On PULP ??? even with the booster ??? it was pinging too much, so a Jap-spec EF Honda Civic was used with a 1.6-litre VTEC and about 10.0:1 comp ratio.The graphs tell the story though, and to be fair to the products, with variables such as heat soak, the results weren???t as conclusive as could be gained from an engine dyno.
