When my car made 870 on this dyno it trapped 127 mph @3600 lbs 1/8th mile. Hopefully i can go 130+ now.

 

Nice #s! What's hotside look like?

 

Its an on3 t4 kit with a t6 flange adaptor thats about 6 inches tall to raise the turbo up . Twin Pte Gates

 

Stick car or auto with non lockup or lockup on dyno? Great numbers!

 

Great numbers!

interesting, a 6.0 on 2psi more, made 120hp more....I thought the spread would be MUCH greater. On the same 26psi it might have been 990-1010hp......making me rethink taking my 5.3 out now...

 

This 6.0 is a completely different animal . Will never turbo a 5.3 again . 680 wheel on 9 psi lol took the 5.3l 12-14 psi to do that...spool is way faster . Also gotta remember this is SBE . Not forged.has WAYYYYYY less timing in it to keep it alive ans still made way more power. Might be 2 more psi and only 120 wheel. But has like 13* in it vs 17-18 on the 5.3 at same boost

 

The difference is you don't run low boost and actually maxxed out the 5.3 so you saw the gain from more cubes.

 

Ive done all of them, but a 6.0 or hell even a 7.0 wont stop me from enjoying 5.3’s, especially SBE 5.3’s. Who cares what they make on less then gate, whole point of a 5.3 is to give it 35psi and not blow out a cylinder wall. And even if you hurt it you dont have a bunch of money in it so you dont care and drop another one in. 5.3’s are almost always more fun mainly due to the lack of give a fawk. Plus you havent made enough power to even hurt a SBE 5.3 yet

 

ill continue to have fun and enjoy my quick spool. 👬

 

While faster spool sounds great in reality its not all that much different, pretty much anything you can do to a 6.0 to increase spool you can do to a 5.3L. I tuned a 6.0L with an S480 and a 5.3L with a GT55 and while the 6.0 spooled slightly faster the spool difference (in RPM) is minimal, the 5.3L just made more torque and peak power. Plus spool time really doesn't matter when you can leave the line on as much as you can hook anyways. Either way, have fun!
