to anyone who know anything about engines, my Iroc when timed to the factory setting runs like junk, it is a 6 degree advance(stock), I set it to 8 degrees. It is currently running a 45 degree advance on the ignition and that is where the power seems to be "happy", driving it at 6 degrees feels like a slushbox civic in stock form, it also is very hard to start like this. When I set it to 45 degree advance on the ignition, I pick up engine revs very quickly, burn out in every gear 70mph into 5th and the wheels are still spinning, fifth gear is a .73:1 ratio and the rear end is 3.45 to 1. It has P245/50 VR16's on it, thanks

the car is rated at 230hp @4400 and 300tq @3200. It feels like it is pushin more with the advance have yet to dyno.

also the camaro should idle @ 500, it idles around 1200rpm. it has the L98 cam for 1989 in it. This cam is from the factory. TPI305

way to acknowledge what i said....

anyway, what were all the tuneups youve done so far? do you mean you dial up the dizzy to 45deg when it should be 6? i would be shocked if it was something so great and something must be very off.

most engines make more power as the ignition is advanced because of a fuller burn of the mixture. it probably performs more like it should and before it was subpar. such is the case with older cars

here is everything I have done to the car in completion.

Oil change Mobil 1 5w-30 with a Fram Heavy Duty Filter

Air Filter Change, Spark Plugs Bosch Platinum 4+, Plug Wires

Autolite Pro Series 7mm wires(same as stock), Rebuilt the distributor, with a AC\Delco pickup coil, GP Sorenson Cap and Rotor, KEM Ignition Control Module(there were two versions available i got the more expensive one, it may be for the vette).

Timed the car to 45 degrees, Added fluid and changed the throttlebody gasket. Bosch O2 sensor, Stereo, Cigarette lighter, Floor mats, and a alternator.

i think youve gotten it back up to snuff man. thats how it should be running and as far as the high idle is concerned, i would assume thats alright with the cam your running. again i dont know much about dumestics, but it sounds like youve found what makes the car happy. when i do my next mod for power we should race haha :lol:

yeah sure but at the track that is closer to me. drag strip or circle track? I vote circle track, I have the advantage.

Geschrieben

Circle track? I'd think your car would be a little drag queen Iroc.

Be careful, that little Civic of Bleh's comes in at around 2,100 lbs.(?) and moves like a roller skate. Straights might be your better suit.

close enough. i have done some little things to shed some lbs. (wheels, battery , a/c) so i would say less than 2250 with a full tank and driver.

circle track? is that when you only turn in one direction? :???: boring

come auto-xing with me. june 12 at atco is my next scheduled race day. i would love to see your car take the real hairpins at 50 :).

its $30 for the day. i would definitely be in a higher class, given the motor swap, stiffer spring rates, rear sway bar, and soon to be brake swap. but itll be fun regardless of all that. besides there are plenty of guys in the ss class with you. or would you be bs or as? im not too sure of where the iroc would be placed... i would think ss since its a v8, but i could be wrong

anyway you just take 33south to 78west to 476south to 76east through phili 676east(aka vine street expressway) across into jersey to 70east to 73south which will take you to 30 then you should start seeing signs for atco. 2 hour drive. i actually have a few aquaintances that occasionally come from your area, however they usually go to closer tracks.

http://atcorace.com/ :-))! its not like the normal racing your probably used to, there is competition but it is friendly. people dont worry about the size of their genitalia and arent insecure about how fast their car is.

Straights might be your better suit.
and if i get some r compounds or even azenis by then, you have no idea how true that statement is :o
Geschrieben

my thing was all I needed then was tires and I would win. I dont think your car can go above one 150 so I would have a definite advantage,

Auto-Xing thats when their as multiple cars on a track thats twisty and they are right along side me. I would have to get a notarized waiver. Not 18 yet though it may seem otherwise. As far as the Low end racing I would rock, but only until I break something, probably the tranmission.

Hey bleh the auto-x do you run with others or kind of like a road course. I haven't done the legal racing yet and I dont wanna damage my car.

Bleh would have me no doubt on the 1/4 I only run a low 14 assuming I am tuned in right. But I would still run him. I pull a 0-60 in the high 5's but i die on the high end rpms. The tpi chokes itself to death due to the injectors not being able to fire quick enough and my t-5 wasn't geared for that. Bleh what do you run on the 1/4?

