Re: Trofeo
Bravo,
Elle n'est QUE piste, ou aussi homologuée route? (je suppose que non, mais l'usage en est du fait très limité)

Re: Trofeo
Salut Pierre ! Uniquement homologuée pour un usage piste. Voici sa présentation par Maserati à l’époque :
MASERATI TROFEO GRANSPORT
Overview
The Maserati Trofeo GranSport is the racing version of the Maserati GranSport. Built at the Maserati factory in Modena on the same production line as the GranSport road car, the Trofeo GranSport was designed to offer the competitor an easy-to-drive car that is rapid enough to more than stir the emotions on the race track.
The 4244cc V8 engine produces 425hp compared to the 400hp of the GranSport in a car that weighs 240kg less than the production car. The V8 is coupled to the six-speed Cambiocorsa transmission of the standard road car, which allows the driver to make the most of the power without compromising the torque. The car’s ride height has also been reduced by 50mm, lowering its centre-of-gravity and improving its handling.
Technical specifications
ENGINE:
Total displacement: 4244 cc.
Maximum power: 425 hp at 7,200 rpm.
Maximum torque: 460 Nm/ 340 lb ft at 4,500 rpm.
SIZES AND WEIGHT:
Length: 4523 mm (178.1 in)
Width: 1822 mm (71.7 in)
Height: 1305 mm (51.4 in)
Wheelbase: 2660 mm (104.7 in)
Front track: 1525 mm (60.0 in)
Rear track: 1538 mm (60.5)
Front wheel rims: 9 x 18 in
Rear wheel rims: 10 x 18 in
Fuel tank: 100 litres (21.9 imp. gallons)
Dry weight: 1340 kg (3014 lb)
PERFORMANCE:
Top speed: over 180 mph
CAR SET-UP
In adapting the road car for the track, the engineers concentrated on various aspects. As with all competition cars, the engineers have worked hard to reduce weight, optimise the performance of the tyres (thanks to the tests conducted in collaboration with Pirelli from the earliest days of the project), the brakes, suspension and the gearbox, toughening them up for intense and prolonged use on the track. The car has been prepared in line with FIA regulations for participation in the GT championship, though the decision was taken not to make the modifications too extreme. The car has also been re-worked to ensure that it can be built on the standard Maserati production line.
The dry weight is 1340kg compared to the 1580kg of the standard model. This reduction was achieved through extensive work to remove all non-essential fittings in the interior and some from the exterior. The air conditioning unit was removed, as was the sound proofing and various smaller items. This work brought about a significant weight reduction. The side windows were also substituted with plexiglass panels, and the sound damping material was removed from the bonnet.
Like the road going version, the Maserati Trofeo GranSport is fitted with an F1 type gearbox with steering wheel-mounted paddles – the system is called Cambiocorsa. The ‘Sport’ setting used for the gearbox allows gearchanges to be made in less than 150 milliseconds. Some software parameters have been modified in order to optimise the response, for example, to improve the effect of engine braking.
The oil pump’s output has been increased for the rigours of competition, while the set-up of the differential has been altered to maker the car easier to manage on race tyres, and more fun to drive. Making the vehicle as safe as possible was one of the main priorities: only the highest quality and best performing components were used. The clearest evidence of this is in the braking system and the roll-over bar.
Brembo brake components have been used - during the FIA GT Championship they have consistently provided reliable braking and unparalleled resistance to fade.
To guarantee the highest levels of crash safety in the cabin, the Maserati Trofeo GranSport is equipped with an OMP roll-cage that conforms to FIA regulations, an automatic extinguisher, an anatomic seat with a six-point safety belt and an FIA approved secure fuel tank of a type usually found only on aircraft.
A lot of time was spent on the track during the Maserati Trofeo project, with the engineers aiming to achieve a reliable yet high performing set-up on all types of circuit. They focused most of their attention on the suspension. The flexible joints were removed, some elements were redesigned and the shock absorbers were modified - thanks to the collaboration of Sachs. The springs, now specially calibrated, were adjusted, reducing the ride height by around 50 millimetres.
All the cars have identical engines with certified torque and power. The only changes to the V8 have been made to suit the track: the car now sports a revised exhaust system to bring it up to FIA levels; a track-ready oil sump and a reworked ignition and injection system.

Re: Trofeo
Et donc, pour un usage piste uniquement, ça suppose une intendance assez lourde: plateau pour la transporter, garage ad-hoc avec pièces et peut-être pont. Pour quelques jours de track-day par an...tu es visiblement un passionné qui va au bout de la logique.
Comme je t'envie! Pouvoir faire de la vraie piste avec en plus un engin performant et le rugissement dans les oreilles, il faudra nous faire partager avec des vidéos, je te souhaite bcp de plaisir.
Est-ce qu'éventuellement elle peut être homologuée route moyennant des ajouts/modifications et un passage aux mines individuel?

Re: Trofeo
Je me fais peut-être des idées, mais j'imagine qu'il est possible de faire "light": un plateau, 4 pneus slicks sur jantes, 4 pneus wet sur jantes, un cric hydraulique et quelques jerricans de SP 98 dans le coffre du break, et c'est parti !Froggie a écrit :Et donc, pour un usage piste uniquement, ça suppose une intendance assez lourde: plateau pour la transporter, garage ad-hoc avec pièces et peut-être pont.

Pour rouler sur route, je pense qu'il faut absolument déposer la pelle à tarte arrière, sous peine de risque de blesser un passant, et remonter significativement la suspension, sans quoi le moindre gendarme couché sera un enfer. Et utiliser des plaques de circulation U, réservées aux garagistes pour les testes de voitures non immatriculées, pour éviter les foudres de la maréchaussée. Au minimum

Re: Trofeo
Félicitations Blu, elle est superbe cette 4200 Trofeo .
J’adore la livrée. Bon il y a du boulot sur les freins mais rien d’insurmontable.
Je rappelle à tous que Blu Sera est un bon pilote sur glace. Il avait même remporté une course sur Honda Prelude, prélude à la Maserati Trofeo !
Tu vas te régaler sur piste. Bon la trofeo sur glace, je te déconseille quand même !
A un de ces jours au Castellet ? Il y a de fréquents track days.

Re: Trofeo
Hello, des nouvelles de cette remise en route ?
Re: Trofeo
Tout récemment, les contres-portes en carbone ont eu droit à un petit lifting, et la lame avant, qui avait été abîmée et sommairement rafistolée, à été consolidée et remise en état :
Voilà pour le moment
AF Corse, qui avait préparé la voiture à l’origine, était probablement trop occupé à gagner Le Mans pour répondre à l’e-mail de demande de renseignements sur les pièces d’origine et les stickers d’origine du Trofeo. On reprendra la question après les vacances !
