Ok, I have a stock block, heads, cam etc. The lowest setting on the TNT F4 is a 200 shot, do you think with the stand alone fuel system I have (run C16 in it) I would be able to spray the motor on the 200 shot and be ok? I always heard "don't go above 150 blah blah" but with DP and a SAFS would it work out? Anyone done this?
thanks

i run 175 on the wife's car and 200 on my 00 formula. the 00 formula has a single nozzle in front of TB. been doing it for almost a year now. the fuel system is completely stock. and i run stock timing with no retard. for you with a separate dedicated fuel system, i see no problems at all. the motor in the 00 formula is all stock. i do run champion RC9YC (2 steps colder than stock) gapped to .035". and i run plenty of 11s with both cars.

i don't think a supercharger would get a stock motor into the 10s either.

Thanks for the info, I do plan on running much colder plugs and getting it tuned for sure, I don't want to mess around with it, just be safe.

Well I spoke with TNT and this kit is really only jetted to go as low as 200 (25n 15f) If I want to spray 150 I'll need smaller fuel noids and then I can jet it lower. So i guess I could do it, just need smaller noids, dont know how much those run tho.

When you get the rest of supporting basic bolt ons we should linem up.

To answer your question, our nozzles systems were orginally designed with a 300-600+ range.. So the fuel sol is way to large to be turned down that low, and the fact that the smallest jet we offer is a 15 so he would have to change his setup.. We are going to offer a nozzle system here in the near future that is geared for the lower hp settings..

Well first off our nozzles are designed to flow up to 350hp of nitrous and fuel so it dosent control the fuel as well at 15hp..When James first started this deal he never would have thought people would want to go lower instead of going higher.. Second our smallest fuel jet is a .015 so that x 8 with a .250 fuel sol makes it very hard to acheive less 25hp on our nozzle system.. The smaller fuel sol wont allow it to be turned down much more but it will help.. As far as volume goes, this seems to be the debate of TNT systems.. Our .093 sol with a #4 line and 2 x .046 jets = our 150hp setting, now from what I just read our 150 setting on our F2 with .125 sol a #6 line and 2 x .042 jets = "235 hp" so I guess our math is off or we have demonic nitrous kits

Yeah I agree David, your math sucks.
our nozzles systems were orginally designed with a 300-600+ range..
then
our nozzles are designed to flow up to 350hp of nitrous and fuel
I'm not saying I dont renig playing spades or hearts (or Go Fish) but damn, back to back your getting called out!
Now, lets talk about one particular kit, a direct port kit (seems like your mixing your DP and Nozzles or something). The size of the solenoid should only be a factor if your trying to jet over the amount of solenoid capacity. So lets say your .250 orfice fuel noid should be capable of flowing up to 600hp shot size of fuel on EFI Pressure (since it does matter what the FP is as well). If your jet size of .015 (what number jet is this? Like NX would just simply call it a 15 not a .015???) on a DP kit makes 300hp, it wont change because of the Noid size. So you swap noids to a .125 orfice (we'll say good for up to 300hp shot) you would then have a max jet size of .015 on the fuel since it would total 300hp once combined with nitrous, and in that respect if you went to the smaller .098 orfice fuel noid, youd only be flowing what the noid allowed, which would be under the 300shot size.
I would rather have a solenoid too large then too small. It ensures there will be sufficient supply waiting, unlike the 5177 where ppl remove the jet and run it seeing average 140hp dry shot, thats all the orfice of the noid can flow and or nozzle. I would think your nozzles can flow quiet well and the restricition would be the solenoid, but not sure since your numbers dont jive bw your two posts above.
If your jets are not propietary then it would be easy to get whatever shot size you wanted, simply convert over to the logical jet sizing in numeric order and use smaller jets.
Of course I am using math thats good enough for me to understand, and government work so feel to slap me around like a 10# bag of welfare beans if my post doesnt make sense.
