LOL, cf my comments were a direct feed off your kindergarten remark. If you notice, I later admitted my level might be jr high, and I hoped you were at least at my level. Really wasn't trying to start a pissing match here, sorry if it appeared that way.

So, how bout we go back to my real interest:

The blown BBC 18...

Thanks :)

Scott B 08-15-2012 03:13 PM

Tyler has a 22.. He is dialing it in still, it runs well. And I LOVE the no windshield look..

FWIW, my buddy Jim had (just sold) a procharged 454 22 classic running 94ish all day long. Nothing fancy, stock 454 with a blower and a shorty, no internal mods.

Keith's (Silverback) 25 had a pretty trick engine AIR, and not a ton more weight. It also was a pad hull as DW mentioned, and the pad was different from the factory than any other I have seen before or since.

I haven't criticized either of you but you 2 seem to want to say chit like that. I said Parnell is one of my closest friends and I guess in your little guy world you think that means I worship him. I don't give a fuk about the boats anymore and if you want to make is personal let me know. you don't know me guy.

and i've seen Parnells dyno sheets and his motor made well over 700hp. funny now the 25's motor is 1000hp but in the start of the thread is says 800??

with the proper hp that boat may reach 110 mph,,but not with a gm block that wont support the kind of hp needed for the boat to reach that speed for any period of time let alone trying to get to that speed...now i know the zx gets real squirly after 85 ish mph and i talked to the hedge last night and he also mentioned that you really have to know what your doing in that little boat over 90,,one little ripple and it could get catastrophic.

Scott B 08-15-2012 03:43 PM

Hey, don't be dragging my way into this conversation Fixx...

Biggus 08-15-2012 03:43 PM

I believe the 25ZX is a non-step hull with a small pad. I had one left at my dock for well over a year, (502Mag MPI) got to know it well.

We also set up a neighbors 25 Baja (very similar hull, small pad) with a M1SC Pro Charged 502, fitted with an R-Tech Supercooler (low restriction highly efficient intercooler) set up on Nickerson's dyno. Made just under 800hp. It was a struggle to hit 90. 110 mph. is just not believable to me.

Fun bench racing though!:daz:

I've been watching this thread with interest...

To set the record straight, Tyler and Logan are sons of a great guy named Gregg. Great crew and their 22 does run.

I did some prop testing/trading and set-up talk with the first owner of the 25Z. Based on what he was doing at the time, I have no doubt that it was running over 100.

I've run several times next to Parn in both of his boats. The GT is apples and oranges to a Z-boat. The GT is more like a Classic, and that one is built like a, well you know...

Edit: And to Biggus, I've spent my share of time beating up on benchracers on the Donzi sites. Most people said what I am doing with my Classic couldn't be done either. Not without a charger, but it does. Seeing is believing, and these boats can be made to do some pretty incredible things, including a 25Z at 100+. Agree with you on the Baja, as HP can only do so much with that hull.

Donziweasel 08-15-2012 04:01 PM

Not trying to start anything either, but you are the one who came on here claiming a boat you know nothing about can't crack 100, called out Scott B and claimed anything Parnell says is true.

First, Parnell is a great guy and a freind. He said at AOTH 2 years ago his Gt was in the 600 hp range. He also said his biggest obstacle to speed was the GT-21 hull and drive. The drive is simply too low to get big speed. The GT-21 was more of a gentleman's cruiser than a flat performance boat. It was never meant to go fast. BTW, there was a twin engine GT-21 made. Pretty cool if you ever see one.

Now to Keith's boat. If you had read the thead posted at the beginning of this thread on d.net about the build, it would have answered all your questions. Since it is 100+ pages long, I will summarize but not say what was done to the boat.

Kieth showed up with a pad bottom 25 ZX. Much like Scott said, no one had seen one before. There were a couple of guys putting big power into ZX's at the time, mainly Bill and Brian. Kieth had no experience, but did have time and money. He worked on oil platforms off the Louisiana coast. he would work a few weeks and then have a few weeks off, or something like that. Anyway, the 25 was pretty much stock as I remember when it started. He would ask advice, it would be given, he would try it and give us the results. The speeds went up.

Kieth tried ALOT of different things and setups. He would always tell us the results, and not all were good. About the middle of the thread, he would ask advice, it would be given by guys with decades of experience, and he would blow them off or tell them they did not know what they were talking about. IMO, he became too big for his britches and kinda a concieted know it all. Arguements ensued, he would be told he was an idiot for some of the sttuff he was trying as well as congratulated on some of his successes. Yes, I gave some advice and slapped him around some as well.

He made some big mistakes over the build and even got out of control in the high 90's. Through persaverence, trial and error, stubborness, will power, and a hell of a lot of help, he did get well over 100 mph. From what I remember, it actually handled pretty well and the finished product was pretty solid. You have to remember, the ZX was not the ZR and was more of a performance cruiser, not a race or true performance boat. I remembered he tried all kinds of things, extension boxes, drives, X dimension, and a ton of other stuff.

