The sneaky pete adds about 20-25 HP and wont damage your motor. It basically injects just a slight amount of N20, enough to make your engine burn cleaner. You can run 60 Hp off N20 into a M102 engine with no problems. (185HP!) I have run 80 HP thru one before (colder plugs and 10% race gas) It will get the 190e 2.3 into the 0-60 range pf 7.5 sec and the 1/4 mile time of 15.7
with the Sneaky Pete expect 0-60 about 8.0 sec and a q-mile time of 17.0, Dont try to run the Sneaky Pete above 25HP without running the car richer. your air flow meter might not like it!

Had a newer model. He feel asleep at a red light and the green light didn't wake him up. Had my hand on the horn just about to honk at him when he finally woke up. I was afraid he'd fall asleep again so I went around him, and that really woke him up, but there wasn't anything he really could do about it although he tryed He cought up to me later in traffic and flew by be to show me he was finally awake.:p

speedtek-Well those results are what I am looking for, that will give me the edge i need. The cheapest Sneeky Pete i found was $209, and i am attatching the website, is this the right one? just want the confirmation before i go ahead and purchase it. jim-did you race him with the 5-speed 2.6? nice win. when i am in my friends camaro(i rarely race my car), after we race somebody and win, i love it when they race by you as you go the speed limit, which just makes you feel even better about the victory, knowing you not only beat him, but also made him look stupid, because he only got past you when you were going the speed limit. so nice w. http://www.jegs.com/cgi-bin/ncommerce3/ProductDisplay?prrfnbr=1727&prmenbr=361

Speedtek, I looked at that sneaky pete, it looks really cool. I wanted to know, how does it get the nitrous in the car? it looks to me like it goes in the air intake hose? its not direct injection, say to one cylynder right? it goes into the throttle boddy via the air intake right?

If thats the case, that sounds like a neat little upgrade. I may consider someday for my car, but I was thinking a bigger size might be better suited for the 24 valve 3.0 in my car. I looked at this, and thought that sounds like it would work well, or do you not recommend going with naything bigger than a sneaky pete on a 4 cyl or 6 cyl benz engine.

I would only use it on rare occassion just for a burst if I ever did it.but I wouldn't want to damage my engine.

Also when would one optimally want to enage it for optimum benefits?

Heres the universal kit I was looking at.

NOS Universal Kit

This universal kit is adjustable from 35-75 hp shot for any multi-point EFI 4 or 6 cylinder out there. NOS designed the kit for Sport Compacts, Mini Trucks, and Euro Tuners that do not have application specific systems. The kit includes NOS ''Soft Plume'' Fogger Nozzle, a 10 lb. bottle, Hi-Flo bottle valve, -4AN line from the bottle to the Super Power Shot solenoid and -3AN line from solenoid up to the nozzle. Also includes necessary mounting hardware, wiring and switches. Bottle shipped empty.

I'm assuming a fogger is an air intake nitrous, and direct port is of course direct into the cylynders?

Sounds like a fun project, even if only used once ina rare while. just knowing its there would be cool.

Though I'm plenty happy with the speed of my car and dont race people, I have always been curious about what nos feels like fromt he drivers seat.

I could write a book on this subject!

1. Nitrous is a FULL Throttle device. The best way is to have a trigger switch that operates the solenoid when the throttle is over 90% open.

2. The Sneaky Pete injects a small amount of N20 into the engine.
You may have to run the car a bit rich to get the correct air/fuel ratio. This can be easily done on some CIS-E cars by fooling a sensor or adjusting the car rich. On some cars that have oyxgen sensors to that operate on FULL Throttle the car will actually richen itself. That is why it is best to start with a small amount of NOS like 17-20 HP at first. NOS is addicting and by making the N20 injector size larger more HP is gained. Fuel also has to go along with this. But doubling the size of the injector orfice does not double your HP. It may QUADRUPAL IT! so play it safe!

Single orfice!:
.014" = 8 HP
.018" = 12.5 HP
.021" = 17.5 HP
.024" = 25 HP
.036" = 65 HP

So now you get the idea?? this is based on the proper A/F ratio.
If the car is lean you can make a .018" go up to 24 HP at 17:1 A/F ratio.
(I have actually witnessed a competitor drill his jets double size (.040" 76HP x 4 = 304HP) at the race track only to watch his rods come out of the case! This was on a 1600cc Toyota Hemi engine.
He was well warned!)

