I saw one of the H-T members selling one and so I went ahead and checked it out on their website. It's a 4-1 design, 2" primaries, 2.5" collector, mild-steel built, mandrel bends for $480 shipped. They have option for ceramic coating for $150 and SS for $230 extra.

Have anyone used these headers before? If so, anyone have a dyno to prove the performance gains of this header compared to others?

Actually I think that there was some dyno number on H-T

but they dynoed the header on a stock b16a motor - It showed pretty

decent gains-

I would really like to see results of a high comp b20vtec
so you make the comparision with hytech and smsp header

2in primaries, in a 4-1? Jesus! Can you say 27hp until about 5000rpm?

 

No body has a dyno comparing different dynos?

Jay Kim

 

There was a for sale post in classifieds for a used one he said he made like 8 hp over his jdm itr
I cant find it thou

 

Damn, 27hp?!

I'd like to see a dyno plot on one, especailly on a high-comp B18C1.

Any links?

 

****, 27hp might not even be enough to turn the roller!

 

hmmm, i wonder why racers like erick and bisi uses these header if it loses power? dynoes of the header by erick's racing have shown increases over a ported jdm header. reasons why AN-R.com and erick's racing sell these header. Think about it ... if it doesn't work, we wouldn't be selling it and people wouldn't be buying it.

I was not implying that it did not work, or wasn't a good product, or even that it didn't substatially increase power output, as it more-than-likely does. I was commenting on the fact that flow in the lower rpm ranges, with primaries that large, will be very weak. But headers like that aren't made for peak performance in the low-rpm ranges, so a loss down-low is to be expected. Headers like this shine in the higher rpm's. They are purposely designed to maximize power @ higher rpm's, as that is where ours, and most other engines, produce the most power. This maximization of power up high is usually at the cost of losing some low-to-midrange power. That's really what my comment was saying. I should have thrown in an hp rating of "HOLY ****" from 5000rpm to redline to verify that I wasn't down-talking the product. My bad.

 

actually, from the dyno plot i've seen done by erick's racing, our header had no low rpm loss when compared with the jdm 4-1 header.

Here is my AN-R header in my car. JDM GSR engine running 12.5:1 CR. Ill be getting it tuned and dyno'd in about a month. Ill let you know how it performs. Im hoping for 210 to the wheels with a built head.

I'm skeptical. I agree there will be gains, but not at the *low* rpm of 5000. I know enough to say that for a 4-1 header, for mild mods, 1.625" primaries work well. Like someone said, "why would racers use this if the gains are so small?" They'd use it if it has good gains *in the rpm range of interest,* at about 8,000 - 10,000rpm. Why people foolishly put Real Race components on their car is pretty funny, because they are useless in 99% of "normal" driving.

as my post indicated, i'm not making any claims that the header produce gains in the lower rpm range (comparing this to the jdm header). what i said was that there was no hp lost. now, if you were to compare this header with a stock header i guarantee you that there will be hp gain in the lower rpm range vs the stock one.

 

Compare it to a USDM DC Sports 4-2-1 header & show me the dyno down low. Which do you think will look better? Not to say that the DC Sports piece is a good header, or anywhere near the quality of the header we're talking about in this thread, but I hope you get my point. You're taking a modded engine that's already aimed to what that header is meant to maximize, and improving on it. The damn thing probably didn't have any low-end to begin with. Sure, it may be a good indication that this header is better than an ITR, and that was probably the goal when manufacturing the header. It's a good accomplishment & apparently, a damn-good header. That's all well & good, but don't try to make it sound like this header doesn't follow the age-old compromise of taking away down low to add up top, especially with it being a 4-1. Well designed 4-1 headers do not give you the scavenging effect from the cylinders that similarly well-designed 4-2-1 headers do in the lower rpm. That is not debateable.

 

the motor that was shown in the dyno plot was a stock motor. no mods were done to that motor. now, i dont' have a dyno plot of a jdm 4-1 versus a stock header, and with that said .... you can go to http://www.importreview.com/reviews/JDMRvs4-2-1.html and see for yourself. though the jdm doesn't look as good as the 4-2-1 header ... the overall hp output outweights it. btw, when was teh last time you "race" your car and shifted at 5k rpm?

Snail, let them think it sucks... poor souls... you dont need to justify the header, it speaks for itself. God forbid a non-traditional header be made. I love mine.

-Nick-

 

how much longer are the specials for. i really want the the crx one, at the good price. and i almost have enough money

 

it is ending at the end of the month.

 

For the price Snail is offering this header for, how can you NOT get it??? It is all of what, $75 more expensive than a JDM 4-1 header?? Come on now... it should be blatently obvious that this header will give more top-end than the JDM 4-1.

Just wait for my dyno sheet... it will tell all.

-Nick-

Oh and it gives the exhaust a wicked tone... very very nice!!

 

Okay, just ordered off the site.

 

you will not be disapointed... I promise.

I am willing to go so far as to say I would even refund you your money if you aren't satisfied. I have no buisness relation with Snail EG either, he just makes one hell of a header.

-Nick-

 

Damn I want the one that twists to the side so I could keep my radiator.

Jay Kim

 

You dont' shift at 5000rpm when you're racing - that was one of my points that seems to have escaped you.

No mods? So you bolted headers, each with a 2.5"collector up to a stock exhaust & made your comparisons? Stock intake? When have you ever seen a racer, outside of class restrictions, keep these things stock? C'mon man, that wouldn't make a damn-bit of sense. The vast majority of people that buy one of these headers are NOT going to be running the stock exhaust or intake, plus these mods would no-doubt improve your overall power output, so it would be in your best interest to have these mods done @ the very least...

And for some unknown reason, you continue to preach to the choir. Can y'all not read? I've given you all the props in the world, yet you still dont' seem to understand, so I'm going to close it off with this; show me dyno plots of your header vs. an SMSP, or Hy-Tech header.

'Nuff said, you lose.

Now be sure to reply that your header is half the price of those, and makes more power per dollar spent... blah, blah, blah.

 

the dyno was done by erick's racing. and we were told the motor was a stock motor. don't believe me? call erick's racing up, they sell the same exact header. the purpose of the dyno was to compare the two headers, not to see how much the car produced hp.
you want to compare smsp or hytech against our header? those header to custom made to each specfic motor. our was designed for mass production.
btw, i don't understand how i'm disagreeing with you. i agree with you but you still think i'm not. btw, what header do you use?


[Modified by Snail EG, 6:08 PM 10/22/2002]

 

I believe you that it was a stock motor, I have no reason NOT to believe you. I would just think that it would be a better idea to do the comparison on a modded motor, but what do I know?

I have an Airmass header w/a custom collector on their now while I redo the collector on my JDM 4-1, my original weld-job was... well about the worst weld job you could imagine. I'm eventually going to make my own header to have a bit more flexibility & really be able to see what my engine likes. I just need to find a place to buy the head flanges.
