zuffen, Whilst it sounds practicle and logical it doesn't work that way. What is happening in a manifold is that the port is usually a restirctor, usually. There has been cases where they have got better performance from filling the port as it is to big for the application, such as the VN...

Zuffen, Whilst 80mm doesn't sound that big and the aim is to get as much air as possible, you can only get as much air in as the smallest section area will allow, this is the AFM. The AFM is smaller than 80mm. That and the fact that the intake size has the same effects as a turbo, to small...

Zuffen, Which car is this in ? I pulled out the ECU and other unit beside it 2 weekends ago ? I didn't see anything else with it but i'm sure the other unit was something to do with the ABS ? ( side by side, under the passanger foot rest ). I am refering to the Soarer or SC400. I honestly...

To all the above, After reading this very long thread and having been told the same things as a lot of you are questioning, would it be fare to say that the ideal way would be to match port the lot, mirror polish everything prior to the injectors as ther is no fluid to be concerned about...

Guys, I have heard of the BFI and read Peters page. I thought i would do a little stuffing around of my own with some rubbish i had lying around the place. I removed the air box all together, found an air intake off a 3.8ltr vn commadore ( long striaght with a 90 bend in it ) and used it...

Zuffen, My apologies, I must have read Lextremes post incorrectly ! I thought it said " These fans (first two pictures) are great during heavy traffic. " Would you really have a run between traffic lights in heavy traffic ? One that was serious enough to warrant the thought of thermo fans ...

Peewee & Madmont, I did consider both of your options before doing what i did. Seeing that i had a wreck it didn't matter if i damaged a tensioner or anything else in that case cuase i had a spare. It has been in the car like that for nearly two weeks now a perfect no noises nothing, running...

Guts, Well i tried it myself this weekend and it works perfect. Not sure if the provison was there in the wiring harness, maybe there is an unused plug sitting there ? I was told it runs of its own computer but i have a wreck that i have stripped and i didn't see one, i think it's switched by...

Guys, I think the idea was as Peewee said, merely to stop air temp increase whilst stopped at lights. Personally i don't think it's an issue, unless your drag racing from light to light ? As for the radiator, I am not sure what the optimum temp is nor the thermostat ? I do know that the...

Guys, 1 question ? It is easy enough to rip out the old unit ( hydrualic fan ) and bolt up two thermo switched electric items. What did you do with the old pump that runs on the drive belt ? See i pulled the guts out of it, blocked off both ends and packed the unit with high temp grease...

6SPDSC4, Well the max speed on our freeways is 110km/h. 100km/h= 58-60miles. I have had mine sitting on the limiter ( 178km/h ) 3rd gear @ 5500-6000rpm. Pretty smooth too, other than the annoying sound of the engine bouncing off the limiter ! Still want to see what it will get to ...

Morris, Aparently the American model SC400's aren't speed limited ? This unit is designed for US spec models would it work on *** variants ? Regards Stephen

Guys, Can you change the timing on these motors or is it all controlled by the ECU ? Regards Stephen

5150, I was looking to resolve the same issue. After hearing that some of the guys have tried some aftermarket speedcut eliminators and that they have worked but effected the gear changes i hesitated ? Then after reading many of comments by Americans claiming there cars have been way over the...

Guys, Can someone please assist me ? I have a 1UZ-FE in a Soarer. On the front of the manifoldis a circular object with a water line into it, a line out to the throttle body and a air line from the air intake as well as an electronic plug. I am curious what it is and what it does ? Can anyone...

Guts, Your a smart fella. Untill you have said that i didn't even think about it ! There is a controller for the fan ( hydrualic fan ). I cant remember if the temp sensor switches it or another sensor somewhere else. The system does have it's own little black box controller that controls...
