i know this shouldt even be in here but no one else seems to be able to answer me a 4.6 mustang 02motor with 11.0-11.5 compression stock bottom end is it safe to spray it? i know this is a ls1 forum i wouldnt even ask if it was a ls1 i know the answer. can someone please help me

 

125 shot whould be very very safe

 

yeah with that 125 shot, it might put 300 rwhp to the ground lol

 

125 shot is fine. At 150 you need to get a wideband and a fuel pump. I have had 2 friends blow up their 2v's on a 150 after spraying 125's for over a year each. Both cars after pulling the plugs leaned out.

 

everyone ive talked to either said dnt spray it at all or dont go more that 75 shot and make sure i run atleast 104 octane so i just wont spray it i need a ls1 bottom end lol
