I believe those numbers include a ~1.2 correction factor.

Would like to see the 8374 graph with better cams. Looks like it makes good power, but, at least in the graph posted, it's not spooling as fast as I was hoping it would.

l8r)

 

9180 on the 2.2 is starting to make power 1.5k rpms sooner than my 6765 on a 2.0. Take out the .2 liter and it's still insane.

I wonder if the recirculation of the dump tubes help?

 

 

Hmm, that comparison looks funny, it looks like the 8374 was running at higher boost than the 9180 through most of the rev range. Come to think of it, if they were both setup to make 31.9 psi boost at 8500rpm, the smaller turbo would almost have to be running at higher boost lower in the rev range in order to be at the same boost at 8500, because it probably would have some fall-off.
Anyway, in this comparison it looks like the car would be actually faster with the 8374. But if they had set the test up for equal peak boost, the bigger turbo would probably look better. That's my guess.

 

Wow... seriously a game changer. I want one sooo bad.

 

First, does anyone know for sure what motor displacement is in the Sierra Sierra car?

Second, can someone post up some dyno sheets of 6765 or 6768 cars with similar motors in here so we can compare?

Thanks!

 

Its an 86x94 4g63.

 

2.2L - 10% larger than a std 2.0L

 

Anyone know of any 2.2liter dyno charts using 6765 or 6768 to compare? Heck, any size motor with those turbos would be nice to see.

 

Hit up Jeremy aka FatFab
I think the AWD guys have some dyno sheets floating around
Also probably hit up Patrick B. (i think its a 6262)
I think the ETS guys are running the 67mm on their X for a good comparison.

 

wow where are the updated dyno sheets with the other cams? its crazy how fast it spools up and hits torque so early even with a huge turbo

 

Damn I want this turbo....It's time to sell my New Gt35r turbo anyone interested 408.338.8774

 

I feel you'll be hard pressed to find any 700+whp turbo delivering 220whp (on any dyno) by 4000 rpm with a 2.2L 4G63. My twinscroll T4 comes within about 10% of that figure with my setup, but I'm not going to get 700+whp out of it.

 

Can't wait to get my hands on my 9180 and do a direct comparison to my 4088R which has been working very well on my 2.3...

 

Ted B has spoken, now time to sell our arms and legs for one.
