Very nice. Awesome 60' also. Whats your suspension setup? Lowest I got out of my truck on nitto 420s, traction bars and ALAs was a 1.71
I probably needed more practice

Yes just fuel. 30% tips and a duel duel fueler with a 2.2pw loaded.
My eighth mile was a 7.49 so bye bye 7.70 index lol.
The suspension is stock with some caltracs and 420s air down to 36 psi.
I was cutting 1.7-1.7 60' but i wasn't launching hard... i bumped it up too 2200 rpms and gained a .40 of a second iirc.

Damn nice times. Yours is the first 4 door I've seen dig into the 11's with no bigger than a 72. Very nice
. Wonder what a reg cab could do with that exact set-up?! Might as well swap the 72 for a 76 and not bother with the 75..

I wouldn't run any more than 10 psi to the HPFP's, any more than that and the seals will typically leak on them. More pressure doesn't always mean more flow.

Just curious in you logic with not bothering with the 75? Do you think the 76 is bigger?

Awesome times! Really makes me want dual fuelers.

76 bigger compressor wheel but the 75 actually has a larger turbine

Ah. Didn't know the 76 didn't have the larger turbine.

Soo deciding to go with larger turbine vs. Larger compressor wheel..which to go with hmmmm.. And not favoring elite or rcd more than the other which would and of you go with? I know alot of people like each one so I'm not sure. Power would be the same for either one

You'll be losing power to high bp with the 76.. Good chance it will negate any gains made from the 1mm difference in compressor size
Maybe stock fuel would see gains.. Idk

The 76 has a larger inducer on the compressor. But the compressor exducer on the 76 is smaller than the 75... More than a mm too. Just posting what I know. I can't say which is better because no one has dynoed back to back with a swap of the two atmo's.
Nobody has back to back numbers so nobody knows for sure. There is logic to why each might have an advantage. I doubt we will ever see any back to back numbers but if that does ever happen, I will be studying the specs on each very closely for my own knewledge on turbos.

from what I've seen, people just do high powers. better all around package

A lot more money too. Not in the average guys budget when looking for a reliable, cost effective drop in turbo setup.

This is true. But if u can make 750 with a 72 what more does the average guy need?

What if I drop in a s476 billet with a machined exhaust housing to connect to the high-pressure turbo... Very very cheap

your back pressure will be insane because the stock high pressure cannot handle the flow a 400 frame charger can produce
