Setting up my old GQ Turbo properly
Posted: Sat Sep 15, 2007 8:21 pm
Newb to this forum stuff.
Have had my 88 GQ for about 10 years, fitted a safari turbo and intercooler around 9 years ago. Modified the PTO setup around the intercooler pipes.
Have just fitted an EGT and boost guage. Found that all this time I was only getting 6psi because i never set the wastegate up properly (it was always slightly open before). Fixed that up and it gives 12PSI boost standard. Have also just fitted a boost controller but not sure i need it. 12psi seems ample to me. One thing i noticed is that the EGT is much lower now because of more air.
I had fitted the EGT sensor after the turbo and kept it below 520degC but have today fitted it before the turbo as i saw on one website that you can get as much as a 200degC temp difference across the turbo.
What limit of EGT should i keep it below with the sensor before the turbo?
Because with the extra boost i want to enrich it some.
