Greetings. I have a 87 convertible road race street Fox. N/A 444 rwhp, sticky NT01's 255/40 and 315/35 s
Installed a Flaming River 20:1 manual rack, along with a 12" Momo wheel when I first built the car. Run about 5 hard HPDEs per year.
The manual rack is awesome for feedback and cleanliness in the engine compartment. Yes, it is way harder to turn at slow speeds - it is also IMPOSSIBLE to turn in
quickly enough on the road course with sticky tires; certainly not for more than one lap at a time. Physical workout? totally!
Fun ? Absolutely.
Fast and consistent? Not a chance.
Took Jack Hiddley from MM 3 yrs to talk me into re-installing power steering, but now have the full MM catalog in the car, incl extended wheelbase, widened tracks, engine set back 1" and running 18x10's with Hoosier/Conti full slicks front and back.
Jack told me with 7* caster I wouldn't be able to turn the car at all, lol
Can't wait to finish putting it all together this summer, car is currently in a million pcs.
If you are only going to run once or twice a season on the roadcourse, you can get away with it. If I was doing it again, I would do 15:1 ratio, but it would be even more work and an absolute pain in the balls backing up etc.
Here's one of my bud and son chasing me in his 700rwhp GT500 on full slicks, I'm on street tires there, still with stock suspension architecture, MM Koni coilovers and control arms, cc plates.
Starts app 5:00 into this:
And just for fun - a drag race lol:
Here is a vid chasing down a new S550 at my fave track - Mosport DDT near Toronto, Canada
Notice the understeer - that is usually inability to turn in quick enough, or for setting up for the next corner - no way can you control the car to the degree or precision needed without power steering.
Usually soaked from the workout after 10 laps at 70 ambient temps.
Look like I came out of the shower when it's 90 and humid lol
Most people would say it's impossible to the drive the car in anger for any length of time. Had a couple of agricultural experiences due to being too tired to turn the wheel hard enough and just hop the curbs and come back on.......insane and fun.
Can't wait to see how much faster it will be. We figure 3-4 sec on both of the road courses shown; a big part of that because of the power steering.
Hoping to run away from that pesky Shelby as well as an older Viper in our club.
