speed density?

[new 2 tha game]

Does any one know what all i can do with my car without having problems because of the speed density?

You can do a lot of mods to the engine as long as you don't mess with the cam too much. There are several grinds that will work with SD but the computer is very sensitive to a change in the vacuum signal. Some people will tell you that you can't mod a SD car, but there are a lot of guys out there who have done it successfully. Including intake, heads, and even superchargers. Most of the basic mods are fine pullys, cai, tb, headers, etc. Hope this helps some.

agreed, there have been many in depth threads on this, mostly in 5.0 talk, as i recall. the die hard S.D. folks have done some nice stuff and know what works and doesnt. they had detailed posts in these threads.
keep the s.d. it has better power than maf stock vs stock. mods do work. dont give in.

Is it impossible to change the cam at all or do i need to be real cautious

 

[HISSIN50]

you can swap it, you just need to be cautious about how radical you go. we have all heard cars with a barely streetable, lumpy cam, and that will not work (ones that need a vac canister to assist with brake booster, etc). but you can get some decent cams that work just fine while retaining s.d.

I've read that the cower 15511 is a good cam for my car but i would like to hear form someone who has it before i buy it.

You can use any cam that has a lsa of 114° and duration @0.50" of 220° or less with speed density. I have heard of a lot of SD guys running the Crower 15511 with no problems at all.

I know the crower cam is a little bit pricey i was wondering if any other cam worked just as good for a little less price

 

[ComfortablyNumb]

Just find any cam with a 114° LSA under 220° duration @ 0.50". But the Comp Cams xe264hr, nx264hr, and xe270hr also work with SD.

I ran the 15511 with SD in my old 302 yrs back with heads, ex, int etc etc and worked great.. has an excellent TQ band with good power to 6k.


Hope this helps,
