Still time man, could get it done in a weekend, and that SC will sell very fast. Steve's sounds that way though because he has it setup like a pinwheel lol, once he connects the intake and exhaust to the turbo it will spool slower and quieter. I say go for the turbo though, you'll love it...

Why? Your car runs and drives and is dead reliable.

Joe, and 0:05 seconds into the video, stare at the passenger rear tire area.

They looked like they got blown out of the exhaust...

Wtf..

That's the type of stuff that would happen here. Speaking of which, I gotta go take care of the barn.

Hahaha.. they are my three chicken spider patrol! They come in the shop and turn black widows and other spiders into poop. I think it is a good trade!

Re: Turbo Iroc - Round Four (Edit: Staying Gen1, new PT7675, heads, intake)

i have a question for you turbo guys... how in the heck do you keep the car cool? i'm running stock dual fans and it seems if i don't have both running constantly i can't keep the car cool. the other day i had only 1 running constantly and the car shot up to 240 or so degrees and then the idle was rich/and lean which i assume is heat soak. i let the car sit for 45-60 minutes and the fuel rail temp was around 165 degrees...

i have no room for a bigger radiator aside from going custom due to the outlet hose hitting the supercharger pulley

You should start a new thread, starting with pictures of your engine bay.

I've struggled with heat issues. Air filter placement is a big part of it, and tune.

The car runs best on a tune that creates the most underhood temp. Can't f'n win.

My water temp never goes above about 195, but the radiant temps in my engine bay are insane.

I also have aluminum heads, and big aluminum radiator. Dual spall fans.

I had pulley interference with the upper hose/outlet as well when I had the procharger. When I switched to the vortech I mounted it on the passenger side.

Re: Turbo Iroc - Round Four (Edit: Staying Gen1, new PT7675, heads, intake)

I haven't had any issues outside of the hottest summer days while running the AC. It may have been close to overheating in heavy traffic backup on a hot summer day a time or two. I'm running stock radiator with fans from a Dodge Intrepid. Also I did have more cooling issues when I initially installed the intercooler. I ended up remounting it slanted outward at the bottom. This lets some cool air bypass the intercooler which really helped, but at the cost of about 10-15 degrees IAC. One other thing, I cut a hole in the crash bar between the fog lights. In the summer I remove the fog light trim which opens up that whole area for air flow to the intercooler.

Re: Turbo Iroc - Round Four (Edit: Staying Gen1, new PT7675, heads, intake)

I have been starting the Iroc up for people to hear how the new setup sounds. Yesterday out of the blue it has started backfiring randomly. Going to be fun to figure out what's going on there. I have played around with the tune slightly but I don't think that is the source. This megasquirt is already up to its old self with one start being too rich and the next day too lean. Can't wait to move on from that nonsense.


Ordered on received a new Spohn Pro-Series torque arm
Ordered the supposedly correct front brake lines
Ordered a cobra head intake elbow 4" to 5" along with appropriate 5" conical filter
Received the rest of the charge tube silicone couplers/elbows


Still trying to get this POS Baleigh plasma table working so I can cut out a bracket for the throttle and TV cables. Need to get the throttle cable installed to the pedal. Still looking at a couple of weeks to get it going and that is assuming I can resolve the backfire issue easily.

Well it was lol. Now with the custom cam I've lost alittle drivability. Now going Air to Water IC to free up space in front of the rad. I went from 11.8psi at 5500rpms with the stock motor down to 7.8psi at 5100rpms with the new cam (214/228 .561/.561 115.5+4.5) and ported stock heads. But what kills me is the BOV noise. they are open at idle and under most throttle till right before boost. Sounds like a street sweeper, but Ive found that wrapping filter foam around the BOVs muffles them greatly. Still tuning it but Turbos are so much quieter for 90% of street driving.

You should check out the new FITECH self tuning ECU and harness and its capable with boost. $750 for the harness and PCM without tranny control and $999 with tranny control. Another option vs the MS stuff.

Depends on the setup. If you're running a 160 thermostat, and have your fan(s) set to come on at 190 degrees, and turn off at 170 degrees, and if you are running the proper coolant mix, and you're sure that your lower radiator hose is not collapsing behind an engine load and that you have the proper air dam underneath the radiator, then it more than likely sounds like a timing issue. Start pulling timing in certain areas in the SA Main table to see if that helps. Also, I am running two fans as well, and both are wired to come on and shut off at the same time. One small fan is not enough for the increased horsepower while running the stock sized radiator...

Hmm that is interesting, particularly having transmission control capability. Will keep an eye on that.


Turns out my plugs are completely fouled out from yesterday's ultrarich startup. I don't understand how things could be so radically different between two different days of starting it up. Off with the downpipe so I can change the passenger side plugs. Brand new plugs too! Oh well.

Haha.

I had an IAT sensor go bad the other day and I couldn't even move the car out of the shop.

The air correction functionality is nice, until it leaves you stranded.

So far they are still working. I have a new (to me) radiator and fans to put in some time later this year though.
