Precision Industries Torque Converter.....??

[bigbillybbs]

I have a 03 Marauder 50,000 on it.

I have a XCAL3 Tune by Reinhart, Dynotech Driveshaft and JLT intake. I am about to put 4.10s in when I get back from vacation and KOOKS headers CAT back.
The next thing I was thinking about doing is the Precision Industries Torque Converter, the one on Reinharts web site. I was wondering if this is a step in the right direction as the next mod I should do.???

Depends, If smoking your tires at will is your thing or knocking off almost seven tenths of your E.T sounds like fun then yeah I say go for it!
Actually the TC is the best bang for the buck. I have the PI 3000 stall and it made a huge difference in performance. You cant go wrong with that convertor.

Call Precision Industries and talk to them about what you want to do with your MM.

I did the converter and was worried at the time, but it is one of the best mods I have done. Very happy with it! Go for it!

[CRUZTAKER]

ABSOLUTELY.

It had to be the MOST noticable first impression mod I did well after gears and exhaust.

Do the tranny j-mod while it's out.
PM for the drawings if you need them.
Generally $50 additional bench labor if not doing it yourself.

NOTE: Replace fluids with oem, and avoid aftermarket synthetics.

what is a j-mod i am a newbie...

It is only the best transmission mod that is worth pursuing! Cruztaker has all of the info to do it yourself.

Definately makes the trans shift better.

You can alternately buy a valve body (http://www.bc-automotive.com/html/complete_4r70w_valve_body_kit. html)from Darrin at BC Automotive that has similar treatment.

I'm glad you said '03 model. Because the stock torque converter on the 03 is about a 2300 RPM stall speed whereas on an '04 model the stall speed is about 2700 RPM.

Folks generally use the 3000 PI converter but I chose a PI 3500 stall speed converter based on info from various manufacturers internet sites and from my tuner person. I love it, the off line performance is really great but the street performance is where it shines. Not often does one line up at the light and just nail it, it's usually a little nudge before one has determined that a race is on. The PI 3500 winds that 4.6 up into the power band in a blink of an eye.

My gas mileage hasn't suffered but my gas bill went up. Can't help wanting to feel that feel of a high torque motors high stepping out in front of the crowd. Prepare you budget.

If you haven't done so check your part throttle shifting from a standstill. Depress the pedal like you normally would then after a second or so floor it.
I don't think you should up-shift into second, you should still be in first.

Also check shift down from third at speeds around 30 to 35, the tranny should kick down into 1st not second.

If these things are so, then check them again after the converter install. It may require a retune of the electronic signals to the tranny.

Also consider an external tranny oil cooler kit. Higher stall converters generate a lot more heat. I had one put on my car $135.00.

Total bill, cooler, fluid, labor and tax = 693.00 not including the
PI converter.

This mod will put a smile on your face if your ready. If supercharging is in your crystal ball then I would go with a PI 3000.

When I went S/C I went from a 3,000 Stall to a 3,500 at no charge except shipping.

PI also inspected for free the TC when I upgraded my S/C and engine, just paid for shipping.

Pat, have you somehow confirmed this information? I cannot find anything to confirm that the 2004 came with a higher stall converter.

Edit: So far, Zack and Darrin have stated that the converters are identical, except the 2004 was "beefier".

Have you gained 7/10's on your 1/4 mile from the stall? Personally, the torque converter was one of my last mods and at best, it gave me maybe 3/10's on a launch close to stall. The only possible scenario I could see this providing said improvements would be a completely stock car, a launch off stall (@3500), and slicks.

Personally, the torque converter was one of my last mods

Thats why. Some on here went for a tune and gears. Then they did the torque converter next. Thats when they got a 5-7 tenth reduction in E.T.

The torque converter was my last mod as well, after tune gears, headers, exhaust, etc, and I saw a 3 tenth drop in E.T, just like you did.

My stall is a 3K.

A high stall torque converter will show its biggest benefits out of the hole. Saving a .1s in the 60' is worth more in the quarter; so the lower the 60', the quicker you'll go. My point is that you're not just going to gain 7/10's because you have a converter. To get said gains, it'd require a launch at or near stall and perfect traction (e.g., with radials or slicks). If this is one of your first mods, you're probably not going to have the rubber to see these gains in the quarter.

N/A I added a PI 3000 Stall and Cobra Exhaust dropping my best previous ET from 14.2 to 13.7 on KDW2 Tires.
60' /330' /1/8 /MPH /1,000'/ 1/4 / MPH Temp / Hum
2.168/6.062/9.214/78.53/11.95/14.274/97.05 - 60*/40%

1.966/5.686/8.768/80.03/11.452/13.743/98.33 - 65*/60%.

Generally yes a lower 60' will result in a lower ET. When you start comparing 10ths of a second there are a number of factors that can and do affect the remaining 1,260'.

No one, just looking for clarification. I don't like perpetuating the overly optimistic, advertised gains for performance parts. It should be clearly stated that these are under ideal circumstances, which few of us may experience. From Blackened300a, I was looking for clarification as to whether he personally experienced the .7s gain. Thanks Sailsmen and mpearce for your accounts on successes with the torque converter.

The advertised claim is:

"The standard performance gain reported is 2 tenths on 60 foot times and up to 3/4 of a second on overall elapsed times in the 1/4 mile."

[sailsmen]

Red, From what I know as respects the PI in the Marauder and I were writing the claim it would read "Performance Gains up to ......".

I like the PI product and service I have rec'd.

You are right about expectations, thats why it's best to check here for people like us to give the Real World 411.;)

When I was looking to pick up a convertor I was told numerous times in past threads that it will shave off up to .7 tenths of my ET. My only track runs were with the convertor installed so I dont have any proof that it knocks off .7 tenths I just trust the info that Im given. The night and day difference in the way the car performed after the install would make you believe it.

Understood and agreed that there's a noticeable difference. Thanks for the clarification.
