Some more COBB and JB4 Testing
I know there has been a lot of interest recently in comparing the output and performance of the JB4 when compared to the new kid on the block (COBB) so BMS went over to the dyno and did some testing, so I thought I would share the results with community as its very topical.

Again, great data! Cobb and JB4 are pretty much neck and neck.. well JB4 is putting out slightly more power vs Cobb Stage 2, but this really shows how great both tunes are!
Since the Cobb tends to rely on fuel and boost versus the JB4 which relies on more advance to get those numbers, I'm wondering what Cobb guys are getting for their daily MPG versus JB4 guys. Also, other than the mentioned downpipes and midpipes, what are the mods to the cars?

Nice numbers. Had jb3 and now switched to cobb. Both are great. Did you also have a FMIC for the Cobb stage 2+ wonder if that would make those numbers even greater.
oops, just saw it had stock intercooler Last edited by 1-2MANY; 10-10-2011 at 09:00 PM.. |

The AFR's look unsafe IMHO on the Burger motorsports to be advancing timing. I am surprised there is not knocking occurring in hi ambient conditions. I definitively think is far better for the motor durability after looking at these. Thanks for the great post!

So because Cobb run more boost, would it be safe to say a car with upgraded FMIC will make more power on Cobb than on JB4? Or the cooler charge will allow even more aggressive timing?
I wanna see some comparison between the two tunes with FBO, no meth. Please! |
