How big a shot can I spray on a n/a ls1? It is completely rebuilt ls1 with head studs

 

Pill it til you kill it, then back up one

 

Keep it under 200 so you can enjoy it for a while.

 

roadkill did 150 i think o his ls1 but was in a transam went 9.9 stock bottom end with allth goodies though...200 i think would be good if u not looking to brak any records

 

150 HP is defiantly safe but i have known of people spraying 200 and having no problems. The main thing that you will need to do is make sure your tune is pulling out the right amount of timing and just watch your plugs, and make sure your not going lean. You would also want to run a colder plug something along the lines of a NGK BR7EF.

 

Depends on how far you want to push it. If it were me, I would try and stay below 200.

 

Thanks for the input guys. Im wanting to get it running for the ls1 truck meet at SAR and would like to get some good numbers. Not looking to break any records just a new pb. I have all the supporting mods to spray a decent shot just want to make sure the shortblock can handle it.

 

as long as the tune is dead on i wouldnt see a problem with running a 200 all day long lol

 

You need to make sure you don't run it too rich. It would have to be extremely lean to hurt something.

 

I have a wideband to read my a/f plugs are ngk tr6. Tuning with hptuners. Still havent had a chance to try out the nitrous on the engine though. I think i will stay at a 100 shot so my transmission doesnt take a dump
