:reddevil i get the honor of testing this bad boy out tomorrow nite. i cant wait for this goodie.
on a side note, i gave the car a test run on one of the local backroads early yesterday morning. the holley was running fairly well considering its not tuned. i managed to pull over 100 mph at the end of the 1/4 mile. (we have the road marked off) :jester
I also need to tune the carb on my motor also. I just get so excitied I slap it on a run around for a little while. I just put a 650 DP from Demon on my zz4 oh I love mechanical secondaries. Now if it would just stop storming after I get off of work.
I absolutely love my Speed Demon 650 with mechanical secondaries. Starts right up (with no choke!), idles great, responds great. Right out of the box. Nice carb. :yesnod:
i got the 625 cfm road demon, with vaccum secondaries and electric choke.. i figured that was my best bet with the smaller small block that i have :crazy:
anyone have any problems with it losing tune? and how much power did it give you if any?
I too have the Road Demon. No troubles with it losing tune but I haven't had it for years. It did a wonderful job with my L-48 and I suspect it would do a great job with an L-82 but it is too small for the ZZ4. Can't tell you the number of times I thought I had a gas leak when I came to a stop and exhaust fumes wafted forward. :rolleyes: Don't seem to see any black smoke but you sure can smell it. It's not too bad. Idles nicely and has great throttle response. Even seems to have a good bit of get up and go.
I plan on snagging the Speed Demon calibrated for the ZZ4. Hopefully I'll be able to sell the Road Demon because it really is a great carb. Had planned on my next setup being EFI but I'm beginning to wonder if I'll ever get to that. :lol:
Demon sells a 650 mech sec. that is set up for the ZZ4 (demon #1282010CZZ4). http://www.sdpc2000.com/cart.asp?act...art&catid=1922 There is a link to a chevy place that sells them. I ordered mine through summit racing last month. I still need to fine tune it, but man this thing runs.
