Rons 1060 Terminator

[onedragracer]

Need some jetting advise. Is anyone running a 1060 rons terminator on a 468. I currently have 33 jets in the nozzles and a 90 pill in the barrel valve. I'm still too rich. The motor has a slight bog and slow coming up on the converter. I changed the pill to 94 and it hits the converter alot faster. A couple of racers in my area are running the same setup with alot bigger motors and are running 38 to 39 jets in the nozzles and 70 to 75 pill in the barrel valve. I just need some sort of equal comparison.

Whats the leak on the barrel valve? I'd think 33 and 90 would be lean.

26% on the barrel valve, I've rechecked it several times. The butterflies are set at .008. The pump is a 0-0.5 and the complete setup came off a 565 that ran 7.54 in Dallas last year. I'm beginning to think this pump flows way too much for my motor. The pump gear is a 36 and the crank gear is 18.

0 1/2 pump should work fine, how good of a 468 we talking ?
do you have a egt if so whats idle egt ?

If you have a primer plus can you make it fat and see if it comes up faster on conv with just gas ?

I too think the nozzles are too small, i run 32's with a 0-1/2 on a 377" bowl with .085/.095 depending on the weather, my friend runs #35 nozzles with a bowl and 421" with .070/.075. I'm thinking you need atleast 35's/37's with a 468" motor.
I run 22% leakdown with the blade set at .005, we don't run a hi-speed bypass.

David this is the car I called you about. He had 38 and 90s and wouldn't go but to 3800rpm on the converter unless he went up on wot real slow, then it would go to 5800. James Monroe said he thought 35s might help. He didn't have any 35s so he tried 33s. He also removed the check valve and no help. Air here at 6500 to 7000. With the 33s and 90s he said its still sluggish going up on converter, but better than the 38s. 468 probably should be around 700hp, give or take 50hp. I'm not for sure but isn't an 0-.5 for 750 hp and up and a 0 pump for 750 hp and down?

I thought it may be the same setup. I'd of bet a 100 bucks it was the check valve. Like I said above this thing should want 35/80-90 pill for sure. I used to run the 0 1/2 pump on a sb that might of made 650 and had no issue. Did you guys check and make sure the pulleys are right, meaning its not over driving the pump ?

No egt I assume ?

[dparker]

I was sure hoping taking out check ball would fix it also. He doesn't have an EGT yet. and has 18/36 on the pulleys. Sure is acting like to much pump though. James is going to put the return line in a 5 gal fuel can this evening to check the return, just to make sure there's not a problem there. Our air this time a year is 7000ft. Maybe James Monroe will answer his phone today. Just hoping you had another fix in you bag of tricks.
Hammer/Flex the cat.lol.

What color is the barrel valve gray ?

I wish I had a small pump i'd send it to ya just to rule it out. I also tried calling Monroe this AM ... ring ring ring and voicemail is all I get. :evil:

[onedragracer]

David the barrel valve is purple. No high speed lean out yet, I have it just haven't installed it yet. I'm gonna put 36 jets in the nozzles tonight and jet the barrel valve from there and see what happens.

[hammertime]

Let me know how it goes, I did see a "0" pump on rj if you think thats the fix, but I think its something else. Have you ran with this converter before ?

[onedragracer]

Not with this converter. I talked to James Monroe this morning and I went over everything I have checked and done. He said that I have covered all the basics. I'm gonna take out my 7al3 box tonight and put in a spare 7a box to see what happens.

[hammertime]

He didnt think it was the pump did he ?

[onedragracer]

James did suggest the pump could be flowing too much, but the MSD box change will tell if its fuel or spark related. The car never really ran what I thought it should run. Maybe I have a weak ignition problem but running VP113 it wouldn't show up. Now switching to alcohol with alot more fuel volume a weak ignition might not keep up. The engine doesn't bang or pop just really sluggish coming up on the converter. The best E.T. with a carburetor was 8.89 @149. Should be running 8.45 to 8.50 @ 155.

Follow up on my 1060 terminator system. After several weeks of checking everything possible with the fuel system, my problem turned out to be a converter that was too tight. I had the converter loosen up to 6150 and it works like a champ. Second weekend out I won the Electronics race at one of our local tracks. 5.19@132mph in 5700 DA. Not too bad for a 468!

[hammertime]

great job !
thanks for letting us know what it was, I been wondering :D

Hard to beat a good 468 for the money to build them, what weight car is yours ?

[onedragracer]

I don't no what the weight is yet David, I haven't been on scales yet but I definately like the car now. First dragster, always had door cars, but I will never go back. I think it has alittle more in it with some more tuning. Ordered a EGT today to help. But for now I have a 85 pill in the barrel valve and 38 jets in the nozzles with 28% leakdown. Leaves hard and pulls like a SOB in high gear. 1.16 60ft.
