RE: OM617 Turbo intake - ForcedInduction - 07-04-2009
(07-04-2009, 02:56 PM)willbhere4u how much hp would you expect doing this intake manifold with a water to air inter cooler 20-25hp????
More airflow means nothing without more fuel. You might get 1-2hp out of it through pumping efficiency. To get its full effect, you would have to turn up the ALDA and full load screw a little.
RE: OM617 Turbo intake - willbhere4u - 07-04-2009
I have already turned up the ALDA and disconnected the over boost valve added a K26 with 10psi this car was a rocket off the line with the auto then it boosted quick and hard and pulls good up to 3800 RPM then the power dropped off until it shifted its going in my 240 with a 4spd and new manifold and inter cooler EGT and boost gauge.
I think the inter cooler will help! This car was noticeably quicker in the cool morning than after it warmed up.
I was hooping with a hi flow air filter good flowing intake inter cooler straight exhaust it should get the turbo to snap to life a little quicker?
RE: OM617 Turbo intake - Motorhead - 07-04-2009
I agree that the A/F ratio is the limit to the power but if you have a less restrictive flow path than the engine will make more out of early boost due to the ALDA being able to adjust, I don't know how much adjustment that could be done from the ALDA but I'm sure if F/I worked on it she would come off the line better.
RE: OM617 Turbo intake - Telecommbrkr - 07-04-2009
Anyone willing to pick one of these up for me at your local u-pull and ship it to me? PM me on how much, and then shipping would be on top of course.
RE: OM617 Turbo intake - ForcedInduction - 07-05-2009
I grab every one I come across. Right now I only have the one on my 240 and the one being modified for the 300.

(06-22-2009, 10:24 AM)Motorhead I put the stock OM617 Turbo intake manifold on a flow bench and found the flow for all 5 ports to be 336.5 CFM@28" H2O and each port as #'ed, 1-176.0, 2-152.6, 3-163.2, 4-160.2, 5-152.1. I then put a chamfer on the sharp inlet step for the turbo side of the intake and the flow hit 350, ..

The inlet lip had core shift and was thicker on one side than the other so I rolled and blended the lip, I did not spend more than 5 min. on it just to see what it would do.
Total flow after lip roll is 505.2 CFM@28" H2O

Wow, that is great information! I am glad I picked up this manifold a couple of years ago! But I am not glad it is not on my car yet!
Thanks for posting the pic on how you rolled the inlet lip. I don't know why they casted one side thicker then the other, because all the intakes I've seen in person are like that. Any rate, I wonder what the numbers would be if that side was opened up to the same thickness of the other sides?

Here is a shot of my intake. I am measuring 4mm on the thin side and 8mm on the thick side.

RE: OM617 Turbo intake - Motorhead - 07-05-2009
Yep it is the casting molds, no problem just roll that edge in and don't bother porting it past 1/2" in.
RE: OM617 Turbo intake - Syncro_G - 07-06-2009
(06-24-2009, 03:28 PM)ForcedInduction One idea I was working with was using a W115 or N/A intake, cutting off the plenum, getting a generic A/W intercooler and welding the outlet side of the intercooler to the runners as the new plenum.
Using one of these.
I like that idea - seems pretty clever and makes good use of space but I would worry that putting the IC right over the turbo might defeat the purpose of having the IC with the potential for heat transfer between them.
Would there be room enough to insulate between the turbo and IC?

RE: OM617 Turbo intake - ForcedInduction - 07-06-2009
I hope so. I'm doing something similar with my Holset and a heat shield.
RE: OM617 Turbo intake - Motorhead - 07-06-2009
I'm going to get my turbine housing and exhaust manifold/header coated as well as my down tube, I like F.I.'s idea of putting the battery in the trunk and using the space for the I/C reservoir. I can see the "FINA" intake being the norm with most 617 builds, as long as F.I. does not snatch them all up.
RE: OM617 Turbo intake - Syncro_G - 07-06-2009
(07-06-2009, 09:56 AM)Motorhead I'm going to get my turbine housing and exhaust manifold/header coated as well as my down tube,
I got my I/E headers ceramic coated but stopped short of doing the turbo housing.
The guys I talked to were concerned that by coating the turbo, too much heat would be trapped in the bearings. They weren't speaking from experience though.
I have thought about it a bit more though - seems that if you coat the inside of the housings, then you minimize the amount of heat soaking into the castings.
Also, as you ceramic coat the parts, more heat will be transmitted down the length of the exhaust - which means you should take a good look at the heat shielding and make sure u-joints and suspension bushings have some shielding from the exhaust.

RE: OM617 Turbo intake - Motorhead - 07-06-2009
Coating the turbine housings has worked well, I am sending a set out right now for a Ford GT TT that puts 1,485 HP to the tires.

