Trying to figure out a good setup for next year I was planning on just getting the prc 227 heads,I'm still gonna go with those but I have to wait a lil bit to get those,the new rearend ,rebuilt t56 is setting me back a lil bit and on top of the holidays it will be later spring till I can drop over 2gs on heads,so I was just thinking of spraying it ,maybe 100,125 .my car is a 99ss m6 full bolt on ms4 cam,intake will be a ported fast 90.just thought I would ask how the ms4 runs on a 125 shot,or what kind of times are you getting with the ms4 and spray

 

Ive sprayed my ms4 up to 150, and it seems to take it pretty good. I was low on bottle pressure (800) and I was able to knock off 6-7 tenths in the 1/8th with mine. 7.0@98mph with a 1.5 short time. Im on a stock 10 bolt with 3.23 and an ls6 intake. With a lil more bp I think I can in the 6's. My kits dry as well. Its not a 125 shot, but maybe you can use a little ref. From what I have "heard" It's not a great cam to spray over 225hp. Idk why but that's what I was advised.

 

I was only gonna spray 100 shot, I'm changing to taller gears when I get my new rearend,I might just see how that does,with the stock gears its not to bad down low but its not great eithier,we do a lot of roll racing around here and from a 40 roll my car pulls pretty hard,but I'm trying to get the most out of the ms4,just wanna get something running pretty good till I can start on my 6.0 turbo build

 

Well if you can compromise with mother nature, and all the wonderful drivers out in this world, start pulling all the safety stuff off, and ac and junk. There is a lot of expendable weight to take off. Just another thing that lets us take advantage of every ounce of hp. My car right now weighs 3200 without me in it, ive still got carpet and heat, and stock elec leather seats.

 

should be 10s no problem on a 125-150
