In another thread mar1nasr said he's up to 308 hp with the K&N air intake and a buddy is measuring 350 hp at the wheels with the K&N and a Fox exhaust and headers. This is all on the 4.0 V6. I'm not familiar with modding this engine, but these gains sound incredible. If you're getting 350 hp at the wheel, then I believe you're > than 400 at the crank. I'm shocked that you can get +134 hp from these mods.
Does anyone have dyno print outs or other data to show what gains they actually achieve?
mar1nasr, feel free to elborate in this thread as I did not want to hijack the other one. Thanks!
Intake and Exhaust Modifications
Moderator: volvite
I put the K&N intake kit on mine and got little gain for the "14+ hp gain" claim. I have dragstrip slips before and after that showed a best gain of 2/100 of a second, and .32 mph, in 1/4 mile ET.
I am about to do a custom cat back exhaust, with a Magnaflow muffler. I am curious to see if it combines well with the intake kit to give a more noticeable increase.

Re: Intake and Exhaust Modifications
There's no way in hell. Let me repeat that, no way in hell. I can't remember what Carl's numbers where when he had the supercharger installed, but I don't believe it was even close to the numbers mentioned here, although I'm probably wrong. Age & memory don't mix well.AZ_Path wrote: If you're getting 350 hp at the wheel, then I believe you're > than 400 at the crank. I'm shocked that you can get +134 hp from these mods.

Okay. It makes sense now. UAE rating is 291 hp stock.G35TR wrote:mar..., aren't you overseas somewhere, like UAE or somethng? I'm beginning to think there is a difference in measurement perhaps?

US is 266 hp stock.

Obviously there are significant differences in the rating criteria. I figured it was too good to be true, but I got a little excited for a minute.
Nope im in Dubai,,Arabian automobiles displays the vehicle as 291 Gross, thats the power the engine makes without any accessories swtiched on or connected to it...But 266-270 is the actual power of the engine after everythings finished sucking the power outa it..
But 13 hp from only an intake..not nad, compared to most of the guys, from what ive read here, barely noticed anything after their add on..