The injector is best placed before the throttle plate on the MBs, please make sure the N20 doesn't hit the throttle shaft.

When getting the jets from NOS (or whatever kit you are using) measure the size of the orfice yourself so you are sure that it is the correct size. You will need to buy a jet drill kit or micro drill bit set at a Hobby store. A dial caliper would also be nice. (buy the cheap digital one at Harbor Freight Salvage, it is accurate enough.)

The Sneaky Pete bottle only last one or 2 shots. A larger bottle is better (10 lbs), you will need to find a bigger bottle so you can transfer the NOS yourself. (It is very easy!)
I would really advise you find a standard kit and modify it into a Sneaky Pete. (single jet, NOS only)

Word of Caution:
1. Nitrous is an addictive POWER ADDER. If some guy tells you youre cheating he is just JEALOUS cause he doesn't have it installed in his car!
2. Dont forget it is a compressed gas that is about 900 psi underpressure. OBSERVE all warnings.

DIRECT PORT: Direct Port starts off with 4 or 6 .018" nozzles. (you can calculate the HP) depending on the number of cylinders you have. You will also have to pump fuel into each cylinder. On the MBs I add a second fuel pump that puts out 8-12 psi and regulate it down to 4 psi with .021" jets. you can fine tune your A/F ratio by adjusting the Fuel Pressure up or down by 1/4 pound increments. A fuel pressure gauge on the fuel regulator will be necessary. This installation is not recommended for a novice. I can go into details about the whole setup if there is really some interest.

SINGLE FOGGER or SINGLE INJECTOR
This is the fastest way to install NOS in your MB.
Fuel is taken off the main pump after the filter. you can adjust your HP by changing jets. I order the Single Fogger NOS kits from NOS and I tell them to ship me the old 84 Rabbit GTi kit. It has all the correct parts/jets to fit on a MB. The order number is not in any catalog, but it is on file with them. You can order it thru Summit. Retail is about $475 average.

With a 190e 2.6l you can get 6.5 0-60 times and 1/4 mile times in the high 14 second range on a 50 hp shot. You can't go too much higher without leaning out because you will be tapping out the stock fuel pump. (safe MAX about 75hp) 300E's are about the same due to the weight difference (about 15 sec)

Once you ride in a car with NOS you will be shocked! as long as the power is reasonable and you understand what is going on. and learn all the proper procedures. NOS can be safe and FUN!

If you live near Las Vegas I have a buddy who installs NOS on MBs and BMWs, I often travel there to help him with his projects.
Maybe we can have a MB BLAST-FEST?

speedtek, gimme a few months, I'll make the trip up to vegas and we can pop some nos in my car and see what she'll do

Thanks for the information, really clears things up. I thought they had one that goes intot he air intake, and mists the nos into the air intake where it is sucked intot he throttle body form there, but are you saying the best way is to inject it under the throttle body? or before the MAF sensor? or is direct port better.

I'm not looking to make it a crazy jump, but if I can have 35 hp at the push of a button, to be used only on occassion, would you recommend that vw kit for a good boost?

I will be in Las Wages mid June! Maybe for 2 weeks?

The reason we use the VW kit: it is setup for CIS already and basically all CIS NOS setups are the same. Just tapping for the fuel is the fun part. But we have custom made CIS adapters with the AN-4 fittings on one end. Then we set the level of HP desired.

so it will wokr as a reliable boost, without being on all the time?

Cause I'd love more power, but I dont want it on all the time, just when I want it on.

Sounds like a plan, I'll start saving now.

great topic! just wondering if this could be done on a mercedes V8 117/116 5.0? what sneaky pete could be used?

Thanks alot,
Scott

If you have a V8 install a regular kit. and get 80 HP more. I have posts and times on this website. do a search by name. It is so much fun racing vettes with my customers car. You should see the faces on these vette, camaro & stang owners when an ol benz keeps up or beats them!!
(450 SL runs LOW 13's without slicks!)

Well, I'm a little confused about the boost that a sneeky pete system will give me. It says it will add "that extra tenth of a second" in the quarter mile, but I don't need something that adds a tenth of second, if I am going to spend 220 dollars on some N20, i want more boost than just a tenth of a second in a quarter. Speedtek you seemed to think it would add more than just a tenth of a second in the 1/4. Were you talking about something different? If I get the regular sneeky pete system, how much boost would it actually give my 8v? Sorry guys, I don't mean to inconvience y'all, but I am just a novice! Thanks-Jesse
