The advantages of our bellhousing over the adapter plate are :-
It allows use of the full size Ford flywheel and clutch which is much larger than that used with an adapter plate
It allow the use of the Ford small block starter which is more powerful than the starter used with a plate set up
It converts Renault 20, 21, 25 and 30 transaxles direct to Ford 289, 302 and 351 windsor blocks. A plate set up requires the use of a 25 or 30 V6 bellhousing which is a pain if you have a 20 or 21 transaxle.
We also have a version which bolts to the Coyote V8 as used in the 2011 Mustang.
The bellhousing totally eliminates clutch slip and hot start problems.
Thanks

This question sort of depends on what you have now. Lets start with assuming you don't currently own anything and haven't decided on how much HP you will want from the motor.
In that case I would spend the money and buy a big bellhousing (ford to renault) and use all Ford parts, flywheel, clutch etc. You will not be limmited by the small diameter renault clutch and it's limmited torque rating and your won't need to find a small flywheel to fit the renault bellhousing and reballance it for your motor etc.
The renault single plate diameter will give up at about 400ft/lbs no matter what you do. Mine is a renault pressure plate with beefed up springs and a 4 puck friction disk. My motor makes about 350ft/lbs and the system I am using works very good with my medium power motor.
If I wanted a lot more power the first thing I would do is figure out the clutch that would be necessry.
If you already have a R21 with the renault bellhousing and a small flywheel ballanced for your motor and the motor is making less that 400Hp then I would work with what you have.

The original Renault clutch was designed to take 130 BHP and 150 ft lbs of torque
Most GT40s these days seem to have around 400 BHP and 400 ft lbs of torque.

Hi,
most available bell housings ( I use the one supplied by tornado ) have the clutch cylinder to close to the exhaust...Over time the heat will kill the rubber seal inside....not on the first ride...but sooner or later...I already lost three of them .....But I am not using the crossover exhaust design...so I am not saying this is a fault by the Tornado Bellhousing design, it might works with in combo with the exhaust supplied by tornado......But the design limits you a lot if you want to play around with the header design and lower headers to keep heat away from the rear hood.......
With the clutch, Howard is right....
Cheers
