got told the other day that if i run a straight 3 inch pipe where my cat is that it will cause the fuel mixtures to alter whilst on boost. note i also have a dump and front pipe.

apart from fail an epa test would this have any detrimental affect to my car when it is running around 13psi on a stock turbo.

cheers

the 13psi will have a more detrimental affect to turbo life (as they dont like heat) as opposed to running no cat.

running no cat isnt gonna hurt the car as such at all.

disclaimer: no cat in a car is illegal etc etc

    • Everything I found online said never use it because it'll dramatically reduce belt lifespan.  No, but I have seen excessive v-belt tension cause the audible bearing noise from excessive radial load in things like alternators. So don't overdo it. Ideally you set it to manufacturer spec using a proper belt tension guage. I tried the "clicker" type gauges but those cheap things are trash. They read way too low even when you're careful.
    • This is kind of where I've ended up for the most part. It's easier for me, easier for shops that don't have to deal with my weird criteria/picky standards, etc.
    • Will do. Suprised if it's not the starter motor considering it's 30 years old. Will get a volt meter though. Battery is close to new.   Cheers for your help, always appreciated.
    • This almost never happens these days. No. Clean your battery terminals and make sure they are tight. Use sandpaper on a dowel if you have to, to get oxidation off the inside of the terminals, particularly on the -ve. Check the earth cable from battery post to chassis ground and engine ground. Make sure the contact surfaces are clean - including the threads on the bolts that anchor them - because that's where a lot of the contact occurs. Wire wheel on a drill is a good thing for this. Make sure the crimps on those cables are all sound. Assuming none of that causes an improvement: Check the battery voltage after it has been resting for a while. If it's at the lower end of the range, put it on charge for a while, then see if it will crank better.
    • I just checked my belt, it wasn't super loose but I could bend it past 90 degrees a small amount so I tightened it up and for the first time ever my car didn't crank first time, had to crank it again lol. Don't know if that was because I tightened the belt or if it's my starter motor going out (been having slow starts for some time). Coulda also been when I was recording I didn't crank the key properly and it didn't save the recording lol.   Is that a thing if you overtighten a belt it struggles to start?
