75 shot at the track

So after running a 55shot last year (wet) i thought i go to a bigger 75 shot(wet). found at the track that wow there is way to much fuel. i have a wideband and it was reading 10.7,
So tried to reduce more fuel and bring it back to at least 12.5 - 12.7 that range there.
Last year ran a 14.4 on 55 this year i dont think i will break that. Just to much fuel.... lol

i just used the apexi and i raised it to 12.7 all day, i ran a 14.152 @ 102mph, 60ft 2.6s, i had nasty traction issues, spun right threw 2nd with slow launches just riding the clutch out, i know i could have been in the 13s if i had tires.... or more power lol,

10lb bottle with 75 shot lasted me 19 runs..... so much fun


cheers

i was also thinking about going with nitrous but dont know what program to use .. calum or jwt anyone have any opinion on this...what supporting mods do you have?

hey

my car is sr20ve h/i/e, thermo spacers, timming 5deg (when spraying), and apexi vsf, calum basic (with ve setup), the nos set up is a zex 75 shot wet with smart box, bottle heater and purge, and gauge. fpr and gauge set to 3.5bar.

like how big shot u running and what ur goals?

i found when i did my first few runs my fuel was to much like 10.7:1 so i use the apexi to lean it out to 12.5-13. the car pulled hard. I am using the smart box its uses the tps voltage to activate when full throttle. I like this system because i just program the box and go.

well i have a sr20de lowport 200sx ser...i have fuel pump,bc cams i was looking to install to help me get at the 200hp mark with spray...i know that timing needs to retarded when spraying but not sure how to do that? am i going to have to retard the timing everytime i spray or is there an ecu program to take care of that?

i have the same setup on my sr20de and i cant wait to spray it! i like the zex box with the full throttle sensor. its just a pain to have to turn it on in 2nd at the right rpm and whatnot. im starting with a 50 shot and moving up to 75 once it get everything straightened out. im going to be using my apexi S-afc to tune my fuel.

leave your timing at base timing,i thinks its 15 degrees on the calum basic for ve,might be lower but anyway 5 degrees is to low for 75 shot,when i ran a 75 shot on me de felt a whole world of a difference at 15 degrees compared to following the instructions and retarding it to 13 degrees.i know its for saftey but just make you got a step colder plugs,fuel pressure bumped up if needed and just check the plugs for detonation after every run,you will feel a big difference

^^X2 I lowered mine to like 11 for a 75 and it felt like shit, then I bumped up a little and the difference its quite noticeable.

What are you revving your car out to with the VE and nitrous? I plan to run the same setup, except with n1 cams.
