Fresh topic - Nitrous on 1.6 8V?

[okcrawler]

Ok, I spent the weekend playin in the dunes. (yes, we even have sand dunes in Oklahoma ). The sami did great, but there were a couple of the biggest ones that I just could not make it over. 4th gear LO, on the rev limiter (tach goes to 6K, the needle was past that), made good speed, but could not hold enough power to pull it over. 3rd - LO, not enough speed. 1st - HI, too low, 2nd - HI, way too high... No such thing as a perfect gear, and you can't down shift during the climb.

The motor makes good torque (that's what I built it for), but there are a few times I'd like to make some real HP! So, does anyone have any experience/comment about adding Nitrous to the motor. I'm thinking something along the line of a 25 shot wet single fogger past the throddle body. I've always wanted to play with NOX, but never wanted to risk my DD.

Probably have to be a custom setup. Car kits are way too big, and motorcycle kits use too many injectors ($$$ extra). I've got a header and clean exhaust (no meow), so that should not be a problem... Hood space is very limited, and fuel pressure is too high to run direct to NOX injector. But, those are minor issues.

Just looking for some kind of short term, kick in the ass kind of thing...

Any thoughts...

Having had my zuk to the sand in Waynoka I know what you mean about need in that extra boost. I was there with the 1.3 and 5.89's in D44's on 33" boggers and with the V6 on 33" TSL's. The V6 and the auto did MUCH better due to the more power and the ability to downshift on the climbs but still need more power.

Riding the Raptor then getting in the Zuk makes it kind of disapointing.............. I've always wanted to throw together a 2wd Ranger with a nos'ed V8 and long travel- I friend of mine runs a (zebra striped) EB in tough truck and it is a blast in the dunes but the EFI 351 could still use a little boost.....

I'd be careful putting much juice on the stock Zuk pistons- although a 25 shot probably wouldn't hurt much..........

Now your talking!!!!!!!! Not sure about NOZ? Not to be a dick or a smart ass but why not trying a well.......... (looking both ways)........ Ricer board. Just an idea

Steve in the Blazer (44" TSLs and wore out 350 TBI auto) and Jayson's Sami (wore out V6 TBI auto and 38's) all climbed everything out there! I could get within inches of the top when it would stall. That SUCKS!

I don't know that big HP is necessary, but a bunch of Jayson's buddies were on Banshee's, and those things are just obnoxious! Can climb anything, anywhere they want. The dune buggies are just freaky. Never seen a stadium truck out there, but that would be fun..

I still had a blast. It just sux getting you ass kicked by any hill!

An 80hp motor should be good for near +40hp. Being conservative, I'd stay with about 25. However, that's kinda the problem. Most kits say start at 40 or 50. I don't know if I can throttle one down that far, if the fogger will work properly.

Flex - I'm afraid I'd really get flamed on a racer board if I suggested NOX on that motor, and only 25 shot as well..

[FLEXYSAMMY]

yeah guess you have a point there! Oh well looks like you'll have to try it and lets us know how it works!
Good luck Guniea Pig......

The guy i spoke to at NOS seems to like the idea (pondering for awhile) But i want it for mudd, wich he said that, if i burp the NOS, 100hp of NOS would work just fine NOT STANDING ON THE BUTTON. I already have a header and ported and polished head thats milled 10 thou. That made i big diff on its own. NOS soon for my rig

The only bad thing about nitrous is that you can't hit it at low RPMs. I think the general rule is over 3000 RPM. If you hit it off idle.....you get a heavier dose that what the kit is rated for.....and you bend/break all kinds of stuff inside the motor!!!!!

Don't know about on a 1.6 8 valve?

This was done on a 1.3 a few years ago by a guy in Oregon by the name of Rick Rodgers. He had a shop/company called Mild to Wild Suzuki's, don't know if it's still around though??

He was also one of the first to come up with the reinforced t-case arm that bolts to the ?front or ?rear output. He ran a samurai in many tough truck competitions at the big monster truck shows and similar events. He had problems keeping t-cases together from the jumps and general mayhem.

Anyway, He put together a nitrous setup, i believe it was using the forged swift bottom end, that would smoke 33" boggers through all 5 gears.

Get ahold of zukiman, here or on the orc bbs. He could probably tell you alot about the setup as he was the one i remember talking about it on one of the old suzuki email lists a couple of years ago.

Thanks, I'll try that.

I also found a discussion on the Toy board about NOX on 22re. I'm gonna try to get a guy that had a lot to offer on their project to comment on mine...

[okcrawler]

Well, here's what I've come up with so far…

The hardest part seems to be getting something below 50hp. I've found a single nozzle fogger kit by Nitrous Works that looks promising. It's capable of running a 24 jet for the NOX (~25hp @ 900psi). However, the fuel becomes a little more difficult. For my high pressure fuel system, I'll need to run something around a 14 size jet (yes, that's the same as .014"!). That is the smallest jet that NOS makes, and I'm waiting to hear back if NW also goes that low. It's gonna be close. I'll have to set the fuel at 14, then use the NOX jet to adjust if it's too rich (and most 'cal charts' are on the rich side). I hope that cheesy EFI ignition is strong enough. I may have to get back on that HEI conversion I've been thinking about..

