Episode 30: Larry Perkins' 1993 Bathurst Winning Holden Engine on the Dyno 

1995!

And yet no media even gives it the time of day compared to the other races they wax lyrical about. That race is the pinnacle of flat out.

Great sound isn't it!

@@marcuswalker7398 sounds ace doesn’t it! Cheers

@perkinsengineering ....I am a bit of a tragic ....I have taken up listening to this on my phone ,loudly , while in que for coffee in the morning ...cheers me up ...makes my day

Gday Maf !!! Our Gemini engine was built to match the 92/93 engine spec with lower compression because of pump fuel and yes 355 and Harrop intake manifold carby engine made 500 hp 450 ft @7600 !!! 😜👍🇦🇺

The late Gregg hansford was the co driver in 93, russel come along in 95 🙂

@@gemini3558 You have a V8 in a gemini?

@@ausman05 yes mate road reg hot rod but we don’t drive it much, use it for drag racing !!! 😜👍🇦🇺

@@gemini3558 Always thought a Gemini with a V8 in it would be fun lol, any vids on here of it running?

Iron lion 💪

Cheers!

It does!!

Nothing wrong with that!!!

@@JoeC88 I think it's fair to say Brock was easily the best driver we ever saw in a Holden. He had a profound & well documented gift as a sympathetic, but brilliantly fast driver. Brock had Harry & Ian Tate & John Sheppard & others doing the engineering. Larry, on the other hand could drive too, maybe not quite as well as Brock, but Larry had the supreme engineering capabilities to build fast, durable & economical racecars. Larry was the allrounder who knew every nut, bolt & washer in the machinery HE built himself AND he knew how to drive that machinery all day, just fast enough to win, but not so fast that it broke. Luckily for us, Larry loved his Holdens, knew a Holden was better than a Chev or A Ford, (Remember... Larry worked with Johnson & codrove Johnson's Mustangs) he kept his faith, stuck to his guns, refined the Holden 5Litre engine himself & drove it away from allcomers at Bathurst in 1993, despite the big money opposition having imported expensive US crate motors. We owe plenty to Larry... He proved to the world for all time that our little homegrown V8 was more than capable of beating every other comparable smallblock this world could throw at him. Larry proved a point... On a level playing field, Australia's product was the superior product. Those who adore imported shit, bought imported shit & didn't support our local & better product. Local manufacturing died as a direct result. The dipshits who don't like Holdens are the very same dipshits who shit in their own nest & killed our superior car industry. I wouldn't own a Chev or a Ford because they only used caveman American designed V8s. We had the best little V8s in the world as was proven by Larry at Bathurst in 1993. Dummies still didn't catch on. Now all we have to choose from are junk imports.

Any mention of the aero changes that were once again aloud to be made to the Holden before sandown and bathurst in 1993 ? Has Larry still got them ?

@@johnbrooks9523 Damn right mate. I always admired LP's engineering & innovations.

@@JoeC88 Larry was treated like an outcast in Formula 1. After a dismal time in Europe he brought his supreme talent back home to Oz & got involved in Touring cars. He very nearly won Bathurst with the "Captain" Peter Janson before he signed on with Brock to replace Richards. Poor ol' Richo took the BMW money but found himself outgunned by the likes of the Brock/Perkins Marlboro HDT. Larry ran the HDT workshop & helped put Brock back into race winning cars. We were lucky Larry was shunned by Fomula Frisbee. His achievements here brought him instant national stardom & recognition & rewarded his talents where F1 left him broke & stranded. Larry has the runs on the board. His last to first effort in 1995 is the stuff of legends & will probably never, ever be repeated. But, in my view, his greatest achievements were engineering the Marlboro HOLDEN DEALER TEAM ONE TWO IN THE DAYGLOW ORANGE VK BIG BANGER GROUP C SEND OFF in 1984 & winning Bathurst with a HOLDEN ENGINE IN 1993 WHEN ALL THE SMARMY SPOILT BRATS HAD BIT THEIR MUMMIES FOR THE MONEY TO BUY IMPORTED CRATE RACE ENGINES! Larry is solid gold. A great achiever, who got the job done with the local product despite the fact, the rich bitches had more money & imported engines & every time some muppet tries to belittle Larry, I just laugh at them. I'd give anything to see Larry back on the circuit in any Historic Group C car. That would be a dream come true.

How good!!

That’s it, PE gear knobs were/are VW bump rubbers!

