Anyone wanna benchrace? Need some advice too

[DRASTiK]

Gotta opinionated question for ya. What do you think I'll be looking at E.T. wise and/or HP wise with these future (next month) modifications?

Performer RPM heads port matched to...... ****** I'm not sure which gasket it is... it's the black gaskets with the red outlines. Anyways, they're pretty big ports.

Sorry the porting details are fuzzy, that's just the info I got over the phone from my buddy in AZ who's selling the heads and cam to me. He didn't know what kind of gaskets they are and all I ever used was felpro, which these definately aren't.

Systemax II upper and lower (matched to heads)
X-cam with matching springs on heads
Crane 1.6 RR's

Which TB 65 or 70?
Will I need 24lbers?
Will an adjustable FPR be necessary?
The rest of my setup is in my sig.
Am I forgetting anything?

Any thoughts will be appreciated. This is my first EFI project, so I wanna do it right the first time. I've done the carb thing a few times, but I'm not sure about some of the EFI stuff so I figured I'd ask you all who've done this before.

I'd say you'll be lookin at somewhere about 300rwhp. Which with some good tires and driving could have you in the mid-low 12's.

I'd skip the 65 and go with a 70mm TB.
You won't NEED 24lb injectors but if you stay with 19's then you'll have to have your fuel pressure way up there.
I've heard that people have tuning problems with 24lb'ers so I'd skip those as well and grab some 30's

good luck with it

Thanks for the reply. You don't think that 30lbers would be a little too big? I have no plans in the future for a power adder at this time. As far as suspension and frame support, I'm hopefully getting some full length subframe connectors made (using that writeup by Chris Neighbors on the Corral), but other than that, what needs to be done. I'm trying to put together a plan for the car so that my wife understands and she says that as long as I stick to my plans then I can get the parts listed when funds allow it. Mainly I am shooting for a Drag Radial setup, but I don't want to be snapping any axles. Is this something I should be worried about now? I know that anything can break at the track, but should I be seriously looking at some 31 splines? What about suspension. It's a daily driver and cornering isn't really an issue, just drag racing at the track mostly and if challenged on the street. I definately need to keep this car for a long time and it will continue to be my daily driver unless I win the lotto or something like that. Lemme know what you guys think please.

As long as you keep the fuel pressure down, the 30lb'ers wont be to big. Its MUCH better to be running a little rich compared to pulling your hair out worrying if its gonna blow up because its too lean.

I think a good set of 28 spline axle's would suit you fine unless you plan on running slicks alot then it would be iffy. This way all you'd have to do is slip the axles in and wouldnt have to change out the diff.

Hey buddy, what's new? Do you think you will have all that done by the time I get back? I hope so, I can' t wait to get back and go cruzin' around. I'm still up in the air about what I am going to do with my car. I think I will just stick to the original plan of nitrous. That will leave me more money to put in other areas. Besides, it's going to be plenty fast on motor alone. How are things back on base? Well, I'll talk at ya later. -Chris

Byrne, check your 15meu email.

Any more opinions? agree/disagree?

[DRASTiK]

If I were to go 30's what fp would be okay, I know it'd be kinda low, but about how low? What about 24's, where would the fp be then? How high could I crank the 19's to be in the safe zone? I know there's no certain number answer, but a guestimate is better than nothing.

[bags50lx]

24# will fine for your setup and fuel pressure should be right around stock setting.30# will be too big.

[fiveohpatrol]

I don't know the right fuel pressure settings because I haven't tried 30's or even 24's myself. But I'd guess you'd have to crank the pressure up to about 48-49 psi with 19 lb'ers.

Why do people respond to questions with an answer that they don't try to explain? I think its because they heard that somewhere and automatically praise it as the truth that can't be bent. Why exactly would the 30lb injectors be to big? if you turn the pressure down, the 30's will be fine. This way you won't run into any drivability problems with the 24's either.
There isn't a set graph to go by to tell you exactly what injectors you need. I know that 19s are supposed to be good up to 350hp. So does that mean that at 349 your 19's are fine and then at 351 they're not? No. There is an overlap, and I believe you will find yourself in an overlap that the 24's AND the 30's will be fine. Plus IF you do decide to go with nitrous or a blower eventually, then you'll be much better off with the 30's. IMO the 24's for any car are a waste of time/money.

[DRASTiK]

I think I'm going to go with 24's and 70mm tb. Hopefully I won't have too many problems with it. Thanks for your help.

Dave, don't forget that you must change the calibration tube in the mass air meter if you plan to upgrade to 24lbers!, They say that the cobra computer with the meter and injectors is the "perfect tune" for the 24's. Good luck, be sure to posts some times with the new setup. Good Luck, and yes I will give mine when i run it here in texas.
