:icon_frow Guys,

Tomorrow I will rice in a 1/8 track, versus a SRT4 with 450 HPS, so right now my problem is that I run 9psi of boost in a 1/8 track with my new Turbo setup ( Hot side .68- .70 A/R), so I want to use the NOS for anti lag system.

What size of NOS nozzle do you suggest to use for q 1/8 track?

The engine has good compression, is stock.

The good mods :evil2: :

Walbro
RC injectors
Lex AFM
T4 Turbo
Big intercooler
water injection set at 10 psi
Apexi II
NOS

The bad mods :
18" wheels
Wing


What size of NOS nozzle do you suggest to use for q 1/8 track?

Thanks!

how much power do you make .. If you are already around 500ish to the wheels ..you are going to need a different fuel pump.. What size tire do you plan on running ?.. What gears are in your car ... If your just using it for spool then a fifty shot should get the job done .. one more question how much experience do you have drag racing... seat time ?

My goal is 500HPs, but I don't have the opportunity ($$$$) to test it in a Dyno.
( also I want to wait for my new engine with a forge pistons, Fyndanza cam and may be a new 262 camshaft)

I will use my normal Tires Falken 18x8.5 Rear Tires.

I'm amateur :cry: ,

The last race my best time with the stock CT26(11psi) was 9.15. but my reaction is not to good, and the 18” don’t help.

By the way the supra is my DD car.

With nitrus your gonna spin more I would almost say that it might slow you down I would get some tires, work on your launch and then worry about the nitrous.

My guess would be as big as your chassis will allow, by this I mean you'll be traction limited so I'd start very small and increase slowly until you can't hook and your times are hurt.

id go for a 50 shot. i think spraying at launch will just roast the tires tho, esp w/ a small sidewall like you have. i think you may be better served borrowing some real tires.

reaction time wont effect your et. it doesnt start the clock til you roll out of the beams. you can sit there for 2 min and still run the same time. just thought id mention.

Guys,

I very disappointing, my best time was 10.20seg, WHY!, because after 4k RPMS with no more than 11 psi of boost, my A/F ratios drop below 10. so the car begin to fail WHY!, this problem do it with 16 psi, or 11 psi, even 8psis, I think this happened when that car is at WOT and over 3800K RPS.

What can I do, I will check the error codes lather, but really I’m desperate, I reduce the fuel %7 in with the apexi, with out luck.

I think is not normal, with my old set up I don’t have this problem.

Old setup:
CT26 stock (set at 14psi)
Venom 550c injectors
Lex AFM
Pressure regulator set a 28 with vacuum
Normal Intake Manifold

New set up:
PS .70 A/R
RC 550c injectors
Pressure regulator set a 28 with vacuum
New FFIM
