StealthRam MPFI or SuperRam??
Hey,
I have been looking around at after market EFI kits and I think these are some of the best I can find for a high proformance daily driver. I plan on using a blower.
Could you give me any input on what you think about them, or even you know of something better,
thanks

Are you doing this before or after the 6-speed, abs, suicide doors, and backwards hood?
In any event, if you're going to use a blower, I'd use something with a smaller plenum volume than the SR, because the less air that you have to pressurize, the more ATMs of pressure you'll have in the cyllinders. Actually, when you're using forced induction, I'm not sure how much advantage (if any) you'll see over a good old LTR setup.

You forgot the tube frame front clip
:lala: :lala: :lala: :lala:
I am just throwing out what I am thinking. Chances of me doing everything is very slim but I still have questions
thanks for your subport

I desided not do to the abs, even if I did have the money
I thought ABS always improoved your braking but someone said it did not so, I'll take their word for it and like the dream go
thanks again

ABS really just pulsates your breaks, when you press the petal down hard.
It makes straight line breaking increase a bit, but the idea behind it is that instead of pads contacting the rotor, and staying there, locking up the wheels, if the pads pulsate (grab and let go quickly) you will have more controll over the car, so you can steer out of the way of whatever it is you might hit, or avoid what you were breaking for.
Still, ive heard of studies done on them, and when people are almost in accidents with ABS, and they hit the petal hard (activating it) it feels like the petal is bumping and moving, some say, "like it's going over gravel" and end up taking their foot off the break, thinking the brakes are failing, and then causing an accident!
Just my opinion on what I have hears about ABS.

Yeah I understand it.
I know they were putting abs on some forumla (cart) cars and they were saying it shortened their braking distance by like 20 feet.
I thought it worked by applying as must pressure has it could with out locking the wheel and the letting go and basically repeating that. I am probably wrong though.
Thanks for your input, I think you are correct

PS_ get bigger tires
it'll reduce braking distance. You could try a parachute

oh, =)
well, I don't think my car will ever way that much =(
I have thought would putting fatter tires on it but I probably won't do that until I have at least started the engine work. I
don't even have a block right now, and I am changing my mind alot. Not sure what alot of things.
I still would really like to do the tube front clip with fiber glass everything and a roll cage
but don't hold it against me, for now it is just a thought.

Thanks everyone :hail: :hail: :hail:

wondering...
Has anyone seen a EFI system with two different sets of injectors like 24 lb and 36??
So that a person can press a button to activate the 36 lb system for racing or whatever??
thanks,
it is just a thought..

trux, if your efi system is set up properly, it will not make a difference if you had #10 injectors or #100 injectors. You can set it to open the injectors a certain pulse width for a given load condition on the engine. The ECM does not know the difference between a #24 or #30 injector. You can tell it that in the setup but ultimiatley, it is how you tune the curves that make up how the car runs.
Your stock ECM can do things like this with a custom PROM and someone with the know how setting it up for you or you can go the aftermarket route and purchase something with more control via a laptop computer.
Just a little FYI for you.

ok, cool =)
Thanks,
I really did not know that, really. I just though that it made the injector open up all teh way with a pulse and when you press the gas pedal and more air wold go in so the pulses would be increased until the a senor told it when it would burning just right.
thanks, =)
