We retained the stock Saginaw power-steering pump on our Nova. This required installing the optional Vortech power-steering pulley and hardware kit.
Dyno Time
With the Nova's normally aspirated engine configuration, the dyno recorded 240 horses to the rear wheels. By adding the Vortech Carbureted Centrifugal Supercharger Kit we gained a tire-smoking 115 horses at the rear wheels. | | w/o Supercharger | w/ supercharger | | RPM | FT LB | HP | RPM | FT LB | HP | | 2,900 | 149 | 82 | 2,900 | 188 | 103 | | 3,000 | 168 | 96 | 3,000 | 175 | 100 | | 3,100 | 163 | 96 | 3,100 | 178 | 105 | | 3,200 | 169 | 103 | 3,200 | 183 | 112 | | 3,300 | 177 | 111 | 3,300 | 194 | 124 | | 3,400 | 187 | 120 | 3,400 | 210 | 139 | | 3,500 | 211 | 142 | 3,500 | 221 | 148 | | 3,600 | 223 | 152 | 3,600 | 232 | 160 | | 3,700 | 245 | 173 | 3,700 | 252 | 178 | | 3,800 | 239 | 173 | 3,800 | 269 | 194 | | 3,900 | 243 | 181 | 3,900 | 285 | 213 | | 4,000 | 243 | 185 | 4,000 | 253 | 191 | | 4,100 | 242 | 189 | 4,100 | 290 | 228 | | 4,200 | 239 | 191 | 4,200 | 305 | 244 | | 4,300 | 238 | 195 | 4,300 | 320 | 262 | | 4,400 | 240 | 200 | 4,400 | 323 | 271 | | 4,500 | 241 | 206 | 4,500 | 326 | 280 | | 4,600 | 242 | 213 | 4,600 | 326 | 286 | | 4,700 | 245 | 219 | 4,700 | 324 | 290 | | 4,800 | 245 | 224 | 4,800 | 324 | 296 | | 4,900 | 243 | 227 | 4,900 | 321 | 300 | | 5,000 | 240 | 229 | 5,000 | 323 | 309 | | 5,100 | 240 | 232 | 5,100 | 324 | 315 | | 5,200 | 237 | 235 | 5,200 | 326 | 323 | | 5,300 | 234 | 237 | 5,300 | 326 | 329 | | 5,400 | 233 | 240 | 5,400 | 328 | 337 | | 5,500 | 228 | 239 | 5,500 | 326 | 343 | | 5,600 | 223 | 238 | 5,600 | 324 | 345 | | 5,700 | 217 | 235 | 5,700 | 324 | 355 | | Average | 222 | 185 | Average | 279 | 237 |
