I think a mod should merge these threads (please), there are like 3 that have morphed into the same subject!
Umm, what can I say... The standard HO manifold would mean you're not getting anything out of your GT40Ps or much out of your exhaust. My EB will probably be able to keep up with your ED (despite E7 heads) because your HO simply isn't allowing your GT40Ps for flow to their full potential. If you're keen and take pull your t/b away from your HO, you can measure the internal diameter of it. The HO has like a 55mm ID. I have a 65mm t/b mated to my 55mm HO, so I don't get the full potential of the t/b. I do however get greater responsiveness due to the butterfly opening/closing just as quickly as the standard t/b, but it allows more flow due to having a larger ID.
I'll post up a pic showing the differences between the standard MAF and a 70mm one (my old & new ones)
Maybe posting in the Windsor section (or maybe a mod can merge these threads & move the single uber thread to the Windsor section
) will get you more attention for your questions. Coz not all the Windsor guys look in the E-series section, especially since the vast majority of E-series owners have I6s.
If you make a new thread in the Windsor section, do 3 things:
1) State what you know your ED has
2) state what you want to have done to your ED (and ask how to go about doing this)
3) make links to your other threads, and ask mods to possibly merge your threads to make life easier for everyone on the forums
Despite my advice to make another thread: Don't get all thread happy though!
One last bit of contradicting advice: maybe posting in the Superchargers/Turbos/NOS section???
