New to nitrous, but I want more power.
I got a rebuilt LT1 (maybe 3,500 miles) it has a cc306 cam in it with stock heads, stock TB, 30 Lb. injectors.
Can someone point me in the direction of a nitrous kit that wont blow my engine.
If not whats the safest way to spray without forged internals.

 

www.harrisspeedworks.com High quality parts and great customer service....prices are very fair as well........Just make sure to implement all the failsafes in your installation and it should be alright for a long time.....I've had the bottle on mine since Aug of 98 ..........IMO, I would Go with a "wet" style nitrous kit(I've run both, and like most people MUCH prefer the wet systems for their easier and more precise tuning).........Make sure to have a properly working fuel pump, "confirmed" with a fuel pressure gauge that you can observe during some quarter mile passes so that you know for 100% sure that you have adaquate fuel while the car is under load.......Make sure to have a FPSS (Fuel pressure safety switch) hooked up so that your nitrous solenoid will "NOT" operate if the cars fuel pressure ever drops below your preset minimum "safe" pressure setting.......also going with 1-2 steps colder plugs is good insurance against damaging detonation(the autolite 103's are a good choice for anything up to around a 150 RWHP shot and can be found at pretty much any auto parts store)......also make sure your plug wires are in good shape as well....that stuff is the real important stuff.......other items that are REAL good ideas if you have some extra cash and want things as safe as possible, is a good aftermarket ignition box like a MSD digital 6 box (or Mallory 685).......this way you'll have a nice hot reliable spark, a window switch(with the mallory unit) and VERY importantly, a rev-limiter that drops spark for it's rev-limiting action , and NOT "fuel" like the factory rev-limiter does.....it's also a "real" good idea to have the factory PCM's rev-limiter raised WAY up out of the way so that it will never be in the picture on a nitrous car(7200 is where mine is).............the key to running nitrous safely is to just make certain that the nitrous to fuel ratio NEVER EVER goes lean on fuel.......and you don't get too greedy with the shot you run......a 125 RWHP shot is about the most I would go if you really care about the longevity of the engine...........good luck with it..........PS: it's also a good idea to list your year car in your sig so it's easier to give acurate recomendations for certain things ..........Joe

 

As long as you run the safety gear as noted above, and don't get too greedy with the jetting, you should be fine.

 

alright ordered this kit http://www.harrisspeedworks.com/shop...9&cat=0&page=1
And a MSD box. What else do I need to get (thats not in the kit). any suggestions.
oh yeah I also plan to get the Racetronix fuel pump kit.

 

A fuel pressure safety switch is a definite. A purge valve and bottle heater would be a couple nice accessories to have. Also, a window switch would be a very wise investment.

 

Factory rotor in the dist. is not going to like the MSD box.

 

and what makes you say this....

I have a MSD Dig6 and the original stock Opti....the msd has been on the car since 00-01...I have personally put ~40k miles on it and 200+ drag passes.

Can list many more close friends w/LT1's using MSD boxes w/no opti problems caused by the MSD

 

word.

 

I'm running the cc306 on stock heads with a 150 wet dynotune kit and have ran some 11.30's with that combo heres the slips and spray it.

 

Lows 11's are a nice run. Hope I can get close to that.
What do you run without the nitrous shot.

 

^ what he said, and whats the rest of your setup? auto or stick? gear ratio? on ET drags? etc......

 

On the motor, I run 12.50's at 108 on a 1.70 60 foot time.
I have 4.10's in the 10 bolt, 3600 vig, pacesetter LT's, Lt4 knock module, true duals, stock heads & throttle body, moroso CAI, dynotune 150shot, 28x10.50 slicks

UMI torque arm, LCA, panhard bar, eibach springs with air bag in the pass rear, comp eng. rear drag shocks

 

At what RPM does the nitrous come on? If before your stall rateing of 3600, how much does it raise the flash of the converter? I'm thing of going with a Yank 3600 next year with a 100 shot. I was wondering if the nitrous would help flash the converter a couple of hundred more RPM? Thanks, Rick.

 

The nitrous comes in at 3000-6300. I flash the convertor from idle. I would say it goes up to about 4200-4400. Thye car 60 foots 1.70 on the motor and 1.55 on the bottle.

 

are you pullin those 60's and time with a stock 10 bolt?
