Default No More Boost :(

Well, I pulled the Maggie and went back to stock over the last two days, and I have to say it feels like a completely different car. A few of the main differences...

- First gear is once again usable, I can stomp on it in first and it goes instead of making tire smoke.
- The exhaust is a LOT QUIETER without the Maggie...although its the whine that I miss the most
- Cruising on the highway between 1500-2500 feels like I am driving my Cavalier now
- Passing is no fun anymore since I cannot accelerate from 50 to 80 in one car length
- The idle is a lot rougher for some reason...I raised the idle speed to no avail. Going to have to find a solution to this one...
- When someone asks me "is that the supercharged one?" I can't smile and say "well, sort of"


I have to say, i'm not going to be able to keep it like this for long...I'll lose my mind. I hope to have a solid plan together soon, hopefully with twin turbo's providing boost. I can say that I will go with a 2 bar OS rather than try to make the 1 BAR MAF system work...which I think I should have done with the Maggie quite honestly. I also have to figure out a fuel system using a boost referenced FPR...I have a few idea's, but nothing definite yet. I'll finish figuring this out over the next two months and hopefully start getting this thing together in August.

Why not use the money for the big build and just buy a V2?

Well...its paid off for one...hard to go back to a note with a V2. Plus, I would spend at least another $5k in mods with a V2 anyhow. Most importantly, I am damn near invisible with this car...a VA State Trooper clocked me going at least 104 MPH on 95 N and pulled over a silver Toyota Camry...had something like that happen 3 times now. There is no hiding a V2...everyone knows what it is.

That's funny. I've done the same thing in my car a few times. The day I bought it in NC, I drove it back to IN. On the way through VA (not allowed to have radar detectors) I'm flying around some corner in the mountains going 90 mph and my radar detector goes ape ****. Then a Cherokee cop flies out of the trees like a ****** david copperfield magic show, and turns his lights on.

So I'm shitting my pants trying to pull the radar detector down, fumbling for the Bill of Sale since it's not even registered yet and thinking about how I'm going to have a shoot out with Officer Cletus and it'll turn into the movie Deliverance or some ****. Somehow he proceeds to pull over the little VW Rabbit that I had passed right in front of him. I know that VW guy was like "are you fn kidding me!?"

V1 FTMFW!!

It sounds like your lack of boost will only be for a short time.

My infrared CTS-V can't hide. I've been picked out of a chain of black and silver GTIs and WRXes. There really is something to be said about certain colors being "cop magnets," so to speak.

On the positive side, I usually get to have a technical chat about the design of the car and the modifications done to it that often ends in a "well, be careful out there--nice meeting you!" thing.

Can't wait to add the TVS1900. Goal is a conservative 600 RWHP.

I have the same color car as you Fuzzy but the police don't even look in my direction...
I have learned that here in Maryland the police go after imports way before American muscle. Never got a ticket in the STi unless i was doin something really stupid...lol

Do you run with your headlights off or on? Are you lowered? Stock exhaust?

I leave the lights in the auto position, yes i'm lowered, and straight pipe exhaust with an X pipe and magnaflow mufflers with the stock tips welded back on... low and deep growl! got a set of headers 1 7/8's going on shortly...

I've only been stopped once in the V so far. Was after midnight on the turnpike and I had the cruise set about 15 over. One car coming the opposite direction. Soon as my headlights hit him I saw the reflective state trooper logo light up. Gave me a warning and said slow down a little.

Normally though I don't get a second look.

I can't decide if I want to try to pick up a used maggie or just sell the thing. I like the car... it just feels like something is missing.

Op- nice to see your sticking with the V1.. looking forward to your next project.. Imo..the V2 has killer front end styling but the *** end is huge and not in a good way..

as far as cops.. i
i think its a color thing.. silver just blends in to 50% of the other cars on the road..

Now that's just funny. Kudos to you for legitimately referencing the movie "Deliverance" in a thread, LOL!

I had to pull mine off and send it back to Magnuson for some bearing work. I too slapped the stock crap back on and drove it around with a sad face. It is crazy how accustomed to the power you get. I can remember riding in my buddies stock V when I had a 350z. His was fast as hell! haha

Can't wait to see what you decide with your next steps. BTW I run a 2 bar SD tune and rock HP Tuners. If you ever need to bounce an idea off someone I'm available.

A quick tip that is way off in the future for you: Log your 1 bar MAP with key on engine off BEFORE you swap to the 2 bar MAP. This data will allow you to adjust the voltage offsets on the 2 bar to more closely match that off you stock 1 bar. Again I know that is way off but maybe you'll remember.

Thanks man, I will most definitely take you up on that offer...I know you have been tuning your own stuff for a while now and you haven't blown your own stuff up yet, so you know what you're doing, LOL. Seriously though, if you don't mind I may ask to see your tune as a baseline to populate the additional tables in the 2 BAR OS if you don't mind. Not going to be exact, but since we are both stock cubes it would really help to put me on the right track.


NOLA....props for the Kate Upton post....girl can't dance for **** but man is she hot.
