These are great numbers, I am growing increasingly concerned that I need to have my motor gone through---:evilb:

I hope to GPS mine in the near future! I'm expecting somewhere + - 90mph. procharged 454 Bravo 1.5 30P Bravo 4 blade.

'86 22 Pachanga

bone stock 350 Mag

23 Quicksilver Tempset, 4900 rpm

Light fuel, one person 62.2 gps

How is this prop on the hole shot? Are you using trim tabs to get up on plane? I have the same setup with a OEM cleaver, trim tabs(get me up fast) and I can get like 55ish but running out of revs too fast. I need to check the timing tosee if theres not enough advance.

Where do you run at in Nebraska?

The only waterway, the Missouri River:D Mighty Mo
The Longest river in the United States for you trivia buffs.

There are many times I can not open it up because to many boats in the area.

Bet thats a rush running with the current i've seen the river and it moves right along

Top Speeds
 

77 mph @ 5200 rpm. Lake like glass. 1/2 tank fuel.

man you guys get some speed out of your changa's! I'm hoping to GPS mine in the spring. need a better prop first.
setup is an edlebrock intake mani, comp cam and lifters its only the 5.7 though. I'm hoping for mid-low 60's. I'd love to be able to get my hands on an alpha SS, but its not in the budget right now:(

The stock 330 big blocks would only do 65, you are going to have a hard time getting there with a small block:eek:

I posted an Apha SS for sale ($1,500) here in town a few months ago. He ended up selling it local after a few weeks.

I did not know they offered a small block in 1991?

actually I've read that the 350's were only a few mph slower then the 454 in the P-22 so that's actually very encouraging! the 5.7L was rated at 270hp that year + the upgrades hopefully put me in the neighborhood of 290-300hp. the previous gen 454 was rated at 300hp and weighs more so...its not completely unrealistic, although I know better then to try and wish for any more then 65 with the SBC

guess its easy to speculate all of this from my computer chair :D now comes the torture of having to wait for 6 months to see if any of my theory is true :(

cincinnati, OH

There is plenty of boating time left I am going out for my last run this weekend:ernaehrung004:

They are dropping the river after the weekend.

I had a 87' 22 before I bought my 32' it had a 454 and clocked at 70 with a half tank of fuel. the only mod was a nosecone

Pachanga,

I used to have a 406ci SBC worked over pretty good in a 22' Stinger and was only in the 70's. I currently run a pair of fairly well built (but not dynoed) 454's with B&M 250 blowers (about 565hp a side) and still only in the 70's.

I would think you're going to need 650+ hp to see 90 and that's going to be tough if you want reliability out of a 454. I would recommend procharging maybe a 540? Unless of course you've already built the motor? Let us know what's in the motor and your test speeds! Good luck.

Wow! This sight got busy!

Well...I haven't seen the #'s I want yet. Finally bought a GPS. I have prop problems...and listening to some of the veterans I don't want to push it without external steering. Last year I buggered my 30 Bravo up just a tad. Had it redone over the winter. Turns out my prop was labbed before and now is stock. I lost all my bowlift and she chinewalks pretty bad when I push it. The bow stays completely planted in the water dead level! Before it would cruise along on the pad. The prop is also slipping quite a bit more. My carb is also loading a little...making it run too rich. Best speed I had the balls for and my wife let me do was 78mph on GPS.Because of the chinewalking,etc I couldn't watch the tach too close...had my wife watching the GPS. Think I was turnin somewhere around 5100. (funny part is everytime the conditions were right and I felt hooked up good I didn't have the GPS on and the ladies started screaming!) Kindda got in a race with a 27 Baja...started easin up on him and the women started screaming! Talked to him later and he GPS's at 80...so...who knows! I had a little bit left and hadn't trimmed all the way out.

Next year things will be different!(if we have any lakes in Ga to play on) :D I have my boat in the shop for a winter project. If all checks out with the hull and stringers I am going with external steering,trimtabs(guy says I should put the factory tabs back on)...what do you guys think? I think they are 9" X 18". Rebuilding the carb and coming down a little on the front jets...runnin 102's on the back! Fronts were around 78 I think.

