I have not yet seen it done to an 86-87 model TransAm. I have a 350 TPI that I would like to supercharge is this do-able? Is there a reason tehy only sell the kits for 88+?

It's because they don't make there kits for V-belt equipped cars. Since your engine can't be original maybe you should check to see if they swapped it with one that has a serpentine belt system.

BlackMagic: Great question, but its the v-belt thing as stated above.

Darcom: Great to see that you still visit thirdgen. If you remember me, I was interested in dropping by your place in San Antonio during one of my business trips.

Can you detail the things that are necessary to install a '88+ SC setup on an '86 or '87 car? And, since I burn my own chips, do you think its advisable to still use the MAF sensor. BTW: I finally built my big cube SBC motor.

Well the year was 1997 and I can tell you how I did it sense my car is an 84 it made it a little easier.I deleted the ac compressor to make way for the vortech .I did not have any brackets or pulleys ,but I was at my local speed shop and they had a ac bracket for a vortech motor,at the time I thought it was for a vortech supercharger,anyway once home I realized it would not fit but it would if the ac part of it was not there, so I cut it off now I had my spacer that bolted to my heads .I lucked out again and found a used vortech plate witch holds the supercharger and found out that it bolted right up to the other bracket I cut. now I had my blower mounted .now all I needed was a crank pulley so I found a 6 rib pulley at the junk yard had a aluminum spacer made to slip into my existing crank pulley . now I had a belt on my mounted vortech. at first I had a few alignment problems but washers made it all work right. anyway no one had parts at this time to do what I wanted so I basically had to monster garage it. it sucks that there is not a kit out there to make it easy but I guess there were allot of changes in belt configurations in the 82-87 years, it must have not been very cost effective to produce. but if you do get this far and can mount one well the there will be even more thing to consider .1 you will need more fuel and a way to change your timing for boost. and I highly recommend some sort of intercooling it will help in tuning and keep your motor alive longer. this is the only picture of the bracket I had to fab,and at this time I was testing to see if my new j-trim would fit. it fit like a glove.

as soon as I get all my parts to my 454 small block I will disassemble what I have an take detailed pics of the brackets sense this issue comes up from time to time.

Alright, my car does not run a v-belt system, my car is serp belt. It is also a 350, and not a 305. I was told that my motor is factory, but i must disagree, because from i understood, only the camaro came with 350 in 86! Any Comments?

DARCOM

if your car has the full serp setup thin i would guess that the vortech kit would work for you unless yours does not look like evey one elses serp setup.

Please tell me your kinding, if not look at the History/Restoration Board there is a thread there about the existance of an 1986 350 F-body. NO 350 '86 F-bodies.

Well i am not kidding that i have a 350, so there was a swap at one time or another. I know that it is a chevy motor, or so i have been told from when i took it to a shop in town. I do not run V-Belt, but run Serp...so does this mean if i want to Super Charge i will have to go a custom setup?

CamaroFreak406

I wasn't asking if you were kidding about you having a 350TPI engine I was asking if you were kidding about the stock install of the 350TPI in '86 Camaros (That didn't happen).

If your engine is out of an 88 or 89 Then the supercharger kit from Vortech will work, If the Engine is out of a 90 to 92 then I think you need a different kit (MAF vs. Speed Density) but I'm not sure.

Even if your engine is an older block (earlier than 88) the supercharger bracket should still work. If not get yourself some Eaton M90's and do a custom set-up, and if you do it right you can get more horse than the Vortech set-up for 1/2 the money.

Well My Procharger kit (88-92 Intercooled TPI kit) is ready to ship, so I'll let you know all that is involved/needs to be changed/modified on my 85.

BlackMagic

Sorry CamaroFreak406, i was having the worst day believable, and i was somewhat jumpy in the previous post. I still do not know all to much about 3rd Gen, this is my second car and i am only 16. So i have much to learn, which is the reason i come to this forum.

I might be wrong about the motor size in the car, but i was told that it is a 350. If they were right i dont know. I know the car has a considerable amount of modifications done, but what exactly they are i am not sure. I know that there has been a shift kit and some suspension work! The motor is not a v-belt, so if the factory motors only came v-belt then i know it has at least been swaped...

once again sorry about my previous respons....

CamaroFreak406

No Offense taken, I don't let much of anything get to me on the internet. I do this to relax and have some fun, it isn't worth getting mad over.

Hey if your only 16 and you've got a 1986 T/A with a TPI your better off then I was at 16 (I had the 1984 Z/28 in my sig, but with the stock 100K 305 in it, but it was fun and fast for a high school kid car ). But hey good luck with the supercharger install (I would go with a custom S/C install with an M-90 if I was you, it's a great learning experience and far cheaper than buying a kit, plus there is alot of information on this site to help you out).

Garret,

Thanks alot, and i do agree, there really is no use to get upset over the internet. I do consider myslef very lucky to have my TA. It is my second car luckly, because my first taught me many lessons. (blew the motor on a rare 1992 Dodge Daytona) Dad just about killed me, but it all worked out perfect.

I will look into the S/C that you recomended and see what i can find out about it. Thanks alot..

Very easy to do either way...At one time paxton made a kit for v-belt cars>>>But its long discontinued from what Ive heard>>>

Reason was it only worked on from 1985 to 1987 with TPI intake>>>which equals LOW NUMBER OF CARS>>>thus not worth tooling up brackets for..

So what you do is buy a blower for an 88>up car...then buy the PASS side serpentine bracket>>>you need that bracket>>a serp crank pully, a serp PS pully>>you can reuse your PS pump but just swap pullies..then you need a serp water pump and pully and a serp alternator...

There are guys selling this stuff all over... I paid maybe 100 bucks total for all the stuff to convert mine over...

I sold it all to madmax a couple of years ago But bottom line was its not a very difficult install..

Black Magic:

GM built just 50 cars with 350 engines in 1986 model year. All of these cars came with the 9 bolt rear end. So, I figure if you have a 9 bolt rear end, then you have a rare car for an '86.

However, all '86s had v-belts, so that is for sure a mod someone did to the car.

shawnc16

Ive got an 86 IROC with serpetine. Its stock but the power steering is run off a v- belt.

BlackMagic

i just went out an checked the rear end, and i have a 10 bolt...this is really starting to bug me, i am going to have to find the motor vin and find out my self.

smokefan

they used to use that half *** serp/v-belt system before going to a all serp set-up

CamaroFreak406

Those 50 cars were test mules (All camaro's) and the 8th digit would have been an F because the 50 cars were 305 cars pulled from the production line and had 350 installed.

Also right after testing had been completed all 50 of the cars would have been sent to the crusher.
