Default Z1 vs Motordyne

Which plenum spacer is better for an '03? Performance-wise... and sound-wise... does anyone have any experience with both? Dyno comparisons/averages?

i would go with motordyne just because its been around so long and ive seen the amount of work Tony puts into designing products.

After saying that im sure that z1's is a great product.

um, if they are the same size spacer the results should be the same. it depends on who you want to buy from and how much you want to spend is what it boils down to, personal choice is a beautiful thing.

Flip a coin...
Performance differences between even a 1/2" and a 5/16" are minimal

Motordyne by a long shot. He was the first to develope it and all the other companys copied his design.

Also the quality on his products and kits he sends out is 1st to none. It is the best.

Some spacers do not come with the middle supports like Motordynes do and the plenums crack without them sadly. This is where MD did his research and sends those to prevent that. But the copycats didn't care.

I purchased the Z1 plenum recently and its a great product. Bryan is a great guy and ships very quick.

To answer your question its pretty much your personal preference.

Motordyne all the way, Tony spends more time making sure things are perfect after the sale than most do in R&D and the initial sale in the first place.

Tony is a very knowledgeable guy and one of the best customer service of any industry I’ve ever experienced… he has a sound technical background and made some stellar decisions in the way he has produced and provided his products.

However, he was not the first to introduce the plenum spacer… a composite spacer that was absurdly overprice was first introduced out of Japan. Esprit was the first.

The early days of VQDE provided primarily modified plenum as a cost effective solution to the choked front cylinders (e.g. Crawford, then Kinetix) – Tony saw a need and filled the gap for fellow enthusiasts with his variation, a cost effective alternative to reconstructing the entire plenum.

Motordyne’s products have excelled because they are tried and true and priced within reason – independently dyno tested and endorsed by thousands of testimonials from many enthusiast (me included).

Other manufacturers saw the success that Motordyne achieved and wanted their piece of the mod money pie – therefore today we have many variations of the same principle – originally developed in Japan with overpriced US dollars in tow.

Having that been said – Adam from Z-1 is a great contributor to the forums and (from what I can tell and have researched) provides quality, tested products.

Motordyne is dedicated to specific performance areas and conducts detailed testing and outside-the-box approach to sometimes common and less than complicated areas of tweaking. Tony’s ability to analyze and evaluate an area for refinement is very unique and his solutions are brilliant.

Okay – that’s my view, but what it all comes down to is preference (as someone else stated) – Google was successful because the “in the know” liked their approach… but they didn’t provide anything that wasn’t already done – they just did it in a way that was appealing to the ones that mattered.

I’m a MDE fan btw.

^ Well put but it could also be said that Motordyne was the first to (a) document and disclose the gains with independent testing and (b) provide a reasonably priced product for the US market.

Those that appreciate his initiative and effort can choose to reward him with their business.

it's not Z1Auto is it?

and Motordyne all the way. I cannot stress that after the sale support is the most important thing and I honestly don't think a single vendor on this site can touch his attitude or support. Especially considering how inexpensive his products are.

I think he meant Bryan from Z1 Motorsports not Z1 Auto LOL. Everyone always gets those 2 vendors mixed up
