Throttle Stop Question

navamotorsports · 07-20-2011, 08:32 AM

Has anyone made a home made throttle stop and can you post pictures or possibly give share the idea as to how to make one. I know I can purchase either an electric or an air throttle stop. My car is running really tight I believe the best it has run has been a 10.75 and I would like to race in the Hot Rod class in San Antonio, Tx come September any help would be appreciated. Thank You.

At your ET I think I'd just do it with weight....

I agree with Bob, weight is simpler and more predictable when your that close to the index.
I have a home made, inline air (Co2) cylinder stop and it's a pain in the *** because there are a lot of variables stroke length, stroke time, the amount of resistance,in the carb linkage, Co2 Pressure, how solid the throttle pedal stop is, how much stretch and slack in in the throttle cable.
Ballast is the simplest and cheapest but there a couple of other ways too, Moroso markets a fixed stop and there's some guys selling a restrictor plate system which would work too also if you using a vacumn secondary holley or demon you can put a stop on the vacumn motor.
But if your determined to build you own in line stop contact me and I will help you with it.( But I can almost guarantee you, at some point, it will drive you nuts!)

Years ago I made a bracket that bolted to the back carb bolt, I then took a cariage bolt ground the end flat and ran it through the brack with a jam nut on both sides. The carb linkage would hit the bolt keeping it from opening all the way. It was good for about 2 tenths in the 1/8th mile.

I think Moroso made something similar for a while. Don't know if they still do.

MOR-65042 is the part# about $27.00 retail

I have made a couple for dominators and have slowed my car up as much as 5 tenths. A couple of buddies are using the EZPLATE system to slow their cars up. Its a little pricey but, evidently very adjustable.
