Thanks for the update great to hear another engine option out there. Chassis looks a little like the classic kurigers that were awesome with the old ford truck motor, and it seems to hook up on the poleline like nothing else. Well done to the team, cars and driver seem to be going from strength to strength

Also wondering what sort of revs this beast pulls? Screams alright and reminds me of the Nelson Midwest 6 motors tha used to have 6 pipes pouring out the sides

Thanks! Pm sent!
Had the same (almost, 7100 and 7400) in my Chs Holden.
It screams alright, wondered what it got up too. Lot of revs for a ford 6, I wonder what a reliable ceiling is?
Clearly reliable now, and has plenty of pace - thanks for sharing the videos, car really puts power down and seems to stay nice and tight

I've heard there is a crowd in oz that can build one within the rules with more than comparitive hp figures and a nutse load of tourque for around 9 grand delivered.
That would be i impressive if true, and makes sense seeing as the falcon is oz made! Lol

Atomic performance.
They reckon they can squeeze 1800hp with a turbo engine and still have it street-able. I emailed them once about what a n/a motor could get up to and they were confident on over 500hp with their special billet parts... Thats actually not too hard to believe - the ex 55h cortina of Lance Slater had 450hp on a dyno - thats an au based engine with a seriously worked ea head and over 12:1 compression...

Makes ya wonder why people spend moon beams on v8s chasing power, when being on dirt ya want the most torque and for that I'd be going VH41 or falcon 6.
Such a smooth torque curve with a 6 too.

peer pressure - look at Adam Groome if you want to proof. He had nz's fastest 6 pack built out of an ea of all things. spent a few grand each year and got good power, left alot of v8s in his dust but still changed to a super expensive v8... why?
Well in his words "I got sick of being laughed at for only having a six cylinder and kept being told if I wanted to win races i needed a big power v8".... that was after several years of consistent at the top of the pack running and heaps of race wins with a six pack.
Theres an old saying - the drivers make motor-sport, usually they make it expensive.

Steady on lads. There's still a way to go before the 6 takes off.
22b has done very well with a couple of results in races, but when you read the posts above he is the first to acknowledge the correct track conditions etc are required to give the car it's best chance.
You watch the in car footage and the v8s still drive very hard off the turn, and have a lot of pull at the end of the straight with those big revs.
Does appear to be potential for more power and revs from these motors so will be interesting to see if they start to gain some favour.
As a side note that 6p historic of dAVE evens that was so good has the Clifford ford 6 truck motor has 12:1 comp wow

The only way a naturally aspirated engine can make power is to rev, the v8s have had all the research done to make them do just that and still be legal - so far the six cylinders havent had that research done. yeah they can rev up to 7 grand happily but theres alot more power waiting to be found in there. |

You've done some research rhody - nice link to atomic - has anyone talked of getting some solid revs out of these motors? The turbos seem to have the boost and airflow but that's no help. Is anyone taking these motors out to 8 reliably?
Surely there's some you tube footage of numbers being pulled, but I guess the n/a option is quite rate given the turbo has value.

this is what Atomic told me when i said 89000rpm on a carby.
Hi,
If you want to get to 8000 you will need to change the conrods, the pistons, the oil pump gears, the head bolts, the cams, the valvesprings and you will need good porting as well.
You will get to about 6500 before the conrods and pistons fly to bits......
You also need a set of our Vernier cam sprockets if your ECU can’t control the factory VCT solenoids.
If you have any further questions, please dont hesitate to call/email.
Cheers, Brad

and thats pretty much what they told me too Chicane, its worth noting that when porting you port both inlet and exhaust, but only polish exhaust to get better exit flow - you need the roughness in an inlet port to help atomize fuel.
Vct is illegal in the class anyway so that may as well come out, you can save weight and rotating mass with the lighter sprocket system - less rotating mass = quicker revving.
Standard head bolts stretch and let the head lift at 8000rpm - just ask Sandy898 - a good set of arp bolts should fix that, you can happily rev all day at 6500/7000rpm.

6000 came quick in the road car in both 1st and second, at which point it started holding back.,,,,but it was third that was the smile maker, pity had to sell that car...looking at buying a motor just to have one round the place

Would that be legal in a super saloon?

Would be excited about superstock options.
I guess depends on how much you'd loose trying to get it too those specs
Think it runs on methanol, and clearly needs a carb. And who knows what comp.
But man, awesome to see 500 dynoed hp with an n/a BA Falcon 6
