I'm a bit embarrassed but I hadn't been to your website before before i made that post. I 'assumed' that this system did away with the factory valve setup. After reviewing your website it appears that you offer exactly what i was looking for in the first place. I will give you guys a call this week and about options and pricing.

On a side note, did you guys go out to PRI last week?

In the magazine road tests, the differences I've seen in the Vantage test results is no greater than the variations that Porsche test results show, so I don't think there's a consistency-of-quality issue. So many variables come into play, e.g., weather (temp and humidity), altitude, miles on the engine, test surface, etc. I seriously question the figures on the websites that seek to summarize the results -- there are so many opportunities for error -- and I give far more credence to the magazines that have been around for a long time and run the tests themselves. These magazine tests (and I've read every one written in English that I can find) show the V8S being just slightly quicker than the non-S -- about 1 mph through the 1/4 mile. That makes sense given just a 10 hp gain, which wouldn't show any improvement IMO w/o the slightly reduced weight and more closely spaced gear ratios.

There are no differences in the magazine tests b/w the manual and the 6-spd SS systems, but the 7-spd should have a slight advantage. I'd be stunned if the Power Pack will get an S to 500hp. You said "close to," so I guess it depends on your definition of close Look at what Bamford Rose has to do to get 500hp.

Still wondering whether the earlier OEM exhaust is any "better" than the later one...

 

No worries, we're back to being the new kid on the block. Feels like 2007 all over again! I'm sure we can figure out something that works for you.

PRI, no we weren't there. Did have some stand space at SEMA though.

 

Don't ever see them being assembled in Germany..Too much money in the Gaydon factory to up and lift..I mean they up and lifted the Rapide from Germany to now being built in Gaydon...Engine's have been in Cologne and will most prob be changed to a Benz plant..doubt a bespoke benz will be built under a ford room..haha

As for the "comparing" a V8VS to V8V acceleration 0-60 is really pointless..V8VS 7-speed has a final drive of 4.182:1 and the V8V 6-speed has 3.909:1..even with the same power and same driver etc, the 4.182:1 will always win 0-60..

I've driven the full Velocity kit with tune..It is impressive but not near the seat-HP feel of a V12V taking off with traction klike some are hoping(hehe..if you can find traction that is), ..driving the V8V ASM Velocity fitted vehicle I had compared to the same alike model, year and options.. hands down Velocity upgrade is felt in your seat-HP and heard, if you had the cash, I would recommend it, just the headers are not a regular DIY install for the regular guy with hand tools unless your doing a complete winter project

I'd settle for 480-490

 

Yes, it should. But the difference, even with an additional 10hp (not enough of an increase to make much difference), should be very slight, which is what the magazine tests reflect.

Jay,
480-490... You're easy to please

 

[QUOTE=jaymoney;4003496]Not if you talk to my wife

 

[QUOTE=jaymoney;4003496]With the right tune, I think 480 is achievable. Bear in mind the 'S' has some software changes that probably take a little of the gains away, but I'd have to agree with the sentiment of the thread in general. The 2009 cars look like a great platform to tune from right now, both because the value for money is there on the purchase, and because putting a little bit of the money saved between an 09 and a 13 into some breathing mods will give a noticeable boost.

BTW - I've not heard back from the 6speeder who expressed an interest in a 4.7L power pack at a discounted rate + Velocity pays for the dynos. If someone wants to step up I might have a cracking deal for you.

 

gear ratios don't give power. you don't know until you research, whether the 3.9 or 4.1:1 final drive will be more effective in utilizing the power. if you end at the rev limiter at 60mph, that gear box will be best, regardless of if it is a 3.91 or 4.1. its all about area under the HP curve used.

 

Agreed, gearing alone doesn't mean anything... Especially if first gear ratio is longer in the 7spd then that negates any advantage.

 

I'm scared to ask what the offer is. PM ME Stuart! Wait don't. Wait yes. Wait....

 

Never said in my rambling that gears give power..I wouldn't of wrote unless I "researched"...

6-Speed:
1st 3.15:1
2nd 1.95:1
3rd 1.43:1
4th 1.15:1
5th 0.94:1
6th 0.76:1
Reverse 2.38:1

7-Speed:
1st 3.286:1
2nd 2.158:1
3rd 1.609:1
4th 1.269:1
5th 1.034:1
6th 0.848:1
7th 0.675:1
Reverse 3.286:1

If you took a 2009 V8V and ran it with a 6-speed ASM..then removed and fitted a 7-speed in place and ran the same tests..the 7-speed would net a faster time in the 1/4, better time in the 0-60..and faster final top end speed..hense why i stated in my original post.."You can't compare" ..even with the ratio's sligthly off for each gear..there not far off enough to go with your explanation..it's a street car on the same engine just different gearbox
