What you see here is the next generation of our kick ass version of the 2316cc Type IV powerplant. Shown below are pictures of the 2316 engine, featuring the "hybrid annihilator" head, also shown below.

This engine was developed by RAT for the Porsche 914 and since its introduction has proven to be a True Performer in many applications other than just the 914.

The original “Annihilator” was driven hard for a few thousand miles and some track events after its two week dyno session where it proved its potential and told us the settings that it needed for particular power outputs. (Yes, the engine can talk- You just have to understand its language)

The original “Annihilator” was an incredible engine but this year I decided to pull the 914 off the road and update it with some new developments, tricks and treatments. This biggest addition to this engine is its “Hybrid Heads” (hence the name “Hybrid Annihilator”). These heads started as a 2.0 Vanagon Type IV head with square exhaust ports. Since we feel thee ports have tremendous potential compared to the original VW port used on the earlier busses and 914s we used new flow data to optimize the “Hybrid heads”

These heads incorporate all the best changes made by VW/Porsche from ALL Type 4 heads used over the years and have been outfitted with a special chamber shape. These heads also incorporate our newest Ultra light valve technology with 7mm stemmed valves, super light chromoly retainers and dual springs. These have been designed solely by Len Hoffman of Hoffman Automotive Machine for these and upcoming other versions of the hybrid heads. The features of the “Hybrid Head” are:

• Specially shaped chambers
• 2.0 Square port exhaust ports
• 76% flow margins from intake/exhaust port
• *** Spark plug holes reduced from 14mm to 12mm and relocated to the 2.0 914 Porsche location***
• 7mm Ultra Light valve train
• All valves were DLC coated for superior friction reduction (DLC coatings)
• All rocker shafts DLC coated for friction reduction
• Heads were welded and machined to replicate the 2.0 Porsche intake bolt pattern and intake port angles

Len has done an excellent job on this first pair of “Hybrid Heads” and we are looking forward to surpassing the 181 BHP that this engine made in its previous state by 10% with the developments incorporated into these heads!

We now have an effective means of reproducing the famed 2.0 Porsche head that is getting very hard to find and expensive. This can be done with Oval port castings, or the “Hybrid” castings. Thanks to Len for all his exceptional hard work and his contribution of his time to my R&D program that is taking the Type IV engine far into the 21^st century!

Look for dyno results from this engine soon as we plan to test it in February and debut it at the Southeast Dyno Day in March to awe the crowd!
