3.0L AWD 5-speed minivan!

[RoadWarrior222]

I phoned Monday and my cam is MIA The guy I was in contact with quit so I'm pulling my hair out to figure out what's going on. I *was* planning to pick up the heads and the cam at the same time but now I have to put things off again. I've been WAY to busy to work on the van anyways, but still

Bummer, hope that gets straightened out.

What was the guy's name though? Maybe he lost a pair of mine and a pair for Adam and Brent too...

[Vigo]

Bwahahaha i like that thinking..

[moparman76_69]

Out of curiosity what ratio is your transmission?

The guys name was Matt. When I was talking with Dave Crower last week it sounds like his leaving was not a "clean" break.

It's a 3.77 ratio transmision.

[Reaper1]

Nice heads! Sucks about the cams though....

[Kreel]

It took a week but the cams have been found! They're supposed to be done and shipped out by the end of the week

Fuh, I really wanted my name on that list at your expense. I want more info on how everything fits but like you, I have no time to apply anything to my fun car at this point. I really want lsx springs but I don't have those valves, and I don't think want a set of those valves since the machine costs are so high that a little more money can bring in custom valves that can deal with more heat if I ever rock the house (probably never).
Interested in how your cam feels when you drive.

What is your installed spring pressure right now? Install height? retainers? Normal Ls1 locks?

BTW, you ever consider a reverse hybrid trans? I think your heavy van would be perfect for a 1991 era short gear with 3.85 final drive.
I would be interested in the same thing if I really got deep into drag racing this car and trying to maximize performance in the 1320. My 4th gear is going to go WAY too far when I up the rev limiter again. Hope you guys realize that a 3.0 at its real rev potentials will never top out 4th at the track...and hopefully never on the freeway.

You have currently working AWD? I thought to get the AWD to work you had to use a 3.50.

[Vigo]

The awd system on the van is sort of weird. If you take the gear ratio of the transfer case and multiply it by the gear ratio of the rear differential, the result is a 1:1 ratio. So, whatever the input to the transfer case is (3.77 trans), the AWD setup will just replicate that at the rear wheels.

[moparman76_69]

thas how i was thinking it worked but after talking to someone at sdac he stated the overunning clutch would operate correctly that way so i was going to pull everlthing apart to verify what was what, i still might do it and start an info thread so we dont clutter up awd build threads with this stuff

It certainly has been the most expensive part of my project, but not too bad for price I think of these heads as a stepping stone towards all-out custom valved heads. I didn't want to drop the $$$ for custom if something in my setup doesn't work out. I think if Crower gets the cam right (I told them *many* times about the base circle issue) then everything should just fall into place Oh, and these heads WILL rev. My power should be dropping off around 7-7.5k but I suspect the heads could take 8k all day long. This is all hopes and dreams right now but I will make that a reality.

Can't recall the details off the top of my head but It's around the 120# range, 1.75ish install height with LS1 locks.

I'm waiting for the day my brother gives up on his spirit r/t to get my 3.85 final drive

Well there have to be people smoking the hybrid trans crack pipe who are throwing those things away without ever doing a gearing calculation to figure out what kind of gearing would actually make them go faster....

That kinda makes me unhappy that you got your install height so high but Ed was saying with OEM height valves its only 1.57" That means you can fit some crazy lift in there!
Permission to hate? Hate hate hate. Now I am gonna get real jealous when things don't work out for me the way I want. Did your stems get undercut? Head shop back in Utah was saying he could undercut OEM valve stems for the TIII valves when I was working on a project for Bansheenut. Later I ended up not wanting to do that because TIII valves are microscopic for their displacement and it would be polishing a turd. Wonder if Ed could get any gains with an undercut OEM 3.0 valve. Glad you are doing the testing

Have you guys figured out if there is a cam lift/overlap point where the valves will hit?

Guessing your blower will run out of steam before anything else. If you start liking this setup, you might really like the step up up to a screw blower and crazy efficiency. My friend did his own blow through water to air intercooler for his 1uz v8 toyota 4 runner build. Thats another fun thing to consider. He was using an m112 blower because at 4400 feet the m90 could only create about 3 pounds of boost on 4.0 v8.

Craziness! I'd love a 3.85 ratio in my van. It'll help getting 4000 lbs of steel moving too

So my install height is actually higher on the intake then the exhaust because of a difference between the G54B valves. I can't recall at what point (ie. before/after LS1 locks) but intake could potentially lift to 0.500"+ and exhaust 0.480". If everthing works out as expected then using custom valves you could push the install height even higher and see 0.600"+ lift. AFAIK nothing was done to the stems.

Max lift during overlap while still maintaining some space between the valves is 0.100". Now this won't be much of an issue for me since I don't want a lot of overlap in my cam to begin with. Where it *could* be an issue would be some all-out NA with a ton of overlap rev'ing to 10k...

I'm already planning for a m112 hybrid. Not sure if I'll do AWIC or the hybrid first But...I have a long ways to go before I consider either of those options

[Ondonti]

That hybrid seems kinda pricy. 200% more and get the screw blower lol. I wish the price was lower on those.

[turbovanman²]

Are you going to run the new combo n/a or do it all at once?

[Kreel]

Maybe...I honestly haven't looked into screw blowers. All I know is $$$

Are you going to run the new combo n/a or do it all at once?

The original plan was to run n/a (with new setup), then supercharged. With it already being July I might have to change things...stay tuned.

[Ondonti]

If you could swing it, you might love it. 2k in the hole over the cost of what you are talking about, but a fraction of the drive losses and more efficient then most turbo compressors, plus the instant response of the roots. I have a friend with one on his little 2.0 ABA VW. I would go research it a bit and see what kinda gains oem roots guys make with straight up swaps. My guess would be 20%.
I know this is straight from a company but:

Then this is their actual test
http://www.kennebell.net/techinfo/ge...REWvsROOTS.pdf

One way to qualify some of these numbers. If you move more CFMs and that air is more dense (cooler) you are moving a lot more oxygen. They do cheat on the numbers by running more boost and saying its okay because their outlet temps are still lower.

Scroll down to the straight up supercharger cost and its not as much as I thought.

[Kreel]

Sadly no real update. I've been given 3 different dates for when the cams would be finished but somehow they keep stalling. I've gone from mildy upset to extremely pissed!
