rynberg - I noticed you are running Earls coolers...upon searching oil cooler set-ups, I found a statement that noted, you should not mount the coolers by the ears, Earls has some money making brakets/tension rod kits they sell. Just a thought...it appears that your ears are bent, is that the due to mounting or the "snag"?

got any pics with you bumper on?

Yeah, it's not a berm type sensation at all (I KNOW what that feels like, LOL). It's happened on several different road surfaces, so it's not uneven traction.

Will do, thanks. I still have the heat-blasted originals.

Hmm...mine were/are mounted by the ears. No problems after 2 years of hard running. The mounting DOES bend the ears slightly. Perhaps I oversnugged on them, but I think that's the nature of the beast. I was slightly more careful putting the new coolers on.

No finished pics...but I'll be posting a bunch of pics of several different projects pretty soon. There's really not much to see....the entire openings are filled with silver cooling rows... The RE kit mounts the coolers very close to the bumper openings (unlike the CWC kit).


Oh and BTW, finally got a break in the rain and took the red beast out Sat night....from a roll on in first, no traction after 3500 rpm, shift into 2nd, tires start spinning after transition until redline shift into 3rd, at which point the tires finally hook-up, cocking the entire car sideways. Haha, good clean fun! I need better tires....(265/35 Toyo T1-S).

Wow... you're making some serious power! My 245/45-16 Toyo T1-R tires have no problem keeping traction with my mostly stock engine.

Put some R compounds on it and take it to the track!

that's what I thought, due to the "dirty" spots on your old coolers. Does that size cooler allow you to run the oil cooler undertrays? Are you monitoring oil temp? Last question, I promise...can you give me an idea of your air intake temps vs ambient (15psi, correct?)

sounds like one hell of a ride!! I can remember the days of seq and having the rear start to kick out as soon as I floored it...then kick out the other way after the transistion.

anyone interested can get some good info from here:
http://www.stoptech.com/tech_info/wp_knockback.shtml

if one of your wheel bearings is more loose or worn than the others, you can get more pad knock on one side than the other. this could certainly cause it to jerk while braking.


try this: drive in a straight line and hit the brakes a couple times... does the pulling lessen after pressing the brakes a few times?

now go make some turns--doesn't have to be a canyon run, but maybe scrub the tires nascar style a bit, then hit the brakes. does it jerk more the first time the brakes are applied?

Yes, I'm running the cooler undertrays, although it's a TIGHT fit. My oil temps with the dual coolers run about 40F cooler than with the single stock cooler. During these "winter" months, the oil temp is damn near TOO cold.

I haven't been running this new tune at 15 psi long enough to get much AIT data. The other night it was about 50F out, I would guess, and my intake temps were in the low 40s C after some boosting, pretty much in the high 20s-low 30s C otherwise.

Thanks a lot for the info, I will be trying that.
