The amount of knowledge Tuning Fork has is just staggering. He could *literally* write a book!!!

[@MrThebrownie72]

Completely agree mate and really wish he would ,would be a fantastic read just in itself let alone as a guide

Scotty is such a wealth of knowledge, i love listening to this guy talk about fuel maps, injectors, fuel pumps, etc. I've learned so much just watching what he does through MCM, this channel and random other appearances.

It’s amazing to think this car started out with a sponsorship with transformers.

[@Jim_M_75]

Very special car for many of us, we watched it made and Benny took it on and turned it into a monster. 1500 whp at some point for sure, the best thing about the car is it puts the power down so well and runs great times without any effort, the chassis seems so well suited to massive power the way it was built.

[@fitzeesfabrications]

I do love Scotty's attitude, & humour whilst beating on other people's stuff.

[@Machine_s15]

If you are running the old style walbro 460 (F90000267) they start bleeding off pressure at 85psi. I found out the hard way. Basically if you have a base fuel pressure of say 50psi, as soon as u get near 30-35psi of manifold boost pressure you will start running out of flow pretty quickly.

[@bigunone]

[@if66was99]

Very cool t-shirt Benny! Twin turbo Chevelle.

[@jord9308]

Fuel flow will be restricted at the smallest point in the system, usually at the junctions. Holley makes some larger connectors with larger internal diameters. Flow is inversely related to the 4th power of the radius. So increasing pressure only helps so much.

[@BennysCustomWorks]

jord9308 the supply is -10 to twin -8 and all are full flow fittings. The plumbing isn’t the issue. A dead or dying pump is.

You mentioned not being able to fit a mechanical pump. What about a cable driven pump? That way it can be remote mounted

[@aSinisterKiid]

It's a good day when Scotty's in the driver seat.

[@gavinb9627]

Great video as usual. While the end result wasn't what you wanted, the diagnostics I think was a huge save. The nice oily bits stayed inside the block, you again ran a PB and you didn't waste thousands on the new build. Now to build a new stronger fuel system, if all the voltages check out

[@glensgraphix]

Great video. Good to hear all the technicalities being discussed and nutted out instead of them being edited out and a short explanation at the end.

[@BFE08STI]

You can get external mechanical pumps with a flexi drive thing. Cleetus has one on Leroy if I recall correctly

[@BennysCustomWorks]

BFE 08 WRXSTI the pump size isn’t the issue, we can’t physically get a drive off the end of the crank as theres only 20mm from the end of the damper to the radiator .

[@BFE08STI]

@@BennysCustomWorks Ah, I see. Just wanted to throw the option out there if the placement of the pump around the engine was the problem

[@davidjohnson8474]

Benny's custom works something you might look into is here in the states in nascar cup series they use efi but use cable driven fuel pumps. They run 8 to 9500 rpm for hours and the volume and pressure stay. They used electric pumps in the beginning but wouldn't last. It might be a solution for you.

[@BennysCustomWorks]

David Johnson no room to get drive from the crank unfortunately otherwise we would 100%

[@davidjohnson8474]

Well I've seen 2 ways like one driven off the flywheel and from the back of a dry sump which I don't think you have. Also a little pulley off the front of the engine driven by a belt.

[@jasonworks1362]

So what's this mean ? new fuel pumps and then you have to make 7 Sec cresta shirts for drag week 2020 ?

[@ArKritz84]

Probably, but they haven't nailed the problem down to the pumps specifically. Wiring, lines, filters, rails, injectors, everything has to be correctly sized and working perfectly.

[@jasonworks1362]

@@ArKritz84 i personally think that the biggest challenge would be if the car goes faster than 8:50's then it will need a different cage

[@whitey1195]

Also incredible that this makes more power than a Bugatti veyron with 10 less cylinders, a quarter of the capacity and 3 less turbos.

[@catfish552]

Barra magic!

[@Karjis]

Half the capacity, Veyron engine has 7,993 litres capacity. Anyway probably veyron engine has better driveability as it is quite mildly tuned engine (125hp / litre ).

[@Arturro671]

Scotty - ,,it just works" - are you a gamer or something? :D ( 10:44 )

[@SB-vb8ch]

If you're not running a referenced fuel pressure reg & a fairly low static line pressure with big boost then surely the biggest factor is the fact that the pressure difference across the injector drops to almost nothing. Fuel won't flow if the pressure difference is low.... first port of call would be either crank base fuel pressure so you maintain a big enough pressure drop across the injector at higher boost or go to a manifold referenced fuel pressure reg which would give you the same effect. You guys have seen more & probably forgotten more than most people would ever know but this seems an odd conclusion to me!

[@BennysCustomWorks]

we are running a vac referenced reg.

[@tonyanderson4774]

Benny, give Pat at Competition Systems a call in regard to alcohol fuel pressures. Not taking away from tuning fork at all, cause he is a jet and I know you hate reading the comments section but seriously, give Pat a call. He has a wealth of knowledge on efi alky fuel pressures.

[@kolelambert41]

What reg are you running?? Is there only a pressure problem at higher boost levels??

[@BennysCustomWorks]

kole lambert we always use gfb regs. The reg isn’t the issue , running out of pumps is our issue :) we’re already in the case.

That sucks man. Are the pumps still the same ones that were put in when the car was first built??
