Ever since i raced my brother wide open in 5th gear up to about 155 my car has been peaking in 1st and 2nd gear at 17 PSI and runnning at a steady 15 PSI.. has this ever happened to any body else?

before my top end run my car was peaking at about 14 PSI and running about 13 PSI.. almost like the top end run cleaned out my injectors and turbo

i will get some pictures of my boost gauge later today for everybody to see the boost increase

 

is it warmer out now? temperature affects boost levels. this happens a lot this time of year.

 

that must be it.. it is around 80 outside right now.. before it was about 60

what do SRT-4s boost peak at under ideal conditions?

 

yeah but even with the warmer weather isnt 15psi a little high for forst gear stock?

 

Are you completly stock...no stage one or anything...because its like between 90-95 here and I can't get higher than 12PSI spiking in first gear. LOL...go dyno your car while its doing this...you may have the highest HP stock SRT.

 

travis said his car was boosting around like 15-16 psi i think. does the car feel any faster? and is the needle at 0 with the car off? 17 psi in 1st gear must have a lot of wheel hop/spin.

 

15psi is about max that you'll see on the stock ecu, anything higher and you start getting into lean conditions. typically spikes of 16 holding 14 is what most cars see in warmer weather. if you are seeing lower levels then there's probably a leak somewhere.

 

Not to change the subject, but what was your brother driving and who won?

 

my brother was driving an 04' mach 1 mustang with intake exhaust and a power programmer.. i beat him in top end.. just got to the front of his bumper by 150.. i started a couple feet behind him so i gained a little over a full car length on him by the time we hit 150


well.. an update on my car.. in 4th gear it is now peaking out the boost gauge.. past the 20 PSI marker.. i stopped flooring it in 4th because i know my stock SRT-4 should not be reaching 20+ PSI.. I am getting pics and i will post them for all to see tonigh.. i think something is wrong with it..

in 1st gear i peak around 13-14 PSI.. 2nd gear it will peak at around 16-17 PSI 3rd drops down to 14-15 PSI for some reason then 4th it goes off the boost guage

does this ever happen if something is going wrong with the car? Its starting to worry me..

i bought 215s for my car so now all i get is bad wheel hop in 1st and a small spin in 2nd if i short shift that lasts less then a second then the tires grab the road

 

is it spiking over 20 when you floor it from low rpms in 4th or when you're running through the gears?
