Installed Intake and now boost kicks in later
is his suppose to happen? i mean the stock boost kicked in around 4.5k rpm and i bought an intake from ebay.. came with filters... i intalled it and now the boost kicks in around 5k rpms... i mean the car is almost bone stock all it has is a 3inc exhust and a down pipe.. it still has the air pump for the emissions but i put a mini filter for that as well untill i get the air pump out of there... any help please i hate my boost kicking in at around 5k rpms

make sure their are no leaks. if it came with the rubber couplers then tighten them alot.
|
Do you have a boost gauge? If you don't you need one to diagnose this. If you do, what is your boost pattern?
It sounds from your description :Wconfused that you are not getting (and never were getting) primary boost. A delay of the secondary (post-transition) from 4500 to 5000 may be just a vacuum or pressure hose loose, but other things may be wrong too. There are boost-troubleshooting links in the stickies. |
ya, get a boost guage. If you are putting out around 3-5psi you have a boost leak. Check your crossover pipe. Rev the car and listen for air comming from it. If their is, take it off and put water in it to make sure their is a leak and where its at. There are several different places to where you might have a boost leak.
|
Make sure you didn't disturb any of the small vacuum hoses on the y-pipe, particularly the ones going the the charge control actuator. (That's the golf ball-sized one)

http://i9.photobucket.com/albums/a54...X/DSCN1647.jpg dont mind the string i was exparimenting with something |
you need to do somethin about the open hoses u have
|
About the hoses, you can put on a chair leg cap and drill some holes in it like daleclark did. You can vent your stock BOV. What i would do is take off all that yellow that is goin on under the hood. Looks very rice. IDK, maybe its just me. Get some K&N filters instead of those that came with the harpipes.
|
jesus, whats all that yellow shit? and yah, u might wanna take care of those hoses.

ok 2 things..... yes i need to do something about thos loose pipes.. donno what yeat... second the yellow things came with the car and i dont mind them.. dont bother me and thats all that matters..... and i guess 2morrow i will just make a video of me driving inside the car ill do the rpms and then the boost... so maybe that can get u guys a better example
|
1st-you can vent your stock BOV, put a chair peg with some holes drilled in it on the air pump hose, and idk about the other one. 2nd-Please for the sake of RX-7 take those yellow wire protectors off and bury them far from your car.
|
ok whell im not really doing anything about the yellow since it dont bother me..... but im going to bed for now and if 2morrow u can better explain the drilling of the holes and blugging the stock BOV.. and whats that one tube thats to the right of the top intake i mean whats that for??? it makes the car have a weird noise as its reving up.....
|
I think your talkin about your airpump. Well if you want to be efficient just buy the TKT intake syste from pettit. It hooks up all these hoses separate from the 2 main intakes. It also provides K&N filters for your crappy ones you got there.
|
is the noise comin form the airpump normal, cuz mine is doin the same thing after installin a new intake, i put on the apex'i one though
|
ok whell finnaly i got a video (shitty) of the boost.. it will be up in 5 mins... lots of shaking cuz i had to have my bro lean over and record it on my digi cam.. since i dont have 3 hands
|
Why do we need a video?....lol
Just post what boost you are getting at 3k rpm, 4k rpm etc. |
If you have trouble posting it, I can host it on my website.

humm was having trouble on putfile so i went to youtube its says processing so in a couple of mins i should have it up... it seems that my boost isnt constant.. kinda looks like its jumping around.. i will post 2 vids i guess one of the rpms and then boost.. they are both starting from second gear
|
any freaken day now.....
|
If your going to get rid of the air pump any way just unplug the electrical connection and plug those hoses, the ACV (factory BOV) and CRV (charge relief valve) and vent to atmosphere (unless you don't want to hear them then you can stick the little filter on the ends like the one you stuck on the air pump hose. All those hoses went to th air box for noise reduction with the exception of the air pump intake hose which went there to keep the air that entered it clean. I not sure I understand how putting on the hard pipes could affect you primary boost unless it was already a problem before the change. My boost actually increased by 1 Lb. on both pri. and sec.
