New Garrett GTX2867r

[Member]

My torque comes on hard at 3800 on the street. And if I lower the boost I will lose torque. I'm not as concerned with the overall power number as much as I am the power curve and how early it comes on. Your exhaust side is much larger. Which is probably why you are able to make that power. But as far as timing I have nothing to base off of. I went from 91 octane at 20psi and 11 degrees of timing to E85 and roughly 28psi and just kept adding timing until I felt it was making reasonable power. All of the tuning has been done on the street. All I did was throw the car on the Dyno and do pulls. And my point was you are comparing a GTX2867 to a 20g which are very different.

I was not trying to compare the turbos I was just saying I make more tq on a fast hitting small T2 turbo with out spinning on the dyno. If you don't care about dyno tuning then it doesn't matter but if you do then there s a reason your spinning on the dyno and it's not the tq in itself.
There is also not a very big difference in these two turbos at all.
20g is a little 52mm turbo. It is not a lot bigger by any means.
