16v vs 20v

Postby jondee86 » Thu Apr 29, 2004 9:12 pm

Hmmmmmmm...... in Japan Toyota was getting wasted by Honda in the claimed power for 1600 N/A stakes..... so they had to put something in the shops with bigger numbers. Going 20 valve and VVT was chosen over trying to hotrod the 16 valve, and risk losing the drivability that is essential for the shopping trolley buyer.

My stock TVIS 16 valve is flat in the higher rpm's, while a stock 20 valve has a serious top end rush.... stock for stock there is no comparison !!! Modified will be a different story..... I'd sure like individual throttle bodies :)

Incidentally, 5 valves per cylinder may help the volumetric efficiency on a N/A engine, but 4 valves is more than enough for any forced induction engine.....

Motorsport is like sex. You could take it to track and have a long, enjoyable session, or you could take it to the strip and get it over with in less than 20 seconds.
