If the stealth is that much better than the MR for lower and mid-range, then it might be VERY worthwhile to give it a better look. However, unlike alot of guys, I happen to want to keep the EGR and air pump. I'm certainly not about to buy all this stuff now as we're down to 28 hours a week at work and they're asking for more lay-off volunteers. But nothing can stop me from formulating a plan for the future.(heheheh)

Aardwolf; The SR IS a great intake! I don't see many superrams coming up for sale anymore, and when I DO find them, I've been a day late or dollar short.

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....
