how can i make my 60 foot times better i have ice man upper and lowers controll arms a wildrides anti roll with drag radail and 456 gears i have tried everything i know and no inprovement please help me
Just one piece of the puzzle is to know at what rpm peak torque is made by your motor, then get a convertor to stall just below that point for a turbo trans-just above for a 'glide. Another piece is weight transfer. Get weight off of the front of the car and tune the front suspension to allow as much up travel as possible. Relocating the instant center rearward and downward from stock usually helps too.
thats not a correct analogy of picking a converter...... i reused the converter when i built my new 421 and art at coan told me to try it first before he messed with it. it used to stall at 4500. art said with the new dyno numbers 628@6600 and 552@4500 that it would stall at 5500 now.....so i said isnt that too high with the torque peaking at 4500? he said no. he said to look at how much torque it had lost by the time it reached max hp. he said then look at how much hp is gained from peak tq to peak hp... if it gained more hp than tq it lost then he said to leave it he will take hp over tq any day. i was confused by this as well but after crunching the numbers and seeing the data logs im launching at 5500 and dropping back to 5900-6k on the shift and trapping at 68-6900 with the converter slipping about 6%. so there is much more too it than just guessing on a converter but yes it is one of the biggest factors as well as suspension in 60 footing.
There are different theories out there and so there's not one right one and the rest are wrong. The Mustang guys are notorious for launching off the limiter using hp for their motivation rather than torque as the "little" 306's and 347's are kinda' soft in the torque department. If an engine setup is concentrated more toward the top end (race) rather than the midrange (street/strip) then that skews the discussion somewhat. My understanding of the scenario is that one should leave around peak torque, shift a little past peak hp so that the fallback rpm is near peak torque, rinse lather repeat. Torque is what gets ya' moving and hp is what keeps ya' moving. If your torque peak is 4500 and you're launching at 5500 and falling back to 6000 then you're using all hp and not so much torque. The cat gets skinned either way, just differently.
