They're on top of a 5.0 Griff engine making 372bhp at the wheels.

Ooo thats nice. I want to add that to my manifold archive - any idea who to credit?

Err i quote "a mad Norwegian " as being the inventor of those!

Pity he closes it in with the plenum top!

Now fit some trumpets and that would look nice under the GT40 rear glass!

Very nicely done, but I doubt 372HP. Esp. at the wheels (even if that number meant anything).

Interesting set-up. Looks cool, but what is the benefit?
It is still a plenum system although with a fancy throttle.
I assume this has not got the benefit of the single throttle per cylinder as it still takes the air from the same plenum?
There must be a benefit in doing it like this, I just fail to see or understand it.

As for 372HP at the wheels, what is the engine spec? It must be something spectacular as most TVR 5 make about 100BHP less than that.

The plenum top doesn't have a butterfly in it so acts just like an airbox and the new throttle plates in each inlet means it now has independent
throttle bodies like the bike ones i had which is the ideal intake setup for n/a engines.

It has individual tb's but I don't see how they can be adjusted to each other. As anybody who has used tb's or multi carbs know if you cant adjust them to each other you can get a very rough tick over and an engine that sounds like an armadillo in a dustbin. This wont effect top power to any great degree but low rpm can be a real problem. Have spent many an hour with vacuum gauges tuning these things on bikes
