Was just wondering if there was anything i needed to change in order to switch from a 150 shot up to a 200. Less timing? Cam timing? Other than the obvious fuel and n2o jets! lol Probably try a 175 first then if it survives that make the jump to 200. I figure what the hell,im gonna try it. Seen a number of guys doing it on stock bottom ends. Any changes needed?

 

pull a little spark advance out and try it. Hope your fuel system can keep up.

 

what should you be using fuel-wise on a 200 shot? maybe a progressive controller if using in first...

 

FYI i had a 175 shot on my cam car and it made 200 rwhp and 300 ft lbs.


and i maxed out a single walbro in tank pump too.

 

For a 150 shot do you have to retard timing? and how much should i adjust my plugs to???

 

What kit do you have? Sounds like direct port. You maxed out a 255lb pump? Thats what i have.

 

Stock timing is OK, get colder plugs gapped around .035-.038

 

TR6 plugs should be good right?

 

yes..

 

i was running a standard NX wet kit....you can actually see the dyno where the A/F started to rise slowly in responce to the fuel pressure dropping.
