How do i stop my boost peaking so much?
It peakings 1.2bar and will only hold around 0.9bar, a diff of 0.3bar or 4-5psi seems alot to me
Its a 48/55 T3 with a Radtec FMIC, OFAC EFi with an air filter and exhaust. Using an MBC to control the boost.

I want it to hold 1.2bar really, but i can't peak anymore as it boost limits...
So peak and hold 1.2bar or at least hold 1.1bar!

 

Hiya matey,

MBC, is that a manual boost controller? When i first got my car it had a manual type boost 'controller' and it did similar things to yours, peaked at 21 and dropped to 16-17.

With an electronic boost controller like a gizzmo IBC it will hold 20 with a peak of 22ish. At the moment my gain is too high to i peak at 25 and drop to 20, but tbh i think its partly because i've reached the limits of my turbo.

I'll PM you a later on mate about things.

Rob,

 

Yeah its a turbo smart "boost tee" recommended by MSD... i was thinking of getting an electronic controller in the future. Is it possible to peak and hold a boost level say 20psi?

 

is it this one mate http://shop.motorsport-developments....alve-294-p.asp

im looking in to getting one, are they any good

 

Yeah they are really good, a good looking and purposeful little mod. The only thing is i don't know if its the cause of my problem?

 

Always worth checking the actuators still sprung tight... fact it's making the right boost probably means it fine, but still.
