Default Pushing the cam limit. What do you think is possible

I would LOVE to see someone try out the new XE-R based cam with the following specs and LS1 edit tuning.

230/230 112LSA and .59x-.600lift intake and exhaust.

That with a 11.2:1 S2 head with double springs, LS6 intake and adequate PV clearance (Not sure if you would need valve reliefs in the pistons or not) would make one awesome performing combo.

It would probably make a little more power over the MMS 229 based cam due to the even more aggressive ramp rates of the XE-R lobes. The 112LSA would keep the peaks reasonable and boost midrange torque over the 229 cam as well.

Imagine that combo with a 4.56 geared M6 or a 4.30 geared A4 on slicks. Would be impressive to say the least <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
Someone please try it haha!

Ron Anderson has just come out with a few grinds of hydraulic roller cams that will rev safely to 7600 rpms with factory ford hydraulic roller lifters. The key is the ramps and the valve springs. I would bet the cam lobes are similiar to the XE-R's but the valvesprings are key. It shouldn't be long untill those springs trickle over to our LS1's. Then we could see some serious #'s from built stock cube motors.

Nah the 229v2.1 cam is already perfect. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Chris, why didn't you try that since you just finished a cam swap? <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

I agree it sounds interesting, though... Big cams are cool <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

Its not far off from your current cam.

hahah, my car just got put back together though <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
I want to get some results from this cam first. Besides, I am pretty happy with how it is working so far <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

based on what Mike Morgan told me, the 229v2.1 is a fairly fast ramped cam. They did this to shorten the adv duration so the idle quality improved somewhat. but that big of a cam on a 112 would be a rough idler...

I sold the second cam to Nick, not sure what he did with it. Had split lift on the intake side to hold the intake valvas open a little longer.

PSJ, That looks like Extreme energy lobes not the new XER lobes. I could be mistaken on that though.

LOL XE are extreme energy.
The XE-R lobes are another extreme energy lobe with different ramp rates <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

PSJ did you try that 2nd cam before you sold it to Nick? I would love to know power and idle info on it. TIA

Seriously, I don't know the exact specs yet, as Nick came up with it, and wasn't 100% sure what the final numbers were when I talked to him yesterday. However it is smaller than what he and I initially discussed for some reason. In the back of my head, I can't help but worry that it won't make peak power/rev where I want it to with the smaller specs, especially when taking account for valve lash.

It is a mechanical roller cam, BTW...

LS1derfull, the cam idled fine, and was a lot of fun. I had a chronic problem of blowing head gaskets, so I ran a 11.6 with the cam with low shift points... Never dynoed it.

Solid roller George or Hydraulic?
I would call Nick and tell him you want the XE-R 230/230 .59x lift 112LSA cam <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
You can get it to idle with LS1edit and it would freaking SCREAM.
Are you getting valve reliefs in the pistons?
Cheers,
Chris
