Does anyone know what the biggest shot you can run without having forged internals becuase the forged stuff is twice as much 125?150?200?
Thanx for the help!!

 

For a V8, 125 is relatively safe. By 150 you start risking damage more in hammering out rod bearings. As far as I'm concerned, anything above 150 should have a forged bottom end.

 

I agree. The most I'd ever run on a stock bottom end is 150.

 

I ran 160 hp shot on my stock bottom end all last season. I ran every weekend. I also sprayed 200 the last two weekends of the season, but I wouldn't recomend that large of a shot i only did it because I knew I was going to be pulling the engine after the season. When i tore the engine done however I was totally shocked at how good everything looked. Anyway if you're looking for reliabilty I wouldn't go over a 125.

 

Im not talkin about stock its 5140 Steel SIR lightweight rods, std/std cast crank, KB Hypereutic pistons ist a complete rotating assembly from Eagle.

 

What's your ring gap?

 

^^ what he said . ring gap ! when i was spraying a 350 shot i had the ring gaps out to .030". i broke 7 pistons spraying 300 on .020" ring gap.

 

Yup, I'm running a 300 shot w/ .032" gap on the top ring. Haven't sprayed yet.

 

What should the ring gap be if i hit it with a 150 shot

 

Contact the ring manufacturer, if it's the stock rings/pistons, then run it on the rich side w/ conservative timing.

 

on my tpi a 150 wet shot has been totally safe. i don't even retard the timing or switch the PROMS... Im on my 27th bottle fill now, which is about 135 1/4 mile runs of juicing without any side effects. My motor is untouched internally and 149,000 miles old. i got the whole history on my cardomain site.....
i beat this car alot too...
