so i am guessing they changed the gt-4 rules to allow the use of fuel injection and 45 mm throttle bodies.

i think jenvey has the best tb setups
they have the DCOE style in a standard length and a size that is half the lenght of that which i believe would help in tuning by changing the lenght of the air horns
also for a fuel injected turbo application it allows alot more plenum volume with out cut into your gt

i have never heard of the sds computer systems
are they descent priced easy to tune?
can you give me a link
thanks

i found the site
its not all that expensive but it looks like a very simple setup
why would you need a dyno you can just get the base settings and then go drive the car
and if yoou wanted to tune you car at the track the little programmer is alot easier to deal with than a laptop

please excuse my use of words but for a budget efi conversion that you can tune you cant beat it
you will be fine tuning by the seat of you pants as long as you have the air/fuel and spark advance right
and to get full potential out of it you could go to a dyno

i fully back you but for street its nmot that critical as you say and that what i mean
i plan on using a haltech computer and spending way too much time and money on a reliable high hp engine
but for a carb to efi conversion that kit takes alot of things out of the picture to simplify it
and i back your idea fully i just wasnt meaning the hipo part

were the new rules open to all racer in this class or just the opels
because it seems like it makes so much more of a difference in power to the restrictive carbs
