Coronado Speed Festival 2009 Ginetta G4 comes from the rear in 3 laps to the lead

Love this little Hot-Rod!!!

[MrTopanga44]

this is a genuine round tube 1964 G4

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

[saintellins]

A good advert for American Muscle cars

Excellent video. Great driving and a great car (I would know).

You named the builders name on all the amc forums but I think you are here blowing your own horn again...what records did your SS/H amx hold I can't find NONE mr. Lee Bwhahaha

[superstockamx]

What excites me on this video is the engine is built by my engine builder and I have a new bullet being built right now. All the sudden, the long wait seems worth it! The owner of this Ginetta may not want the world to know the details so I will refrain from mentioning the shop.

I race a drag car and it is a Super Stock 1970 AMC AMX. So far we have set one record with this AMX but many more are set to come.

Jeff Kline, your one helluva driver!

[rcs240z]

This car is amazingly fast...compared with my video running a 2000cc Datsun roadster!!.... this is just scary fast....No doubt, Jeff can drive and that Ginetta is a rocket ship.

[shadmonk]

great race.. Amazing performance from the 1600cc ginetta. Is this car running IRS rear, and what do u reckon the BHP is....?

[hombre3000]

@shadmonk I would guess around 160 brake.

[MrGospelMan]

@hombre3000

I'd say you're over by 50. 100-120.

But it weighs under 1000lb so the power-weight ratio is insane, and roadholding has a nonlinear relationship with weight, so it can actually make use of it. That's why it keeps getting on the power earlier, staying on longer, and cornering tighter. The tiny dimensions mean it has less frontal area, and less drag at higher speeds, so it can keep up on straight sections.

G4s just ooze overtaking opportunities.

[hombre3000]

@MrGospelMan I wouldn't say it's quite that low but guess was definitely high. G4s aren't particularly aerodynamic in design from what I've heard, but you're right that they're tiny.

[MrGospelMan]

@hombre3000

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.

[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.

[MrGospelMan]

@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 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.

[MrGospelMan]

@hombre3000

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 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.

[shadmonk]

@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.
