Hey guys, im going to run the 2.87, and make some good use out of this fuel system
Anyhow, ive been wondering what I can add to make this setup as safe as possible to have the motor last atleast a year.
I was thinking of the following but dont know much about them:

~Fill up with 1 gallon of race gas and the rest 91, (maybe buy a drum)
~Intercooler sprayer, water or nos
what else?

Im not looking to spend more than a few hundred, I could probably get a 50 gallon drum of 109 for 300 bux...

 

OK I bit, stupid question; or maybe not. WTF is the 2.87?

 

Adding one gallon to a full tank of gas , isnt going to change the octane rating enough to do any good . You would need more than one gallon . A good tuner would be the place I would be spending that money on

 

2.87 pulley for the vortech supercharger

 

what booger said. get the car re-tuned by a competent tuner. honestly I don't sede why more of the vortech owners have not gone down this route instead of the 3.12. the 3.12 adds only 1-2 more psi compared to the 3.12. If the ST and TT guys are pushing 450whp on the stock block I don't see why the s/c guys can't do it especially since they put out less tq. Go for it!

 

jorge, i dont really think its from being cautious with the motor, i think it has more to do with overspinning the blower.

 

yeah, that and using it voids the blower warrenty completely

the 3.12 at least just takes the warrenty down from 3 years to 1 year.

probably isn't a bad idea to start with at least the 3.12 pulley for the sake of if something were to go wrong with the 2.87 you'd be SOL where the 3.12 you could at least send in the blower to be fixed.

keep in mind that 440whp is probably about more like 480whp on a turbo as far as the engine stress due to the parasitic losses, but in the case of the vortech, the tq is much lower so in some ways the engine isn't working as hard as on a turbo car - partly why turbos make so much more heat than superchargers

 

Im taking it to technosquare, so the tuner part is covered After technosquare, should I take it somewhere else to get it dynotuned?
Im more concerned with timing that afr, so I never really considered dynotuning, because I trust TS with that part fully.

Has anyone seen any other good products to use?

 

Flashing for the timing works . But using a flash for the fuel tuning doesnt work past 6 or 7psi . If thats the way you want to go . Have them flash for timing only and use the SS Box to tune the fuel

 

Walbro 255 and 380 injectors should give you enough to tune the MAF signal.

 

The 2.87 pulley will get him around 12psi of boost and I dont think the 380's will be enough . TurboN is using a flash [timing and fuel ] for the systems and I just read a thread that Mia said they are able to flash for around 8- 9psi . But anything over that you will go lean . I just wouldnt trust tuning fuel with the MAF and higher boost levels

 

Ahh that would explain why I know jack about it. See Sig.

 

So are we basically saying that running the 2.87 pulley will:

1) void the Vortech blower warranty altogether?
2) require the use of probably at a minimum, a set of 440cc injectors?
3) require possibly a Walbro 255lph fuel pump?
4) be safe to run with proper tuning on stock internals?
5) be able to be tuned with the SS box that comes with the Vortech SC?

Am I correct in my understanding of the above?? I have considered going this route, but am scared of blowing the motor.

 

I already have the 440 injectors, walbro, and aam fuel system. I spoke with Tadashi, (I think) at Technosquare, and he feels that he can tune the car, but he was not so sure the motor could handle it. I told him how much power the AAM car just made with the 2.87 and he was surprised it was a stock block.

Anyhow, does Technosquare have limitations? I am having them drive the car and tune it, so its not like im just sending in my ecu. The only thing I can think of besides that would be something like Greddy emanage and dyno tune.

I know there are a few members on this board with the 2.87 and stock vortech fuel system and a tuned ss box.

Yes the warranty will be void or reduced to 1 year....I know its reduced to one year with the 3.12...dont know on the 2.87 ...but Vortech wouldnt know what pulley you have on....they would only know that you changed pulleys , because the paint they put on the bolt...sorta like a seal

There are several way to address fuel.....I know the stock Vortech system has handled the 12.87 so far on several cars . Going to 440's and the walbro , with the stock fuel rails and returnless system probably would be the next best step....I dont know anyone running it like that personally . Going to a full return system and bigger injector...as you know ..would be the best way

The Jury is still out on how much the stock block can handle for long periods of time....Adding F/I is going to lessen the time no matter what

The SS box is more than cappable of tuning the Vortech . I still have it , the JWT TT kit , Stillen , And one other TT kit uses it .

 

This is how I ran the Vortech, but I was using the blue Emanage. I am sure it wouldn't be any different with the SS box.

 

Here is a grocery list of what I am kind of looking at:

-RC 440s for $498 shipped from Hopup Racing
-Walbro 255Lph pump for $109 shipped from Hopup Racing
-2.87 pulley & belt for around $125(?)
-Retune from CP Racing for $200

Would it be safe to run this? What boost level is this pulley good for? I think I am seeing around 8-10 psi now on the 3.12 pulley.

BTW, what is the advantage of having the return fuel system?

 

Steady consistent fuel pressure.
