how many of you guys have sprayed 150 through your 5.3 and held up? I am gonna try it this coming weekend. My tuner is gonna take some timing out and we are gonna run race gas through it, probably 110. The engine is for the most part stock, with dual exhaust, custom intake setup, tune, and a walbro 225 intank. I am not gonna leave it on the truck, just have a few people that want to lose some money

Any input is appreciated.

 

Alot of people have done it, you will be fine.

 

spray a 250 shot, give em 2 lengths get 100 bucks more

 

lol, it had to be for money to make it worth my while to take the kit off the gto and put on the truck

 

ive contemplated buyin a universal type fogger setup and spraying my tbi for a while to raise some money for the 6.0 setup, then i would have it to put on the 6.0 aswell

 

As I've come to understand it, the engine will be aboslutely fine under the juice, but the transmission will under some amount of undue stress. I'd be more worried about the tranny...

 

well, if the tranny goes...no big deal. Ill replace it, i would like to have a built 4l60e anyhow. I guess i could use the excuse of the engine letting loose to buy a 6.0. I wanted to hear some stories from your guys point of veiw

 

Started spraying my 5.3 at 130K miles, ran 3X bottles of 100 shot through it, and a couple bottles of 150 shot through it. When I pulled the motor it looked perfect. Go for it. I was running 31 or 32*s of timing on the 100 shot and 93 most call BS but thats what Allen Nelson told me he had it set at. Dont know what it was at on the 150 a good bit lower I would assume.

 

just make sure you don't run any leaded fuel cause that will kill o2 sensors quickly.the only unleaded fuel i know of is 104

 

what kind of times did you guy pull with the 100 and 150 shots if any of you guys sprayed while you were stock heads and cam?
