Exactly what the title says my friends want to put a 150 shot on my car and i just wanted to see if that will hurt a stock motor?

 

That really depends on the condition of your engine.. lots of guys run a 150 though. Just make sure you take the proper procautions.. I would run a wet kit and make sure you have a fuel pressure safety switch, window switch, also aftermarket ignition with timing retard.... Also get some copper plugs 2 colder..

 

its in pretty good shape 102k on it plan to put 110 with 91 to bring up the octane. They have everything laying around extra except an aftermarket timing retard and i dont have colder plugs how important would those be. it is a wet system i wont run a dry system.

 

I wouldnt run spray without colder plugs or a timing retard at that level....

 

i think you should not have problems maybe plugs (104's), not retard.
i was runing 150 on stock everything 160 deg thermostat and 91 fuel, you want to use a window switch to prevent back fires.

 

It will go out eventually, but you can get it to last for quite a while if you take proper precautions.

 

Thanks guys i really appreciate it this is basically a one time this weekend until i get some more stronger stuff. It might make it to the track once more this year but rihgt now its still my daily driver so for now just this weekend.

 

Make sure the 110 octane fuel you are going to run is unleaded.

 

When I was spraying I was running colder plugs. Crap still have cold plugs.

Colder no timing retard. 150 shot on the dyno. Held fine, but only went through two bottles.

 

if you arent going to spray it every chance you get, or only spray it when you go to the track ever so often, all the extra precautions wont be something you absolutely have to do. id reccomend a window switch and afterarket ignition system such as a crane or msd box. definetly go wet kit at a 150 shot.

 

You should see a big difference at the track... keep us posted on times. My buddy is sprayin his stock LT-1 about 150hp wet and runnin' mid 11's. Good luck!!

 

how bouta 305 tpi...i plan on swaping it soon, how long u think it will last, runs great now. 70k on it. also does any1 no were i can look to learn more about a window switch??? what is it for exactly?? thanx

 

that really exist? 110 unleaded? who make it? and how much per gallon?
i thougth that the maximum octane for unleaded was 104. I'm using from Sunoco
