Awesome, thanks gnuts! I'll be going shortly to a muffler shop to get the bung welded on

2ndgentl

Ok, so I got the AFR gauge all set up. At an idle it's right around 14.6. At WOT it's at 11.5 then slowly creeps to 12. When I'm driving normal around town it fluctuates from 14.5 to 15.2. Sometimes while I'm driving it in Max's itself out in the red zone meaning that it's running very lean but then I just popped the throttle real quick and it goes back to 14.5. I know they are never steady they're always bouncing around but let me know what you think

2ndgentl

So, my AEM digital boost gauge at WOT hits 5 psi then drops to 4 psi then 3 then 5 then 4....you get the idea. I put a mechanical psi gauge and it's more steady. It hits 5 psi then drops to 4.5 psi and stays there until it redlines. I'm not sure how its dropping, maybe a little belt slippage?!! I'm almost tempted to put the stock IM with no spacer on so that everything lines up perfectly just to see if the psi changes. Car still pulls very hard though! I have Hankook Ventus RS-3 tires up front 235\45\18 with 140 tread wear (sticky tires) deflated to 23 psi and they still spin from 40 mph to 60 mph if I punch it in 2nd gear. 1st is useless past 1\4 throttle

^ Looks like you are having fun with it!

4.5-5 psi may be the max you will achieve with the stock crank pulley, 3.0" base pulley and 3.33 SC'er HBP.

If you have a hankering for the alt. HBP, South Florida Pulley can make them below:

If you can get a camera in your car and time permits post up a video of your completed project with a 1-3 gear run, hehe

Here are one of the few times I got traction in 2nd, on a new paved Road. I'm also granny shifting it still with the new clutch and pausing for a second in between gears before flooring it.

Thanks for the video.



It's amazing how fast the tach climbs/whips in 1st gear with the lightweight crank pulley and Aasco FW. It also appears that the XLR8 clutch/pressure plate are grabbing strong at the end of the 2nd gear pull and all through the 3rd.

LOL, and that's just with 4.5-5psi and, of course, the 09 TL mani. and 76mm TB.

Very nice and congrats.

Any thoughts on the pursuit of a tune or are you going to 'roll the dice' with the CT ESM for a while and have fun?

2ndgentl

I would like to get a tune on it but I think I'm going to get a bigger crank pulley to raise the boost a little before I get it tuned. Right now the air fuel ratio is actually perfect, meaning it's in the safe Zone for me to be driving it around. I still haven't run any cars yet to see how fast it actually is against something, but from a dead stop I think a Dodge Caravan will take me....lol

Which one do you have in mind?

Or do you mean alternator pulley?

2ndgentl

I'm not sure yet, I would like to be around 7 - 8 lbs of boost. Not sure which way I would have to go, bigger crank pulley or bigger supercharger pulley. I'll have to do some research. Not sure if they make a bigger crank pulley for the CL

gnuts

I'm just thinking about your lower boost reading. I wonder if your manifold and spacer have lowered the reading. Also you have no cat right? A freer flowing exhaust will lower boost readings also. If you have the stock manifold swap it on without the spacer and see what happens.

2ndgentl

I was thinking the same thing about the intake manifold and spacer, remember with that newer intake manifold and spacer the S\C doesn't line up 100% to the IM. I'm going to put the stock IM with no spacer just so everything can line up perfectly and see what the Boost gauge reads. I didn't know deleting your cat can give you faulty readings on your boost gauge, that's good to know! I have a test pipe where the cat used to be and got rid of my mid Muffler, basically it's a 2.5" exhaust from the headers down then it Y's to the Comptech mufflers. So my exhaust is very free-flowing

zeta

iTrader: (1)

OMG. I did not realize you were cat-less.

In for updates on what you find when testing the stock IM. Hopefully there is another 1+ psi to be found.

2ndgentl

So, does this mean my boost is reading lower than it actually is putting out?

zeta

iTrader: (1)

^ Well, I'll tell you this. I bought a freer flowing cat from XLR8, back in 09-10 if I remember correctly, installed it on the CT B-pipe and can't seem to remember if I have ever hit 6psi since. I've had my boost gauge set at 6psi to flash the red light alert and haven't seen it in quite awhile. When I had my stock cat, that appeared to be a 'bottle-neck', and 6psi was frequent. So, maybe that freed up resistance in back pressure from the new 'high flow cat' and lessened my overall boost. Now that I think about it I had more occurrences of 6psi running the stock cat. There is a possibility, however, I'm no expert, gnuts might be on to something.

Was your buddy who sold you the SC'er running a stock cat?

