Performance Auto Research

-
I seen guys like this my a whole life !! I wish these type guys would hangout with the LS boys !! Leave the Mopar alone !! Cause every time the LS boys mess with Mopars this is what I’ve seen !! Not sure why !! I’ve built Mopars, Fords, Chevys, Pontiacs, Oldsmobile, Buick , Briggs Stratton never had a problem with any of them !! It’s almost predictable when a gm guy starts working on a Mopar! That Mopar will never run !! Now why is that ?
 
Generally it's because they don't know Mopars. They put their "Chevy" knowledge on a Mopar and try to make it fit. It doesn't.
 
To me all nuts and bolts !! Just like transmission!! The guy who taught me to build Automatic Transmissions taught me just that ! And it made it easier to learn ! I honestly believe that !! I like all hot rods ! I prefer Mopars !! I like them all !
 
Performance research is literally 6 minutes from my house Bob balanced my rotating assembly for me before. He was a good guy R.I.P
 
I couldn't figure out what the point of the video was. Did they post a video of them looking dumb on purpose? Doesn't seem like anything in that video would make me want to do business with them. Usually guys who own a dyno know how to tune a carb but these guys appear to be mystified about what to do if the AFR isn't correct.
 
I watched it. It is like a train wreck, u can’t take ur eyes off of it. Kim. A classic example of more money than brains. Kim
 
It's all spelled out at the 10:20 minute mark, "I don't know a whole lot about these motors".
 
Won't rev past 5000 rpm. Where have I seen that before? Classic case of valve float because they slammed a set of roller rockers on there without knowing anything about proper geometry. It's just as important on a mild engine, as it is on a race engine. One thing he was right about, he "don't know", and "really has no idea".

To bad you can’t nut shell that into a paragraph that explains why beyond the fact that it’s all messed up.
:rofl:
 
Yeowza!!!

I’ve never seen a dyno guy hem and haw so much about making a hp/tq guess.

The 5000rpm wall just sounds like classic valve float/lifter pump up to me.
 
Here’s the follow up.

I got a chuckle out of the valve weight comment.

Looks like a nice clean dyno shop though.

Duane, now everyone knows your porting secret. Just take .200" out of the pushrod pinch, lol. If only it was that easy, right.
 
There might be an earlier “installment” of this build..... but here is one where the motor is being buttoned up prior to testing.

It seems strange to me that this build is such an oddity to a performance engine building shop.

 
I worked for a company name Automotive Research many years ago. They had people who were skilled in all makes of engines that were dynoed. I've been out of that game a long time, most of the guys I worked with are either retired, or passed on.
 
Initially I thought the power was pretty low, but who knows exactly what’s been done to the heads, and the shop apparently doesn’t own a burette, because they talk about how they don’t know what the actual CR is...... because they didn’t supply all the parts.

Looking through some of my sheets, I have a test on a mild 446RB.
9.5cr, Comp 280, stock rockers, 346 heads with an VERY minor bowl blend(about 1hr total for both heads), 6bbl, 1-7/8” headers.
499.9tq(just wouldn’t break 500), and 424hp....... so, not too far off this 451 build in terms of power.
 
If you watch the Performance Research guide and seat videos you’d see they have a nice white board at their disposal.
(They did a nice job with the hardened seat install video).
What they should do is have a list of all the build details on the board....... and go over the basic idea of the build right at the beginning.

After looking at some of the stuff they work on there, it’s even more puzzling to me how out of their element they “seem” to be with that 451 build.
 
IMO, they seem like a bunch of young fellas who (Again) IMO probably live in a 2 horse (Ford) GM town where MoPar people are far and few. I’ve read this kind of statement here before. So there contact with MP products is ultra low giving them ether zero or near zero MP experience.
 
There are some, IMO, minor different specifics for a BB mopar but in the end, an engine is an engine. I am flabbergasted that a shop such as theirs can't figure out why it breaks up at 5000 rpm. It wouldn't, or shouldn't, matter what make of engine it is. Ignition problems? Lifter pump up? Wrong valve springs leading to float? Cam installed wrong?

Post 12 answered your question for you.

They’re in Columbus Ohio....... you know..... where they hold the Mopar Nats.:thumbsup:

Based on the way the valvetrain sounds like its thrashing away...... I’m going to guess it’s a fast rate cam....... plus there was mention of 1.6 rockers.
If “normal” hyd lifters are used, that’s not usually a recipe for high rpm success.
