tuned port to carb my buddy and me are putting a carb on his gta, finished with the tuned port!!!! we've got the swap done almost, just have some questions about fuel delivery.
we left the fuel pump in the tank and will be using it. we have an adjustable pressure regulator and are wondering whats the best way to plumb the system? feed line into a t fitting with return line and regulator? the pump is an older holley in-tank tpi pump.

Run a return style regulator. I allways drop the tank and remove the pump and install a line to the bottom of the tank and mount a holley blue in fron of the axle on the driver sode. Works great every time.

we left the pump in the tank basicly because it's a high flow and it works.
were just a little baffled about how to hook this thing up to the carb with the regulator and the return line.
tuned ports are great until about 4500 rpms, then they're done.
his car was already in the 12's, and instead of putting the time and money into the tuned port set-up and pcm chips AGAIN, we put the carb on.

A few of us in the Ford world are using this one http://store.summitracing.com/partde...5&autoview=sku
I have the same one and my combo is going from EFI to carb. It uses 3 lines so you can go feed, return, and N2O.

well I got money and I really dont want to spend 410$ for TPI base,352$ for runners,320$ for TB,110$ for fuel pressure regulator and 400$ for injectors and all that just for intake manifold upgrade well in the carburetor world all you need is a 210$ RPM air gap and 440$ for 750cfm mechanical nothing more
Its all about the length. Shorten the runners, and watch the HP and RPMs go up.
An LS1 with a carb on it?
Why spend the money for the good bottom end only to cripple it with an antique intake. Fuel injected engines should stay fuel injected! An LS1 with a carb on it?

ha!
carburated lsx over ANY efi tpi any day of the year
you are grossly misinformed, friend
but i will make no attempt at changing your mind, since i dont care
just hope u never line up next to to me on the street or track
or some one with else with it

[/QUOTE]yeah, some of these dudes are very mis-informed...... a tuned port sucks. thats why they made the super ram set-up. i understand people work with what they have, but lets face it, carb vs. fuel injection----bottm line-------beter fuel economy and cold starts with f.i. compared to cheap and infinate tunability with a carb...that is left to those who ARE NOT afraid to get our hands dirty!!!!!!!!
u got that right, i have a super victor for lsx carb version
it looks killer, can also be machined for the injctors
i was quoted 100$ from local (beck)

And yes I expect to be called a wuss for it, but at least I can work on my own car. I just prefer to show up and race, and not have to get dirty at the track.
An LS1 already makes great power, and with some tuning tools you have infinite adjustment from the driver's seat. Why go backwards and slap a carb on it and lose that ability? Plus you have to get your hands dirty every time you change fuel or timing. No thank you. I got my hands dirty enough when I installed the engine, I dont need them dirty when I'm racing the car, too.

well, i used to think like that also
but the first time out the gate with a carbed lsx a 3rd gen camaro went 10.40 with 9 in rear, and nothing more than apower valve and secondary jet changes
using stock heads, and hyper piston 6.0 engine.
it was a out of the box HP 750 double pumper that i got for 450$ brand new
roughly what a tune costs, using a victor jr. with HVH super sucker spacer.
i built the motor from oil pan to intake. only part i didnt do was the machining.
but i did provide the machine shop with the specs i needed
the fuel system cost less than 700$ including lines, fpr, and carb
u should look into it when u decide to upgrade your third gen.
never called u a wuss, just said u were misinformed
A) I live in Cali, we cant go backwards in techology because of Federal emissions laws, nor would I want to.
B) If you already have a TPI, then there is no messing with the harness if you keep the TPI. But you would have to mess with it to remove some stuff to run a carb. Some people cant tune a carb nor an EFI, so it makes no difference to them. You'd have to swap the intake no matter which system you run, and the TPI parts arent more expensive than an intake manifold, carburetor, regulator, distributor, etc.