This is a good read: https://www.google.ca/url?sa=t&sourc...NvNDOIpW8I2KQA

"Contrary to popular belief a restrictive (low flow, partially clogged, or clogged) exhaust system does not decrease boost. It actually
increases boost. Since the engine's breathing capacity is reduced, the supercharger sees it as a "smaller" engine and is able to
build up more boost. The cure for this problem is to try a larger supercharger pulley to slow down the supercharger and build less
boost. Plugged cats are dangerous. They can cause a boost increase of 20psi or higher which can blow out engine gaskets and
seals. The exhaust has to go somewhere and if the engine doesn't stall it can also break pistons and rods. So if you have a super
sensitive and accurate boost gauge, you can tell if those headers, exhaust, or cats, really make more HP and lower boost."

lol, per the Kenne Belle 'Low boost Causes & Cures"

"Kenne Bell superchargers are designed for billet steel friction drive pulleys. We do not recommend the use of ANY aluminium pulley because of the excessive wear and incompatibility with our steel friction drive components. Aluminium pulleys can slip and shear off the pulley bolt because of the soft nature of aluminium. Avoid them like the plague. The cure for this problem is to throw aluminium pulleys in the trash"

I always wondered why Jon Bond Performance had their steel alternator HBP's listed for $499.99.

2ndgentl

I guess this all makes sense if the exhaust flows better the Boost PSI on the gauge reads lower. This doesn't mean that your supercharger isn't putting out 6 pounds anymore, it's just escaping a lot faster out of the exhaust so it's harder for the gauge to read the accurate PSI that it's producing. I bet if I plug up my exhaust with a banana I'll get a much higher reading on my boost gauge. Lol I mean, if you think about it it makes sense. I think the guy who had my supercharger has the stock cat, if not it's a higher flowing cat. I just texted him so I'll see what he response to later on.

2ndgentl

Thanks for finding that thread, lots of interesting topics discussed on it!

2ndgentl

thanks for that link, I think everything I need to know is on that file. I'm going to read the whole thing, there's a lot of good information there! So I would think having a free-flowing exhaust is actually better for the motor. Especially with only 6 pounds of boost

2ndgentl

Yep, just talked to the guy that had my supercharger, he was running the stock catalytic converter

So will you forgo reinstalling the stock IM or do it for 'poop and laughter' just to see the result?

In addition, if you decide to change the 3.33" SC'er pulley to 'up' the psi, how much smaller will you go?

2ndgentl

I'm still going to put the stock intake manifold on there for "poop and laughter," I just wish I could get it dynoed with both of them to see the difference. It's a 15 minute job so I'll do it sooner than later and let you know if the Boost changes. I'm not sure what size pulley I will go with if I decide to change the supercharger pulley. What I need to do is get it dynod now while the weather is still cool and see what kind of numbers it's actually putting down

I found this one for you. Don't know if it will fit though 4-rib 3.12":

https://www.summitracing.com/parts/vor-2a034-312

2ndgentl

Damn! That looks identical to my pulley! So how much more boost do you think I would get? I'm thinking 1 - 2 lbs which should be perfect. Thanks Zeta, I'm definitely going to consider that pulley

Marcelechka

3.12" is pushing it.

Terry from SFLP recommended making me the 3.2" pulley based on my configuration at the time. Had to gain what was lost due to plumbing... 3.275" alt + 3.2" blower shaft will net 10 to 12lbs without an intercooler.

As mentioned before, you'll need bigger injectors & a method to tune.

Heat soak will also be an issue (specially in FL) as the blower is operating well beyond it's efficiency range to be effective.

zeta

iTrader: (1)

lol, that appears to be the lowest Vortech goes for the 4-rib and next step down from their 3.33" and 3.70".

As far as how much psi is gained, if you look at Kenne Bell's link provided by gnuts, 'A 1/8 change in pulley diameter is approximately 1psi of boost...' using the 3.0" alt pulley:

SC'er pulley 3.33"=84.582mm
SC'er pulley 3.12"=78.248mm
=6.334mm smaller.
6.334mm=.24937008 inches=1/4"
1/8"=.125"
2/8"=.25"=2psi +/-

I will say this and as you already know, if you 'test' and ultimately end up 'running' with the 3.12" pulley, you should strongly consider investing in tuning for long-term safety of your project.

2ndgentl

I definitely need to get a tune, but if I'm going to replace the pulley I might as well do it after that. I have to bite the bullet and just take it to Orlando over at Kings Performance and have them do it right. I'm sure after that having the AEM EMS I'll be able to mess with it myself if I decide to do anything else to it

zeta

Correct me if I'm wrong in this alternative view of thinking and generally speaking. Right now, the way I see it, in regards to pulley sizes, you currently have somewhere near the opposite size configuration that I have with the stock size crank pulley, Alt. HBP 3.275" and the base 3.8" SC'er pulley, thus your psi readings are coming in at/near 5 psi. However, you have a lot more of a 'freer flowing exhaust' system that, perhaps, skews max. psi. readings.