(07-06-2009, 11:55 AM)Syncro_G The guys I talked to were concerned that by coating the turbo, too much heat would be trapped in the bearings. They weren't speaking from experience though.
That would be another advantage of getting a water cooled turbo.
RE: OM617 Turbo intake - Motorhead - 07-06-2009
I was thinking the same thing about water cooling also, I just want the turbine to breath fire and the intake charge to stay cool. The high flow core tor the long runner intake is about $200, I may order one soon but I want to run the intake with out an I/C first. I'm going to do some dyno testing at Westech to see baseline and then as we do the mods, when I build a fresh 617 I hope to test the engine all alone in the dyno cell but for now I will have to use the rollers.
RE: OM617 Turbo intake - willbhere4u - 07-06-2009
Well I got my 76 300d intake through the part's washer today looks like new. So I spent some time grinding off casting lines and I was able to grind that whole lip off the inlet side of my manifold with my flap disc grinder and it looks a lot more even. Not as thick on that one side I'll take pics tomorrow morning I haven't rolled that edge yet though.
RE: OM617 Turbo intake - Motorhead - 07-07-2009
Just roll that edge in, the core shift is ok. The FINA intake is going to be more than enough for our boosted 617's, when I get the cylinder head sorted out and set the port size I might not even match the intake to the head.
RE: OM617 Turbo intake - willbhere4u - 07-07-2009
here are some pics on my manifold there was a 1/8 in lip on one side only so I ground it off to make it a little more even
RE: OM617 Turbo intake - Motorhead - 07-07-2009
RE: OM617 Turbo intake - willbhere4u - 07-07-2009
the manifold I am replacing is that same manifold without EGR 1980 300sd turbo
I like the idea of sand blasting it to make it look stock I may have to try that out!!!
RE: OM617 Turbo intake - Motorhead - 07-07-2009
I know my '80 SD has a non EGR intake also, that car runs fine so I will not touch it.
(07-07-2009, 04:00 PM)willbhere4u here are some pics on my manifold there was a 1/8 in lip on one side only so I ground it off to make it a little more even
You know your intake has alot less core shift than mine does, I need to get my hands on another one to install the liquid to air I/C core.
RE: OM617 Turbo intake - Telecommbrkr - 08-13-2009
I finally found myself one of these intakes up here.
The part number is slightly different than Motorheads though, and I think the manifold looks a bit different as well. I only looked at it for a couple of minutes as I wanted to confirm that I have the right one before i buy it.
The part number is: R 617 141 07 01
The air inlet is right on the top of the inlet tube instead of on the end like the ones you guys have posted.
Anyone know what I've got?
RE: OM617 Turbo intake - ForcedInduction - 08-13-2009
It sounds like the one from a non-turbo W123 300D, not a W115.

Still basically the same manifold?
RE: OM617 Turbo intake - willbhere4u - 08-15-2009
I spent some time on the manifold this week and filed off all of the external casting marks and started polishing it up a bit it's starting to look nice!
RE: OM617 Turbo intake - ForcedInduction - 08-15-2009
(08-15-2009, 12:17 AM)Telecommbrkr Still basically the same manifold?
As far as having runners, yes. Otherwise they are very different. The W115 manifold angles upward.
RE: OM617 Turbo intake - Motorhead - 08-15-2009
I just seen a '85 black 300D turbo (Califorina car) that my friends father owned from new, it is very nice and he said he would take $1,500 for it. I don't need another car but it is a perfect driver, the intake on it is different due to the cat and I would love to put it on the flow bench.
RE: OM617 Turbo intake - Kiwibacon - 08-15-2009
You guys do realise that a turbo inlet manifold doesn't flow any more CFM than a non-turbo inlet manifold?
Even at full noise, each cylinder is only going to be consuming a max of maybe 60 cfm. So flow bench numbers of 170-300 don't mean much.
RE: OM617 Turbo intake - DeliveryValve - 08-16-2009
It's the low end increased velocity from the long runners is what I am looking for on this manifold.

Its a generic ebay 2"-2.5" 90* reducer. I tried to blot out the corny "JDM" logo but I couldn't get anything to stick to the silicone.
That particular manifold has an inlet from an industrial model Cummins welded to it. The stock inlet has only a half lip on one side and its a metric diameter slightly less than 2.5".

Gotta love those JDM logos...LOL
I should be alright without having to modify my intake manifold, ya?
Also, do I need to rotate the turbocharger so the inlet faces "up"?

Quick question. Can a radiator hose do the same job here or does it have to be the silicone stuff? I ask because well, i can find a hose for the cost of nothing.
RE: OM617 Turbo intake - willbhere4u - 05-25-2012
Radiator hose will start ballooning
RE: OM617 Turbo intake - lgreeley83 - 05-25-2012
Would it last a couple of months?
Been doing some reading. Funny stuff people are doing to save cost. I think i will do silicone.
RE: OM617 Turbo intake - sassparilla_kid - 05-26-2012
Okay, sooo other than being able to add an intercooler much more easily with a w115 manifold, are there any other real benefits? I'm wondering if I should get one of those silicon adapter elbows so I can install the one I have in the garage on my car. It already has a non-egr manifold on there so I'm just wondering if it there are any additional gains to be had from simply swapping it on
RE: OM617 Turbo intake - lgreeley83 - 05-26-2012
Looking super cool! I would do a b4 and after on a dyno but i am afraid my car will blow up.

You think so? In a cooling system they hold anywhere from 16-21psi on the daily, with hot coolant flowing through...
RE: OM617 Turbo intake - sassparilla_kid - 05-29-2012
maybe in a month or two I'll try the w115 with radiator hose and let you guys know the results I get

The main reason you don't wanna run regular rubber hose is that the oil, etc in the intake from egr/crankcase vent/Turbo seal&bearing leaks will weaken it...thus causing the ballooning... that being said it'll still last several months as evidenced by many wastegate hoses I've seen used on cars that didn't have the proper material...including a few of mine.
RE: OM617 Turbo intake - Captain America - 06-12-2012
Guess I assumed that the EGR and Crankcase vent had been eliminated from the intake haha