Geschrieben

mid low 15s have been the norm with my setup although i havent taken it to the track since i got the new car and swap. there is no doubt in my mind that you would beat me quartermile, or any kind of straightline racing. i think circle racing is ghey unless your in mud anyway. nascar and the likes bore me.

auto-x = soloII meaning you run alone and are timed for each run. i dont remember signing any waivers or anything like that, its definitely safe. the only way you could damage your car is by intentionally running into something. if you come in way to hot for a turn you still probably wont damage anything except a cone or two. also, i wouldnt worry about breaking the tranny, depending on the track, i doubt, you will get past 2nd gear.

the real deal with auto-x is that its mostly the driver and not so much the car. granted some modifications, especially tires, provide a large advantage. the driver has everything to do with it. that said im confident that auto-x is one of the 2 arenas myself in my car could take you in yours. the other would me miles per gallon or in your case gallons per mile :lol::lol::lol:

Hallo iroc-z89,

 

schau doch mal hier zum Thema Zubehör für US Cars (Anzeige)? Eventuell gibt es dort etwas Passendes.

dude you should go too. see what your piggy can do. june 12 :-))! and if you dont go, can i borrow your helmet?

Geschrieben

yeah i will see if i can make it I have to find out my graduation date, and see if I can get the money if so i'll be there.

Yeah as far as the circle track comment thats what the iroc was designed for. I also remeber reading somewhere that the ram air intake design adds boost N/A style @120mph but i dont know how true that is. Yeah im 17 man i need a notarized waiver form to run, at least on the strip.

a ram air intake will really start to make noticable power at 180mph+ you wont notice any gains under that... and being that most cars dont go 180, ram air = teh svck

Geschrieben

i can pop to 160, but It would take a about 40 secs

Geschrieben

hey nother engine mess up, I was driving it and i couldn't get it above 3000 rpm for more than a second. It would rev to 4500 and then it drop to 3K @wot and it refused to go any higher than 3000rpm.

I let it sit and now its working again i checked fuel pressure and it is where it should be. Any ideas, I thougth it was the fuel pump or the injectors, but my buddy said to take a look at the ecm.

Geschrieben

I take it you have no clue, thanks.

I dont know if I can make it to the auto x, money is beyond tight I dont think i can afford the gas right now

yea i was going to say its going to cost more to drive it to atco and from than it will for the entrance fee. hell the gas you will be burning racing will probably cost more than the entrance fee. :lol::lol::lol:

Engine computer perhaps, but it could very easily be mechanical, like a stuck thingamabob, or a something or other that needs adjusted. The doohickey could also be shot.

About Ram Air, you may or may not notice any effects below 180 ( don't know where that number came from ) but the effects will definitely be there. Better air flow can't help but have benefits all throughout the power band. It's why a Ram Air Firebird is faster and produces greater power than a standard Trans Am, even though neither hit 180+ all that frequently. If you've ever stuck your hand out the window doing 70, you feel the air against your palm for sure. Now imagine that same velocity of air being rammed through a tube to your intake - A conventional airbox can't accomodate that much air flow.

And on the same note, when I was in high school, I designed a home made ram air kit for my best friend's '85 Sunbird. We never built it, but it's fun to see what you can do yourself with readily available parts. I would strongly suggest looking into it for a young guy on a budget. For the Iroc, preferably something none invasive, that routes into the lower fascia.

I hate the rain, yeah just ran 40 miles and burnt off a 1/4 of a tank. Had to take this girl at my job to the hospital, she cut the tip of her finger off on a meat slicer. On the way back doing 70 because of the stupid rain, I put the car completely sideways on I-80 and I lost the back end a few times. Plus not knowing where I was didn't help.

Rain plus road oil equals fun times and scaring the people behind you. :o Redlined it past 7000rpm spinning the wheels so i didn't roll over, shifted twice and and countered steered and i eventually got it into a lane. All this with a ton of cars behind me, I was "leading the pack".

ill ride a crotch rocket daily before i ever think about being in the passenger seat of your car. thats rediculous. i would never ever own an iroc

yeah well, its fun, lots of torque on hand and its a drift car from the factory, did I mention no air bags... Oh and my car with the sliding is a lot better than the old chevelles and camaros they spin out like no tommorrow.

no. i cant believe nobody else picked up on this. its not a drift car, its a burnout/donut car. it spins out. its not balanced enough.
