I wish that number were believable for Detomaso's sake, but it's just not. At the time of the dyno, his car had the AM power upgrade, filters, and an aftermarket rear box. Aston themselves say the AM power upgrade is good for 20 bhp (and they have no reason to sandbag on a product they're selling). I believe Stuart has said that filters and a free-er flowing muffler will only add something like 5-8 bhp each. So, even being optimistic, that would be a net gain of 36 bhp, or 416 bhp total. Don't want to rain on any parades, but these numbers just don't make sense, and don't match up with other people who have dynoed their cars over the years. I wonder if the dyno that was used is in need of calibration.

 

I'm no expert on dyno readings, but it seems that the only number that really matters is the number of horses that make their way onto the road. The ones that lose their way in the transmission don't make the car any faster, so why count them?

If there was a way to cut transmission losses by 20bhp, then that is worth about the same as a 20bhp power increase. [OK, I know the arithmetical flaw in this argument, but the principle has to be right]

 

I agree. RSC and Stuart are great. If you're considering rims though I'd recommend staying away from ADV.1. an 8 week build is now going on week 14 and still no rims. The company is not very responsive to customers and when I tried to modify my order (very early on) I was told it would be almost a grand to re-engineer them because they were so ahead of schedule on them. If this is way ahead of schedule then I'd hate to be on the other side of the coin! Anyways I should finally get them in a couple of days. I'm sure they'll be pretty awesome in the end, but I'm a big fan of good customer support, and after paying in advance $11,000 for rims, I'd at least expect a return email or phone call from ADV.1 when I inquire to their ETA. Just saying.

I've got the RSC 200 cell cats, touring exhaust, filters and ECU remap. I'm very happy with all of it.

 

Thanks for all the input for a newbie like myself. Personally, the actual numbers don't matter to me, if they did, I would buy a Porsche and move on. I love the car and the drive is awesome, I just want a little more fun and some growl! On that note Aston 007 mentioned RPI and a eurocharge tune. What is that?

 

Aston Martin of Dallas installed an Aston power pack upgrade, DBS wheels/tires, clear taillights, Larini complete exhaust (cats, box, etc.) and radar detector. They did a great job on all of the mods and stood behind any issues (there were none). I was happy with their work.

You can also try Steve Fordham at Autoscope in Dallas if you don't want the dealer to do your "tailoring" of the Aston. Tell him that Scott Black sent you and he will make sure you are well taken care of at Autoscope.

 

^^^ Nice job on the power pack upgrade...is this a standard package offered thru any Aston dealer or is it something offered only by Aston of Dallas to it's customers? I like the wheels on my car, already have the clear tailights (custom ordered for the car), already have a V1 radar detector, wondering if I could get the back box exhaust, cats are fine on the car for now....here's a pic:



I just picked this up over the weekend...it's a rare 6MT with slate Blue and Obsideon black and was actually the official Press car of the 2007 LA auto show, the dealer overlooked that little tid bit when they sold it to me they didn't know that...all they had to do was look at the sills, and the engine plate and run the VIN and they could have gathered it

 

My V8V had a paramount ecu flash, a quicksilver exhaust, and sports filters. The car definitely felt faster. I had the car dynoed before and after. I have moved since and can't find the sheets. I remember at the time, RSC was advertising an "R" package that brought the 4.3L to 443 HP that included cats but not filters. I don't remember the actual numbers because I was disappointed to find out that the gain to the wheels was 16HP. I anticipated 25. In hindsight, I realize that for that car a 16 HP gain to the wheels was pretty good. I have a feeling though, that it came primarily from the flash. Even the power pack from AM needed the flash to be effective. So I'm pretty sure that the same kind of programming could be done from a tuner. After Ford sold AM, the HP seemed to go up on all of the cars and I think that the bit of ECU tuning was wrung out. The biggest problem with all of this is the fact that it costs around 10K with installation to bring about a humble HP increase. Coming from the 911TT world, that kind of money gets you 50-75HP. I would love to hear from someone with the new Quicksilver treatment on a 4.7L. That is supposed to bring that car to around 485HP without messing with the ecu.

 

that's exactly what I thought also!!!

I am going to use my DB9 as a proper cruiser, a right GT car for which it was designed and built... heck that money put into my Porsche GT2 would turn it from the 550 whp beast it is into a scary snarly 800 hp monster lol ...I dunno what mods I will do to the DB9, we'll see for now I like the car as it is...I drove it 1200 miles back home this weekend, it's the perfect cruiser I was not a bit tired after knocking back the miles over 2 days of cruising on the highway!

one thing I will tell you...it already has RSC green air filters in...I had those put on within a couple of hrs of buying the car lol!!!

The Aston power pack upgrade on the V8V is available through any dealer. It is backed by Aston and does not void the warranty.

 

the eurocharge tune is a custom dyno-tune that 007 vantage developed with a tuner. It significantly leans out the over-rich afr and causes a large gain in hp compared to a reflash. It hasn't been out very long so I can't speak to the long-term impact it would have....

RPI (race precision inc) make an axleback exhaust for the vantage. It has a cross pipe so the sound is more complex and this help bolsters torque as well. If you like a more muscle car tough sounding exhaust, the RSC's sound great. The RPI is quieter and more multi-layered.

 

Hey guys, I've said it before but remember what a dynomometer is really useful for is measuring change (or Delta if you want to elevate the technical conversation to make yourself sound more authoritative )

They can all read differently from each other on different days, different weather etc. etc. So when you start talking about absolute numbers from one dyno compared to another dyno you're getting into some difficult areas...

The most important thing is - what is the difference before and after, in percentage terms. It really doesn't matter much whether the dyno says 200 or 400 HP before, if it says 220 or 440 HP after, then the change affected to the output is the same.

 

this!

I finally did my RSC cats and filter install and did a video today with some great sounds. Great day for top down driving!

 

One more...

 

Do you have the stock exhaust on her? Good to see another Hockey player in TX!
