2.8 mammouth boost level and RWHP on pump gas (93 octane)

[stop2go41]

I am running a regular 2.8 and am curious for the guys running a 2.8 mammouth on 93 octane what kind of numbers you are seeing? Just debating on getting a mammouth.

Boost will play a big part what numbers you can get on pump gas...to take advange of the mammouth set you will want to run lots of boost on e85 or race fuel

18lbs on 93 octane, 630-650 rwhp but I have some other work done to it.

I am at the same power level now I think the mammouth is not worth it for my application of 93 octane as I cannot turn up the boost high enough to take advantage of the bigger blower

I had 627/587 through stock GT axle back ( I have solid axle), I have a Borla cat back now so I am guessing I may have picked 5-10rwhp with that. Thank you for the response it has been hard to get a response on this topic. The KB site is full of info but not really applicable to what I am running.

I would agree, you could probably get quite a bit more just going to e85 on your current setup.

If E85 was available I would run it but nobody has it around my location. I have seen some crazy numbers on E85