@@perkinsengineering awesome thank you for confirmation my Dad was quite proud that LP was a customer.

Haha yeah possibly! Although the current Supercar engines are a work of art!

Cheers Kevin

So it wasn’t just me?

You and me both!

Cheers Barry, i'll have to ask Larko about this video next time I see him!

@@perkinsengineering I am 110% CERTAIN he LOVED EVERY second of it! Larry Perkins is a LEGEND Jack at least as much so as PB, DJ, JR, All legends of the sport, LP not only drove he built the cars too!!!! Awesome!!

Yeah it's a shame we didn't have a reference engine on the same dyno as they all read much differently!

@@perkinsengineering Yes, that they do Impressive to see the 1993 Autronic SM2 with a firmware update, has hands free fuel mapping (Functionality perhaps not available in the current Supercar control ecu). Bosch 008 ignition module (factory part from a Holden JB Camira), OEM Bosch ignition coil. Simple, robust, technically excellent race wining performance.Autronic SM2 still available new from Autronic in 2022!.

Cheers!

That's it!!

Thanks! 😀

Cheers Malcolm!

Glad you enjoy it!

fiberglass

They are amazing, must save a few ounces over steel or aluminium and it's cool seeing the rockers moving.

Very thin fibreglass to save weight.

I think they are transparent so that you can check to see if there is a failure, I could well be wrong though.

@@vokstar it's simply how the fibreglass looks when manufactured with that particular cloth and resin.

Yes, yes and weight saving.

Same David. I can remember watching that 93 race and I was so proud that the Aussie 304 took it to the yank engines.

How good!

Cool isn't it!!

Was gonna ask the same question about the boots. They look like red backs to me. How do you like the steel blues? I’m wanting to get the best quality work boots Australia has to offer!

@Blvk Mvsk steel blue def most comfortable by far.

Sounds awesome doesn't it!

You're welcome!

1993 spec is same compression as today, 10:1. Heads are factory iron, then modified. And probably a big solid roller cam in it

Lots of special low volume bits in this engine. Larry went to the Holden engine foundry, massaged the sand castings to make only 100 cylinder heads and 50 blocks of which are much stronger than any standard units.

You need to watch the video with Larry explaining the slide manifold setup. The heads are also explained in that one. What a package he was as a brilliant Motorsport engineer and competitive driver.

You would have to ask him, in theory it's just above where the average gear change rev drop occurred.

We built it to 93 spec so it should be the same. We used 98 pump petrol and even had a period correct engine builder re-build it! If you implemented some of the "learnings" that are in the current supercar engines then it would easily find another 30-50 hp

Hahahahahaha very good!!!

He’s a legend and our first choice for engine builds today

Sounds good doesn't it !

@@perkinsengineering oh yeah you got that right mate

Stick it on another dyno and it might easily make that

Yes Bill was a great customer for many years

Cheers!

Hahaha needed the commentary!!!

Crazy to think someone would dis like it, but there's currently 2 people!!!

@@perkinsengineering probably 2 of the blokes who finished behind LP in the 93 race!

Yes sir, factory Holden firing order

That’s why the Holden V8 sounds so good. Jeff

Gotta love the sound of 1 2 7 8 4 5 6 3

Thanks Grahame

Cheers

Sounds good doesn't it!

Absolutely, built as per period specs too, if we could implement some learnings with current engines it would come very close to what you will see in a Holden Commodore ZB this weekend in Perth!!

@@perkinsengineering do you have another block jack? Could get the Larry to build something g new for us fans

Cheers Craig!

It’s not free reving , the Dyno puts resistance on the engine to measure the HP and torque output

C Reid is correct.

@@CMReid Normally a water resistance torque converter style,right?

@@SuperTambo69 yes mate that is the most common one

So do we!!!

He's a ripper fella!!!!!

It's a dyno room/working space, not a museum!!!

Cheers Craig!!!

Doesn't she!

Yeah it's hard to do that stuff without an engine in bits....

Not wrong!!

Yeah it sounds good. So it's about 60hp less than what a Walkinshaw Engine running around in Perth this weekend will have. Can only compare Engines on the same dyno, or accept a possible 7-10% offset adjustment!

Nothing wrong with the belt 😉

In the camera that's mounted above the engine, there's no muffler to what you can hear from the valve train at all because the rocker covers are so thin. Put a bonnet over it and you won't hear any of it
