I want to go to a supercharger, but no viable system exist for TBI for our cars. SOoooo, I was thinking about going to a TPI type system or carb in order to do so.

Any suggestions on this matter? I don't want to abandon the TBI, but I'm bored with my power level and the new cars out there are getting faster every day.

 

When did you decide that no option exist for TBI. There are many supercharger kits for TBI applications. The EBL supports 4 bbl TBI units AND 2-bar MAP sensors.

 

EBL . . . as in that aftermarket computer thing by one of the guys on here? I have no idea how to tune even with ALDL, so I don't even know where to begin on that. I remember asking about that a few months ago, but I've forgotten what was said . . . I'll do a search on that I guess.

To my knowledge, all of the TBI supercharger applications out there were for trucks. Now assuming the computer and electrical issues are somehow fixed by using the EBL, we would still run into clearance issues. I have no desire to go and pop for a new hood after all of the trouble I went through to get this one painted right.

Maybe I'm just crazy or stupid, but I'm still not feeling it. Enlighten me about the possiblities . . . I'm all ears.

I'm looking for somewhere around the 425-450 hp range.

 

Well for one the TBI actually takes up less room than the carb you are talking about running. Holley makes a 4bbl TBI unit that will support the power you want to make.

How do you expect to make 450 HP with TPI and no tuning? You won't make 450 HP carbed without tuning.

The only reason I mentiond TPI is because I know the kits already exist out there for 3rd gen F-bodies and the tuning support for TPI is far greater than TBI . . . not to mention the hood clearance issue with the TPI setups.

I've been to his site, and don't understand half of that tech speak. I am telling you, I am a tuning retard. I've tried for 5 years to learn this crap, spent lots of money on tuning hardware and tuning sessions and reading countless threads about it, and I still have no idea about what people are talking about even in the basic newbie threads.

 

If you can't get the tuning down, you absolutely do not want to go forced induction with FI. You'll just be asking for a blown motor. TBI is no different than carb when it comes to packaging, other than it's about 3/4"-1" shorter. So that would pretty much rule out a roots style blower for either carb or TBI. The only way for you to keep your hood is to go with a centrifigal SC. They make kits for carb applications, which could be adapted to TBI very easily, but I think in your situation you would be happier with a carb. I wouldn't saddle yourself with the TPI setup. You'll have the same tuning headaches that you would have with TBI, actually you would have more since you would have to use the sy/ty code which was intended for a 6 cyl. It's doable, but a bit confusing. The EBL would make tuning for boost very easy, but your still left with tuning. All in all it sounds like your car is more of toy than a daily driver, so slap a big ole holley on it and go on your merry way.

 

I don't think you need to spend the money for the supercharger to reach your goal.

Those heads should be able to make atleast 400-425hp @ the flywheel with the appropriate camshaft, manifold, carb, distributor and tune-up.

I'm gonna vote for a carb setup... There should be a shop that in your area that can assist you with getting it tuned up. The trick is figuring out who is really good with a carb.

 

^^I second the Carb route Gunny. Set you're ECM up for a constant Open Loop state (take advantage of you're electronic spark control), and get whatever intake, cam and carburetor of you're choice. Don't discard TBI altogether just yet though, as the best is still yet to come...

 

Gunny did you ever do anything with this?

 

Carb supercharger + TBI adapter plate + diy diploma in PROM tuning

 

At the moment no. With work lately, I haven't had the energy nor the time to do anything with it except give it a bath.

I'm thinking about giving the whole PROM thing was last shot, eventually doing the EBL thing-a-ma-jig. However, since I moved I left my other cars down in GA, so I have nothing to drive if something goes wrong (which of course will happen).

Believe me, everytime I turn the key I wonder what it would be like if I would just buy the distibutor, manifold and carb and be done with it. It's just soooooo much easier to slap on a nitrous kit or a supercharger with a carb than worrying about whether or not the computer is freaking out or seeing that stupid SES light come on for one reason or another.

Most of my currency goes towards furnishing my new house at the moment and I have this crazy notion to eliminate all of my debt . . . but everytime I sit in the seat I want to do something to it. It's like I'm never satisfied with it . . . and I have this feeling even if I bought a Vette or something, I would still never be content with what I had.

 

i know the feeling.

i'm for a carb swap...

 

This is because your a CAR ENTHUSIAST!!! O the joys of owning a car and modding on a budget. best of luck in finding your target.

 

i really wish there was as many after market options for these cars as there are for friggin 5.0 stangs, jesus i have never seen such a selection i think the after market for stangs is bigger than the ***** scene lol.... sucks that a 5.0 with a simple turbo or vortec kit can pull like 4-600 to the wheels with some basic supporting BS mods.... and we have to sit here and struggle to piece together a dam kit and modify like 80 things or rip our motor out for a LT-1 or LSx.... isnt thirdgen life wonderful LOL

 

Actually we have it much better than you realize. We have the entire small block chevy aftermarket. Any thing that will work on a carb motor will work on a TBI motor with tuning. Any vortec, roots, or turbo setup designed for a carb will work with TBI. If people quite looking at TBI as the bastard child of the car world and just realize it's a computer controled carberuetor with an air flow and fuel limit some where near 400-450 hp NA.

The 302 is actually a really bad motor to mod, the stock heads make swirl ports look awsome, the blocks have a nasty habbit of cracking in half at anything past 400 hp. They do have a crap load of intake and header options on the market, but those are really aimed at the uninformed enthusiast....which the mustang has no shortage of.

 

LOL basterd child of the car world LOL
Yeah back in the day when I was just learning about TBI, I would describe it to friends and such as a carb with electronic injectors on top instead of just feul being dumped in.
