Flat 6 Innovations has the only M96 specific engine Balancing program available in the USA.

Any engine can, will and should benefit from dynamic balancing!! WE ONLY BALANCE Porsche M96 ENGINES!!!!! Not Hondas or Harleys!


There is absolutely nothing on the planet as good as a free revving, well balanced engine, it keeps wear to a minimum, and helps keep fasteners and complete engines together over a much longer period of time. One gram (the weight of a paperclip) may not seem like much static, in your hand, but put it in motion, and give it some radius and you'll be amazed at what it can weigh. An out of balance engine can consume parts like a shredder, and can even break exhaust flanges, intake manifolds and engine mounts by sending harmonics throughout the vehicle, that can even be felt in the drivers seat!


Our CNC dynamic balancer accurately balances complete rotating assemblies to within .2 ounce inches, which is the standard for Indy, CART, and NASCAR engines, turn 9,000RPM for hours. The CNC addition allows us to print a "Bobweight card" for the entire engine which displays the amount of dynamic balance both before and after the balancing is completed (it can be hundred of pounds different) and it illustrates the weight of each individual part, and shows connecting rod weights in, overall, big end, and small end and even the weight of rings, wrist pins, retainers and etc. Our engine reconstructions benefit from having the engine balanced to our "Race spec" or "Intermediate spec" set of tolerances as standard. EVERY ENGINE WE BUILD IS BALANCED, even stock!!


For customers that have their own engine parts, we also offer this service to you, even though we are not assembling your engine. You will still receive the dynamic balance and bob weight cards, and have a choice of 3 levels of balance tolerance:



"Performance" This spec is for basically stock engines, or for those who want a balance job that will keep their engine from "self consumption".

This is recommended for every engine, even bone stock! The dynamic tolerances are set to .7 oz in. Connecting rods are balanced overall to within 1 gram (not end for end) and pistons are balanced to within 1.5 gram. Budget $570.00 for this service and allow a 14 day turnaround according to our work load.



"Intermediate" This is the most used tolerance; it allows for a well balanced engine, is affordable and provides balance good enough for a sustained 6,000 RPM engine. Dynamic Balance tolerances are set to .5 oz in and Connecting rods are weighed end to end to within .05 gram, and pistons to within .75 gram This is the most typical state of balance. Budget $850.00 for this balance job, and allow a 14 day turnaround time.





"RACE" Our RACE balance is unlike anyone in the business, mostly due to the fact that no other shop in the aircooled industry has a balancer that parallels ours! Our RACE balance is good for 6500-9000 RPM engines . This is the highest state of balance we offer and we maximize the equipment with tolerances of .2 Oz In This balance we take everything to the extremes, Connecting rods are balanced to .1 gram end for end per set of 4, and pistons to within .1 gram per set of 4. This balance takes a lot more time than any other tolerance and is not a flat rate service. Plan on spending $975.00 for this balance service, turnaround time is 2-3 weeks.





Here is a list of what we need from you:




Pressure plate

Front crank pulley

Connecting rods

Pistons& pins

Piston rings

Some customers write to ask us if we can “Balance their crank”- that’s worthless! We have found that most imbalances come from the other parts of the engine, especially flywheels and pressure plates. IT ALL MUST BE BALANCED AND INDEXED! We only do only complete assembliesWith any state of balance, you receive the balance sheets and ALL PARTS ARE INDEXED and stamped for proper assembly! We even balance and index clutch bolts for reassembly! Balanced assemblies that are not indexed for reassembly as they were on the balancer are worthless!
