Jetting ?????

[DL]

and a good way to check ur plugs is have somebody pull u back to the pits idlen back always looks like ur running fat on fuel if ur running a colder plug on nos just a thought good luck

I try that next weekend thanks .I havent had a chance to go to the track in week or so . I did hit that shot on a back road and it felt a lot stronger . Ill see if it any beter at the track

[eldabo]

I had a chance to run it last night with 88/88 and it only picked up1 100th of a second and 2 mph seem like it was just like yall said rich ass hell .
I trying to deside weath to keep the same fuel jet and go up on the no2 or go smaller fuel. The car ran great no prob with the set up now im just wandering if and how much im leaving on the table.

What did the plugs look like?

[eldabo]

They looked good a little grayish but clean no specks no fouls.

[eldabo]

So John what do you think ? Bigger on no2 or smaller on the fuel? Any is welcome to weigh in on this .

Thanks

Lean is fast, up to a point...

1/100th of a second? .01 seconds? You should have picked up more than that on a 50 shot. Something does sound strange. Hell, I'm happy with mine if it repeats within a hundreth of a second on motor alone. Are you sure it was spraying at all? Or did it spray and then cut out? How much timing are you pulling out of it for the spray? I would worry why I only picked up .01 and 2 mph before I worried about what size jets to go with next!!

Keep us posted.

Might clarify how much it picked up, if it was only 2 mph on that big of a shot, somethin's wrong. Is that over your other smaller shot or over motor only? To lean it out you can lower the fuel pressure (where are you now?) or increase the nitrous jet or put a smaller fuel jet in it. How much total timing (with retards) are you using when spraying?

[eldabo]

Well I was running sniper system it has very small silinods and they were maxed out at i think 175 hp shot . I tryed to get a little more out that system by taking a hobbie drill and opening the jets out but that was no help. I bought the cheater silinoids and upped the jet sizes to were they are now. Im running 5.5 to 6 psi on the fuel flowing. It is dead headed now .My brother said it put out a cloud of black smoke when I took off. Oh im pulling out 8 degrees with a retard box .

For a 150 shot, using NOS jets, it should be a .082 Nitrous jet, a .071 Fuel jet, and 5.5 psi fuel pressure. (IMO) If deadheading the regulator, I pull the plate and set the pressure with the fuel spraying in a bucket through the plate. That way you have the correct fuel pressure when you pull the trigger...

[eldabo]

Yeah Ill do that tomorrow .Did you build you truck or buy it? The reason I ask is there used to be one running around in Mobile Alabama that was just like yours.

[John_Heard]

So it was 2 mph faster than the 175 shot system right?

[eldabo]

Allmost it was 96.75 to a 99.08 and the same 60ft. I would like to test tonight Im just trying to deside the right way to go with the jets.
