Finally Posting My Vantage
 

I have been visiting 6 speed for years but never posted my car.

Proud owner of the following 2007 SS AMV8; with many modifications. currently pulling between 420 - 425 hp

Kahn RSC wheels: powder coated black
- 20 X 11 rear (w/ 295/25/20) with 3mm spacers
- 20 X 9 front (w/ 255/30/20)

Lowered 1 inch by AM dealer: H&R springs, improved handling and stance

Carbon Fiber: mirrors, rear diffuser from RSC

Carbon Fiber front spliter: Autosport Design

Tubi stage one exhaust:

Aston Martin Factory updgrades:
- N400 power upgrade kit (air box, new ECU, fuse box,
etc)
- N400 side skirts

Additional power mod: RSC ECU remap (big difference in power)

Smoke tail lights and corner lights

RSC 200 cell count cats installed, and they are fantastic.

Greater power in the midrange. Without dyno numbers (seat of the pants) it feels noticeably faster than the 09'4.7 that I drove.

Great products from RSC!

sick looking Aston! welcome

welcome and great looking car ,i have the same wheel tyre and suspension set up as yours

Sick lookin car! Gread Mods

I like the convex look!

It looks sinister... but classy, just like an Aston should.

Hershel and Stewart:

love the ECU remap, car is definitely more responsive. Thanks for the quick turnaround.

Can you send me info. (specs, perforamance dyno) etc. on adding the 200 cell cats.

Has anyone installed these yet? Any issues? Performance changes?

thanks, Jeff

6speeder rmrmd1956 has got these on his supercharged vantage and has confirmed 20RWHP - on a normally aspirated car that works out to 20BHP which is a consistently achievable figure. Not sure exactly what your car would make with the ECU, cats and the Aston upgrade as we haven't got a figure for that.

Throttle response is greatly improved, more aggressive sound than just the exhaust (both volume and quality of sound - more raw) We have never had a set of these catalysts throw a code and that includes Vantages, DB9s, DBS, and the aforementioned supercharged Vantage. Not the case with some other products on the market - I know rmrmd1956 had to change over from another company's cats to ours because they kept throwing codes.

PM me with your number or email Stuart@RSCtuning.com and I'd be happy to give you a call to discuss further.

Perfect.

Super nice, well done
Want to asked than with the factory upgrade, why still need the RSC ecu remap? Are they doing the same thing?

Yeah I wondered that myself. Presumably the RSC tune is more aggressive than the power kit tuning, and much of the power gain in the power kit comes from the revised intake.

Looks just about perfect Jeff. I love the N400 sills...should have mine on in a few weeks.

The wheels look like the RS-Vs, not the RS-Cs. They look great but they've gotta be heavy...did you feel a difference vs. stock?

Thought everyone might like to see this shot - have had it on my phone for a few weeks and just didn't get round to downloading it. This is a side by side comparison of the RSC cat with the OE cat. You can see why these are worth more than a couple of horses, the OE pieces are clumsy, restrictive and built to a price. You can also quite clearly see the heat ring on the OE cat from where it has overheated and begun to break down the internals. There's so much kinetic energy contained in the hot and rapidly flowing exhaust gases and the more restrictive the cats are the more of that heat gets transferred into them.

I love the addition of the N400 side skirts! It really complements the rest of the car well.

I must be missing something. If someone asked me which cat was more restrictive, it would be pretty obvious to me that the one on the left is, having significantly less volume than the one on the right.

Do you have flow test numbers to back up your claim?

The volume inside the catalytic converter is filled with substrate that restricts flow. The smaller the volume, the less restriction. The rest of the high-flow cat is simply straight through tubing that allows the gases to pass.

You are correct about the ECU from RSC. The factory upgrade is about 20 hp, mostly due to the revised intake. The RSC ECU upgrade is about 30 -35 hp over stock; throw in the tubi exhaust for about another 5 -8hp. I really do not know how much gain I have with the addition of the factory upgrade N400 intake. Hershel or Stewart has dyno charts that they can post.

Thanks to all for the positive comments. From a beautiful car with fair performance, to a great car with quick performance. Next up the cats.

