Cosworth bottom end

If it's fast then i suppose it's alright though

 

That my friend has got to be the most sensible thing you have ever typed

 

Notice the sensible cautionary "though" on the end though...

lol , believe it or not i already own a few oldskool turbo motors (well in bits and scattered around the place) so i'm not exactly anti-turbo . I wouldn't mind a supercharger for a change though

Supercharger is different-ish… and footwork has been done before - I’ve heard of supercharged pintos & x flows (and lots of other engines) using the M45 but think the Eaton, all in, costs a fair sum and setting up isn’t as straightforward as all that …

 

The idea is they provide the perfect amount of air into the engine each time the valves open... Apparently the aim is to get 130% as this is the most efficient level, allowing it to burn more fuel in a given cycle and produce more power. A normal N/A engine is about 70-80% (but the more you tune them the better it gets - as u know ).

 

They rob horsepower to run them though…….. but you are supposed to net a lot more than the loss.

 

U should size the charger to suit the engine size. There is no big kick of power like a turbo, just seamless torque and decent idle/cruise ....

 

Lots on the Internet for research if anyone’s interested under ‘Eaton M45’…

Nat from here has sucessfully used one on his Pinto Capri. On a recent dyno, he managed 199bhp it think! That is FULLY home built. I think the spec is something like 2.0l, Injection Head, 38DGAS, FR32 cam & megajolt ignition. Haven't been in it yet but hope to at this years COC. Honestly guys, what Nat has acheived on a student budget with no proffesional input is amazing

That's really positive...

 

So, roughly, the home built 2.0l, Injection Head, 38DGAS, FR32 cam & megajolt ignition will give you 130hp so the home installed Supercharger has added 69hp... Respec'.
