Very upset, dyno results Options

[StreetRacing10PS...]

ok, so i took my 7afTe to get dynoed today and was VERY unhappy with the results. at 8PSI it pulled a 93.5HP and 97.7Ft-lbs torque. thats less then stock!!! i have no clue what is wrong with my car. its def getting boost too because from 3-5 k u can feel it pull and then letting off the gas the BOV goes off. so i Have no clue what is wrong. if u have any idea whats goin on let me know. right now iam goin out to look at SRT-4s cuz i want a second car, this car just aint doin it for me.

u just made me not want to turbo my car, iknew the turbo would end up doing sh!t ne way on a 7afe

[presure2]

sounds like you have a MAJOR problem, like a boost leak, or somthing.

[dustin15brown]

Yeah something isn't right.... You should go and re-check everything

THERE IS NO WAY YOU SHOULD BE MAKING THAT LITTLE POWER ON 8 LBS

ok first check all connectors then check the pipe right below the turbo it has a little metal nipple make sure there is a rubber cap on it.

i just dont understand something is wrong i dyno tested that hole kit kit 3 times and 3 runs each time take detailed pictures of everything also check to make sure all the bolts on the turbo housing are tight

edit: those numbers should be your stock whp almost seems like a pipe might be loose between the intercooler to the TB or a massive boost leak recheck the everything from manifold bolts to vacum line connection

can you put up the DYNO chart so i can look at it

I mean at only 4.5 psi i made 126.95 whp and 162.03 torque

No, a turbo would work on a 7afe. As long as it's installed right it will work.

He's just having a difficulty, but I'm sure he''l find the problem soon then it will be awesome!

Yea i have verison Pm me for the # if u want, but i think i found out the problem. i took out my spark plug wires and the 1st and 2nd 1's are completly shot. these wires are new too and cost me $130.00. i took them out and they completly fell abart into 4 pieces. thats probly the problem cuz if it was runnin on 2 pistons then 1/2 the power would only b around 90HP any way. iam goin to go out now and buy new stock wires for now and see if thats the problem.

my girls got verison but anyways did those new wires fix your problem?

[Batman722]

note, the MR2 very high HP guys will tell you "always use OEM Toyota plug wires"

no jive

[StreetRacing10PS...]

i replaced the wires and brought it to the track and at 8psi ran a pathetic 17.770 so the car seems like it is still around 90 HP

Edit: my second run was a 22.8 cuz my car wouldnt shift into 3rd gear on the automatic and it started to miss fire. ended up that a spark plug wire was loose but the car still seems the same. i even cloged the hole one the IC piping. Still have no clue whats goin on

Do you have a kit from Nik? Is it the same that hes got? I'd just check everything one by one. fuel problem, intake clog, exhaust restriction.

[BBoYRuGGeD]

hmmm very strange... i hope u find the problem asap. like nik said... the 7afe has potential when a turbo is slapped on it, its just that theres prolly something going on that u havent come across yet. anyway goodluck!

bboy

[Hanyo]

another auto 7afte, how is the tranny holding up, and why would it not shift.

Post your air fuel mixture chart for us, maybe its leaning out?

i set up the safc2 to runn a little more rich and still no change. iam goin to take apart the IC piping make sure nuttins wrong, set the boost a lil higher buy a new boost guage and see what happens.

MWAHAHAHAHAHAHHA i'm faster with my N.A manual 7afe

[StreetRacing10PS...]

i eliminated all the problems and the only thing it could b is the waste gate. other then that everything is fine. my boost quage is still reading 15lbs vacume at idle and 0lbs boost at full throttle.

if your only reading 15inmg then you have a vac leak
it should be 18-22inhg.

i thought you said it was at 8psi in your 1st post?

[StreetRacing10PS...]

were the waste gate is it should b at 8lbs. with the wastegate were its at it pulled off a 93hp on the dyno, with the waste gate open it allmost seems like it barley moves

[boosted_K2]

if you are having engine problems and something is wrong.... the absolute stupidest thing you can ever do is add MORE boost...

[right][snapback]335701[/snapback][/right]

add a manual boost controller i never ran that setup off the waste gate you can but to be safe get a controller and start and 4 psi check the boost gauge and hook up your lines like this

edit:

ok sorry that i wasnt detailed about it but here i'll break it down a little

map sensor line ( dont split off)



FMU or boost controllers ( the first black T is for my FMU and the second T white is for my greddy Profec E-01)



boost gauge and or bov (the line coming up over the TB is off the big line in the middle back of the manifold) look close



here a close up



all these pics are in the how to but i just need to rewrite the how to to be more detailed hope this helps

get one of these manual boost controllers.If you have checked all the connections and everything is tight and the hole is caped off its got to be the wastegate so get on ebay or borrow one from a friend.And keep me up dated

[soltrain]

damn, nik's got some good advice

[95CelicaST]

and some good money! I want a turbo! Nik, sell me your 7A-GTE engine.. and then install it...

