LT1 383 / AFR 227 / 24x EFi / F1 Procharger FUEL SYSTEM UPGRADE?
Hi all.
I have a C4 vette which I recently started up for the first time after build. Tha car has a LT1 383, AFR 227 Heads, 24x EFI ignition system and F1 Procharger. The car has the origial FP with an inline pump added which is good for 125 PSI MAX as is states on it. Any advises would be appreciated! Do the original lines flow enough & if I upgrade my system, which one should I look into? I am guessing the car will be somewhere in the 800 HP range???
Thanks!

WOW i have a very similar setup but smaller ai trickflow heads and a d1sc and i find it very hard to beleive u could even run with a booster pump.......god yes u need everything 700+ is the edge what lt1(fuel lines, rails, pump, and fpr) fuel system can do, that means u would have to run new fuel lines to and from go to a double pump set up and get ur fuel rails drilled out for a new fpr and an fittings......i cannot beleive u havent leaned that car out yet, but please call LPA and talk to him before you lose alot of money.

Hehe sorry guys, I´ll explain myself a litle better. The car has not been driven since engine build. It was a half way finished project that I bought. Just finished assembling engine and started up just to se if it would start at all (only idle)! I did not think I could run it on the fuel setup that is installed and that is why I ask. The car is in Iceland and it does not make things easier ... I´ll post some pics if you are interested.

As said early contact lonnie at lpa and talk to him he will point u in the right direction for what u need.....U will need to pull your fuel bucket and rails and send to him you will need bigger supply and return line and also a boost referenced fuel pressure regulator. If you are a handy guy you might be able to tackle a dual intank setup but i strongly urge you to get the necessary wiring to do it right, like said earlier after spending 12-15k this is no time to cut corners call lonnie he will assist u with everything......just click on the LPA sponser on your right.GLWYB.

Thanks again guys!
I finally have the fuel system from LPA in house, nice one!!!
Can any one of you recommend a tune for the car? LT1 neededing boost possibly since we seem to have a simular setup? We have HP tuners, and the guy helping me is tuning
the LS engines but never had his hands on set up like this. I just want to stay safe, I heard something about needing scaled tune/map due to the size of the fuel injectors?
If any of you can recommend where to start it will be highly appreciated!
Thanks!

Where are you located? Normally for this kind of build I would only reccomend Bryan from PCM's for less, but the 24x will make it much less complicated for a full tune opening many different options.
If you are near the Midwest, Mike Norris does a great job. There are experienced tuners a cross the country though that should be able to help you out.
The biggest thing is just getting someone with experience on the same setup, and NOT someone with no experience with it wanting to "learn" off of your car.

The problem is that the car is in Iceland, which has not made it easier...
But hopefully I am getting towards the end of it! I was hoping to get a
safe base tune to work with (starting point) instead of starting from zero
and possibly screew something up! Maybe I´ll try contacting either of
above mentioned persons, see if they can help?
