I wasn't asking, I was suggesting. This isn't my deal.

Great news. Greg's Dad (Gary) called me today and he found some of Greg's old paperwork for the Spectra. Hopefully, this will put some of the missing links together for me.
I think I got a good idea on the Compression Ratio and Effective Compression Ratio. Thanks goes out to WESTERNAERO for proof reading and helping me grunch some of the numbers. :biggrin:
With .043 Gasket
ECR = ((Boost / 14.7) + 1) * compression ratio
((6.5 / 14.7) + 1) * 8.26 = 11.91
I found some of Danny's old posts on www.riverracer.net. Shaun the owner of the site had saved a lot of the old Hotboat.com posts and threads prior to the magazines meltdown. The following posts lead me to Greg Shoemaker. I am working with Greg to get the Cam Card and the Dyno Sheet. It's a long shot but Greg did put a call into Dan Douglas and he said he would look for them.
...Well, looks like my boat sold less power so I have a motor that needs a new home. Looking to get rid of it. Motor has 1 hour of dyno time since it was torn completely down, checked out, and rebuilt. Motor maybe has 30-40 hours on it TOTAL. It has all of the best parts in it.
...World Industries block
...Dart Pro 1 polished CNC Heads
...The Blower Shop 10-71 Blower
...MSD 6M Ignition
...Super Chiller
...Two Gary Williams Dominators
...Billet Crank
...ARP fasteners
...Etc.
...Motor put out 989h.p. on 6.5lbs of boost on pump gas. The motor is way over built for where it was running. A duplicate motor on Race Gas put out well over 1200h.p. and there was still room to go. There are no issues with this motor and it starts, idles, runs, perfectly. I can produce dyno sheets and will pay for an independent mechanic to go through the motor and sign off on it. Once that is done, that is where the warranty stops. I am 100% confident in this motor or I would not be selling it. As with anything high performance, there is NO WARRANTY what so ever once your mechanic gives it the green light.
...I can also help whoever buys this motor install it in their boat. You get the motor complete marine (less headers & motor mounts). Everything else is there and is ready to drop it in the boat. This would be a great re-power or something for a new boat awaiting production.
...Just FYI, I am looking to get somewhere around $18-20K for this motor. Call up Pfaff, GT, or Teague. For something similar, you are looking between $40-50K
...Initial is about 8 or 8.25:1. When I say pump gas, I mean 91 octane. That is what we ran it on the dyno at and no problems. Knock sensor didn't detect anything. Just to be on the safe side, I always splashed between 5-10 gallons of av gas into the tank prior to running it. Cheap insurance on the motor. They say that fuel looses between 1-2 octane points per month. Last thing you need is to have the fuel sit in the tanks (either in the boat or gas station) and pump bad gas through a high performance motor. It would live on 89, but I DO NOT suggest running it on 89 (much less running it hard)!
...Nope. You didn't miss it, I forgot to add it. It is a 572cid and it was built by Dan Douglas from GS Marine. He owed me a favor and did this motor for me. We worked with a bunch of different builders to get the ideal combination. Tom Papp was in on it, Dougans Machining, PFM, Westech, etc. I ordered the parts and had them delivered to me. We then got together and I watched as it was assembled. Dan Douglas did all of the assembly and then it was dialed in by Steve Brule over at Westech.
...By the end of the day, I was very happy where the motor ended up. It puts out 946@5600 and the lowest we pulled was 4500rpm and at 4500rpm the motor was making 954ft/lbs of torque. (And I was wondering why I keep going through drives). Steve Brule from Westech said that I could get an additional 100-200 H.P. if I wanted to run race gas, but I opted to stop there. I am only running 6.5lbs of boost and the motor is fat and happy.
Greg Shoemaker called me yesterday saying Dan Douglas found the Cam Card and the Dyno Sheet. Dan's on vacation right now but he should be back this week so hopefully I have that information by next week.
Also, Greg's Dad pulled through for me and found some of Greg's old paperwork. This is some of the work Hi Tech Marine did on the Spectra.

Update?????
No real updates at this point. Greg Shoemaker told me Dan is still on vacation so no cam card or dyno sheet. Lew Larson told me that the machine shop is waiting on rod bushings.
Dan Douglas faxed me over the first Dyno Sheet from 2002 with 5 PSI. He didn't find the one they did with 6.5 PSI.

Lew got the rotating assembly back from the machine shop. The engine is now an internally balanced engine instead of internally balanced on the front an externally balanced on the back of the engine.

We took the heads to JMS Racing to get pressure checked and cleaned up.

Looks mean!!
Most of the engine components are installed. The transmission is in and Scott is working on the wiring. Hopefully, I will get her back home this week and finish up a couple small things like headers and plumbing. Then back to Lew's to light her up.

Hopefully, water test next week.

We water tested the Spectra at Lake Elsinore.

However, we have a problem (you can hear it in the video) as pressure builds the TCI Pump Drive is being pushed and disengaged from the trans pump. In the following picture you can see the Pump Drive was pushed over a 1/4 towards the engine.

I called TCI Auto and one tech told me that the TCI Pump Drive wouldn't work with and 3/8 mid plate and another told me it would work (they really couldn't give me a explanation of why or why not). So I starter thinking what would cause the adjustable slip collar to not hold the drive in place and I am wondering if it's because of the tapered spline. The 3/8 mid plate is causing the slip collar to be placed on the downward slope side of the spline. Therefore, only a portion of the slip collar is actually locking down on the pump drive. Give the drive 250 lbs of pressure and it pushes the slip collar down the slope. So to make it work I would think we would have to make a spacer for the slip collar so it would place it off the spline at a level part of the Pump Drive. Also, I started thinking about what else could go wrong using the TCI Pump Drive and it appears that there would only be about .625" of spline in the flange when using a 3/8" mid plate. So to over come that we would need to used a 3/8 plate spacer behind the flange that is bolted to the flexplate. This would allow us to use the no motor plate slot (b) on the TCI Pump Drive with the spiral lock. Then add adjustable slip collar with a spacer for added safety. This would put the spline in the geared part of the flange about an inch. To be honest though I hate doing all these workarounds.
I was reading on the boating boards and a lot of the guys have had good luck with the Heavy Duty Hughes Performance Direct Drive Assembly. I talked with a tech today at Hughes Performance and he said that the build time is about 2 days since they custom build each one. They build them to the mid plate size (3/8) and it's one piece so no workarounds. It's $269 and I am pretty much ready to order one of these deals and be done with it. It's the three prong type set-up on the left.

So it was the drive and not the pump. I would never have thought that the collar would slip like that. Are you sure you tightened it?
