Something that I have addressed and continue to address.


If he said I need a setup to dominate the road course.. I would not even bother postings as I don't road race in general. So maybe a pdb only bolton is the winning scenario. I merely point out that this is a huge heat load on the LT1 and this will cost a heck a lot more than a AFM cam and tune.

Now let me address mid-range, completely off-topic for the OP, but I'd spec a roadrace cam depending on mods as something like 226 / 234 with a 112 LSA installed straighup.
The LSA would bring a huge chunk of midrange power.

He can't hit his goals with a AFM cam.

My bad then.

No. That was for the OP to consider before he goes down the rabbit hole with modding his car. Pretty obvious I thought.

I've already noted the biggest benefit of FI is the ability to have a stock exahust or at least one that is not bruttal.



Great, thanks for the information and I'll add in the OP said 500+ WHP so that makes his list too. The Lingenfelter cam is a lot milder than the comp AFM cam.

Given the OP parameters, the big comp AFM cam, RotoFab, ported TB and manifold, E85, cat back, tune could very well make 500 WHP on a dyno. Nowhere did I say what he wants is optimal. But you contend that it is not doable. And yes he said 500 WHP up... not your can't reach 530 WHP.

So cam only longblock stock header maybe cat is it plausible to hit 500 WHP...probably so. Is it smart or cheap, maybe, maybe not.




The Maggie + tune adds weight and heat, he reaches two of his goals, maybe his other goals on the CAM CHANGE THREAD of the goals is to not add heat and weight to his DD, once in a while road race car. Plus the Maggie + tune is a one time expense that is probably a whole lot more than say he does a cam and tune only which reaches many of his goals including lope. Maybe the huge savings in both weight and expense and heat load is worth it to him. Maybe he wants to do headers and cats down the road and pay for the $110 going rate for a re-tune. Clealy and once again the PDB is not what he is asking for and that $6000 up probably a lot more if the shop is going to do it, is a lot more than at a minimum say +$1000 DIY cam and tune. The install cost is close to the same.

Face it the bolt-on maggie has little place on this thread as it is addressing NOTHING the OP asked for.

Let me address this 530 WHP, here is the OP:



the biggest comp cam probably will yield both. You just pushed 530 whp as you knew it would greatly undercut your case that a PDB is the best solution.

Ok so here you are preaching this AFM cam when nobody runs them for a good reason. Factory AFM lifters are worse then LS7. You had a failure with LS7 lifters with your build but you are suggesting a AFM cam?

2 guys just posted builds that barely made 500whp with headers, one had stage 3 cam, the other had heads and made 520whp. A AFM cam only setup on stock exhaust wouldn't make more then 470whp. It would be lucky to make the power of a FBO car.

I didn't under cut a anything, the OP said 530whp.


The Maggie is a far better solution then a AFM cam that is FACT. 7 psi is barely working a 2300 so heat wouldn't be any issue. The added weight could be mitigated elsewhere. That is the only reason why I agreed with another member that suggested it first. If the OP was willing to approach the NA build correctly then I wouldn't of mentioned a blower. Anybody that thinks rationally can see my POV on this.
