Boost Kind-of Working?

[CYrUs0k5]

So I was racing last night and lost to a mustang with interanls . Enough is enough. 11 PSI no more. :laugh: So I went out to the garage today and turned the boost up.... to what, thats the question. When I hit full boost it holds at about 16 psi but as I get over 5500 rpms or so it dips down to about 12... what the hell is the t25 just shitting on me or is it something else?

Thanks

its shitting on you alright. mine does the same thing, goes to 15 then falls flat on its ass at around 5.5k. time for a better turbo.

It's not just your T25, they all crap out over 5k.

Yes the t25 is often referred to as the t-too small. After about 5k rpm the t25 reaches it limit and loses all power. Also if u run 16psi on the t25 just know that pretty soon its gonna die on it. Then u will need to buy a new turbo....sucks huh. 14b is a GREAT upgrade or if u wanna get alot of power go for a bigger upgrade. Its your choice.

maybe if I blow it i will convice myself to buy one sooner, hehe. No I will turn it back down... the mustang and his internals pissed me off

Yes i know that it can be disappointing to lose to a mustang since we dsmers live to kill other imports and domestics. Jus get more supporting mods and get a 14b and u should be set. Trust me a 14b will give u much more power in higher rpm levels not to mention MORE BOOST!!! My cuz found a fmic and 14b for like $280 thats with shipping. GL looking for a new turbo. If u decide to go that way.

You're asking this after being on here for sixteen months?

The T-25 isn't a race turbo. It's a street turbo. It gives best boost where most driving is done, between 3000 and 5000.

Yes I understand that I never messed with this kind of POS turbo, no use. I was working under the understanding that it gave out between 6 and 7k rpms... No need to get upset
