Modified Pulley Setup - Serpentine

Modified Pulley Setup - Serpentine
Right now I'm running no smog pump and an A/C delete pulley, making the whole passenger side accessory bracket 100% useless. Was wondering any anyone out there deleted this bracket for a more clean looking belt set up? If so, pics please!

Re: Modified Pulley Setup - Serpentine
I recently switched over to the serp setup and was wondering the same thing. The problem is the tensioner. The only good place you could put it is between the alt and wp. I figured in the long run, the fabricated bracket may look worse than leaving the way it was.

Re: Modified Pulley Setup - Serpentine
Ive also searched for the solution to this. I run without a/c or smog and would like to clean this up. I have not seen anything yet.
Ive considered just switching to a clockwise rotation water pump, p/s bracket and alternator bracket. I know this would mean two belts but id live with it. my concern is the alternator. do I need to switch to a v belt drive and how do I modify the connector?
would anyone have the part numbers for such conversion? cost?
to cut costs I would resell the serp drive and pieces I have..

Re: Modified Pulley Setup - Serpentine
If I was going without the A.I.R. pump and A/C, no question I would ditch the big ugly aluminum brackets and go with the old-school stamped steel brackets and V belts. P/S pump on the driver's side, and alternator on the passenger side.

Re: Modified Pulley Setup - Serpentine
i cut the section off where the air pump was , looks pretty good, was also lookin at modifying the bracket to be able to mount the alt. where the ac pump was and cutting off the top section of the other bracket also. this solves the tension pulley issue and should clean it all up quite a bit. Ill post pics if all works out, but for now i like it better already without the smog pump section there. only issue im workin out is the belt routing. also considered just swapping the ac delete pulley with the alternator so the the passanger side at least serves a purpose

Re: Modified Pulley Setup - Serpentine
i think the big brackets are a little too big, but i love havin the convenience of the tensioner, one belt, and the fact that it maintains tension under different throttle etc. when i had v belt it was nothing but a pain , and just as ugly or uglier in my opinion. when it rained, i would loose power steering here and there, etc. I just didnt like it. the aluminum brackets raise the power steering pump a little, and with the serp set up i have no more issues. depends what you like i guess, some like serp, some like v belt

CV stuff is nice
Chris Jones racing products makes some real trick setups. Toying wiht the idea of selling mine. Not cheap stuff though.

Re: Modified Pulley Setup - Serpentine
Thanks for the pics. I cannot find any serp drive modified pics and spent lots of time trying to reroute the belt to where it will work. If someone had fabrication skills, the machinery and the money Im sure there can be some sort of solution.
In my situation, it appears cheaper, easier and safer to convert from the serp drive to vbelt. my car is a weekend driver so I can deal with the two belts.
just my opinion.
I found two more pics.
this is well done and clean. this is what I want to do:
here is another pic, not as clean. I don't want this look:

Re: Modified Pulley Setup - Serpentine
All you need to do is a shorter belt and make a adjuster for the little alt bolt. The belt will go around the alt, ps, crank and kiss the backside of the waterpump.
The alt adjuster will have to be fabed up. I did one years ago but cant find it.
Fox mustang guys have been doing this kinda thing for years.
I do like the spring loaded tensioner tho, makes things nice.

Re: Modified Pulley Setup - Serpentine
The bolt that just screws into the bracket and not the block.
Yes, you can make a simple adjuster bracket that uses a bolt for adjustment.

And it needs to be reproduced.. Only 6 or so made?

Re: Modified Pulley Setup - Serpentine
I've been looking on the net for that intake. Apparently it's not common. I can't find it anywhere. It looks like it could be the basis for a great high flow unit.

I need to hit refresh before I post a new reply.I didn't see TTOP's reply until after I had posted. It guess it's a rare unit. Obviously a much better fit for our cars than the HSR.

Re: Modified Pulley Setup - Serpentine
There are only 6 of them,. I have 1, LGAFF has 1, there were 3 new ones on ebay and one of them, the one that came with the EGR adapter was bought by JerryWho. I haven't seen him around lately. I don't know who got the other 2. I was outbid on 1 of them. I still regret not bidding a whole lot more for either of the 3 ones on ebay.

Re: Modified Pulley Setup - Serpentine
Lol. I've totally jacked this thread. My apologies to the moderator. It's so crazy though. I've been envisioning an intake that is almost exactly like that. The short runners, the "V" shaped plenum bottom to keep the runner entries out of the airstream from the TB at high flow, and the plenum top angled toward the front to match the TPI plenum top profile and clear a strut tower brace. I plan to build one from sheet metal, but having that casting would save me the headache. I would still do a lot of work on it to support my target power level but I wouldn't have to start from scratch. It's even an air gap design. I hope someone does start producing them. There is really a shortage of options for tuned runner EFI intakes. Especially those that really fit our cars.
It actually looks like the photos I saw of GM's short runner concept(original concept to raise the RPM ceiling from that of the TPI, ended up with the LT1) back in 91 or so.
