Torque Convertor Choices
All,
I'm in the market for a Torque Convertor to compliment the setup in my sig. I've been in contact with both Vigilante and ProTorque. Both have different recommendations for stall speed.
Vigilante is recommending a 9.5" 30 spline convertor @ 2800 stall
ProTorque is recommending a 10.5" 30 spline convertor @ 2400 stall
The cam's advertised RPM range is 1600-5400. The torque curve on the dyno appears to become less aggressive in terms of angle of the line starting at 2800 and moving to peak torque which is in between 3600-3800 RPMs. I'll try to get the dynos scanned and posted.
I know a lot of guys here are running Vigilante and JD 90 383 was the only one that I knew of that was running Protorque. Looking for people's opinions on which way to go on this. I'm personally leaning towards the Vigilante based on the number of folks on this forum running that unit.
I plan to add a trans cooler to keep things cool. Does anyone have any suggestions or products that they've found effective in this area?
How do the 2800 Vigilante users like the results of the TC? How is street driveability?
Thanks for everyone's help!
Ron

I ran a 2,600 stall Raptor converter. It was cheap and worked very well, never had any problems and made a HUGE difference in the launch.

I know the protorque works with that combo :yesnod:
But i also know the vigilante works well too. I don't have any first hand eexperience dealing with vigilante, but i can tell you that protorque is very good to work with and somewhat local for me. You cant go wrong with either choice. I would stick with the 2800 stall in either case.

Thanks for the tip. I wasn't aware that they made the convertors for the 700R4. Looks like they cater to more of the LTx / C5 crowd. I will give a call tomorrow and see what they recommend.

I'd think 2800 is a little steep for an L98, even a little high for a LT1 if you're worried about street manners. I thought Vigilante made any stall speed you want, did they know you have an L98 when they gave you a recommendation?

I dont think you can go wrong with either, street manners would be the only thing that might bug me. Tranny will feel loose with the 2800, I guess it depends on what 60' you really want.

The guy I talked to (Joe) seemed very knowledgeable on the topic. Both companies asked a lot of questions which made me feel a lot better regardless of who gets my business. ProTorque is running about 7-12 business days to build the piece and PI is running about 3 days to build. I can wait in either case to get the right part for the job.
Thanks,
Ron

I don't want to turn the car into a drag queen (motor isn't that big), but some fun burnouts on the street and nice 60 times on DRs would be nice.

It begs the question of how much different is the 2800 stall than the 2600? Does the 200 extra RPM in stall speed kill the street manners by itself? I would have to guess not (it's just a guess).

Re: Torque Convertor Choices (RonRed89)
The actual stall of a TC will depend on the torque you put into it.
I put a 2,000rpm TC in my Vette and love it. Still tight on the street but I can pull low 1.8x sec short times.
I have a 2,400rpm TC in my IROC but it now flashes up to near 3k RPM which is just to loose for good street maners, IMHO.
I think a 2,400rpm stall would get you into the 1.7x 60' times with that engine.
Have you had your current setup to a local strip to see what short times it now pulls? Then you could pick a stall that would put where you want to be.
Don't foreget that in drag racing a street car it's not the ET but consistency that counts. If you get too hight into the power band you will play hell to hook up consistently without slicks.

I do plan on getting a set of drag radials for the track, as well as a Hurst Roll Control. Brake Torqueing it on the Baers wouldn't be cheap.
Outside of the track, the real reason for the convertor is that this car will stall when shifting into gear from park or neutral unless you give it a bit of throttle.
I'll post Wednesday's results if weather permits. I'm sure they will not be up to potential as I don't yet know how to drive the car on the new combo, but who knows. Maybe I'll get lucky.
Thanks all,
Ron

Re: Torque Convertor Choices (silver & red CE)
I went with a Yank Stealth 2600. I think, IIRC I got it for like $300 through a group purchase last year. It's a GREAT piece. I honestly couldn't tell a difference street manners, but my 60' immidiately dropped from 1.9x's to 1.8x's (and there's still more in it too, just gotta get traction!)

Re: Torque Convertor Choices (TIMSPEED)
Ron, Joe is the owner of the company. What you are getting in both the PT and the Vig is a well designed compromise between street & strip. Their converters are very streetable in my opinion. Mine seemed a little loose when i first got it, but after a few days of driving i dont even notice it. In fact i had it loosened this winter to over 3000. Still drives fine. There are other alternatives, some less expensive. I estimate the PT & Vig are about 1 tenth quicker than the off the self B&Ms or TCIs. I have no experience with Yank, but several people on this forum seem to like them. Good luck

Re: Torque Convertor Choices (silver & red CE)
[QUOTEJust my opinion, but I'd fix this problem and choose the TC that gives the best performance (as dictated by you, the owner). Why let a defect drive a choice like this?[/QUOTE]
Eric,
The TC was always part of the project for me. The problem is close to being fixed and will be with some more fine tuning. I'm moving to a higher stall TC to improve launches. As a side fix, allowing the engine to rev a bit higher before the trans engages gear should put the problem to rest once and for all.
Thanks for your help.
