Once I get fuel pump internals in my Mazda speed3 I'll be running a 33% e85 mix and hoping to break 300whp with this shitty k04.

There's someone in the forum that's running 59% e85 with basically an intake, test pipe, fuel pump internals, uograded top mount intercooler, and Cobb access port and tuned by himself. And he's just shy of 300whp.


E85 USA great power added with a boosted car.

Yea as you can see from my posts back in 07 I started with a low mix of E85 and slowly stepped up. I found on my Accessport Stage 2 tune I was running at the time 34% was my sweet spot. But id start at 25% then slowly work your way up to be safe. But definitely get a fuel pump, because as I found in those reports back in 07 stock pumps die up in the higher pressures on boosted cars (common knowledge) and on E85 thats real bad. If I were you Rich id pick up one of these new 340 pumps from areomotive, they are made for E85 and have killer flow. If those were out back when I got my 255HP wally I would have gone for them. And buy them from Justin (AKA JayJay, AKA the guy who runs this site, AKA Tunersports). http://www.clubintegra.com/store/aeromotive-340-stealth-fuel-pump_mp664.html

My intake pump flows 220lph. I need fuel pump internals for my CDFP (cam driven fuel pump) my fuel flows at 1700+ PSI and once you start doing a FMIC, or down pipe the pressure randomly drops to 900psi. Which is lethal. There's a few people making over 500whp uncorrected with stock pump in the tank. The CDFP is very weak, but with upgraded internals you can make 500+ whp, but the injectors are are 98% duty cycle, and there's no aftermarket injectors for us yet. The one person who's over 500whp is still on stock block! Also, there's no aftermarket cams/valvetrain for our platform either. So in a year or two when there's injectors and cams, I see 700whp very achievable. And nearly 600whp on stock block.


Not bad for a $24k car brand new, with 5k in mods!

The electrical conductivity issue is not significant in the case of ethanol. It is detectable with a dialectic constant tester. It DOES become a significant issue with methanol blends which is why methanol blended fuel is so aggressively corrosive. The main issue with methanol is it aggressively attacks certain metals like magnesium and zinc. One of the reasons everyone is looking at ethanol is the 30+ years of successful use of high ethanol fuel blends in Brazil and low ethanol blends here in the U.S. with essentially zero problems after they changed fuel line and O ring and seal materials in the fuel system. - stream videos via tubemate apk
