Ordered Kit, Kit 5115 Delivered today, Installed today. I won't run it until I understand how it works, this is the first dry system I have installed. Can someone i.e. Wyldman or BABolt explain to me how the engine gets the extra fuel needed for nitrous. The Pressure TEE seems to be the key device, but how does it work?

Thanks

SuperChip on Order
GearVendors OD Install Scheduled
8.8 Rear w/4:56 being built install w/OD
Copied BABolt on the wide wheels and got a out of balance condition that required removing and redoing one wheel..
No2 In but not operating..

 

By the fact that it is a dry system, there will be no added fuel into the system. What you can do is:
1. If you have a chip run a nitrous program to pull timing only a few degrees.
2. Modify your ACT (air charge temperature) sensor. There is a web page that shows you how to do this and my friend Hot V6 posted it here over several months ago. this will allow you to fool the computer into thinking it is seeing a cool inlet tempetature and keep the fuel change Rich.
3. Check with High Risk he may in fact have the best running Nitrous system.
4. The tip about the ACT. You don't have to have nitrous to use that. The ZX2/ZX3 guy use it.

Thanks, BABolt. Thee instructions say that "Necessary fuel flow is accomplished by increasing the fuel pressure and fuel flow rate." I have installed nothing that interfaces with the electrical system to increase fuel pressure. And the only connection made to any part of the fuel system were the Fuel Pressure safety switch & the pressure TEE conection to the fuel pressure regulator. Sorry but I can't see how this would change the fuel pressure.

Still Puzzled... Was hoping to get it saddled up and out tonight.

 

The way the system provides more fuel pressure is the hook up to the pressure regulator. The regulator works on vaccum. The nitrious is sprayed into the vaccum system making more vaccum and opening the fuel pressure regulator farther providing more fuel pressure.

The info that "forsfed" gave you is good. He gave you the basics for control over the fuel pressure requlator. The info that I gave you was just some extra items. (I did not try to take your post off track)Do have Superchips give you a nitrous program on you chip. I do have one and I in fact tested it on the dyno to make sure that it would work. One additional item there is a book called "How to install and use Nitrous Oxide" by Joe Pettitt and is sold by NOS. It is good to have around.

I need to ask you a question about the fact that you list an 8.8 axle in your bios info. Is there a reason why you switched to that. Was it so that you could run a 15 inch wheel.I hope not! I now have 15 x 10 inch wheels that will fit the Lightning and will give you your choice of real drag slicks (vendor and tire size).

Thanks for the advice guys. Still haven't hit the button. I like to disable the horn with the switch and use the horn to activate the NOS. It was a lot easier to trust my other set ups that had a direct fuel source that was activated with the nitrous. It's been raining so I'll keep puttering..

BABolt, the 8.8 is because I wasn't able to locate anyone making 4:56 gears for a 9 3/4
rearend. I was told maybe, maybe this fall they would be available. I picked the 4:56's because with the additional OD activated it puts the final drive ratio back to stock. I would also be interested in a couple of the items you posted recently including the wheels. The 8.8 was available in the f150 pre 99 so it shouldn't require to much fab to get it in. I think I have your email address someplace I'll try to dig it up and contact you that way..

Thanks

 

US/Strange, has 4.56's for the 9.75's. If you go with the 4.56, you will have to use OD for sure in 1/4 mile run.This would NOT be good for the 4R100.

BABOLT:
Are you sure on the 15 inchers. I tried with a weld and a centerline wheel and no luck.

Oh, Boy Jig. Could you give me info on the source or contact I have tried several people who carry those and run into several brick walls. I think I've bought every 4 wheel drive mag out there and called just about everyone who advertised gears with no luck.

Thanks for your help..

If it works out I will have a fresh 8.8 for sale, any one interested?

Oh yea, the GearVendors unit is rated for up to 1200hp and is fully shiftable at full throttle. Have to wait and see if it works as promised..So shifting into OD should be no problem you could have as many as 8 forward gears with this unit. Shifting from 1st OD into 2nd w/o OD ? I'll keep you posted.

Did you see the photo of the wheels in the other thread. This is not vapor ware also there is no junk there either. You would not believe the specs. on the adapter or the quality of the wheel. These thing did not just happen over night. In the case of the wheel I sent e-mail and followed it up with a phone call to almost all of the major wheel manufactures (hey I may have missed one or two). The plan is to try out the first set on High Risks Lightning. I could go on and on but it is late. One last thing I went out cruising tonight in my "stang" and some punk was pissed that I would not race him. I told him to meet me at the drag strip and I would clean his clock. I gave him a hint ( I have the quickest natural aspirated 4.6 2 valve in the country) he just laughed. I don't lie, BS or make junk parts.

MNLightning, how did you come up with 8 gears? Do you have a 2 speed rear end or an extra gear OD gear in the transmision that gives you an overdrive 1,2,3 and 4th ? Please let me know I would like the flexability of a low rear end for speed and a higher rear end for hiway driving. Thanks.

 

REDHOTL the unit is bolted to the tranny and has a .78 gear reduction. It can be operated manual mode or auto where it kicks in speeds over 45 mph. It may be a few weeks before its in the truck.

 

BABOLT:
You didn't just bite my head off, did you
I'm sorry if I gave the impression that you make "JUNK PART'S". I just have not seen a 15 wheel on a gen.2 Lightning YET. When I tried the centerline, it would not even start on ( bead over rotor/cal.). If you have some thing that works, GREAT would love to see it and how much?

Kevin
No I was not trying to - bite off your head. I guess I was reacting to the start of your question plus I was feeling a little testy when I came in yesterday evening. Having some punk challenge me to a street race over and over. Back to the wheels it took a little bit to figure it out. The rotors are 13.1 inches in diameter but the backing plate / emergency brake mount is approx. 14.5 inches. Did you look at the photos.

MNLightning, thanks for the info. Let me know how you like it once instaled, this sounds like a winner.
