i got to looking and wouldnt any blower that works with a carb work with a TBI if you use the adapter plate?

 

Yep. Just the serpentine belt acessory drive package that's the problem... And the associated 2-bar MAP sensor and PROM work required to get it RIGHT, but none of that is a big deal...

 

When I was at summit, they had a procharger hooked up to a holley carb by just incasing the carb with a metal housing with a tube runnin' to the blower. It was pretty trick, I figure it'd fit tbi perfect...

 

The new summit catalog has some good weiand/holley 144 blowers. They brought the price back down because of the resession I think. Or maybe no one was buying them when they raised the prices last time

 

what kinda horsepower would the holley 144 add to a slightly modded 305 tbi? if you were gonna do something like that wouldnt it be a good idea to either get bigger injectors or a holley TBI unit? also dont the blower like that take place of the intake manifold?

 

I don't believe that those blowers work with serpentine belt packages, yet. They were suppsoed to get a longer nose blower for TB's but since they already have a TBI blower for a truck, they probably won't do anything else untill they see demand.

I'd buy one for $1500 or less, FOR SURE!!!

 

ive looked at every site i can think of for the TBI superchargers for trucks...anyone know a site that has them??

 

Holley's website has it...

http://www.holley.com/HiOctn/ProdLin...-144_CSBE.html

 

It's like $3k for trucks, I think. ouch

That's a lot of money for something that wears out so fast.

 

Yeah...for that kind of money, I think I'd rather get a 6-71 blower and figure out how to put two TBI's on it!!! More boost, less money! So what if it sticks out of the hood a little bit <hehehe>

 

thassright

 

Shane Buss did this, he bought that blower for 86 tbi trucks, bolt on deal, he had to get a different hood though. Dont need a 2 bar map sensor either since the TB is before the boost. Seen it several times in fact they sell the kit with a "custom" chip so its pretty much a bolt on deal for any schmo with a tbi pickup truck. One of the mags had a how-to on it a little while ago

 

and i could swear he paid 1500 for the setup

 

The one for serpentine belts is $1709 in the new summit catalog. But the TBI ones that are 50 state legal do start at $3k. they add $1000+ just for their legality. I wonder if their legality even extends to fbodies since they are for TBI trucks.

 

whats the P/N of the one in SUmmit for $1.7k??? I thught they had one for PARTIAL serpentine packages, not entire versions???


FYI, I'd still run a 2-bar MAP sensor AFTER the blower as the vacuum sensed before the blower wouldn't always correllate (sp) with actual boost being seen by the engine. ie MAP readings before don't always correlate to the same MAP 2-bar readings afterwards... Just the evil of blowers, plus, when/if the blower decays over time, you'd have to change the prom bit-by-bit to make up for the loss of boost correlation as well.


How about FastBurn/Vortec versions?????

 

couldnt i use the serpentine belt setup even if it is for carb? just use an adapater plate right?

It doesn't say anything about vortec heads but if the ports are big enough you should be able to work something out like Shane B. did on his since he has Vortec heads and a weiand.

The dedicated TBI ones are: hly-77-144csbe-1 and the polished version on it is hly-77-144csbep1 I think they do use a carb to TBI adapter plate like the old B&M roots charger packages had. They should also have EGR in the front like the Old B&Ms since Holley bought them out.

I was just on Jeg's website and the 144s start at 2099.99. Much better than 3K

 

I just bought some E-Tec 200's from JEg's. Let's see how they compare to the other motor with FastBurn's I have. It'd be nice to get a blower NOW instead of buying an intake/brackets/etc taht I'll just sell in 2 months, anyway. OR I should do the MPFI I keep talking about... hmmmm

 

Is this kit still available?

 

Hi,
I have a Procharger supercharger on my 95 TBI suburban and I don't see any reason it wouldn't fit a camaro. The innercooler ducting would have to be different but thats all I see.
Hope this helps,
Steve

 

Thanks for the info, but I am looking for a roots style blower. I prefer them over a blow thru system on tbi. So far the closest thing to a bolt on roots blower for tbi cars is the Weiand 93-95 GM TBI truck blower.

 

not true. the SHORT version standard weiand blower, will work with the serp belt setup. it needs like a 1/4" spacer on the pulley. Do a search in the power adder board. There was a guy running one, fit almost perfect.

 

I don't really like this setup, as the blower is run off of the same belt as all the rest of the pulleys and would require either sacrificing driveability of the accessories or performance of the supercharger. With the extra long blower you can run each individually. And by bolt on, I meant an entire kit, not throwing all kinds of things together to try and make it work ok and hack everything up.

EDIT: BTW, I saw that post and was interested in the pics, but they won't work anymore.

 

well, i would consider only making a 1/4" spacer, about as close to a bolt on as you can get. giving it its own driver pully is a nice route to go, but you only have 2 choices then, the much more expensive TBI Truck version of the 144, or you get to deal with much more fabrication to get the 142 long nose to work with serp belts.

 

they also have the whipple twin screw supercharger for the 305 tbi truck, i don't see why it wouldn't work for us.

It would work, but I don't much like that design either as the throttle body mounts horizontally and just doesn't seem like a good idea to me.

 

i ordered the procharger catalog. the bonnet has excellent hood clearance. sits 2.00 inch above TB. flows 1200 cfms. uses serpentine. about $2000 retail. i like it.

 

how would the computer take to the extra air coming in from the supercharger?

 

it does, it treats zero vacume, as zero vacume. you need some some of boost referenced fuel pressure regulator, so it adds X ammount of fuel per psi of boost. (not to be confused with a vafpr, they are completely diffrent)

 

ah ok. Then I think I am gonna investigate this further cuz I would love to supercharge my 305

 

Ships tomarrow for $1799.00 + S/H.

Keep us posted, I'd love to see the buildup

 

Summit no longer has the Holley part number, its under Weiand. The Part number is 77-144-CSBE-1

http://store.summitracing.com/partde...00+&rsview=sku

Best part is that its designed to fit the OEM TBI. I'd bet that with very little work you could get it to fit the 670 Holley TBI.
