Hi Rob. I recently built a similar setup using the SmartWire on Azn's Dung Beetle and it works great. You might want to consider a small fuse and relay block for your ignition (as you stated) but also for the injectors and the ECU itself. You can activate all the relays with one of the SmartWire outputs.

what kind of pistons are you gonna run?

[@jacobwebb8818]

I believe he said Mahle pistons on the 3 rotor and Wiseco on the 4 rotor. Manley rods on the 3 rotor and Eagle rods on the 4 rotor. Rob doesn't know it but the reason the 3 rotor doesn't work isn't actually grape juice, but the knock sensor read wrong and threw the camshaft position sensor off. Can't have it all with variable valve timing I guess.

Fuel Pump wire is to thin for this strong pumps! (2:09)

[@ben94cobra]

for many setups yes. IIRC two 16AWG wires with 20A each will equate to 11AWG/40A which could be inadequate. In these cases just use a single fuel pump output (freeing the other in the process) to trigger a dedicated relay or two.

[@thejman3489]

8:37 A consistent dip and a consistent speed will make it look real nice. Aluminum runs pretty hot and fast and you don't need as much filler as you think you do, especially on thin stuff.

[@CGT80]

That wasn't aluminum; hopefully, you knew that and were just offering extra advice. I have found that moving too slow, with too little heat, makes it harder to get nice beads on either metal. Running hot and fast can help reduce heat input into the part. X2 on consistency.

[@nsboost]

I almost didn’t watch this. I’m working on a Turbo ws6 drag car currently.

Rob Piss the aem dash off and get a racepak logger dash (they can log 42 channels of data) and send all that info over can bus to your smartwire (can control anything based on logic in your smart wire without wiring it all in to either directly the smart wire or a input module) I have the setup on mine and it is outstanding

[@yutub561]

Rob please build up more support on your engine stand. The torque from that motor is going to rip that thing apart and throw your engine on the ground. You've got vertical support for gravity but no cross bracing at all. Also hoping you ground the engine stand properly so you don't short your electronics

Hey Rob I'm not a fan PDMs for the simple fact that if a circuit fails then the entire module has to be replaced unlike a relay or fuse that can be easily swapped out, some high load circuits will take that unit out just a matter of when still a sweet setup for a clean look

With the fuel pressure you're expecting here you really want to have an option to turn off your fuel pumps. You don't want to have fuel pumps running all the time whenever you ignition is turned on for whatever reason (tuning eg)
