Heads/Cam, 100 shot, and pump gas?
 

Hey fellas.

Just have a quick question. Currently plan on putting heads on my cammed car and also spraying a 100 shot (dry) on top of that. With the heads my static compression ratio will be around 11:1. With that high of a compression will I be able to spray on pump gas (91 octane here in CA)?

I do plan on upgrading my fuel system to support the added power so I should be OK in that department.

Thanks for the help. :)

dont think it should be a prob,more will chime in on this,i say spray away,hope this helps

what size cam ? as long as the fuel pump/injectors is up to par you'll be fine, you might have to back the timing down a little tho

I have the same issue, I only wanna spray once in a while when I'm out on an open road, but dont want to drive around and waste my race in the mean time, I would like to use 91 octain pump gas over the expensive race gas but dont know if I should or could with a 100 shot, Maybe I could find a octain booster forumla.

11:1 compression with only 91 octane? I went with 10.5:1 to be safe. I spoke with a few sponsers on this site and everyone of them told me not to go to 11:1.

I would fill safe running a 100 shot with 10.5:1 but not 11:1

Just my input.
