Poll: What would you rather see R&D on?

[blykins]

Building a dyno mule for myself and have an option of going a couple of different directions for data-gathering purposes.  What seems the most interesting? 

[Joe-JDC]

What data do you propose to gather in dyno testing?  Heads vs heads, intakes vs intakes, camshafts vs camshafts, or cubic inches vs cubic inches?  That would determine what shortblock to build in my opinion.  A good strong shortblock with compression necessary to stress whatever you want to test is a necessity.  I found that out when dyno testing heads, intakes, carburetors, headers, etc., on a Y Block build.  The shortblock needs to be as strong as the highest horsepower you want to dyno test.  Joe-JDC

Just trying some roads less traveled.   Short block is already sorted, cylinder heads/intake/carb is already sorted.  Just trying some different cam and valvetrain scenarios.

Since fewer and fewer people are using flat tappet cams these days, I'm going to vote hydraulic roller. I admit I'm probably going to go that route in future street builds also. I'm still not a fan of hydraulics though.

lower rpm , maybe 5200 max , good low end , for heavy cars , trucks , maybe tow truck , trucks seem to be getting more and more popular . 50's , 60's and 70's trucks . just thinking out of my head , uh box .

I think if you could develop a hydraulic roller that could go 7500 RPM's and live well that would be the
best route.  No break in etc and not have to fear possible SFT failures due to poor metallurgy or to wrong spring pressures etc.
I just think hydraulic rollers are the future.
Good topic Brent

We have no issues with hydraulic rollers and those rpms.  The issue comes with trying to pull "big boy" rpms with them.  I've seen some 6500 rpm hydraulic rollers here, but it takes some strategizing to get them to pull on up. 

I've actually got the hydraulic roller camshaft here for a higher rpm engine, but wanted to think outside the box a little more.

"Crower Cycle" was the first thing that popped into my head.  Not sure exactly why....

Do both, then, hombre.

Higher RPM hydro rollers.  Seeing what the LS guys are turning, it’s pretty amazing.  I know they start with lighter parts but have to be some lessons learned

another race engine ? I guess that is where the money is at .

You should know by now there ain't no grassroots in this forum. I mean, why quadruple the membership, right? I mean, we all love seeing engines that show big on the dyno and never see the insides of an engine bay, right? I mean, nobody actually drives an FE hither and thither, right? Daily? Oh, drat and pshaw.

Probably because he’s already done some

482's ain't grassroots, chillster. And where's the driving car the 428 went into? Naw, I want to see something like a 390 in a full size car with a stick trans or something.

[blykins]

Grassroots?  Can you explain?
