i was wondering how much nitrous my car can handle is has callies rotating assembly,eagle rods, J & E flat top pistions. AFR stage 3 aluminum heads. LT4 intake that has been ported and polished to match the heads. It has a 58mm throttle body on it. The headers are Hooker long tubes. The computer has been reprogram by Ed Wright. any info would be greatly appreciated. the guy i bought it from told me no bigger then 150 wet shot is this true? and should i get a wet or dry set up?
thanks

 

i would run wet.

as long as you have an upgraded fuel system and the bottom end is FORGED then you should be able to run upwards of 250. remember that tuning is everything, and at that size shot direct port is the way to go. also a fuel cell would increase safty.

 

what do you mean by "forged"? all iwas plannin on runnin was 100 wet shot maybe 150 would this be save with the set up i have now?

 

there are two kinds of internal components, cast and forged. the difference is how they are made. forged is much stronger than cast. if you have a cast bottom end i would stick with a 150.

 

thanks for the help. i think my set up is forged but not for sure. the guy i bought the car from hasn't sent me the build sheet for the motor yet.

 

 

If you have a calies crank, eagle rods, and je pistons then your bottom end is forged. These are quality parts, and are good for 700+ hp. You're fine with a 150 shot, but as Drew said, "tuning is everything" when you step it up.

 

well my car supposedly dynoed at 510 at the wheels, haven't seen the dyno sheet yet. so i'll be ok with a 150 shot? i don't want to go too crazy i was just thinkin about doin a 100 but i haven't decided yet. thanks for the help

 

You should be fine with a 150, but start with the 100.

make sure you have enough fuel pump/pumps for the motor and the additional nitrous. I prefer to run a dedicated fuel system just for the nitrous. You may want to tune this in on a chassis dyno, preferably with a wideband o2, just to get the tune correct. At this hp level, you can hurt a motor in a hurry if there is anything off on your air/fuel ratio.

 

we would all be interested in a dyno sheet. does the car run with a lope? is it a m6 or auto? how hard is it to hook the tires??

 

i haven't drove the car that much but when i did it was only 50 degrees and chilly out so i couldn't get much traction at all. i bought it nov 25 drove it for 10 days then put it away for the winter. but the guy i bought it from had the motor and everything done by nu-tek. but i made sure to ask him the rwhp and he said it was chassis dynoed at 510 rwhp and the tranny was built to handle 1500hp mcleod clutch aluminimun fly wheel all built to all hell. it has sub frame connectors and traction bars (i think) all adjustable suspension. he ran high 11's on street tires with a 2.5X 60 foot time. seems kinda slow to me but idk for sure but i am plannin on gettin nitto 555's this summer. he is sending me all the build sheets for everything and the dyno sheet as well(at least i hope so) does 510 seem really unreasonable? i read in a magazine a guy made 458 or somethin on a 395 but had ported lt1 heads adn intake. idk what the cam size was though either. and what is a "lope" sorry if i'm misleading you guys but thats what the guy said and he knew what he was talkin about cuz this was his 3rd car similar to this. but when i get the dyno sheet and see its less then 510 i'll be glad to post it on here and get things straightened out.

 

The reason the engine builder told ya not to go over 150 shot is becuase more than likely the JE pistons he used are probably Hypereutectic Alloy. These pistons and nitrous are not friends at all! The piston material changes to a brittle glass surface and will shatter like glass with to much nitrous.

Guess why I know this.

 

510 seems a little high. take some pictures of the motor. if im not mistaken the 396 nu-tek stuff is suppost to be in the 500hp flywheel range.

 

are you running straight pump gas?

 

it does run on a lope and i don't know if the guy used racing fuel in it when he dyno tuned it. what does your 383 have for hp?
