I'm not sure if it's the elevation, or the dyno, or perhaps you're leaking exhaust or boost, but that looks kinda laggy, and it's dropping torque pretty hard up top so it can't be a very high flowing turbo. Maybe I'm missing something.
*edit: then again you're on pump 91 at elevation, so maybe I'm just spoiled by e85 and sea level. These new turbos are definitely interesting. |

Definelty does look kind of laggy. Are you sure you don't have exhaust leak? When do you make full boost on the street. How is the transient response of the turbo?

Triple ceramic ball bearing and turbosmart wastegate. Rallysport had good results with their stage 3 and I wanted something that would spool better.

Pretty solid numbers for 91 octane. I made 370 hp/375 tq on E85 with the same turbo on a stock motor 2005 STI with all the possible bolt ons. Boost was 20 PSI for my tune. I was tuned for a mix of summer and winter blend E85 though, so my numbers could have been better. My turbo is also pretty laggy compared to other stock location turbos. Doesn't get into full boost until right around 5000 rpm and the torque tapers off just like in this dyno graph. I feel like I should have just gone rotated with a Garret GT3576 but didn't have the money for a built short block. It's fun for the meantime, but I definitely see myself getting bored with this power soon.

Do you hear a dry bearing sound on shutdown?

I use a perrin FMIC as well, the perrin seems to have smaller diameter tubing then most FMIC. The smaller tubing would help with spool. When fully warmed up I feel like I hit full boost at 4300-4500 ish. Which is what I expected with a larger turbo. Iv had no issues so far or weird noises. The only issues im aware of are the first gens of stage3 (fitment issues) and stage1 trim ratio causing to much bottom torque. Last edited by Karyuko; 04-30-2015 at 04:16 PM. |
