Next step/help in 1000 rwhp build?
Next step/help in 1000 rwhp build? Right now my car is sitting at 850 rwhp at 16 psi. I want to push it to 1000 rwhp with this single turbo set up. I will try and list everything I have on the car that is relevant to what I am asking. This is on 93 octane and 100% Meth.
LME forged 408 with 9.5 to 10 compression
LJMS cam
Tea CNCed TFS 245s
Huron Speed V1 A/C kit
BW T4 S480 96mm turbine, 1.25 exhaust
80lb Deka injectors
dual Walboro 340s
Alky Control Meth kit, running dual nozzles
This is through a T56. I want to get to the magical 1000 rwhp mark. My tuner said I really need to up my injector size, which I agree with and understand, and that I need to run more octane. Is this all I can do or are there any other things I can do to get to my goal?

People have made 1000+ with Deka 80s through an auto.
What does your duty cycle look like now?
Bigger injectors will let you keep fuel pressure down and your pumps happy.
Your setup looks 1000 HP, why not slowly increase boost and see what happens with fuel?

race gas and turn it up!
Duty cycle was 80% according to my tuner. He said to get some ID1000s and run some race gas and he would retune it. I was hoping to do it on pump fuel but I guess I can't?

More boost, more meth, whatever.
1000 isnt difficult on almost any fuel if the combo is right. Although if you had only pump fuel in mind, opting for a little lower CR always give you a bigger safety margin and more room for boost !

Your tuner must have timing super conservative. My 370 with stock 317 heads makes 830 rwhp through a th400 on 15 psi with a little 76mm turbo. If you just want a 1000 hp dyno sheet be safe and throw in some race gas. Your 80s with meth and race gas will do 1000 I'm pretty sure especially through a t56. Sure you could try and do it on just pump and meth but if your tuner isn't comfortable pushing it that hard a bit of race gas for safety is a no brainer.

Well, it sounds like the only thing you need to hit 1000 RWHP is bigger injectors, if your tuner is letting that be the limiting factor. Or a different tuner that will push the limits a little more, if that's what your looking for.
Not really directly related to the 1000whp goal, but you live in Memphis, you have E85 available, honestly I'd go that route. You'll need injectors like some 160s and enough pump, but it is way safer. You won't have to worry about sourcing meth, or a system malfunction. Dual 340s should get you to 1000 thru a T56, if you have decent fuel lines, but that would be about the limit. With 160s, you could also drop the base pressure to about 45 psi to help out your pumps too. I was reluctant to make the switch to E85 over sourcing concerns, and just that it was different. You hear stories of it absorbing moisture etc. Well so far, I'd consider it the second best thing I ever did with my car, right behind replacing the stock torque converter. I wish I'd done it sooner.

I want to go E85 and was actually thinking of going up to my tuners shop and talking with him about it but it isn't readily available in Memphis yet. There are a couple of places that have it but it is a one hour drive from my house. I was thinking of buying a 20 gallon can and just taking my Honda Civic to get the gas when needed.

You are more than fine to go past 80% DC on the injectors. If your car hits target afr during WOT, then what is the problem? I was at 931whp thru a th400 with my s480 cast setup. 21psi. I think that was around 88% DC on VP110 leaded.

With most modern stuff.....really not a problem at all.
This was my thinking as well, as long as the afr is where it needs to be why does it matter. I am no tuner though so I just let it be.
