Will a TE63-1 spool up faster than a PT67?

[Jake]

If both turbos were P trim, .63 precision exhaust housing and same compressor cover, which would spool quicker and run the best on the street?

Truthfully, you could probably flip a coin. The 63-1 is kind of old school but it's a very good turbo. Personally, if it was me making the decision and I was buying the turbo new, I'd probably go in a different direction depending on what the rest of your combination is like.

I already have the 63, someone told me that the PT67 spools faster and makes more power than the 63. Kinda sounds like :bs2: to me :dunno: but I would rather hear it from people who know more than I do. The rest of the combo is a built trans with a 3200 lock up converter, big necked stretched intercooler, 60lb injectors, MPE (t.h. style) downpipe and a stock motor. I'll be getting some ported irons and a ported intake for it over the winter when I wont be driving it. I got the 63 used, but its at limit getting checked out so it should be good to go. I bought the 63 because I am trying to buy everything one time, not doing the 44-70 12 step program. I can grow into a big turbo, plus they really boogie on the top end. I have a stocker 86 GN if I want to have a well behaved street car. The T is the car that Im modding

The 67 is an awesome wheel. It does not have the high boost horsepower that some of the other turbos do, but it spools like a mother. The 67 is best suited for engines with ported irons or aluminum heads and a good cam. The 67 is not well suited for a bone stock engine. The 63 is kind of old schoo, but it is still a power house.

If you wanted to get 63 power (even more) and spool great, the GT61 is what you want. The GT61 will spool great with 3200 stall, yet it still moves a lot of air. The GT61 also works great at higher boost levels, which is great for stock engines ie: no port work or cam.

I just bought/installed VPE Stage 3 heads/intake and PT6152E. How well will it spool with a 3K stall converter? I'm asking because I found a good deal and bought a Power Raptor 3K stall 9.5/12 converter. I would think that the heads would help the turbo spool quicker and the 3K would be ok. what are your thoughts?

[NUKLRSIX]

The heads do help with spooling the turbo but you would want at least 3200 or even a 3400 for instant spool. You really won't feel a difference driving around town with the higher stall converter until you get on it and boost comes up. Over the winter I added GN1s and a 212-212 roller and found my 3200 9x11 still a bit on the tight side with the GT6152.

[Slow91z]

I have a GT6152E with stock heads and cam...3400 Stall insta-spool.

[TURBOTWISTER]

the plain and simple truth is the 63 "will" spool faster no doubt.personally i feel the turbo SLOW91Z is using is the best all around "street" turbo ever made.

my son's car has a very close combo to your own.i absolutely "love" it.on 93 octane pump gas,with a street chip and 16 to 17 pounds of boost and a 7 to 8 pound launch the car just went 11.6 at 117 with him driving.the car will be up on the VPE website shortly.he drives it everyday and it gets about 19 or so miles per gallon.you should be "very happy" with that combo.

nick,

I like it so far...It spools so quick I'm thinking about stepping up to a P-trim exhaust.

It needs to go faster! Paint doesnt equal horsepower. :yessir: Im picking the car up this weekend after the T63 and new CK trans. I cant wait. :racer:

[J Banning]

I'm happy with my PT67. To do it again, I'd definately get it from PTE with the .85 exhaust housing already installed (came with .63). I'm also now wishing that I might have gotten it with a Q trim exhaust wheel instead of the P... but time will tell when I get my new motor/trans combo in and running next spring.

With all other things being equal, the basic rule of thumb for spooling is this:

With larger A/R, wheel diameter or trim, a turbo will flow more air (which converts into hp) at the expense of spool (lag) time.

The smaller the A/R, wheel diameter or trim, the less air flow, but the quicker the spool.

Now, here's what makes things unequal:

Remember that when you refer to a 63 or 67 (which is the compressor wheel) they are available with different turbine wheels, so you have to compare apples with apples. the 63 was sold with either a TO4S 69 or 76 trim while the 67 can have either of these turbine wheels along with a GTQ.

A ball bearing center section can decrease lag time by an estimated 400-800 rpm. However, not all are the same. You can expect a dual ball bearing system to have less rolling resistance than a single ball bearing with a thrust bearing.

A vehicle's state of tune can affect how much exhaust energy is being produced (and thus spooling, resulting turbo airflow and then power). Say, for instance, that you're not lighting off all of the fuel that enters the combustion chamber. See where I'm going?

Just some food for thought.

This is true to a point. Some newer turbos use GT technology wheels that will spool better and make more power than the old T style wheels.

A ball bearing center section can decrease lag time by an estimated 400-800 rpm. However, not all are the same. You can expect a dual ball bearing system to have less rolling resistance than a single ball bearing with a thrust bearing.

I would still like to see some technically correct tests back to back. I know that the ball bearing turbos have less resistance, but I have yet to see this huge spool RPM difference in my experiences.

Would this PT-67 turbo be good with stock ported heads w/ bowl work and a stock match ported intake, 60lb inj, 9" art-carr 3200-3400 non l/u ??? I was also thinking about the TE-45a w/.63 percision hou. what do you think???

I am not a fan of going big with the turbos on smaller combinations. There are a lot of guys out there that run the TE45a on stock engines and get good results. To get these good results, you will need a good tune.

How fast do you want to go? I do not think that the PT/GT67 would be a good combo with what you have. The GT61 would be a better set up.

I also have the big P.T.E stock location I.C, how fast? low 11's, 10's? i'm also going to only be running race gas cause it is driven on the street about 150-200mi. per week and to the track very seldom. I'm looking for a turbo that will be very efficient with my set up. and that i'll have to pull the rear seat out of my a*s... from the line and from 65mph.

If you want high 10s reliably, the TE45a will do it with your combo. If you have alum heads and a big cam, the 67 would work. The 45a works better with smaller heads/cam than the 67 does. You will need 3600-3800 stall to spool the 45a well. 4000 stall would be the optimum stall. If you need a converter, let me know. We sell TCS converters.

Not to hijack the thread, but I will for this story. :)

Was at a shop where they do alota Stage II motors, and most all the cars are 10 sec capable. Guy has his GN trailered in, and over the phone says, and I quote *I want a car that will *scare* me*. Check comes in the mail for the agreed upon price, and the car is *built*. Guy and Wife fly in rent a car and go pick up the car. Wife drives back to airport with rental, guy leaves driving his GN home. Several hours later, the guys shows up, and goes, ugh, we need to take it down a *notch*. I was laughing so hard, I missed the part about how he did get home.....

A 45A seems a lil more radical as far as being a street car, IMO, then a 67. It may have been the tune, but the 45A took a milly second to get spun up compared to the 67, but, it was a thrill when it was whistling. The tune, converter, turbo, are all subjective, IMO, to what makes a guy happy. And converters are just sooooooo different from co., to co., about stall and flash RPM. The best thing to do, is bum some rides in cars with the parts you think you want, otherwise, you might not quite get what you want.