One good news is, from the info I've found, I should be able to get about 6min of 'burn' from a 10lb NOX bottle at 25HP. That's good for 60, 6 second bursts! Or, about $.75 per use..

The kit will run about $450 new, which is not bad compared to some of the NOS stuff. Really don't have any feedback on their quality yet. However, it's a basic setup, without the 'bells and whistles' that others have. A couple missing options are, fuel pressure cutout (kill the NOX if pressure is lost), and an RPM monitor (I cannot activate it below ~3K, and MUST get off the button if the rrr's drop!).

Tonight, I'll pop the hood see if I can figure out where and the hell I can put the nozzle, and solenoids. My under hood is just way too packed… The nozzle mounts by drilling a hole and taping 1/8" pipe. Gotta find some place to put it before the runners without hitting the water jacket..

Well guys the Nitrous project is ON!

I started bidding on a new Nitrous Express wet setup on e-bay this weekend, and I got it for $330. I should have it by mid week. Since I'm sure I won't be able to use any of the jets that come with it, I'll have to call and order what I need. No problem, I've found several web pages which offer jet calculators. All you need to know is your fuel pressure and what size N2O jet you'll be running (sized for the HP you want).

So, I spent the weekend getting the truck ready. One important thing with Nitrous is having a good spark. That meant it was time to upgraded the ignition system. I installed a MSD Blaster 2 coil, and new 8mm Accel wires. This should give me a little more kick on the plugs, which is recommend because it takes a higher voltage to jump the gap when N2O is added. I increased the gap on my plugs to .032 and took it for a test drive. It did clean up the bottom end a bit, and the top end is pulling strong to 6K. I was real happy with how the bottom end feels stronger. I tested by running on concrete, 1st-low 2WD. I stand on the brakes and let the back tires slowly turn with my brakes holding the truck still (the neighbors just love the black marks I leave in the street ). I can almost keep the back tires turning at idle. I have to give it a little gas to keep from stalling, but I can easily keep the tires turning consistent with the engine at 800rpm. Before, it was difficult to hold the motor below 1000, and not stall or surge.

Now, the next trick will be setting the jetting on the NOX. I tried tapping into the O2 sensor and reading it with a good DMM. Well, that did not work, the readings are all over the place. Then I stumbled onto an old clamp I had for the EGT sensor on the race car. I discovered it would fit perfectly placed just at the end of the collector on the header. It would be better to have the probe right on a down pipe, but I think this will work good enough to give me some feedback. I drilled the exhaust, installed the probe and took a base line test drive. Forth gear, full throttle, 4K it's running at 1350F and climbing. I ran out of room before it leveled out, so I'm not sure if it would make 1400 or not. It cools down quickly at that distance, so it's not the best placement, but it should give me an idea when I hit the button if I'm in the danger zone. I'd like to see it cool below 1350 for starters.

I just hope my camera comes back from repair in time to snap some install pics….

Sounds like you are having fun with this project.. Keep us posted.

dunes in OK.. Who would have guessed. I want to see some pictures of these dunes!

-Wayne

p.s. I plan to enter my Zuk in the sand drags next year. I think I have a chance. a 200+ HP 4 banger might just cut the mustard.

My camera was broken, so I did not get any shots from the trip. However, here is the web site from the park: http://www.waynoka.com/photo.htm

We pulled into camp with my truck, Jayson's (sami-tube on 38's), and Steve's (Blazer-tube, on rockwells and 44's)! The words "wholly sh!t" seemed to ring thru camp! Every time we stopped on the dunes, we drew a crowd.

I found a site where they put a 150 shot on a Neon!
http://www.nitrousinfo.com/neon.html
Not what I plan to do, but WILD! It would be fun to do on an old 1.3 that you wanted to get rid of...

- For those that may not want to read the article at first, they ran a 13.8 @102 with a bone stock Neon on 13" wheels!!! -

[Pappa Smurf]

i know a way to get like 175hp out of a szuzuki 4 banger

[rotozuk]

Why do I have the feeling that Neon was a rental car?

Sand dunes look pretty nice. A little flat and hard, but hey.. They are sand!!

I have the issue of Mopar magazine that has that article in it. I don't own any Mopars, but when I was browsing the magazine rack and saw that article - how could I resist?

In that original article they say it's a rental car, and that they made all the nitrous installation mods with the fact that they wanted it easily removed and with no noticeable change to the car when they had to turn it back in to the rental agency.

They said they were able to drive ("limp") it back to the rental agency, and turned the keys in, and took off.

Was it really a rental? Who knows. I always kind of wondered about that, and if they were able to get away with it. The article said they thought they had some internal engine damage, but it would still run.

Thanks,
That's basicly what I'm gonna do. The 24&15 jet they quoted, from my info is about 25HP and what I'm going for. However, my fuel pressure is higher, so I'll be starting with a 14 jet (the smallest I can get).

Oh, my camera came in yesterday!! So there WILL be pics. I may put together a web page to document this project, so everyone here won't have to put up with the pics if they just want to read the progress. I'll post a link as I get started... I plan to do install this weekned, but I had to order jets, and I was told they probably would not be in 'till later next week.
