I voted for the 1/4 mile time @ 6psi. Thats my choice - no question! [thumb]
 
There is un upgrade. Its a smaller pulley. But it doesn't add too much more boost. The JRSC is not the best sc to get. I would rather have the vortech sc system with the intercooler.

ummm... you made a poll with questions in the poll? [?|]
hahahaha man I'm completely with you one this one hahhahahaha.

To who started the thread no offense this is just odd and becuz of that I find it slightly humurous. Are you having trouble deciding what question your gonna ask? Or did you just misinterpret what the poll function did? Once again not trying to knock you just curious as to the motivation behind this thread.
 
I wouldn't go more than 6psi for non intercooled system.jackson racing should switch to a twin screw supercharger and air to water intercooler now we are talking and remember the thermal efficency of the roots type supercharger is only 40% and when people are trying to change the pulley to a samller one to make more boost on a non intercooled system you are asking for trouble maybe you gain some power but ending up feeding the engine with hot air a bad thing(detonation).just play it safe with high compression engines and you know what this thread is pointless a set of spark plugs add 5whp maybe the salesman who told that was smoking something .
 
I am in the process of adding 42lb injectors to my SVT\JRSC engine and a 2.95" drive pulley. I am hesitating at this point because of the JRSC card. It takes the stock 30lb injectors and when under boost it doubles the pulses to the injectors. I believe this is for emissions purposes. I am not sure if I should remove the card or not? I am going to have my ECU reflashed at some point as a stopgap due to cost of a standalone EMS. Any technical experience in this area would be useful as I am still learning. First hand experience is even better. I did contact JR, but they take forever, if at all to reply. I also have a PRO-M 70mm MAFS with stock settings at the present time and a 65mm TB attached to a Cool-Flo\ITG intake.
 
^^^ You need a real tune.... and toss the card in the trash where it belongs.
 
I am confused with this poll...am I missing something???

Like said above, get a custom tune to get the best performance out of your system.
