Wouldn't a MR be more friendly to a 6-speed vs. an auto? Would it be more susceptible to a "bog" with the wider spread of an automatics gear ratio?

 

Yes, I prefer to have a stick, but I am stuck with auto. I do have 3.75 gears to go with it, plus very rarely do I NOT shift it manually up through the gears, plus shift points can be changed if necessary.

Right now the stock heads, and cam will choke it off anyway, I am just p[putting it on to work a little better with my gears, but when I get a different motor, or build this one, then I think it will have been a good decision overall.

 

a good torque converter will help a lot with the mini...I believe there are some stout running auto equipped miniram cars out there with high performance torque converters playing hell w/stick cars

 

Yes, 12" wide rubber with genuine GM ZR1 wheels, (will sell the wheels).

 

So....I'm guessing you had them widened by 1"? Any clearance issues?

 

I think he means the tire is 12" wide, not the rim. He probably has 315 or wider on an 11" wheel.
(I am just guessing)

Hole shot, did you sell your black 85? I thought might have gotten a red one now.

 

OK, thanks. That makes sense. And I'm sorry for taking your thread off topic.

 

I think minirams work great especially on bigger inch motors. I have made over 500rwhp N/A with them.

 

Polo is correct - Rubber is 12" wide, wheels are standard 11".

I sold the black 85, bought red 87, had that for ~4years, sold that, bought black 87 vert 4+3 w/traco motor, sold it, and now I have had my gray 85 for almost 4 years. Not going to get anything else for a very long time.

 

So, that video of the mini is your old 85, or your current car? I guess I expected your current car to be a beast also.

 

The video is of my current car, 1985 w/6-speed.
The nose and rear have been updated with the 91-96 style.

 

Thanks for the vid, David! There's alot in this video that I could ask about and/or learn from on the eve of my motor installation.

With as big of a cam as you have, I wonder if most/all your launches are rolling because you need to get it rolling (and up in rpm) to avoid the low-rpm/lowER-torque band. IOW, get it revved up to the 3k+ powerband.

When I went from my original plan to do a psuedo superram 350 to a 383 using the same intake, my concern has been whether I'll end up with WAY too much torque -- and lose out on more usable high-rpm power. One advisor I had pointed out that I'll reach high rpms SO fast that a TPI would be nearly pointless. Your video seems to make his point quite well. It looks like you're barely staying in each gear (to redline) for about 1 second. Especially in 1st and 2nd.

One conclusion I could draw (after watching your vid), is that should immediately abandon my highly modified, long-vested TPI intake and opt for the HSR instead. That's because any add'l torque over what you're throwing down has to be pointless. OTOH, I wonder about your idle and off-idle and "driveability". It would have been interesting (to me) to see how the motor handles normal driving with that size cam and short-runner intake.

Another conclusion is that your higher gears provide the extra low-end torque that something like a superram would have. IOW, that lower 3.xx gears (or even 2.xx gears) with a torque intake would end up similar to where you're sitting -- sans the 7k redline.

Also, what's your code(s) issue? And, who did the tune?

 

RIGHT ON! Same (bumper) update I did on my 89. I also like the fact you did the 6-spd too! Nice looking car!

How long ago did you do all that?

 

Then you definitely have the right setup.

I just wanted to give a fair explanation of how there are different intakes which may be better for different driving styles.

The question: "Let's be honest, when you are just driving around on a Sunday, how often do you take it up to 6500?" was not intended to be rhetorical, but honest. This is just like picking cams, sometimes it isn't as "badass" to run a smaller cam but you may be much happier.

Hole-Shot, your motor rocks, I just wanted to give the OP a fair answer if they are trying to figure out which way to go.

Or really want I was trying to get across, to each their own.

 

I never had a problem with the low end using the mr. even from the first time around when it was a 350 build. On the latest build/set-up it is making 425tq. @2200 rpm, not bad for an intake that has no low end grunt. IMO, much of what was once "fact" regarding low end and peak power characteristics, can be associated with cam choice and maybe even more importantly tuning.

 

Thank you
