Any Ideas For Group Buys? - Window shopping for blokes...

[Erko]

Yeah, gotta expect the marketing boys to come up with a lot of BS though thats their job. Agree that they could have done more with it however. But for an extra 1500 bucks you cant expect a lot. If it was 10k more, then you would have reason to blow up. Cosmetically, i am really happy with the white / grey effect and would have paid the extra for that by itself. The damper valving seems very good for road use, and better than stock for track use however its not of a Bilstein / Tein level. That said, i was always going to mod the suspension anyway

There R-SPEC specially built "trakpak" suspension may be a bit better but theres better out there, why didnt they put it in and make the car something thats worthy of the names they brand them with.....[/quote]




Dags, the Prodrive guys were utterly transparent about the design brief and went into detail about their cost constraints. The made no secret about the fact that they were just maximizing the valve performance of the twin tube dampers and seeking to invoke as much as possible a digressive response form the standard factory units. They even went as far as giving specific details about the sizes of the damper washer stack.

They then went on to describe what was achieved with the chassis and sought to describe the qualitative effect (feel) and put a number of the quantitative effect. (lap time)

No ducks guts where used in the chassis tuning. As I understand the press release it was done with damper mods.

R-Spec handling package

Prodrive Chassis Engineering Manager Peter Ford said his team were confident they have delivered a handling package that stayed faithful to the design brief. "We set out to create a dual purpose car; one that could be driven to the track, be competitive in a club event, and then comfortably carry everyone home at the end of the day. Fortunately, we had an outstanding base vehicle to start with. The GT already had great handling levels and the challenge was to find ways of maximising its inherent handling characteristics, while retaining a balanced set-up. The team sat down and looked at a number of options. Racing tyres and a competition spring set-up were two popular options early, but were dismissed due to the prohibitive cost of both. Research from customers showed us the cost of racing tyres, particularly replacing them, was out of their reach. And a customised racing spring set-up – the cost of which would have been significant – would have negative impact on the ride and handling of the vehicle, while also compromising tyre wear and potentially adding more cost."
Ford said his team sat down with engineers from Delphi, which supplies dampers for the FPV range.

"We had been thinking there was enormous tuning potential within the standard damper set-up, and the Delphi engineers were confident a sportier level of suspension tune was easily available. The traditional approach to twin-tube damper tuning is to let the compression, or base, valve handle damper forces in the compression direction and to let the rebound, or piston, valve handle the rebound damping forces. By allowing the piston to handle more load in the compression direction we learnt we could share the damping forces by both the piston and the foot valve. This had two immediate benefits, namely reduced valve lag and increased valve response," Ford said. The secret to the improved handling characteristics of the R-Spec package is the revised balance of pressures between the piston and base valve, resulting in a more progressive transition to disc opening speeds.

In addition, Ford’s team adopted a pyramid disc stack on the compression side of the piston, using disc diameters from 32mm to 27mm, as well as tuning the size of the rebound spring and piston orifices.

"The sum total of those changes is a suspension tune that is much more digressive and in line with tuning techniques used by prestige European marques costing much more than an FPV," Ford said. “We have delivered a suspension tune that offers a significant improvement in diagonal pitch, provides a much more even footprint in power-on situations and with a much sharper turn-in response. Critically, we have maintained an impressive level of ride comfort. While the R-Spec package picks up more road irregularities, we have maintained the supple ride that has earned FPV cars an enviable ride and handling reputation."
Track pack performs

While the team was happy with its outcomes, the real test for the R-Spec handling pack came in the hands of long-time FPV test pilot and V8 Supercar veteran John Bowe. The two-time Bathurst champion gave the R-Spec package its final approval in a test day at the demanding Winton Raceway.


"The initial impression of the GT is one of containment. The car feels tighter, sharper; far less inclined to roll and exhibits a big improvement in diagonal weight transfer," Bowe said. "Another strong positive is the difference the package makes to steering feel, creating a far more instantaneous response with added weight and feel. And the road ride is very good; firm, but not harsh and it handles bigger bumps amazingly well."


