I don't get it. Since I just put in my SC CAI last weekend, this morning I was able to stomp the gas on the highway to see my boost number and it hit only 9 lbs!
Checking the stickies I'm supposed to get 11 lbs!
The performance feels alot more solid with the extra air coming in, way way better than with the drum filter and yet and I could not detect any perceptible leaks. Engine knock is alot less than what it used to be at the limit. I suppose a leak is the main cause?

 

Belt alittle lose ??

 

Nope. No belt slippage at all.

When I mash the gas it just felt even more scarier than before. Scarier meaning more power to the wheels!

Mind you, this was from a rolling start. I just turned into the on ramp at a slow pace and then I mashed it, so it was like a rolling start. I watched the needle and it only went up to 9 lbs.

 

If your blower is throwing the pulley off I would think your blower is in need of repair. Also even though your belt is not slipping you can still can boost by tightening it up.

 

I believe the pulley was coming off because the holding bolt wasn't torqued down enough. Its hard to do that while holding the pulley by hand.

 

use a socket and put it on the bolt that holds the impeller on! I found that to be the best and only way to go

 

10 lbs this morning...still 1 lb shy for some reason.

 

Are you really sure that the CAI isn't more restrictive than the pancake filter at high rpm?

What size CAI pipe did you use, and what size filter?

 

hmmm Im hitting 13.5psi with the 3.125 pulley and no my belt isn't over tightened. I've only done one sprint in 2nd gear bc Im in break in mode but I guess its the T instead of the S in Trim .

 

3" PVC from Home Depot and K&N filter #RU-1785, just like in LatinMax's cardomain site. The only difference is that I put an extra 90 degree elbow so that the filter is pointing towards the front of the car instead of straight down like in the other photo.

Should I tighten the belt a bit more? At this point I'm able to twist the belt to 93-95 degrees with my fingers.

 

should have went with the 3.5 inch

 

Home Depot only had 3" and 4" diameter pvc.

 

napa has exhaust piping. that is what I used. A rubber connector from home depot. Fits like a glove!

 

After reading the other thread about tightening the bov screw more I tried that this morning. Still looks to max out at 10 lbs.

 

it sounds like the smaller CAI piping might be a little restrictive. I'd swap it out for some 3.5" piping.

 

Hmmm...out of curiosity I'm going to put back in the drum air filter and check the number for that one. I'll post my findings on the weekend when I have time to do the swap.

 

Its probably that you went with the 3 inch pipe. The blower inlet is 3.5 so you did decrease the air flow . Im telling you the 3.5inch exhaust pipe is perfect and looks good too. YOu have already done the hard part of cutting the hole .

 

what is the filter # you guys are using for the K&N filter w/ the 3.5" inlet?

 

Its been so long.. U 3 something, Im not sure but I can try and find out tomorrow for you. Need to find the old box. The air filter is atleast the size of a 2litre or 3 litre soda bottle ( pop bottle for us northern bred). Its gotta be the biggest you can fit.

 

I'll get the part number of mine this evening. I still have the k&n box in my trunk.

 

I have to agree that the 3" pvc is the culprit. That, and the filter being crammed in against the windshield washer reservoir. Convert to 3.5" pipe and get rid of the reservoir and you'll get your lost boost back. Actually, you never lost it, it's just that the inlet side of the blower is at -2 psi.

 

Yes, it looks to be blocked on about 50% of the fitlers surface. Toss the washer box, I never really used mine anyways.

 

you guys need to figure out what CFM these filters flow. They may be more restrictive then the pancakes. Call KN and ask them. I forgot the CFM-PSI formula

 

I put my washer box on the other side...driving in the winter anywhere, even in the early spring with the snow melting, I needed it

There are rare occasions when I have needed it, I will admit to that.
A bit of bottled water works great

 

I dont even have the nossels anymore...

 

You can get any size K&N you want. Just go into your local parts store and ask to see the K&N book. The 3.5" sizes are much more limited than the 3" but there are still plenty of cones or cylinders to choose from.

 

I know this may sound stupid but do you all think that Superchargers are better over all than turbos, I know you can go more on the power side with a turbo but I am looking for a more streetable/daily driver set up, and also how much could I pick up a v2 for these days, cause I know they used to be expensive

Thanks for letting me jump in on this thread I just figured you all were the best people to ask!!

It really comes down to preference. Some like the turbo feel, others like the top end pull of the s/c. I like both but have a s/c.

 

Well I havent been in either a turbo max or s/c'd max so Im not sure but I think personally I would like the s/c better cause I like top end and I also think its a proven system that works and not to mention that turbos require quite a bit more attention. At least thats what I know of s/c and turbos. And what does a s/c run price wise and where can I get one, and also do s/c's do well with the mevi or not.

There is no doubt that a SC'er will be more streetable and not have nearly as many tuning or heat issues. Does a Turbo make more power? Yes, but it also requires a lot more attention especially with temp changes. I love my SC'er but Im pretty sure once my setup is complete it will be running with most of the turbo cars. Of course Im not running the normal Stillen setup either but thats beside the point. Basically with a SC'er you lack about 70ft lbs of torque but the hp is right on par, just different curve structures. For a daily driver I would chose a SC'er, but for a weekend car that I raced I would choose a Turbo. Each have there own trade-offs.

 

Here is the difference between a turbo and SC maxima. Me and MaximumHP's dyno both at about 5-6 psi




Not apples to apples, but power wise this is what a basic SC set up looks like compared to a basic turbo set up.

 

is that a 6 psi pulley on taht dyno?

 

Yes, I believe so.

 

did u ever get this fixed blackcat? any local spot to get the materials from or no? couldnt get the h4 inch pcv to fit over some kind of 4 - 3.5 adapter?

 

The CAI fitment is fine. In older threads everyone seems to be around 20inHg at idle but mine is always at 15inHg so I'm leaking abit somewhere. Just haven't gotten around to locating it yet.

I've got my Walbro, BEGI fmu and Aeromotive fpr ready to go in. I just need to pick up the Mityvac last so I'll be able to set the pressure correctly.

 

Hey guys,
I don't mean to hijack this thread but I have now been a part of the forced induction club for about a month (hello all ) and I am getting ready to pull the stock stillen intack and put in a cold air straight down the fender. But what happens to the blowoff hose that is currently routed back into the intake? Anyway, thanks for the input. im sure i'll be talking to you a lot in the next few weeks. Have a good one

 

can vent to atmosphere... BOV instead of recirc...

If you are talking about the valve cover hose... I made a hole in the CAI pipe and bought a grommet & crankcase fitting.
