WHere BA XR8 bonnet bulge came from?

OzJavelin · 30-01-2006, 07:40 PM

Reading some of my old Mopar mags and came across photo of this '73 Dodge Charger Rallye (their spelling, not mine). Does the bonnet (hood) bulge look familar? I thought so ..

.. so don't say old Mopars never gave you anything!

Nah!, TC Cortina 6cyl.

I dont know, but I love it!

**Polyal** · 30-01-2006, 09:11 PM

it came from a lack of engine choices...lol

tough car but the "bulge" has been around for ages

64compact · 30-01-2006, 09:28 PM

it came about so that for racing they can have more air over the bonnet than under it sucking the car to the ground, if you put the same Bulge on the AU it would have cleaned up in the supercars.they just needed a good reason to have it there as remember the Supercar still runs the windsor. and doesn't need the buldge.

^^^oh my...I am sorry but you are mis informed

nothing was going to help the AU with respects to racing...ambrose had a hard enough time

Dave_au · 30-01-2006, 10:26 PM

It came from pedestrian saftey and ADRs regarding the distance between the top of the bonnet to the engine actually.

JC · 30-01-2006, 10:29 PM

Actually, it came from when an XR8 saw a XR6 with hair dryer!

**Polyal** · 30-01-2006, 10:30 PM

hmm im pretty sure the only reason it is there was because the head on the 4v's is simply tall.

yes clearence was needed but it was basically because the engine didn't fit.

the best things ford ever does seem to come from mistakes. XC Cobra is another example.

overhead cams gave it the bonnet bulge . on a side note what gave a cortina tc 250 one?

From memory someone on the old FF tried putting a standard BA bonnet on a Boss and it did fit - but the clearence to the bonnet was too small for ADRs

If you're talking about the side stickers, then maybe.

The actual bulge though is very different from the Ford one IMO.

I know its not identical either, but the Alfa GTV6 bulge I've always thought was kind of similar...

klawsterfobik · 31-01-2006, 12:26 AM

Agreed on the TC corty... i always thought they looked similar. The TC bulge came from lack of room between the taller 6cylinder engine and the bonnet; same situation as the Boss engine in the BA's

GlennBA · 31-01-2006, 12:50 AM

i'm pretty sure its because a flat bonnet won't fit over the boss engines.

When you've got big balls, you need a big "Hector" to protect them....

One interesting thing the Mopar bonnet bulge had that I don't think any other "immitators" had was the "air-grabber" .. a trap door on top of the bulge that could be opened to pull fresh air into the carb. Probably not very effective, but very '60s cool!

Yep thats right. I was told it wasnt even in the design of the BA but because of the lack of clearance a buldge was created. Best mistake in my words!

XA-Coupe · 31-01-2006, 03:31 PM

If you open an XR8 bonnet and look from the side across the guards you'll see exactly why there is a bulge. The actual shape of the bulge is purely for styling as the highest part of it is over where there is no clearance issue.
