I have everything to do a boost leak test but no air compressor.....

BTW do you still have the stock clamps on the car? if so dont waste your time doing a boost leak test, because I can tell you that you have leaks.

What kind of boost troubles are you having?? normally with a leak unless its super bad wont effect boost. Dave had a horrible leak that we found and his boost was always solid, usually your afr going rich is a sign you have a leak....Thats always my first clue, but other issues can arise as well.....thats why im wondering what your actual problem is?

 

i have the apex'i avcr.

i hit my target boost ~23psi and it holds till about 4 grand. then it drops off suddenly to ~14psi and bounces from that to peak till around 55-6 grand then holds around 18psi to redline.

it does it when i do long gear pulls, but if i start in first gear it won't do it.

 

and yes i have the stock clamps

 

You need to install t-bolt clamps, stock clamps are junk....you cant tighten them enough, t-bolts you can crank down until your red in the face

Im not a fan of those electronic boost controllers, I think they create more of a headache than they actually help....which sounds to me is the problem.

I would say do t-bolts and boost leak test first, see if thats what it is (which im doubting but might as well do it and check that off your list) then if it still doesnt go away swap in an mbc and see what happens. You just have to go through trial and error at this point, unless there is a setting you may have bumped or someone changed?

BUT ditch the stock clamps, they are hurting worse than helping

 

I would pay someone $100 to replace my stock clamps with t-bolts instead of doing it myself next time. Damm PITA!

 

thanks trav that's what i'm going to end up doing here soon. But the EBC worked great in my honda and worked great when i first put it in the evo. the past month or so it started acting up

i had the solenoid tapped into the BOV line so i thought maybe the BOV started to leak and it was messing with the controller.

the other day i un t'd all the lines and hooked my vacuum manifold up off the break booster line so everything had it's own vacuum line. and it still does it.


i hate cars haha

 

Should have called me, I would have done it for $100.00 no problem

 

Just tap back into your bov line because that wasnt causing your problem, even if the bov was leaking.

You should just throw a mbc in and I bet the problem goes away....you can get a joe p. mbc like I have for $45 and it works like a charm and its ugly (goes well with the cardboard heat shield ).

But def. get t-bolts in that car and crank them down

FTW

 

Here is a T-shirt for you guys.

 

hahaha i'm selling the AVC-R it's still giving me problems. i've had it for 3+ years and never gave me issues on the external wastegate. it just seems to hate the internal gate.

if you know anyone that wants one or an evo ix field harness let me know. i'll let them go cheap for locals.


and i want that shirt!

 

Thats the spirit.....

 

Don't tighten T-bolts too much or your in for trouble. THey will crush things. Really if you want to, you can use silicon under all the clamps and you will have no issues. The stock clamps can and will work just fine unless your running some insane boost. T-bolts are better but i wouldnt say required.

 

I tighten my t-bolts down until I cant tighten them anymore and i have 0 issues....and I have used t-bolts for 5 years now on 3 different turbo cars and I trust them more than anything out there. I gained a full point afr going from tightened stock clamps to tightened t-bolts, so that tells me I had boost leaks eventhough my clamps were all tight and I gained lost power from it. I boost leak tested mine up to 30 psi and the pipes didnt blow or leak, so if they arent leaking at 30....They wont leak at 25 psi

Loosen the stock worm clamps once you never get the same clamping force as they were from the factory.....T-bolts you can tighten and re-tighetn some more and you never lose that clamping force. I would rather spend $60 for the peace of mind then have to mess with silicone everytime you have to pull you charge pipes off, but thats just me......

 

today is the day i turn 23 Hopefully my slowboy santa has all my parts in for me so i can get excited. and BTW, thanks for remembering guys

 

The older you get the more you wont care its your birthday....I turn 27 (30 is coming!) the 15th, and I could careless

but to turn 21 again.....now that was fun

btw happy birthday.
