V8V Heel and Toe

[ian_uk1975]

I think this is one case where the Sportshift has a definite advantage over the manual... heel and toe in the manual is almost impossible due to the extremely lethargic throttle response. Has anyone found the same?

The only way I've found to rev match on downshifts is to stab the throttle pedal to the floor. Anything less than that and the engine just doesn't respond quickly enough.

Aparantly combination of twin plate clutch and lightweight flywheel is the best way to improve this. Engine box volumns affect but his too. Mike from Bamford Rose could explain why with more technical detail. Worth ringing him if he doesn't ping a reply on here.

I am not a race car driver but I do heel toe in my V8GT.

I would ask first do you have the 4.3 or the 4.7?

The above response is spot on I find the twin plate clutch transforms the car.

Even in my 4.7 it needs a bit of poke if you are under 4k rpm... above that it's sublime when you hit it right ... rewarded with that song!

You may find an ECU flash as an alternative (cheaper) method to suit what you are after.

I found changing the accelerator pedal to a slightly larger one helped and got one shipped from Ultimate Pedals.

Speak with Bamford Rose as they will be able to best advise.

Yes forgot to say that TP clutch setup comes with throttle response re-map.

I had the V12V Sport throttle map put on my DBS because H&T was completely impossible.

I have a 4.7 V8V and found the throttle response sluggish until I had Larini 200 Cell Cats fitted. Can't say I'm a skillful exponent of heel & toe as my right ankle never seems to be that supple!! However, just blipping on the downshifts is so much faster now and ultimately it sounds superb.

Same for me. Got a 4.7 and although I could heel & toe it did take a little more of a prod. Had KH 200's fitted and seemed to work a lot easier.

Could you elaborate? Does this mean the throttle body vs throttle pedal map, or some other map function? Is it a V12V map while in sport mode, or a map from the V12VS?

[dbs2000]

Yes, Mike from BR put the V12V Sport mode throttle map on my DBS to liven it up. It makes a massive difference.

Really depends how far you want to go. I had had Bamford Rose fit twin plate clutch, lightened flywheel, manifolds and 200 cell cats at same time. Awesome! But I also had them remap the throttle to a H&T specific map which does away with the horrible bit at the top of the throttle travel that doesn't do anything. What I can't do is tell you the relative contribution of each mod but as a package it really does transform the car. If you want your car how it deserves to be then do this. Oh and don't forget the fast road geo and quick shift gear linkage mod

Properly expensive to make performance upgrades to an Aston, compared to most other cars it seems... I dream about my Vantage having the throttle response, light clutch, quick snickety gearchange, and power to weight ratio that my Chimaera has, it would be awesome and probably all I ever wanted or needed in a car.

But the truth is, I love it how it is

Although, when it does need a new clutch it will get the twin plate and lightened flywheel jobbie...
