Dyno results - Tquad vs Holley vs Qjet - tuning issue, too rich
Just referring back to my post 104. I remembered later about an issue I had with the brass restriction. 9000 series 800 TQs were used here on 302 & 351 Ferds. Many people [ idiots ] replaced them with Holleys or clones. The TQs were jetted incredibly lean & enlarging the jets would have made a huge improvement. The Hs were performance jetted & of course performed better. One owner bought a Falcon with the H on it but couldn't stand [a] the lousy economy & burning his eyes in the garage after 5 min of idling. So a rebuilt TQ replaced the H. I did not rebuild the TQ. Performance was lacklustre, not much power when the secs opened. I was asked to assess the TQ. It had the above mentioned brass tube restriction, which was delaying AV opening. I drilled out the restriction & did a couple of other tweaks. Engine now pulls hard & smooth at WOT[ for a 351 ].
