Westech Dyno Session 7/23/18

[Chris Lapoint]

Well tomorrow is dyno day with Steve Brulé @ Westech.
This motor was built a few years ago by a reputable motor builder but was never dyno’d (family friend).

Any guesses on HP numbers?!
I am thinking in the 700~ Range.

Forged 468” BBC Mark IV
12.5:1 (110 Oct)
Steel Crank, Good Rods & JE Pistons
Edelbrock Performer RPM 454-R 315cc Heads
Good valves, springs and match ported.
Engle Racing Cam - Solid Roller .690" Lift
(2) 750cfm Race Demon Carbs

Why to the dyno now?

 

[Chris Lapoint]

Why to the dyno now?

Because good can always be better.

 

[wzuber]

nice looking Sanger Chris. A little more info. would be helpful to determine a reasonable guess. At 1.53 hp/cu. in. I am going to say your prediction is pretty accurate at 7500 rpm-ish. What rpm do you expect it to run in? How much, what kind of work has been done to the intake tract? Good luck on the dyno day, always exciting and anxious at the same time. Hopefully when you get'r all dialed in and a re-installed in the boat you will post a video of launching, making passes etc. Where do you typically run your boat?

 

[coolchange]

Ok, under 700.
Just because I don't like demons. LOL

don't like demons or B.G. more specifically? I understand he pissed a lot of people off with his "customer svc" or lack there of.

 

[stoker2001]

those Eddy OTB RPMs will hold it back?7500 RPMs with those heads?good luck

 

[wsuwrhr]

Good luck. If I was still in Riverside I would stop in.

What happened to the rag on the chain against that bad ass fabbed valve cover?

[rivermobster]

No guess here...

But I dig that boat!!!

My experience with demons has been on hot streak stuff and I just don't like themlol. Minimum experience with them.
I would think you need dominators and biggerheads to be hard in the 7s. Hope you get your numbers though.

 

[wsuwrhr]

Im sayin 650-675 on the outside.

Thinkin the carbs will be the limiter as well, then the heads. What size valves are in it? Cam lift/duration/rocker ratio?

 

[Chris Lapoint]

It’s just about that time, typically the boat runs a 7200 chip in it.

I do love me some big blocks driving a dyno on the pipe.

[SBMech]

I'm going with 731. Looks like some good stuff in it.

 

[brgrcru]

707 hp my guess

 

[NicPaus]

692

 

[Backlash]

670-ish.

 

[thmterry]

648, it is really hot out.

 

[River Lynchmob]

675.

 

[wsuwrhr]

Where we at? Still making pulls on that ol girl?

 

[4Waters]

I'm going to say 700, but my gut is saying 750

 

[Jonas Grumby]

695 with the bad air today.

 

[Chris Lapoint]

About 7 pulls in and we reached a safe 670hp @ 7200rpm.
For the components on this motor, I am very happy!

[Chris Lapoint]

Let’s see if this link works for the video of a dyno pull.

haha yeah, not the most economical boat I've owned.
It also had 103lbs of oil pressure @ 7,200rpm *YIKES*

Yea, you prolly need to get a look at that relief spring before you put that oil girl back in.

Big Block Mopars have an external oil pump.

Wow. That probably cost you 15 horsepower. LOL

[Backlash]

Same movie, just an earlier scene. It's the scene where Old Man Pappas first meets Johhny Utah at the training pool. C'mon keep up Brother!!

Couldn't find it.

Apparently you were distracted during the first few minutes! Too busy cracking open that cold beer and leaning the recliner back to notice!

 

[RACER J]

Well.. slap that puppy back in there and take it for a spin at the mendota slough. I'll be there Thursday - Sunday morning.

Nice! I am just going to run it to Lake Kaweah early Saturday or Sunday morning, I've got to put the motor back in tonight and then button up the wiring and cleaning this week.

I was up there Friday afternoon, its already a mud hole, can't believe how much it's gone down.

Good to know, we went a couple of weeks ago in the other boat and it was still ok.
maybe I'll just go to Millerton Lake, its only 25-30min further to Meadows on the (North Side)
