Hello everyone, A little worried about the sounds I am hearing from my engine recently. Got the car near the end of last year and wow what a great car. Anyways weather was nice enough to drop the top down (mine is a convertible) and it sounds horrible. Intermittent tapping/clicking under the...

I'm looking at buying a voodoo sleeved block but I want to make sure RPG is a reputable shop before I drop 12k

Having an odd issue right now. LTFT both banks are going to +20 when cruising down the road at part throttle. I also get sporadic spark knock when im crusing at 2k rpm and lean into the trottle. They normalize when I go 50% or more throttle. I currently run E85 and have verified 85%. I have...

Hi all, Recently my gen 3 block seized in a 2020 mustang gt with the 10r80 transmission. I took out the engine and opened it up and I believe that the car swallowed in someway 7 quarts of oil and spun rod bearings. The oil pan ended up with rod bearings shavings and the vct Solenoids and even...

As the title says, I'm curious to know if anyone has ever dealt with Yard Smart LLC on Instagram for any car parts or engines? Instagram: Tiktok: I've been looking into them and there are several things that I'm interested in for my car but they don't have a website and can only message...

Good evening, My 2017 S550 5Lt Manual UK has been struggling severely. The car is totally stock except for a Borla exhaust. And K&N filter that’s covered around 5,000 miles. The car currently sits at 42,000 mile and has been serviced in the last 5/6 months. Around a week ago whilst cruising...

Hello, I have a 2016 Mustang GT/CS 5.0 V8 with MBRP exhaust, k&n air filter, remapped ECU, automatic shift. During last weeks, I was considering to install a supercharger, like the one provided by roush (or any other brand) that includes everything is needed for the installation. My only...

It’s only on cold starts and I don’t know if it’s something bad. It’s a 2018 GT

Hi everyone, I need help with my supercharged (with Whipple) 2019 GT350. I got it recently with the supercharger already installed. I took it to a mechanic for diagnostics and a Lund Racing tune. The car passed the 93 octane tune successfully, but unfortunately, the engine blew out on the E85...

Any clue what that rattle is? Doesn’t sound internal. About the 7 second mark of the video. Thought it was the heat shield on the turbo but it sounds like its coming from lower on the motor and only does it when I cut the engine off. Thanks in advance. 2017 mustang Ecoboost. Oh, I’m the only...

My car is struggling to start. Seems to have plenty of power as everything comes on electronically. Starter seems fine. Maybe I overlooked something? please see attached video for example

Hi Forum, Which is the required torque for the 2013-14 Coyote Head Bolts with the 11mm Bolts. I have only been able to find information about the earlier 12mm Bolts. Thanks in advance Ueberhopft

Good day, I have a 2021 mustang gt, 12000km. This morning on a cold start, the car is seriously struggling, It's only -10 C in my garage. The rev counter is just going up and down, the vacuum gauge is not stable at all, the car shakes while it does that, and the engine sound is not right as...

2016 Mustang GT Premium Convertible. Feels good, feels like it runs good but has a strange engine bump that's random and is mostly present when cold. The engine will very briefly shudder when it makes the bump noise. No ping sounds, just a low thump kind of noise. Once I've driven it some...

I have been saving up money for a second block to be built and I am not sure what direction to go. I see all kinds of advice on here for different blocks, companies, head combos and compression ratios but I am not sure of many with the requirement that would also let it use a stock tune It is...

Assembling my gen3 coyote shortblock. Any tips on cleaning the engine and best practices when re-assembling? The motor was a used motor I bought from another user. I’m going to leave the rings as the previous owner gapped them, but I am going to replace all the bearings. Also thoughts on the...
