Hey guys,
installed whoosh v3 intercooler this weekend and I'm pretty sure my car feels slower. There are a couple things to note. The whoosh v3 has given me about a 1 psi pressure drop, and the mass airflow has dropped about a lb/min as well going from 22.5 to 21.3, Is that whats making the car feel slower? I talked to dizzy and he said a retune is not needed despite these changes to boost and mass airflow.
I did a v dyno comparison but its hard to get an accurate gauge because my most recent virtual dyno before the intercooler was done at 30 degrees. and now with the intercooler its about 65 degrees. Im thinking Its enough of a temp change to see a slight drop in power, but not enough where the v3 will start to make a big difference. i will say the charge air temps are much more steady, before they would rise from 40 degrees to 75 after a single 4th gear pull and now they remain about 3-5 degrees above ambient no matter what.
Before in 30 degree weather I read 225 wheel horsepower consistently in colder weather with 290-310 torque depending on where the datalog/vdyno starts logging. Now I'm reading 217 wheel and 280-295 torque. Both the v dynos were started late, I have never been able to get data logging down, no matter how early I start the data and how late I end the datalog it always seems to cut off a good portion of the log. so on the vdyno, my runs didn't start until about 3500 rpm and ended about 5800. Before when logging horsepower and torque on the accessport i would get 217 horsepower and 295 torque, by 3500-4000 torque would drop to about 280. Now after the v3 I'm getting 205 horsepower and 290 torque but the torque drops to 260 by 4000. I know everyone says its not accurate but its always been extremely accurate for me.
I will say i think areas under the curve are much better. Before after hitting peak torque and power, the torque and horsepower would drop off very quickly. Now its holding much better, and there was an area after peak numbers where I made 20-30 more horsepower and torque on the vdyno. Again the accessport says something different now. So I thought I would be able to feel this power gain, but it doesn't feel any different, in fact it sometimes feels slower like I said because the turbo now has to fill a much bigger intercooler causing torque to come on later and slower. While I'm sure the v3 will make more consistent power in heat, it does appear that in colder weather the power did drop a little.
Anyone have any comments about this?
