webers or injection, again!

I feel like I should be getting a little more out of my engine. I know we have discuss Weber's on larger engines and their limited capabilities. I have been seriously looking at TWM and Dynatek for a change. I would love to talk to someone who has made the change or someone who is familiar with either system.

I just don't seem to be pulling as hard as I think I should out of the corners and down the straights. I am running 48IDA's with 40mm chokes. I have 45mm chokes on the shelf. Should I just keep tuning the Weber's or go with the injection? How hard is it to set this stuff up? Any horror stories?

I just need some advice.

Dean Ive heard some stories:( but I beleive that goes with nearly all HIPO applications I know ther are some pretty sharp guys with ther laptops out ther to get things sorted with an injected engine hope you get things worked out without to many headaches:CRY:.We had a chance to go with the Webber setup at a local hotrod shop all the carbs manifold and linkage for 1500:eek:.I ask if he was for real,said he couldnt getm worked out ,looking back I should have got them and sold them here on CC.O well good luck I know you will get it all worked out...WB3:D

Dean,

I've have two motors with EFI (see below for some pictures) and I would definitely recommend that you consider the TWM setup. The EFI systems have the advantage of being able to provide a much better tune on any engine combination. A good system, properly installed, will also stay in tune for many years without any fiddling. Its more work and expense to get the EFI setup on the car initially but I think you'll be much happier with the performance and the lack of maintenance in the long run.

Also, EFI has the advantage of being able to make a fairly radical setup quite streetable. The block small block shown below is the first motor that I built with EFI and is a good example of this. This motor is street driven and runs on 93 octane pump gas. It starts and idles like a stocker and made 625 HP on the dyno.

Let me know if you have questions on EFI and the TWM system. Best of luck with your project.
