Hi I found a obsolete Kf supercharger system. , It's never been used before and was made to be used on the 2.8 v6 in a Blazer truck. I'm looking to put it on a 3.4 v6 with the adaptor it came with for the stock 2.8 throttle body injector. I understand there are high performance versions of that stock throttle body. I need to know if the stock 2.8 or 3.4 computer system will adjust for boost. I don't know anything about these systems. Are there any other options as far as computers? Thanks Tim

 

Computer will not self adjust for boost unless reprogrammed. I don't know of any good way to reuse the tbi with a supercharger.

 

your car will only run for about 10 seconds before catastrophic failure occurs the 3.4 cannot handle that much power in its stock form trust me i was planning on turbocharging mine before i totaled it i did many hours of research on everything

here is what i came up with

So is it just a matter of getting a chip or sending the computer in to get reprogamed or do you have to data log it? Is the 3.4 a speed density or maf system? I understand a system with a maf or mass air sensor will work much better with boost. What's the 3.4's weak link, is it the stock cast pistons? I don't believe this is a system with a whole lot of boost, it's a small blower, not much more than 6 lbs boost.

 

stock your engine may handle 2 lbs of boost maybe... the weak link is in the heads and lower intake the exhaust side of the heads are way to small and the runners on the lower intake are way to short and its not as easy as just sending out the comp you need to tune it yourself as no one tunes the 3.4 thats the one thing ive yet to figure out

so basically what your going to need to do is a 3.5 top end swap you take the heads lower and upper intake along with the fuel rail off a gm FWD 3.5 (malibu or G6) and bolt it to your 3.4 i came up with just under 1300$ youll also need all new forged internals a remote timing retard system more fuel its very time consuming and costly all in all i think i came up with 2400$ to run a turbo and make 10 lbs of boost for that much i could have sold my car and picked up a 10k SS

 

Well with this supercharger system you have to replace the intake you run a special intake then you bolt the kf supercharger on top. It is about the same as a 671 supercharger in shape but smaller. I most likely couldn't bolt this to a 3.5 top end. I was mainly tying to find oud how practical this would be on the computer side because I had the adaptor for the stock v6 throttle body and I was going to use G . If the 3.4 wouldn't be a good idea I also bought one of the last adaptors BDS had for this supercharger. This adaptor will bolt this supercharger to any square bolt pattern Holley intake,It does have to be a engine small in size. A 4 or 6 cylinder at most.

 

put it on a 4.3 s-10

 

Obd1??????

 

the camaro... ya all 3.4s are obd1 the 95s are obd 1.5 basically obd1 with an obd2 port that doesnt work with an obd2 reader

 

I did kind of have doubts on the 3.4's strength. I wouldn't mind building a 4.3 , they are almost the same as Chevy V8 just smaller. I wonder if the throttle body for a 4.3 is the same type as a 3.4, then I could still use my throttle body adaptor I have for this supercharger? Of the two ob1 or ob2 what one is easier to tune?
