Looking for a secondary to work with my s588. I'd like to make 1200 hp without using a gate. For fueling I have 5x.022 24v injectors and will be sending my 215 out to be turned into a 13mm. Truck will see some street use. I've been looking at a s468/87/1.0 or s369/74/1.1.
 
In. Hopefully there is a good answer, I've been wondering almost the same thing. I hear that new 369 is nice, but is surely some sacrifices are to be made.
 
I'd go with a sxe66/73, or gt42 while using a gate to relieve the manifold charger or go with a box s472/96 T6 1.32 if you don't mind a little lag and want more of a competition based setup without a wastegate.

Those were my plans with that charger..

463/83/090 would get my vote, we put a 463/83/090 over a 588 kit together non gated and it rocked out, I'd say that setup should support 1300HP with supporting mods. Monitor your drive pressure if your spinning it over 4000rpm and go to a 1.0 or 1.1 housing on the manifold if needed.

Why do people ask questions they know the answers to? Yes, it has been plastered all over the internet, those were his.

I'm no high hitter or drag racer, bit I have experience with the 2 above sxe366 and sxe369 as a secondary on a 6.7.

I've run both with the .91 T4 housing and first off they both are great turbos, and have given me zero drive psi issues with 60+ lbs of boost with the 188/220 cam.

Now I originally had the sxe366 over my 6 blade 480 and it was spooling to fast for me and being I don't have my rods in yet I wasn't ready to window the block. So I picked up an sxe369 and just swapped the supercore thinking it was going to kill some low rpm power and delay spool...... well the opposite happend.

The very first test drive I did after the swap I was thinking to myself HOLY $hit is this right?!...... the truck had more bottom end, faster throttle response, and the way it pulled even without the primary really being lit was even amazing. I wasn't expecting the sxe369 to be such an animal in the secondary position, but I can 100% say the sxe369 is without a doubt one of the best turbos I've ever used.

The 6 blade 480 I have actually maybe a little on the small side for some folks power goals, but in my application the sxe369 actually smoothed out my primary pressures spikes and didn't loose any up top grunt and instead just opened up the secondary bottle neck.

The sxe366 is a great turbo though and both are a good choice.
 
If I were to do a big setup the sxe369 with the 1.1 T4 over a 488 or even a 591 would be fun.

Awesome info^ what do you have for fueling/tuning?

Fuel wise I'm light compared to yall. Let's not forget to mention an awesome airdog issue um battling dropping FP(regulator being dumb).

The tuning is pretty aggressive on csp5 from ATP (idaho rob), and it's just an 85% II with R1's. This will result in spooling arpund 1500rpm.

This was a 5th gear throttle feathering at 1800rpm (68fre)

I'm actually needing alot more fuel and runs wot 100% clean. Also since I have no drive psi issue I'll grow into 100% over at minimum and run a 1.0 housing. This will go on with dual pumps at the same time I put my rods in. Til then, I'm just a big *****!
 
The hardest I've been willing to push it was 65psi and Drive is basically 1:1.

6th gear is flat scary to me in this 12klb truck.
