How far have you pushed the 7675?

Post up a couple pics of how the current one is fitting. Fwiw I was able to fit my PT8285 in the same spot as my pt7675 but it was a bit tighter.

Im at the 650rwhp /12 psi mark right now, but I am aiming for 1000rwhp and from what I've read, its not possible with that unit

12psi is nothing on that turbo, turn the boost up before you start looking for a new turbo.

Ive gone over 152 running out of gear with a 7675 at only 15psi
It might not make a thousand but itll probably do close

Any reason behind the 4 digit power goal other than wanting the number?

Want to run mid to low 6 seconds in the 1/8 of mile

The pt7675 will hit mid-low 6's. If anything, consider a larger downpipe if you are currently running a 3". I only upgraded to the larger turbo because my friend had it laying around and it fit perfectly so he cut me a deal.

I have already made over 900whp on my 7675/5.3 combo. wasnt maxed out yet. may not make 1k on an auto. But will on a stick car.

Thanks guys! I already order my second walbro 400 and a hobbs switch to turn the second pump on when I hit boost and we plan on pushing it harder than 12lbs on VP race fuel and meth injection.. Hopefully I get in the 18-20psi range..

x2, doesnt even feel like it comes alive until 18PSI, screams to 20+.

More boost for sure. The PT 8847 uses the same H cover compressor but has a slightly longer center and turbine housing. That one will make quite a bit more power.

I think everyone missed the part where you are a 370ci. You will probably start fighting back pressure very quickly after you turn the boost up. That will be your biggest challenge.

Downpipe being 3" will prove to be the bigger restriction than the turbo on a 370". In my opinion that turbo has a lot to offer. Get a 3.5-4" downpipe and it will handle 20+psi well

What would be a 3" downpipe limit??

I don't have any concrete data to substantiate what I was running into but I was seeing diminishing gains after 16psi on my 3" downpipe. I feel as though i was choking on back pressure with a 5.7. The plan was that I'd do the bmr turbo kmember and run a 4" on the PT7675 but I decided if I'm going through all that I may as well use my buddies turbo since it was right there.
