VP commos they r quickish!?!? y?

[Beetus]

i dragged my mates vp commodore 5spd manual ute against ,my ed v8. Ive got extractors hi flow cats and filter, hes just changed the mufflers and air filter. I had a very hard time beating him. he ate me off the start and i only reeled him in very slowly but once the quarter was done his front end was at my boot still. Now i looked up the specs on them, and it says the vp commo standard was 0-100 in 8 secs!!!! thats quicker than any other commo till 2004!!! whats the deal with that. is it because they are so light??? btw mines auto.........
