Blitzed Posted September 23, 2022 Share #914 Posted September 23, 2022 Running a air box for two reason, dirt and mainly heat. What you don't see in this pic is the 4" intake tube is now mounted to back side of the front grill. screen filter in the tube at the radiator brace and a 4" inlet turbo waterproof nylon screen at the front end of the tube (grill) ITB horns are beautiful with chrome screens on the ends and look awesome when the box is off but under hood temps can vastly exceed coolant engine temps. My intake air sensor (mounted at the front end of the box) reads constantly half of the coolant temp. 160 coolant temp, 80 air intake. It's not forced air but the air draw at speed from a 4" tube at the grill is cool and abundant. 3 1 Link to comment Share on other sites More sharing options...

On my list to do are the custom stack filters (like singer) and then a belly pan that directs fresh air to the horns. 1 Link to comment Share on other sites More sharing options...

Now if you had dyno time that might be a different story. Low rpms stop to just rolling stumbles a bit. Could be 100 things, but just trying this. My brain thinks it should help low end torque.

Patcon Posted September 24, 2022 Share #918 Posted September 24, 2022 Yes, it should. Smaller bores tend to be torquier which helps off the line. Everything's a compromise ... Link to comment Share on other sites More sharing options...

Blitzed Posted September 28, 2022 Share #922 Posted September 28, 2022 50 is low here (maybe three days out of the year), went EFI to eliminate the choke and the warm up process. What you've really created is a similar cable cruise control from the Datsun Roadsters. 2000's have a knob that pulls and twist locks on the dash for pedal free cruising on highway. Tried it a few times with Roadster, downside the engine heat can stretch the cable so upon disengagement idle speed off the freeway can be very interesting.

On my pedal. It was 41 here this am, soon it will be 20-32 in the am, then warm up to the 50-60s during the day. Then soon it will snow and the z will go to sleep.

duffymahoney Posted January 27, 2023 Author Share #924 Posted January 27, 2023 Something in from Australia! A progressive cam for the overhead bar and my ITB. It would also work with triples. Basically it increases pedal modulation, so this gives you more pedal movement with less throttle blade movement. Should help with street driving and my throttles trying to take huge gulps of air with a tiny amount of pedal travel. Weber kc332 Now machined out to 10mm. Just barely enough room. I had to have the allen bolt turned down. 1 Link to comment Share on other sites More sharing options...
