I make 13psi now on the 3.00", I expect 15, maybe 16psi on this pulley. Will probably order a 3.70" Griptec as well to see if I can get 16psi out of the set up
And yes, stock engine, stock trans
You're literally pointing at the third spot that goes to the HPFP. Remove the stock hose off the HPFP, put the T block on it and you are done with that part.
The 2 small black wires are your fuel level wires, you have to cut the stock wires off the stock plug and connect them to those 2...
Stock they do make about 11psi, least that's what they make here in Texas. Also, the Roush has a actual MAP sensor in the lower manifold, so it does know the actual manifold pressure, it's not inferred like it is on non-18+ Roush cars
So I ended up ordering the aux idler for my Edelbrock. The guy who has one now has been able to get 17psi out of the 2.75" pulley with Lund tuning it. They told him it doesn't look like he has any belt slip, this was on the normal Edelbrock 2.75 too, not the griptec version.
It made 16psi on...
Seth in the Edelbrock Facebook group is working on a aux idler kit for the 6 rib, adds more wrap and should let us run 69mm(2.75" pulleys w/o slip). Thats just a mock up piece he made to get the spacing right, said he will test it out once he make a aluminum version
This pic here shows the...
I make 13psi on a 3.00" Griptec with LTH headers, since you have stock headers, you might see 14-15psi though....I dont recommend it. When we pulled my stock headers out, both cats already had cracks in them and I was only boosted for a few months when they came out
Fuel that has entered the return line cannot make its way back into the feed. Fuel will take the path of least resistance and that is the return line bc it has very low pressure in it compared to the feed line. Teflon tape should never be used on AN fittings, the only thin that used teflon in a...
If you are using a single regulator set up you need to bump up your base pressure and not run vacuum/boost reference. Tell your tuner to send you a static fuel pressure tune, I personally run mine at 62psi and it will hover +/-2psi most of the time.
If you want to keep the reference, I'd...
tenability is not an issue if you are using a known TB like a VMP/VMP, how ever if you are not seeing a pressure drop with the 103mm you are more than likely not going to see any gains. Larger TBs help alleviate pressure drop, if you have minimal to do drop, then going bigger will not yield any...
This is outdated info, you can drag the HPFP below 58psi just fine, I myself how ever run a static 62psi, that gives me a delta pressure of 49psi, which is more than enough for my injectors, they're barely at 45% IDC.
I do plan to switch to vacuum/boost reference though, will prob run 60psi...
I run a single regulator kit on mine, takes up less space in the engine bay, running about 13psi and it's given me no trouble at all. This is with dual F90000274 in the tank
It works like it does any other fuel system, you can run the rails in series or parallel, in series you run the feed through bank 1, then across to bank 2, finally to the FPR where you return excess fuel to the tank. The DI is fed off the same hose that is connected to bank 1 rail.
Parallel...
No, dual regulators are not needed for any power level you may run on a gen 3. The dual regulators strategy came out back when the engine first came out and tuners did not know how it would all work(FORE still has this warning on their site).
The concern was that you could not drop the...
