LLY: injector/turbo matching

[jdlover1]

I am getting ready to pull motor out and change a bunch of stuff. Right now I have 60 overs with 75mm turbo. Will 100 overs match well with my current turbo and run that till I'm ready to go better? Or go with my other plan get 200 overs tuned for my 75mm and then buy bigger turbo in the future.

You can always tune them down. In my opinion, I'd go with the big injectors so you have the fuel when you're ready.

Don't go to 200 overs unless you want a competition truck primarily. You can't always tune those down enough to be happy with street driving.

My 125% overs are doable for daily but borderline. Rarely would you ever need more than that.

Go with 100 overs on the street, you can safely make over 1k at the wheels and the truck can still drive on the street relatively smoke free.

This is a 100% sled pulling truck. I'm not worried about street drivable.

That's a different story altogether. I would go with at least 200 overs minimum.

200% and up exergy have the bodies modified. I'm sure s&s and others would be the same

I talked to exergy and they told me 250 and up is when they modify the injector bodies

Ok, good to know. Was told by a dealer, member on here also. Either way, if its a puller only, i'd go bigger than 250 even.

Randy Overton is running 250% on a 4.1" single Turbo... But I am running 400% on a 3.0x4.4 hx82 charger, I run a 1700us tune, lol... I just ran a 4.1x4.4 Columbus Charger off my friends 4.1 Limited ProStock John Deere... I ran a 2100us tune and had plenty of Fuel... With a 3x3.6 hx60 back in the day, I was running 1400us...

Bigger the better IMO for sled pulling!
