A totally unfair but interesting technology comparison is a gas turbine helicopter engine at 450 lbs and about 2000 CONTINUOUS shp. | ||

At 1,300 rpm it makes 102 lb/ft of torque which is ~25hp. Redline is north of 11k rpm. Not sure what peak torque is. SWAG would be around 150. | ||

It would be a great engine for a Caterham as well. I have one that weighs ~1,170 lbs with a 2.0L Ford Zetec. It would be even better with this motor. It's probably weak on torque as Patrick mentions, but I'm sure it sounds amazing... | ||

How much torque does that engine produce? That would be a beast of an Elise...around 1300lbs now, or less, and 320HP...But the engine would upset the rear weight balance of the car. | ||

Thats kind of what I was thinking, the 340R is a very cool car but it would be even cooler with a Horsey badge. | ||

Now imagine that 160lb engine in a 16xxlb Lotus Elise  | ||

It is very cool. Makes you wish Ferrari would make really lightweight street/track car, keep it small, use lots of carbon fiber and drop in an engine like that. That article on the Bristol Fighter was very interesting. It's a little hard for me to decide on the looks from the mag pics but it looks like a awesome car. I tried finding some info on Ferrari engine weights a few weeks ago and came up empty. Did a few searches here but just came up with lots of false positives. If nothing else I bet Jim G could give us the weight of his P4 engine. Isn't L Wayne supposed to know all this stuff? | ||

Mark, Now that's a neat concept. I'm surprised no one else has chimed in - boring question? Or has this been covered before? | ||

Sorry this is not a Ferrari engine but it is pretty interesting. It is made by HS Performance Products which is in the UK. Basically they put two Yamaha blocks on a custom crankcase to make a very compact 2 litre, 4 cam, 40 valve V-8. It only weighs 160 lbs and puts out 320HP.  | ||

I posted this question under the other Viper thread and I'm curious to know the answer. "Vipers have never been my cup of tea. Their volumetric efficiency has never impressed me (among other things). However I was interested to read in the July 2003 issue of EVO that Bristol's Fighter uses the Viper V10 engine. One of this engine's attractive features is its specific output per pound. Apparently it manages 1bhp for each 1lb. And only the Ferrari Enzo betters this according to Bristol. Does anyone know how other Ferrari engines measure up in this area?" |
