We dyno test all our kits and post the results on the forums and our web site for all to see. I never see a true back to back comparo from the other companies.langod said:I dyno'd my GT stock and had 226rwhp. The next time I dyno'd it I had put on a K&N FIPK, Flowmaster 40s (welded in) and a Diablo Predator tune. Got a total of 12 more rwhp. For giggles, I put the OEM tune back in and lost 9 hp. My guess is that the Flowmasters added nothing because the stock pipes were in place. So the K&N was probably giving me the remaining 3 RWHP gain over stock. I'd consider 3rwhp to be pretty much an appearance mod, since you can fluctuate that much between dyno runs on any given day.
If you're getting 12 RWHP from a CAI, it's amazing.
Speaking of proof -- Do YOU have dyno sheets? I'm not trying to flame you, but if I can pick up 12 horsepower just from a CAI, the K&N is going in the trash.
Remember, ALL dyno testing needs to be done the same day and on the same dyno. This is the ONLY true way to test any product. You can not compair a dyno from Feb. to a dyno done today. We've seen 5-10 hp difference in the same car with no changes only days apart.
Ask K&N for dyno info like this:
2003 GT
A/F results:
the A/F did lean, but to a more ideal zone! Very safe.
Here's another:
2002 GT Test was done same day and at the same time. JLT vs. MAC CAI
Gains of 10 RWHP and 10-12 RWTQ were seen on this test. These gains were made over the MAC intake!!
A/F results:
Again, only a slightly leaner A/F, but well in the safe zone.
More power and better MPG!
Your reading from several JLT owners here with near the same results either in MPH or HP. If no HP was seen in a dyno test I can only assume the test was not done the same day.
The dyno doesn't lie. Dyno stock then swap a part (keep temps the same) and dyno again. The difference is the gain or lose.
So when we hear people make blanket statements like CAI's on a 2V are worthless without any documented proof we challange that statement.
Thank all,
