Thumbs up Review: 473 rwhp Mike Norris Motorsports cam


 
Video of idle: http://img541.imageshack.us/img541/6382/sam1716.mp4

Okay I really didn't know about Mike Norris Motorsports until after I setup an appointment and then weeks later, my girlfriend and I go to LS Fest and visit the Wiseco, Comp Cams, and GMPP manufacturer's tents. There, just a couple days before I dropped the car off at Mike Norris' Indy shop, I was completely allayed of any fears by each of those representitives talking about how good Mike Norris' work is. So as a mechanical engineer who struggles to let ANYONE touch his car, this was great news.

The pragmatics of a cam install situation are that if a tuner has been installing the same cam with great success for years, then obviously he's got the computer tuning down pat. Even the Wiseco piston guy said Mike would already have HP Tuner files, massaged for the past few YEARS already on LS3's, that would get him 98% to a complete tuning solution. Far quicker than I could do on my own, and of course as an engineer, I will likely break something along the way, hah! So I bow to experience.

What initially clicked with me and Mike was that after I scoured the various Corvette and other LS-oriented forums (as C5 is somewhat lacking in depth and consistency for hardcore LS technical content due to it's youth), I found that a cam around low 220's on the intake with an overall overlap of around 2 to 3 degrees (@ 0.050) which would correspond to an LSA of around 114-115 would be an excellent compromise between a NA or FI setup. Since my goal is a Whipple before next spring's racing season, these cam characteristics are what I felt were appropriate for my goals. In one of Mike's initial PM's with me, he stated he'd been using a 224/236 114 LSA cam for several years with success on Magnacharger LS3 cars.



The previous setup:
  1. Stainless Works long tube headers (2" primaries),
  2. Catless, 3" exhaust, 4 Magnaflow mufflers (2 round, 2 oval), Tru-x xpipe,
  3. AEM in-the-fender cold air intake, Spectre bellmouth, SaxonPC flow straightener,
  4. ******* tune
Mike Norris Motorsports work:
  1. MNM custom cam (224/236 114+4),
  2. Dual valvesprings, lightweight retainers, moly pushrods,
  3. VMax CNC ported throttle body,
  4. Dyno tune (with Mike's mature LS3, well-tested HP Tuner work)
Dyno history, all Dynojets:

370 rwhp - stock, in FL (Adam's Automotive, Crestview, FL)
412 rwhp - previous setup, in FL
402 rwhp - previous setup, in IN (MNM, Indianapolis, IN)
473 rwhp - Mike Norris's work


Now for those about to talk trash about dyno differences, the FL numbers are SAE, so maybe the altitude difference is a bigger player...about 450 ft is my guess.

Qualitatively, I cannot begin to describe the superlatives of this install: drivability is almost stocklike, on the throttle, outsiders are treated to quite the cam'd car symphony, and of course, at idle, the lope, especially on the outside, is just pure music . If anyone in the panhandle area wants one for their Camaro, I'd certainly be willing to let you hear/see the one in my LS3.

473 rwhp...nice! Thanks again Mike!

I thought Mike said 8 rwhp realistically for the Camaro with Corvette LS3's gaining a little more, but he can comment on that. For $150, that's 8 inexpensive rwhp.

Yes, the tune, and maybe a throttle body...you've certainly got more duration and lift, and at that LSA, you've got more overlap as well. Is the cam advanced or straight up? What timing and AFR are you at?

Edit: I saw that you don't have a cold air intake, so there's that as well. Sounds like your 453 is about right then. Only thing left is to...SPEND MORE MONEY!! LOL!

I drive up from Florida to Indiana several times a year, and in a few months am headed to California for a couple months of work, so being in a 110+ db metal box for 20+ hours is something I want to avoid. Working around aircraft engines for a couple decades puts me in the frame of mind of not acquiring tinnitus from the workplace, so acquiring it from my own personal vehicle would be just plain stupid. Even with the extra mufflers (but no cats), it's still ALOT louder than my coworkers Borla S-type catback which is oddly ALOT louder than a SLP long tube header w/3-inch catback system I've heard locally. Just wait till you get a ringing in the ears that won't seem to go away....
