Switch C&L manifold for FRPP manifold?

[JoshK]

i am running a .81 on my precision. go with a .81 IMHO

I almost may just switch turbos to avoid downtime and go to a precision or turbonetics.

Edit. Just realized summer is pretty much over so there won't really be any downtime

Justin is who I deal with at Comp so give him a call to see what he says.

I've been emailing him back and forth. I sent him some pics and a video last night so we'll see what he says. I can't think of anything but the turbo that would cause it to spool so late. Jeremy is running the same hotside I am and the crappy intercooler is gone.

Dont go to a turbonetics. Your turbo should be under warranty so no need to spend more money.

how many miles on the turbo? when i first installed mine i was like WTF? this thing is a POS.....now i feel the complete opposite.

how fast it spools is relative to what gear you are in and the load on the engine...

it took 1000-1500 miles to get mine spooling the way it does now. your looks like it has not been broken in yet.

 

[Sprayer84]

Mine has 5000 miles on it.

Mine has 5000 miles on it.

lol....yup,id be calling comp and getting a new turbo!

Justin is sending me a label so I can get it back to them for inspection. It's got to be the turbo because Jeremy is running the same hot side without issue.

If I use the tip of my finger to spin mine, it spins pretty easy and just keeps spinning.

I'd go to a .81 hot side while you have it apart

I'm considering the .81 and the .70. With my goal only being 500 - 520. I'm think in can spool crazy fast with the .70 and still get where I want. I always have the .96 when I go forged. I'll see what Justin says about it.

If you go with the .70 I can almost guarantee that the top of your dyno graph will be down slope or atleast flat. It will probably make max power before the motor does and torque will decrease at the top of the power band as well. It will spool fast but will look like the graph of one of the ecoboost motors. You dont want a it to look like a mountain per se. You want the motor to top out before the turbo stops becoming efficient

I've had a .68,.81 and .96.......68 and .81 you will not notice a faster spool

i have a firends car with .81 A/R and its done at 6000 rpms, also i've seen cars with on3 performance turbo kit that is a small a/r i guess .70 also and its done past 5k, so for me .81 is the way to go on stock engine
