Le BTS forum du CCF, tu l'as aussi?

Jack dis à ton Patron de se magner d'atteindre les 100 posts et de venir au HRCB. Je pourrai te filer un coup de main et lui régler son compte !

Faut pas pousser quand même, votez Arlette!!!

trop vieille Arlette
plutot le facteur ,lui il a des dents de re**in pour mordre

quelle dérive!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

du loobysme agricole pour nous ammener dans une souricière fiscale comme d'habitude !! ( regardez l'évolution des tarifs du bio depuis 2 ans ):spiderman: le monde agricole français est sur..subventionné ! faut bien sortir de l'ornière ..quitte à ce que nous importions du blé chinois ..pour nourrir notre future génération .. n'oubliez pas qu'en % relatif les corvettistes ne polluent pas grand chose ... une mobymatic jaune d'un facteur ou une aixam "sans permis" sont + polluants ...
bonne journée ... jvous prépare la wodka ??

Voilà un sujet qui est bien parti pour finir au HRCB !

scuse leshark desfois tout m'énerve ! je vais prendre ma carte de pêche et titiller le gardon ... plutôt que de perdre le carton ... avec points ... bonne soirée ..
alain :slap:

Pas du tout, il faut bien faire vivre le HRCB !

Ben oui, on manque de voyoux.

Finalement, il n'y a que des gentlemen ici! contre toute attente?

il suffit de basculer les derniers posts dans HRCB

J'ai trouvé ca pour relancer un peu le debat. Le but etant bien de rouler plus perfo et moins chere....

First off what is E85? E85, is a motor fuel blend of 85 percent
ethanol and 15 percent gasoline to be used in flex-fuel vehicles.
Ethanol is alcohol used in transportation fuels. It is a high-octane,
liquid fuel, produced by the fermentation of plant sugars. In
the
United States, ethanol is typically produced from corn and other grain
products, although in the future it may be economically produced from
other biomass resources.

Benefits:
It has a motor octane
rating of 104-108, it is also quite cold to the touch. It is currently
about 1.99 per gallon, while 91 Octane is approximately 3.30 a gallon.
E85 is cleaner burning, emitting a lot less greenhouse gasses. It is
also a renewable resource. To top it off it is made 100% within the
confines of the USA.

Cons:
It takes more of this fuel to
create the same energy as regular gasoline. Therefore your car will
use more fuel and you will see a decrease of approximately 10-15% in
fuel economy. To make big horsepower you will need more fuel pump and
more injector. Many people state that the fuel is corrosive and it
could have adverse effects on aluminum fuel rails, injector o-rings and
fuel lines. But so far in 9 months of testing we have seen no such
side effects.

Test Car
1995 Mustang GT street car, 331 cubic
inch, custom twin turbo system with twin T70 p-trims w/ .58 AR, T56
tranny, solid roller: 242/236, .600 lift.
Fuel System: 3, 255lph Walbro in line fuel pumps, 160# injectors.
No alky, no nitrous, no ice on the intake, etc.

The
first thing we did was add 40% fuel to the fuel map under WOT. We also
added about 20% fuel in part throttle areas. We were tuning using a
regular gasoline wideband air fuel ratio of 14:1 at part throttle. On
the dyno the car made the best and cleanest power at 12:1.

At 6
psi of boost and 35 degrees total timing the car made 575rwhp from
6000rpm until 7500rpm. The power never fell off. We tried less timing
but the car didn’t respond well and the power curve was sloppier. At
13psi and about 29 degrees of timing we made 872rwhp. At 20psi and
~24 degrees of timing we made 989rwhp.
At 30 psi and 20 degrees of
timing we ended up with 1066rwhp. The fuel injectors were at 75% duty
cycle at this power level. Whereas with gasoline they were at about
55%. The fuel pressure was also slightly falling off at the top. The
lack of a large power increase from 20-30psi is due to the tiny exhaust
housings on this street car.

In total we made 16 dyno pulls and
we never heard any detonation, but we did hit fuel cut a few times
during testing. The next day the spark plugs were pulled and there may
have been slight detonation in 2 of the cylinders because the porcelain
was speckled. However the car still runs fine. This is definitely a
very impressive fuel.
I also want to point out how impressed I am
with this solid roller setup. Sure it is slightly noisier than my tiny
hydro cam. But you can’t argue with that sick power curve. At all
boost levels the car makes peak power at 6000rpm and holds it solid
until 7500rpm, I am sure it would pull up to 8000rpm no problem. Steve
has also tried a larger hydraulic cam to get the same results but it
just didn’t work. The cam was a comp extreme energy hyd roller: 248 @
.050 on int and exh, 114 lsa. The car also had larger 74mm turbos at
the time but the power would peak at 6500rpm and drop like a rock, even
with expensive valve springs. With the new small solid roller cam the
car even lugs along at 1500rpm no problem and idles fine at 900rpm.
