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..

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 |

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......

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?

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 ![]() |

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 |

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.

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?

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 |

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.

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? |

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 Supercars “Z” datum; 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 |

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. Quote:

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.

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.
