boost controller was set t 15 but it was all over the place and mostly aroun 10 and 13 psi going back with better boost controller soon thou

 

Awesome! What is your setup? This my goal is around 320-350 at similar boost.

 

Isn't that Turbo capable of 20+ psi?

I'm sure it has way more in it

Rotary >Pistons

 

yea that turbo wasnt even wake at this boost thats why i am going back again and we going for over 20 psi with race gas

this is all on pump gas on 93 octane

 

street ported s5 block with s4 rotors,
atkins rebuild kit with ra classic apex seals and solid side seals
microtech ltx8
1600/850 injectors
dual fuel pumps (aeromotive stealth and walboro) with parallel fuel setup
tial 44mm vaste gate
greddy and turbo xs duel bov"s
ohh and stock block no pins or studs

 

if you are reading the boost off the microtech and it is fluctuating you need to install an orifice in the boost line to the ECU. you can and will pop the motor if it is cycling erratically and hits a lean spot.

i have had this issue occur more than once recently with the microtech onboard map sensors not filtering very well. if this is your problem PM me and i will let you know the orifice size, i don't have it on hand at the moment but i have 1 car i need to add one to and will be doing it soon. the last car i did it on i simply moved the pill from the stock pressure sensor hose to the boost line to the microtech about 2" upstream from the ECU and the readings smoothed out.

i'm not seeing much fluctuation on the dyno readings so be weary that your boost may be steady but your ECU readings may not be. what i'm trying to say is you may be holding a steady 12psi but the ECU is bouncing from 10-12psi and only giving enough fuel for 10psi intermittently. this problem did cost me 1 motor already so i keep an eye out for it.

strange thing is it only happens on some cars and not others, and i always set up the ECUs the same way. the cars that did it also had FD alternators, coincidence? i don't know.

It's normally enough to smooth out a map signal.

 

where and who tuning?

 

What turbo? or did i not see the spec somewhere?

 

speed one at Allentown pa
dave tune it
