I really think the new Holley Stealthram might be the best overall aftermarket intake if its officially available nowadays, but not sure. I know in the SuperRod test where they took a 383, trickflow cylinder heads and a comp cams hyd roller 236/242 cam, the HSR was the clear winner in my opinion. However, it is worth noting that they used the F-body version as supplied directly from Holley. I know the brand new version that will fit under the vette hood they have to modify the plenum..... assuming that modification doesn't hurt the intake potential, its reasonable to believe this intake might be the new in-thing. I'm anxious to see how it does on a big cube inch motor.... if I don't find any results from somebody else, I'll do my own MR vs HSR A-B-A test this summer. Does anybody know how much the new corvette friendly HSR cost ? btw, here is a summary of the SuperRod Test with these 4 aftermarket intakes: Superram: 480 HP @ 5600 rpm 506 ftlbs @ 4200 rpm 485 ftlbs @ 3500 rpm Holley EFI converted manifold: 493 HP @ 5900 rpm 480 ftlbs @ 4900 rpm 445 ftlbs @ 3500 rpm Holley StealthRam: 501 HP @ 6100 rpm 493 ftlbs @ 4600 rpm 460 ftlbs @ 3500 rpm TPIS Miniram: 505 HP @ 6100 rpm 470 ftlbs @ 5000 rpm 445 ftlsb @ 3500 rpm The MR nipped the HSR with 4 HP peak advantage, but gave way as much as 23 ftlbs of torque everywhere else to do it. The Superram was a torque monster as you might have predicted, but gave away power above 5500 rpm to the other intakes. I showed the torque @ 3500 rpm because its a really important rpm in my opinion. In my opinion, the Stealthram finished 1st in this test with the Superram in 2nd and the MR & Holley EFI tying for 3rd. But, the simulator backs that up as well if these motors are in an auto, 3k converter, 3.07 gears. But, its subjective. Just food for thought.... |
