3300ish. As for what was left on the table I dunno. It was all done via a diffrent owner.

One thing helping it pull that high because at 8-10psi you are bypassing a good amount of exhaust past the turbine thru the wastegate. Pretty good idea really prob spools good and pulls up high too.

yes would be great to see documented real world results.

Josh, you gotta do this man

So I'm almost 1000lbs heavier and going 4-5mph slower. Probably making similar power, if anything I might be making a touch more. I think I'm just pushing this turbo to its max.

I am the only cheater here because mine weighs 2800 with me

look at skinnies, he went 8's on a TC 78 with a .96 on his 5.3 with around a 2500lb race weight

I fully support this!!

Josh, thanks for the advice regarding the TC76... For a 99% street car, 3200lbs, stock LQ4, would you say .96 undivided or 1.15 divided? Is there such thing as a 1.15 undivided?

Cheers,
joe

Johnv

for a 99% street car with T56 and stock bottom end i would be leaning towards the .96 ar , because you won't be running high boost, back pressure won't be such a problem, and with a M6 the quicker the spool between shifts the better.

If you have intentions of forgeing the engine down the track and cranking up the boost, go the 1.15

if you haven't already bought the turbo get the tc78....

Sweet thanks for the reply.

I have the TC76 already with a divided 1.15, was going to trade for a .96 with someone on this forum.

Looking for a reliable 500rwhp thru a T56...

Here's a question. What flows better...96 undivided or 115 divided?

The 1.15 divided will outflow the .96 undivided. I went from a .96 to a 1.15 on my TC76 and picked up 50 rwhp.

Interesting. I was told otherwise by a forum vendor, which I found hard to believe. Good to know, thanks.

i have a cam only 6.0l lq9 with a tc78 .96ar at 3000lbs it runs 142mph. with my d1sc it went 137mph

Johnv

i was told a devided housing flows around 10% less than the equivelent size open housing.

so a .96 open housing would be same as a 1.056 devided housing.

what would the spool difference be... ... i think my TC may be temperary...
move up to something bigger next year...

If you're wanting RPM I'd go with the 1.15 and knife edge the divider. I don't think it's going to pull to 7K with the WG closed but might get you to 65 with 346 CI. I rode in a 5.4L mustang with one and it spooled pretty good.

2600lbs here and I went 154mph on 18lbs, that is a stock shortblock 5.3 and stock heads also. I'm putting that combo in a heavy 4 door car to make daily driver next year and will probably be switching to the 1.15 AR to see what it will make. It made 686rwhp this year thru the stalled auto, 9" and 33" tires. I'd like to see ~715rwhp on the new ride on 18lbs through the stalled auto and 8.8 with smaller tires if I can get the new housing.

What is the most anyone has put down with the TC78?

im curious as well

I did 675whp with my current setup. Can't wait to see the increase with a 1.52 ar housing and possibly a larger dp. I'm keeping everything else the same except the rear gear.
