Dual 1050 jetting and setup
Im looking to put a couple 1050s i have on a gutsram. Looking at options for linkage -Wiand maybe and a good starting point for jetting. They are both 9375 3 circuit carbs. This is what i have to work with for now.
Will be running on 110 fuel. More for looks than anything , feel like it time to put a tunnel ram on my gasser. Ive been high 9s, looking to tune better and pick up some. 13:1 517, with kre 380 high port heads. Th400 , 6k stall, 4.10 dana 60 with 29.5 10.5w tires. At 3500 lbs |
I flat out can’t see a need for you to run duel 1050s even without knowing how much vacuum your pulling at peak rpm even now with what I assume is just one carb!
A single 1150 Dominator can feed a motor up to 950 hp just to put a number to the conversation. |
I used Enderle linkage.

Just an example: Bill Klausing had a Tri-Power set-up with 3 Holley 650 cfm 2-BBL carbs. Did not want to change carbs. We restricted the airflow thru the carbs by not opening the end carbs completely and the car went quicker. AGAIN: "More for looks than anything" Tom V. |
I think i run 94 or 95 jets now , would I drop to like 85's or something ?

We ran 2 HP 950's and 2 1150 Dominators on a Gutsram. I can get the jetting if you want it. It's in the old log books I am sure. We used a throttle cable and a universal Enderle linkage kit. It had everything needed to make a simple, reliable linkage system. Believe it or not, the 2 1150 Dominators had better idle quality, less, loading-up at idle, and more crisp throttle response than the HP 950's. I was surprised by this and really came to like the Dominators. I expected them to be lazy at low load/speed. They worked great.

Yea , if you can get it thanks. Im curious as to a starting point

I looked over the specs. as delivered on those carbs. I think you are going to be in the ballpark as delivered. I remember on the dyno we messed around with the jetting and air bleeds some and ended up going back to almost stock calibration. We did have it stagger jetted a little to favor cylinder #1 and 2. Cylinder #2 always ran lean with the Gutsram and we did add fuel to 1 and 2. It will take a few days to have Eric look through the old log books.

Our log books had nitrous and fuel jetting for those systems but not the carb jetting. Sorry I don't have that info. Thought I did , but no. I do remember as mentioned we were within 3 sizes or so of the as delivered jetting.

Thanks for checking, i do have an o2 bung for my fenderwell headers and getting a wideband over the winter

I'd personally spend the money on tuning up the HP heads ports and valve job it.
|
Well my compression isn't helping either, when i planned this out 110 was still 5.99 ga, so kept it at flat tops instead of closer to 14:1 where id like it. The valve job is recent, but understand about having these gone thru

Yea, Darby comes to mind. Mines closer to 12.75 actually. I still feel like there is something going on with the heads so I don't disagree with you about having them gone thru.