Don't forget the intake side. The stock paper filters are pretty restrictive and there is a K&N part that fits the car...supposedly good for at least 8 hp.

I'm also looking at ITG filters because that's what they use in the GT4. The ITG filters don't fit in the stock airboxes, so I'm seeing if I can get the GT4 airboxes as well.

Has anyone installed the 200 cell cats. If so:

Are they lighter?
How much more noise out the exhaust (I have tubi stage I)?
Have you ever had the engine warning light come one?
Can anyone post horsepower gains?

thanks, Jeff

absolute beauty...

Congratulations !
 

I like your style ! car came out looking fantastic! I would like to get some lighter wheels but I personally love the look of the stock ones. I have spacers installed on the rear and they look great. Question how do you like the H&R springs? and do you know if any of the TCU upgrades get rid of the crawl feature? Also do you plan to do the flywheel mod? That I heard makes the car rev a lil faster. Enjoy !!!!!!

JeffRB - I posted some info on 200 cell cats on other thread ...

Wow the OE cat is huge! A good friend of mine has a Vantage and I know the guys at RSC very well and am trying to convince him to do the power kit. It really needs another 50-100hp.

love it! those side skirts are amazing!

Spot on. The crucial point is that the entire OE cat is full of restrictive material, whereas the RSC cat on the left obviously contains much less. The diameter is not entirely relevant given that a smaller straight through pipe would actually be less restrictive than either of these cats. Having a wide pipe doesn't necessarily produce the most power. If you removed the exhaust & manifolds from an engine altogether it would actually make less power. The smaller the diameter of the exhaust system, the higher the exhaust gas velocity has to be to pass through it at a given engine speed. Because these gases have momentum they are actually instrumental in drawing air out of the engine post combustion thereby increasing it's power output. Go too small and you run into problems with air pressure becoming too high and the gases backing up and almost beginning to behave like a solid (this is where an expert in fluid dynamics is welcome to step in and explain why exhaust gases are normally almost behaving like a liquid etc. etc.) So the diameter of the catalyst exists in order to provide space for the substrate but in fact the sooner the diameter is decreased the better this is for the exhaust gas velocity.

More mods today
 

Thanks to Hershel expediting shipment of my new exhast, my RSC performance mods are pretty much complete. Today the 4.5 baffle exhaust was installed, to compliment the RSC ECU and RSC 200 cell cats.

All I can say is OMG (Michael you were right). The car sounds fantastic and is much quicker than before (and I have the N400 factory kit as the baseline). You guys at RSC said that the 200 cats would add about 20 hp. I wasn't sure, but once installed I became a true believer.

I drove a new 2009 Vantage, and my RSC'07 is appreciably quicker.

I thought that my former Tubi exhaust sounded good (and it did). But the RSC setup blows it a way, and is quite liveable.

Thanks Hershel, you guys make owning an Aston Martin a great experience.

I think this explains better than anything:

Good pictures Stuart - I try to explain the difference - "you can see through the 200 cells" - your pictures show the point in less than a 1000 words.

its our pleasure Jeff.. enjoy it and drive it.. have a good time in Monterey this weekend

very tastefully done I love it.

wicked aston!

I'm not disputing this, but it sure would be nice to see a head-to-head run.

The 09's have a lot of changes...more displacement, bigger valves, better breathing, lightweight flywheel, carbon fiber driveshaft, lighter wheels, etc. Lots of upgrades...and the numbers from Motor Trend were very good...0-60 in 4.1 and the 1/4 in 12.5@115. Was the '09 you drove a new one or was it broken in?

Any chance of getting a video of a direct run? Dyno?

Late to see this post-

Pure sex. That is a very nicely done AM. Love the design/black wheels. Congrats on a beautiful car.

The more I see of these Vantages, the more I am thinking of getting one. Probably one of the best looking cars in the world.

soooooo beautiful...i love the vantage...almost the perfect car...

gorgeous car... congrats!

Congrats..your car looks amazing!

They are the best looking cars on the road period. If it had more power, it WOULD be the perfect car. The interior, exterior, etc. is pure beauty.
