WItht he 2800 stall ikle has, he could probably do a 60-1 ptrim couldn't he?
Best Street/Strip turbo and converter for stock long block ?

Hmmm. My car stalls at 3k at 0 psi with the turbo you built for me and it seems perfect, almost a bit too much. Is it because of the more efficient compressor wheel?

2800 is less than 3000 and unless he used a Garrett .63 it would be a little laggy. With 2800@0 a stage 3 turbine with a 60-1 or t04e60 compressor will spool as fast as you can put your foot to the floor or possibly before you hit WOT. You have a gt35r compressor with a 76p turbine in a Garrett .63. That's a very fast spooling setup that will easily support 600hp. Fast spool to one isn't the same as fast spool to another. I usually refer to the worst possible scenario like the customers converter stalls 300-400 rpm leas than advertised, larger ex housing, timing and fuel not optimized on ramp in, cam selection/timing not optimal, lower than optimal CR, etc. Its possible to get a 76p to spool on a stock converter abs e.t. at the drag strip but would no doubt suck on the street. I've got a 9.5" PTC and it only stalls to about 3100@0 bit spools a 70GTQ very fast and the cam has more overlap than optimal for quick spooling. The timing and fuel as well as higher CR help it a lot.

Why don't you guys post vids of the spool up? It's and easy way to compare. When you run across these threads you may want to consider that you're talking to someone with a stock compression ratio, stock or 206 cam, stock ecm with a chip, and a converter that stalls at 2800 at best. All that needs to be considered.

10 * outside and snowing
I assume worst case scenario. With the common 10" or 12" restalled converters there's about zero benefit going to a larger ex housing than the Garrett .63 till the car can trap at least in the high one teens.jasjamz said:

Had a te44 restalled d5 and alky , worked good but changing my set up to a 6131 and a 10" lu ptc spec by Cottons, Just putting the trans and convertor back in today, hope fully I will feel a difference. Stock Long block !!!!

This is very true. I put a 6262 w/the .63 precision housing on a car yesterday with a restalled D5. What a disappointment. The spool up it had with the stocker disappeared. I drove it around to make sure it. wasn't something else.I was all set to put a RJC plate in place to fix the offset puck to port alignment. I pulled the downpipe to check the puck seal/ carbon print and its fine. Yes, that bad! I know a converter @3000 rpm will make it fun again. I think a 10" LU will be going in for the Spring.

I would expect it to spool very fast. The
10" PTC converters are built with off the shelf pumps/stators and the 10" will spool faster and couple less under power the higher the stall speed. I'd probably want 2600@0 with that turbo for really fast spool. It's the same as the 44 on the hot side. The gt35r compressor is a little heavier but not much. You will hit choke flow on the ex side before the compressor is even close to being done. I would expect it to pick up power over the 44 from about 4700rpm up if you run the boost in the mid 20's until it hits choke flow on the ex side

Yeah, I considered that option, but feeling it I knew it wouldn't be worth the time and effort. A converter will go in.

Bison what point do you think the choke point is on the hot side of the 6131? I'm planning on finding out than having you put a 76 exhaust wheel in and see how far she can go.
My DBB 6131 .63 spools very fast with a 2700 NL PTC 10". I'm going to see if I can get it to spool a bit faster with the xfi.

About 55-56lbs/min. 122-123mph trap speeds if the converter is coupling. About 30-32psi on an unopened engine. A Garrett .63 housing would spool it faster. You can nip it with the xfi. I can't put a different turbine in it if it's a ball bearing unless you have one thats ground correctly for it.
lol. 3 years ago I had it on a PTC 10" 3200... and it spooled slow from a WOT blast of 5-10mph on...no fun... That's why I will always buy a BB turbo for my mostly street driven car. BB turbo's only spool faster from 0-5psi BUT that's what I like for the
street.

I have yet to try a ball bearing precision. I have a friend with a turbonetics ball bearing 72p trim. However he has like a 3800 stall 8" converter so it spools quick anyway. Now that you mention it...3000 is what he will need at 0-1. 2800 won't make me smile.
