Hey guys, I just ordered the GTX3076R with the 1.01ar housing with a complete Sheepey Kit which will fit my RHD car.
My view was the 0.83ar versus the 1.01ar housing is the 1.01 housing will delay (lag) slightly but then hit harder and gain more horsepower until redline versus the smaller housing.
Has anyone had this Turbo who can compare the two housings in real life scenario?
Cheers,
Mark

Personally, I would only use the 1.01 A/R with a GTX3582R size turbo because you if wanted some lag and a big hit, well, the bigger turbo is better suited for that.

I was in the same boat when I was shopping for a new GTX3576 until my buddy Pang (PFAB) sent me this dyno sheet. This is from his car (AP1, stock motor besides head studs iirc) on an older GT35R. He said nothing was changed except switching the hotside from a .82 to a 1.06



After seeing this, I went with a 1.06

WOW that is a very steep boost pressure graph.
DONE I will stick with the bigger size that is exactly what I'm after

I will stick with the GTX3076R for it's throttle response but in the tuture I may think about the bigger GTX3576R or GTX3582R
