Someone once told me Ultima insurance was cheap. When asked why he said because you either respect them and don't crash or you're not able to claim from a box.

When you are buliding ultimate race car like FXX, Zonda R, you dont watch about money. But if you are building cars like British Ariel Atom, Caterham, Westfield, Radical etc. and Ultima GTR, Shelby Cobra... you are usually limited by budget. Light cars can use smaller engines instead SBC. Ultima GTR with LS7 and G50 transaxle is perfect for track days. And price same as standard ZO6, makes Ultima much faster and fun to drive. Sometimes engineer need find balance.

Ford DOHC design sucks in weight, but it's reliable. Well SBC are good if carrying all modern stuff like LS7/LS9. Engine weight can compensated by reducing weight of car. Example is McLaren F1 which weights 1100kg, but S70/2 BMW V12 engine weights alone 265kg or 585Ibs. Same thing is with AMG V12 in CLK GTR and Zonda's, specially in Zonda R, where weights 235kg or 517Ibs what is excelent for V12. For example LS9 is 540Ibs fully dressed.

@2jzgtejza80 The only issues there are the weight being much higher up in the engine - in an Ultima that would be a killer for CofG, lack of power and a big lack of torque from most and in all cases cost. If you use the money left over from buying the engines to build an SBC you will get a LOT more power for the same money.

You also have to include all the other bits for the tech like ecu, intercoolers, etc - it all adds weight the SBC doesn't need. Tech sometimes wins.

@hunghuge12

Modern BMW engines are one of the lightest engines on market you can get. New straight-6 twintubo, weights 340Ibs including all parts installed on. Engine block is made from die cast magnesium-aluminum alloy. 30% lighter than standard al-alloy block. Older S65 V8 from M3 weights 440Ibs fully dressed. Only engine builder comparable with DOHC design is AMG. AMG engine in SLS 6.2 V8 weights 470Ibs, same like LS7. Technology always win.

@hunghuge12

With T56, LS3 going up to 28mpg instant easily at 55-60mph in C6.

[hunghuge12]

@skylinegtsrock Doesn't the same go for any car though?

[hunghuge12]

@DrBoyton Or 479hp and only 150(ish)kg of engine. Ignore power to cc and look at power and torque to weight.

[hunghuge12]

@folerx Driving like that I would say between 10 and 15mpg.

[hunghuge12]

@2jzgtejza80 You wont get 30mpg because of the gearing. 15-20 if you're really light on it. or 4 if you aren't.

@orkust same with all kit cars really if youve built it your not gonna wonna crash it and if you do crash it youll be able to repare it, insurance premiums are based on the number of claims ect
