Inliners International Forums General Discussion Blown and Injected 4200 turbo project...

All I have to say,,,bring some sticky tires!!!

And have fun!!!


MBHD

Yep finally have a use for the goodyear drag radial slicks.... 9x30"

I have some video - just got to find time to edit it... the cam operator was ummm a bit green at it...

Need a few days to rewire and make it tidy but it works.

It looks as though you have 2 sets of injectors. What is the size for the 2nd set?

That motor really gets hidden by the intake and tubing and turbo. Goodluck at the track. tom

Pretty serious looking setup.

If you were to do it again, would you cast the runner 'elbows', or try to fab them?

The runner have several complex curves in them that make them hard to fabricate. Actually I'm working on tooling to cast the entire intake from the head flange upto the bottom of the plenum.

The second set of injectors are 12 x 72# - will be used on high boost to fuel the motor with 100% methanol.

That old truck is going to scare the crap out of some people! Maybe even the driver. I am truly amazed at what you are able to do. Tom

Looks good,,,but,,,,don't take this the wrong way,,, but not sure the air entry between into # 3 & 4 cylinder intake runner is a good design.

Do you have some type of devider plate or difuser in the plenum?

All the turbo books & info I have gathered never recommend blowing straight into one port or two for that matter.

Just wondering if you had no room for any other throttle body positioning?

I do hope it works for you.

Hank,

I discussed this very topic at length with a retired university prof that taught automotive engineering and did a lot of turbo work in the 70's, the direction was the effect is minor and not worth the headache of a diffuser.

I still wasn't convinced though until I happened to stop at RCTS the local high end tuner shop for high dollar stuff (>$150,000)cars. On the floor was a plastic BMW intake off of a factory supercharged M3 (6?)that had split from too much boost.... well not only didn't it have a diffuser - it had huge tapered trumpets inside the manifold pointing directly at the throttle body!

BWM has been building inlines for a long time so I took my clue from them and deleted the diffuser. So far no ill effects.

Perhaps over the winter I'll pull the turbo manifold and install 6 thermocouple wells so I can measure the EGT's which will tell whats going on.

Well hind sight is 100% perhaps putting it horizontal would be better for clearance. I was trying hard to not have anything hanging over the valve cover.

I'm considering moving the master cylinder and brake booster under the floor to clean up the firewall if this comes to pass, it will open up a lot of possibilities where to locate the TB. Maybe even redo the plenum so its a tapered upside down U and mount the TB outboard of the engine... all just random thoughts right now...

Thanks for the feedback though.

Here are the ones that Toyotas make

I think Toyota are the ones making much more HP then BMW's in there turbo 6's.
Also the Supra engines can handle up to 850 HP with a stock long block IIRC.

Not saying that BMW's are bad.
My good friend is a designer for BMW.

Some quick video...

Hmmm something to consider...

My plenum is .120 AL so not so hard to adjust the design ...

It sounds good on the dyno!!
Who knows,about the way it is now,,,maybe it works better than most other designs?

But,,, with that being said I will bet the pic of the aftermarket Supra intake manifold will give you the most HP.

Glen Self had a simular intake as the aftermarket Supras run on that fast 1000 HP 66 Nova wagon w/the 4.2 engine in it.

Thanks for the reply, a fully cast manifold would be cool.

It sounds great on the dyno. I see what you mean about how much it torques up under load.

IIRC, you boxed the frame?

The manifold will be cast from the head flange upto the plenum base - the plenum top/ends is left for the end user to faricate to fit the space available.

The frame got partially boxed where it was bent to match the nova front clip and where the clip was attached.

Thank you.

That sure sounds like a lot better setup than trying to fab the whole thing (here in the garrage).

Do you have any idea how much they would cost the end user (as you described, ready to finish the top and sides)?

Not yet - I need to finish the tooling and send a positive to the foundry for quoting.

Also the price will depend if the purchaser needs the flanges machined etc. the raw casting would be less $$$. Leaves more DIY but would save $$$ as I have to farm the machining out to a commercial shop and pay the going rate.

How was your day at the track? Hope your not online from a hospital. Tom

I Second that!

When will you posts your results from the dyno?

