Jeep 4.7 Stroker Turbo Dyno Pulls
Newcomer Racing 4.7 Stroker turbo on the
Dyno in naturally
aspirated form for break-in and Dyno numbers. The 4.7 was
broke-in and ran with a 390 Holley, then for the last two pulls we decided
to try a 750 Holley to see if the 4.7 could take it and boy did it ever!
The power numbers were up all the way through the power curve we ended up
w/312.2hp@5400 and 330.5tq@4400. Dyno pulls were made from
2500rpm's thru 5500rpm's, it made over 300ft.lbs the entire rpm range. The
current Dyno numbers
are made by a Jeep 4.7 stroker w/ 8.43:1 compression, ported head and
intake, and a small custom turbo comp.

LISTEN TO THIS WITH HIGH QUALITY HEADPHONES OR SPEAKERS ONLY. Like
anything, it wont sound the same, or near the same unless you use high
quality listening devices. Turn the bass up and enjoy. Its not obnoxiously
loud at idol, and sounds pretty deep and smooth on hard excelleration, and
on deceleration(engine breaking) it sounds pretty raspy and bad ass. I've
never been one for an obnoxiously loud exahust, but I really love the sound
and tone produced by this muffler.
I purchased it at performancecurve.com. The owner is a vendor on
cherokeeforum.com and is a really great guy. The kit is around $100, but
shipping across the country was $50. Even so, $150 for a cat back system
like this is an incredible price.
