Holden 5L V8 | Harrop Low Profile Supercharger Preview

This is excellent, very well done, awesome design. I first saw these chargers on The Skid Factory's channel. Don't worry about the negative comments, some people don't appreciate Aussie made and want boring Canadian/Mexican made LS, the rest can't afford real power upgrades for their ragged out VN SS lol. Can I ask, does this also fit under a stock VT 5L bonnet? Cheers!

Iva got a 12 second quarter mile daily driver VL Calais with built VT roller cam 5.0 stroked to a 355 with forged 20 cc dished pistons dynoed at 310 rwhp on carby back yeard tune, was Originally built for a procharger but never happened, I'm keen on one of these now I wonder what power figures it would run ? also what boost can this pump like 25 pounds ?

The holden motor now makes the same power as a stock LS.

is this a joke?

The Holden 5l belongs at the bottom of the ocean, a complete waste of minerals from the earth

All that cash to make 15% less power than a stock LS1

anyone with a vz ss with a harrop 2300 what the fuel consumption like on the highway doing 100 110 and what power you making aswell as cost

😂 my n/a 5litre makes more

Would this work on VK carby 5L?

Look at the price,you must be joking.

Definitely not better than an ls conversion 😁

If that motor is stock in that car I doubt if it would have a roller cam etc.225rwkw is 30+rwkw more than a stock 6.0Ls. My low km 6.0Ls dynoed 180kw at wheels stock. A chip and pipes gets you to 230rwkw. Most bang out of a stock 6.0Ls is about 260rwkw. A Ls will cost you like 50k now before installation. So 9k for something that goes that well and sounds as tough is cheap. the modified VT roller 355 version does 600kw

What did tis set up cost

Love my harrop htv 2300 had it on my vz clubby for 6 month and only done 1300km in it..and its already making loud grinding and rattling sounds from it... amazing product i really hope you fix it under warranty

My stock 185kw motor running 1.6l auto rotor/whipple with cutdown banana manifold with top mount 4barrel throttle body with bigger injectors headers and exhaust running 5.7psi made 255whp an 650nm@2200rpm non intercooled. Loved 12psi tho not sure what hp was at that though

And I’m sure it cost $12,000

Are you seeing very good IAT by using the larger blower and lower boost levels?

Just don't take it to gentech.
Marcus sux.

I Wouldnt thought there was enough of them boat anchers around to be worth R AND D,had a couple in the day,why dont you a setup for 351 cleveland

only 22 years late good work

Hey guys who love these vr vs utes with 5.0 engine ,, I know of one that will be up for sale ,,, this is a white 94 VR 5.0 S pack manual transmission with just 65,000 kmh or less and is still in original un marked paint , all books n papers , this car is best described as almost new still inside and out , has had simmons wheels from day one , have to be of the lowest km in this shape left

Makes less power then a tuned ls1 🤷‍♂️

Pair it with an interchiller and let her eat!!

90 more HP for a what?, $16K investment and questionable stock internals. No thanks.

Poor value for money ,,, LS or turbo much better imo

Killer Street car

Did the super charger come with a free box of tampons?

Don’t forget the 50% increase in torque it’s making. This would be a nice engine on the street.

My vs 5l made 296hp 389lb.ft with a just a cam upgrade

Yet another necessity I cant afford...

Non intercooled? Wont that cause heating/performance issues instantly?

Tell Joel to wind that shit up, until it throws a rod or two, then back it off half a turn.
If I was going to spend Harrop blower money on a 5.0, surely, I'd have the coin, for some supporting mods to the long block.
A whopping 7psi, please, I piss with more pressure.

Lol...Ls makes 100 more hp with just tune.

If it doesn't pull 400+rwhp chuck it in the bin boys...although I wouldn't expect miracles without an intercooler so I'm gonna guess this perticular setup doesn't even make 10psi...

I’d put the money towards a fresh LS conversion if it was me….but each to their own.

all that for 89hp? Pass!

Yeah Nah

People having a cry about the dyno figure 😂 thinking bolting a charger to an otherwise stock 5L with no supporting mods was gna make 500hp

KW & Nm?

The most expensive 90hp you will ever buy

This definitely beats the old days of centrifugal blowers hanging off the side

Yes !!!!

Would be nice to have one for the 5 litre Windsor too 👍

The thing most of you nay sayers are missing is that its non intercooled.
Theres massive amounts of power left to be had here.
There just isnt enough bonnet clearance for the intercooler brick thats usually under the supercharger.
40% power increase is savage non the less.
Can it be done cheaper? Yea it can.
But will you have the appeal of owning a roots style supercharger? No, you wont.
This is a prototype not a finished product.
That pully is absolutely bloody massive whats it making harrop? 4-5 psi?

I would say to keep the donk way better for power gains than an ls conversion 🤙🏻

What software are you using?

Animal. 👌🏼

Only suits VP-VS ? Why no VN ?

11 grand to make 89hp good power adder but cost effective i don't think so 🤔

Can the intercooler be retrofitted at a later stage?

Very nice 👌
