Thanks. It is nice to have a local CMR tuner who can sit in the car and take AFR readings! I need to install the wideband I have in my garage. Its been there for 2 yrs?
Greg, Chris, I may be heading to the strip in a few weeks to see what I can do on street tires as I have no DR's yet. I figure next year (or the end of this season ha!), I'll start looking at TQ convertor, rear gears and DR's.
I have to slow myself down lol! The modding to the house will slow that down. Building a deck, small storage shed and possibly redoing the front patio this spring/summer. That should keep me occupied!
lol, well we might have something coming up at cayuga in the next little bit. im waiting for details on it.
I went to DaSilva racing this morning and strapped her down on the dyno. I've got the files, and will post pics of the graphs later tonight, but suffice to say that my mods got me a peak gain of about 50 hp to the wheels.
Not bad for a mild cam and better breathing.
Where i was really happy was to see how broad the new tq curve is.
Number are about 265-270 hp to 315-320 hp, and from about 315-320 ft-lbs tq to 360 plus ft lbs of torque. Off the top of my head.
Pulls in 4th with traction control off, logging knock, rpm, pratio and the short term adaptives. Pulls started from about 2500 rpm and peak hitting around 5000 rpm but much better breathing up top even to 6000 rpm.
As a tuning tool, you can visually see Overkill's tuning really paying off with a steady AFR of about 12.6 to 12.8.
Next steps: install the MTCM, hit the track on streets or drag radials.
Based on my graph and from what I've learned from the theory, a 3500 stall converter would work well for me. FTI or Builder Bill?

Congrads on the numbers Renny!

The MTCM will be a nice touch. Especially paired with a 3500 converter, although IMO a little to high.
Stock catback, and stock drivetrain
Typing from a tablet, excuse typos.
^^^ now looking at that dyno, I would tend to agree, since the torque plateau looks like it starts around 3500 rpm. Perhaps a 3000 would be better.
Probably a good idea to send the dyno out to a builder for review.
congrats. i agree with fred though, a 3500 is a tad high. i'd go 2800 through 3200 for your application.
Okay, so my next question is ..... FTI or Paramount? I've heard great things about both, why choose one vs the other?
I'll be honest, the one thing that comes to mind via Paramount is Token's situation, so I'm leaning to FTI.
How high a stall is the V6 oem torque converter?
The 3.5L has the same tranny, and I believe its the same tq converter.
Talked to robsrt of Speedrated and I'm picking up an FTI convertor. Kent's PI was a great deal, and I WAS THIS CLOSE to jumping on it but I've read and seen so many good things about FTI, as well as robsrt did his homework already, reading the build, grabbing my dyno graph, etc. I feel like good things are coming my way.
Being home on Parental leave has led me to do some crazy things.
For example, I just purchased an FTI 3200 stall from Rob at Speedrated. We talked about my build, dyno sheets sent, etc, and I'm looking forward to getting this installed. Customer service was great!
Overall, I've got to say that most of the vendors I've dealt with here (Fargo59, Overkill, Adam @ Eastway, Jarz/Stu @ Inertia) have been great, and have all had great customer service.
Looking forward to FINALLY taking it to the track soon. Probably Saturday May 19, or May 26 for a test and tune at Cayuga. After getting some times on the oh so thin 225/60 street tires I have on, I think I'll be in the market for some drag radials.
ANyone? hmmm? I notice Discount tire has 17" Cragars for sale at $119. Would it be best to get DR's from there as well, or does anyone know of any used sets coming up for sale, relatively local?
Lol I'd say how about just buying staggered wheels and running a 275 or so on the back, for starters. Even if you found used SRT wheels which are 20x9, you can still safely run 245 or 255 up front, 275 or 285 rear. You will notice a difference compared to the 225's.
Here comes change....
