From what I could find in magazines online, Motortrend states “Nonetheless, on its first run the Aston had clocked a 0-to-60-mph time of 4.1 seconds and a quarter mile of 12.5 seconds at 115.0 mph, easily bettering the 4.3-liter car's performance (5.2 seconds; 13.6 seconds at 105.8 mph) and even topping the times of the mighty, 520-horse DBS with six-speed automatic (4.2 seconds to 60 mph; 12.6 seconds at 112.3 mph in the quarter). ”

what more do I need to do to my manual 06 to make it faster than the 4.7? I currently have the Aston Martin power pack (supposed to add 20hp) and tubi style exhaust. My Harrison signature high flow cats just arrived and hopefully installing this weekend. I ordered a velocityAP tune and high flow filters through the Black Friday sale. Will this get me into 4.7 territory?

Looking further ahead, is there a reasonable path to get the 4.3 into Mercedes amg gts territory? I was able to run 11.8 @ 122 in the amg gts but decided to exit that car as I wanted to be back in a manual transmission.

 

You'll always be playing catch up. These cars are more than just about 0-60 numbers and straight line speed...

If that's all you care about..get a Tesla.

That being said, stage 1 mods (intake/tune/HFCs) should put you on par with 4.7. If you want to outrun it, you'll need to look into headers and maybe lightweight flywheel/clutch as well.

 

I don’t have it nor know anyone that does but GMR makes a supercharger for the 4.3 that will likely scratch your itch if it delivers as advertised.

while likely require some homework on installers and you’ll for sure need an upgraded clutch. But likey way cheaper than getting a V12 manual.

 

The sane path is just bolt-ons.

I have the following:

Aston Martin ”Power Pack”
Tubular headers
High flow cats
X-pipe
VAP Valvetronic muffler
VAP high flow filters
VAP tune

That’s basically the whole list of easily available modifications. Should put you a few percent above a stock 4.7.

Weight reduction (2 piece brakes, lighter wheels, part removal, etc) helps as well. The lighter flywheel makes a minuscule theoretical gain, too.

The GMR blower seems like madness to me, but I build turbo cars so spending 5x the cost of turbocharging it for less power just seems silly. I’ll turbocharge your car for you for way less than 20k! Hah!

Either way, turbo or supercharger would be your next options for more power. A head porting and custom cams is probably worth some also, but likely not worth the cost/HP vs forced induction.

Long way of saying, do some bolt on mods and enjoy the car. If you want something particularly fast, buy a faster car.

 

For the street, the advantage of the 4.7 engine is not the horsepower advantage, it’s the torque advantage. Bolt ons will not get you more torque, but it will get some more horsepower. Note however, that horsepower will be in the upper limits of the RPM range, and will be of little use on the street.
The 4.3 engine does have one advantage, it’s stroke is shorter and it will rev faster and higher, so in theory, a 4.3 engine at 8000 RPM (with the proper camshafts) would produce more horsepower than the equally modified 4.7 engine at 7000 RPM. The reality is that street cars don’t live at 7000 or 8000 RPM. If you want more horsepower than the 4.7, then as some have suggested, headers, removing the secondary cats, modifying or removing the air cleaner boxes and a ECU modification ( tune) should get your HP equal to or somewhat more than the stock 4.7 engine. Disadvantage is that you will lose some mid-range torque, but you will gain some bragging rights (smile)
I should note though, that if horsepower is of primary importance to you, then you bought the wrong car, be it the 4.3 or 4.7

 

150 shot will do you for 1/8 & 1/4 mi. times. I have not seen or heard of anyone doing it but someone needs to try it. Wet system is the way to go.
