Tq convertor and WestersPCM

greentahoe · January 6, 2004

Im thining of doing a stall convertor and a Westers PCM

in my tahoe when I do the HD Hood. Roughly where do

you think that would put me?? 1/4 or even Hp?? Im hearing

about 30hp from the Westers. Will this be noticable since I

already have an Hpp3 which will have to be taken out. I hear

about .5 sec off the 1/4 times with a stall. What do you think?

A SC is a little out of my range right now.

Thanks

I also had the Hpp3 and was ok on WOT. I went with Westers 93 tune and was much better. No comparrison at all. The Westers seems to help a lot at part throtle also, where as the Hpp3 did not seem too.

The Hpp3 and the mods listed below did drop 1/4 mile times .7 sec. I have not been to the track with Westers yet.

Get a Yank TT3000. Im gonna go for a TT2600 cuz I think a 3000 is gonna be too much stall for me. The Yank verters are not cheap. The TT2600 is $650 and the TT3000 is $750. The stock verter is a 300mm setup. The Yanks I mentioned are 280mm. The STR (Stall Torque Ratio) is alot higher on the Yanks. Stock is 1.9 and the Yanks are 2.10 and 2.21 respectively. The STR determines how much the engine HP will be multiplied for more off the line torque. PI Vigilante converters are nice but I dont think they are good for a vehicle that is used to tow. This is where I think the Yank really shines as it retains alot of the factory towing capacity. You might have some traction issues. I said might. The HPP3 only makes changes for WOT, so there will be an improvement.

No high stall is gonna be good for heavy towing. . Westers and converter

should be baddass.

Well. Im never going to tow, but I want to keep it kind of simple and not get too wild. I know very little about stall converters. How much difference would there be between a 2600 and a 3000?? So you say Yank is the way to go... Just curious as to if anybody knew off hand about stock 1/4 time for a tahoe and then could guesstimate about new ones. Sorry, I feel a bit lost here. Thanks alot for the responses.

Not a whole lot of difference besides the STR numbers. The TT3000 is just a restalled version of the TT2600. And the 3000 is gonna put more power to the rear wheels. But its gonna take more pedal effort to get things moving. I wouldnt go any more than 3000 in a truck. Thats just my 2 cents. I talked with a guy that just put a PI Vig 3200 in his truck. He likes it, toasted his tranny, but he likes it! He just had too much fun running around town stalling up it at stop lights and hammering the hell out of it. Id say you would be good with the TT2600. The reason I say go with Yank is because everybody swears by ther verters. I havent heard a negative comment about any of Yanks products.

On another note, the converter out of a 2003+ Trailblazer with the inline 6 can be used believe it or not. It will bolt right up to the flex plate of a 5.3 and stall to 2600RPM. Not a bad increase if you can get the converter through a GM source at a good price. I might try that converter, I havent decided yet. Im sorry if I got you all confused. The whole converter thing still has me somewhat confused. Thats why I havent made a sure decision on what to get.

Im not sure how well its gonna drop your 60' times. But there will be a very evident decrease in your 60 foot times with a new converter. Your E/T will be lower too. Just as long as you learn where the sweet spot is on your 'Hoe. Practice your launches so that you eliminate any slippage. When you get that down, and you keep wheelspin to a mimimum, your truck should pull hard down low.

Should I add a shift kit as well since they will already be in the tranny for the install? Is this necessary? What do you think installation will run roughly?

PunchT37 · January 7, 2004

They don`t have to go "in" the tranny to install a converter, just move it

away from engine.

99Silver6.0 · January 7, 2004

Punch beat me to the punch!! They dont have to break open the tranny to install a converter. Just drop or pull the tranny back. Yes you can put a shift kit in if you like. Id recommend the TransGo.

If I could do a servo, do you think If I had some help I could do this without having to pay someone to do it. Ive got a limited amount of mod money right now and I want to get as much done as possible as soon as possible.

You can do it yourself. The converter wont be too easy on a 4WD Tahoe. But on the other hand it wont be hard. This is due to the fact that the transfer case has to come down too. It isnt bad but it makes it a little more diffucult to get the tranny out. Just take your time, get someone to help you. You could knock it out pretty quick. The servo is easy to install, it can be done with the tranny in the truck. But if your doing the converter put the servo in while the tranny is down.
