Hi, I am new to water injection and looking for a good calculation on what jet I should be using. I've read some of the posts and some of you guys seem to know whats going on. I'm running a 1S system on a GSXR-1000 Suzuki the turbo set up is a non-intercooled garrett t-28, I've had it on for 2 yrs running between 5.5 and 7.5 psi. Pump gas (93oct) is fine at low boost I mostly run a 50-50 mix withSunoco 110. Low boost usually dynos at 215-220 at the wheel at 8 lbs we hit 237 all sae without WI. Its an everyday driver I take to the track on weekends but want start running up to 9lbs for topspeed runs to see how far into the 200's I can get. I'm expecting around 245hp at the wheel. the motor is stock 12:1 comp, injectors are 300cc/min (I THINK) I am not sure how to calculate which jet wont be to much. From what Ive' seen so far I think a .4 or .5 is what I need, leaning towards the .4. I only carry 14oz's of water and the pump seems to empty it pretty quick. Any help is appreciated!!
