IS THE ACCEL MODULE FOR AN L98 ENGINE WORTH THE PRICE? DID ANYONE EVEN TRY ONE? RESULTS?

Dave Farr

I replaced my 8pin, was way cheaper than oem and worked well.

I AM TALKING ABOUT THE MODULE WITH THE TWO PRONGS AND TWO OVAL FEMALE ENDS. THE DISTRIBUTOR IS THE SMALL SERIES. HOZZ4

I tried one, made little or no difference in the way the car ran, and it wasn't any cheaper than a quality one at a parts store. I ended up keeping it for a spare.

I personally have been more impressed with the MSD components than Accel.

Shagwell

...I'd go with the MSD module now that they have one for the late-model HEI. I've had to many problems with Accel products.

- Unless you're turning over 5500 rpm an aftermarket module isn't gonna do anything a factory replacement won't do.

Xlr8torZ28

iTrader: (19)

actually I think the stock ignition components start fizzling out after 4600RPM and supposedly just fart after 5000rpm

Shagwell

..with the old, coil-in-cap style HEI, yes, around 4600-5k. I've had no problems w/ the later-models to about 5600, maybe 5800 with fresh components.

You may be right... I may be thinking of the old school HEI... I know the newer ones didnt go too high because GM knew the cars werent made to go that high, they would have been cutting off their own feet in warranty claims because the factory press in rocker studs start inching out after 5000rpms (unsafe for valvetrain)

Dave Farr

Well my late model 8 pin cost $50cdn and oem is $80. Cruise on the highway had more power. whats the part number for the msd 8 pin?

I always go to Summitracing or direct to MSD and search the parts.

shaggy56

How would you rate the pertronix flamethrower versions? Better or worse than accel?

HOZZ4

I ACTUALLY HAD SOOO MANY PROBLEMS WITH THE ACCEL PART (AND I TRIED TWICE WITH TWO NEW PARTS FROM SUMMIT) THAT I'LL NEVER BUY ANOTHER ACCEL PART AS LONG AS I LIVE. IT WOULD RUN LIKE I HAD CRISS CROSSED SPARK PLUG WIRES AND IT OBVIOUSLY REALLY ACTED UP WHEN I HIT IT. ACCEL SEEMS TO BE JUNK IF YOU ASKED ME.

90CamaroTBI

How do I know which one I need for my HEI, there are several different ones. I have the external coil.

HOZZ4

YOU CAN GO TO THE SUMMIT RACING WEBSITE. JUST PUT IN THE INFO ON YOUR RIDE AND EVERYTHING IS STRAIGHT FORWARD. THEY HAVE MOST AFTERMARKET MODELS TO PICK FROM. JUST STEER FROM ACC--...OOPS... DID I SAY THAT..

90CamaroTBI

Does it just pull out and the new one slip in? I am sure it will help over my stock 200,000 mile one.

90CamaroTBI

Well I guess I have to get Accel because the only ones it lists on there is Accel. The MSD is only 4 pin or something instead of the 8 pin thats stock I guess. I dunno whats the one I seen in a Chevy magazine that just goes in easy....it was black uhhhh anybody know?

shaggy56

How about the pertronix I mentioned earlier it comes in 8 pin.

90CamaroTBI

I want the pertronix one but stupid sites dont list it, they only list the 4 and 7 pin ones. Where could I order a 8 pin one from? Thats what I think my external coil takes.

How in the hell did you find that lol, it dont even come up if you search for it.

Their are two different ones.

Here match yours up.

pigsticker

Do you have a clue to what the difference is between part #2002 and Part#2003?

chevyboy07 91

i have the accel sitting in my tool box for my 92. I keep burning the stock ones up and the ones from the parts store (Borg Warner) only last about a year for me.

Anyway, i tried to find the correct one through MSD and at the time they just didnt have it...they didnt make it. Maybe things have changed now, but i hope my accel works out for me!!!

Driberif85

I have 2 cars both use the same ignition module. The both run small cap distributors. I had the one ignition module last maybe 5 months. I also was running an Accel coil. It lasted about 2-3 months. I emailed Mr. Gasket/Accel about it. They told me that they thought that I had the wrong application. Bottom line do not buy Accel.

90CamaroTBI

How the hell can I match it up, I cant rip the car apart without having the part to replace it.

shaggy56

Im not sure of the difference but this is the part thats comparative for your vehicle. I was able to cross reference the correct part.


Thats for a 1990 tbi 305

was gonna post a link to summit but this website doesnt seem to want to do that.... sorry
the msd part number is 8226

91RamAir Formula

8226 is the part number for the coil not the module? anyone know the module #

I TRIED THE ACCEL MOD, GOT IT FROM SUMMIT. PUT IT IN MY CAR AND GOT ABOUT 8 MILES OUT OF TOWN BEFORE THE CAR JUST DIED. THIS HAPPEND TWICE. I WAS LUCKY BOTH TIMES I HAD THE STOCK ONE WITH ME. I NOW HAVE THE MSD DIST, AND IT WORKS AWESOME!!! IT'S A DROP IN AND PLUG TO YOUR ORIG. WIRES. JUST MY !!!

HOZZ4

PLEASE GIVE ME THE PART NUMBER AND WHERE YOU GOT IT. I NEED IT BECAUSE THE JUNK ACCEL ONES DID THE SAME TO ME.

shaggy56

I second that. For the life of me I couldnt find the MSD part # for the module.

Xlr8torZ28

iTrader: (19)

I have a MSD module on mine. I checked summit and MSDs website, and apparently it looks like they dont offer it anymore. It is still used in their HEI distributor which means they still make it. I suggest calling MSD to find out if it is still available by itself.

Xlr8torZ28

iTrader: (19)

I just got off the phone with MSD. They do not make a module for the HEI with external coil. I got mine out of a used MSD distributor thinking it was an upgrade. They use stock GM modules in their distributors. He assured me that the stock modules were fine to use with other aftermarket ignition components. He did tell me to make sure I use an actual GM module, and not a cheap one. Hope this helps

I'm running an OER 8 pin module in my TPI305, it was 55 bucks at the parts store and works fine. Its more or less a GM part and they have a one year warranty. OER makes two different 8 pin modules, spend the extra $15 bucks for the better part.

Believe it or not back in the day Accel was the best **** around, then they moved to Mexico .

Xlr8torZ28

iTrader: (19)

LOL... Accel did use to have some decent stuff, but now I consider most of it about the same as autozone performance parts... lol

Red Devil

I've found that most of the modules are comparable.

Since we are on this discussion, I always feel the need to add this in as I constantly see people doing this.

Do NOT use dielectric grease under the module, use the right stuff, thermal heatsink compound. Many of the box store ones come with the dielectric crap. What you want is the white or silver colored stuff.

Wells part # SL-203. And make sure the parts boys give you both tubes in the box, lately I've had the parts boys pulling out one tube from the box and trying to charge me the full price. It should be two tubes in the Wells box, IIRC blue and white box.

yeah, i go through a module about once a year. i was running the autozone wells 8 pin ($35) and it was fine for a year, then i went to Napa OEM and that lasted 2 years... I went back to autozone since they got a limited lifetime warranty on the Wells modules. They will probably try to test it, and tell you its still good (they always test out good for me). But when i put a fresh one in it fires right up. I admit, i just bought an accel module and it cost like $60.... When i first installed it (remote mount coil) the car wouldn't start, i took the dist. off and checked the connections and the white jizz on the bottom. It fired up this was one week ago, and its still working. It still feels the same as the cheapo wells brand, so i suggest you save the money and buy good plugs and wires or maybe a MSD6AL box, although i think my box is the reason i burn up modules in the first place... its a catch 22 i think

Blu91Z28

I've been running the Accel Module/MSD Coil combo since '01 with no problems. I've put roughly 70,000 miles on the old L98 with between 200-300 passes at the track.

Dave87IROCZ

I dont know why everyone bashes accel. The delco modules kept burning on me so I got an accel and it works great. I also have an accel coil 5 years and my old u groove plugs were about 3 years old before I just replaced them. I also have accel cap and rotor and extreme wires. I took the advice from people on this site that said the accel injectors sucked and the ford ones are good. So I got the ford ones and they are shorter than the stock ones and barely seal. I just got back from the track I ran 14.5 My car is bogging a low rpm because I put 24#s in. When I hit third it falls on its face for a bit before it takes off again. Im getting a chip from pcmsforless and expect to run mid 13s.

Dave Farr

The two different 8pins are for different year applications. One is not better than the other just because it costs more.

tagta189

Guys I'm an electronics tech and I just wanted to warn you to make sure that you thoroughly clean all traces of the old heat sink compound off before you put new heat sink compound on.Like they said use the white stuff.The old stuff gets hard and will prevent the new component from from being able to transfer the heat it generates away.It will run for awhile then burn up.Make sure that surface is clean...

Dave Farr

I want to change my opinion of these modules- was just towed in because the Pertronix 8 pin died on the highway. The stock GM module would drive the Jacobs Ultra coil reliably when the Accel module would not, and the Pertronix just died. I guess that MSD has the right idea using proven OEM stuff- I believe the GM Ramjet had a different variant module I couldn't get any info on it though. With all the different GM part numbers for the computer controlled 8 pin is there a 'hotter' module from the general or not? I don't know if running an 045 gap on G-powers will kill it too (vortec heads for a 89 k1500 TPI). These guys didn't even have to invent a 'new' module but copy and improve GM's module- I just don't get it, I want the advertised improvements but......once bitten twice shy.

I wish I would have read that last week, but no big deal. I ordered an MSD HEI module PN #83645 from autozone paid $78. I just changed my plugs with rapidfires, MSD 8.5 wires, cap&rotor, and blaster coil. The coil must have been on it's way out, because as soon as I took it for a drive after I put the MSD one in it roasted the tires when I punched it I knew the MSD module looked to big, when I got it, but took the cap off anyway,(changeing a few on my vette's me) and yup, wrong one. The module on there looks to be the original 95kmi one, or pretty old, as the nuts are really rusty. Is there another brand(besides Accel) that I should use, should I get a new delco, or don't fix it if it aint broke?

Dave Farr

don't 'fix it' let it be, but if its the old hei coil in cap, msd's got some quality modules for it- they just don't make them for the small cap hei.

I guess I wasn't very clear on my last post!!!! (sorry) I have the small cap dist in my car without the coil in the cap. I had two of the accel mods in my stock dist, and both were junk. They both burned up on me. I was not a happy camper, so I bought a MSD complete dist for my car. It works awsome. I guess I should have went that route since I am running a msd dist, and 6al box in my 70 chevelle ss 454. Msd is the best stuff I have used. Just my

Dave Farr

MSD's secret of reliability with the small cap HEI distributer- is GM's module.

F&Ybodlover

so, the MSD distributor for TPI F-bods with external coils use the stock delco module?

Dave Farr

Thats what MSD says- I tried to get a part number to order the module from their billet dist.
