20g plus a 50 shot of wet?

[1sick91tsi]

ok well i can get a great deal on a wet n.o.s wet kit and i was thinking about putting a 50 shot on. now i wanted to know what you guys think about it? will it be safe to run? and what else is anything do you think i will need mods wise? here are my mods

20g turbo running 19 psi, 2g throttle body elbow,full 3' magnaflow exhaust, test pipe,, dejontool intake pipe, magnecor plug wires, k&n air filter,2g maf, 650cc injectors, turbonetics extranal gate, 2g ports ex.manifold, halman boost controler, fluidyne rad, slim line fan, buschur front mount with short route piping, crushed 1g bov, 2g o2 housing, s-afc, data logger, autometer egt gauge and boost gauge, rebuilt engine with new oem piston/rings .20 over. arp rod bolts, arp head studs, rebuilt head, and a act 2100 6 puck clutch.

thanks for the help -karl

You don't mention what kind of fuel pump you're running, but I certainly don't think you have enough injector for a 50 shot unless you want to crank the fuel pressure to lower your IDC's. In the final analysis, I really feel like you could make more power by tuning the motor to run 24-25psi and forgetting about the nitrous, but I'm sure others may disagree.

Just my .02,

sorry i didnt realize that it wasent in there, i have a 255 with a afpr. but you dont think 650s are enough? and do you really think i would pick up more hp running 24-25 psi tuned then a 50 shot? i read that a 50 shot is like 100hp to the crank or something. but in any case thanks for the help!!

I'm going to have to disagree. The size of the injectors isn't going to make a difference with a wet kit. A 75 shot felt a lot different to me then the 50 shot did. I think you would notice it more than a few psi of boost.

That's all well and good, but we're not talking about a 75 shot.

Thanks for the correction on the injector sizing. I had automatically assumed a dry shot.

Sorry I should've been more specific. I ran 20 psi and a 50 shot and 22 psi and a 75 shot and then 24 psi with no shot, all on the same turbo(18g). The 20 psi with the 50 shot "felt" a lot faster than the 24 psi alone.

Nitrous works well, and helps the turbo come on. On my FWD I ran 12.7x on a 16g alone and 24#'s, with a 50 shot wet, I ran 12.0x with the boost creeping up to 25.5#'s. Make sure your ignition system is is exceptional working order as well.

I've always heard that with a FI car, the equivilent of a shot in a NA car will be twice as much in a FI in terms of kick and stress upon internals.

Why not a 50 shot on 25lbs? I too myself am thinking about putting a 50 shot on mine but I don't really have the mods. I have a td06h, 550cc's, 255lph fp not on yet, fpr, 3" turbo back, intake, fmic.....

I think I'm going to wait until I have the rest of the mods on there. Do you think a 50 shot would be safe on an engine with 152k?

The energy created by the nitrous tends to make the turbo spin a little faster so you get a bit more boost. That's why it seems like the 50 shot is more like a 75 or 100 shot. Nitrous is safe if it is tuned properly. If you are going to try a 50 shot you should run colder plugs, retard your timing a few degrees, and possibly increase your fuel pressure a couple psi.

What do you guys think will have a better performance effect a 50 shot or cams for 1/4 mile use ?


Just for teh record I know that cams will be a every day benefit while nitrous is only benefiting you while driving but this is simply 1/4 talkin.

 

[GVR4592]

The 50 shot. There is now way you'll get 50+whp out of off the shelf cams.

Yeah I just read a article in 2NRS mag that they put nitrous on this pink 240sx drift car and I shit you not the affect it had was identicle to what a stroker does. It moved the power band to the left and it had a more linear torque curve not to mention the added whp . I am seriously considering keeping my stock cams and sprayin because I already have a smim which I regret getting before cams but now that I'm in this position and money isn't coming out my ass cause I'm safving up for my own place I think a 50 shot would be better for my needs then cams. I know that zex now has a direct port kit that you can get down to 50shot what would you guys think about that instead of cams on a car that is dd and sees action only on the weekend.

What are you using to tune with? What plugs do you have? Do you plan on using race fuel with the nitrous, or are you going to be using pump gas?

DSMLINK, BRP7ES, PUMP GAS(93 octane)

Why you don't think pump gas will be ok for spraying?

 

[GVR4592]

I would go with some BPR8ES and see how your car likes them. You might have to play with the gap a little to prevent them from fouling, but your engine will be much happier while you're spraying.

As for the pump gas, I would be very careful. Decrease the boost a few psi and pull at least 2-3 degrees of timing with the Dsmlink nitrous controls. Then if everything is ok(no knock) start adding the timing and boost back in slowly.

Those plugs are a little extreme for everday use though. Granted they would be better for spraying but I will be not spraying a lot more than I am sprayin. The reason i think spraying is a better mod for me then cams right now is cause I very rarely race cars that are of my caliber seeing how is most kids have ricer burners around me and anyone that has a descent car I'm friends with cause it's a dsm . Anyway I would spray maybe 3 times a month tops and it's mainly to give me more down low torque and power. I don't plan on spraying more than a 50 shot really as that willbe more than enough.
