Labratt OP Good Ol Randy B! L Joined: Sep 2009 Posts: 2,325 Clinton Twp... north of Deetro...	FINALLY got a break from truck break-downs,and trying to sell our house! If I didn't use the calculator and average the 4 runs each with these 2 carbs...I wouldn't believe it! Not sure what the DA was at the track(Ubly)yesterday...but it was HOT and humid! When we started running @ 1:15 it was 85 degrees,and 90 degrees on the final run at 5:30. Since there weren't a lot of cars for the T&T session..and my car was running cool...only 170-175* after each 1st run,I hot-lapped it 4 times,for 8 total runs. Never went over 185 degrees all day! *RESULTS* Holley 950HP- Avg. from 4 runs..60' 1.67...E.T..11.53...MPH..116.5 Race Demon RS- 4 run avg.- 60' 1.69...E.T..11.51...MPH..117! I'd definately call it a DRAW! BOTH carbs worked well! I attribute the lousy 60' times to NO starting line prep! Didn't see them spray at all! I would be happy to own either one of these carbs! Thanks to Brad Haak,for the use of the Race Demon...and Russ Dudek,for the use of his Bigs 950HP Holley! 6734545-UBLYTNTWITHGTXANDJERRY-7-16-2011002.jpg (220 downloads)

Didn't change the MPH at all on the Demon. Went from 78 to 82. Went from 80 to 84 on the Holley...picked up 2 mph! Still can't believe how darn close these carbs performed on my car! It was HOT...but felt GREAT to do some SMOKY burn-outs and run the 1/4 again! Since Drag Times has no Ubly listing to figure the DA,I had to take data from Lapeer Dragway..the closest track. The average DA there from 1:00 to 5:30 was 2955. They're saying my corrected times would be 11.23 @ 121. I'll take it! 6734633-GRATIOTCRUISE-2010026.jpg (67 downloads)

It MIGHT take a seasoned pro to eek a 10.XXX out of it but, I think it'll get there with minimal changes. The free or cheap tweaking is gonna net the biggest gains now. Props to the people who have offered their parts and help. I'm sure either carb will work for you, most people are more familiar with the Holley's. You've done well to document all the incrementals and weather.

Randy..ya' got an SV-1 to send to me?...I'll try it out! Zippy...looks like the carb tweaking here at home worked out pretty well!...couldn't get 2 carbs to run pretty much identical numbers like that again!...IMHO! Thanks for the kind words,Sean! When you comin' to Memphis for that "Magical tweak session"??? I honestly don't believe I'll see a 10 second slip until the Eddy's get ported!...hopefully this winter!

How did you get your water temps down in that weather? 72 Dart 470 n/a BB stroker street car `THUMPER`...Check me out on FB Dominic Thumper for videos and lots of carb pics......760-900-3895.....
