Dickmeyer Automotive Engineering Race Header B3/B6

[Festevil3]

What I believe bhazard was saying is that the header itself is NOT the power producer, but it IS 1 of several, well thought out modifications that, when combined, has shown over 110% increase in power, & this is just scratching the surface. There is more to come! It is frustrating, however, developing, producing & bringing to you guys performance products, which are needed to further your cause & than hear you complain over $300. But it has to start somewhere. If you can see it from my point of view, all the time, engineering & developing, testing & building & then ALL the equipment that is required to make these products available, NOT ONLY to YOU but to ALL of my customers, building that header cost me nearly a quarter of a million dollars. So in retro spec, $300 is not that much. Please don't think that I am being pissy cause I'm not, I don't just snap my fingers & this stuff appears. I am just like you, I need a pay check on Friday as well.

Great work! keep it up, don't let the "haters" get to you.

And i WILL be placing my order sooner than later.

Re: Dickmeyer Automotive Engineering Race Header B3/B6

Not to mention the equation the header is just part of...

[FestYboy]

think of the % of gain vs. dollar spent, not just # of ponies. given that, you have a 8/63=12.7% gain in power/$300=0.04233% per $ spent

now i'll take the 350Z as another example

it has 306hp to start, now lets add a cat back exhaust to it and it gains 6hp (as shown HERE), that's a 2% increase (rounded up) with a cost of $835.

running the math again, you get 0.0024% gain per $ spent which is horrible

Matt's header is the better investment in compairison.

Harley Davidson mike. Work hard play hard! Ball so hard!

Edit: 300 for that hp gain is steep.

What do you expect? Just throw some tubes on and bam +30hp?

$300 for the complete header ready to install.

$300 is a very good price for such a high quality unit.... if i still had a b3 in the festiva, i would have already placed an order lol.....

[FestYboy]

the festiva GT-A had the DOHC B3 (Japan only) and made ~88hp. Bert the 73hp B3 that you refer to is installed in eastern market 323s (BF/G only) and Laser, they mistakenly pulled the info from the Mazda B series engine article without verifying which cars it was installed in. the higher HP engine was destined for the larger cars (323 and Laser) where the Aspire and Avella kept the 63hp version. they also state the the 72hp engine is a 16v sohc. i've seen one of these heads and they are WIERD and i can't say that they'd swap over without all the fixin's to go with them.

that and the FSM also states 63hp...

[Festevil3]

^DOHC b3 hmmmmmm that would be awesome

[Bert]

Bert, all North American EFI B3s are 63 hp, and the Aspire exhaust manifold is horrible for scavenging, so they were stealing from Peter to pay Paul by running the roller rockers...

I don't doubt that, but I'd like to see some numbers. And your valued and expert opinion is the first of these. Next question: What did Mazda do in other markets to come up with 73 hp out of a B3? If Saipa/Kia/Mazda or someone else actually makes twin cam heads, that we could affordably get hold of, that would be a real boost.

Gidday mattdickmeyer! This business of yours with seeking to improve B3s is quite intriguing. The roller rocker arm cylinder heads of Aspires are supposed to be better performing. Wikapedia: " Mazda B-series engines" says carbed B3s were rated at 58 hp, EFIs 63 and that later B3 models were good for 70+ hp. Is it possible that Aspire B3s are that much more powerful and have you ever looked inside one? The manifolds and injectors are larger and the exhaust manifold is tube steel instead of a casting.
My very limited understanding of headers is that 'tuned' versions have functionally-equal length pipes going into a collector and that taking into account bends and/or curves in order to do that is a real art.
I'm following these posts with great interest.

To be honest, I tested that over 3 years ago & didn't keep the file. As I recall header was worth around 8 HP on a stock Festiva & around 14.5 HP with head work. I will be doing some testing on some parts that I am developing at the present & bought a stock '91 Festiva to test with. So I will be able to start from scratch with base line numbers all the way to highly modified.

Good enough. IMO, those are pretty substantial gains for a 60hp start. I'm really curious of the potential gains on a B6, since the stock B6 manifold is a little better design than the B3. I suspect it would be similar, all thing taken into account.
