What would be the expectations for gains of going to upgraded turbos on a Stage 4+ build (CAI,downpipes, exhaust and tune)?
What turbos are you running?4DRHTRD said:There are 3 options (as of today hopefully)
1. Turbos Direct via my company with stock sized (48mm) billet compressor wheels
2. Tial via Livernois with 52mm billet compressor wheels
3. ATP turbo +1 and +2 turbo upgrades via my company (or direct)
We are lucky that within the last year these options are available. I have to head back to the dyno to do a post turbo upgrade check, after I installed mine I had boost leaks like crazy and couldn't resolve them, the new hot pipes has finally taken care of it. The only evidence I can give currently is my car ran 12.4@109 on the new turbos with only 17psi and 5800' DA when I last went. I don't know if I can make the track again before I do the new turbo upgrades but will definitely have dyno done with current setup.
There are three guys on the Tial turbos (I think) that I am aware of, Darrelli has posted dynos somewhere but I don't believe they have attempted to truly max out that upgrade but I believe there's a 500WHP out there on these turbos.
The ATP + 1 and + 2 turbo setups will be going out either today or first part of next week to myself and BPD. I am having mine installed immediately and will report back as soon as I can. ATP is also putting dyno and track testing findings out when they launch according to the info I've been told. I will also be dyno testing and track testing ASAP after getting these installed.
If you had to guess, what is the horsepower gain for the turbo upgrade you went with?4DRHTRD said:I have #1 currently and #3 +2 turbos in the next next couple of weeks.
I guess I am just going to have to get over my fear of using 100% meth the same way I learned to get over my fear of nitrous.4DRHTRD said:I would guess I'm right around 450WHP right now on the bottom side of guessing. Optimistically right around 500ish but I'll find out next week.
I am going to say no way possible to hit 11's on stock fueling, you're out of fuel and require some type of fuel system upgrade either Meth to augment or an in tank fuel pump upgrade to help out the DI pump.

Also why do you think I'm at 12.0AFR I've posted tons of videos with Torque app running I'm at 10ish AFR, luckily E85 doesn't lose power like gas does with too rich scenario like gas does. I'm trying to get mine right at high 10's now with some data logging but having some issues with fine tuning on the current aux fuel controller. This is an older video but on new turbos and aux fuel system and 50/50 E85 with old fuel pump/fuel cell under the hood.
Boost leak fixed
But the key is he wants to run 11's without meth, can't be done IMHO and that's what I was saying. You need a way to supplement the stock fuel system to get to the power levels required to get it done. I'm betting that if you put 108 unleaded octane in your car for safety and unhooked meth you'd hit fuel cut. Love to see a log of that!darreli said:4DRHTRD said:Darrel do you think you can hit 11's on stock fuel system?

I think I can...I think I'm already there honestly. It's more so traction and torque converter for me. I think if I lived out east I would've ran 11s last year and I'm still on the stock fuel system. Do I think you can do it without methanol or nitrous...no.
I think the limits haven't been reached on the stock fuel system or the stock engine internals. Only time will tell
Whoops, I edited your post instead of quotingdarreli said:Oops...for some reason the second part of your post didn't show up on my phone. Were you running that rich prior to your fuel system upgrade? If so, my mistake
Just so you guys understand Bob is saying he was spraying meth, not mixing 70% E85 with E10 in his gas tankEcoBrick Bob said:In running around 70% Methanol and with my KB Boost-A-Pump with Torrie's modded tunes and 93 E-10, I saw FRP drop as low as 850. We backed off some and attempted to keep FRP above 1,200 psi and Lambda no higher than .82 on both banks. I'm sure that if I had been running 100% methanol that I would have been able to get more out of my Flex with the same goals above, but at 70%, we had maxed the fuel capabilities of my system in Torrie's opinion. Generally, it appears to me that a Flex is about .5 seconds slower than a SHO with the same mods.
