What size shot?
My pistons should be coming in by the end of this week. Motor will be going out to the machine shop.
Quick question, what size shot of nitrous can I run with the following setup: LE 234/238 .612"/.612" 111 LSA Trickflow 21* 185 heads Probe SRS pistons (2618) - Thicker nitrous deck, top ring seated lower... details in link below: (http://www.probeindustries.com/Produ...Show=TechSpecs) Callies Compstar H-beam (4340/5.7/3.48) rods Stock Crank (4 bolt main) Anywhere from 11.6-12.2:1 static compression I'm willing to run a nitrous dedicate fuel system. Gotta figure out what size shot of nitrous to have the rings filed for. Any ideas? Bigger the better... as long as it's on the safe side to run. |
Whatever you want. What did you build the motor to handle? If you wanna be safe, run 150 like people do on stockers. If you wanna have fun, get some jets with bigger holes and see what's the weak link.

Don't laugh but I really wanted to do a 250-300 shot using the Nitrous Express direct port setup but I'm terrified of it breaking.
And I wasn't sure if filing the rings that wide for a 250-300 shot would be too excessive to drive around occasionally. |
how far are the ringlands down from top of piston?
|
Better hope the rest of the car is setup for a 300 shot.
|
.240" start of the top ringland and the deck is .240" thick.
Piston seems like it will take a pretty descent shot. It seems like the most serious piston I could get without going with a custom set. Plan on running a Perfomabuilt 4L60E and Strange Dana 60 rear. |

Mine were .275 gapped at 28thous and used to hit with a 400 direct port (w/stand alone nos fuel system)
9.43 @ 147 facing the wall on the 2-3 shift |

Awesome. That's what I planned on doing. Getting excited. Thing should be pretty quick on a 250 shot.
|
Nitrous Outlet makes a sweet direct port set-up for our cars. The fastest nitrous LT1 in the world (Tony Shephard) runs this set-up...
|
Hopfully your not talking about the piggy back NX setup...
|
|
Do they even make a trans brake for a 4l60 anymore? That converter is going to flash pretty high too. Are you getting one with anti-ballooning plates?

As long as your ring ggapes right, your tune is on, and you use proper fuel there is no reason you can't go 300+HP

my brother,thing about this...........
make sure u have a goodddddd,fuel,delivery,255 pump,to start with..

Cool cool. I'm excited. I think I'll stick with a 250 shot on a dedicated fuel system.
Worth running the stock trans (as far as I can tell all it has is a shift kit) or just have it built while the motor is out? |
