: N2O injection, exhaust, intake, and tranny mods
Gentleman,
Quick question about nitrous...wondering what systems people are running..dry vs. wet? And if running wet, at what power level (100hp+)? And where is the extra fuel pump is placed on the wet systems? Also curious if people have had success with the K&N intakes that have the MAF sensor incorporated. Also curious if any one is using the Banks exhaust? I am deciding between that system and the Gibson. And finally does anyone have any ideas on how to firm up, quicken, and move shift points on this tranny?
What I'd like to do is go with a cold air system, highest flowing cat back system, and a good nitrous system. I'd like to try and get into the low 15's/high 14's. Anyput is greatly appreciated.
Regards,
Sam
SMOKEDYA2 12-12-2004, 07:13 PM dont run dry nos it will lean it out and cause damage. there is a guy running a 50hp wet shot and knocking a second off his quartermile time. says anything above a 50 shot and there are no positive affects, he has no aftermarket fuel pump though just stock. thats probably why he cant run more then a 50 shot, the pump cant keep up.
as for the k&n FIPK I have one and havent had any problems, there all right for MAF sensor as long as you dont over oil them. I also have a gibson duel side swept catback exaust. with these 2 mods im running a 14.81 @ 93.6mph and a 0 to 60 in 6.8sec.
the guy running a 50 shot of nos is running in the high 13's in a crewcab. he has an aftercat exaust and a drop in filter with box mods. but no intake.
I dont know anything about the tranny firmness though. hope that helps
Dont think you are going to be able to do anything about the shift points until later next year hopefully. The aftermarket for the Titan is really just starting to see companies jumping into making products for it. It will still be months before we see anything like this.
SMOKEDYA2 12-13-2004, 04:31 PM i just wrote a email to the venom company asking about a venom 400 control module. they responded and said they were planning on making one for our trucks and that one of the things they will do is to improve shift points, air fuel ratios, timing advance, and others. they said that they do not have the information or parameters on our computers yet and to write back in 1-2 months and they will have more info for me, mabye even a part #. so hold on a control module is coming for our trucks
KL99SEA 12-13-2004, 10:16 PM Hey smokedya2......is your time/trap at a track or Gtech......trap seems high from what I've seen for our trucks. ET sounds ok but trap is a few mph higher than I have seen NA.

thats a track time, ran the g-teck at same time and got same ET but speed was 2 mph faster. stock for our trucks ive seen anything from a 15.0 @ 92mph to a 15.3 @ 89mph depending on packages. my best time I got is with 1/4 tank gas, no tailgate, and no spare tire. exaust and intake mods. knocked 2-3 tenths off time and 2-3 mph faster, thats right at what other people with same options are getting. the guy running NOS is hitting a faster trap then i am when hes not pushin button and he has a crew cab, mines only kc. it all depends on driver, elevation, temp. of air, and humidity.
SMOKEDYA2 12-14-2004, 06:05 PM The Head, is the gentelman running in the 13's. I belive his last posted time was a 13.97 @97.4 mph with the 50 HP shot
Thanks for all the input. Do you guys have any thoughts on this scenario?? Instead of a NISMO supercharger why not go with a 150-200hp progressive NOS system? Am thinking that as long as an addtional fuel pump can feed enough fuel to the engine it should not be a problem. If one can keep the engine from going lean and/or detonating I think this may be a cheaper/better option than a supercharger. Secondly I wonder if the supercharger kit is going to come with extra goodies like more robust con rods, con rod bolts, lower compression pistons, good headers, etc.

Sam
SMOKEDYA2 12-14-2004, 10:08 PM personnally I would rather have a supercharger then a 150 shot of NOS, just because I like the idea of having the power on tap at all times and not just when I push the button. would rather save for supercharger 8O
OldSalt 12-18-2004, 11:13 AM If you are going to mod your truck all that much, you may have to go to Hypertech to have them build a custom power programmer for your ride. Their existing programmers enable you to adjust shift points and shift firmness, raise the speed limiter to match the tires you're running, etc. They don't have one available for the Titan yet, but they'll have one soon. Their programmers are designed for mostly stock configurations, with a drop-in filter and a catback system. Like I said though, if you install headers, a CAI, etc. and send them the info, they will build you a custom programmer to match your modifications. Also, most modern blowers do not require any engine mods at all. They are bolt on kits. I believe that they come with an ECU that will adapt your engine to the blower.
SMOKEDYA2 12-18-2004, 12:59 PM I have called and wrote hypertech several times asking about a programmer for our trucks, and every time I got the same answer "We only make products for chevy ford and dodge, none for nissan." they aslo said they had no plans to ever make one for our trucks.
I have got good response from the company Venom about there venom 400 control modual, its in the works basically.
the_head 12-21-2004, 09:31 AM I run a wet system. No extra fuel pump. I did hook up a mechanical fuel pressure gauge and determined that I was jetted way rich on my fuel. I have popped in a set of ~75hp jets (with the right fuel pressure factored in) and run a 13.77@98.1 mph. On the same night I went 14.79@91.9 mph. It was cold (like 55 degrees) but there was about a 8-10mph headwind (hence the lower mph).
Right now there is only one company I know of working on a programmer for the transmission. Here is the link to their site - it is still in work.

