There it is.... More than 100 HP per liter on pump gas, as a street engine!
280+ hours of my life. 50+ hours of Brents life and lord knows how much of Len's time was devoted to the conception of this beast!
The results were worth all the time we all spent on the project, undoubtedly. The engine is by far the smoothest running TIV I have ever designed and assembled!
The RPM range is astounding, the throttle response so crisp that it absolutely astounds me. From any RPM a blip of the throttle and a second later the tach bounces off of 8,000 RPM! Dynoing the engine is an unreal experience, the power never ends and it pulls so hard from 4K to 8K that its pretty easy to run away if you let your gaurd down for even a second!
The twin plugs make a HUGE difference, with one plug set disabled the engine runs choppy and lumpy, arm the second set of plugs and the engine idles like silk at 600 RPM! Thats not something you'd expect from an engine with 11.7:1 CR, a 318 degree cam and huge ports!
We have learned a lot from this project that will be applied to future engine combinations and cylinder head composition. The engine lived on the dyno for over a solid week, we performed more tests than we ever have on any customer's engine before- all while taking special care to log every movement of the beast to the degree.
I feel like a 500 pound Anvil has been lifted from my chest. Now it's time to get this baby all detailed and in the crate heading for London!
I can't wait to take this baby for my two laps around Lemans- Lookout France, the Mighty Spyder is coming for a visit!!!
This was a good day on the dyno-

Awsome motor! A serious acheivment. Any chance of a recap of the engines make up? Valve sizes, engine stroke and bore?
