How much can I run on a factory L98 bottom end before it turns inside out? How much can you run with nothing more than a cat back exhaust? Thank's

Seems like people run a 100-150 shot pretty well on stock v8s.

That is what I thought. There are things in the works for the wifes GTA and I want to see a little blue bottle in the trunk.

I use to run a 150 shot on my last Z with a stock bottom and had no issues after about 20 bottles went through it

my 305 held up to 10+ bottles of 125-150+ shots for a couple years and never quit not even before i swapped to a 350. opened the old 305 up and it was clean as a whistle no issues i could find what so ever.

If you do it right 150 shot won't hurt anything. But be carefull that stuff is like crack. Once you spray it you can't stop.

i know this is old but hopefully someone replys, i wanna get nos for my 89 iroc tpi 350 but i dont wanna blow it up, i have 13x,xxx miles on the engin but its my only car so i cant blow it up but im sick of only getting like 200-225 horses to the wheels, 2010 accords can beat me D:, so i was thinking 50 75, MABY MABY 100 shot?

go 150. just tune it right and let go of the button when u have a feeling something is wrong. never take nitrous away, add more fuel when tuning. i went carbed so it was very easy. im sure FI itll be 10x worse to tune.

noob question what would you change (engine wise) in order to make sure you dont blow up the motor, pistons?

That's actually a pretty hard one to field. There's a lot that can go wrong when you crank up the horse power. Stock pistons should be fine, along with stock crank shaft.

Valve springs would be a good place to start. Ideally, some nicer springs will prevent your valves from staying open past the timing of the cam and getting slammed into place by the piston returning to TDC. My dad blew a valve up through his hood like that once.

Probably the best thing you could do would be a high flow/ electric water pump and some other cooling system goodies.

good to know ill look into that before I spray it....just want to make sure it stays put

i would suggest forged parts if u have the money. it allows for more tunning "error"

what forged parts?

Forged parts meaning rotating assembly: Pistons, rods, crankshaft. Forged is always a lot more forgiving when it comes to abuse than the OEM parts. That being said anything will break with enough abuse. I've seen a completely forged assembly with ARP fastners rip the top off a piston with 22 lbs of boost and too much timing.

If you search around tho it's been stated on here of guys running 150 shot on stock 350 without issues.

Well im only thinking of a 100 shot so Im sure it will hold on but if there's something i can change might as well.
