With a blower car i'd keep the 2.055 intake and try to put in a larger 1.625 exhaust valve. Since blowers build boost linearally and you dont get boost as soon as a small turbo, the larger intake valves will have an effect on non-boost driving, ie driving around half throttle and tip in etc
BOS, that cam will work but it wont be optimized. If/when you switch to more of a blower specific cam you will should see a LARGE jump in power

Re: Going to order D-1SC tomorrow, help with the checklist... I might consider switching cams now...
But probably not..
What would be the most ideal supercharger cam?
Something like a 226/230 .571/.591 114lsa?
Also, any idea of what kind of actual boost I will see trying to run an 8lb setup??
Thanks,
Bos

Re: Going to order D-1SC tomorrow, help with the checklist... basically whatever ATI rates the pulley setup you have now and minus a few PSI for your better cam/heads.
Your cam is going to dictate on your setup. Meaning your intake/exhaust cfm ratios and your exhaust setup as a whole:
ie header...y-pipe...true duals...mufflers...etc
if you have good exhaust flow on your heads you wouldn't need a large split. If you dont, a larger split. All depends on the COMBO...

Re: Going to order D-1SC tomorrow, help with the checklist... Well here is what I have besides the other things...
MTI S2 heads, (stock compression) 10.3:1, 2.055/1.57 valves...
X1 cam
FLP long tube headers, running through off road pipes, then through a dual-dual, I also have a cutout, so that will be open at times..
So I actually could do something like the X1, just flipped around, on a 114lsa...
TTT on this
Also, any idea how much you could sell an X1 cam for w/1000 miles on it?

Re: Going to order D-1SC tomorrow, help with the checklist... Yea, the summers are great around here, I wish it would be like that all year round, even though it can get damn hot around here, almost too hot in the summer... <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Re: Going to order D-1SC tomorrow, help with the checklist... "Fear the LS1 F-bodies..."
Why? <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
As far as a cam, I would suggest-
Intake
212 @.050 .530 lift
Exhaust
218 @.050 .545 lift
114 LSA 112 ICL

Re: Going to order D-1SC tomorrow, help with the checklist... Would that mild of a cam work well with the setup...
I was looking for something a little more aggressive...
I had a few ideas...
226/230 .571/.581 114lsa
227/230 .571/.591 114lsa
224/228 .581/.591 114lsa
Few others, I want to stay with these sort of aggressive cams, unless they aren't practical..

Re: Going to order D-1SC tomorrow, help with the checklist... IMO, your better off without an "aggressive" cam for a supercharged application.
226/230 .571/.581 114lsa
227/230 .571/.591 114lsa
224/228 .581/.591 114lsa
All these cams, even with a 114 LSA, have alot of overlap due to the amount of duration.
I think it would make alot more power with the cam I recommended (or something similar).

Re: Going to order D-1SC tomorrow, help with the checklist... Thanks for the help jim, after all, you are the tuning god, I'm sure you've seen a lot of combos, and also you have a S/C car... <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
Also I want to look into the future, I have a problem with changing my mind a lot, I know I will probably build the bottom end in the summer after I pay off the blower...I will most likely stay stock cubes....but built for boost...
So the 212/218 .530/.545 114 lsa is something to look into....where would I start to hit the point of loosing power because the cam is too aggressive...
212/218 seems small....but maybe thats just because I'm used to running N/A cams...
Would something like a...
218/224 .550/.565 114lsa work just as well, or are we looking into too much over lap with the duration and lift #'s...would this cam make less power than the one you suggested?

Re: Going to order D-1SC tomorrow, help with the checklist... Bos, I would stay at or under 220 on both intake and exhaust. After experimenting with Jason's car it seems that going much past the 221 duration mark even on a 114lsa does more harm than good.
Jim, what would you think of a 216/220 on a 114lsa?

I think that cam could work well, but not as well as a smaller cam. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
Just for comparison, the cam in my LT1 is-
214/222 .531/ .542 113.9 LSA
After having it in my car, I would have went with something smaller, because it made peak HP higher than I expected (6,100).
I'm now switching to turbos, and my new cam will be something like-
212/208 .525/ .510 115 LSA
From what I've seen of blower LT1/LS1 cars, the smaller cammed cars tend to impress me more. I think that when you have a very good cylinder head, you don't need alot of duration, and having very little (or no) overlap is of more importance.
BTW, I can't wait to see what your car will do launching off the transbrake on boost <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Re: Going to order D-1SC tomorrow, help with the checklist... Hmmm, this is starting to get interesting...
I need to make a final decesion on it, Jim, how much do you guys charge for a cam install $300?? I forgot...
So I want to stay with small duration, small lift...
Any more cam suggestions Jim, list as many as you want, I need to pick...car goes in on the 18th, and the way its looking I will probably order a blower cam from you guys in the next few days...
It will be on Nittos Jim....Rev limiter City... <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> But you can watch ME do it at the track... <img border="0" title="" alt="[Razz]" src="gr_images/icons/tongue.gif" />

Re: Going to order D-1SC tomorrow, help with the checklist... I basically want the ULTIMATE blower cam, the most efficient, will make the most power....

Re: Going to order D-1SC tomorrow, help with the checklist... In my opinion you want to stay with small duration.
Small lift isn't something you necessarily want, but you can only have so much lift on a lobe with a certain duration otherwise the lobes get to aggressive.
If you want a few to choose from-
208/216 .520/ .540 114lsa 114icl
212/218 .530/ .545 114lsa 112icl
214/222 .540/ .550 114lsa 112icl
216/224 .544/ .554 115lsa 111icl
Just some ideas.

This one caught my eye....
Where would I be peaking w/this cam?
Jim how much do you guys charge for a cam install...???
