is this possible? im trying to decide if i should go with a 200-250wet shot but idk what it will handle... here is my setup

90k mi 5.3
ls1 intake
218/224 .550/.550 114lsa
tsp pushrods
zo6 springs
arp rod bolts


if i go nitrous i plan on milling my heads to 10.5:1 compression and buying the following

1 3/4" long tubes
ported TB
arp head studs
42# injectors for e85

 

thats alot of juice! The main concern would be fuel for that much nitrous! If you need a new motor then spray the house down but if not i would consider a little less of a shot! but then again more experienced people will chime in!

 

If the tune is right, it should hold it.. What noids you using? Plate? nozzle? Whos tuning it? you goin to run 93octane?

 

a 2 stage 200 you can do.. there is a guy with a stock 4.8 spraying a 225.. all in your tune and a/f

 

I'd leave the heads alone. I'm not to sure about this, but the added cylinder pressure added by the nitrous won't like the added compression. but thats just what I heard others will chime in.

 

get a video

 

well i planned on doing a nitro daves 78mm plate and keith mccord or lowe performance will tune it when its done

should i stay around 200?

 

I wouldn't go over a 200 shot but that's me. I'd do a 175 all day long

 

so i should do something like this

5.3
706 heads cut for ls6 valves valves (basically just cutting the intake for a 2" instead of 1.89")
arp rod bolts
arp head studs
LS1 intake,PP billet fuel rails, and ported TB
218/224 .550/.550 114
ls6 springs
tsp pushrods
LT's
Nitro Dave's 78mm plate
175 shot


and it will be SD tuned for e85

heres the HP numbers i came up with on each of my shots

175 shot should but me around 445hp to the wheels (556FWHP x .8 to acount for 20% drivetrain loss according to dynosim rounded up)


200 shot - 470hp (586FWHP x .8 to acount for 20% drivetrain loss according to dynosim rounded up)

250 shot - 510hp (636FWHP x .8 to acount for 20% drivetrain loss according to dynosim rounded up)

 

Why mess with a 250 shot....Go big or go home, 500 shot. A stock motor will take that no problem, on 87 octane.
