HP HEAVEN - exp with modding our engine

i think the pod filter they are talking about is just a universal 3" inlet cone style filter. the benefits are a much less restricted intake, the downside is a pretty significant heat gain, you could remedy that by putting in a heat shield of some kind but im pretty sure that would need to be fabbed on your own

It can be done with some serious surgery to the stock air box...

Thanks Man...it ain't exactly pretty, & has a few rough edges here & there, but in side by side testing with Kenny's VX on the same stretch of road, at the same time, my intake air temp was about six degrees cooler due to all the insulation I've done on the inside of the box & also the inner walls of the c/f intake toob.

[LittleBeast]

Yeah mine is the Morgan Tech with absolutely NO heat shielding at all!!!!! I need to fix something up, thanks for reminding me of another thing I need to do. Maybe I can do that when I finally install those shiny new red radiator hoses Seriously though you have given me some great ideas of how to pull this off, what heat shielding material did you use?

That green stuff you see on the rear edge of the box is 1/4", foil faced styrofoam commonly used behind steel siding. I cut pieces to fit wherever I could & glued them in place with silicone.
I packed plain old fiberglass insulation between the inner (straight through aluminium) & the outer (c/f) walls of the intake tube.
I saw a pretty slick heat shield/air box made from a rubbermaid wastebasket, I think it was Hotsauce?

[Ldub]

My mistake, it was Hotsauce, but it was a yellow gas or kerosene can, not a wastebasket... check his gallery.

I do not think they know much about this engine at all. They talk about the # 6 rod bearing being the bearing that fails ,when it is the #1 rod bearing.Also in my opinion it is due to lack of oil not lack of pressure. The oil system in our engine feeds the front of the motor first if I remember correctly. shawn

[JHarris1385]

If it feeds the front first would it not be the first to be filled and back to be left possibly dry?

It states the lack of oil pressure is the reasoning for the oil or burning thereof.

anyone looked into this yet?

Does anyone know which Pacemaker headers he is referring to, or which would fit the VX? The Pacemaker catalog doesn't seem to mention anything for Isuzu, Acura, or Honda. Or do you need to have these custom made?

Naaaa...me be think'n I posted a reply in a link I was on, when I got side tracked...

for the hedz up...

I agree but for other reasons. As someone who's spent too much time in a performance forum (for Corvettes), the "canned" answer sent to JHarris (the OP) was a bit to contrived.

Typically, modern engines have more than adequate supply for intake air. Making it colder won't hurt MPG and it might help a bit. It might help with power too...but only VERY slightly. Again, it's due to well-designed factory systems.

The ECM is the same issue. Factories want to get the best out of factory performance and any limitation will come from intake, heads, cam, headers, and exhaust. It's the mechanical configuration of an engine that will make/break it. Because of the ODB2 system and intake config, you see a 4k pound vehicle doing pretty well in terms of speed/performance. I think MPG could be a bit better -- but that's because ISUZU was looking for a flagship performer -- not necessarily a fuel sipper. If I got into the tuning parameters of this motor, I'd double-check the PE (performance enhancement) parameters to make sure it didn't hit power AFR sooner than "normal". Maybe another thing or two as well.

For the size motor (3.5L), a 2" exhaust isn't out of the question. Going bigger (and especially too big) will hurt off-idle and low-end performance. Not something you want to do to a street engine or one doing off-road duty. This is the kind of stuff you do for a 1/4m race car. And, the VX wasn't designed for that. If that's what you want to make it, you'll need to shoehorn a V8 along with that "Wolf" ECM.

Cats (since early 1990's) have gotten way less restrive. Plus, everyone has tried the gammit of mufflers. Short of doing this 2.5" exhaust and trying to get to 100mph faster, I think the OEM exhaust isn't setup that bad. I'd like it better if the PS didn't wrap over to the DS -- into a single outlet -- but that can be altered easy enough. There are a couple of nice dual exhaust systems on this board to emulate.

For real performance, ported heads, a cam, headers and retuning would be the ticket. I'm not seeing enough interest (in this forum) for that sort of thing. Considering the stock compression ratio is low enough, I think super- or turbo-charging is the way to go. Looks like a few have gone that route too!

I love the roots-style SCs I've seen. I think it would be cool to have one!

:cheers!:

So wouldn't replacing the stock oil pump with a high flow version fix this issue? I think there are other factors at play here.
