What kind of converter are you using?

What size stall is it?

Where did you get it from and how much was it?

Also how many of yall are using a T-Brake?
And how many have the 2.75 first gear?

Thanks
Albert

the ones i have doen and about to do are using a trans king j9 converter rated at 3500 stall.
the last car picked up a solid 2.5 mph using it.

personaly, i am using a transking 8 inch custom.
1/4 balloon plate rated at around 4800-5000 stall but this is used with a powerslide tho..

i dont see the need in the 2.75 planetary either.its a waste of money in my opinion

Im the one thats been talking to you about the 350 conversion. I called transking about the j9 and they said its only rated for 400 hp. Would it mess up if I threw a 150 shot of n2o on it? Should I have them put a balloon plate in it?

Thanks

they sold us that converter on a car thats got alot more than 400 rwhp..

i would say it would handle what your looking to do with it without any worries.

or you could step up to one of there custom 8-9 inch versions. and have it stalled to whatever your wanting. but the cost goes up to around 688 or so instead of the 457 price, but you get a free stall change with the custom converter...

lemme know...

Steve, how can you say that the 2.75 1st is a waste of money? <img src="images/icons/confused.gif" border="0"> Going from a 2.52 to a 2.75 is like going from a 3.73 rearend gear to a 4.07 rearend gear. If you have enough traction to hook it it's a big help.

I've had both and it made a big difference to me when I went to the 2.75 1st gear. It's not worth it for everyone but for your hardcore dragracer it's a must-have.

I have a Yank 245mm 4500 (4500 behind this engine anyway) and a T-brake in this TH-350.

Well Steve Sanders, considering I have a th350 and with a 252 first on a 346 stock block, I'm cutting 1.43 to 1.45's 60's times N/A off the transbrake @ 4000 rpm's so I would have to agree with Steve Franks on this one. I'll keep that extra money for something that I really need.

I do congrats you on your times though. You are tha man for now.... <img src="images/icons/smile.gif" border="0">

So, try it with the 2.52 and then the 2.75 as I have. Then report back. <img src="images/icons/smile.gif" border="0">

Like I said before, it's NOT for everyone but for the diehard drag racers it's a must have. <img src="images/icons/smile.gif" border="0">

BTW, the NA LS1 record WAS 9.97 before weekend before last. Now it's 9.95. Were I using a 2.52 1st gear would 9.95 be the record now? No, I wouldn't have even broken into the 9s with a 2.52 1st gear. Like I said, the equivalent of a 4.07 compared to a 3.73 rearend ratio is worth it to some people, not worth it to some others. No controversy, just a difference in perspective. <img src="images/icons/smile.gif" border="0">

Another tidbit, my 60 ft at Bowling Green with the 1.52 1st gear was a best of 1.54. I've since seen 1.39 WITHOUT the transbrake. Yes, there were other factors involved but the biggest was the ratio change, IMO.

So you can do a 1.43 60 ft with a 1.52 first gear? I'm here to tell you that you could be in the 1.3s with a 2.75. <img src="images/icons/cool.gif" border="0">

the big first gear planet is for people running smaller rearend gears

you could run 4.10s Colonel with the 2.52 and you'd more than likely run the same

Thank you, I am running 411's in my rear with a 1st 252 and I was happy with my first 60's and I know I had a little more left but after the tq arm broke that was it. I will be back on the track next Sunday. (Weather conditions are a factor also in the equation.) I think that the ratio 1st 252 and the rear 411's is a good combo for now and my 60's reflect that...

I'm already running 4.10s. To get the same 60 ft with a 2.52 1st gear I'd have to go to a 4.47 rearend ratio. Then I'd run out of RPM WELL before the end of the track. Not an option.

Default Re: TH 350 Users

are we going to get into the strength issue too?
i know what a 2.75 planetary set is used for.
i also know thats its not as strong as the 2.52.

heck, for the t400, you can get em as high as 3.00 these days.

the question remains, why would albert need the 2.75. its going to cost about 400 or so dollars just for the parts right?

stephen, are you saying that you had wished you had gotten the 4.10/4.11 ratio in your 12 bolt?

whats your rpm going through the lights?

Thanks Steve. Im just going to go with the 2.52. Ill save the $400 and put it in a 12 bolt. Im also going to order the j9 converter. How long would my 10 bolt last launching off the t-brake? Should I just wait to use the t-brake when I get the 12 bolt?


Thanks

i would not think the rear end would last any longer than the first attempt to launch on the trans brake.

what stephen is doing is using the 2.75 first gear to make the car launch as it had a 4.07 rear end gear. yet he is retaining some of the manners of a 3.73 rear since the second and third remain the same. correct me if im wrong.

you can achieve the same results as stephen if you plan the car for a certain tire and rpm you need through the lights.

a 28x10.5x15 et drag should hold all the power you can make. unless your into the crazy power levels
that gets 8 second 1/4 mile passes.

Stephen has 4.10's. He wanted the extra grunt off the line (with the 2.75) but not the extra rpms at the finish. Its just another option in gear selection. Sure it may be cheaper or easier for him to use the 2.52 with 4.30 or 4.56 gears, but he'd be on the limiter (or close) at the traps.
