Nissans new v8 supercar motor wtf.

[ebxr8240]

I would say the 4 valve may loose some low rpm torque compared to
2 valve engines ??? The rev limit is low for race pentroof head engines..

I would say something like this, the 4v head is going to have massive combustion area and prob a shorter crank to compensate for bigger daimeter pistons?(meaning they may rev faster?).

Its a totally diferent motor so why do ford and holdens still need the same stone bro's units ect.

Or is that set to change?

4" bore and 3" stroke makes a revy engine.. As in Ford engines..
The 2 valve heads are a well designed piece of gear ..

[XARATE]

Theres a simple reason that ford wont ever use the coyote for the V8SC.
Rules dictate that for an engine to be used the MINIMUM bore size is 101.473mm. The 5.0 coyote is 92.2mm. Way short of the rules

They don't have to, and come 2014 i don't think you will see to many (if any)
of the current engines in use. I think you will find 2013 will be a transitional year.....

Have a look around The Pits, all this and more has already been discussed in numerous threads with plenty of linked info......

[tapeworm]

Each team should have a certain limit of how much they can spend on a v8engine and maybe a limit on capacity and be able to go nuts on it. Then you would have all sorts of variations on race day. This would make it interesting and no one can complain if they get murdered on by another team as they all have the same budget to work with....no?

[Chrisosicko]

Can't wait for the added competition ford vs holden is getting a bit old and boring now

Hope you have thick skin

Because its coming

For the record I agree with you

[Sprint]

I would support nissan for a change if not for kellys team.

Mainly because lownsie and whats his face has brought ford fanning into destripute with me lol.

Frosty and moffat are still legends though.

Are we going to be running pushrod old engines against that?, iam a bit confussed as i thought they all neeeded to run a generic engine.

I love nissan as i own a skyline but i cant see ford making a new motor like this?

http://www.caradvice.com.au/189282/n...to-fuel-sales/

They can make as much HP as they want, and be as fast as they want, but if they are too fast they will be pinged and brought back to the field.

They will learn fast, be up to speed, run mid field by sandbagging and they will do a full brutal attack at Bathurst next year and smash everybody else out of the field

Thats the plan anyway

Its just like GTR days over again

Yeap, and when used in the production Holden SS and HSV are THE BEST production V8 engine for sale today, bar none.

No need for complex DOHC and 4V heads, they are good for marketing i suppose

[prasac]

they do use the modulars, VK engines and they are proven in GT1/GT3 racing but they are also only 1 hour long races etc, running 1-2 hours a race weekend and running 5-7 hours is a different thing. do i think they can do it, yes i do.

i been saying for years they should allow DOHC engines into NASCAR, V8 Supercars etc. now is the time

[CAT600]

Paulie dont forget the Rolex 24hr... uses all the 32V Grand-Am engines we are talking about here.... Ford's Rolex entry is the same as GT3 in terms of power and they came 1-2-3 at the 24hr at the start of the year

Who says Coyote cant make it?

Daniel

[tweeked]

Production based engines (destroked LS2 and a Coyote) in the COTF an I would be interested in the V8's again. It would have just enough relevance to getme back.

[MAFIA]

If the old pushrod engine meets the 5.0L cams required! Then why isn't ford using the lastest and greatest Quad cam Coyote 5.0L V8 in the supercars?

Does anybody actually read anything i write?

[CAT600]

So they have to stick to the rules forever?

Grand am engines run bore sizes from 92mm to 102mm... They have excellent (albeit far more relaxed and diverse) parity requirements that work out in the end. This along with GT1/3 racing is way more exciting than current V8SC IMO.

Daniel

[T3ts50]

I wonder what the chances of the Holden teams running a de-stroked version of the new GM 5.5l thats being raced in the new Vettes.

[CAT600]

Also, can anyone confirm that the Nissan engine is a 101.2mm bore, because factory they are only 98 and the article expressly says the capacity reduction is by way of bore.... No mention of a destroke anywhere.

So 92x92.... Hmmm sounds familiar?

That rule still current with COTF? from reading the specs it seemed less strict with engine requirements.

