Our engine could use a lightweight flywheel and we selected a McLeod Tuner Series Aluminum flywheel part number 565004 to complement our engine. The flywheel weighs about 9 lbs and is machined from 6061 T6 aluminum with a 1045 hardened steel ring gear bolted in place.
The McLeod flywheels has a replaceable steel friction face and is SFI approved for safety certification. The flywheel saves about 14 lbs of rotating weight and will free up a lot of horsepower that is wasted trying to accelerate the heavy iron stock flywheel.
We used a McLeod Street Elite clutch part number 762061 for our engine. It is recommended for engines with 50-70% more than stock, about what our new engine should be doing. The clutch kit comes with a new pilot bushing, a throwout bearing and a clutch alignment tool.
The Street Elite disc uses a carbon/organic friction material bonded and riveted to a steel backing for improved heat resistance and burst strength over the stock disc. It has a marcel spring to help smooth engagement and a sprung hub to reduce driveline shock. These features make for a disc that can take more power than stock while still being very smooth in day to day driving.
The McLeod Street Elite pressure plate has a much higher clamping force than stock but a good leverage ratio for the diaphragm spring so the pedal effort can still stay low. This combination of parts can hold a lot more power than stock and take much more abuse but is still perfectly streetable for daily driving.
Stay tuned in the next edition of Pump Gas K Motor, we will get into the top end, most importantly the heart of any high-performance engine, the head!
