A few weeks ago I have received a few pictures from a 9.5L 1300whp twin-turbo Trans Am owner, he has actually replaced his intercooler with water injection. He has gained a few degrees of advance, 2 psi and good reduction of inlet air and egt.
The car can now be use on the street anytime, anywhere and any months of the year without over-heating. He has retained the same power ( not full tuned yet) up to now with water injection - due to lack of time before attending the last drag meeting of the year (tthree weeks ago )- he won on street tyres at low 9s.
Here are the pictures he sent me: before, after and during - he used no less than five jets !!!