I'm sure i have read somewhere that Ford teams are looking into the viability of a Coyote "based" engine, never say never.

[XARATE]

I just read it from 2012 devision C 1st update rules

C7.3 Cylinder Block
The following conditions apply to the approved cylinder block:
7.3.1 The bore size must be 101.473mm or greater;
7.3.2 The fitment of sleeves to the cylinders is permitted;
7.3.3 The nominal section of each cylinder must be circular;
7.3.4 The location of the cylinder block within the body shell, as measured from the front
edge of the oil pan mounting flange must be as stated in the relevant VSD
7.3.5 The axis of the crankshaft (the pitch angle of the engine) must be a minimum of 2 degrees and a maximum of 4 degrees downwards to the rear with respect to the V8

7.3.6 The engine mounts are free but not their number nor position.
7.3.6.1 It is permitted on the Ford cylinder block to utilise additional engine block mounting points. The additional engine block mounting points must be placed in the pan rail and must not be located past the 2nd and 3rd main bearing journals on either side of the cylinder block.
7.3.6.2 It is permitted to mount the engine by the sump to the front suspension cross member complying with Schedule C 10. All designs of this type are required to be submitted to the CTM prior to being implemented by a Team.
7.3.6.3 No other component or accessory is permitted to locate or mount the engine to the chassis.
7.3.7 The cylinder head face must remain at 90°to the cylinder bore centreline.
7.3.8 It is permitted to add or remove material to or from the cylinder block, subject to:
7.3.8.1 the integrity of the original casting of the cylinder block being respected; and
7.3.8.2 that no attempt is made to vary the basic design of the cylinder block beyond modifications permitted in these Rules; and
7.3.9 It must always be possible for the cylinder block to be identified as the approved cylinder block.
7.3.10 The minimum deck height of all Ford and Holden Motorsport Cylinder blocks is 207.0mm. It is permitted to use components that do not comply with this dimension
during Rides and Testing only.
7.3.11 The camshaft lifter bores must remain in the same location as specified by the
manufacturer and the samples held by V8 Supercars on the Ford M 6010 Boss 302
and the Holden Motor Sport 22534350 cylinder blocks.
7.3.12 Cylinder Block Weight
7.3.12.1 The Minimum weight of any cylinder block used in the VCS will be 70 kg. The weight of the block will include any Core/oil gallery and Rear Cam tunnel plugs Cam Bearings and any internal oil feed or scavenge lines and removable rear main seal carrier.

Unless V8SC relax or change the rules ford and holden are stuck with what they have

[melon466]

Exactly, the rules are made around the category, not to its detriment. If things start going pear shaped with Nissan dominating again due to technology, the rules will be relaxed.

My thoughts anyway.

But isn't that the current ruleing, not the COTF ruleing, yeah?


Mark Skaife has already welcomed the idea of Ford and holden using different engines.

“If Holden or Ford come to us tomorrow and say to us and say ‘we’ve got a different engine that we’d like to make into our future engine’, then we’d be up for that, no problem at all,”

Speedcafe


Same artical also has this jem...

The Coyote engine that is currently in the FPV range is a fantastic little V8, and has all the hallmarks of being a good race engine. I’d love to put one of them in our cars,” Little told Speedcafe.com.

The bottom end isn’t that much different than the ‘Cammer’ engine that’s raced in FIA GT1 and Grand Am, which you can buy direct from Roush Yates for less than what our current engines cost us.

[FPV GTHO]

They'd be better off just going for the Cammer anyway. I keep saying it. Its still a 5L like both the old and new engines and the majority will see its DOHC and either think its the new one, or accept its a step forward regardless.

no, holden and ford updated their engines a few years back with Project Blueprint. they are not like the old pushrod dinosaurs like nascar persists with.

[FPV GTHO]

I don't really see what makes a NASCAR engine a dinosaur and a V8 Supercar engine not. The only big difference they ever had was the fuel system, and now NASCAR are going fuel injection.

They still run pushrods

Engines pinned at 9000rpm for 500 laps...not really dinosaur eh...quite amazing.
