I was wondering how big of a Dry shot I could get away with and be somewhat safe <img src="gr_stretch.gif" border="0"> I already have a Walbro inline pump but I am going to change the intake pump as well so I will have both.. I may go to 3.42's to run a bigger shot my RPM limiter is set at 7k. I am currenty running a 100 dry shot I was thinking of going to a dual stage dry kit 50 out of the box and then a 100 shot after 2nd. My other mods are in my sig.

I have a 98 on a stock fuel system and I can run a 200 shot all day long, so with your walbro pump and 28 pnd injectors I say you could run a 200 shot without a problem...

a) DO NOT listen to the post above. I think the guy is mixing up dry and wet kits.

b) with your HP level and fuel system, I wouldnt go above 150, and Autotap religiously. You should be okay.

c) If you run a 2 stage, I would go wet/dry, but a two stage dry shot will work with 2 nozzles/solenoids. FWIW i would go 50 out of the hole for traction reasons and 100 in second.

Chris Spiess

Instead of a 2 stage, thing about getting a progessive controller. You're overall performance will be better since you can control how quickly you ramp up to 100% after launch and since you don't hit the tires with all the extra power at once like a 2 stage. There was a guy in the chicago area with your same setup - intank pump and 30# SVOs - on his 98 running 175 dry w/o problems.

Sorry Ryan but you sound like you should be on LS1.com or something, and yes, I have run a 200 DRY shot numerous times on a STOCK 1998 fuel system with many witnesses, this was done with a NOS ProShot cylinoid and I have had no problems whatsoever, so unless you have proven facts about it being impossible, and not hearsay, please don't reply to my posts unless you have knowledge on the subject being spoken about and keep your second hand info on LS1.com....

RyanJ

why dont you keep your bullshit bickering to other sites. and thanks for implicating LS1.com. Thats one for the things we like to keep off this site. ******I******* would never recommend 200 dry to anyone with 28.5# injectors and a pump barely sufficient to 550rwhp. you do whatever you want.

418 rwhp = roughly 418*.16=67 hp loss or 485 hp that your fueling with 30 lb per hour injectors..... At 30 pounds of fuel per hour they upport roughly .45 lb per hp hour= 67 hp per cylinder or 533 crank hp at 100% duty cycle.....a rare thing....... that 533 crank hp at a 90% injector duty cycle is 480 crank hp......Your already making that.......so squeezing looks really really dangerous....... I would step up the injectors or run a wet kit......of course this all assumes that your fuel system can keep up....... As for anyone that can run 200 on a different car? It has no bearing on another car that is modified differently...... apples and oranges..........

I run a digital peak /hold egt gauge for both na and esspecially nitrous or turbo applications......that way where ever it makes best power na... I tune for the same egt on nitrous as well......no guessing......all hoping and guessing will get you is a pile of broken parts...

you sound like a true dipshit, I have proved time and time again that you can run a 200 dry shot on a stock 98 fuel system, is it the fact that you are mad because you don't know ****, and might look even more moronic if you agree with me? Is this why you keep arguing?
Oh and LS1.com = ****

I have a real problem with your 200 dry shot even on a stock car.....What are you actually making......can you post a dyno sheet?

We all know that a stock ls1 makes 300 rwhp and thats 348 crank hp about.....+200 hp worth of nitrous = 548 crank hp.......or 460+ rwhp.....but with a 28.5 pound per hour injector at .45 bsfc thats 63.33 hp or 506 crank hp.........at 100% duty cycle but figuring 90% is alot more real world max since the recovery time at 6000 rpm is about 2 ms that leaves about 18 ms to inject, a 80% duty cycle....(Im giving you a 10% advatage)

Anyways 90% of your 506 is only 455 crank hp period.......with a 28.5 pound injector......and thats maxed out.....no more fuel.......so your making about 93 more crank hp then your inectors can flow...??????Thats about 17% more than is possible to fuel...????Can you fill us in how you do it.......I ve got a set of 72lb inectors I need to make more power with......so this can really help me out.

