Pacemaker PH5014 extractors are engineered for Holden Red Motor 173/186/202 engines running Powerglide automatic transmissions. Designed with a tuned-length layout, these headers improve torque, throttle response and overall exhaust flow for classic Holden street performance.
Pacemaker PH5014 tuned-length extractors are designed for the Holden Red Motor 173, 186 and 202 fitted with Powerglide automatic transmissions. Built in Australia with mandrel bends, precision-cut flanges, and a tuned primary length, these headers deliver improved torque, better throttle response and smoother power delivery. Suitable for everyday driving, street performance and classic Holden restorations.
On average, a Holden 202 Red Motor draws ~3,360 L of air per minute and expels ~10,080 L per minute at 4000 rpm [@600 °C].
On average, a Holden 186 Red Motor draws ~3,094 L of air per minute and expels ~9,282 L per minute at 4000 rpm [@600 °C].
On average, a Holden 173 Red Motor draws ~2,878 L of air per minute and expels ~8,634 L per minute at 4000 rpm [@600 °C].
A great way to install Pacemaker headers without scratching paintwork or the engine bay is to wrap the headers in multiple layers of cling wrap. Trim around the flange area, position the headers, start a few bolts, then cut and remove the remaining wrap before tightening.