Employing the 19-inch alloy wheels and 245/35 ZR19 Dunlop SP Sport Maxx tyres that come standard with the GT 40th Anniversary edition, Bowe recorded a highly competitive 1:43.10-second lap time around Winton. While lap times are relative to the day and the driver, recent independent testing of an FPV GT puts the times recorded by Bowe – and the overall handling improvements achieved by the R-Spec package – into perspective. Fellow Ford V8 Supercar driver, Warren Luff, completed a 1:46.05-second lap of Winton Raceway in a standard FPV GT during last year's Performance Car of the Year testing by Motor magazine.


"The R-Spec package clearly delivers what the engineers set out to achieve," Bowe said. "For those customers that want to indulge in track days, but only have one car that has to multi-task, this would fit the bill perfectly."

aa is right there, its off topic, but Delphi actually came to the rescue here, prodrive told them what they wanted, and Delphi said they could more or less do it just by using the pyramid shaped washer stack, pretty clever and cheap!

[Erko]

ok, back on topic. Suggestion for GB

Super Pro front lower control arm bushes

[quote name='NOS XR' post='611839' date='Dec 20 2007, 08:33 PM']T56 for the Boss is shorter than the T56 for the Inline 6.

Good luck no finding a box that fits and works, I'll line up for one if you find the way to do it.[/quote]
is the box thats shorter? or just the bell housing that you un-bolt, shorter on the v8?????.

You will find that all the boxes are the same length, it is only the bolt on ends that are differant, Why would a factory tool up for differant sizes of the same thing, they use the same case and higher or lower grade internals. The best box runs i think 10 bearings and the next one 8 for example.

Hey guys, a while ago there was post about group buy on brake upgrades. did this ever happen? if not is anyone interested?

[Guest]

I'm looking for feed back from you guys please, while some of you at Summer Nats enjoyed smoking your tyers I was making a new friend at Crow Cams, he knew me already from the group buys on Under Drive Balancers here and on other Forums.

He has asked me to offer forum members here a cut price deal on Crow's Cams product range.

I can now set up deals on the whole range of Cams for BA-BF 6 Cyl and Boss engins.

Below are the Cams that Crow offer for the BA-BF N/A and Turbo Falcon.

[b]3231393A Mild profile Cams for N/A and Turbo 6 Cyl BA-BF applications.[/b]

Adv Dur on both Inlet and Outlet is 247

0.050" Dur. on both Inlet and Outlet is 185

Valve Lift on both Inlet and Outlet is 0.450"

Power Range is from 800rpm to 4200rpm


3231393B (Inlet) & 3241393A (Outlet)
[b]Medium profile Cams for N/A and Turbo 6 Cyl BA-BF applications.[/b]

Adv Dur on both Inlet and Outlet is 259

0.050" Dur. on both Inlet and Outlet is 195

Valve Lift on both Inlet and Outlet is 0.454"

Power Range is from 1000rpm to 4500rpm

0.050" Dur. on both Inlet and Outlet is 236

Valve Lift on both Inlet and Outlet is 0.510"

Power Range is from 3000rpm to 6000rpm


Custom grinds are on the table as well for both inlet and exhaust cams.


Trade price is said to be $800 a set of these cams and thats before postage and GST so the wa I see it they'd be very close to $900 a set to your door at Trade price.


At this point I think the price to your door will be close to $650 from this deal.

Please let me know if your into this deal.

Please note, I'll be away from the computer till next week as my wifes Grandmother pass today.

Thanks, NOSXR

I have this group buy set up and running on another Ford Forum.

7 sets of cams sold already with more buyers looking.

Wondering why members here on Turbo Forums arn't into more power?

[IEATV8S]

What sort of power gain are we getting with a new cam Any idea?
