went from MTI Stealth II cam (224/220 581/581) to MTI X1 cam(230/227 591/571) was expecting 20 to 25 rwhp gain only got 4 rwhp gain WTF ??? DOES THIS SOUND RIGHT ...

A 224 to a 230 isnt going to net 20+hp. In fact I put down the same numbers with a tr224 as a 230/232. +4 seems a little low but not incredibly low

I think you need to look at the different graphs and different powerbands in general. In portions of the powerband you probably gained more than that, peak numbers don't mean anything too terribly important. The curves should show a bigger variance than the peak numbers

I'm also guessing that your on stock heads, if you upgraded to a better flowing intake and head I think the difference would be more apparent, I don't know anything about your setup so it's hard to say whats really going on but I would think you should net more than 4rwhp, let us know what your setup is

i agree with all of the above.

the stealth cams are designed to sound and drive stock. which means they probably make peak power high in the rpm band.

the 2nd cam will likely produce much better low and mid range power, but may not make all that much more peak power.


EDIT...

just saw your mods posted.

can you run 1.8s with that cam?? or are you listing the lift with the new ratios already changed?

Wrong on both accounts.
1.The larger the cam the more latent the power. Thats not stock.

2. The larger the cam the more peak but less torque and down low power

Your backwards

LOL I love to see thread like these, but it is simply a matter of VEs and lobes.
The Stealth XE-R is more agressive.
That is why i'm not a big fan of bigger is better. As stated though the graphs should have different powerbands. COLONEL StealthII is a tricky little bastard.
I've been 11.23 @ 122mph with a high compression combo on a 346 with that sucker.
Just to add fire, I just went 10.96 @ 124 witha 12:1 370cid and a small 224/222 117 LSA cam better NA than the same combo and a 232/234 113 LSA

what was Point #1 refering to? not sure what you mean.

as for 2....i see what you mean...but if you read what i wrote i was insinuating that the stealth cam (224/220 on a 116lsa) will likely make peak power high in the rpm band.

while the X1 has higher duration, it also has a 112 lsa....which should bring the power peak down in the rpm range...and at the same time i would think make a little better mid range.

i may not be dead on...but i not "wrong" right?

No your wrong to say what you said the way you said it. There are things you can do to a big cam to make it act better, but the bigger the duration the more latent the power. The 112 or 110 lsa will be more peaky than the 113 or 114 lsa.
