On e 1 run it ran 11.50 at 119. Want to get into 10s. Any ideas? Rick

Rick,

Do you have a TE44 or TE67, I am a little confused?

Start another thread and I'll tell you what it will take to run mid 10's with a mild tune.

Ask and you shall receive.

If he has a 6776 he has plenty of turbo. The converter will most likely need to be addressed. If he's looking to drop some coin and only wants mid 10's the 6262 will cover it and spool slightly faster than the 6776. If he went with the ball bearings it would be even better. The $ spent just goes up. I've seen journal 6776 turbos spool well on the street with an 18 blade ptc 9.5". He will capture a lot of e.t with one here. At 25psi/22* the car should run 10.50's if the tune is there and he can leave hard. Valve springs should be investigated.

 

[Nick Micale]

This is a classic example of "throwing" parts together, and then wonder why it does NOT perform.

No way in hell is that 3200 stall converter going to let the 70 turbo do its job. Everything but the converter is in place to run low 10's or better, be killer on the street.

Why such a low stall converter, we have GN's running a 4500 stall on the street with a 70 turbo, and will kill any opposition way beyond the speed limit.

You are dreaming if you think a 67 turbo is going to solve your problem or be much better. A 44 or 49 turbo would work with that converter if you are wanting to slow the car down for the street.

How much boost on your 119 mph pass? 60 foot time?

I put the stroker in last year and took the tranny out because of the tans getting hot and slipping. The extranny builder said it was ok to put dex-VI in...Wrong.I took it to Vince and had him go over everything and sent convertor to get restauled to 3200. I kept the TE-67 from Limit in to see if things would work,they didnt. Now I want to change the turbo to work with what I have (with all due respect ,didnt throw parts together).

 

[John Wilde]

So I will throw this out there.
You can change the Turbo to work with your Converter or change your Converter to work with your Turbo.
Which approach do you prefer?

1. Test the stall of your converter and report back to this thread.
2. Your existing turbo (if it is a 6776) should work with a 3200-3400 converter especially with the extra cubes.
3. Maybe this is a tuning issues and you don't have to throw parts at it.
4. If not you could send the converter back to get more stall
5. Or you could sell you turbo and buy something that will work better with your converter but still meet your goals.

 

[sscamino]

Sent the turbo back yesterday , they said will make what ever I want or trade.I want smaller ,so it will work with what I have. After this ,money is an issue.

Nick, I just want to clarify. Are you saying that a 3200 convertor is not enough for a 6776 s cover? I am putting a combo together and would appreciate your input. I have been told by several people that is the right fit for that turbo.

 

[turboclam]

My current combo is a GN1 headed, 212-212 roller cam, stock stroke 109, 6776 ball bearing turbo and a 3200 stall convertor. I really like it for the street (spools quick) I would think with what you have a little more tuning and it would work well for you.

 

[GNVYUS 1]

How does a 252ci with Ported Irons have trouble spooling the old TE67, you obviously have issues somewhere else, tune, converter and/or some aspect of the vehicle is not performing 100%.

Yet you sent a functioning turbo back to be rebuilt into what, a smaller less appropriate turbo for your combo?

You never replied back as to what Zero psi you're footbraking too, never mentioned anything about the tune or any datalogging etc so why spend $ on rebuilding a perfecting fine and appropriate turbo without data to back up your current situation?

My approach on building a combination changed years ago about converters.

When I had to borrow a converter to make a race, I used a 5500 stall to replace my 4000 stall, and my car performed much better.

I did have it tightened to 5000 stall where it has been for years, and can leave with any big-block car off the line on a pro light.

On a street car, too tight easily smokes the tires, instead of giving you good traction.

I prefer to go looser rather than too tight with converter stall, especially with larger turbos and a performance application.

My opinion, most owners and people giving advise have little personal experience with converter selection, and almost always go too tight.

Just want to add, my turbo is a 70 BB.

 

[JT'sV6]

Look into a trans brake. I agree, theres no reason you cant spool that turbo with the cubes your runnin'.

 

[QUIP'6']

rick had a 3600/3800 in before and it spooled the turbo crazy fast and traction was an issue also drivability on the street.sent it in for a restall and it came back at 2800 at 0 psi and 3200 at 5 psi as some converters are rated. as for the turbo he has had an issue every year with it going bad. john craig rebuilt it and this time it locked up after less than ten runs. the 11.50 at 119 pass was on 18 psi.

stroker

How much boost on your 119 mph pass? 60 foot time?

That was 18# and 5# off line 60ft 1.79

 

[Phoneguy]

You definitely have an issue here. My 249" stroker with a 72mm turbo launched at 0 boost cut a 1.64 60' and went 6.91 in the eighth on pump gas at 103mph with 22 psi and 21* running 10.0 a/f . You have the cubes to spool a much larger turbo with the right converter and tune. Listen to the guys that have been there...

[Ed Valvo]

Try more boost? Tightening the wastegate rod if you have a THDP will help it spool better since it will be tighter. If you have a TE-67 turbo, it's just starting to wake up at 18#. What RPM are you shifting at and what RPM are you spinning through the traps?
