is it cutout on my Jaytona?

[Bowza]

yo..now that i got my cat removed and a straight threw muffler on my tona...when i slam it to the floor..it gets up to high rpms and it cuts out for a sec..then goes again..i got the 2.5 l and i thought my boost was only suppos to go to 8 psi and a bit of overboost or something..but now my boost goes all teh way up to 12.5/13 ...do you think it is my computer not allowing it to go past the boost limiter?..so it cuts my boost out for a sec..or is it something else...

and could someone plz tell me what happens when detonation occurs..i heard all bout it..duno exactly WHAT it does/is...thx guys..

detonation is a *bang bang* sound that means you are killing your engine. to simplify:

DETONATION = DEATH

also, i wouldn't talk too much about removing your cat, considering that is very illegal. i would, if i were you, look into getting a high-flow cat. if you get stopped for a roadside spot check, and are sans-cat, then you are totally screwed- that's an expensive fine, AND a repair ticket.

just a suggestion

Don't worry about the cat, I've NEVER been inspected. EVER. It sounds like what's happening is your hittng max boost and after the pre-set time limit it's being reduced to lower cylinder temps for a few seconds.Which will help to prevent detonation. I think it's until you let off the gas a bit. It's all normal stuff your logic module is taking care of. As long as you're at WOT the timer doesn't count down to allow "full" boost again though. There are ways of tricking the map sensor to only "see" the 8psi but still run 14-15 all the time but if you don't have the fuel system to compensate for it don't even think about it! The margin for error is very small when tricking components that normally work in harmony with each other.

Ok,
What did you do with the O2 sensor?
I didn't think you did anything. now change it.
Remove the air temp sensor in the intake and replace it with a 100K resistor.
Check your TPS too, along with almost all of the other sensors.
be damn sure your intake air hoses are sealed tightly and that they dont swell or collapse. I recommend replacing then with pipes, but the stupid rubber hoses will work.

You NEED more fuel volume and a reprogrammer kit....!!! Or, drum up an old Direct connection turbo II computer from Carrol Shelby...

Detonation is bad, but fortunately, you don't have a Civic (not fond'a honda) or an eclipse ( e-clips?!! either way you're shafted!!). Never seen a 2.2 or 2.5 die from detonation. I have seen an eclipse die from daytonation (being wasted by a daytona... mine!).

Enough fun for one post...

LOL dunno about that resistor though, won't it make him run a little more lean? Good for HP bad for detonation... Yeah I ran tons of boost with a secondary 5th injector right on the limit of the green lights and never had a problem with detonation either. The mains ended up giving in first. That and the hydraulic adjusters couldn't keep up.

hunh, didn't know that... never got around to FI on any of my dodges so i never had to worry about detonation

whassa mattah slant, been whupped by too many small-displacement H bombs? i love my car, i'll probably drive it to death several times over. i like my dodges too, and even my old ford crap-wagon has some fun parts. no reason to go hatin' on something that beat you just because you can...

after all, bet you don't mock that 'vette that just passed your ass like you're standing still

[Bowza]

hmmm...ok..so my problem doesnt sound like detonation cause my engine aint makin a bang bang..so im guessing it would be my map sensor doing its job. a 3 bar map sensor will eliminate this correct...would a stage 2 calibration from fwdperf. eliminate the problem as well?..i plan on gettin an intercooler before turning boost up to 14 or so thou..so...yea

[Bowza]

and do you figure my turbo gage is reading wrong when i reach 12.5 psi when i should only be reading 8 or so?..when i got a flow threw exhaust it seemed to have turned up a bit..oh yea..and you were talkin about my cat stuff..not that it would help me if i got pulled over and inspected, but i got flanges on all my pipes so i can remove straight pipe and put on my original cat pretty simple..im off to school..lata

Geeko-

I don't race anymore, certainly not on the street. The point was it's rare to have a 2.2 or 2.5 die from detonation.
You like what you like: I like what I like.
What I like is just faster.

And I've never been passed by a 'vette like I was standing still, unless I WAS standing still.

