Air vs Electric stops

[Henry S]

Adger,
Here is my take on the pro's and con's for inline vs. under the carb type stops.
the pro's for inline is:
1. no power loss from adding another set of butterflies i.e. (restriction)
2. adjustability of opening and closing rates to control wheel spin etc.
3. greater adjustability of stop rpm, typically can go lower rpm with an inline vs an undercarb stop
4. hood clearance
5. gets an accelerator pump shot when opening
cons,s of inline
1. carb linkage very important for consistency
2. Air fuel ratio's change while on the stop more than on undercarb type stop
3. carb primary and secondary linkage type important 1.1 vs progressive
pro's for an undercarb stop
1. ease of use electrically
2. air/fuel ratio tends to stay more consistent throughout run.
3. if electric no variance due to bottle pressure and opening closing rates not changing
con's of undercarb
1. hood clearance may become an issue
2. some power loss
3. fuel puddling on the stop blades, can cause inconsistencies.

I have run both types and have won with both types. it usuallly is a matter of preference. a Great resource is to call #1 stops 319-277-5290(Gary) he has a wealth of good information.
As for systems go, you can't beat crewchief pro for prediction software along with altalabs weather stations