I will guessimate 400-475 HP range, that's a low ball guess,,not knowing how much boost or anything else,,just a guess ;-)


MBHD

With a dry-flow manifold, the inlet location isn't as critical, especially if you keep the low presure area behind the throttle blade away from one or two particular cylinders. Another technique used to fight this can be seen in the Self manifold- the use of a tapered plenum from the throttle to the end cylinder. You shouldn't have any issues with flow as long as you have sufficient plenum volume and your throttlebody doesn't become a restriction (it probably already is).

I'm so glad to see you making progress- my build has stalled for now. I want to get on the cam purchase if that is still open.

Have you had a chance to monitor any backpressure #s? I'd really like to see how that turbo manifold flows.

Nice work! I can't wait to see the torque #s.

Jeff

Thanks again.


Hope the track day went well.

Just left the Salt this afternoon - the Black Opel Team made a best yet pass at just under 198 mph E/GMS 4200 vortec. Alas at the 5 mile things came un-glued a bit... So they packed up early until next year.

My guess is this might be the fastest N/A inliner pass.

Jeff,

Cam buy is still open - but not for much longer.

Another round of track testing..... knocked 0.5 seconds off and added 6 mph.... 1/8 et is now well under 8 seconds.

Nice work!

What was the final HP & torque numbers from the dyno session?

MBHD

So,,,,,,whats the latest???


MBHD

Busted radiator... I have to do something to isolate the rad from the rad support - the rad is acting as a torque brace.. the top tank split.

The seasons done here so I'm onto other projects until the new year. Got to take a break from the truck for a while.

As for the dyno #'s I'm thinking of writing an article for the 12 port....

That would be the best place to put the news. I will wait patiently to read about it.

For the ONLINE inline bunch, you may not know there is a club that supports this website. The dues collected are what make it happen.

Because of this club, there are also many chapter clubs across the USA and they hold regular meetings and events. Fun stuff.

With membership you also get a great club magazine. Tom

Quick question,what size valves are in your ported cyl head?


Thanks

MBHD

Stock '06 size

intake 2x 1.540
exhaust 2x 1.340

Nice work!

I think I would change the throttle body entry from the top there to the front of the manifold.

Cheap way to find out how the air is being moved and how even it
is being moved is to get a leaf blower and attatch it to your throttle body. Turn on the blower and open the throttle. It'll shop you how even the air flow ballance is. If your getting more air in the 3/4 cyl and less in the other you'll lean out in the middle and rich in the ends. If you have sequential injection you can tune each cyl. (Like you said.. EGT in each hole) will
be able to "See" where your ballance problem is.
Your Intake design is great.. just move that throttle body and
it'll be awsome!
You didn't post your actual MPH and ET for 1/8m....
~Scott

You've certainly earned it, thank you for sharing all this with us.

Heres a little idea, you may or may not ever have a problem, but if you do have a problem with those couplers, check some med/heavy duty truck parts stores, you can get the intake charge piping connecters/couplers replaced with some spring loaded ones like they use on semis. Just a lil tidbit, incase it would help!

Not to criticize, however SatanicMechanic is correct. The black EPDM hump hoses your using are not for the boost side (they will blow off). You need to have the 4-layer nomex/silicone. Anything over 4" long should have the wire reinforcement rings. Also, if you need a good tube bender, let me know. I can point you in the direction of the guys that I have used for years on Diesel engine installations.

efi-diy,

Reading this old post.

I was wondering if you have any pics of the inside of your plenum?

Or even pics of all the pieces made to make your intake manifold.

I only remember seeing just your casted intake runners, nice B.T.W.

Thanks

MBHD

Hank, it's in here.

https://www.inliners.org/ubbthreads/ubbthreads.php?ubb=showflat&Number=64612&fpart=1

Pretty.

Thanks,,but,, Thats my post.

I was asking to see EFI-diy intake plenum pics & the pieces bolted to the plenum. Not sure if he ever posted pics.

My mistake, I thought some of those were pics of one of his intake projects.

I must have been half asleep to post that.

Nexxussian,
not a problem, I have brain farts all the time LOL.

Here are some other pics he sent me.

Billet velocity stacks?

He had told me he does not have any pics of his velocity stacks. I tried.
