Competition PDR's Blower on 5.9

[Forrest Nearing]

I assure you that blower is working before the turbo spools...

 

[RacinDuallie]

That's the idea here I believe- to have the blower generate fast airflow building abilities to then turn GIGANTIC sized turbos- at some point the blower will have to be a restiction- when 2 huge turbos are at the sweet spot- that blower will just be in the way.

What would be nice if you could divert that airflow past the blower after the turbos get into that sweet spot-kinda like a big butterfly valve-maybe psi activated-so you could automatically bypass the restriction and pump directly into manifold or plenum.

But then there's that hp loss from the belt still being there- electrically activated clutch ?

How can it if it's dumping in its own intake thru thr y-pipe?

 

[RacinDuallie]

Guys- the blower is drawing the airflow thru the turbos to help them spool-

The blower turns first... ... ... then the turbos spool as airflow pulls harder those turbos get in the sweet spot... ... ... ... ... ... ... ... ... ... ... ... ...

If you look close enough he has a butterfly valve were the hood latch is to prevent back flow to the turbo... :--)

I see a flaw it that car's plumbing,the way it is in the pics the supercharger isn't doing anything until the turbo spools. I say this because the supercharger pulls its intake air from the I/C and the goes to the y-pipe and the y-pipe goes back to the I/C so the charger is just dumping back into its intake until the turbo spools. they need to put a butterfly in the I/C side of the Y-pipe to keep it from backflowing.

 

[Scrappy]

I couldn't tell if that was a butterfly or a mount to support the pipe.

 

[LEggers]

I looked at all the pictures its clear to me he is trying to hide it in the pictures so its only my best guess but I beleive that is what it is. In another of the picuters you can see inside the tube and it looks like a valve to me.



Hell what do I know.



I do know this... .



Volvo Penta uses a supercharger and turbo on the marine diesel engines and they get great results from it.



#ad


The KAMD43 combines mechanical compressor, turbo and charge-air cooling to provide unique performance. The massive torque created by the compressor gives unequalled acceleration from a standstill. At higher speeds the turbo produces high power for excellent top speed and cruising comfort. All this performance is combined with traditional diesel strengths: reliability, long service life and overall economy. Compact and with high power-to-weight ratio, it is equally suitable for single or twin installations



It should also be noted that they use a ducting system that opens and closes with solenoids. The supercharger is shut off with a A/C type clutch at a cetan RPM.

They route the air from the supercharger direct to the turbo at a certan RPM.

I have watched one of these engines on a dyno and they are pretty cool to here run.

This engine is rated at 3,900RPM from the factory and its weight is 1,117#

that valvo/penta marine engine is one wicked engine!!!

Mark- you mention HX-35 and the Blower- so is this a single or twin set-up here?



And you report on lower RPM hp numbers- what about the good upper numbers where you would use a setup like this at the big end of the track?



Or is this design for the street?



Seems like alot of money and work for ONLY a piddy little 350 hp... ... ... ...



Hasn't 350 hp been seen with JUST an HX-35? 400h. p. as well? (high EGT's but 400+ none the less?)



What RPM's have you seen this set-up choke off?

Hey Bud,

You read it right. It has a HX35 and blower right now. The truck had a set of twins on it that we built many years ago. No hp monster, just a good everyday driver and towing rig, mild setup at best. The blower was added with the twins but for testing the twins came off and the motor changed with a good used motor. I dyno'd it with only a 35 first to give us a better base to test with as the old engine was tired and needed replaceing.



The blower was added with the 35 and I ran her with the same load and starting rpm's. Night and day difference. Snappy is a good word for it. The truck is a 5 sp duelly and it just jumps with each shift, even with feathering the go peddle.



The power comes in off idle and holds longer with this set.



This set up isn't designed for big power, just useable power. I would give up 16 hp any day for the power this makes down low (off idle to 2200 rpm) were most of us drive on a daily bases.



I wouldn't say the engine chokes off at all. It just gives up 16 hp for monster bottom end. The torque was 100 ftlbs higher in total than with just the 35.



Still a little tweaking to do but I like the results for now, seeing as no tweaking was done so far.

Hey man,

Long time no call... ... I can understand this is a snappy little set-up indeed-all that airflow down low and indeed off idle response has to be real sweet- for a driver... ... Talk to me about this set-up for higher RPM's and Torque..... Gobs of it.....

Have you-all up there done one for Drag Racing? Maybe two LARGE TWINS- Twins that have unreal cfm flow capabilities? And blower? And "Top Secret Fyre Hydrant" Injectors? No I/C?

You know a BIG FAT set-up- built to ROCK!!

 

[biggy238]

I'd love to see a setup like that run in the mountains. The grades and the air.

I want a setup like that for street only.



I Still would like to know what advantage a roots type blower has over a centrifugal.

I'd like to package a centifugal down where the altenator is, fab up the brackets and throw on a longer drive belt. (I guess you noticed i'm not a fan of the mitsubishi-eagle hood hump) Maybe I skipped over that.



I still love it. Keep working on it. I'd like to see both spin-offs of the project- One street towing app. and one maximum effort machine.

 

[jjohn]

Any news on this set up?

The Roots-type blower will build more boost at low RPM and becomes less efficient as RPM rises. A centrifugal, on the other hand, builds boost exponentially as RPM increases. If you're using a blower to build boost until the turbo comes on, you need help down low (Roots territory), not up high in the RPM band.

[biggy238]

Thank you.



I just thought maybe gearing/pulley combinations could be used to achieve the results needed. . 10PSI at idle and then top out at 4K rpm. Couple that with a large turbo for almost instantaneous turbo spool.

 

[JR2]

Any updates.....

 

[nascar mark]

The blower set up has been up and running all summer on a local daily driver. A new blower intake horn was cast up, instead of the custom "one of" that was used for the mock up. This intake blends with the hood angle much better.



I did some more dyno testing with the truck on Thursday and the results are the same, so air flow was not effected with the new intake horn.



As mentioned before, this blower set up is not for big hp but for unreal low end grunt and can be installed on any 2nd gen truck in less than 2 hrs for the ultimate street truck or tower.

 

[jabird]

Is that to say a "kit" will be offered?

i have a freind who works w/ the industrail roots style blower first off w/ a 9 hp motor the can create enough vacume to have to shut it down to take your hand off i don't know how much that might be but im pretty strong and if i couldn't take it off well thats a lot of pull so it seems that a roots style blower like this one would creat a lot of vacume which to me seems like it would light a pair of big chargers better then trying to push them plus theres the added boost down low i do have one question for peirs tho and thats if the turbos are spooled and pushing boost wouldn't the blower just compress it more



this is a great idea something ive been longing to play w/ since i had thought no one else had im really glade to hear your trying it i would like to hear more about it and maybe a few more pics it looks awsome tho good job

 

[nascar mark]

Hard to say if we will market a blower set-up. Guess it would come down to who many would be interested in a kit.
