Need help with a intake for a r1 9.200 deck and w5 heads. Something with a thick enough flange or custom intake. Looking for a single four 4150 flange. Thanks.
 
Nobody makes such an intake with that deck height for a W5 head. And the small port and large port Mopar 9.56 deck are both junk. Buddy just had one that core shift was so bad it was unusable.
My suggestion is to use a modified for W5 indy small block intake.
Ryan Johnson at Shady Dell speed shop has done a number of these for W5 heads over the years.
I bet he could help you with your short deck deal. Give him a call
 
What about a reg W5 intake?

There are two. The large port Mopar W5 intake is a dud.
The small port Mopar W5 intake is better, but both suffer from terrible core shift issues. I campaigned a W5 headed deal for 10 years. I ended up using a highly modified Victor W2 intake.
At one time i also used an Indy intake Ryan did up. Its definately the best option. Period. I just had minimal hood clearance at the time and didnt want to change anything
Local buddy just bought W5 heads and couple of Mopar W5 intakes. One was so shifted no amount of work would have made it useable. He had Ryan do an Indy intake and will have his new mill to the track in the next several weeks.
My old car/W5 combo has now been 9.60’s at 140 on 002/003 leafs at 3200 plus.
Again, highly recommend the Indy intake and Ryan’s services. He has done a bunch of these, i know of nobody else AS familiar with doing this. Save yourself grief
 
What makes the W5 LP a dud?

Both guys who have tried them and all the other intakes on W5 heads say they are the worst choice. I believe them.
Ryan and Brett Miller. Two guys who probably know more about those heads than anybody in the Mopar community.
And then the quality control on them is terrible.
With the Indy intake available( and its a dynamite piece) its renders moot really even considering the Mopar intakes. Having run a W5 combo for a really long time and having rubbed elbows with others guys back then that did as well, you just kinda learn what works and what doesn't. Both the Mopar intakes are bottom of the food chain
The W5’s are pretty much a dinosaur now, the indy stuff runs as good or better, headers are available off the shelf( and no longer are for W5) and even though issues have arisen regards casting quality with the Indy heads, the W5 heads have generally terrible porosity and core shift. Even the later blue core plug versions are still often times leakers( ask me how i know). They come with 3/8 guides and cut for 2.02 valves size as delivered. Getting a set ready to go is FAR from cheap
Make good power, but expensive, no headers, quality issues, etc. .Better options now.

Ugh, OK, so ”The Intake issue” is there is better intake manifolds out there tha make more power.

I have been told to use the Indy intake. I’ll try the MP units first since I have them. With the LP, I was day dreaming on a multiport injection set up.
(Key words, day dreaming.)
The LP can use more plenum for sure.

I’m not to close to getting this up and running anytime soon.

My LP and head ports line up very well.
I haven’t actually checked the regular intake.
(Tomorrow maybe.)

As you said, there a dinosaur now. And that’s OK by me. All in all, there cost wasn’t a killer. I have more dollars in my Edelbrock heads.

Moving on......

Lol.... i hear ya. Couple sets i had were more than the couple sets of eddies i have had, buy quite a bit. But it depends on what your doing. w5 heads 99% of people use as a race head. So 3/8 guides need redone, most use 2.08 valve, nobody will run 2.02 valve and 3/8 guides they come setup for
Need off set rocker gear, cheaper( generally) standard head rocker gear wont work, and these days need to find or modify headers to work.
I used both Erson W2/W5 stuff and Jesel sportsman series rockers. Ersons were OK for moderate roller or less, but no longer made.
15/20 years ago when i started using them you had 3000 in them just buying a set, outfitting them, and having them ported, if not more like 3500.... been there, done that, and i look around before jumping. Before rocker gear, headers or intakes. Hard to see where an eddie would be that much, having bought both myself. You can buy eddies and have them very nicely cnc’ed at Modern for 1800/2000 bucks, and at that point all you need is better springs to run a roller.
Maybe now, when most no longer use them they have gotten cheaper, but they definately werent few years back when they were popular.
 
Yes! When they were new, they were cost ineffective for me. Currently I’d say the only draw back is rocker gear cost. Unless your head is garbage out of the gate. Or just doesn’t simply port out better than the Edelbrock head.

IF! You can actually find a 9.2/9.0 cast intake manifold, that would be very close to a miracle.
Look into a W7/8/9. IDK if that would do the trick.
 