What happens if the injector goes STATIC? I have a 99, and with STOCK fuel system and I have sprayed mine with a bigger cheater solinoid and NO jets (app 200hp) with NO problems. But I was also using 118 octane fuel. My autotap read 100% duty cycle on the injectors!!! OOOPPPPSSS!!!! <img src="graemlins/fluffy.gif" border="0" alt="[Fluffy]" />

OK, I had a 5177 kit, but the max HP we could get out of it was 125, so, I bought a Powershot noid from Holley and installed it, I ran the 200 jets, and it ran fine. Unfortanatly the car hasn't been to the dyno, but speaking on personal experience, it is possible to run a 200 dry on a stock 98 fuel system, and there's two other guys out here with 98s that are doing the same thing as I am, with no problems except for traction....

It looks like there is no evidence of it actually being 200hp...It may very well work.....but so far I only have two things to go on...

1. 11.83 to a 10.58 on 200 isn t the drop I would expect.....I have a car that runs 12.30's na and 10.30's on 200......309 rwhp to 505 on the dyno.

2. I had a dry kit that when jetted to 150 made 114 to the wheels.....

So I guess the real question is a 200 shot actually 200 esspecially when the systems are altered...

This is exactly right, the 200 shot dry is I'd say about the equevalant of a 150 wet, I will we running a 200 wet as of next week.....My opinion on NOS isn't really a good one, their kits are weak and the techs at their center have no idea what they are talking about, I wouldn't even waste my time on a dry kit if I was just starting out...NX and TNT wet only for now on...night and day difference from dry

RyanJ

i still dont have any proof of your fabulous 200hp dry shot. also, dont the 5177 kits some with powershot or superpower shot solenoids?? do you mean Pro Shot??

Your still babbling Ryan, let me make this clear for you so you can tell the kiddies at school about it when you get off the short bus. The kit originally was a 5177, i.e. came with the Powershot noids, I purchased a Pro Shot cylinoid and adapted it to the kit, i.e. the Pro Shot flows a lot more juice than the Powershots, thats how 200HP dry is achieved. Now if only your mommy can read this to you before your bedtime... <img src="gr_stretch.gif" border="0">

what does this say you dumbass. POWERSHOT. Im not stupid, people have been running Cheater and other solenoids with the 5177 for a LONG time, about the time they realized that 125 was the max for the kit. What im saying is that I WOULD NOT RECOMMEND A 200HP DRY SHOT TO THE HEADS/CAM IN QUESTION BECAUSE I DONT THINK HSI FUEL SYSTEM CAN TAKE IT. If you wanna run your injectors well past 100% duty cycle levels, thats fine...but if you read the first line of the first post he says "somewhat safe." If he stepped up to bigger injectors with a 200 dry he'd be safe. ****I**** dont think the 30's will cut it using the same math that 1320 posted. BTW, how much gain did you see and what octane did you run with the 200 jets??? Not everyone likes to run 118 leaded like Silver. <img src="gr_stretch.gif" border="0"> Now step off your high horse, lighten up, and have fun. And dont talk down to me like I havent been ******* with these cars for the last 3 years.

I would not recommend doing this either,you may getting away with it,but may someone else wont.If a can hold my breath for 10min doesnt mean you can.

XSuROsISX

dude, I'm not trying to be a dick, I just hate it when people say **** can't happen when we have been doing it for a long time, I'm not looking down on you in anyway, and I know my motor will most likely explode anyday now, I'm just saying it's possible to do even when the math says it's not, don't take this bad your second post just pissed me off when you tried to make it look like I didn't know what I was talking about when in all actuality I've been blowing up my Camaro's for the last 5 years...

RyanJ

I wasnt trying to be inflamitory in that first post. There's a surprising amount of members on here and other sites that still dont know the difference between wet and dry. They are the same type of person you though I was when you were replying. we both jumped to conclusions. No hard feelings here. And for the record, this whole time my purpose was to not recommend doing a 200 dry, not say it was impossible.

happy new year.

i just wanted to throw in 2cents, but im broke so ill give a TTT for hell of it. PS can we just help the guy out and stop fighting over who can do what? ive ran a 200 wet when noone said i could an now im gonna do a 2 stage. so, what works on some cars wont on others but from MUCH first hand knowledge the pistons wont last,wet or dry. just have fun and break something hehe <img src="graemlins/camaro.gif" border="0" alt="[Chevrolet]" /> <img src="graemlins/fluffy.gif" border="0" alt="[Fluffy]" />
