So as you guys have known i have been doing my research on cams and well here is what i found out.

N/A DD: The winner is the best all around cam is the are the XE274, you lose low end power but gain high end power. They will scream like hell in the mid to upper RPM range. In second place is hitech Stage 2. No low end loss great high end. 3nd is CMS stage 2, but this is debatable because the torque and HP is similar to hitech but the reason they lost to hitech to me was because hitech favors intake. There for it won second in my books.

N/A with Nitrous: First place is the XE274, It favors the exhaust side more. Second place with out a doubt, CMS (VT) Stage 2, and finally Hitech stage 2 in third. Nitrous motors tend to like a lot of exhaust flow, since the nitrous adds all the necessary intake oxygen molecules. All that improved intake efficiency must now be allowed to escape, thus the need for greater exhaust port flow and wilder exhaust cam timing.

F/I: I didnt put the time or research into them.

Remember this is all MY OPINION on my research that i found.

I have came to my conclusion, and i will be getting the Comp XE274. But what i do want people to understand is that the XE274 is a huge cam. It will affect performance for DD. But it will scream like hell in the mid to upper range.

Specs:
CMS Stage 2: 225/235 Duration @ .050" Lift, 108 LSA
Hitech Stage 2: 234/230 Duration @ .050" Lift, 111 LSA
Comp Cam XE274H: 236/240 Duration @ .050" Lift, 114 LSA

Enjoy.

 

you didnt check out crower?

 

Crower cams are weak compared to the other cams. Their stage 2 specs are 220/224 Duration at .050.

 

Alright so I want to get cams in the future. My car is DD and I really just want something that lopes as hard as possible, sound good, and give a good power gain. Now, I have been doing a little research and I think stage 1's would be a better application for my car. It will just have your basic bolt ons such as exhaust, tb plenum, intake, etc. What do you guys think about them? Will I regret doing stage 1's in the future? Reason for 1's is that I wont have to change springs, etc. I like the way Comps sound much better than the idle of CMS.

 

If you want all the effects of a big cam without the big cam numbers.. cams are not for you. The only way to get the sound of a choppy cam is to..you guessed it.. get a big cam. Stage 1s are good for about 10-15hp thats about all.. if ur gonna get cams get stage 2s and gears.

 

So do the comp 274's have more power gains than the Hi-techs? I've been wanting the hi-tech's because I heard with bolt-ons can get me to or alittle over 300rwhp with no low end loss (I heard the power band is almost the same as stock). But I don't mind losing a little bit down low if I can gain even more on the higher end with the Comp

 

Hmmm ok. So if I was to go with the Comp stage 2's, I would have to and want to get cam gears and springs, right? If theoretically I was going to do this in the summer, what would be the ideal setup and costs?

 

Word on the street is you dont need cam gears. all u need is the cams and springs. Supposedly gam gears arnt really needed, and they make the install a PITA.

you would need a tune after the stage 2 install. ur looking at around.. 600 for cams 300 for springs 200 for a tune? and if u cant install urself..tack on another 400ish

 

I'm picking up Hitech Stage 2 cams over the summer. The dyno sheets, 1/4 mile rumors, and sweet lope at idle is what sold me.

 

Everyone that I know with them are at or over the 300hp mark.. Hi0techs are no joke... theres at least 3 or 4 ppl in san antonio with hitechs
