    Sheet metal intake in the works?
    It prolly boils off somewhat but gets recharged so to speak when it's time for that set of valves to open and gets a fresh shot. If there is any heated fuel left, I would imagine that this would possibly make the "fresh" shot more explosive, and possible where some of the engines HO power came from. 200-210hp, for the Multi Porters, and only a small gain from the sequential injection to about 215hp, with slightly better flowing heads. Although when compairing the two different heads (older to newer) I could'nt really see a difference. Both sets have massive intake ports. But the newer LQ1's (TDC) had a better larger port primary (lower) intake. But the gasket area of these is a poor (thin walls) design, and notorious for leaking top and bottom. The older ones though they have smaller openings on top had more gasket area which made for a better seal IMHO.

    I dunno maybe custom steel or aluminum intake. Still on the drawing board, as to flow and injector placement. I'd like to utillize the three shot for each open set of valves though rather than the pooling effect it had..

Later years had sequential injection and eliminated the "all @ once" injector firing. The plan for me now is to move the injectors out of their ports and fire 3 when one set of valves is open rather than letting it pool on the valves that are closed.

    With no after market intakes made guess who has to make a custom intake too wink wink..
    Advantage 94+ cars Sequential from the factory for the higher power numbers

    Yeah 5 more than the old 5spd and 15 more than the old auto's = not much lol, also the rev limiters on the 94+ cars is almost 1000 rpms lower..

    Me too but it has to be happening between gears rather then durring a pull and they were also limited to 110 top speed.. Been past 125 a handfull of times in the 92, bounced the needle off the bottom a few with the chip, comp, cai, and exhaust too.

    An old buddy of mine had a 98 (ish) grand am gt tdc stupid thing was set to shift @ like 6200. Which comming out of first hitting second was far to early @ 4200 ish which is just a hair outside the sweet spot in the tdc, so it would lay down for a sec then come alive again.

    Picked up a set of EFI and Tuning books last week -- one chapter talks about batch injection and gives a pretty good description of how the system works and what happens to the fuel between intake events. You get that thing done and I may have to take a ride south to check it out.