Yep, W5 intake (small port) suffers with poor casting procedures, for sure. Oddly enough, the core shift in the piece I bought, was shifted to my advantage... for the most part. But the bolt pattern was HURENDOUSLY out of whack.
Also too, the runner exit was relatively small in relation to the rest of the runner CSA. Which allowed me to 'place' how it met the head without too much compromise, and maintain 'taper'.
And being my application was for street use, not an index, I had a lot of latitude.. (I didn't need to be too picky)

I agree, and see both of your points...
It's been frustrating for me, that the intake manifold world, for 'consumer use' has waned tremendously. The Indy is a great intake.. just wish there was more friendly competition in this area.
Mopar has seemed to have abandoned the LA, or B/RB interests.. hung out to dry, sort to speak, in favor of the 3G Hemi.
 
Years ago a buddy of mine ran a W5 deal with a modified w2 intake, he said the w5 intakes didn't work well.

Must have done a **** ton of welding.

I can't say how good or bad the single 4 intakes are. I never used one. I only used the tunnel ram. There were some things about it I didn't care for...but if you have a welder...

The modified W2 Victor i ran did have a ton of welding done on the runners to raise them. Brett Miller did it. He bought an Indy and put it on his W5 mill after taking off the modded W2 Victor. Almost no difference. He kept the Indy on and sold me the Victor. Like i said, that intake is still on my old car and has been 140 mph at 3200+ on leafs and a 28 by 10 tire. Looking forward to seeing the car at Monster Mopar at Norwalk late next month. Will be first time i have seen it since i sold it to the guy out in New Jersey.

Yes, there was a lot of welding done on that intake.
 
W5 heads w/stock intake pictures showing problems will have to wait a little more. Woke up late and swapped the 3.23’s for 3.55’s on the wife’s ride this morning, work this afternoon.
(@ work now...)
 
B3422w5 and I seemed to have had similar W5 experiences.... they are ALL SUSPECT! Personally I wouldn’t deal with Ryan J again. Was really disappointed in the way he handled our leaking short turn on #3 intake. Never once pointed fingers, but in looking to him for answers, suddenly I could never get ahold of him. Btw we sold our remaining top end (we had two sets) and I had the leaker sitting on my bench for years as I couldn’t find anyone to repair it. Gave it to a guy in Florida and he’s been chipping away at it.

They( Mopar) over the years made about 1400 sets of W5 heads. The majority of them ended up in the garbage can.... unusuable. Many others had issues but were workable and Mopar sold those. They lost a TON on the W5 endeavor
They didnt get really popular till after they stopped making them. Buddy of mine has a set he bought on here that will get making noise here in a couple weeks. Nicest castings i have ever seen, the intake he bought along with them though was literally unusable it was core shifted so terribly.
Has T&D 1.65 rockers for them and an Indy intake. Just an 11 to 1 flat tappet shortblock stroker

Smaller, less potential head for sure, but i cant wait to get my hands on the new trick flows. Know the castings will be sweet. Dont want to deal with all the license stuff again. Those trick flows should be decent enough to go lower 10’s with leaning on anything too much. Thats probably enough at my age now to be fast enough

They should have stuck it out and kept making that head. Done correctly they will make some power. As is typical, Chrysler didn't make enough of them, killed them off to early and ain't smart enough to bring them back.

Simple changes. Lose the ignorant 3/8 stem valves. Raise the spring pocket up at least .150 or even .185 so you can move the port up without getting into the spring pocket. Stop using those cheap assed seats that are too small and too thin.

I still have a full set of measured drawings for the W-5. If I ever hit the lottery I'll see about making them again, and getting ahold of Mike at B3 and let him make rockers for them...or work out the geometry issues with what we have. Sadly, you're stuck with 1.6 rockers as the highest ratio you can do (AFAIK) because you just can't make the rocker longer (again AFAIK).

The possibility of me winning the lottery is very low. So it's a pipe dream.
 
I also ran the Ersons.... got one of the last two sets. Pretty cool till we realized if we hurt ANYTHING on them we’d be screwed! My old W5 top end finally got put into use by the current owner last year. Engine is running and waiting for the car to get done. Honestly the casting on our second set of heads looked much better than the first.
 
Whoever did the castings for the W5 program truly screwed Chrysler in the keister. That is the first & biggest problem.
