Nice kits and all but the mechanical fuel pumps is something I still just don't agree with for anything even partially road car. Much weight, complexity, failure points, illegality and other problems compared to a single intank pump. And if 2000+hp vipers & GTRs can run a single intank pump then I'm not sure why there's the need to go mechanical for anything less. Brushless intank pumps are a wonderful thing. And paired with properly designed syphons etc no need to worry about G forces.
@Stefan Prijic some pumps are flowing over 1000lph at 6 bar with around 30A. Others flow over 1100lph at 8 bar but are then drawing 52A. So comparable to what a lot of people have in terms of lift and multi pump setup (Walbro 525lph @3bar from Hellcat is up to 25A I believe) except in 1 more simple package. Less fuel heating. Less failure points. PWM controlled. No need for big mechanical fuel pump regulators etc.
@Scott Hobday not saying there isn't necessarily a reason to run these especially again if it isn't a road car and a bunch of the issues mentioned become moot or you're running methanol etc. But there are alternatives and sometimes...actually with a lot of these cars it's just because a product is there and pushed so lots of people who would be better off with another solution end up buying it. For sure there are some that have a definite need for these mechanical pump system. But I will bet the % that need the mechanical over a good brushless is very small.
The best place for the mechanical fuel pump is on the drivers side wheel. The faster u go the more fuel it pumps. Can keep an eye on it in the revision mirror too 👌

May i ask why didn't you just put on a carburetor low pressure regulator on overflow in the sure tank in the back ? Matt Field runs this kind of setup in his fd corvette making north of 1500 hp
@@sexyfacenation it keeps the surge tank and the line from tank to pump under pressure. Doing it that way prevents fuel surges caused by front mounted mechanical fuel pump. AKA solves the issue without reengineering whole fuel system.
Very nice car and makes some awesome but at what point does it become a nice street car to being a defect magnet for the cops and having the car taken off the road ?
This is not a matter of getting enough fuel as the car is sitting there (on a Dyno, for example) but it's the effects of the G forces under hard acceleration that slow the fuel supply to the front of the car. Even a larger line could still have the same issue. This way is foolproof because you constantly have a reserve or fuel less than a metre away from the rail
-10AN is too small for the suction side for that long of a run. Needs to be -12…..Obviously the surge tank up front takes care of that issue also. That front cell should have a cage around it. Wouldn’t pass tech in the US
Andrew do you think you will return to doing platinum tech videos? If so would you consider doing a cylinder head comparison? Rb26, r32 rb25de, rb25de r33 rb25det, rb25de neo rb25det neo. I'd be real interested to see the differences in standard form.

That's strange, I run a fuel cell at the back and never had a fuel pressure issue, it's rock solid when you look at the logs

A small front section crash even with low km can make instant the car fireball! This is no street car anymore!
I cannot believe how obvious this is and how it's not been mentioned
I’m very concerned about this as well.
That is a vulnerable corner on any car, did they use fuel tank foam and do you have any concerns or taking any mitigation increase of a bump?
Exactly what I thought... but if you want to increase the risk of a fire or an explosion in an accident its a pretty good option.

Of course its not ideal. Not to mention on a car like this, its pretty far down from things that are theoretically illegal for the road.

What's the current draw like on a 2000hp capable brushless pump?
Agreed. This is just an unnecessary risk when huge brushless Pumps are available. 15l in an aluminium box in crash zone?? Nah.

If all of the big GTR’s are running them they must be doing it for a reason.

What do you use as a primer pump for the initial start up? Just the pump is in the frenchy hanger enough to pressurise the system??

Why not just use a high flow electric fuel pump from the surge tank in the back to help feed the mechanical one?
Mechanical doesn’t fail or effected by alternator/battery and draws no current

In Australia cops will defect a stock car. We havent pulled over and defected in it in 11 years

Let people do what they want. Tommy has his thing and other people doing it differently doesn't mean its wrong.

Usually the same as the outside but darker and full of fuel. What are you wanting to know about the inside?
