Mini Ram Questions
i been thinking about getting a mini ram intake for my 85 corvette, i have ported, 2.02 valve heads roller rockers, mild cam custom burned chip, and a bunch of other stuff right now im running around 375+ hp with the stock ported inktake and it runs awesome, but since i already have low gears 3.92 d44, i heard the mini ram works really well with low gears, what do you guys think would it give me more hp, and is it worth it? right now my car pulls strong to 5500 rpm i heard the mr pulls over 7000 rpm!

If you do a search, you'll find a few recent threads comparing the Mini Ram / Super Ram / Stealth Ram. Lots of good info from people who are running those set ups.
That being said, the Mini Ram is generally regarded as a somewhat higher RPM intake. With a mild cam (as you mentioned above), I don't think you will be able to take full advantage of the Mini Ram's upper RPM capabilities. The Super Ram would probably be an ideal intake for your set up. There are pros and cons to both, as you will soon read about...

Even ported, the heads are too small to take advantage of the MR. The cam should be fine for it, but I would go a bit bigger if it was my car.

How many RPMs do you want to spin your bottom end to? If you feel comfy pushing to 6500 I would dump a bigger stick in it.
Do you have flow #s from those heads?
P.S. Not to poop on your parade I don't think with that cam, ported intake and ported heads you are at 375chp. Probably closer to 335-340, unless your heads are really flowing some big numbers.

i really want to get rid of my sr. mine is a `90 6speed would a mr work well with a 58mm tb, 224/230 cam, stock heads, long tubes, stock gears want to put in some 3.73. as for the super ram i just want to get rid of it i guess im satisfied with it over the stock intake off course but everytime i open the hood i say a silent prayer that i dont have to take it apart for any reason.

just curious why do you think that it would be hard for 2.02 valve ported heads, and that cam to support 375 hp? the chevy 327 with 360 hp i believe came with a cam nearly identical to the one i have, but my engine was built by watson and ruppel performance, he said the engine should be around 375-380 hp , the guy is a genius when it comes to engines and porting heads. so i figured i take his word for it, besides i been in several other cars, 2000 z28 camaro, 2002 corvette and none of them feel as strong as mine.

As far as feeling stronger, I suspect it does feel stonger than a 2000 z or 2002 vette down below 4000 rpms but after 4500 I'd bet that the vette or z would pull away from you.
These 2 dyno runs are the same motor. The lower hp is a bigmouth intake and the higher number is a Miniram. The only other difference is a hi flow cat convert with the Miniram. This motor has a set of Trickflows and a 219.
I didn't get to the dyno after I changed just the cat, but thru qtr mile mph I figured a 18 hp gain which would be around 15hp at the wheels.
The math I use is 20% loss for an auto and 15% for a stick. Since I am an auto I put my car before the intake change at 364 chp. This is based on my estimate of 292 rwhp due to the cat change up from the 277rwhp that the dyno sheet shows.
Since I'd guess my heads flow better than yours, my cam is a bit bigger and I don't think a ported stock intake will flow better than my bigmouth/tube setup that is what I am basing my 335/340chp number on.
There is some more left in this setup come spring with another exhaust change.

Not from that graph.
Also, the big low end difference is due to the torque converter being unlocked and flashing better low end torque for the Bigmouth pull. I locked the convertor for that particular Miniram run. Had I left it unlocked it lost a lot less on the low end than this particular dyno sheet shows.
Here's a couple gtech runs. The first one is the Bigmouth and the second is the Miniram. Notice how the bigmouth closes in at the 60mph mark but the mini starts to pull away as the speed increases.
And for the gtech haters, I ran a 12.58 at the track, pretty damn close to that 12.52.
The mph reads high but it seems pretty close in the ET department.
Run 3 was when the car was stock with a catback and pulleys.
