My goal for my new setup is to make some nice low end TQ #'s, while still making some serious top end #'s. These 440 rwhp graphs that makes 350 ft lbs of TQ at 4000 rpm's and doesn't make over 400 rwhp until 5500 does not impress because that car is a DOG down low without some stump pulling gears. Now 440 rwhp, while making 400 ft lbs of TQ at 4000 rpm's would be a bad *** street ride. The question is which cam can do it? Lets just say this cam is paired with a GOOD set of Stg 2 heads....

A couple of pondered choices are as follows...

232/236 .590/.601 110+2 XE-R
232/232 .595/.595 108 XE-R
228/234 .571/.585 111+3 XE intake, XE-R exhaust

I want as close to 400 rwtq as possible, while still making 430+rwhp. Spinning to 6700 or so if fine. The setup will have good tuning, and heads.

Any info/suggestions is appreciated. I am trying to get my parts-ordering saga finished so I can wrap this thing up <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Just FYI, I'm making 391 ft-lbs with stock heads and the F1 cam. 403rwhp also.

This is a graph of the test car, but they have a couple of other cars getting this setup pretty soon, so we should see some follow-up results within a couple of weeks.

 

Josh, just dyno at MMS or Cartek and i am sure you will get the numbers you want with any decent setup...

Every GTP heads/cam setup we have recommended without cats and all the bolt ons have made 430+rwhp and 400+rwtq easily. One thing you should cond\sider josh is that with the cams yours looking at...bigger isn't always better. Your going to loose an assload of torque with the cams you have listed and they are going to be pretty peaky.

 

My buddy Micah made 447rwhp and 409rwtq with AAP stage II 6.0 heads and an AAP custom 230/236 .595/.595 111 LSA, idles like a champ on the street too. This was thru mac headers and a single cutout. Pretty good #'s if you ask me.

 

That's mainly why I kept the LSA's down, to try and move the powerband down for more low end power but still trying to retain big duration HP....

 

FWIW I run a Cartek S2X setup consisting of S2 LS6 heads,224-224 573-573 113LSA,LS6 int,LT's,and Cartek tuning.

My RWTQ # is 380@4000 rpm
My RWHP # is 400@5300 rpm
Looks pretty good to me considering its an AUTOMATIC?
Its also run 122+ at 3500lbs.

tight lsa's also give peaky powerbands...not just low ones.

keep a traditional split for big torque.

226/232 or 236

228/232?

both on a 112 +4

If you want good lowend torque, don't even bother with intake durations greater than 226 on an XE-R lobe.
