I would never call you cheap, all I'm saying is that you know well how our's cars are runnig, and you know that in the states a lot of people doubt what we have accomplished. we do set high standars on VQ 35 engines and still when we post our results some people think we are bull sh ing. remember that on the forums there are a lot of people that really dont know what they are talking about.

As I was talking to carlitos we do laugh when others need to spend so much money to be were we have been for the past two years.

I know there are a few tuners on this forum that know their stuff but I would dare to challange a lot of them to show as many cars as we have that could outperform our cars.
my peace

 

No, becuase it doesnt address the in tank FPR. So you have two regs fighting for control...both bleeding off pressure at opposite ends of your fuel system.

 

I know buddy, I know, I'm with you 100%... for example, on this thread some people call my whp a "little to high" for my set up, hehehe... but everybody learn sometihng everyday

 

what in tank fpr? It has a walboro 255 pump. I bought the car this way and am just trying to figure out everything.

 

please post some videos of the supra, so that people are able to see what a daily driven automatic supra can do, also see if you have a couple of video of our cars at the track

 

I post it on the first page

 

Kike "webcarconnection", go safe and install the return fuel line that way when you boost up one side of the injector you also boost up your fuel psi on the other side for a safer and more stable tune (1/1).

I still have my CJ return correction kit that I use to have before the twin pump setup, give me a call and you could have it.

BTW carlosg, know I have 749whp, it must be a generous dyno, jaja!! however 7 broken axles to include a set of DSS level 5 and two tranys tell a different story

 

Breaking parts means ****, I have seen NA cars break axles it is just called not knowing how to launch and also breaking trannies means not knowing how to shift.

 

Merlin it sounds like you have a aps fuel set up. Is the regulator a large gold housing. If it is it should be good to approximately 500 rwhp. Sharif, does the aps set up has 2 regulators on the assembly? Are you sure about this?

 

no it's red and blue, it's a nice aeromotice regulator with a liquid filled marshall or something gauge.

 

Wepa... Thanks for the offer, I call you later

 

I have a question but I don't want to start a debate or something... Can you share your expirience with cars that you guys tune w/o the system? What type of tune do you guys use and how much WHP are you guys putting with this set up?

just to know more about it... Thanks!

 

Hey! westpak i have another G down here in P.R ,but i think that i used another "generous dyno" because i put down 613 whp on mix c-16/ 93oct and 670 with 75 shot. I must be generous right?

 

With the exception of about 2 or 3, no cars we build, TT, and tune run a fuel return system. We have built car after car (Z after Z, G after G, etc) that range from 400whp to over 800whp and all are running strong. The tunes vary depending on the customers goals/needs/budget. Some are full race, high boosted, race fuel only beasts, and some are moderately boosted 91 octane, daily drives.

 

The APS uses an in tank FPR plug, so it addresses that piece as well. Then it has a rising rate FPR that mounts on top of the fuel tank...behind your rear passenger seat. APS addressed all the issues.

 

Gerardo now I'm scared cuz I'll be going to a generous dyno and wont be knowing my real whp, maybe if I substract let say 200 whp to what it shows then it would be real in other peoples real world

 

Thanks for the reply, so you tune for 600 whp with what? E-manege or Utech or Fcon and 650 or 750 injectors w/o anything else for fuel?

 

shariff so is my setup ok to use? should I just pm you directly?

 

some good reads regarding returnless vs return fuel system:

(sort of how the APS return fuel system works)
http://autospeed.drive.com.au/cms/A_2637/article.html

needless to say... although a competent tuner CAN make a returnless fuel system work, the conventional return fuel system's function and design seems more feasible and proper for boost/pressure regulated engines. a lot of FI guys have return fuel systems because they do their job efficiently.

 

I beleive you and I hope to give this a whirl with my boost up. I would imagine that to offset the loss in fuel pressure at the injector nozzle due to the increased manifold pressure you need to run larger injectors and/or use larger duty cycles than a return system would. The pressure differential between the fuel system and boost pressure should remain constant so the tune should hold as long as the fuel pump, fuel feed line diameter and rail size are up to the task.
