Dodge Challenger 6.4L gains 18 RWHP from Peak Speed Shop porting!

2012 Challenger 392 shows great gains from having intake manifold ported by Peak Speed Shop and adding 90mm Throttle Body:

18 Gain in Peak RWHP
26 Gain in Peak RWTQ

Good gains were seen throughout the power curve.

2012 Dodge Challenger 6.4L 392 Yellow Jacket. A tune was done prior to the "before" results to factor out the effects of just tuning the stock setup. Dyno was before/after test on ported intake and 90mm throttle body only.
Dyno-tune results provided by customer - Jefferson City, MO

Here is a link to the forum members thread telling about his results: http://www.challengertalk.com/forums/f170/ported-intake-my-392-a-122089/

I did this with Peak Speed as well and picked up about the same...I plan to go run on my usual dyno that I have used since stock and get comparison numbers since last time. Mine are a bit less conclusive though since I also made a tire/wheel change in back. But none the less...it's clearly stronger/faster now and this is very good power per dollar mod!
Thanks again Bob!

What is the turnaround for this service?

Sent from AutoGuide.com App
Currently able to do the porting within 2-3 days from the time we receive your part. We ship FedEx Ground (Continental US) which takes another 2-3 days to most locations.

At some point, depending on volume of orders, we may carry some cores in stock so your vehicle won't have to be down while waiting for your parts to ship back and forth.

With the big temperature and humidity difference in the deltas on the dyno, do ya'll think the numbers might be skewed a little pure is that taken into account with the dyno software?

That's one of the reasons we prefer back to back dyno runs. In this case, the time between dyno runs may have hurt a bit and temperature may have helped a bit. Third party non-biased dyno results from customers seem to be preferred by members of other forums that we belong to. We will pass along more dyno results from other customers as we get them.

Perhaps this is a better reflection of the cars improved performance..... Here is the seat of the pants reaction of this customer immediately after making the swap to the ported intake and 90mm throttle body:

“With 90mm tb and arrington/bg tune this thing runs like a a scalded dog first and second seem to be useless out of a hard dig. dyno is Friday of next week. but all in all it seems to be a success. Without the tune it seemed it lost some in the low end but with the tune I got that back and then some. I don't know about peak numbers but it sure has more under the curve.” Todd – Jefferson City, MO – Hemi 392 intake ported and 90mm throttle body
