    Put together a cold air induction system for my TPI unit last night. Total of $10 in parts [​IMG] garnered this.............click link below and check out the "Cold Air Induction" page. This is stage 1, figure I'll eventually get a cowl induction hood and take the cold air in there but for now at least I don't have that hot radiator air being sucked into the motor.

    Accomplishes what I wanted it to do...........been inspired by Ken Brown's (blazer72) setup and wanted to do this for months. Uses 4" flex hose - fits perfectly with hose clamps.

    man with all the cool stuff you've done to this how in the world you dare wheel it is beyond me!!! LOL

    man that TPI system looks real cool, and your induction setup looks simple yet effective.

    actually the only thing I really want is your 406 with TPI (rest is cool, but I really like that 406 setup!)

    Nice setup! Eventually I want to use a cowl-induction setup.
    Will need to fab up something to surround the air cleaner (for a carb.) so that it gets all the cold air coming from the windshield down through the hood.

    Starting to babble, sorry!

    That foil type dryer hose is pretty thin. Keep a close eye on it to make sure you don't get any small holes in it. Sucking dust into that nice engine would just really ruin your day (or year)! [​IMG]

    Good point. I already bought the heavier gauge non-foil type dryer hose now that I have the routing set. Going to put that on today..............cost now up to $16 total [​IMG].

    Well, guess I should know better than to do two mods at once. We got a 'final' chip for the computer and put that in Saturday, while at it changed the knock sensor since it was not giving codes but was showing up on the readout. Then got the TPS and IAC dialed in for the new chip............drove it home and felt the best its felt since we did the motor about a year ago. Then Monday did the Cold Air Induction.........and it does seem to run better, especially when the motor is completely warmed up. Tho it could be a placebo effect in action [​IMG] it does make sense that it runs easier when the motor/radiator is hot.

    Made one other change tonight...........got a more robust and stiffer/thicker flex pipe installed. Added bonus, it matches the TPI better than the cheaper flex hose [​IMG]. Put new pics on the site of the new intake hose also.

    Good job Franky boy! Lookin sharp bud! Just for the record...the TPI swap book from www.jagsthatrun.com has listings in the back to do the same thing....except the elbows they have are made out of the hard rubber for the joints and aluminum tubes..more than likely more than $16 bux...but a tad bit more durable. Myself and my TBI are doin fine...up to a flat 300 miles per tank right now...regardles of long hauls as she tach's around 3k at 65ish....so i guess its time to look into a R4. Stinkin about doin a cold air for the TBI on the 79...was thinkin of usin the a donor TBI car bonnett that GM used on there 2.0L corsica's...etc...as a base to attach tubing....then if i could figure away to toute the a/c suction line thru it to further drop the temps....lol. Allways thinkin. Now MR.....i don't care what you think you are doin you WILL showup at my house and caravan to Moab for the get together!!! And thats FINAL...non negotiable!

    Something to think about is to add some thermal insulation to your flex hose. A layer of foam followed by a layer of Reflectix or foil should work nicely. I don't know how much heat that hose will take in , but if you want to drop your intake temps, that is probably the next logical step.

    Does this system use an intake air temperature sensor? If so, you might want to make sure that it is mounted in a place that sees the true temperature of the intake air, i.e., isn't too badly affected by heat soak.

    Just some thoughts, not a diss, that TPI 406 is sweet!

    Oh man thanks for that link to JTR. I have been killing myself looking for stuff like that............figures I didn't look 'smart'.........right under my own nose. That will be a bonus, cause that is what I have in mind for Stage 3 of this CAI project. Stage 4 is the cowl hood idea..........but that will probably wait a while.

    As far as Moab goes...........man it sounds better each passing day. And I sure wouldn't want you pissed at me for not being there! Might have a PNW caravan going. We'll see...........

    Thanks again for the info.........good to hear from ya.

    Thanks for the feedback. I will be going with some type of rubber 'factory style' parts for the next stage of this project (see my comments and Doug's recommendation above for parts availability from JTR) , then on to the true cowl induction setup in the future.

    As far as the intake air temp question - no, this is not a MAF system, it is Speed Density, so the heat soak issue is not a problem in this case. Good point for the MAF systems tho.
