ok im finally running a 383 ls1. im gettin a magnacharger in about a week or two. and i wast to add a 250 shot of nitrous. i think im running. 9.5 compression now and ill probably keep it the same for the supercharger. should i lower the compression for the nos set-up. im thinkin of gettin the venom computerized nos set up and make it spray at lower rpm;s and shut off when the supercharger pumps out max boost. any ideas.

 

1st....what car is the 383 going in???
2nd...its a 382, not a 383
3rd...a magnacharger will not adequately support a 382 unless it is a VERY tame cam and heads...
4th...spraying a 250 shot on a supercharged car is simply not done...not is anything resembling a street car
5th...the Venom is the most unreliable piece of **** nitrous system out there...
6th...its nitrous not nos...
7th....sounds like someone has been reading too many hot rod books, talking to too many 18 year olds about cars, and really wants to go fast.
8th...Just do the 382 and nitrous, and keep the CR between 10.5 and 11.5:1.

not trying to be a dick, but your post makes you sound like a very young or inexperienced person who wants to drive to the "spot" and talk about his Nawwss and blower....

Wow. SDB you pretty much took the typing out of my hands. A maggie with 9.5 sure no problem. A 9.5 with a 250 shot, kind of needing that big to make up for the lack of compression, unless your cams spec'd for it. Together, oh brother. Ok, a 50-75 shot on the maggie I could see, for additional cooling effect but come on a 250 shot? Half the nitrous users on this board dont use above 200shot. And lastly, one thing SDB forgot, the maggie doesnt need ANY nitrous as the maggie will pretty much top boost once you realize your not sitting still anymore. The boost builds from idle, and once you roll it continues building additional power so for a "lag" remover Nitrous wont help you out much. As a charge cooler it will.

250 would break something real fast. Thee extra fuel ya would need to supply alone would be appaling. You can make all the power you want withj a stroker forged and a blower. Lower the CR to 9-1 area and you are golden. GL mate

382 turbo and alky... nuff said

 

heheh you guys are tough

 

ya the "382" is in my 92 camaro as you can see in my sig. im just trying to push 600 to the wheels and making it street legal. if i can do it without nitrous so be it. ya im rather unixperienced with this. but hey what the hell...im 19 and work on multimillion dollar aircraft. so i guess that makes up for it.

 

well since you work on multimillion dollar aircraft (ones which i plan on flying in a couple years i might add) then you have the knowledge to stop calling it NOS! NOS = Nitrous Oxide Systems. Call it nitrous. And a low compression 382 with FI will exceed your goals, no need for spray.

 

Or you could do a 383 with a 100 shot and still hit 600 to the wheels.

 

Woah, I run a 300 shot on my supercharged 383. (not an LS1)
stage 1-200shot
stage 2-100shot

I need to modify my sig, last year I ran 14 psi, but this year it droped down to 11, because of a cam change.
And it is definetly a mild mannered street car, and I only run pump gas.

 

This is different, he's wanting to run NOS, not nitrous.

 

and since i have the knowledge to see the word nitrous in the accronym i can call it "nos" if you make it through basic you will learn the accronyms and youll make everything shorter also b/c it is much easier. so until any of you come from my point of view you really cant talk.

 

I think you'd be around 500-550rwhp with just the blower, so a 100 shot would get you to 600rwhp or more.

Viper, people aren't trying to bust your chops, most of us really don't like the "ricer" language. Most of us would go out of our way to spell nitrous instead of using a terms like No2. I personally don't think there is anything ricer about No2, but if someone says nawz then I have to draw the line. As for the question at hand, blowers and nitrous require 2 diffrent piston set-ups. Blowers are low compression, nitrous likes normal to high compression. Either one will get you over your 600 mark with a good heads/cam set-up. If you've already bought pistons for either set-up, just go that route. No need for both.

 

see thats what im talking about. someone that that actually is tryin to help me instead of correct my grammer. using accronyms like "nos" or "no2" is just easier and quicker. i understand that nitrous is more grammtically correct. so maybe i should forget the NITROUS. anyhint special i need to do with the s/c set-up. i was told i would need copper gaskets and stuff like that.

 

and why is it called juice? i dont put what i drink into my car? does anyone else?

 

You don't NEED copper gaskets. A set of Cometics would do just fine...just make sure the place doing the block work knows you're running Cometics and knows how to prep the deck for them. What are your goals for the car? Track, street/strip, cruiser?

Oh and NO2 is nitrogen dioxide...not something you want to spray in a motor.

 

viper6913, I lived through Basic Training back when you were wearing pull-ups and it was acceptable to be rough with recruits, and theres a few others in here. Acronyms are accepted, just use the right ones, and dont take some us too personal, but learn, thats all we ask.
Are you building a small block chevy and not an LS1 I would recommend hoping onto one of their forums, not that you wont get info here, but you know how it goes.
Low compression, generally 8:1 - 9.5:1 depending on method of FI and other stuff is typical of the LSx engines. Cometic head gaskets, but at 600rwhp there are some ppl surviving with Stock MLS (multi-layer steel). forged rods, and pistons and decent flowing heads, as its FI you wont necessarily need top name hogged out heads for your goal. I would recommend a custom grind camshaft, I use Ed Curtis, can send you info if you like. Have you looked into a turbo setup? I understand Banks makes a beautiful kit for 3rd Gens, I could be wrong, but look into it.

haha I was waiting to see how long it would take someone to realize that.
Can't believe someone didn't call it on the first post after.

Ayways 383 + ATI (forget the magnacharger) = 600+ rwhp easy

 

ya i looked at a twin turbo set-up but i was told that it might not even fit under the hood and i already have the ls1 and the tech at banks said it wouldnt fit in my engine. id rahter have tt's instead. if anyone has tt's under the hood of a third gen preferably on a LSx please send websites or pics forums or anything.
