Santa Came Early For Me This Year

:
2006 Mazdaspeed 6
Just thought I would share with you guys that there will be another built speed6 with a gt30 hitting the streets in less than a month. My current mods are CPE CAI, CPE TBE, CPE engine mount, CPE FMIC, CPE EMS, CPE battery kit, EIBACH pro kit lowering springs, TWM short throw with a desert eagle shift knob and other interior accessories. What I just bought is a brand new shortblock with ARIAS pistons and PAUTER rods, ARP head studs, SPEC stage 2+ clutch, ATP gt3071 turbo kit, and alot of tuning time. Any recommendations or additional info on the secondary cam driven fuel pump upgrade I've been hearing about would be greatly appreciated because i'll pick one of those up as well. The goal is very low 12's, perhaps even 11's if I decide to get some minor head work done.

Wow, I am almost as excited as you are about it, keep us posted on how it all works out, I love seeing Big numbers and quick quarters out of speed 6s
 
looks like you went with the exact setup as me except i think u should have went with the 3076r. You will be disapointed when you have a motor that can handle 500+whp easily and a turbo that cant push over 400whp.

Call Garrett. The 3071 will easily push over 400hp. Especially when the fuel pump upgrade is complete, tested, and verified. You also have to remember we don't have a broad rev range, so we need to get into boost as fast as possible and we are also working against an evil throttle plate who likes to call it quits far too soon.

I recognize that engine! be good to it and without that pump I don't think it will hit the 400whp mark safely. you basically have what our car has and yes you can crank up the boost more now but you don't have the fuel to go with it.
 
Yeah, but what happens when you're tuning for 430s on the dyno and the upgraded cam driven fuel pump gets starved by the in-tank fuel pump? Hopefully fuel cut, cause detonation on a built motor will destroy your head and some valves for sure as well as whatever cylinder(s) pop. How extensively have you guys tested that fuel pump limited to the flowrate and pressure of the stock in-tank fuel pump? I believe we have hard fuel lines for the most part, so we don't have to worry about fluxuating pressure too much. But I'm worried that the stock in-tank pump will not be able to deliver enough fuel to the cam-driven fuel pump to create the big numbers people are starting to go for. Sure the upgraded cam pump will be able to flow enough, but what if it's not getting enough to push through? Are the standback and the cam pump going to prevent the ECU from hitting fuel cut? That would deffinately not be a good thing.
 
the pump in the tank is just there to get fuel to the cam pump that's all it does so I'm sure it will be enough because all we are doing is upping the pressure.

and if need be we can put in new intank pumps...
 
What ATE is saying is, when upgrading the fuel system, start from the beginning: The fuel tank (in-tank pump).

If we are still seeing a lack of fuel, upgrade the cam-pump.

Theory is, upgrading the fuel system will aid in the TP closure issues around 5500rpm.. but nobody has yet to confirm this except for one or two people who don't bother going in depth or proving it.

i will get the pump when you guys say the word that it's ok to buy, after you test it and all.
 
sexy...I almost traded my car in on a MS6 the other day...then I realized the reality of being a broke @$$ college student.

And the rest of the car that can barely handle the 274 hp Mazda gave it.:eek:
