wow, i almost want to join so i can ask what kind of crack that honda moron is on......lol EGR valve

[crazy k]

LOL Bosch 4 + platinum?   those won't last 500 miles!

5. Use synthetic oil- I use Amsoil 10-30 or 10-40, this will extend
your oil change intervals to 25,000 miles, with oil filter change at
12,500 miles, and add oil in between for what you may use/burn off

 :bonk:

What about it? That's what I use...

[Jay]

But are you changing your oil once ever 25,000 miles?

[oldscsc]

But are you changing your oil once ever 25,000 miles?

It actually is worth 25,000 miles. It's 25k/one year. I change mine once a year. It only gets about 2,500 miles on it throughout that one year, and it comes out looking pretty darn clean. I wouldn't want to run it to it's 25k limit, but I do run it to it's I year limit.

[Breakdown]

Don't owners of car's with these engines in them have enough problems without this guy suggesting ways to make them far worse.

And Oldscsc, you should be good for about 10 years on each oil change at that pace, just make sure that you change the filter every five years and top it up a little.

My car ran like crap with the EGR unplugged when I did it out of curiosity. Wtf.

[3.1cutlass]

You probably would be better off to leave here than to come in and talk shit and run your mouth about all this "real" power that you make and telling our members how we are on a "factual bender"

[Jay]

I ran those 4-tip plugs in my 3.4 for 70,000 miles, NO PROBLEMS- that type of chamber and cylinder head actually benefits from a multi tip plug

the new 3800 series II comes with them stock, iridium 4-tip plugs right from the factory

you need to get your facts straight, and look some stuff up, you're on a factual bender

here's my "other" car- a 455 Pontiac + 060" = 470 CID making 500 HP

http://s5.tinypic.com/t5r336.jpg

I made the steel intake manifold and headers from scratch- it has tunnel port heads on it

I've been building cars since before you kids were born- and by your replies here, you kids have no clue what real power is, or how to make it.  If you stomped on 500 HP the pee would be running up your little chest and over your shoulders into the bucket seat.

notice, the 455 doesn't even have an EGR valve- no Pontiacs did until 1973- it's an emissions device only.  There's a lot of standard automotive knowledge out there you could benefit from, if you just opened your mind to it and tried it.  You've been weaned on anemic 200 HP engines- back in the day of the "real" American musclecar, anything under 350 HP was considered weak.

EGR and Cat converters are an IQ test, if you're running them, you flunked

Do 3800s have NASCAR heads as well?

You're sounding like Bruce Fulper on FWDs now. :mrgreen:

I was born and raised on Pontiacs so now you're in my arena.

Seriously, please leave the no EGR crap on Performance Years, they're stupid enough to believe anything. Not saying you didn't make more power than stock (more on that later) but these cars were tuned to have an EGR to run properly. If I unhook the EGR on my S10, it runs so bad, I can't even get it out of my driveway.

The only way these cars will benefit from unhooking the EGR is if the PROM is reflashed for EGR delete.

The reason it runs even slightly better with the EGR unplugged is because the computer is making the engine run richer when throwing the code. Which will kill the cat in short order. Removing the cat is illegal - not that I care! But if caught, it is a hefty fine. I don't recommend it, nor will I condone removing the cat on this site.

Many people are living in emissions strangulating states where they have to have annual emissions testing to be allowed to drive the car legally. Granted there are some ways around it, but again, I can't condone anything illegal on this forum.

Now, if you want to talk Ponchos, go to the other cars section and we'll do some bench racing. :mrgreen:

My past and present Ponchos include:

1974 TA 455SD/4 spd
1975 Grand Am 455
Too many 1973 A bodies to count...GTOs, LeMans and GAs
1977 LeMans Freeway Enforcer was 400, now 455
1977 Can Am
1966 Executive 389
1968 Executive Enforcer (Not sure if Pontiac used the "Enforcer" moniker in 1968, but it was a Police package 4 door sedan had a FACTORY 428HO - ex Ohio State Police car)
1969 Catalina 400
1969 Superior Bonneville hearse/ambulance with 428
1976 Annv. TA with a 455/4 speed combo and t-tops. 1 of 101 made and stolen 4 hours after I bought it.
Among others brother.

I still have a complete FACTORY NOS 1973 GTO Ram Air set up I bought at a GARAGE SALE for $35. :mrgreen: Someday, I'll find another GTO, Grand Am or LeMans GT to maybe install it.

I want to clear something up for once and for all on the bosch +4's and why they do NOT work on these engines.

First of all, the spark is going to take the path of least resistence, so if even one of those 4 terminals is closer than the other 3, it is always going to go to that one.  These plugs have to be gapped for the engine to run right.  Don't believe me, then don't gapp your plugs with you get them and see how well it runs.  

Second of all, the GM WASTE-SPARK DIS system that these engines use (2.8 MPFI, 3.1 MPFI, 3100 SFI, 3400 SFI, 3.4 DOHC) runs a spark that is SO HOT, it burns the platinum right out of the plugs.  When I stuck NORMAL platinum plugs in my high compressions 3100 (running 12.5:1) they didn't even last 50 MILES.  The ONLY plugs I can use in that engine are IRIDIUM or RAPIDFIRES.  The average lifespan of a +4 in the 3.4 DOHC is 1000 miles, and only on the weaker running ones, OR ONES THAT ARE NOT USING THE STOCK GM COILS, OR THE ONES THAT ARE USING MSD COILS WHICH IS HAS BEEN PROVEN DO NOT RUN AS HOT AS STOCK GM!!!!!

Third of all, not all of us are interested in making 1000 HP torque mosters out of our grocery-getters.  Some of are here just because we are fans of these cars.

I for one can NOT afford the fine for not having a cat, and I can't stand how the car runs with the EGR unplugged.  I think that if I have to have more power, and I want it out of my 3.4 DOHC (which I would gladly trade for a 3100) then I will just save my pennies, and turbocharge the bitch.

100 HP more, and it will still pass emissions.

[oldscsc]

Well bud, I think you need to rethink who is a "factual bender", which BTW don't really even make sense together.

Also, since you're into this kind of stuff, look up a chip on eBay. They advance your timing quite a bit. Your engine may only last 20,000 miles on one of the chips, but hey, you'll be making 15 extra horses. That's all that matters.

[Captain Intl]

My summer driver is a 87 Buick Grand National with over 500 horses and can do mid to high 11s in the quarter, so suck my tits... bitch. Who do you think you are?

There was a ..."disturbance"... that came along. Those posts were directed at him, not you.
