Does this bolt into the factory position?

Why the low boost? What do you intend to turn it up to?

I don't think the powerband in a turbo petrol is small enough to warrant this setup. How about just hooking up an 8 speed Auto.

You cannot base everything on the fact that CAT use this system in large dump trucks where weight and cost are of little issue. The systems i have been talking about are also made by CAT...does that mean they are superior....NO. The 20-30% efficiency may come from regenerative braking where energy is stored while travelling down the pit and then used later on

Is it more efficient weight wise?, power wise? cost wise? simplicity wise?

Engine produces 150kw @ 3000rpm 180kw @ 4000rpm 200kw @ 5000rpm. 170kw @ 6000rpm You need to access that 200kw so the throttle is open 100%. It cant go over 5000rpm because the engine makes less power above 5000rpm. You can vary rpm using the throttle to achieve what you want or you can vary load on the engine using the variable hydraulics. It would be a combination of both

Variable speed hydraulic drives do EXACTLY this. We use them at work on our pit pumps. The diesel engines are set at their most efficient or max power rpm and then we just adjust the flow according. You don't control the load.....you just control the rpm using a governor or in this case your right foot.

This would probably be easier using a good variable speed drive Hydraulic setup.

I think it was explained before with a current and valid example that it would not cause too much load on the alternator. If the alternator was rated at 600 amps then yes it would take all the power purely from alternator and thus put quite a load on the engine. 600 Amps for a short period from a decent battery is not hard at all. Think of it as pulling stored energy from a battery and then being trickle charged from the alternator. If the electric motor is in open circuit then there would be no current draw and no extra load (besides what it needed to spin it in the first place). Do you think your alternator puts out full amps all the time while driving? I'm not saying this will work but its definitely not unachievable. A couple of brushless motors that are directly on the shaft could work. I don't see why it should be disengaged at all.....surely the spooling from the motors would negate the added weight.

Diesel locomotive does exactly this but not sure why this is in Forced induction.

The current will be provided by the battery and the the alternator can recharge the battery as needed. Plus the battery will prob not accept the 60 or so amps available by the alternator. This is exactly what happens with an electric winch on a 4wd. The winch on my patrol draw around 600+ amps and does so for 3-4 minutes before i give it a 5 min rest and the go again. The alternator does bugger all during that time as it can only supply 40-50 amps to the winch. I also only use one battery in the patrol and have a battery in the boot of the r33 that is big enough to do the same.

I have coils for a S2 R33 if that helps. Pm if interested

E85 is 5 mins from my house and i still found the range anoying for a daily driver!

I tried 1mm and it started to miss so backed it down to 0.8mm and so far it's great. Hopefully it stays like that when i wind up the boost!!

After having misfire issues i hunted around for a new set of coils. I found a brand new set of genuine Nissan coils for cheap. How much plug gap should i be able to run? Currently making around 240rwkw at 15psi or so Cheers James

How does Nistune compare with a Dr Drift style tune where a daughter board is installed for an R33? I have been using one of these for the last 3-4 years with no dramas. The only problem so far is finding someone else to tune it. Nothing wrong with Dr Drift tune but he is often booked out for weeks Jimmy

Electric turbo?

^^^^^Beat me to it

Was runing around 18 psi on E85 with yellow jackets (255rwkw). Changed back to 98 and 15psi and have had to gap down back to 0.6mm due to a miss Grrrr Have also had 2 fail but replaced under warranty. Anyone running higher than 250rwkw with YJ?

Hey mate how much to post the coils and loom to Melbourne? How old is the loom? Jimmy

Just filled up. Took 50L and drove 350km. 14L/100km of hard driving is excellent!

Just switched back to 98 after 18 months or so on E85. (Around 240rwkw) So far on the first tank i'm up to 320km and about 1/8 of a tank left. There has been very little cruise going on. I would say 80% of the driving has been foot to the floor (very little O2 use). Very surprised at the economy. I would love to take it for a long country drive to see what is possible but it's too much fun on boost Jimmy
