2 big reasons why this is a definate no.

1: you are supercharged. NOTHING controls boost in a supercharger except engine rpm. that's it. It's directly tied to rpm no matter what. You can change the pulleys to get more or less per rpm range but that's it.

2: turbos spool with the pressure/flow of exhaust gases but only BEFORE the turbo. After the turbo doesn't matter. Removing restriction will help with hp if you aren't flowing enough but that's a different story in itself. If you have an exhaust leak post turbo it would essentially only "help" the ehxaust flow although it might sound like crap.

Lol...didn't you read my build?

210whp stock..

it seems normal in our region since we run crappy stuff like gas, and have crappy weather. but yeah, every car is different and it happened that i own a crappy one.

i've posted a dyno graph the time i did it.. look for my threads.

but seriously, with the kit on, i was only able to produce 15whp extra.

binder, thanks for the valuable info.

good to have you around this section.

i thought it shouldn't.

but anyways, i'll have to fix my H-pipe and replace my HFC's with TP's.

Update...

been working on the car today, trying to find AC leak and checking out the pipings.. couldn't find anything with the pipes cuz i don't have a leak tester, so was useless.

BPV settings looked fine, i didn't fiddle with that.

However, i did find where the AC is leaking.. it's the high pressure hose. since the pipings go from top to bottom in that area, the hose was pushed against the AC compressor's pulley, and the hose was rubbing the edge of the pulley.. it made a nasty cut in that hose.

anyways, i'm taking the car to the dealership tomorrow to see if they can replace that (in that tight area), if not, then i'll take it to the workshop that i'm suppose to take it to the first place.
----------------------------

ok guys, does this makes sense:

car was making 210whp when stock.. after installing the kit, i got 225whp with 6psi boost.

let's assume i change the belt, boost gets corrected and see 10psi, i'm sure i won't see more than 50whp extra, which is nothing compared to what's expected out of this kit outa the box.

is this correct?

you are seeing some very disappointing results, something is terribly wrong.

Something is definitely wrong...10psi should get you mid~300's to low 400whp range, depending on which dyno you use...

I got 248flywheel hp stock..
and 340 ish flywheel hp with the Vortech and 8 psi so far..
something is badly wrong..
I can only think of difference in dyno's from the US to Europe or gas???

I just wanna ship my car to some of the known tuners in the US like: IP, FP and so on...

maXmood

iTrader: (16)

problem is, i can't think of what's wrong!

even if there's a boost leak somewhere, it shouldn't drop 100whp.. because i'm building boost upto 6psi.

maXmood

iTrader: (16)

i'm not sure about flywheel hp.. is that like crank hp?

it doesn't matter what dyno u run, what matters is the difference in numbers the car makes after installing the kit.

keep me updated about ur setup, we might be on the same boat.

the belt should be in tomorrow *fingers crossed*, i'll update this thread with the outcome.

Erdem

iTrader: (2)

will do!
what about your intake temps?
BTW, I could'nt find your dyno graphs in any of your threads.. a link?

maXmood

iTrader: (16)

IAT = 42c to a maximum of 54c
MAF = 5.08v (maxing out)
AFR = goes as rich as 10.95
Coolant temp = between 90c to a maximum of 92c

do you have a dyno with the supercharger installed?

GT-ER

iTrader: (4)

Woah....that dyno shows a LOT of knock ( or timing retard ). What fuel do you have available? It seems like your problem is crappy gas.

binder

iTrader: (8)

yep, which would explain the extreme temps you had.

i'm thinking the timing was advanced way too much. unfortunately it sounds like damage was done which would result in a serious loss of power.

i would do a compression and leakdown on the engine before doing anything else with it.

do the test and make sure that your plenum is fitted well after the installation of the injectors.

check the spark plugs as well.

hang on buddy. you will get there.

maXmood

iTrader: (16)

Didn't bother to print it.

maXmood

iTrader: (16)

That's when the car was stock. I can't understand why would there be any knocks.

I brought the car from the US with a clean title and 6k on the odo.

91 octane is what's available to us.

maXmood

iTrader: (16)

I'm not sure why are you guys mixing up the stock dyno graph with my current issues? Car is running perfectly fine when it was stock. We even dyno'ed a 3.5L Altima that produced the same power.

Again, I don't think ignition timing was altered when it was stock.

And on top of that, I've done a compression test before even buying the SC kit and the results were all good.

maXmood

iTrader: (16)

Thanks buddy..

I'll have the plugs checked. I'm not sure how much they should handle when the timing is advanced.
