JB3 info...

Tried searching for this, but couldn't come up with a good answer. Two questions...

1- With my current setup (DCI, Cyba Scoops, JB3 1.4 - Map 5, and 93 Octane), approximately how much WHP do I have and what should i expect to run in a quarter mile?

2- If i upgrade to JB3 2.0, approximately how much more WHP will i gain with the same setup as above?

Thanks for your help!

2.0 isn't about raw power gains but enhancements on power delivery and more power under the curve. There may be a few hp/tq gains but this is not the reason to upgrade or the reason 2.0 was created. Its a complete new JB3!

Go dyno your car and you will have your answers about gains Its difficult to pin down a specific gain as there are many variables. If you are trying to decide whether to upgrade to 2.0 or not then its a simple decision. GET 2.0!!!

Thanks, Mike. This wasn't about trying to make a decision about upgrading to 2.0, as I was going to do that eventually. I was just curious to know round-about answers to my questions.

you probably have 70whp over stock with that setup.

Just do it! 2.0 is night and day compared to 1.4 (especially for daily driving) Best way I can put it, it has the smoothness of stock with the raw power of 1.4

Thanks guys! I'm hoping to get out to the track sometime very soon. Now that the weather in Philly is starting to get a little nicer...just waiting for a 70 degree Sunday and i'm there!
So i guess 2.0 will have to be done ASAP!

Too many factors are involved to guess a 1/4 mile. Are you at sea level or 6000ft MSL? Is the car AT or MT? If MT, are you an experienced at the track? Do you have runflats, street, or drag radials? Is it hot and humid or cold and dry?

Basically what I'm saying is person A with the same mods and right conditions might be over a second different that person B with same mods and poor conditions. With the OP mods, map, and octane, expect to see 13's or maybe high 12's if you have a great launch.
