Are the block and the head true and are you always blowing the same gasket?

Chris

I've had two PC's.

The first I had many "gremlins" as you put it. But I was trying to get more from the blower than what it could give me.
Not engine problems. Just wasn't getting the power I wanted.

I now have a stage 4 and no problems...knock on wood.

I've always used the Fel-pro head gasket and it's carb'd.

Hey Dave how's it going? Is that a dual carb setup you are running? 504 intercooler?

Tom,

No. I was using single Nickerson 800 holley. I am using the 504 intercooler however.

I was running around 8-9# in the manifold. Around 10-12 in the box.

This weekend, weather permitting, will be the last for me and my Formula.
I sold it last weekend.

This couple saw the boat, commented how they liked it, I told them it was for sale.
They said "oh ya"
I lifted the engine hatch and they said, "HOLY $$$HIT!!!!!!"

Anyway, I took them for a ride, gave them the option for an HP500 or as is.
At the end of the day, they gave me a deposit at the dock! That was Sat. The guy calls me last night, says he wants to stop by and give me the balance. I haven't even started on the motor yet!

They said 900hp was a little too much, they chose the 500. So, this weekend is the last hurrah. I'll start on it Mon.

Two happiest days in a boater's life... I'm sure you will find something else to put that engine into. What are the dimensions of a Stage 4 compressor? Is the discharge 3.5" diameter?

Tom,

If I remember correctly, it's the 5.5" inlet and 4" outlet. The housing is 12".
I do have a dual box, still in it's wrapping sitting in the garage.

Believe it or not, I'm not happy to be rid of it, I am, however, looking very much forward to buying something newer, bigger and arguebly, better.

Life can't be better for me right now.
Sold my old boat and got the $ I was asking.
New baby girl on the way, due in Sept.
New boat by next season.

I'm sure that I'll be staying with a single carb. I plan on building my own carb box lid to accept the 4" inlet next time, however.

DAVE

Dave - Would you be interested in trying my improved intercooler configuration? You're modifying the carb box anyway. Send me an email to discuss.

Tom

Dave and Tom,
my M3 has a 3.5 in and a 4 out(?)
Dave, regarding your slippage from the other post,
what size was the driven pulley you were using. I have a 4.5" 12 rib that is suppose to give 5 lbs on a 502. I'm thinking that I'll need a 4.0" to achieve that on my 540. To make things worse I'm probably going to need to produce 7 lbs at our 4500 ft elevation in order to get to 135 kPa which would be the equivalent to 5 lbs of boost at sea level. This may require a 3.75" pulley and be about the limit for the M3. Was your pulley that small?
What size pulley was slipping on you?
Congrats on the new one!:p
Thanks
Dave G.

Congrats on your sale. Not often things happen and fall together for a person this well. Looks like there may be a "BT" coming over the horizion sooner than someone thought. Glad Mama is doing well and I know you guy's are thrilled. Keep me posted on the birth and I'll be looking for my Cigar (Never seen a Pink Cigar).
I would like to thank you again for all the help and advice that you gave me in the installation - setup of my ProCharger M3SC system. You guy's better pay attention to this fellow, he knows his crap about the ProCharger carbed systems. He guided me through to what has proven to be an outstanding setup. This carbed M3SC w/ a 504 intercooler starts and behaves as well as any fuel injected ProChager boat I have ever been around.
Now if I can just hook up all the torque and HP I'll be right. Hydromotives don't get it (to much lift and slip) and I'm waiting on a 28P Bravo I to arrive tomorrow. I don't know where that lack of bottom end power is at that they talk about while trying to plane, they must have it all because this system makes awsome power throughtout the RPM range.
Had to say it Dave!!! You deserve alittle respect for the help and knowledge that you provide to this board.

Nordic,

I was spinning a 2.65 driven with a 7.65 crank and a 3.05 trans. That equals 48426 impeller rpm @ 5500 motor r's.
Problem was, never made it there due to the slip.

So what I did was; send it back to PC and have them put a 3.36 gear in it
Use a Whipple crank pulley = 8.75
Used a 3.05 driven on the PC

That comes out to 53000 impeller rpm which is where I wanted to be.

Redline on the impeller is 60000, anything past 55000 is not doing anthing but heating up the air known as "stone walling"
Plus you risk harmonic destruction of the impeller above 60k.


Valley

I was wondering how you've been. I thank you for the kind words and good wishes.
I of course return the good wishes for the new grandson.
I wish you all the luck with the new PC.

When you want to step up to around 8-900hp send me the motor and I'll set it up for ya.
:D :D
When my baby girl is born, pink cigars for everyone:cool:

The respect has to be earned. Like I've said a million times on this board, YOU HAVE TO MATCH YOUR PARTS. You were willing to listen and take my advice and match them. I can't tell you how happy I am that you are happy with your system.

any time I can help
DAVE
