To make a long story short Im changing from a carb to fuel injection. Now for the hard part... what type what type?

I was looking at the commander 950 Throttle body injection from holley. It would perfectly replace my carb on top of my blower.

However, I want the best gas mileage, is this TBI system going to get me much better MPG or just a little better...

Which brings me to my next question, just how much better is the multi point system than the TBI system? is it worth the extra $1000 to go multi point? I know if I went multipoint, I would have to also get a centrifugal supercharger....
oh and is there a better multipoint / tbi system than holley out there?

thoughts / opinions - appreciated / wanted. thanks.

 

If i was going to add fi to a roots style blower i would look at blower drive services they do good work.

get out your credit history you'll need to morgage the house for BDS stuff.

 

yeah bro thats disgusting expensive. Besides im looking for somthing I can use in a N/A AND blown format. and somthing for MPG not GPM. hehe. but thanks for the suggestion!

 

A TBI might not actually do anything for fuel economy, but I am sure you are on track with an EFI idea. maybe an 8 injector plate sandwiched between the blower and manifold and the commander 950?

 

eh? injectors to inject what? if the commander is injecting fuel then...

My biggest concern is fuel economy right now. I want 20 MPG, thats my goal. If I cant hit that with holley's setup, where should I go from here. I know LS-1's are capable of that MPG and then some. They have multipoint setups though. I will go multi point if I feel it will net me the biggest MPG gain, but I will have to ditch the blower. No big deal, just more money to add a centrifugal later.

 

what I mean is to use this kit (see pic) and the 950 instead of the TBI kit and the 950. the TBI's are EVIL

 

<b>the TBI's are EVIL</b>
do you mean that in a bad way?

<b>what I mean is to use this kit </b>
what kit is that, how does it work, part number = ?, fuel economy is like..., where do i get it, how much is it.

heh, sorry for the list of Q's, maybe just a part number then? I cant find it on holley's page but I could be blind as heIl too...

and Instead of wiping out $2000 on a fuel injection setup I may just buy a 250 Powercharger or a 177 weiand instead. go for the power instead of the driveability...

 

TBI Rocks!