I'm not in the racing scene/gang/group anymore. I have a wife, daughter and a life, that keeps me from that waste of money. There was a time when I would dispute that to the end of the 1/4, but not anymore. I want to be around for another 40 years... or longer.

My 2.2 has seen a couple headgaskets but it's otherwise bulletproof. I don't believe you can kill these 4 cylinder Chrysler motors...

[slantsixness]

As a 2.2/2.5L thread this has become, I've had lots of them. Good motors, BAD carburetors. Fuel injection works well. MPF injection is really good. Turbo version aren't bulletproof, they suffer from chryslers "Turbobyebyetis", where the turbine comes unglued and sends all your oil into your intake, but that can be dealt with if you know when to shut the motor down! (like the moment the white smoke comes out... )
Use intercoolers and VNT's or aftermarket turbos and WOW!

I had an '87 shelby Charger,'90 daytona ES 3.0L, '90 Daytona ES 2.5L (VNT, intercooled and NOT factory), '79 TC3 (originally a VW 1.8L until the 2.2 turbo drivetrain), a Lebaron GTC, about six K-cars, an Omni 4dr (pre GLHS), and two turbo 2.2 Caravns (one was a 5 speed manual!) These were daily driver cars except the shelby and the '90 daytona. Unfortunately all but the second '90 daytona (the VNT) are gone down the road, and my father in law has the daytona now (his GM car died, kind of funny-he had his mid-life crisis and ended up with his son-in-law's last non-family sedan ride!). I'm looking to maybe squish a 3.5L mitsu motor and two VNT turbos (it will fit...)in another Daytona when my wife let's go of my arm...and some dough!

hey, i'm in agreement- i'm on the front of the hill going up, and don't want to spend the rest of my life in a wheelchair, or worse.
*shrug* i'm probably overreacting- just sick of people either making fun because i've got a honda and it doesn't have a bunch of body kits and crap, or people making fun because i drive a honda and want to increase its performance. i don't race- at all right now, probably not much if i ever do- and not on the road. i like to drive- and i drive hard. i like it when my car reacts to my desires- a complete melding of man and machine (cliché, i know, but true) brings me happiness.
all in all, that's what matters- that you are happy with your ride, and enjoy driving. so run some FI on that teeeeny honda moter, or rev up all 454 cubic inches of that monster under the hood of your charger!

~cheers~

[DaYtOnAt2]

I thought a 454 was a bowtie motor...I get the point though, and agree...

[Geeko]

craap... can't believe i did that, my buddy would kill me >.<

okay, the 454 under the Camero hood.

my dream car is a '69 Supersport, cherry red, black ragtop, with a freshly rebuilt 454 under the hood i'm a long way away from that with my civic... but who wants to daily drive a 454 with gas at 2 bucks a gallon?

[slantsixness]

I'm an A-body (dart/duster/swinger) man. Although I've had some B-bodies (charger/GTX/Roadrunner etc) but they didn't do as much "warm fuzzy feelings" as a 12 second A-body. Plus, the A-bodies are easier to park...!
I originally bought into the fact that the Later charger and daytona's were going to give me that "warm Fuzzy feeling" back, but I had a lot to learn about the 2.2 and 2.5 and even a little about the 3.0(dog). So, in the efforts to make one of these newer FWD cars scream, I've wasted 10 to 15 times the amount of money it costs to make a 12 second (ok, 12.49 @ 104mph.. still call it a 12!) street legal car. I was able to beat the average Z28/iroc camaro's and 5.0 mustang's with the FWD cars, which did give me a warm fuzzy, but I have always been disappoointed with the lack of real recognition the FWD cars get, and even the "muscle car" mopar freaks don't give the FWD cars the recognition they deserve.

Sadly, the most interesting thing coming out of the pentastar-benz company now, is either way overpriced (viper), or way underpowered (ptcruiser convertible 2 door).

I'm lucky my wife let's me keep what I have. And she has a camry (although it is a V6....) Her first choice was a honda Accord.....!
So, I'm not immune to working on, and liking the ricers either, but I still don't think they'll ever give me the warm fuzzy's!!

too much time on the soap box!

Later,