You have the stock size crank pulley, base alt. 3.0" and 3.33" higher boost SC'er pulley. The fact that your alt. pulley is .275" smaller than the 3.275" alt. HBP reduces overall psi to come in around what would be expected with my set-up 5.5-6 +/- some psi.

If you reduce your SC'er pulley even further to a 3.21" high boost size, utilizing the 3.0" base alt. pulley, then you gain that additional +/- 2psi that you want to be at. This sets you in between, even with your freer flowing exhaust; 09 IM and 76mm TB, the 5.5-6psi and 9-12psi that Marcelechka has attained.

zeta

iTrader: (1)

Just offering alternative views/suggestions here.

If you look at the part number prefix for the 3.21" SC'er pulley; 2A034, it is the same as the 2A034 on your current 3.33". The suffix is the only thing that is different, which designates size; therefore, it will fit your SC'er driveshaft.

With that said, IF you decided to purchase the 3.21", to up your psi by 2, and take it with you when you 'pull the trigger' to have it tuned by Kings Performance in Orlando (321-235-2699), they can tune for BOTH pulleys and have two separate MAPS saved to your new AEM EMS, that you could alternate through, if that is your desire. Those guys are the experts and they could give you the accurate advice as to whether that would be needed, or anything else, like a Meth kit for 'heat soak' cooling etc.

Again, in the mean time, if you have a free Saturday, or maybe during the week day;, you can coordinate an appointment with Sergio, the one who tuned Ryan's car (RJ Poseidon), drive over and get ALL of your questions 'under the sun' answered by the pros 'who know'. Tell them your wants/needs/goals for the car and let them itemize a price list for the 'turn-key' package and all that's left is the hard part, paying for it, hehe.

2ndgentl

How is Marcelechka getting 9 -12 psi? Is there more restrictions in his exhaust that's bumping his psi up? I wonder what numbers he's putting down on a dyno, It should be impressive with that much boost. Also, what injectors he's running, what kind if tune he has, ect...too many questions, I know...lol

2ndgentl

Thanks Zeta for all this info!! I guess I don't want to get too crazy with this since it's my daily driver but 6 - 7 psi would be great! Any recommendations on injectors for that kind of boost? I kind of want to be ready when I drop the car off at Kings Performance, but I guess I should call them first and talk to Sergio

zeta

iTrader: (1)

I was speaking in general terms in regards to his set up. Since he is the psi title holder for a SC'er application on Azine, I'll let him speak for himself, lol..

That is the best advice I can give you at this point, you have arrived at the juncture to where you need to talk with real tuner experts like Sergio at Kings. If making two trips over to Kings is a bit much to map out how to proceed, then when time permits, either email them or call and mention Ryan's name to get the tuning relationship initiated. They can certainly guide you with your valid questions far better than I or gnuts or Marcelechka ever could on this bloviated text forum, hehe. He will be able to tell you if new injectors are needed for your target range of 6-7+ psi, what kind to buy etc.

Marcelechka

Most of the info of the build is on the old thread: https://acurazine.com/forums/second-...thread-864252/

As Zeta said, reach out to Kings to point you in the right direction. I'd also have a local mechanic / shop on hand just because... from reading this thread, you drive a lot harder than I ever did from the occasional ramp / hwy pulls here & there; so yes - things will break at the HP threshold in which you are seeking. At the end of the day, be ready to devote time, patience, & money into this project.

I just read all 11 pages on your thread, very nice build!! Car looks amazing! I'm not sure exactly what I want to do though...I can't really imagine boosting my car anymore than 5 psi. I mean, it sounds good having more boost but I have absolutely no traction in 1st or 2nd. I can't even do a 40 mph roll with anyone because it annihilates the tires when I punch it. More boost just equals more wheel spin. I don't know how anyone is able to get these cars to hook up. Maybe I lightened my car too much?!! And the only way to put wider tires on this car is to cut the fenders and put wider fender flares on it so that they don't rub. Remember, I have 18x9 Rpf1's on my car. I guess I could jack up the car to fit wider tires, but I like how low it sits. Also, I've always loved the looks of an intercooler, but I didn't know that you can lose a couple pounds of boost by adding one. I would love to install an intercooler on my car, but I don't have much boost to spare...lol Oh, by the way, those video links don't work. I saw the videos on your thread but not sure if the ones you posted here are different ones

2ndgentl

Maybe getting the 3.12" pulley and installing an intercooler will keep me right around the same psi where I'm at now, but with an intercooler it will benefit the engines temps especially here in Fl. Any recommendations on an intercooler that fits and looks good? Would probably want to go with 3.5" to 4" IC piping. Also with an intercooler installed I'm assuming a blow off valve can also be mounted somewhere

I kept Marcel's info on his setup shown below. You may lose a little boost from the added piping but the denser (cooler) air should make up the power. Do you know what your IAT temps are?