I have 4 times the money into my 7agte than i did on my 7afte but i learned alot on my 7afte project and even more on my 7agte project

you'll want this motor even more when you see the numbers it puts down

edit: any update street?

[StreetRacing10PS...]

found out the problem was my wastegate. i put a clamp on the vacume line to the waste gate and now am boosting at a whoppin 3PSI!! lol all i need i think is a manual boost controller and ill b set.

[dustin15brown]

good to hear you got it fixed man

[StreetRacing10PS...]

now the only problem is the intercooler piping. the clamps keep comming loose from the boost and the rubber piece that connects the turbo to the 1st part of the intercooler piping keeps coming off and its a pain in the A$$ to get to.

[right][snapback]338053[/snapback][/right]

i had that problem 'til i replaced all my clamps with the super dedooper heavy duty plumbing clamps from home depot. freakin' things are super strong!!! no probs boosting to 9psi now. the ones found on ebay are weak as hell thats why my old ones kept coming loose whenever i boosted.

bboy

[presure2]

i recommend some good T-bolt clamps from a reputable source like hightempsilicone.com or turbohoses.com or one of them places.
ive been using those since i started my turbo project, and havent had one loose connection yet!

[BBoYRuGGeD]

yah im eventually gunna go with the tbolts myself when i start boosting higher

bboy

[lagos]

its not really a matter of how much boost you run. my cheap clamps let go on me in the middle of the highway, last year. i had to pull over, and try to couple them together right next to a hot downpipe with limited space to work...not fun. get the tbolts as soon as u can. ive had mine for over a year and they never let go.

[playr158]

yea i was driving an srt4 and a clamp wasn't tight....not fun to be pushing 20psi and all of a sudden a big pop comes out

[right][snapback]338053[/snapback][/right]

the one right below the turbo is a pain to get but once you do clamp it tight on one of the 14 psi runs i blew the bottom pipe apart i just got in there clamped it down real tight and never had a problem again atleast you finally got some boost though now like i've told you a few hundred times already recheck all connection and make sure there tight and have fun boosting and get her redynoed

ok, so i tightened ALL the clamps with a wrench instead of a screw driver and they arnt coming off. i found out the problem with the waste gate. because it was all ways ran off a manual controller the waste gate was jammed with dirt and stuff so i cleaned it up and sprayed some WD 40 in theirand it works fine. i bought a new boost guage cuz i broke the old 1 and when i hit 5 PSI and let off a TON!! of white smoke comes out. 4PSI nuttin... but at 5+ PSI i dn whats goin on. i have around 86K on my car but if u think about it for a 10year old car thats not much so i dn whats goin on. any suggestions??

[Dr_Tweak]

You saw a ton of white smoke is coming out? Hmmm... white = water... possible head gasket?

Thats what i thought but usually when u blow a head gasket ur oil comes out all creamy and looks tan. i checked my oil and its not that so head gasket might b out of the question. iam not sure tho so iam goin to buy a metal gasket and see if that works.

there is alot of work invalved in replacing a head gasket if you do it yourself make marks on your timing belt and gears so you can reinstall everything correct

Edit: if you have a chilton book this is a good time to use it and make sure you buy a good headgasket

I have done head gaskets b for. i did 1 on a 4afe corolla so its probly goin to b the same. my local parts store carries a metal head gasket for the 7afe so i think iam goin to go with that.

[celicast3sgte]

what condition is your turbo in? make sure it is in good condition and a metal HG will be a good idea anyways.

[right][snapback]338846[/snapback][/right]

The turbo is in perfect shape because i got it fully rebuilt and port n polished less then a month ago. i drove it around to day and in the morning it was smokin like crazy but after a while it stoped and hasnt smoked in hours. only a lil bit of smoke is coming out from under the turbo now so iama go take a look at that n change my oil real quick too.

[Dr_Tweak]

Also, a blown head gasket can have a variety of symptoms, including: water leaking into the combustion chamber (sounds like you have this which is why it kind of goes away after a while and is worst when you first start it up), air leaking into the coolant, air leaking into your oil, oil leaking into your coolant, coolant leaking into your oil, oil leaking out of the engine (external head gasket leak), water leaking out of the engine (ditto), and oil leaking into the combustion chamber. You could have just one or more of those symptoms.
