Got the car dynoed today :(
<strong> Well I finally got around to getting on the dyno..mod's are as follow's..T.E.A S2 5.3 liter heads,comp 224/230 .568"/.573" 114 + 2,pulley's,SLP longtubes to ORY pipe,SLP loudmouth,lid,ram air,85mm maf,3200 stall,fernco coupler,ported TB,and other minor stuff..Well since the car wasn't tuned and has no ls6 intake I wasn't expecting too much..but wow I expected more than this! number's are 376.8 RWHP and 367.7 RWTQ</strong></font><hr /></blockquote><font size="2" face="Verdana, Helvetica, sans-serif">Are those numbers with the converter locked or unlocked?
I just read something that might be related, on the corvetteforum:

The number's are W/ the converter locked..I am going to give the X1 cam a try..my only problem is i'm a huge nitrous freak..I am planning on spraying 175 or 200 with this cam..and 125 or 150 with the X1 because of it's reverse split...I'm waiting to see how Jason99t/a's car will hold up on a 250 shot with a reverse cam...could be interesting <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> if it hold's..i'm going X1 with a 175 or 200 lol...later,

Yes I only measured from base circle to peak lobe though..so all it meant was the new cam has a smaller base circle.I was just freaking out because I wanted everything perfect lol..later,

As you can see, the exhaust [really] flows on these heads. I guess the intakes flow fairly close to most other Stage 1 heads, but again, the exhaust really flows exceptionally well.
Anyway, with a TR220 cam, LT headers with cats through the muff, LS6 intake, and an unlocked 2,800 converter, it dyno'd 375 rwhp without any tuning. Now, that was on AMSs dyno. Chris Marsh stated that there dyno is somewhere around 10-15 rwhp lower that most other places (who knows). Hope to dyno about 385-390 after Thunder plays with the PCM. Not bad for an A4 car with a smallish 220 cam.
Anyway, I think all you really need is tuning. Some of the big cam cars really wake-up alot with tuning (more so than the small camned cars)
Again, those TEA heads work well.
BTW, the 5.3L TEA heads will yield about a 10.8 to 1 CR if only surfaced .003" like mine. I would not mill them anymore if you are using pump gas on a daily basis. The reason the CR is below 11 to 1 on TEA's 5.3L heads is because they remove material out of the chambers in order to un-shroud the valves. 10.8 to 1 CR is real nice on a daily driver using your standard pump gas all the time.
Just my opinion
Ron,

The number's look great so the head's arent the problem for sure..maybe i'm just expecting too much though?because if I put the ls6 intake on let's say it add's 10-14 hp..if I got 14 from it that would be 390.8 RWHP...then i'd say a cut-out would be worth another 5 to 7 hp over the loudmouth..that would be 397.8 RWHP...damn I would be happy with that because that is awesome power AND a very N20 friendly cam...hhmmm I need to stop worrying and get a damn ls6 intake and cut-out lol..then on to the 4200 stall and so on <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> thank's for the support guy's..Except PHILL97SVT...dude you seemed pretty cool, but then you gotta throw in some doubt and try to flame on people, not cool man. but to answer your question..I was told the base circle is smaller on my new cam so the actual lobe itself was smaller than my stocker...later,

Are you smoking crack? You emailed me and said that you measured the cam lobes and thought something was amiss that the lobes were smaller. If your lobe equate out to a .500 lift than you found your problem. Loosen up. BTW, how is asking if you measured the cam lobe flaming? A low lift cam will cause lower power output compared to a higher lift cam.

just to give u a comparison:
with my 228/224 .588 .581 114 cam, I made
364 rwhp unlocked
381 rwhp locked
that's with a LS6 intake, ported TB, SY4000, 3.73s, and stock heads....and Edit, of course
Hope this helps some, good luck

No bro I was just in a bad mood yesterday,sorry...the peak lobe lift on my new cam "look and measured" smaller than my stock cam..but I didnt even take into account the base circle..the cam was measured with a dial caliper so it freaked me out,but someone pointed out to me that if the base circle is smaller the lobe will meaure smaller in overall ..ONLY with a dial caliper..if it was degree'd than it would be a different story because i would be measuring actuall peak lift..sorry to bust on you bro..just wasn't feeling so hot yesterday lol..later,
