I'm curious if anyone is running these turbos on a 4.6 based cobra engine? What kinda power are you putting down? How's the spool act? I've done a lot of searching and can't get a good answer on these.
I am running the 6466. Are you running manual or auto? They take a while to spool, but make great power. If you plan on street car bangin around town, I would suggest smaller hot wheel
I'm running a manual now with 61mm precision turbos. I'm running a Sullivan intake and the previous owner had supercharger Cams that aren't well suited to the turbos, so I don't see full boost until 5000rpm. I am switching to turbo cams with a tighter LSA so if I can avoid delaying spool more than what it is now, I'd opt to go big.
What's the details on yours?
What's your hp hoal with the 6062s?
Anyone else? The 6466 seems to be a big turbo and most are running autos from what I can gather.
Just run what you got man. The 6466's are some badass turbos and the car will be very strong. With the Holley, you can ramp boost and also set up some wheel speed sensors for traction control to be able to run all the boost when you want to. I can put down 1300+ on the street and stick it. And it feels plenty safe to me because the power is controlled and the car is stable. One thing I would consider is to just start planning to put a MVB auto in it and the fun factor will increase 10 fold and the car will be significantly faster. I too am 100% street car.
You guys are talking smaller turbos, I just bought some 6870's and will be shooting for 1500+ here soon. My 6766's are for sale if anyone is interested!
6870's

I have no idea how much boost. I've run 35+ psi before on the street so we'll see! Hopefully at 35psi, it's making 1500. I had a bent camshaft which ate a couple cam journals so I had to send the head to BES in Indiana to put some cam bearings in. While the heads were out, I had some additional porting work done which showed big improvements, especially on the exhaust side. I also have a new 6" Garrett intercooler being built as my Bell 4.5" core one was not efficient enough. Finish Line also refreshed my shortblock with a slight hone and some new pistons so everything is fresh.This guy is going to 6870s! That is going to be a handful. How much boost are you going to run and how high are you going to spin it?
Finishline is putting together my engine now, which should be able to hold up to a little more abuse that my current iron block setup. I know I should go to a mvb automatic, but I can't bring myself to do that quite yet. I'm running the Holley system like you, why did you go with the wheel speed sensor setup versus the driveshaft sensor? That is above my head, but I have a tuner that would be able to set it up for me that I've done work with in the past.
