Sr20det huge problem at wot!

[mat.roberts]

Hey guys im running an s14 sr20 mods are a tome ecru, procams (260/12), fmic, 7psi on a stock s14 t28, car has been running well and great then one day i go to mash the pedal and nothing. Absolutely nothing the revs just start to come down no combustion nothing just the motor dying then i ease off the throttle and its back. I can ease onto the throttle but once i hit full throttle it just dies. So at idle i unplugged the tsp and sure enough at wot she revs all the way up and i plug it back in and it doesn't work. But then all of a sudden on the drive home from work on the highway it all of a sudden works. What could be the cause of this and could it directly be the tsp or possibly something else lmk thanks!!!

Will It Only rev to a certain Rpm freely without bog or will it just not rev at all just like It stops? Check the Ecu for possible codes and check the maf, Maybe try using a differen't Tps if you can.

sounds like this: http://zilvia.net/f/engine-tech/397389-sr20det-falls-its-face-5-5k-rpms.html

typically a boost leak. In this guy's case, a restrictive intake.

Shit I'm gonna change thee intake for sure I bet its that cause I'm running the oem but it is squashed between the intercooler piping.the only thing though Is why would this go away if I remove the tps lol I'll check anyways thanks!

What kind of fuel pump do you have...it could be the fuel pump cutting out too.

replace the tps with a known good one.
