I have a 89 Formula that I put a mini ram, 58mm tb, and Paxton s/c on along with other mods. I do not want to start burning chips or getting involved with switching ECMs. Has anybody else out there just given up, sold everything, and switched to a carburator?? I think thats where I'm heading. JImmy

Let me tell you, I certainly feel like switching to a carb. TPI has given me so many problems as of late, and I know I can get alot of money for the TPI setup, fuel rails, and wiring harness on ebay. People pay alot for these setups especially when it is complete. I'm not sure what to do yet.

I've decided. I'm selling my new (less than 30 miles) Mini-ram, 58mm throttle body, Paxton supercharger and the old TPI set up. I'll give somebody a gooddeal if they buy it all. Jmmy

Look in classified. I have everything for sale. New MiniRam COMPLETE, Edelbrock 58mm tb, and Paxton s/c with all books and manuals for 2500.00

gave up on carb and switched to TPI that is.

I had TPI, switched to carb and sold everything, now a year later I really realized what it was that i did! big mistake for me, I daily drive my car and i could never get it tuned perfect with the carb.

Yeah it ran great and it was cheap but in the end... I prefer the TPI and the fuel economy and the torque. the tunability is there too, I run the commander 950 so i dont have silly chips to burn and play with, so maybe you should look there if your sick of chips and factory wiring. burning your own chips is easy and somwhat fun, and you have more options with that than any aftermarket system, but you have to face the facts... It took me 55 chips to get my combo tuned in right... almost 5 months of tuning for the factory computer...

with the commander 950 it took me 2 days.

When I got to the point where I was ready to start burning chips, I thought about it for a couple tenths of a second until I realized that going through all that work and expense to switch to a carb, then spending months figuring out how to tune a carb, all because I didn't want to burn a chip or two was silly. I bought the burning equipment and I'm enjoying my "carb tuning" without getting dirty and full of gas.

And at least with TPI, you can plug in a scan tool and get real-time data for what's going on. This makes diagnostics a hell of a lot easier than in the carb days when you had to erect a voodoo worship stand and pray to the Venturi gods for answers.

Man i hate carbs........... FI all the way

I'm gonna switch from TPI to carb. I've been collecting parts for a new 383 for a while now. I'm just gonna take the 350 out with the tpi still on it and put the new 383 in it's place with the victor jr and speed demon. I guess if I decide I wanna do something different I can build the 350 up and swap it back in place.

jdaniel

is your stuff still for sale? if so pm or eamil me

just switched from carb to TPI.

after 1 day of tuning the TPI runs better than the carb ever did. More power, smoother, better throttle response, faster starts. I'm sure it will get better as I dial it in.

Everything except the S/c is still for sell. I'll sell the MiniRam w/rails and regulator, Edelbrock 58mm TB, the MAF and the stock TPI setup for 1300.00. Thats everything for the price of the MiniRam. I also have the EXTRA fittings and stuff that you need for the MiniRam installation. JImmy

how do i get to classified

https://www.thirdgen.org/classifieds/

there

don't sell it, you'll regret it later.. just throw a carb on there for now to get you going, that way you can work on the FI system little by little
thats what i'm doing

shiyet man, i'll take it off ya hands if you'd take payments. I'm going to stick with TPI, and what you've got is among my ultimate goals for my IROC.

I went from TBI to Carb...thats different in my eyes tho. Carb runs WAY WAY better than TBI ever did. Starts easier, idles better...everything. Im really thinking about switching in a TPI setup tho. I might start collecting the parts for the swap soon. I get crappy gas milage...it sucks. I NEED FI AGAIN!

I now have a 406, Brodix track 2 heads (220 cc), Eagle crank and rods, JE pistons, Demon carb and solid lifter cam Etc. I'll being cranking soon and trying out. I'll keep you posted. I sold all my TPI stuff.

Don't forget... a FI motor lasts a LOT longer than a carb simply because the oil is not washed off the cylinder walls... I read that a small block will last something like 200K miles for this same reason.
I just built a 406 and put a TPI on it.. after years of carb tuning I really like the TPI (plus it really looks high tech!!!)

where did you hear that?

Suck it up, burn some chips, learn some things. FI is the way to go....

I used to do a lot of carb tuning on my older cars. It is cheaper, but the gasoline fumes give you a headache, plus the girlies don't like riding around in a car that is running rich with that awful stench lingering around the car...

From John Baechtel...He was editor of Hot Rod Magazine and the TPI Swapper's Guide he wrote is a treasure trove of info..
But, it makes sense that if you send a 'metered' amount of fuel into the combustion chamber it should do just that.
The fact that fuel injected motors get better mileage kind proves that there is less fuel getting in there.

Here are some other books he authored:

Do you maybe mean that fuel isnt washed off by oil on the cyclinder walls? Like saying oil becomes saturated in gas?

Come on guys....how hard is it to tune aHolley?????? In 4 passes you are done. Set the timing, rejet a fewtimes initially and go.

Not saurated, WASHED OFF and burned! Why do you think if the carb is running rich it smokes? It's the oil being "washed off" the walls and burning... hey, I am just passing on info that he said GM gave him regarding the life of a motor running EFI vs Carbs

Gasoline is a great solvent, just stinks.

I agree though that an engine that runs overly rich is not prone to longevity. I don't mean to say carb motors aren't going to last because they will. Like the guy said, "how hard is it to tune a Holley." Or a Speed Demon, I have used a few of them.

However the nice thing about EFI, provided its all tuned correctly, the injector only sprays the amount of fuel needed. I think its easier, albeit more expensive, to tune EFI engines.

To each his own, EFI or Carbs...
