If your like me, and are on a VERY tight buget but still have the need for speed, iam sure you'd love some free HP. i still got a front end to fix :banghead:
And since my throttle idea was a bust, i've been thinking about other free, or VERY cheap mods to get more power. Any ideas?

Cheapest mods that actually give you some power are:
1. Free-flowing Cold-Air Intake
2. Free-flowing exhaust
3. Performance chip/PCM re-flash
4. Complete tune-up

Read 4.9 performance, we mentioned a few cheapies.

iam gona go get some new spark plugs tomarrow, whats the best ones? oh and i dont have my manual, so what do i gap them at?

If I got it right, you'd gap it at .060
Bosch Platniums are nice....

Platinum is old news guys. It lasts awhile but isn't a very good conductor. Iridium is the latest "hot-ticket". It'll outlast AND out-perform platinum by far. The only manufacturer I know that makes them is Denso. Check it out here:

Denso Iridium seems to be the trend, but I have a friend who mines hardrock, and he says platinum is HARDER than Iridium. For a car application, I'll take Bosche.

The point is NOT how HARD it is. The point is that it will last as long as the platinum in this application AND out-perform it in the ignition system because it's a better conductor than platinum.

Actually he thought that platinum would be a better conductor, I don't just buy a product because of the advertisements for it, I buy it from my personal experience, but yea, I would try the Denso's, but I will wait until they are proven a little more in history.

I have a few highflow cats for a deville in my shop. Brand new Carsound brand, claims 8-10 hp gains. $160 shipped to US 48 if youre interested, mbanks21@yahoo.com

I know this is reviving an old thread, but....

On the Platinum vs Iridium vs std plugs debate, some comments.

1. I have run a few sets of Bosch Platinums. I have had reliability problems with the platinum wire "dissappearing" from the insulator. No way to know if it fell out and got munched, or burned up. (91 Bonneville 3800, 1 wicked iginition system from the factory....)

2. Champions, suck. I have used 2 sets in my lifetime, and both had 1 plug out 8 fail. Flat out no conductivity anymore. Dead plug. Forget em.

3. Autolite and AC Delco are the only plugs used in serious turbocharger applications. Why? Durability. They can stand up to boost and survive. Problems with them? None. Typically last 50K miles on std plugs.

What I like about the BPlats and Iridiums, fine wire concept. It has a small area, so when the high voltage builds up, there is a much higher potential for spark under harsh conditions. So under heavy load and low rpm, the potential for missfires is less. Thereby more power and lower emissions.

Personally, I stay with the AC Delco or Autolites, as reliability is excellent. The best being the Autolight double platinums. My 1996 Suburban with 191K miles just got the FACTORY spark plugs removed. Best I can tell, they were rough, but alive. Autolite went in to replace. Runs better, smoother, and mileage is up a little.

So, that is my humble opinion.

Iritidiums if they can survive would be a good plug..... Bosch Plus 2's have a lot of potential too. I like side gapping my plugs in my 80 T/A.....

i think that i found a site on the ac-delco webpage that said that they are either coming out with or already have iridium plugs for most applications.found it http://www.acdelco.com/html/pi_plugs_irid_main.htm

How about gutting the interior and removing the bumpers?

^^^ to bad these arent Saturns....we could just tear off all the body panels.

I'll look at the iridiums when I change the plugs/wires on my 92 Deville. It will need them soon. Thanks for the advice!

i run an MSD ignition with ac-delco rapid fire plugs. i wonder if the iridiums will be better for the ignition?

I aquired my first Cadi just last month, '89 Sedan Deville, 75,000 miles, 4.5 TBI, etc. I drove it before I bought it from my friend and almost passed on it. I tuned it prior to buying and was very pleased with the results. Before the tune-up I would have run my '96 Ford Aerostar 4.0 V6 against it and would probably have won. After the tune, the Cadi purrs and gets out of it's own way at least. For plugs I used your basic Autolites, #605 at .060 gap. I wonder if I would see an improvement with platnum plugs? I can tell you that I have since replaced the air filter with a K&N hoping for improved performance and mileage, but have yet to see a noticeable difference. I suspect I would have to open up the exhaust a bit to allow better breathing. 'Twice-pipes' with a nice low throaty rumble would certainly sound good at least!
ANYway! A good clean tune-up is un-doubtably the place to start. After that, I am open to suggestions as well.
Thanks,
Kev

Anyone take a look at the Bosch Platinum Plus 2's? Forget the Plus 4's, the shroud the spark too much, but the Plus 2's look to be the best compared to side gapping (which is about best you can do for spark exposure to the fuel).

Tom

i stay with ac-delco rapid fire plugs. when i had bosch +4's, throttle response was sluggish. i took them back for being unsatisfied. no problems.

i have been thinking to switching to iradiums because of my ignition setup, but im not too sure if it is worth the cash.

If i'm not mistaken, NGK makes an Iridium plug, however I removed my NGK G-Power's in favor of Platinum +4's. The NGK's were burnt to shit after a year of service.

Sorry 'bout the side-thread here, but what exactly is "side gapping"?

Sorry 'bout the side-thread here, but what exactly is "side gapping"?


Bending the ground electrode to one side and very low so that the gap is "sideways" from the center electrode to the ground electrode beside it. Common when the piston dome hits the ground electrode in modified engines so as to still have a spark plug gap while reducing the projection of the spark plug into the chamber. Some plugs for some engines are designed like this from the beginning. It also allows much shorter ground electrodes which makes them run cooler which is helpful on cold racing plugs such as for nitrous applications.

The side gapping is usually done for the heat range improvement of shorter ground electrodes (if that is the problem), to make the ground electrode shorter so it won't break off due to detonation, and to gain clearance in the chamber. It really is not done to improve spark exposure to the charge. Most all of the time the idea is to get the spark as far into the chamber as possible...i.e...extended reach style plugs...to "touch" as much mixture as is possible and to get the spark as close to the opposite sides of the chamber as possible to reduce detonation. Side gapping will move the spark closer to the chamber walls which is really not good for combustion per se...generally speaking. Side gapping is done for several reasons, as mentioned, but better combustion is not one of them.
