That motor really gets hidden by the intake and tubing and turbo.

Hank Active BB Member Registered: 09/23/04 Posts: 4549 Loc: Ca	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. MBHD _________________________ 12 port SDS EFI

efi-diy efi-diy Active BB Member Registered: 11/21/04 Posts: 1385 Loc: Calgary Alberta Canada	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.

efi-diy efi-diy Active BB Member Registered: 11/21/04 Posts: 1385 Loc: Calgary Alberta Canada	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. _________________________ 51 GMC 4.2 turbo Can't solved today's problems using the same technology/thinking that created them

OHCFbird OHCFbird Active BB Member Registered: 02/25/01 Posts: 65 Loc: Jacksonville, Fl	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 _________________________ JEFF 68 Firebird 4.2 Trailblazer engine

Alas at the 5 mile things came un-glued a bit... So they packed up early until next year.

UR50SLO UR50SLO Active BB Member Registered: 11/20/09 Posts: 7 Loc: Indiana	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

SatanicMechanic SatanicMechanic Bulletin Board Only Member Registered: 09/25/09 Posts: 3 Loc: Lakeland, FL	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!

Scott Danforth Scott Danforth Active BB Member Registered: 04/09/07 Posts: 19 Loc: Bradenton Florida	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.
