supercharged 2.5l

[mldouthi]

This looks good, what is the supercharger out of?

cobalt ss

awic core



vitron rubber for gasketing

moar!!

[mldouthi]

Almost ready for welding.


Now I just need a tig welder.

[WhatNoGarnish]

Yesss!

[Stg3G60]

sick!

[Cherb32]

Im getting moist!! lol

[kevin splits]

Are those sides different sizes?

[mldouthi]

Are those sides different sizes?

Yes, One side is slanted to allow for belt clearance, therefore it is a little longer.

Ordered a aluminum heat exchanger yesterday.

26" x 7" x 2"


I also pick up a spool gun and tank for tacking eveything in place to have someone tig it for me. A tig welder is not in the cards for me at this time. My money tree isnt liking the weather I guess.

[mldouthi]

Heat exchanger came in.

Heres a comparison picture of the IC and heat exchanger. I can see why bell ICs are more expensive, a ton more surface area.

Here is what I am thinking for the pulleys. Both will be attached to the same "bar" mount that move the stock idler (green) towards the back of the motor and a second pulley (yellow) straight out from that. The red pulley is the approximate location of the s/c pulley.




I finished the jig for the plenum. I also started tacking some pieces in place and became inpatient, waiting for someone else to tig weld it so Im going the mig and grind method

I can always make another one.

I will be having someone tig the one flange to the C2 flange, that I would not want to buy a second time. The rest will be "modular"/bolt on. That way if in the future I want to cut a big hole in my hood I and throw a M90 on there


Any ideas on getting the modular pulley mount off. I have tried 2 different pulley pullers. One pulled the threads out and the other just slips off. I will take some pictures of this tonight, to see if I can get some input/help.

Which pulley?
Also you might want to make the crank / ac comp belt your supercharger drive belt as well.

I will have to look into that. Im not sure how far forward the s/c pulley will be, if there will be a straight line for the belt to run.



This is the modular "hub" that the pulley bolts to on the s/c that I need off. Its a 4 bolt and I have the smaller 5 bolt version from zzp that I need to put on.

if I recall you change the entire snout from Eaton units. I have not played with one of those in a while.

I have the other modular pulley hub, and on zzp's wedsite it says they are press on. They want $100 for a puller to get them off. I am trying to not have to spend that for a one time use tool.

Torch plus puller?

[mldouthi]

Havent tried that yet.


New house = No torch Off to lowes at lunch.

[DerekH]

Bummer, even just a plumbers torch is probably enough. Or rather, hopefully enough.

Thats what I need to get. Benzomatic!



Work will be slow on the plenum this week, I have to get another project out for my gf's dance company by this weekend.

[Tommy<3vag]

Can't wait to see this thing in action

[timmiller05]

good progress!

A/C delete and 2.5 20V Power Steering install kit


posting here because it might be helpful for the SC pulley set up

[nickbeezy]

nice. the 2.5l is finally getting some attention. lots of new parts coming in this yr

Cool thanks.

I think I am still going to have to run the belt of the acc. belt. I dont want to reduce the wrap on the a/c (crank a/c belt) that much because it needs that wrap to drive everything.

What you could do is have a dual idler pulley made for the inner tensioner so that way you can leave it as a dummy on the main drive (which now runs in parallel with the main tensioner). Much better system than trying to make it run off the secondary acc belt.

So have the s/c run off an idler? Im not sure which one is the main and inner tensioners.


Thanks for the input.


That a/c delete looks great btw.

[mldouthi]

Like this








If anyone has any ideas, here is the default picture I am using. MS paint it up.

[DerekH]

So, double up the green. You will have to have two separate pulleys because they will be spinning different speeds but you have a mounting point at least.



Edit: changed pic to make it a little more clear what i meant. Everything is off the crank/ac belt.

The loss of rap is what I would be worried about here (redline) but I havent messed with belts much so I dont know how big a deal this would be. And the reason for concern is I wouldnt want it to slip there because then it will slow everything acc. wise down.

That definitely looks the easiest. Thanks!


I will also have to recalculate the belt speeds, and possibly get a larger s/c pulley to keep the boost in the range I want.

[DerekH]

Could make a bracket going in between the two lower idler pulleys to put the new pulley on to gain some of that wrap back.

I really don't know what exists in there for good mounting points for brackets and stuff though.

I just thought about this. Use your idea, but use a bigger outside idler. That would achive a little more wrap.

[itskohler]

Just out of curiosity, when this is all complete can I drive your car?

I can't wait to see this. Seriously, I just put extra money into savings to get this.

Good thinking! Do you know how the idler pulleys are mounted? Just wondering if stacking them will even be possible.
