Yea I am sure some people have had success with one and I won races with one myself , but overall a plate stop is a better choice.....

I tried various inline stops, changed cables, adjusted everything and looked for variations many times......different fuels......all the same result......occasional runs not where they should be and usually at the worst time.

I switched to a Plate stop.......2 different models......air operated.......and none of those issues.

I also am running more MPH than ever and using a plate....and on Sunoco Red or any other std fuel.....like X-16

Inline stop is good for bracket racing.....starting line control.....

I had both on my car at one time and could switch back and forth.

Took inline off and threw it in a Box..... A Plate stop for the win.....LOL

Couldn't agree more, Rich. I use an inline stop with mechanical injection as you used to do. If I bring it all the way back to idle on the stop, it is good. I've tried carrying some RPM down the track, and it is all over the place.

The plate stop under the carb on my door car is very good.

I would gladly give up 20 hp for the stability a plate stop brings.

All good info, Rich, and I'm sure that a plate stop would be more consistent because of variables involved.. however, when I installed the #1 Stop on my combination, I lost 3 mph.. I've been told that this is a common occurrence.. you're the first to tell me that you picked up..

I plan to do more bracket racing than .90 racing, and decided to switch back.. and not to mention that a recent manifold change, to the one YOU suggested that is supposed to be 3 mph better than what I had, left me with not enough clearance to put the plate stop back on.. but I did just learn that Sun Coast has another hood for my 27 Roadster, with a taller scoop... and Edelbrock does agree with you, as do many others.. THNX RICH!!

I'm only planning on 4 Divisionals this season, and only 1 National, as I have a credit from last season.. otherwise, you would not see me at a National Event...just sayin'...

Charlie it always takes trial and error on this stuff for sure as you know.

I did not pick up MPH just from changing stop styles.......The intake change for me was the gain....and I don't think I a plate slowed me down much.

My best MPH in stop racing was with injection and an inline stop....Virtually NO loss of MPH

A dragster obviously is very easy to swap intakes, spacers, stops with no hood issues......

Pretty much anyone you talk with has varying results with different equipment.....

If I was crossing back and forth from .90 to bracket racing I would probably run a Ron's Terminator as I have in the past and work on a better .90 setup....

Have fun wherever you race .....why else do it....LOL

You're right, Rich, and hopefully I will have the results that I have figured on.. I've talked to several people about the manifold, and have received the same results that you provided, so I think that will be a MPH plus, along with the inline stop, that should return the 2 or 3 that I originally lost... BUT, this stuff is all in my head.. we'll see what it actually does at MG this weekend.. hope to run into you soon...

Charlie I will be there tomorrow afternoon probably.

Usually parked along the tree line in the lower 40 or somewhere down that area.

Weather looks good and it's still one of the best places to spend a few days at for a race.
