I decided to make some changes to the 511 that should let it breathe better up in the RPM range that it likes to live. I have been told by many knowledgeable people that I was choking the top end with my cam and carb selection, so I'm doing them now, and I'm also going to port my manifold to exactly match the heads I have.

First the carb. I called Patrick James at Pro Systems. I was told he is the guy to buy carbs from, since He would match it to your engine/vehicle/use. So I went to his website, pro-system.com, to check it out. Well, I guess He knows what He's talking about, after all, He builds carbs for some VERY well known names, like Kenny Koretsky, Billy Glidden, Jeg Coughlin, and similar. He gets all my info, and says He'll build me a big 'ol Dominator, custom tuned to my app, with all the goodies, just bolt it on and go. Best thing is, it's only $100 more than a box-stock 1150 from Summit. Here's his reply:

"Our XC Dominator is the best way to go for your
combination. It's priced at $890.00 It has a true
race fuel curve, our Red CNC Billet boosters (to
amplify signal and aid in launch, throttle response
and shift recovery) they have our adjustable air bleed
configuration, non-stick gaskets, off road floats,
hi-flow needle and seats, a complete wet-flow
portfolio, a real sharp piece. You can spray it up to
a 350 shot if the need arises.

So don't worry about the carb, I'll have my end done.

It'll flow in the 1060 to 1100 REAL cfm range (I'll
know more when I'm flowing it for the application).

We don't have part numbers and each one is built just
foryour program. So I just need about 5-7 days to
get one built."

As for the manifold, it is currently gasket matched, but it still has much smaller ports than the heads, so I'm gonna open them up to match. The ports in the head are so big that the porting in the manifold is going to break through into the pushrod holes, so I'll have to sleeve them. I'm also going to do the machine work to open the carb flange up to Dominator size at the same time.

I also just received my new cam. It's a Comp Cams custom ground roller that is just a little bigger, and on a tighter LSA than my original cam:

304/310 adv
266/272 .050
.700/.711 lift
108 LSA
104 CL

It should REALLY make the HP up top.

Sooooo, that is what I'll be doing for the next couple of months.

By the way, I've got a spare, low miles, 850 Mighty Demon I'm not going to be using anymore if anyone is interested.

-Scouder

 

Cool, hey Brian send me a pm or email on a price, been wanting a 850 for a little cleveland motor.

 

Hey Scouder,

Now that is what I like to read when it comes to customer service. Pro Systems seems like HIGH quality... I am interested to see what new hp numbers your monster pulls now???

Keep us informed...I'm especially interested in the new carb setup...

OBTW...how did your Demon perform? Easy of tuning, quality, etc. (just curious)

Damn Scoot, sounds like your coming up on Jays build....LOL.. your Truck is going to be one BAD SOB thats for sure!! Hell it allready is!!

And we know what Jays build did to the others on Drag week!!! I also like the isea it'll take a 350hp shot of jolly juice...Very Nice...and ya cant beat that price for a custom made carb just for your application!!

Out of *****s and giggle's...what kind of Hp and Tq are you looking to get now? I take it that you werent happy with 750hp? LOL...Damn a man after my own heart..when 750hp aint enough!! I love it!

Good Luck and keep us posted !! You Mainiac!!

So far it hasn't been getting anywhere close to the 700 range. The only way I'll get that is to pull out all the stops. With these changes, I should be real close. Jay's engine did 706 on the dyno, and when I'm done the only real difference will be that he used a longer rod combo, and his cam is ground on a 110cl, where mine is on a 108.

-Scouder

 

Damn Brian..thats still alot of HP.....how big of shot of Jolly juice do you have the truck set up for now? I take it then your shooting for 1000hp overall...Man Bro..thats Smokin!!

Russ

 

Sounds like you're pulling out all the stops. Can't wait to see how it performs!

 

Sounds like a good match

Somehow I missed what specific intake you are running though...I just saw that you were going to open up the ports...?

 

I don't have any complaints about the Demon. In fact, if I hadn't found Pro Systems I would have considered purchasing a King Demon.

-Brian

 

Right now I have the 160hp jets in it, but until I get the engine doing what I want, I won't mess with the spray. Once everything is dialed in, I'll set up the fuel pressure safety switch, full throttle switch, and 1st gear lockout switch and start tuning the giggle gas. Ultimately it would be cool to have 1000 sea-level HP.

-Scouder

 

Hey Pro,

Good to hear from you again. How's that monster of yours doing? BTW I have a copy of the famous Blazer dragging video. Very classy!

I have the FE Victor, by the way.

-Scouder

 

Doing good. I had to upgrade my axles to the larger chromoly 35 spline stuff and CTM's $$$. My big project this summer has been building my shop, then I can get crazy. I figured you had to have the victor since its the best choice, but thought I'd check. It sure is nice to see a motor like yours...some folks need to be reminded that fear starts with FE
