ITB intake

[Rebeltaz83]

I hate to start a new thread if this has been covered and talked about, I did search but I may not have used the right “key words”. I am curious and I’m sure it has been done, an ITB (individual throttle body) intake setup. And a rough estimate on funds to make it work. I’m sure it’s going to be one of those things that’s not worth it unless I’m racing, or whatever or other intake manifolds, designs. Curious to see what is out there for these V10s without searching the dark cobwebbed corners of the internet lol.

Maybe the bmw adapted to the 83 would be worthwhile

The Gen III/Lambo Intake is a sexy design. Is it a good Manifold? Fine, but not great.
Porting the Gen III just seesaws torque and horsepower numbers and provides limited results. Extrude Honing...about the same.
A front-mounted E.F.I. Throttle Body style Injection setup would have all kinds of distribution issues on such a long Intake. One for each cylinder wouldn't be practical.

I sent a GEN III Intake to Wilson for modification and although they rarely reject a chance to modify one, they did reject it.
Instead, 13 grand would buy a brand new design which leaned heavily toward racing. Because that's what they do (and do very well).
3 other companies were also contacted and came back with largely the same result.

We had interesting results with the Gen II Intake on a Gen III. It provided a boost of 50 lbs./ft. of torque in a narrow r.p.m. range but NO horsepower increase. That Intake is too ugly for me and looked like it belonged on an Industrial application, like maybe a boat(?) My opinion...

I.O.W. limited options. If you know someone that understands airflow and happens to have a large enough 3D Printer, possibilities are endless!

Let me know if you have any luck elsewhere.

I wonder if a duel TBI down draft style would work better? One TBI for each bank(basically like the 8.0L only down draft) intake runners would be different length though. Or a front and rear setup for the back 5 and front 5. I think you would get more power with a down draft than a front…. Then we actually utilize the ram air induction on the hood without having a bunch of duct work. Just thoughts. I don’t know anybody with a 3D printer that understands air flow. If the 8.3 was more in demand I think the R&D would be worth it, unless it’s in the racing world, I don’t see the justification of the cost of such an intake for street use unfortunately.

If you tape some lightweight ribbon in front of the factory hood scoop and go for a highway drive, they rarely point toward it. Because it just isn't a high pressure area and is quite turbulent. Nothing fancy required but when the ribbons are straight up or pointing straight ahead, it's just not a great spot for the hope of "Ram Air".

The flat front grille and the opening for the o.e.m. airbox on the passenger side does a better job of promoting airflow into the Intake system


Put your hand on the front of the Intake immediately after a drive. It is considerably cooler than the back if the Intake. The o.e.m. setup works and doesn't draw in warm underhood air like some "cold air" kits.

That hood "scoop" does help to bail out engine heat at low speeds and when stopped though.

Yes, our Gen III has been out of production for 20 years and was limited production anyway. A worthwhile new Intake design would also be limited production (of course), and still costly.

You'd see vacuum at w.o.t. (particularly if used with high-flowing heads), if the o.e.m. Manifold was leaning towards restrictive.

Distribution is decent and it supports reasonably high horsepower levels without forced induction; so it's not all that bad!

As with many parts though, it can be improved with enough time and money. It all depends on power goals and application.

Remember years ago SILVERBACK did a test on the airodynamics and the hoodscoop intake and found just what Ronnie stated ,, the thread should be on here somewhere … Its one of the things that made me wonder about the Volant air intake system and kept me from getting one way back them … Looks cool but needs to be fully functioal as a Ram air intake ..

Yes he did a full test I'll see if it's on here somewhere .... I'm not going to look through all these threads but these are threads he posted in so could be good info in some of these

Close enough to the thread if someone is interested in search through a few ..

Cowl induction is where it’s at…. I don’t have a stock hood. “Ultra violent” is the truck I got so lucky to get my hands on. The OG builder is on this forum but has been inactive for awhile. I would love to find out if anything has been done to the internals on this thing. Top end, cam build, bottom end. It has an aftermarket clutch installed, under drive, JTS TB. It’s been to Scotty in Texas to get his killer side pipe exhaust installed (sounds amazing!) Ugh, I’m drifting off topic… down draft style intake with cowel induction. Six pack style filter setup with a hood mounted air box to seal it off from the engine bay air, and funnel it to the cowl. Lots of info on this forum. It looked like it was super active when these trucks came out, wished I was around on here then. Just graduating high school and enlisted in the army starting my life no way I could afford one these new. Been turning wrenches on anything with an engine since I was 10. Started in a body shop at 15, still doing it just graduated to bigger engines and bigger machines. Mostly diesel now and engines the size of our trucks haha.

Yeah back when this forum began it rocked like no other .. Sounds like you’re on the move with your life in a good way !

Im old school and started at 16 with my first car , became a mechanic and did all kinds of mods . Always a been Mopar guy .. the Trucks were expensive when they came out but now look at just normal ma and pa vehicles prices not to mention the so called highend perfomance cost ..

There have been a few on here with modified hods with more of a sealed air intake .. again searching threads , the media picks might turn those up .. I know one was a yellow fever and it may have Been @HemiLonestar post something up similar not that long ago .. Im sure he will chime in … others have modified the factory air intakes which appear to be sealed more to the outside air at the grill and avoid the hot as hell underhood heat ..
@Wifey might find a thread if she searches ,she’s excellent at finding old threads

You could also check the JTSVP fiberglass hoods the made and maybe still doing them …

 

[VIPR PWR]

This could be the JTSVP HOOD ,, There was another vendor that produced hood’s also but can’t remember who it was …

 

[VIPR PWR]

Modified stock air intakes.. I personally like this one !
