Solid numbers 🔥

[@MRE_Motorsports]

Thanks man! Not terrible but room for improvement forsure.

[@SlowerThanU]

Which was overshooting? Dome pressure or boost pressure? If dome pressure then yeah you can mess with PIDs to correct, but if it’s boost pressure overshooting even though your dome is solid then PID for dome target won’t impact that. Can’t wait to see how it does at the track!

[@stevestauff2220]

Cool deal I’m getting closer with mine. Hoping I can get similar numbers out twin gt35s we’ll see but love the car.

[@MRE_Motorsports]

Thanks!!! I appreciate that. Good luck I hope you do as well!!

I had trouble spooling a 7875 on a 351. I don’t believe I was seeing positive boost until 5100-5200 rom which is almost worthless for a street car turbo 400. I don’t know if I have a leak somewhere or something else fd up 😔

[@MRE_Motorsports]

Could be tuning related or something small as a leak

[@timweb1510]

@@MRE_Motorsports wow, a boost or vacuum leak could affect it that much 🤔

[@MRE_Motorsports]

Yeah depending on how bad it is

[@logut80]

Something bad bad wrong! 351 Shouldn't have any issues spooling that

[@dixoncider7882]

For grins and giggles check your waste gate to make sure it has the “fire ring” in it it’s a common mistake for a waste gate to be installed with out it will give you an 1/16 to 1/18 inch gap all around the waste gate valve causing epic lag I may or may not have had the same issue with my s475 s10 I always joked it’s a Honda because life didn’t begin till 5250 rpm🤣

[@zx6r1320]

how much power can you push out of these 5.3 LS's with a forged rotating assembly I got a motor from AMS racing on the way he said it would take 1000 whp all day and hes even got some guy making 1200 whp

[@MRE_Motorsports]

They can make quite a bit. I built one for a local racer and it made 1350hp.

[@johnanderson6255]

@@MRE_Motorsports how many pounds of boost 🤔

[@MRE_Motorsports]

@@johnanderson6255 for this car or the one that made 1350?

What cam is in it?

[@1badombre82]

The thumbnail said stock 5.3 but it sounds cammed and that not a stock intake manifold?

[@MRE_Motorsports]

Stock heads,block and rods and pistons. Upgraded cam, valve springs and turbo kit.

[@1badombre82]

@@MRE_Motorsports thanks for the info. I've been trying to figure out what hp and torque can be expected and safe from a stock 5.3 with upgraded injectors under certain amounts of boost. Looks like 10lb boost is the highest number that is safe and probably will provide just over 500hp

[@MRE_Motorsports]

No prob

[@logut80]

Didn't sound stock idling

[@MRE_Motorsports]

Stock with cam and headstuds🫣 stock-ish I guess you could say 😉

[@straggler666]

Solid slow ass numbers

[@MRE_Motorsports]

😎 thanks

[@straggler666]

Ls mustangs are lame so who cares what you are saying right now...

[@MRE_Motorsports]

No one really. I like to hear myself talk tho. lol

[@straggler666]

You just ramble on and on... it's boring.. yes you have a chevy motor in a ford cause your to cheap to build a ford motor.... yes we get it...

[@straggler666]

And its not even a 6.0 either... slow

[@MRE_Motorsports]

Nope. I’m far too cheap for 6.0 money. If I had your money id burn mine.🤭
