dual stage nos ????????????

detonation beats up the pistons and bearings. and too much timing will lead to detonation.

Right. I understand that. But my motor has absolutely no pre-detonation. I messed with the timing for a while on the dyno when my car was on it at the end of last year. It seems to actually like it.

yea and 40-42 that seems like an awful lot of timing just my $.02!

Well you are entitled to your $.02...and if i did not see it for myself i would agree with you 100%. I dont understand it. I just know that other people (some are well known) have done this same thing on sbc's and ran for years...the motors just seem to like it.

Just remember on a digital 6 you are limited to 9 degrees of timing that you can retard, so that alone you wont be able to hit it with 2 kits

I myself am not looking to hit 2 kits. I have only sprayed 100hp at the car and am looking at a 200-250hp shot with a controller over maybe like 3 seconds. Just not sure how much time to bump out. The ignition i run is a 6AL. So i set it at the distributor if i know im spraying. I would like a digital 6 box but i dont want to spend the money on one right now. Anybody have one they want to sell?
 
We pull 2 degrees for every 50 that we put to it, but we also play it safe some people do things different but we follow NOS advice
 
On the timing issue I know lots of guys running 40 Degrees of timing and motors love it, but I am also a chevy guy cant speak for the Ford folks. These are high compression Raised runner type motors mind you.
 
that does seem like alot. I know its an ls1 but I run 40 at cruise and 28 WOT N/A
My elcamino liked 34 NA

Yup. Mine is 22'ish degrees at start and i think the smallest mechanical advance bushing i could even get was 18 degrees. The timing is also fully advanced at about 2000-2200 rpm's. So basically anytime im driving it, it is damn near fully advanced.

why do you want to run a controller. they slow you down. unless your car goes on the bumper and just blows the tires away there is no need for one. and my buddy does have a dig 6 box for sale brand new i can find out today how much he wants
 
Plus a controller pulses the solenoids and wears them out real fast. Very costly to keep rebuilding them. Control it all with timing

At the end of last year the car picked the front end up about 2-3 feet off the ground on motor and im not sure how much more i picked it up on spray(100hp). Im afraid that on a 200-250hp shot the car will either 1. not hook 2. do like you said and plant the back bumper on the ground 3. destroy the motor with a hit that big and all at once. The main reason for the controller was to ease the motor from taking the sudden hit of nitrous. I know it will hold together then, but i am very skeptical of the motor surviving all 250 at once more then a handful of times.

Right. Im aware the controller pulses the solenoids and wears them out. I would rather rebuild/replace the solenoids every year or so then drop $10,000 or more on a new motor. And as for controlling it with timing. I heard of some people's ignitions taking timing out on the launch and then bumping timing back in automatically as they get going down the track.....but only to whatever s they specified the total timing at.
 
With a 7 programmable you spray it all up front and pull out more timing on the launch then slowly ramp it back in once the car hooks and is on its way. That way is easier as you want to hit the tire and chasis with as much as it can handle. Its possible you need a chasis adjustment if it wheelstands to bad or maybe put weight up front. Just an idea
 
A nitrous motor is not gonna live as long as a procharged or a turbo car no matter what you do, as long as you got a lightweight rotating asssembly and valve train it will however increase the time between rebulds
 
Im just worried because the rod bolts only say they are rated at i think either 750hp or 850hp. The rods themselves and the crank are good up to 1400hp with proper rod bolts. I was told if i hit with anything over 150hp then i would be pressing my luck. But if i introduced the nitrous at a slightly slower pace the motor would be just fine.
 
If its rod bolts your worried about they can fail at the top end also especially hitting with spray, but I would be more concerned about Rpm

Rpm is your is like the devil shits cool as hell but can ruin your day fast which sucks with nitrous motors they like to scream at least everyone i put together has..

My shity big block has factory car rods in it prob the worst rod ever made for it. Then put heavy ass 800+ gram trw slugs on the end of it and you got a bomb.

I havent had it on the rollers yet but for the mph I seen outa it I'm gunna say its close to 650-700 hp with a solid tune on the on kit. I have yet to spin it hard on the kit 6k shifts tried to go higher once an it started to pop (valve springs) It has gone to 7400 on the motor though when i was to busy watching someone get smaller in the mirror than paying attention to what i was doing.

I'm sure it'll come apart this year should be a mess when it does.
