Here's the deal, I'm new to S2000's, so I really don't know much about them yet. I traded my Evo for one that has the SOS stage 2 kit, upgraded heat exchanger, EMS, and all the other goodies. It has the 3.4 pulley on it right now making 436/284 (dyna pack) at about 14 psi on 93 pump. I love the linear power of the supercharger, especially for the twisty mountain roads around here. The problem is that it's starting to feel slow on the straight line pulls as I've gotten used to it. I don't want to switch to a turbo. I REALLY like my SC.

I'd like to try something a little out of the norm. At least it seems that way, since a search turned up nothing about an S2K set up like this. I know I'm near the limits of pump gas on my current set up, so here's what I'm considering: Switching to e85, keeping the current pulley, and adding a small shot of nitrous. Maybe in the neighborhood of a 50 shot. From my limited research thus far, it seems on a boosted car a 50 shot of nitrous is more like 75-100hp gain. With this set up, it will still be somewhat tame on the back roads I like to drive, but when I wanna do a highway pull or go to the drag strip, I'll have some extra oomph!

I'm looking for some input from people that know more about this platform than I do. It seems that the bottom ends are unbelievably strong for a factory car, so I don't think that will be a limiting factor. Will e85 provide the knock resistance I need for this? I'm sure there are plenty of things I haven't thought about. I should mention that I'm emailing back and forth with my tuner, but I like to get the opinions/experience of others also.

One of the biggest concerns will be the fuel system. I'm currently on a Walbro 255 and ID1000's. I'm thinking maybe a Bosch 044 in line? Also, from what I've been reading, the injectors and fuel lines will be okay if I increase the base pressure with an adjustable FPR, right? I'm guessing I would need bigger injectors and fuel lines to keep the factory base pressure. I don't really have a specific power target that I'm aiming for yet. I'm just thinking out loud.

So feel free to give your opinion, tell me I'm an idiot, or say whatever you think needs to be said. Thanks!

 

Try E85 first if its available to you, I think the walbro and 1000s are fine.Whats your duty cycle on the 1000s? Have you thought about getting a bigger blower? I wouldnt reccommend spray if youre looking for down low power, I used a 75 wet shot NA and didnt spray until 5.9k. If you want mor power uptop, it will be a nice kick in the pants...until a bottle goes out

 

Not sure on the duty cycle. Honestly, I'm really having a hard time figuring out the datalogging with the EMS. Ecuflash was much more user friendly on the Evo.. I forgot to mention that I have the Novi 1200 charger, but I'm not sure if there are better options available. From what I've read, the 1200 is one of the most versatile/best performing chargers.

I suppose I could just try the e85 first and see how that does. That would certainly save me some cash for now. As far as top end vs bottom end, a friend of mine had a 150 shot on his old S2K, and when the spray kicked in (I forget the RPM), he had basically his full hp and torque all the way to redline. It was pretty amazing how well it worked. Regardless, the nitrous would obviously only be used for straight line stuff. I don't know, I just have this desire to do something different.

Even if I don't do the nitrous right away, I probably will at some point. I know there are supercharger gurus and nitrous gurus here. Let's get a collaboration.

 

Too much complication. Go e85 more boost retune. Done.

 

Let me say wot gas mileage will be horrible because of the superchargers need to run rich as well as the added fuel needed for the shot of nitrous. Look into trying out a 1500 blower a member on here was able to put down good power with it on e85

 

I did read a thread where someone mentioned a 1500 blower, but he said the guy couldn't beat his performance on the 1200 until he spun it with like a 2.6 or 2.8 pulley. He also mentioned something about mounting issues, or rubbing the hood, I can't remember. Admittedly though, I haven't looked into it further than that.

The problem with adding more boost is that I can't run on e85 all the time. It's around a 40 minute drive to get it. I go to school near it, but I can't count on that all the time. I need to be able to have a safe pump gas tune.

I agree that it does add some complexity. The thing I like about it is that you can have the extra power when you want it, rather than all the time. It's not permanent. That would make it a little more controllable on the twisties.

Some pretty good points made so far, keep them coming! Anybody think it's a good idea? lol

 

I hope you go through with this, because that would end up being an awesome addition for a Kraftwerks kit..

Make like 360whp on blower and then spray a 100 shot on top of that..

Good luck with your search man, I know people have ran nitrous with centrifugal superchargers before, it's just not common on here.. But what really would benefit you by having the SC and nitrous is the TORQUE!! Your car will make more torque than a turbo s2000 that makes the same power, and torque is where it's at..

 

Yeah I completely forgot about the added torque that nitrous gives. Anyone have any thoughts on wet vs dry shot? Assuming the fuel system is sufficient, I'm thinking a dry shot would keep it a little more simple, since the EMS can handle the fueling. I'm still doing a bunch of research on this, but any info is appreciated.

 

Seems like a wet/multi port shot would be the safest method. I know there is some aftermarket double fuel rails etc that could work. Even distribution in each cylinder I think is important. You could probably step up the shot a little bit this way as well.

 

Definitely a wet shot. Heck direct port it with the sc
