I know they can be altered by size of pulley wheels etc , so why not go for a big un and alter it to suite ?
Specially with your knowledge !

To make ultimate power turbo is the way.

Or a paxton supercharger via a inter cooler.

As compressing air makes it hot and there is no intercooler on a root set up.

for looks its a roots blower.

6/71 blower is a little bit small for a 440 i feel but will work.

8/71 is just right

10/71 or 14/71 are massive and would not be running in there sweet spot.

BDS are the name but there customer service is crap and very unhelpful.

Any other day i would have walk away and said Bananarama! you. But i wanted BDS so bit my lip.

Blower shop as my second choice

There are a few 2nd hand cheap blowers out there but 1500 quid for a might work blower was to much a risk so went new.

so i brought new.

Think mopar mark still have a blower for sale which is very nice. (only reason i didnt buy it was its black and had my heart on polished.

Hope you got deep pockets im financially hemorrhaging

Is this for the show car Trev? How about finding a shagged case if it's just for looks and do a dummy set up, a proper 8/71 is gonna cost several grand...

Most of the old show cars were non runners, most had bare blocks and trans cases.

whoops sorry guys this isn't for a mopar, well it is sort of my 440 is finding a new home in a radical model T show car (I await the abuse) Blue, I had thought of that but if I can get a blown 440 in a car that weighs nothing and looks stupid it could be fun

don't worry im not giving up on the mopars just have the chance to build a car ive wanted since I was a kid

PS Blue, it will be on the road so wont be just a show car.

The bit I don't understand the blower bit on a 440 - other than the look, which is great.

You can put a standard 2 bolt bottom end under excessive stress without resorting to a Supercharger, so how do you make safe, reliable power on a block that has definite limitations when you get to around 650 - 700bhp? Girdles and billet caps will only give you a margin more strength.....

It would seem that you have to build the engine in a low state of tune to safeguard the block, which seems to me to negate the purpose of having a Blower (unless all you are after is the "Look") in the first place.

Discuss...

As said ultima power is to be made from turbo chargeing which allows for cooling of the Inlet gases.

Anything around the 6/700hp mark regardless of booste its after market block time.

My car is built to hoon around Harrods knightsbridge not the 1/4

Efi is the way but you all still got carbs

A engine built with low compression pistons (i.e. 8.5:1 compression) and an underdriven blower (a 6/71 blower is more than enough for an application like this) providing under 8-10 psi of boost (6psi is probably enough?), will not really stress the block much more than simply boring/stroking it. You are just making the engine think it has bigger cylinders.

Keeping the RPMs low will help a lot too. A blower will make a big cam think it is small anyway. So the power will be all at sensible RPMs anyway. A mild cam will make power like a truck.

I was talking to Nick Butler about the engine in "Revenge" once and he said he actually used a cam from a Funny Car in it and it worked fine on the street.
