This is not that old a setup, I received the heads last December and had everything installed by February. What's the best way to get a hold of Nick? I tried calling him a few times but he doesn't pick up the phone and his mailbox is full. Should I just send him an email? Tell him to take a look at this thread?

Any ideas about the installation? I know it's tough to say, but is there anything that could have been done wrong that would account for missing 30-40RWHP? As you can see from the dyno graph, the car feels great, smooth. No PCM codes either.

My set-up was fairly new and was supposedly an upgrade from his previous heads. My times are decent, so I haven't worried about dyno #s too much, but I do know others on the same dyno have put down well over 400 RWHP and Nick himself thought I would have seen another 10HP or so. Nick has offered to work with me on the cam issue, so I have no complaints with ARE. I just haven't decided what to do. Going over 224 starts to get tough when emissions testing could be an issue.

My .02 worth from <img border="0" title="" alt="[Roll Eyes]" src="images/icons/rolleyes.gif" /> reading <img border="0" title="" alt="[Roll Eyes]" src="images/icons/rolleyes.gif" /> about ARE and other set ups for the last four years. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

First

Are folks with ARE heads that are disappointed, sure their transmissions/clutchs aren't slipping? A slipping transmission/clutch could easily eat up 20-30 or more rwhp. <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" />

Second

I thought it was generally reconized that ARE Stage 2 heads were more race only oriented than almost anyone elses. I've heard it said many times ARE Stage I's are equal to most others Stage II's. Likewise, an ARE Stage II head is set up more like someone else Stage III race only head might be. In other words, one would expect ARE Stage II's to be hogged out heads with big valves to work with big cams. Nick always said most people don't use enough cam in his opinion. His set ups that make power seem to take 226/234 as said before.

If I had ARE Stage II's I'd try a proven ARE cam because ARE heads are probably matched to work best with ARE type cams...big split duration cams. If the power was still low with ARE Stage II's, ARE matched cam, tuning, and a solid transmission...someone should be <img border="0" title="" alt="[Embarrassed]" src="gr_emb.gif" /> and I don't mean the car owner...

Third

Looks like more than one ARE Stage II heads and non-ARE cam set up is making about the same power as a good well tuned cam only set up. <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

Anyone with disappointing results game for putting the stock heads back on with good springs and seeing if the power is about the same with a cam only as it was with the ARE Stage II's and non-ARE cam?

Fourth

If passing emissions are an issue, I'd look to other proven set ups than make power with a small to medium cam. <img border="0" alt="[Fluffy]" title="" src="graemlins/fluffy.gif" />

and last

If the heads really flow, have good velocity and are ported with that in mind, they don't need a big nasty cam to make excellent power. <img border="0" alt="[angel]" title="" src="graemlins/gr_angel.gif" />

Isn't that about what a good Stage II head should be worth?

I expected to be in the 40 - 50 rwhp range. Like I said, Nick thought we'd see 390, maybe a bit more. Heads are a pretty big investment to leave 10 HP on the table.

Having raced with Dave Potter (OnyxSS) I know Nick's stuff can perform, just the big valve set-up may like a different cam. <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

Default Re: Poor dyno results on Stage 2 heads and cam, what next?

I was wondering the same thing.. The cam theory with big valves.. This thought has crossed my mind many of nights after my setup was back together.. Is my car under cammed for these heads or like I have said before, my heads are not performing as promised. I have 2.08x1.60's on 5.3L heads. I have the 226 XE-R cam.. Could it be my cam is not giving me enough charge up top for my valves? How big should I go to find out?

1) My clutch only has about 6000 miles on it, and it's not stock. And there's no slipping on the N2O, so I don't think it would slip on motor.
2) Sounds like that's what people have been saying.
3) If I was to replace my heads only, would I still need to pull off the crank pulley? Because that's the major pain, I'd have to remove the steering rack to just get to the crank pulley.
