In this ep, we get stuck into the mods, we focus most of our time into the intake manifold and creating the external wastegate / screamer pipe setup. To enter to win this GU patrol: www.adventurecorp.com.au
Hi - mount looks siiiiiiick !!! Cheers for the freebies too !!! Awesome work champs !!! Good luck everyone and me !!! Also, what work is going into the driveline? Clutch work, lockers etc.?
It's a little hypocritical that I do recall a video a while back regarding the 4.5L cummins and 4JJ donk transplants that you guys said that you had stopped doing old TD42 conversions due to being old, inefficient and expensive for little gains and here is a series on the kettles and their very expensive marginal power gains. Still can't figure out why simple fluid principles are not understood.... Taking the external gate of the side of the turbine housing would have to be one of the worst things you could do. You are putting a hole in the side of a section of velocity change that really wants to be smooth and laminar to keep efficiency. Put the gate off the manifold and leave the snail alone.
Hi Ben the guru, we aren't doing a td42 Conversion. We are just modifying a td42. You will see in that video where we talk about td42s already fitted to vehicles being a good engine still. Putting a gate in the rear housing is quite common. Are you saying that putting the gate 2" down in the collector of the manifold will have a different outcome? The wastegate needs the priority flow for boost control. If the wastegate doesn't have priority flow you experience boost control issues. The idea isn't to prioritise flow to the exhaust wheel, it's to prioritise it to the wastegate. This is very common in all aspects of motorsport and you will probably begin to notice this now on anything that makes power. The wastegate may not be in the rear housing but you will find it in the bend of the collector in priority positions.
@@adventurecorp maybe but it's a TD42, you're not going to make anywhere near enough power with any TD to justify silly stuff like that. The only reason I can see is the ability to charge more in labour for the same job. If it was me I'd spend the money imo 'wasted' on the external gate, radius fab manifold and hours in labour costs to put toward a UFI pump/turbo or maybe Dc6/Gturbo if in QLD rather than some ebay spec stuff. Then you'll end up spending the same but have far greater performance drivability, until the crank snaps of course. Although most people like cool noises from screamers an painted red go fast bits so I guess for a give away car maybe you are going the right way in the end.
