Will I have enough fuel??

[Ben]

Cliff notes: Is a rewired evo IX (about 190 lph) fuel pump enough for 400 AWHP???

Ok, throughout this, if I have something that will limit me from reaching my goal, let me know!!!

My profile mods are up to date.

Things on the way:

Jacks Transmission value build with evo III 1st gear and double syncro 3rd added
arp head studs

And as soon as PTE releases it
an internally gated PTE SCM6152e
They said they are making some updates, and will be releasing it in 1-3 weeks. This was last week.
I will also get a more aggresive chip from keydiver. Mine now is for 91 oct, and a target afr of 10.7

Will I have enough fuel for 400 AWHP, and what should I set my base fuel pressure to???
I can get a 255 walbro easy enough, but I'd like to not mess with it if possible.

IMHO you need a 255 and AFPR. SBR FMIC is bad ass! get it! I used a felt gasket on 20ish psi on a small 16g with no issues.

The AFPR kit is on it's way here.

everything looks like a good set up you might be close to maxing out the 2g maf you might want too look at mabe a gm for more flow. As for the fuel pressure between 42 and 45 should work good with your setup. vary vice setup setup thou let us know how it does when your done

Somethings I forgot that are kind of important. oops
I'm running 93 oct with nos brand oct booster. It's on of the brands that is supposed to raise the oct level 60 points, not just 6 like most. (I did some searching here on oct booster and found some cool stuff). I didn't know if the stuff worked, so I tried it and watched my logger. I was limited to about 14-15 psi with this 16g w/o the oct booster. Using the oct booster, I run 22 psi in 4th and 5th with little to no knock for the 1st pass. stupid stock smic!!!

I'm thinking of dropping the oct booster and getting a meth kit after I get the turbo.

And I'm wanting to run at least 22 psi. maybe 22-25 psi, I'll just have to see what my injector duty cycles are and how much timing I'm able to get w/o knocking.

 

[leathaltsi]

realy octain booster helped that much I thought all that stuff was garbage. there is a gas station around here that sells turbo blue 110 and 120 octane but I havent tryed it yet its like 7 and 9 bucks a gallon

 

[Ben]

If you search on here, you'll find that most brands of oct booster only raise the oct 6 point. 10 points to one level of oct, so you just went from 93 to 93.6. NOS brand, and torco, and I think I read there's another one, all raise it 60 point, so from 93 to 99. I don't know weather it gets it that high, but I know I can run way more boost with it.

It is 100% impossible to have the lil bottle raise the octane of fuel by 60 full points.. The only way it could do that is if you mixed a whole bottle of octane booster in with a cap full of 91 octane.. It does help, though.. Alot of people put it in their car without understanding how an engine works and understanding the concepts of octane and knock..

If you do a lil research, you can actually learn how to mix your own octane blend of race gas.. Its very simple.. We do it for a friends IROC all the time.. 1 gallon 91, 2 gallons xylene (I think, I cant remember what its actually called.. His dad got it from his work), and a cap full or 2 of automatic tranny fluid or marvel mystery fluid... We can run a STUPID amount of ignition advance with the supercharger, and get no knock whatsoever.. Its always worth looking at.. You could run 93 in the street at "x" psi, then put the race gas in for the weekend or race day or what ever.. And if you use it alot, then you would be good to just get a drum, and mix up your gas before you go out that day.. It sounds like a lot of work, but its really not.. And its better to get pulled over and have a cop see NOTHING than to see you doing water/meth injection, which is illegal as f**k on the street..

As has been mentioned I have used the NOS brand off road octane booster & have noticed a descent amount of knock reduction. Without it I could run around 22 psi & with a full bottle added to around 1/3rd tank of gas I can bump the boost up to 26 & run a couple more degrees of timing with no knock. Now at ~$15 a bottle CDN, this defently isn't the cheepest route to go, but it works great at the track to run pump. If you need this kind of knock reduction on a daily basis, meth injection is defently the way to go. There are more then a few locals that run 30+ psi on pump with meth injection.

Thats a stock Mitsu composite gaskets your running? If so, I wouldn't worry about for your goals. A stock gasket & ARP's can go a long way (obviously with a descent tune). I've run mine to 26psi, no issues & know of others who have run 30 & even abit more with this setup.

And its better to get pulled over and have a cop see NOTHING than to see you doing water/meth injection, which is illegal as f**k on the street

Is this a law thats just specific to Cali? I know here water/meth injection isn't illegal & you can be pretty stealthy with the install, you would have to examine my engine bay pretty throughly to try & find any traces of the meth kit.

 

[Ben]

Yeah, I never said that I know it raises it that high, I just know I can run more boost w/o knock. I went into it knowing it wasn't going to get that high.
I HAVE to have something to run all the time since my head is milled. Or I could retard my timing, but I can only run about 14 psi on a 14b w/o a bunch of knock. That's also with about 19 deg of timing up top. I'm still running the same timing, but at 22 psi in 4th and 5th. It's about 19 psi in 2nd and 3rd. That's with the oct booster.

I think I'm just going to go with a meth kit after I get this turbo on and running.

Will my rewired 190 be enough, and if not, how will I know?? start running lean? fuel cut?

I think I'm going to try 43 psi base fuel pressure 1st and then see where my IDCs are.

My target afr right now is 10.7. what should I have jeff at keydiver set it to with this set up??
11.1-11.2?? I don't know much about this yet.

If you up the base fuel pressure on your 1g from 37 psi you need to compensate for that. I'd also recommend something other then the chip for fine tuning. Like an SAFC or something along those lines. So what turbo are you going to be running to try and make 400awhp? The scm6152e will do that with no to much tuning, I've owned 2 of those. If your trying to do it on a 14b forget it, and on an EVO III 16g it's a bit of work with some race fuel or e85.

 

[Ben]

I'm compensating with the chip. I'll get a reburn. I'm going to see what the chip only does for me.
And yes, I'm going to go for the 400 AWHP with the 6152.

 

[leathaltsi]

If you get your chip from dsmchips. They will compensate for fuel pressure. Just let them know what you are running at the time of your order, and they will burn it for you

 

[blownturbotsi]

You'll be able to reach that on low boost.
