Default HSR or Miniram??

I want to either install a HSR or Miniram intake, and also a cam plus all the other parts required. Can never seem to find a LT-1 intake conversion intake.

The Car is my weekend cruiser. It will see the 1/4 maybe 10 runs a year and maybe 1 or 2 slaloms a year. I also use it once a year for Holidays. The rest of the time it is 80% City and the 20% highway trips of about 2 - 3 hours. I only put on about 3,000 kms a year on it now.

Does 1 intake suit my needs better than the other. I know I have to have the HSR modified. I believe the HSR will be a little cheaper price wise than the Miniram. Also what cam would you use, and what size TB on the HSR?

I've searched a lot of info on these 2 intakes, here on the forum and internet but still confused?? maybe to much info now..

Thank you in advance.

You would have to change the hood, or modify the hsr due to the height.

I've seen info on both and I was going to go SR until I saw the single plane setup. Now I really want to make myself one. Good luck in your decision and the miniram would would good for drags but it would lost alot of your lower RPM torque which would hurt you coming out of corners. I love low end grunt so those two intakes aren't my cup of tea but to every man his own.

Thats what I'm wondering about, I love the torque, but I want some more HP and willing to sacrifice some low end grunt for some more HP, but I also don't want to rev the daylights out of it to have the extra HP. Looking for some more umphf from 1,600 rpm and up.

Any other suggestions????

As its mostly city driven and not hwy, it might be preferable to run the Holley. Low-end response would be a little better with that one with stock gearing.

I'd run with a 224/230 duration cam @.050 on the Holley, but I dont see anything wrong with using a hotcam, or CC305. Just depends on whether you have emissions.

It'll need some heads or more headwork to flow what these intakes can though.

No offense, but from the way you describe you will be driving the car,
the superram would be better.

But if you are dead set on the mini or HSR and willing to do the work(and it's quite a bit), the HSR would be a good mix of long and short runner intakes.

I tried the superram and the HSR but not the mini.

You will not be unhappy with the Miniram. I've been driving one for 3+ years, very responsive, 23,000 miles total, 100 runs down the drag strip shifting at 6500, at times a daily driver to work, and a 2400 mile round trip one weekend to Indy and back where I got 24 mpg running the A/C.

I am wondering about cost. Mini ram with fuel lines and thermostat housing was about $1300 last time I looked. How much total for the Holley with a custom plenum and all ?

I am looking to do high speed road course events and trying to decide on an upper too. I do not want to have to modify my hood to get it done.

I don't have to worry about emmisions.

I think modifing the HSR and parts, is a little cheaper than the Miniram and parts route.
Super ram is getting harder to find also. That was my first choice for an intake. I had some head work done 6 years ago, ported and new valves, springs for 1.6 RR's and port matched to intake and Headers.

Also I'm thinking of having stock TB rebuilt and bored, is this enough or should I just buy a 52mm TB??? or is this to much.

If anything I may swap out the rear gears but not for awhile , I have 3.07's now. Hopefully this will curb my mod bug for awhile...

I would stick with the stock TB for now.

My vote is that for installation on a C4, the price difference between
a MiniRam and a Holley Stealth Ram is small. I'll even go on to suggest
the HSR may well cost more than a MR once the final costs are known.

When budgeting, remember to include the cost of a small cap dist, injectors
and the other incidentals.

Hey Vinny, I moved my fuel lines to the front of the plenum, I used a -4an for the return line and that helped,, the -4an 45-degree fittings were $16 each but it works perfectly.

I had to radius the fitting for the inlet line so the throttle body cable would clear but it works nice, l

A rule of thumb is that the return line should be no less than the
same size as the supply line, preferably larger. The reasoning here
is that if the return is small, then it may become the restriction
determining fuel line pressure instead of the FPR.

Well coincidentally the ID of the AFPR is the same size of the return line, although the -4an is ID is a little smaller.

Also ol'RJ is using the -4an return line on his Miniram and he ran a best of et of 12.03 @120mph, so, no issues as of yet.

We'll keep an eye on it!

Flow through an orfice is different than flow through a length of line.
There is liable to be a pressure drop over a distance and across
cumulative restrictions like fittings/turns.

I imagine that short of logging pressures, it is the kind of thing that
is hard to observe because if/when it happens, attention may well be
on more important aspects.

It is hard to argue with success.

RoT's are just that. Thought I'd mention this one for consideration.

Did you happen to consider trimming the fuel rail to move the fitting
rearward from the throttle linkage?
