dammm the ka-t

first test drive today, the damm car wont go past 2psi.. it takes a very long time to make 2psi to like 4k in 1st. it also feels like its hesitating around 5k but then i leaned it out to 10.8 and if took me to 6500.

also my bov doesnt open, wtf is wrong with my car? is it running to rich , i know its suppose to be 11.7, i checked for leaks i found one and fixed it, and still the same problem, also i re titned all my couplers. so why cant i make more then 2psi wtf?

think the turbo is going bad? i pulled of my maf pipe and checked for play or free wheeling but no result?

im running open downpipe will this matter i dont thing so tho... my head hurts and i hope my turbo isnt blown

please ka-t tech help!!!

So this is the first time you have tried to run your Ka-T setup?

It sounds like your wastegate is stuck open, or maybe your boost controller is messed up. Are you internally or externally gated? Have you checked to make sure you have a good vac source to your WG?

If you dont have any shaft play, the turbo spins freely, and your blades arnt toasted, your turbo shouldnt be the reason your not getting any boost. Your DP being open has nothing to do with it, if anything that helps the turbo breathe.

Also, with the DP being open there is a chance that you couldnt hear a pre-turbo exhaust leak. Start the car and put your hand near the headers and the turbo flange to see if you feel anything.

found the problem, wastegate stuck open?

does anyone have some insite on why? what vacume feed am i suppose to use? the one on the top chrome cap? or the one toward the lower end?

btw im using a turbonetics evo wastegate

So your running an external WG? On the Tial WG you are supposed to use the SIDE port for the vac. source and leave the top port open. The top port is only used if you are running an electric boost controller. Hope that solves your problems.

yea im using a turbonetics external gate.

i disconnected the vacume feed from the wastegate and pluged it up. and it still stayes open..

any ideas?

[wild_maxx]

you are using at least one of the ports correct? (the side port)

You can pull the WG off and make sure the firering is seated correctly. (the metal ring what sits inside the bottom of the WG and the flange) If your WG has that.
