This one looks a little odd.
That's because someone squeezed it into an Elva Sports Racing chassis that used to run with a Lotus twin cam engine.

What carbs are those?

I have never seen such large secondaries/velocity stacks whatever those are.

Care to share any other engine specs? (IMG:style_emoticons/default/pray.gif) (IMG:style_emoticons/default/pray.gif)

I would love to know what it takes to get 200 HP out of a 2L type IV.

I was commenting on another thread recently with Jake about breaking the 100 hp/L mark, and I didnt think it could be done with a type IV.
Greater than 200hp in a type IV, sure, but I assumed huge displacement.

Its actually easier to reach 100HP/ liter with a smaller T4 engine. I've built several 200HP 2 liter engines in the past. They are absolutely worthless below 5,000 RPM, though.

I have a 71X95 now that makes 200HP, I just need to get it on the dyno and decide what to do with it.

This is the difference from what I have touched.
I had a car that could not get on the trailer until well over 5k revs...

so, while it may make lots of HP, its not drivable in normal situations.

Which is why horsepower is, and always has been, overrated.
