Vegas Mike....it's time ! ***Dyno numbers are in + Pics***

[firefighter3931]

Hey Mike, i see you've made a few posts !   It's time to share your experiences with the group and some details about your car. I have some knowledge on the engine build but i'm curious about the rest.

Ron, I've been trying to get him to crawl out of his nuts and bolts and manifolds for ages to sit down and wright out what he has done and what has worked well and what not to ever do again.. Maybe now that he's getting close to done he'll take some time writing and not just reading.. Maybe some bragging too!!

Hi Ron, as you know this motor started out with a monster stick, mp's 590 lift for a street car. Ha, whats wrong with that picture?  I gave my friend full control at the engine shop and needless to say we had to re-do the motor.... So here is the break down on the motor now. It made some nice hp and tq .. This is going in a 68 charger:



440 bored to a 451
Ross pistons
Manley rods    Bought these cheap from a guy building a hemi. The 440 didn't dyno big enough for him. Oh well...
comp cam crb3 xe282s
1.6 Roller rockers
e heads.  no porting
old 440 Torker manifold  from the 80's
1 7/8 super comp hookers
750 mighty demon  mech..
410 gear    3200 stall
motor dynoed at 528 hp @ 5700  544 @4600

Ron I know my cousin Steve P sent you the dyno sheet. I cant figure out how to get them on here. If you still have them you are more than welcome to post them.

Damn it Sammy,,,  Now we can't shut him up!!  Hahahaha..............

Thanks for the info Mike, it looks like there were some nice improvements made with this combo, both in terms of power and drivability   .....that's what the dyno sheets indicate. I'll post up the results so everyone can see.

The original build was terribly mismatched and it's apparent. The 590 and Victor are way wrong for a 9.7:1 aluminum head combo and it shows on the dyno sheets. So bumping up the compression from 9.7 to 10.2 and removing a ton of duration actually produced better power numbers. I'm not surprised at all. The Torker manifold is much better suited to this build as well and the bottom end power is significantly stronger with that intake vs. the Victor. This engine will idle relatively smooth compared to the previous combo. 800-850 rpm in gear should be no problem.   

(1) the first graph shows the actual dyno numbers. The torque curve looks excellent....it's making 500+ ftlbs of torque from 3600 to 5500 rpm. That is ideal because when you upshift from 1st to 2nd and from 2nd to 3rd....the engine won't be hitting a flatspot or "hole" in the powerband.   

(2) the second graph is a comparison between the two builds. The red lines are the original build while the black lines represent the reworked combo. It's quite apparent that the newly tweaked combo is making more power everywhere throughout the powerband. This is a very good example of what happens when you go "too big" on the cam and intake manifold for the rest of the build.

Congrats Mike, that is going to be one sweet running car when you get her back together. The improved power and drivability will be a pleasant surprise.

hey mike, pretty neat set up. VERY close to mine.   452 (lowdeck) kb pistons 10.4-1 comp xe282s cam, ootb e-heads. 750 dp with holleys hp main body, tm-6 intake. im runner headman 1 3/4 headers but will be upgrading to a set of 1 7/8 hookers over the winter.

  anyway i got the heads changed to the e-heads right before the last race and took it to the local race track. it ran a 7.33@93.95   1/8th mile. the interesting thing (at least to me) is with online calculators the 93.95 mph come in right around 530 hp. i was kind of skeptical about that though.   anyway nice setup!!

Here's some pics of Mike's new and improved Bullit !  She's a beauty ! 

[8WHEELER]

SWEET, I think he might have an air restriction problem when installed

Hey Mike,, I think you neglected to mention one major thing. This motor was dynoed on 91 octane pump gas.

In Vegas the pump gas is rather crappy. Rick, (the owner of HBR Competition Engines), taught us about the turd mix they sell for gas. This was the reason for the low static compression ratio. Now if that motor were to have been built for here in sunny Florida where we have a good, solid 93 octane and we sit AT sea level,,,,,,  pump gas and 11.0:1 all the way and maybe another () ponies..  


So Mike, when are we starting on the blower motor??

[Silver R/T]

nice beast

[MOPARHOUND!]

Eddy heads are impressive.  They deliver as advertised.

Reading through your build, I was guessing 475-485hp, but then caught the Eddy head listing.

Claims of 50 horsepower increase are not off the mark.

Switched from factory 452's with mild porting/oversized valves to Eddy's on the 496, and the beast under the hood got a whole lot beastier, dramatic difference.  More than I expected.

Here are some Pics of Mike's car that were sent to me. The Charger is fresh from the paintshop and has a killer stance....and now the drivetrain to back up the attitude. Running hard and looking good doing it....doesn't get much better than that ! 

Ron

[Runner]

very nice car! 

[kamkuda]

Nice build. Nice ride

[Mefirst]

[Silver R/T]

good numbers

[Steve P.]

Spoke to Mike tonight on the phone. The motor is in the car and it should be fired up by noon on Saturday.. I can't wait for my next phone call!!!!

 Would someone post the whole cam part number? I tried the comp cam crb3 as listed and could not find it on there page. Had a bunch of crb's but which one?

Ron, how would that work with my 346 head and 9.45 compression?

Ken, the part number is 21-232-4 and it is grind # XS282S. It would work well on a 9.5:1 440 on the street.....Runner has this cam in his lowdeck 452 and it ran high 11's with unported iron heads. He's now into mid 11's with unported e-heads.

Here's a link to the Comp webpage for BB Mopar. Scroll down to the Extreme Energy mechanical flat tappet profiles and you'll find the specs for this cam.  

To run this cam you'd need new springs and the guides would have to be trimmed down for additional retainer clearance but other than that...you'd be good to go. Of course you'd need an adjustable rocker arm setup for the mechanical cam. The crane iron 1.5's wold be fine for this application.

Yupper, that's exactly the direction in which I am headed. Ron said he knew his stuff and we have the dyno sheets to prove it.

Did we ever thank you , Ron??   

[firefighter3931]

Hey Steve, no thanks needed.....just a few burnout pics and a big ass smile is enough   I'd say that combo is working pretty darned good. Compare the torque curves between the two builds; at 3300 the mp cam is taking a nosedive while the Comp is building steam. By 3700rpm the Comp grind is making 140 ftlbs of additional  torque over the MP590.....that is freaking HUGE ! I bet Mike notices a difference when he gets her up 'n' running....his tires sure will !  

Comparing the before and after numbers i'd have to say the tweaking was a big step in the right direction. More power everywhere and vastly improved idle quality/street manners. I'm anxious to hear how Mike likes it.  

Ron

Ps. Yours is next !

 Thanks for the link Ron.

Hahaha, your right Ron.. Only I have to sell some cars and trucks first.. You know the old saying, Money talks!!!!  Anyone want to buy a nice low milage Fifth Avenue?? How about a Ram 150??
NO RUST..........

[Steve P.]

Since this combo has been brought back to life in other peoples builds I want to say this. I have been along for some rides and driven VegasMike's Charger. I can tell you IT KICKS ASS.....  This motor is all power and pull from the first spark.  I know Mike is very happy with it, even if he does bring up building a blower motor at least once a month...    

Summer is damn hot in Vegas and the Charger doesn't get out much when the ambient temp is much over 100*, but fall is coming and Mike has got some new stickies for the beast.. I figure the next major kink will be the 8.75 rear end.  My money is on a new Dana by X-Mas...  What do you think Ron??
