I just put in Vortech but have an intermitten problem
It seems to run ok arround town but i made a bout a 30 mile run in warm weather and shut it down for a coupel hours. When I can back and started it back up i could not get it to rev over 3 grand in gear. A couple people have said they had similar problems one of whom with a supercharged MINI said he solved the proble by going to cooler pliugs.

Would it make that much differnce? Any thought out there on this? What are people out there with superchargers running?

Thanks

 

Denso Iridium IK24 gapped to 0.034".

You should double check all your black box wiring connections. Soldered?

 

Will do but it doesn't really sound like a wiring glitch does it? It sounds more like a heat related/computer problem? Are soldered connections that much more important than good mechanical connections in the wiring? An if so, not to be a skeptic , but what is the logic?

Thanks

 

Time and time again a good mechanical connection causes problems that are solved with soldering.

 

Realtive to the spark plug question???? I aquired the iridum Denso plugs however I have not had time to installed them yet. Last night I was reading over the Vortech manual and it said that when you did the installation if your plugs had over 10,000 miles on hem you need to put a new set in and that they should be the same heat range and specifically not to put in Platinum plugs unless they were the standard plugs for the vehicle. It did not explain why if anyone can enlighten me. It also said to retard the timing but it did not say by how much nor did it say how often you had to change the plugs once in service. All very vauge. First of all I have 23,000 on the car and I'm pretty sure the installer did not put in new plugs or retard the timing however it was running great till I shut it down and came back a couple hours later to start it. Does any of this change the recommendation to go to the cooler iridium plugs??

 

Personally, I'd listen to the two guys that have posted. Also, I spent a ton of time reading through abunch of crap threads to get to a couple of informative ones.

You should not use platinum plugs when boosted. The Denso's that xviper referred to are not platinum; they're iridiums. Copper plugs are also better than platinum but will require frequent changing(approx 3k miles). If you're boosting with the stock Vortech pulley, I'd suggest going xviper's way.

Yes, you do want to run a step colder, lest you want to encourage the potential for detonation. Secondly, it's been 3 weeks since you posted your scenario. Put the doggone plugs in!



Added: Platinum plugs are the ones that don't belong in the kitchen... they can't handle the heat!

 

Thanks for the feedback. Unfortunately the dam job and trying to find some one in Detroit, home of motown muscle and parts, that actually had iridum plugs has kept me on the road and out of pocket so I just was able to score the plugs yesterday and there going into day except that it's raining like hell here so it won't get any road time today.
It does have the stock Vortech pulley supplied with the kit.
Anotherr questions from a naturally aspirated background kind of guy. ( I had a local tuner with a dyno that I intende to have finish off the job but he has disappeared And I can't find another local experienced supercharger guy so I'm going it alone right now so thanks fof the patience ont he dumb questions..

Vortex says to retard the timeng but doesn't say by how much? I have the car set at stock timing and seems to run fine ? Any comment?

 

Also.. what should be the regualr change interval for iridiums under normanl use?

 

You don't have to do anything with the timing. The Vortech "timing box" will do it for you as it needs it.
Also, if you think your plugs were never changed, then it's safe to assume they were never re-gapped to the recommended smaller gap. You need a smaller gap for supercharger duty.

Since this car came with platinum plugs, it is OK to run them if they are not too old. The only thing that's needed is to pull them out and re-gap them. I ran with them for about a year with no problems.

As a side note: I recently had a little issue with my Denso IK-24s. After having them in the car for over a year (daily driver), my engine came up with a slight miss at high rpm, WOT, heavy load (NO CEL). I pulled the plugs out and they looked fine and still gapped correctly. I put my NGK copper racing plugs back in and the car has been running perfectly once again. Not quite sure what to make of this. I was really hoping that the IK24s would be the last plugs I bought for this car. Oh well.

 

Will do
