[MrTopanga44]

this is a genuine round tube 1964 G4

[080969msryan]

this little car has to put a silly ass grin all across your face.

@MrGospelMan

the g4s of the sixties were almost fully built by the factory, with just engine and box to drop in, to get around tax problems, so they are not true 'kits'

this car has Lotus Twin Cam engine around 190+ BHP..... that makes the power to weight of 400+ needed to beat the american muscle.

@MrGospelMan I know about the 7 stuff and how many manufacturers make them. The G4 is not of the same vein. We'll go to private messages now.

Hey, I'm not trying to start an argument on youtube comments, I'm just saying they have a kit heritage.

Google it. Lotus Sevens were factory produced too, but they gained a wide audience by folks who build and modify the original design, and modern G4 lineal descendants are often built as kit cars.

Lotus Sevens and Ginetta G4s were always primarily factory produced vehicles but a lot of the passion behind them came from later adaptations.

And there's nothing wrong with kit cars.

[hombre3000]

@MrGospelMan They're not kit cars. They have been sold without engines, yes, but they are factory-built cars. True, people build them with many engines, but in vintage racing, it must be at least period-correct.

I own one. I've been to the factory. I've met the Walkletts. I've been to a Ginetta Reunion. The kit car comment really gets to me. Sorry to get defensive.

@hombre3000

Well not all these cars ARE old. They're closely comparable to the Lotus 7. Especially owing to their kit-car heritage, people build them with all sorts of engines. There are plenty of G4 chassis being built right now around the world. Just based on performance though this does strike me as 100-120. I may be very wrong.

Take care hombre.

[hombre3000]

@MrGospelMan Ok, you got me! That said, from what I know, these cars used Ford, Lotus, and BMC engines, and even though these cars are old, most owners have done a lot of work/rebuilds on their motors.

Because of the big cooling demand peaks, high-performance cars rarely had low drag coefficients. The G4 doesnt have drag-inducing wings or similar, being as old as it is... but I'd guess a Cd of <0.35

The opponents here would be perhaps 0.4

Cd.A = F (Drag force)

This is a 1600cc I4 engine, so almost certainly the old (original?) Ford engine, which would make sense in a historical racer. If that's the case, and im sure it is, its original whp rating was around 110. Less over time.
