crossdrilling helps the turbo last longer well worth the time to do it

For now, if I were you, Id back off on the starwheel. 1000 degrees is way too hot for 2 psi of boost.

ihave the mbrp 4in down pipe on a 5in pipe all the way back

---AutoMerged DoublePost---

i found i put my pyrometer befor the turbo so i read the temp before it goes into the turbo

---AutoMerged DoublePost---

i have my pyrometer in before the turbo so before it goes threw the turbo so i hear its normal to have a higher temp read there.

Ya a pre turbo pyro will read hotter than a post pyro because it cools down when it goes thru the turbo
