2008 nissan 350z hr 175 shot wet.. Anyone have tried it
Ok my car has a 150 shot but only 133whp gain so it should be a 133 true shot cus im not gaining 150whp with it ... Also i have been trying to find out what things i need to tune my 350z with E85 ive read that i need large injectors fuel pump and change some fitting in my gas lines .. Do anyone know if i have to change all my gas lines or injector or i can use stock ones .. I can make alot more power with the same shot just using E85 any info is appreciated thanks thanks guys
Yea i have right now 133whp gain from nitrous i will be happy with 155whp gain or 160whp gain im not gonna be using it too much maybe 3 times every 2 week i dont want to blow my engine or anything i will be going to tampa z fever to retune higher when im rdy but im trying to tune in E85 to make more power i need more info about it
1. up your jets to 52N 30/32F (both sides)
2. Depending on timing, afr and bottle psi this probably will result somwhere at 80-90whp per side or up to 180whp (sae correct dynojet).
3. You should run 100+ oct race gas (Sunoco GT 260 or VP equivilant)
4. Forget E85 as the conversion cost outweighs just buying race gas at the pump where available.
Then stand on that mother-fer accelerator every run letting that whole hit come on at 3400-4200 rpm. Do this across 10-15 bottle refills.
Then come back to this thread and post your results.

For clarity lets stop using the term "shot" as it is really meaningless. Lets also assume all hp sought is whp, not crank. Since you seem insistant to run this I think you need to....

^ What he's trying to get at is that longevity will probably be an issue. Plus, the gains you're seeking is not worth the risk. But, like I said, you seem set on spraying a bigger shot so go ahead and do it already. 
With respect to E85, it looks like you have a lot of reading ahead of you.
You don't magically make more power with E85. You make more power by running cooler, cleaner, and with more aggressive timing. In order to harness the power of E85, however, you need bigger injectors as you'll be using more fuel. Much of the reading I've done suggests that the cars made in the recent years do not need to have the hoses, lines, etc changed out for E85 use. E85 is ~105 octane so think of it as race gas. As far as UpRev goes, I have no idea on that.
In the end, if all you're doing is a few drag races here and there, E85 conversion or Flex Fuel conversion is not going to be worth your time or money.
FWIW, back when I was drag racing and spraying, I used to just buy 109 octane gas from the track as I wanted to be safe as possible without a tune (I still don't have a tune, lol).

go direct port and get a tune u will be fine. I gain ~160hp and 240tq off my 150 shot. and that's on a de and I'm revving to 7200. go search and find my directport thread and also dynotunenitrous.com is a good place to get any nitrous parts you need.
and fwiw I ran 150 shot single fogger on pump gas with stock tune for awhile before the direct port setup.

Can it be done? = YES. Should it be done? = Maybe\No. How many times can you get away with it? = Who knows. True - HR is beefer to some degree but don't be lulled into believing they are indestructible. .

Also I believe that the spray would be disproportionately allocated amongst the cylinders with such a large shot. I am also assuming something close to 175whp. To make that the Zex charts seem to be pushing you to 52N (both sides @125) or 250bhp, which will probably dyno closer to an additional 40-60whp over and above your 133whp gain.
Also will you run leaded race gas, E85 or 100-109 unleaded?
Are you progressively controlling the hit? or is the 100% spray hitting your drivetrain?
Finally - I would guess you would only get like 3-4 solid bottle psi .25mile runs before having to refill a 10lb bottle.

Yes! - Now here is a worthy read. Very interesting setup (also very custom) as that what DP always is for our cars.

2Bad...Is the stock block still holding for you? Your thread also mentions that you had pooling in the intake with the single nozzle @150 jetting.
Brought these issues up to the original poster, but he wasn't having any.
I built three engine after that and they all spun bearings. Now I'm doing a 2JZ swap.

Sup guys...long time no see. Nitrous junky here. Let me hit these things one at a time.
E85...you gotta run 30-40% more fuel to make the same power with E85. This means bigger everything in your fuel system. Multiple pumps, new tune, big injectors, fuel lines, etc. Not really optimal for nitrous. If you are worried about detonation, just run C16 or C23. Run similar volume as gasoline with a higher detonation threshold. E85 is better for boosted cars IMHO.
175 shot. Most EFI kits that run a single nozzle have a range of 35-150 shot. You start running more than that and you have issues with atomization (sp?). That's all of crap going down the intake into the throttle body. Direct port would be better suited for bigger shots like this. Another thing to consider is either a progressive controller or a dual stage setup. A progressive controller will bring on the spray easier so that you don't shock the engine with 200-250 lb/ft of torque all at once. This is really what kills the motor and the reason why you see boosted cars making more on a stock motor than nitrous. Boost builds gradually, nitrous is usually all at once...which is hard on the bottom end.
The dual stage is a viable option...spray your 100-150 on the first stage, then have the 2nd stage (100-150) kick in at a higher rpm. Since nitrous is RPM dependent, by the time the 2nd stage comes online, it won't have near the shock effect that a big shot would down low as you start having less nitrous in each revolution at RPMs increase. The cost for a second stage isn't bad. Another nozzle (or set if you have two intakes) and another set of solenoids. I would definitely consider some sort of software or ems to tune both stages if you're running two big shots.
A progressive controller works pretty good as well and can be used in conjunction with a dual stage, single stage or direct port setup. I would probably use a progressive controller on a big single stage direct port setup. Start it off at a certain percentage and ramp it up with the revs. The only downside to this is it starts to feel more like boost than nitrous. I love the kick in the pants spray gives you...but having this effect also gives you the ability to run more power without destroying the motor.
Would I run a straight 175 shot in a single stage efi kit....no, not personally...especially if 150 hasn't given me any issues. 150 shot felt nice when I had a stock block Z. Anything more than that all at once, and you spend more time spinning and less time moving. Just some things to think about...do whatever you want, but alot of guys on here have run nitrous years ago on these cars (myself included) and know what the limits are on the parts nissan puts in these cars.
Happy spraying.

This is what i call a great explanation wowwwwwww. So give me some opinion ..
Right now im running 150 shot of zex jets in my hr engine but im only gaining 133whp from it i dunno why my car is not making too much torque ... My car makes 403whp and 394tq but like i said im only gaining 133whp with the 150 shot my engine is stock all i have is test pipe , intake , full exhaust , fuel pump, clutch and all that ... What do you recomend me to be able to raise the shot without blowing the engine remenber is a wet shot ... Should i install a second stage so i can run the same 150 shot im running and another extra50-75 shot or what u recomend me i just want to do everything right and be safe .. I dont really use nitrous too much i use it like 3 races per month. But when i use it i love to be fast ... so tell me what you recomend me and whats the max shot i should run in total and in each stage.... Thanksssss
