Re: Building the supercharger to the engine (75 3.0V6)

timing light was broken. It was a brand new one.
Bought an other one without rpm calculation and without a timnig you can set on the timing light because i heard a lot of bad stories from them when i searched the web.

Finaly we can drive again! :)

Re: Building the supercharger to the engine (75 3.0V6)

Had a nice vacation in France for a coulple of weeks. Thanks for the thinking guys. A new ecu would be very nice. It also is a lot of work. I have to learn myself all the new software. Rewire the engine becuase it is set for batch injector fire. Install a camshaft angle sensor. I orderd a new timing...

Re: Building the supercharger to the engine (75 3.0V6)

Yes, thought of it. But let's first see if it is something more cost friendly.

Re: Building the supercharger to the engine (75 3.0V6)

Is it possible that you may have a loose front pulley? Checked the nut. But it was tight. @MD: your far of. It's an interstellar problem :wall: No offence mate :wink: With the new brace it looks a lot better then before. Now it is only a few degrees. Orderd a new sensor because it once rubbed the t...

Re: Building the supercharger to the engine (75 3.0V6)

Because of some strange timing issues i made a new bracket for the crank sensor. Timing was jumping +/- 20 deg.... hope it helps. Never had the problem before. Maybe the slight new position after engine rebuilt causes this. I dont now. The old bracket had some flex in it. Harness seems to be ok. htt...

Re: Building the supercharger to the engine (75 3.0V6)

Thought of an electric wp but i'll hope the smaller pully and the new position af the waterinercooler radiator will do the trick. I once had a snapped belt and that is why i connected a buzzer to the arc. When the car doen't charge the battery the buzzer alarms. So when the belt snaps the alternater...

Re: Building the supercharger to the engine (75 3.0V6)

almost ready to get MOT. Did some testing miles on the road. Looks all good. Post you the last updates: smaller water pump pulley for cooler idle temps at hot weather. Full load never is a problem. I see around 82 degrees celcius then. https://myalbum.com/photo/kWc9GV7esKwN/540.jpg Reduced unusefull...

Re: Building the supercharger to the engine (75 3.0V6)

No sequential injection for me...

I'm reducing the volume now after the throttle body wich helps and with a supercharger application where the throttle body is placed in front of the charger, the volume is big.

Re: Building the supercharger to the engine (75 3.0V6)

That is approx 330-350 crank hp from a 2.78 ltr engine.
Think I first go the dyno with the cams backups 6 degrees and a normal cam setting just for testing and see what the difference is.
