Does anyone have any suggestions on stage1 or 2 mods that works well in high altitude? I am in Colorado Springs and am trying to take times below 13.0s. Most runs I have seen have been running around low 14 stock on the track.

 

The turbo should compensate for some of the loss at high altitude...

 

how about a bigger intercooler? you have a bigger surface to capture the air that way...

 

I have this same problem. I cannot get my car to break 14.1's or get anything over 95 mph at the track what so ever. The worst is the lower altitude I go the slower the car gets which works completely opposite of howcars should be.

 

i'm in colorado springs also! what color is yours? i put on a 3" cat back, HKS downpipe and K&N panel filter, helped out a lot in the upper RPMs, that's for sure! it doesn't fall off near as much above 5500 anymore and it boosts about 300-400 RPMs sooner. i used a magnaflow muffler and had Buds muffler custom make a 3" cat back with mandrel bends, in case you were wondering, very low and quiett tone to it, sounds sweet! definately worth it fo rthe downpipe also.

 

It made a hugh improvement on his evo when he did these mods. Can't wait to do mine. JA3A you should look one of us up we are both in Colorado Springs. Go check out coloradoracing.net you might like that site. Late
