I shouldn't think so. Pulse width speed controllers work by pulsing the DC power on and off at varying duty cycles. Much like the way the injectors work in your EFI system. The longer the injector is on for the more fuel flows.

The longer the pulse of DC power is on for the faster the fan goes. The fan has some inertia so the pulsed DC doesn't make the motor stutter or any thing.

A VSD is used on 3 phase motors and works by changing the frequency of the 3 phase power to change the speed. Pulse width controllers are for DC motors

thanks Mike... was the issue I was concerned about from prior experience with 3 phase speed controllers in commercial applications.

Current build update.. AC sheetmetal finally in.. !! and wasn't it fun the third time.. Condenser mounted, sheet metal trimmed flush and reinforced.


Second matter.. The US guys have a number of suppliers of headers that suit the Coupe / Roadster, with the primary collector positioned in front of the end of the footwell.

Any advice on Sydney or Aussie suppliers of something similar or any recommendations on block huggers etc would be appreciated.

Cheers

Hi Chris,

My Daytona from Daytona Sports Cars, Dromana, Vic, has a similar exhaust set up with the primary collector positioned in front of the end of the foot well and also using a V Band clamp. From there I have a 90degree bend to Cat and mufflers. Mine is a 2 1/2" system.

I have attached a photo which shows you the set up.

If interested in more details, PM me.

Cheers
Theo

hey Theo.. as per our PM's, no joy with Daytona selling the headers (just yet), will chase them again tomorrow..

Test fitted the body yesterday... had to cut about half the lip off the back and curves out of the corners for the tank.. is a well known issue on the build forums, has been cleaned up and ready to go for next time.

Cheers

Chris
