Expected power with an Lsa blower on a 5.3...

Any luck on those numbers? Been watching your videos on YouTube. Car looks and runs great. Looks to be a fun car.. I got all my parts now. Do you think the Corvette regulator setup will work with DW300(340 lph at 100psi fuel pump) on 93 with the returnless fuel rail setup? You got all my answers dude..
Oh and I don’t see why not. As long as you dont need any more than the stock 58ish psi, it will work without a problem. If you ever need more than that you’ll have to replace it with an actual regulator.

First run of the day with the new rear and tires! Gearing is spot on, crossing the line at the very top of 4th. I waited 20 minutes and went again but the clutch slipped badddd. Its a twin disk mcleod with probably less than 10k on it. Let it cool and babied the launch and it held, but my 60ft was trash. Gonna wait another hour and try again.

much and it was spinning. Clutch feels fine now though, but I don’t trust it. Will need to updrade sometime next year.

I removed the solenoid all together and then connected the V side of the bypass to regular manifold vaccum. I left the bottom port on the valve open. At idle the valve gets vaccum and stays open. When boost comes up and vaccum goes down, the spring in the valve closes the butterfly.

Expected power with an Lsa Blower, now with a 6.0!
I’m back at it again. The 5.3 kicked the bucket after playing with the 2 step at the track. Im assuming either the meth injection hydro locked it or 15lbs at 2600rpm was just a little too much for the gen 3 rods... Regardless that little 5.3 lasted me about 6 years! Not bad for a 300 buck motor off craigslist.
Anywhos, here’s the new setup. Any guesses on power? The car is going for tuning in a few weeks.
Gen 4 LY6 6.0
Summit Racing Pro Ls Forged Rotating Assembly
12cc dished pistons, static compression around 9.1
Cnc ported/rebuilt 823 Heads, Ferrea valves.
1 7/8 Speed Engineering Longtube Headers
3 inch Y pipe into a Flowmaster merge, single 4 inch Mufflex out the back with a Magnaflow race muffler.
BTR Stage 4 PDS Blower Cam
Lsa Blower with a Zl1 lid, reinforced cooler brick, .500 lid spacer.
Walbro 525 Hellcat pump, Siemens deka 80lb injectors.
2.4 Weapon X upper pulley, 9.17 ATI Lower 8 rib, lsx concepts race drive.
Ported snout with a Nick Williams 102 Dbw throttle body.
5 inch short ram intake
10 Gallon ice tank in the hatch running through a 26x15, 2.25 core, Afco heat exchanger from a Ford Raptor.
Same Aem meth injection using 50/50 boost juice. I replaced the controller with one that uses injector pulse width, in case the boost reference controller flooded the motor.
Strange S60 rear with 3.73’s and a tru trac.
Strange Chromoly driveshaft.
Stock 94’ ls1 converted t56 with around 120k... hehe
I’m using a Holley terminator X Max this time and so far I’m blown away with the drivability of this setup.
Best run on the old setup was a 10.8 @ 133 as shown previously. Put down 530rwhp on a Mustang dyno, 620ish converted to dynojet numbers. The car weighed around 3800 with me in it on the 10.8 pass.
I’m hoping for around 700rwhp Mustang numbers on the new setup!

That's a nice combo of parts you have there. Thanks for choosing one of our Pro LS rotating assemblies for part of the build. Make sure to update the community with the dyno numbers once you have them.

LS swap
I have a Nissan Patrol 2003 I swapped the engine to an LS 6.0L with 6.2L heads and a 2.3 Whipple supercharge. I have faced belt issues like slipping and cutting, therefore I lost boost. I want a conversion kit from 6 rib belt to an 8 rib setup, Ending up making approx 12 psi of boost. Can someone please help me with this.

I would contact Whipple and see what they would have available.

I made it to the dyno on Saturday but I kept losing fuel pressure after about 4200. It would dive from about 70 to the low 40’s and go lean. I realized the 525 I picked up was only rated at 60 psi, so around 70 it only made about 370 lph. I really need to swap in a -8 feed line, but for now I’m installing twin Aeromotive 340’s. The second pump will be triggered by the Holley under boost, so it shouldn’t stress the pumps too much. I’m trying to make a rental on the 13th so the larger feed line has to wait for now. Anyway the car put down 508/577 at about 4200 with no timing so far.

Thanks. I did but at the time I had my intercooler pump mounted behind the license plate, so I figured the rs grill can stay and cover the hoses. Plus my car was originally a sport coupe, so having the rs grill is kind of an easter egg to that. Whenever I decide to swap it, the red bowtie is the one I’m eyeing.
