Re: Throttle Stop w/ 1 blade TB / roll RPM Q
Quote:
I'm NA, but in both my S/ST and SC car I come off the stop in Low and shift downtrack on RPM. I lose little to no MPH doing this, and especially in SC I will out-MPH cars that have 200+ more horsepower than I do. It takes a lot of power and time to get the car moving in High gear. Again, if I had a supercharged small tire car I'd be shifting on the stop, but it will cost you some MPH.

Disagree that with stop RPM and stop ON time being equal, a car coming off the stop in High gear will have more MPH than the same car coming off the stop in Low, even with the Low gear setup having a longer stop duration and going WOT further down the track.

A blade stop will not work with EFI for same reason it won't work with Enderle/Rons injection. You can restrict the airflow all you want, but the barrel valve or ECU TPS will still see WOT and be dumping fuel in. Just for my 2¢ , I agree (especially in my case of being on the heavy side for factory interior; essentially super stock trim) that coming on the stop in high gear will control wheel speed but lose MPH and possible consistency from the motor lugging from basically a 20-30 MPH roll in high gear. On the other hand, coming off the stop in low gear may yield a traction limited situation depending on how the boost curve comes in. I'd like to think that even at 9" wide, a 30" tire with a powerglide and 3.89 gear would be pretty damn hard to spin coming off the stop in low gear. But again, depends on the boost curve. |

Re: Throttle Stop w/ 1 blade TB / roll RPM Q
Thanks for the reply. Like you, I’m looking at how to adapt a rod to the single blade TB. I could use a 4150 and an elbow, but I’d prefer not.
And as for forcing the blade closed if it hangs open, I have an interior battery cutoff that will kill everything mounted to my shifter. Last edited by C5 Pete; 12-29-2017 at 10:35 PM. |

Re: Throttle Stop w/ 1 blade TB / roll RPM Q
So, with these adapters, the cable mounts just like a standard cable on throttle body, but the threaded end screws onto the end of the ts shaft?
I was considering welding a rod onto the blade cam of the throttle body to attach the rod, but maybe this cable adapter would work better. |

Re: Throttle Stop w/ 1 blade TB / roll RPM Q
Well, I ordered the 10" cable from Kartek.
I have a TS coming from Biondo, and a cable TB to replace my DBW TB. I will figure out a way to mount this onto the Holley Hi Ram I have on my 427 LSX. I'll report back once I get everything. |

Re: Throttle Stop w/ 1 blade TB / roll RPM Q
For what it's worth, I used a Ron's Terminator on the stop for ONE RUN. I got gassed out by the Methanol, so I put the carburetor with gasoline back on. I ran the Terminator on the stop with a solenoid bleed actuated by the throttle timer, through a 90 pill at 3500 rpm. Worked fine
