Thread: Fuel injection

Tweet

a suburban with a 383 run like a scaled ape??? Pulling all that ballast around with it, doubt the 383 will be very impressive. The only thing better than cubic inches is more cubic inches. BTW, throttle body barely qualifies as fuel injection, anyhow. if we were talking a multi-port, the change and calibration on the electronics might be worth it.

I have an Enderle bug catcher for my Z-28, with an E.F.I. conversion. Iv'e been told it will be very dependable. I don't KNOW that from experience though cuz' for now it's bolted to a foam mock up engine HEHEHEH
Probleee not de best reason, but one reason I bought it wuz' cuz' the bug catcher is shorter than a carb/air cleaner combo. and I'm aimin' to make the "Z" A.L.A.P. (as low as possible) and still keep the pan off the ground (Found a 7 1/4" Deep Pan) and be able to see over the huffer/injection. Set the whole thing up in the car before I tore it apart just to see how things were gonna fit and I can see over the bug catcher pretty good. Hope the local police agree. Hey, I letter all the squad cars around here (got one comin' in Monday as a matter of fact) so hope they cut me a little slack

Good points all, Dave. I was trying to be nice. If off roading is the goal torque is more important. The TBI setup would probably be sufficient for that once it's properly sized. Maybe an Edelbrock Pro-Jection type setup?

I agree that TBI barely is EFI. But it's still better than a carb. I like my SFI (sequential fuel injection). It was WAY ahead of it's time. Fairly common now, though!

Multi port fuel injection is very good fuel injection but, TBI is nothing more than a carb that has fuel injected into it and, it can sometimes be better than a carb but, not when u have a Predator cause they ajust themselves so there never under or over caurberated. I agree that he should use what he feels is best for his application, we can just give suggestions. I misread the post and that is why I put Blazer instead of Suburban.

We were getting along fine and sharing information like adults until someone turned it into a personal attack on me. Still don't know what I'm supposed to "earn"

Just trying to help and offer some info. Many others have done the same for me when I had questions and I thank them for it.
I certainly don't know everything, but will offer advice/info in areas where I'm qualified to do so.

It was just a joke. Don't take life so seriuzzz.

If I offended you I'm Sorry!!

Sorry for the confusion. It wasn't you who offended me! Your post was hilarious

I don't take the choice of car parts seriously. Personal attacks and insults I take VERY personally. Especially from people who don't know me.

Hey Sin
Your suggestions are and will all be taken into consideration. I have no idea where the comment from Streets came from, suggesting that you have to earn your badge prior to your voice being valid. He hasn't been on here even a year, so if length of membership counts for anything, we are all pups. If post count is supposed to rule, I would suggest just the opposite. If age dictates, I suppose I rule at the ripe old age of 53.

My vote would go to the one who has been there and done that. And as of yet, I do not have anyone in this form in this thread speaking from experience in my application, which is a TB 89 4X4 Suburban, programming the existing system to handle 400 plus hp. The current TB doesn't count for a whole lot and especially when I have the local pros tell me that it can not be done.

I liked the mega squirter link, and as I already stated, I might try bulding that for my own daughter's car, but not for a customer who doesn't know a fart about hot rodding or tuning!

Last thing I need is for this motor to melt down because of some advice I get over the net.

I don't know where the animosity came from either.

Good luck with your customer's Suburban! In your case it's all about what makes the customer happy! Just didn't want you to overlook an option that might work for similar money. I haven't done this particular job, that's why I provided the links in the earlier post. Those guys can probably tell you for sure if the TBI is even a viable option at that HP level. If you'd have to buy some other complete EFI system, cost may become prohibitive.
And from what you described as the owner's intended use of the vehicle it might not be worth the hassle.

I have a good bit of experience with EFI that's why I posted. I also consult others who know way more than I do. In a forced induction setup (like mine) fuel delivery is critical to keep from leaning out and destroying the motor.


Out of curiosity, did you once own a Typhoon? (<--old Screen name)

TyphoonZR, ur customer probably wants 2 save money and a carb would provide those savings but, EFI is more efficent but it cost's more. If u can make the original TBI work with help from the sites Sinister suggested, than do that but, if you would have to change the whole system to another, ur customer will probably want the carb due to it's cost diffrence.

Yeah Matt, cost is a consideration so we are sticking with a carb.

V6, my nick is TyphoonZR but I did not own one, I made a clone out of a 4X4 and an AWD transfer case, then stuck a 600 hp sbc 406 into it aand then added another 250 via juice, just to be sure! hehehe!

Hmm theres nothing like a good carb, of that theres no doubt. However, when it comes to EFI, multiport or sequential has the power. When it comes to reliability, il take TBI. Simply means less to break. Thats my two cents.

That's cool, Tycoon(TyphoonZR)! Wonder if the guys in the SY/TY section over at www.turbobuick.com have seen that one?!?!