His attitude cost him though. He burned alot of bridges and lost alot of friends on d.net. He wasn't run off of the boards, just most wouldn't respond or deal with him anymore. When the BP spill happened, he said he was out of work and had to sell the boat. A couple of months later, he said he was going to keep it. Then he dissapeared. The Ebay ad said the boat is in Louisiana, where he is from, so it might be him selling it.

All in all, get a six pack, clear a couple of hours, and read the thread. It has it all, love, action, drama, fights, makeups, etc.... Most importantly, it has some really good advice on how to make a heavy, stepped cruiser go really fast. It is a good read with some damn good info.

I will say, even though I never really liked Kieth, the boat does go well over 100 and had alot of R&D done on it. Due to the ad description, I would say Kieth sold it and the new owner is selling it. Kieth was proud of his end product and he did alot to it. If it was him selling it, I would thing it would have had a 3 page description on it, much like the 100 page thread. More than likely, the new owner knows very little about it, like saying it has a 454 when I know it has a Mark Boos 502 or 540.

Heck, he was only asking 20,000.00. The engine, custom drive, exhaust, and other parts on it are worth more than that.

In the end, despite a bad description, the boat hauls the mail in well excess of 100 mph and is worth 20,000.00 easily.

Mike, he was well over 100.


I believe the 25ZX is a non-step hull with a small pad. I had one left at my dock for well over a year, (502Mag MPI) got to know it well.
Too be honest, I can't remember whether is was a stepped hull or not. I know Bill's and Brian's are, so I just assumed his was as well. I am sure it is in that thread somewhere.


Edit: And to Biggus, I've spent my share of time beating up on benchracers on the Donzi sites. Most people said what I am doing with my Classic couldn't be done either.

Todd, the Flowerpot is the fastest NA 22 I have ever seen. Your boat rocks.

Guys, Kieth spent BIG money on that ZX. HUGE money. Throw enough cash at a Bayliner and it will rip.

Funny thing is, when the thread first started, I remember Kieth was only looking for 80.

tnc110 08-15-2012 08:35 PM

The zx25 is not stepped. I originally posted this thread because I too have a pad bottom zx25. The reason for the post was to find out how safe this boat is at 100+. I want to go fast...but don't want to be sitting on the edge of the seat the whole time....

Sorry ya'll if I offended anyone!! Bad day yesterday!!

A couple of comments if I may

RT I told CJ that it was tyler logans boat cause he thinks it is and takes it out when his dad is gone:thankyouthankyou:

Scott No way you got past middle school :evilb:
Anytime you want a ride

DW Its north of 700 and bumping 90mph without a correct gear ratio and the right prop so I do consider it more than a gentlemens cruiser of which I'm not anyways. Its 622 ci with a tunnel ram and polished and ported heads Pretty easy to get 710hp and run like it does so docily. I did get a shorty on there which perked it up Its light years ahead of where it was when I started and it has plenty left to find I assure you
Obviously a well dialed in 22 like tripper's is going to run it down eveytime with the same power but it does run out well in snotty conditions

Clearly Mighty Mouse is the sickest classic ever and I might add one of the three or four sickest boats I've ever heard about.

Lastly I dont know chit about newer Donzi's other than I saw hedge and texan going by me so fast my neck hurt for a day on that same hot humid day. Wasnt there always some questions about silverghost and his claims

Yes, I had heard about a certain stainless chain through the rims option added to the trailer when Dad leaves town. Boys will be boys...

Thanks for checking in here Parn. To the rest of you, come join us, we have a ball making these things do stuff people say they can't do, and there is always room for a few more!

Parnell, what's up my man? Been a while. Last time we really talked about the GT was at AOTH 2 years ago. I was blown away by it as you know. I remember you saying the drive was too low and the engine had given you some minor headaches, but nothing major. I never meant to imply your particular GT-21 was a "gentleman's cruiser", just that the original design by Donzi was. Yours is more of an insane beast than a gentleman's cruiser. Sounds like the shorty was the way to go. Sorry I missed you guys in Chattanooga this year, just wasn't in the cards. I will be at either AOTH, or more likely, Chatanooga next summer and look foward to catching up. :)

Nauti Kitty 08-16-2012 05:27 PM

DW Hope alls well in your world. No offense at the gentlemens cruiser quote I know exactly what it was. I ended up getting my whole engine rebuilt this winter and she perked up a bit. its all good She does run a bit more beastly now The shorty was key as I suspected.
I told Todd this summer its running so nice I just havent had the time or energy to make these next steps I know will speed her up even more.
Chat was great and I plan on getting back to aoth and chat next summer great runs and great times with cool people.
Say hi to Boo Boo and hope the twins are getting old enough to run the boat
