Lx450 bullet cars supercharger kit (1 Viewer)

[haedenlaird99]

I ended up ordering the supercharger kit from Australia. I really liked the turbo kit but i wanted the off idle power. Anyways It got delivered yesterday and now I’m wondering if I anyone knows if I can run the supercharger with no tune. It came with a xede processor with a base map and 2 extra injectors. The problem is I’m bad at wiring and this is my daily so I was hoping I could throw the supercharger on for the time being and either take it some where or do more research on wiring it up myself. The supercharger pulley is 7psi. I will have an afr gauge and boost gauge. I know the turbo kit runs 7 psi but the boost comes on differnt.

I would suggest reaching out to a tuner shop near your area and search other forums outside of MUD aswell for info pertaining to your SC. There might also be a dedicated forums out of AU.
Why didn't you order a Magnusson with US based support?

You should be fine on stock ECU at 7psi. Boost is boost. Before getting my turbo FZJ on a standalone ECU, I was seeing AFRs in the 10.5-11 range at 7psi and the stock fuel system. The stock fuel system is more than capable. The ignition timing is another story. However, I never experienced any ping or knock on the stock fuel system and stock ECU as well.

congrats! I'll be curious to see how this works out for you. The TRD supercharger is run w/o a tune and your unit seems to be about the same boost so logic tells me you should be able to run as is. After the additional doodads are wired up, and the piggy back installed, I'd then take the 80 to a tuner.

I went with the bullet kit because it was cheaper, the supercharger is bigger and it came with a water to air intercooler, extra injectors, piggyback ecu, and a higher flowing fuel pump.

The factory TRD supercharger does not require tune as also mentioned on post #43- your good!

Please update with pictures and how the install goes! What was your cost for the package plus shipping?

 

[haedenlaird99]

Here are some pictures of everything unpacked. It was 7800 to my door. But I had them send a high flow fuel pump, xede processor, and heat shield. So it could be cheaper without those. It got here less than a week after shipping which I thought was impressive. I still need to get an afr gauge and boost gauge. Also will need to delete the egr for fitting reasons. I got some pretty detailed instructions as well

This all may or may not be good information. Just a word of caution in regards to the factory ecu, there is a certain point in the TPS position/load/rpm that the the factory ecu swings from closed loop to open loop. Closed loop you won't have enough fuel, open loop is where you will drop to 10.5-12 AFR's. Depending how quickly this thing spools up and comes on boost you may run lean/have detonation. That's why our turbocharger is sized the way it is.

I hope that it comes in a little later and that you don't have those issues if you run it without the xede processor! It looks nice and I see it comes with a 7th injector. Does the xede processor just control the 7th to keep lean conditions from happening or did they supply 6 larger injectors + that seventh?

My plan is to monitor afr closely and if it needs the xede hooked up I’ll just take it easy until then. It actually came with 2 extra injectors both spray at the intercooler. I was told the xede processor controls the stock injectors and the extra ones along with timing. It is also and interceptor style processor

Does anyone know if you can just take the belt off an installed supercharger? If it will run normally? Just wondering if I do have issues with the tune maybe I can just pull the belt off until I get the xede installed.

 

[efjayatee]

I believe you can....

 

[60wag]

I doubt the compressor will let the intake air flow through it.

If there's a way to ensure the bypass valve is open, it'll be fine.

Yup, just got a response from bullet. They said to zip tie the bypass open and it’s good to go!

I will update you.....very soon

 

[haedenlaird99]

I’m in the process of installing this kit. I’m about to make a block off plate for the egr on the intake manifold but realized I need a boost source. Can I use that hole and make some kind of plate with a port on it? I assume I could since it would see manifold pressure. Also here are some pics

Recommend installing a EGT and coolant gauges. EGT changes fast if you are lean and you can melt the top of the pistons if not careful. Also, I found AFR of 11.8-12.0 keeps ~1400F EGT and watch the low-medium boost while on long easy grades that generates moderate boost for long periods of time and can kill your engine if you don’t have the correct AFR.

If AFR is under control it's very difficult to have high EGTs in a gasoline engine. You'd be much better off with AFR if it's one or the other.

Secondly I'd be looking for an AFR of 11-11.5:1 for a non factory boosted engine with boost.

Thirdly, to the OP, don't forget to go a heat range or two cooler in spark plug. Worked on a turbo FZ a while ago that would usually pull like a train but occasionally fall flat on its face under boost. Needed a good tune up as well so replaced spark plugs with what we would normally put in a turbo FZ, 2 heat range cooler copper NGK's and issue stopped. I can only deduce that it was detonating under boost when everything was warm and the knock sensors were pulling timing.
