ive got the turboxs... i think its great, just follow the instructions, and once on just turn it up slowly until your where you want to be (im at 21psi)...

just make sure you have that boost gauge in there and your set

Thanks, I didn't know how a turbo works... If I stop the full power from being accessed I won't be ripping on it every 6 seconds. Since I'm the only TT I see in my county I wouldn't wanna start by giving owners a bad name. I rather listen to the rumble of the exhaust at 3k than floor it & possibly injure someone else.

heheh.

going back to the comment about my comment, yeah, you'll make more power, but the more boost you run w/o actually planning anything more than just turning up the boost, the more heat you make.

The secret word for today is 'efficiency island'.



The farther you are off that little one in the middle, the less efficient your turbo is. If you want to blindly screw with your car, at least try to keep it off the line to the left.

Its just the law of deminishing returns. Just because the gains become less, doesnt mean they arent there. 20whp is 20whp regaurdless of iat's. Plus when you add in a ic, there is more whp + the ability to increase timing a couple degrees

If the car is producing full boost on part throttle/fuel this could equal some serious damage.
In real terms, I had some serious bucking issues on part throttle and a nasty burning smell. Scary stuff for sure!

B&S mbc's suck ***** on such a small turbo. However when you get to something that actually has lag to it (gt28rs, 50trim, etc), they are a huge benifit since they can help build boost faster and not instantly.

I'd have to agree with CincyTT on this one.....I could care less about V.E. especially with a stock turbo !!! If you want efficiency, take off your turbo =). For example look at turbines, they're 1 big turbocharger stuck to a wing on an airplane......V.E. suck but makes "lots of power".

to put that ^ into perspective, you chip a ko3 and you are out of its efficiency range.

I run a Hallman's MBC that I had in my old 2g eclipse years ago.....STILL works great. I have it set to 22PSI. I have no issues with partial throttle and have been running it for months now. There is no jerkiness to it at all but that is my own experience.

Thanks a lot for the info people! After reading the mods list it looks although i will need a better FPR before i think about turning the boost up to what yall have it at!!

I am installing it tomorrow with my boost gauge, will add pics and let you guys know how it went, thinking about 18psi.
