My C4 HSR has arrived
As far as TPI motors go, I don't think there has ever been a better test than this with aftermarket intakes....

I would run the HSR, and might someday still, but I already own the Miniram, so will start with it on my big cube motor...... I think I am going to wait for somebody to have one just sitting around while they are awaiting their engine build or something and borrow it and do my own comprehensive track comparison test of the MR vs HSR on a big cube sbc...... I'll do the same with a Superram if somebody has one laying around, I sold mine a while back.
....but actually didn't do as bad as one would think. I was also lent an HSR modified to fit under the vette hood years ago to do a SR vs HSR test..... but I couldn't get the HSR to seal.... no matter what, it turned my coolant into a milkshake..... so I gave it back.... later on, I found out some of the intakes were designed for use with the Holley 20 degree cylinder heads... maybe I had one of those, I don't know. I did have it on long enough to take it on the street, and with zero tuning, for whatever its worth....it felt great and ran smooth. If you want to try a Miniram for a test, let me know, I have one with fuel rails, adj fp regulator and 58 mm tb ready to go.... I'll ship it out to you this week. But, I'll need it back sometime within the next month or two to complete my installation. But, if you're going to do it, do it right..... same track, similar conditions, no other changes and no bias..... I would be very interested in the results. I am personally only interested in track et results.... on the dyno, I think its clear, the MR nips the HSR at the peak, but the HSR wins below the peak..... but the real question is, which one wins the acceleration contest. btw, with your current set-up, I think the Superram would actually win the n/a et battle, but just barely.....loosen up the converter another 4 or 5 hundred and I think the others pass it up..... but just guessing.
Miniram woudl be interesting thoBut i have a cracked flexplate i believe and wont get that fixed till over winter. car goes into winter storage in a couple weeks so no more testing/fun for me. I appreciate the offer tho

I will add, i've seen a ported superram on a 406 motor with a 280xfi cam make over 400whp and its smog legal in california
had a good 40lb ft of torque on my motor too, which is insane as i put down a fairly healthy 380wtq
Intake will definetly be my first motor mod...then headers. Already added a catback.

Is there a link for the modded HSR?
Thanks