I should definately be making more than 600 horses. 454 .30 over,fully balanced steel bottem end,forged pistons(supposed to be 8:1 but I think they are closer to 9. Pumps 155lbs-160 lbs. on compression test. Mallory Ignition,Crane ultra marine full roller set up with 1:7 rockers,Ferrea stainless steel valves,etc,etc.Blow through procharger set up with the 9lb pulley. Still running the stock exhaust but also plan on putting aluminum exhaust on this winter also to take some weigh off the arse end!

Pachanga project is officially underway!
 

Well, I delivered all the goodies to my boat guy today. CMI Sport tube headers,had the tabs, and a full hydraulic tilt helm IMCO duel ram steering system.

Got to talking with my guy. I bought a 29 Mirage +. He doesn't think it is enough prop. Brett A Bblades wanted me to try a 25 or a 27 1st. My guy says he is not aware that I have a pretty high X dimension from changing over from an alpha to a Bravo. He thinks I will need to stay with the 4 blade and have it labbed again. Damn I wish I hadn't had to refinish it....sure seemed to be the right prop before. He also offered me some info I didn't know! He had it up to 84 on GPS @ 5300RPM's and said there was mo motor left!

Hoping to have an awesome boating season thios summer....Come on and rain! Fill our Ga lakes back up! :D

Are any of you other pachanga owners doing any upgrades this winter????

1987 22 Pachanga
89 mph (gps no BS)

MSD ignition module, Bravo 1 out w/ Lab finish Mercury 26-pitch 4 blade propellor. 491hp on dyno.

This boat FLIES!!!

That was with 2/3 tank of gas, average amount of gear I guess, and me. The motor was built 4 years ago and for those that may be interested it cost $25K. But I bought the boat from the guy that had the motor built and it had less than 60 hours on it when I took possession. I acquired the boat in June 2008. I had a complete investigation of the motor and it is a tank. The all purpose prop 23p 3 blade stainless (gets my kids up on skis and tube easier) pushes the boat to 72mph (on gps) with the same set up as stated before (2/3 tank of gas, average amount of gear, and me). I absolutely LOVE this boat. If I can figure out how to post pics I will.

How many RPMS is that engine turning?

You have to pay $$ to post pictures.

With the 23p 3 blade it will get to about 5300 rpm, with the 26p 4 blade it gets to about 4700 rpm.

That's amazing.

Using a prop calculator with your 26inch prop with 10% slip ratio you would need to turn that engine 6,000 RPMs to achieve 89MPH. 10% is also excellent and a 4 blade will slow top end also.

Sorry don’t buy it, just my 2 cents.:party-smiley-004:

I am over 500HP with a 496 and a labbed 25 mirage plus 3 blade and only see 73 at 5,100 rpms.

I also find it difficult to believe. I have a 600+ HP procharged 454(.30 over) with a Bravo 1. Best seen so far was around 84 with a little left twisting a labbed Bravo 30 at around 5400 RPM's. Unfortunately it's gonna be next season before my supposed winter project is finished. The damn headders wouldn't clear the procharger so it's gonna get the 496 manifolds off my sunny when I do the Raylar kit.

Good points gentlemen. I also just did a calculator and came up with the same rpms...so either my tach is wrong or my gps...which one I couldn't guess. But GPS speeds are usually spot on right? I am going to have my mechanic look at the tach next Spring when he unwinterizes her. Thanks for the heads up.

But I do know that this boat is the fastest boat I have ever been in, and I have a bass boat that does 78 mph with a 225 Optimax spinning at 5800 rpm on GPS and my Pachanga certainly feels faster than that. So, I guess my tach could be off.

Just did customers 86 with whipple stock 5.7 conned alpha 9 lbs boost 27 pitch 5200 75 mph gps in small lake no room today tested it
