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.

That used to be the rig my Volksair compressor was mounted on.

Did that motor come out of a Royale RP4? A vintage race friend restored a Royale RP4 that had a 2 liter 914 engine. I had it in my shop about 10 years ago and then he sold it to a fellow in Connecticut. My friend had Hank Clarkson build the engine. It dynoed at 200 HP and 175 lb-ft of torque.

What carbs are those?

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

The engine is a 95 x 71 2 liter putting out around 200 HP.

The headers supplied by the owner don't fit on my test stand.
We're not dynoing it, only proving to the owner that it's healthy.
When it came to us the crank was seized, which turned out to be from a bent crankshaft.

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.

Very cool motor!

I would guess lots of RPMs...that's how my Honda race engine does it (sans "torque").

Chris is building an engine for my ex-ITA 914; I'm expecting at least that much (IMG:style_emoticons/default/wink.gif) (no, not really)...

A 95mm bore is a bit of an odd size. What can you tell us about the pistons & cylinders?

Race motors have been doing it for years. The FP guys were running 1.8 liter motors making anything from 160HP to just about 200 HP, depending on if they wanted to refresh the motor every season, or every weekend. There are no mysteries to it--they have high compression, rev high, have reduced parasitic losses, and lots and lots of money in the heads.

The mystery is how you get 100 hp/L out of a streetable engine that lasts a good long time.

Aren't those the kind of cast aluminum valve covers that everyone says not to use? (IMG:style_emoticons/default/idea.gif)

I have a pair that I've never tried. (IMG:style_emoticons/default/laugh.gif)

These are real Claude's Buggies valve covers with their custom gaskets.
They're a better quality than the other cast covers I've worked with.

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.