SMOKEDYA2 12-21-2004, 05:45 PM great to hear from you again the head, i see you droped your time with nos again, good job. how is the computer running while your on the button? you got your OBD-2 laptop hooked up now right? whats your fuel pressure at now with the 75 shot? our trucks are defintly cold blooded, its 10 degrees up here in michigan and you should feel the power it puts down being that cold out 8O :D
SMOKEDYA2 12-21-2004, 05:47 PM ooops clicked that twice
Gentleman,
Thanks for the input. The tranny in the Titan is one of the few things I'd change. To me it is slushy and slow when shifting up or down. At any rate I have looked at NOS systems, and I am leaning that way. Am curious to know which system the head is running? Thinking that mid to low 13's are possible on the bottle at 100-150hp. Now wouldn't that surprise the hell out of some people? The Venom 400 also looks interesting. I guess we'll have to wait and see if that comes to fruition. The supercharger may be the most interesting option out there (when it becomes available), but I personally don't think that 490hp (if those figures are accurate) is going to come reliably from any small block V-8 that doesn't have lower compression pistons, stonger con rods, bolts, good headers, etc, etc. Hopefully we'll have an answer this spring. I am really interested to see some dyno figures and what mods are going to be necessary for the supercharger. By the way cold air does rock for making horsepower. Can definetly feel the difference here in Denver when it is cold. Beats the heck out of summer when it is 100 degrees out and the DA hovers around 10000ft.

Sam
the_head 12-22-2004, 08:54 AM I bought a used wet system on Ebay for $310. I've spent some $$ on stuff like a bottle heater and some fittings to plumb it. Closest thing that is "new" from NOS would be the 05131 part #. There are other kits out there and any generic wet kit would work. I'm still having inconsistent results from anything over 50hp.
My logged data shows that I'm still rich, even on the runs that I'm not getting any gains from dumping more nitrous in. Fuel pressure remains at 51psi no matter how big of a fuel jet I run. Timing actually shows more advance than just motor, again no matter how much I dump into it. But the thing is, this scanner takes time to get the data points. The more parameters I request, the slower the logging. So I'm still not quite getting the data that I would like to have but it is encouraging.
For the life of me, running rich and seeing no or little detonation has me puzzled why this thing just doesn't respond the the nitrous after 50hp with any solid, consistent results.
Are they advertising 490hp for the supercharger? I'll believe it when I see it. That's a huge gain to be throwing onto these motors.
With just ~75hp jets I'm almost running mid 13s. I would think with a 150hp you'd be knocking on the 12 second door.
SMOKEDYA2 12-22-2004, 05:31 PM the pics and claim of 490HP are somewhere on www.freshalloy.com its under the whats new section
the_head 12-22-2004, 09:47 PM Apparently he "talked to a guy there". I'm just skeptical at a 185hp gain. Not saying it can't be done but if it is going to be Nismo and come with some kind of warranty that it will not tear the truck up, I'd be really surprised.
SMOKEDYA2 12-22-2004, 11:10 PM i dont believe the 490 hp at all. with a decent supercharger intercooler combo I could see 100 to 120 HP and mabye another 110-125 ft lbs of torque. that would have to be at 10-12 psi also :!: as far as i know nissan is not going to warrenty the SC through nismo :(
shift 12-23-2004, 11:36 AM how much is this s/c kit gona be you think? and do u have to change engine internals to effectively run the s/c or are stock internals strong enough?
My guess is that the supercharger will probably run in the 3-5k dollar range. And I am reasonably sure that will not include installation. I am in agreement with smoked ya and the head in that I think 400hp is a more reasonable estimate for a bolt on supercharger. Probably similar in performance to say the Ford Lightning. In my opine to go to 490hp would require the mods mentioned above(in the thread) and would be fairly labor intensive. That power level would almost certainly require lower compression forged pistons, specific supercharger cam profile, etc. And if that were the case the kit price would certainly be much higher. Does anyone know if the pistons in the titan engines are cast or forged? Also wonder what the con-rods are made of? If the con-rods/pistons are forged I would be highly tempted to mod the heck out of the engine seeing as how it already has a forged crank. It looks as though these engines come from the factory a bit de-rated. And that they really respond well to the standard hot-rod mods. Maybe next christmas santa will have a supercharger or better yet a turbocharger for out trucks. We'll see and in the meantime we'll just keep showing tail lights to those other trucks

Where did you hear Hypertech will have a programmer for the Titan soon??? I've contacted them twice (most recently last week) and they said they have no plans to make a programmer for the Titan???
GETSOMZ28 01-30-2005, 01:03 AM I am sure the 490hp is rated at the flywheel, so you are looking at a 140-150 gain at the wheels which still seems optimistic since that would probably be around 8-9psi...Not sure how long the motor would last at those levels?!?

It doesn't surprise me that detonation is non-existent with your set-up since you said that your running rich. Typically they say you should pull 2 degrees of timing out for every 50 shot of bottle but in my experience, most newer V8 vehicles can soak up 100 shot with stock timing and 91 pump gas. The rich condition your experiencing is most likely helping as well. Have you pulled your #1 plug and checked your color? If you don't have any specs on the porcelian I wouldn't worry. I ran a 50 shot of Nitrous on a 1.6L 4 banger once with absolutely no modifications to anything except cat-back exhaust and custom cold-air intake. I ran somewhere around 35 10lb bottles through that car with no problems at all. Nice pinkish/brown color on my plugs and all was good. Where did you mount your bottle? If you decide you want to display it, let me know. Check out the bottle bracket I had in my 1996 Z28. I am a dealer so let me know. They typically only come in brushed aluminum but I might be able to arrange another polished one. Makes filling the bottle a breeze and setting the optimum 15 degrees is simple.
the_head 01-30-2005, 05:32 AM I put mine behind the right rear passenger seat.
Hmm how much for a complete setup and how much to have something like this installed. Would be really nice for the new season at the track.

Nice and tucked away. I like that. What about a blow down tube? Are they strict where you race or do they even know you have NOS when you go through tech? Any under the hood pics Head?
