Some respected old school tuners claim 1PSI = 11WHP.

 

that .9 psi variation might not have occur where peak whp is on the graph, so it wouldn't matter if you were looking at the gain at peak whp between the different housing.

 

Any testing on the eBay headers VS megan VS those high-end (450-600)headers? I figure the ebay headers are chinese made as are the Megan ones.

 

It is an inconsistant test. It shouldn't be that hard to level the playing field.

Non-the-less I am done dicking around in this thread. DB thanks. To the rest good luck with whatever route you take. Odds are on the average cammed EVO it won't matter which one you go with.

 

Guess I don't understand what you mean? It sounds from you previous posts that you think Works has better fit, finish and reliability, yet here you say it is a moot point.

You are correct, these 3 topics are a moot point. Fitment - neither unit (SSAC or Works) fits any better or worse than the other. Finish - how can you tell me grainy cast iron looks better than polished stainless steel? Reliability - only heard of 1 out of many hundreds of SSAC units sold that has cracked.

So the only distinctions are the SSAC unit looks better (subjective), performs better, and cost up to 1/9th the cost of the Works unit (picked mine up for $50).

thanks for another honest comparison test.

 

the invidia would be impossible (nearly) to install on the car, the fitment isn't 100%, and the gasket needed turned around.

that being said, i'd put it on again, just due to the bottom brace, as i ended up with a cracked header for whatever reason, and swapping parts sucks.

 

You are wrong and not looking hard enough. There are people on this board who have had them crack.

The 02 housings that are made in China also can't accept the stock heatshield. You stick with Ebay, I'll stick with Works.

 

THere are? Maybe you could find more than 1, because I couldnt.

 

At least one has brocken, and maybe there are more. He was saying that number was ZERO. All I was saying is that his number isn't correct.

 

The fit/reliability are moot.

Finish is subjective, I like the cast (coated) piece from WORKS, if WORKS offered it in a polished or SS finish without compromising quality, fitment, and reliability that would be even better.

They all make at least 10whp more than a ported/coated stock o2 housing.

Buy what you want, I'll pay a little more (not a big deal for me) for at least a better fit/reliability with a modest gain. I have yet to hear of any fit/reliability issues with the WORKS o2 housing.

 

Dave, valid test and thanks for the work done. That couldnt have been an easy test, and I know I got on your *** about the 2.5 to 3 inch thing. Your right, the difference is minimal and I give ya the nod. With the same boost, they may have made the same or more. They may have not at peak hp. Who knows. The moral is, theyre ALL good parts. Pick the one thats right for you.

As far as the guy that said the fitment of the ssac is the same as works...I wouldnt agree with that. Fit to car on ssac is great, but lack of bracket for heat shield loses points. Id give works the thumb for that, and ssac the thumb for more whp. But thats just me.

 

Not blowing hot air @ 34psi on an overworked turbo!

Funny you mention that. Dave has got to be one of oldest, respected 4g63 tuners around yet you choose to contest his testing method. All you are doing is trying to justify your poor ratio of cost vs return ratio on the O2 you have chosen.

We don't always agree on all subjects, but we do respect DB's tenure and credibility. Show some respect. As stated, DB would not give a **** if another 02 outperformed the standard O2.

 

This is exacatly the reason that DB says to use a stock ported Manifold over all but the Full Race. If it was solely about making money he would sell you both SSAC parts. (Their tubular manifold and O2 housing)

Bottom line is this test is better than anything else out there. If not anything else repect that because the proof is in the numbers.

Although next I would love to have him test an XS Power FMIC vs stock vs their delux or RACE kit. That would be in interesting showdown. Also a stock crank pulley vs an Ebay pulley.

Most of the info you need on the SSAC/XSP intercooler is in that thread. It has been tested independently by a couple forum members, but that was just logging road runs. Testing on the dyno will probably give the whole story as to it's potential or lack thereof. However, I don't think Buschur should waste his time with it. It is a "copy" of the AMS IC, so I feel AMS should be doing the testing to disprove it's merits. I don't think they are interested, though.

The crank pulley is an interesting proposition. I have heard good and bad. The good is ususally from someone who put it on and made a few more HP on the dyno. The bad is from engineers who talk about crankshaft harmonics and how without the proper weight dampner on the end of the crank it will oscillate at certain RPMs and over time beat the he!! out of the bearings, or worst case scenario, the crank will break and take your entire engine with it.
