MBR vs BAE stage 5

Looking for info and specs on the Arias hemi and the MBR hemi with a 14-71 roots blower on alcohol. I have a chance on a great deal for a complete hat to pan Chevy hemi but I do not know anything about them the good, the bad, and the ugly with this combo right now compared to a brad 5. Any and all info would be greatly appreciated. Looking to put it in a 10.5 outlaw challenger on the east coast. Are there valve problems, bearings, how long do the rods last ect.. I know it all depends on the specs of the motor I would be getting. If this combo can make in the low to mid 3,000 HP. Thanks in advance for the help.

Thanks Keith Fedirko

 

I run an MBR Hemi and love it. Won the PDRA Open Ourlaw Championship with one that was 5 years old when I got it 5 years ago. Ran 3.614 and 200.17 in the 1/8 th with it. Seems to be as powerful as any BAE that I've run against. As far as toughness ....... Could not be more pleased, NO valve train problems....... Ever! Easy to service and maintain. Uses standard Hemi bearings for the rods. Has trust bearing in the rear like a Chevy, never blackened one, Hell...... I ran the same main bearings for 2 years. Shifted at 9600 Rpms.
Plan on dyno testing it in a few weeks to compare it against the latest , greatest BAE stuff. But don't be afraid to jump on it , they are great motors.

 

is it a Arias or a MBR or a Fontana or a Chevy hemi? there are sommmmme differences……all that I have ever had hemi style and a chevy hemi can be another orange not an apple…..hard to get main bearings if it has a 3" crank

 

Thanks Jody for the info just didn't know if I should jump on this combo or not. If you can let me know how the dynoing goes that would be great info to have. For the number on the motor I think I will have to go with it. Do you tune it also? If you can send me the info on the dyno my email is.

Thanks Keith.

 

Yeah like he said. What kind of motor is it?

 

Just email the customer that has it will post when he gets back to me with all the specs. Thanks again.

 

I think the mbr is almost 100lbs heavier than a bae. If it's not fairly current with billet block it can be a total mess.
They obviously make good power but have never come close to a bae in a outlaw screw application.

 

I think it's heavier, I'm gonna weigh my long block vs my buddies latest , greatest BAE. Then I'll know for sure. As for whether or not it makes more power in an outlaw car with screw, don't know but Timo H in Europe is the quickest TAD over there .....with a MBR motor. Maybe the problem is not with the motor but the fact that no one like Manzo has run with one long enough to find out what they really like. If it's a billet block and head deal is is better than a Brad 5 and more durable to boot. Like I said before, I've run just as good with my old MBR stuff as some of my competition has with the latest outlaw BAE style heads with a 14/71 roots. Not to mention the fact that I run my stuff really safe and fat to keep from having to work on it. No cad burned off the plugs, 850 to 950 deg egts and no squish on the rod bearings.

 

I looked pretty hard at MBR before I switched to BAE and I think its a good piece, but the weight and lack of available spares and data shut it down for me. The BAE is by no means perfect and we've dealt with plenty of issues that a MBR doesnt have. Unfortunately, a lot of this stuff is based on who won the popularity contest.

 

Exactly..... Had Manzo or Grimes run a MBR motor it may be a different story today. What has hurt the MBR is that it has changed hands a few times. Now the Bob Miner has the deal , he has really mDe the old Ariais /Fontana competitive.
As far as spares, I've never hurt anything at the track that a new sleeve and rod and piston could not fix. Plus being able to snatch a head off and leave the blower and fuel system on the motor is a huge time saver. Either one will win races with a smart tuneup.... If it's a good deal , go for it.

 

Do you run V rod bearings or the M?

 

V bearings.

 

i have a 10.2 mbr billet block . 4.5 bore. its a cn block, which is heavier than the new aj blocks, with no rails or caps its 131 lbs. caps weigh 10 lbs and billet side rails are 5 lbs each.

 

I have the same thing in a 10.7 block. Gonna weigh it before I put it back together. What does a BAE block weigh ?

 

If this engine you are looking to buy has the cast (Rhino) block that Fontana made, run away , as most of these have or will crack in the mainweb area. Fred Blanchard at B&B Performance is making a improved cast copy of the Rhino that has the HIP process done to it which should improve strength but at about 2/3 the cost of billet.
One of the main things about the Arias/MBR/B&B motor is that you can remove a head or the two without having to remove the blower or even loosen the belt.

The info on the engine is a Minor Brother racing it is all billet block and heads with 10.5 compression ratio. Had a little field blower and a big ugly on it at 29% over said it made 2860 hp. The motor is at the machine shop now and going through it and if all goes well I will have them dyno it and then I will know for sure. Thanks for all the help. looks like it will have a new home. Will try to post pictures of it next week when we dyno it.

 

update. just acquired a 4.5 bore 10.7 cn billet block. it is 167 1/2 lbs with 8 liners,caps, and side rails. this would probably be the heaviest combo block. it has not been lightened, the rails haven't been lightened either. the new aj blocks are 15-20 lbs lighter.

 

Complete head less rockers -44 lbs each
Valve covers. - 7.1 lbs each
Magnesium intake. - 29.6 with burst panel.

 

I just ordered a new block from Bob (MBR racing engines). He said that his newest block is coming in 20 to 25 lbs lighter than his old block that CN made, like the one I have now. 10.7 in deck
