More like 1300-1400 miles on it now. I have been reading a number of posts on various forums saying these rings could take a few thousand miles to seat properly. Other posts mention idle smoke/blowby because of the seal being so good ?? Oh well. I am not going to pull it apart for another month or two, so perhaps it will settle down with some more use.

 

I would think/expect by that many miles and some WOT useage, that it would be pretty well broken in by now.

 

BTW, what wiring do you have going to the MSD box? If it's not heavy gauge enough I wonder if it could be causing the slew in the box to go up. Just saying.

 

Hey guys,

I bought a bigger boat and have been totally side-tracked by that project for the past month. Drac0nic, wiring to the MSD is not wimpy.. can't remember the gauge but it's the same thing my friend uses on all the turbo cars he builds and it came from him. All connections soldered and goes straight the the battery.

After checking the timing on this boat, which has mercruiser Thunderbolt ignition, I was shocked to see the timing dead locked on to the correct timing. Every time I check my timing on the Iroc it's all over the place by 3-5 degrees. I think this has much to do with my problems.

I'm going to eliminate the Megasquirt this year. I got my hands on a sequential FAST box (but it's older) and then found out the sequential version doesn't have enough outputs to handle fans and the fuel pump. Found a guy who wants the Fast box so I'm going to sell that and the Megasquirt and probably go with a Big Stuff 3. Then I'll have the option of CPS and sequential which won't hurt mileage and might help power a bit.

Today I went to the drag strip to see what 'all this new power' would do. I didn't expect much and the car delivered my expectations. About 1 to 1.5 mph and some improvement on the ET. I have more tire spin in the 60 foot so my best 60 was around 1.96. Taking my previous best 60 of 1.78, the 7.74 I ran today works out to 7.56. With sticky tires and a good 1.55 60 foot it should run 7.3's, so I'm still 4/10ths slower than I should be. That missing 100 rwhp would be very helpful right about now. Car went 7.71 on a 1.6 so I guess it picked up about 1/10th.

Not so impressive for 10 degrees more timing. Torque converter is going back to get re-stalled to a much lower speed. Time will tell.

 

how much u asking for the megasquirt?

 

Stupid question, but have you ditched the MSD and tried using a plain jane HEI module instead? I wouldn't be surprised to find out that the box is a POS especially if it's a 6AL. The later ones they made had a reputation for being very poor quality overall. It could even be a counterfeit depending on where you got it.

 

I can check the spark accuracy without the 6AL but as far as driving it, it blows out the spark around 8 psi on straight HEI.

Not sure on a price for the MS yet but I'd like to sell the wiring harness with it. Will probably be a while before I make a move though.

 

im not in a rush so justshoot me a price when ur ready to sell it

 

ok Project89 will do.

I put up a video of the best pass. I'm not all that disappointed in the numbers right now. The sixty foot was crappy at 1.96 and the car has gone 1.78 these tires (Firestone Wide Oval) so I feel like the car will run high 7.30's on drag radials now assuming a high 1.5x sixty. The mph supports this as well. It's a lot of fun at this horsepower level.

I'll keep working on it. Didn't notice any smoke at all but it is burning some oil as I had to add a bit.

 

Small update. Haven't done much with the Iroc lately but I do drive it a few times here and there. Oil consumption has dropped considerably. Could be seating with all these trips to out of town cruise-ins.

I made a couple of new vids so I figured I'd add them to this thread.

Steve, sorry to hear about your loss buddy, that is very very rough to get through...

 

Thanks Street Lethal.. it was not a fun couple of weeks, that is for sure. Will be a long while before I can talk myself into another dog.

 

Just read through this thread, any new updates? I found your webiste on the original turbo install and plan to duplicate your intercooler mounting/hood latch mods.

 

Haven't done very much lately other than drive to several cruise-ins in the past couple of months that were around 150-200 mile round trips. The car has been super reliable at least. I haven't wanted to put any more money into it lately but right now it really needs tires, subframes, get the converter restalled, a driveshaft loop and new u-joints. All of that is in addition to the new headers and ECM I want to do. Also it was burning some oil so I have to do leakdown testing to see if I have to spend even more money.

I bought a boat in January and that's got my financial attention for now. Otherwise I'd already have this stuff started on the Iroc. Anyway I'm planning to start with the headers. The plans are to start pulling it apart by late June.

Let me know if you need any other pics on the hood latch.
