Well.....Al's 12.58 motivated me to hit the track this weekend with my new Mopar TCM...lighter ROH wheels so all the ingredients were in place to break some records with the FRI Street Port / Sidewinder combo.

Result...

R/T .323
60' 1.78
330 5.202
1/8 8.028
MPH 86.57
1000' 10.48
1/4 12.54
MPH 110.44

I am not foolish enough to think this record will stand for long...too many strong cars out there to say where the records will end up this fall but it does demonstrate what one can do with a cost conscious, true bolt on, mds capable combination.

Notes: I ran all day with the Mopar Performance PCM/TCM combo trying to get the most from the newly released MP TCM which has a greatly improved shift management schedule...really tamed the Pro Torque converter...to the point where I couldn't load it past 2600rpms...with Superchips/Stock TCM I could load to 3200rpms!! 1-2 is now very firm....2-3 is strong.

I knew it was going to be a fun day when it turned 12.58 @ 109 right off the street without cool down. The car was running pretty damn consistent all day long (except for some wheelspin)....12.54, 12.57, 12.58, 12.59 @ 109-110 mph.

DA ranged from near Sea Level to +400....

Thank you for sharing. It is nice to see what a naturally aspirated MDS engine can do. 12.50's is damn fast for a street driver.

Can I ask...

How does the PCM and MDS like your stall converter?

Where the gains on the heads and cam worth the cash and effort?

Have you seen a supercharged 5.7 at the track and if so how did it do?

Thx.

Congrats Chris! That's some awesome times. Impressive to see you've gained a few mph, too, with those new rims and tuning and a little cooler air.

I think we may go down to Cecil next Wednesday and bring a few 5.7, 6.1 and maybe a 426 car to go test-n-tune. I'm sure Rob is in, too, and you guys can go grudge match some more since you're both running 12.5's now.

Hope to see you out there!
Joshua, HHP

The Mopar PCM/TCM really works well with the Pro Torque converter....actually made it feel less aggressive when driving normal but hits hard when you nail it. Not sure about MDS yet since Mopar PCM disables MDS... I will let you know how it does when I put the stock PCM back in with DIABLO tuning.

You sure you want to run again??:) :) J/K...its always a blast given how close the cars run. I would love to come up but too much going on during the week lately..... I am sure we will get together soon though as I plan on doing lots of testing when we get the DIABLO's in....maybe one of these Sunday's coming up.
