36's OR 42's/ Opions?

[93BlkCobra]

Well I have both sets, I have thought to upgrade the 24's
so I can run a good amount of timming More safley.
(and kinda wonder if the sock MAF is really all that restrictive?)

Anyways, Getting ready to send off the Pro-M to be Recaled.
Im thinking either way I do it it should work well. with the 36's
thinking I will still have to run the FMU to be safe? Maybe not?
With the 42's I know we can get a better tune with out the FMU.

I plan not to get any coustom tunning right away, so I worrie
with the 42's beacuse some get lucky some don't! ( Driveabilty)

What do you guys think, Hows your Cobra run with Bigger Injectors. Thanks!

If you are making less than 400 RWHP stick with the 36's, if you are making (or plan to make) more than 400 RWHP go up to the 42's. I have modified 42's that flow 72 #, but before they were modded they caused some hard starts and needed very low pressure on motor (425 RWHP).

Whichever ones you run, get the smallest possible for your combo. Also, since you aren't going to have any tuning, I would not recommend running without your fmu, unless you verify your a/f at WOT with a wideband/dyno - you run the serious risk of getting lean in a hurry with your blower on there.

You wont need an FMU with the 36ers. They can be pushed well past 400rwhp. Go with the 36ers and put it on a dyno just to be safe. You dont have to tune but you should check A/F ratio.

I'm runnin at about 435 to 440 at the crank and using 42's with an 80mm MAF...Works great...And with 42's,you can chunk the FMU to boot...Just make sure you have an adequate pump...I'm runnin a 190 Walbro in tank pump...
