Who is running F1 Prochargers on LT1's ?

My car is almost complete, and I was just wondering who else is running F1 or F1a prochargers on an LT1. I want to know about your setup, and any times, or dyno numbers you have made.

I also was curious on what you did with the ignition system.

I will be soon :D

im going to be running a ysi, which is the closest ive seen to an f1a. I am using the delteq qith a crane trc-1 for ignition

That would be me. I know of at least 2 others running either a F1 or F1A. Bads95TA comes to mind FastBird93 (soon to be) and another TA owner from Kentucky....can't remember his name but he's on here a lot.

No times as of yet but just your typical 8:8.1, 383, 22psi, w/ all the fixings. I had to ditch the Delteq as no one could get one to work w/ a SA management system...so I'm back to a Crane HI-6R which is fine for now since I don't drive the car a lot to begin with. Check the sticky up top for the boosted and I'm on the 1st page for details.

I am just finishing up the motor. Here are a couple of pictures.
Also, I fabricated a large FMIC for the F1-A.

With regards to the ignition, I chose to run a Big Stuff 3 LS-X coil-on-plug system and eliminated the Opti-spark system all together on my LT-1.

Obviously, I don't have any dyno numbers of times yet, BUT THEY ARE COMING!!! Feel free to ask if you have any specific questions.

There are several more guys running either a "D" or "F" series Procharger that have some real nice set-ups on this forum. I'm sure they will check in as well. :D

I got my F1A on the Z last week. I made it down to the project camaro car show with it but thats about it. Im still waiting for the right length 12 rib belt. (I now have a 6 rib belt on so I can drive it).

Im running (new) Gm opti spark, with msd booster coil, msd 6 plus box. I also have my own FMIC on. (17-18 psi should be)

Wont have any new # for a while yet, still have to up grade fuel system.
Sounds unreal!!!!

Have run a F1 for 2½ season now, best time last year widh a 4" OBX FMIC making 17psi in a 3650lbs car was 9.44 (widh a 60shot N2O)
This year widhout FMIC making 20+psi running 8.5 in a new chassie.
Ign system was from the begining a MSD6al and stock coil and now a malloroy685 widh a blaster coil.

any times, or dyno numbers you have made.

Mine is NOT an LT1, it's just a 1st gen 383, 9:1, F1, air to air IC, Fast EFI, with a long cam and big heads.

Chassis dyno to 6200 rpm where it had valve float:eek: 14.6lbs boost made 712 RWHP.

I've run 137.9 MPH in the 1/4,(17# boost) but had traction problems. Best ET was 10.14@ 136.4, 1.62 60' with 15.5# boost (see vidio in sig).

On only 10 to 12 lbs boost, I was able to go 1.45 60foot, with my new adjustable clutch.

Hope that helps, oh my car is 3450#. ---Bill.

What Cam is that that 383, and how hard are you spinning that blower???

What Cam is that that 383, and how hard are you spinning that blower???

Sorry, when I wrote "long cam" I just meant it had a lot of duration. It's a Comp solid roller, 255/262* @.050 w/.613 lift, w/1.6 rockers, 114LS.
My F1 makes 17# spinning it at 66,850rpm w/ a 4" pully (12rib) at 7K engine rpm.

I'm running an F1A. Street Ported Lt1 heads with 9.0 Compression and a Comp 224/230 Cam. 15 psi through a gigantic 4" FMIC and spraying ALKY. I'm using the stock OBD2 computer and delteq radiator mount. I also have a complete tuning system with a wideband commander and tunercat. My car is a daily driver and has 30,000 hard miles on a short block that cost less than $1500.:)

Thanks for all the replies so far guys.

I can't wait to get my car back out on the street.(And the track too)

I had fun racing tonight in the 98' but got my azz handed to me a few times.

What size crank pulley? -Tim

What size crank pulley? -Tim

Tim, it's 7.65" , also my F1 only has a 5.0:1 internal step up. I could be wrong but I think the newer F1 has a 5.4:1 step up like the F1A & F1R.

As ZBLKHELLRZR mentioned, I'll be running an F1A on my new setup, pullied to put out as much as it will at about 6500-6700 RPM (read max impeller speed). Nothing cosmic, just a good bottom end and a ported TFS headed top end. Still have a LONG way to go though.

Light a fire underneath it! Get that thing going!! :D

(I'm impatient :) )

I'm trying. I'll have the old motor out and torn down on Saturday (provided the hangover isn't too bad) and once I get that parted out I'll concentrate on ordering the extras for the new motor.

I think I'm going to ditch the intercoolers and run straight Meth though. There's just no room for a good and efficient FMIC on the LT1 T/A's, the ATI twins while good, will probably cost me a bit in the boost drop area and clutter up all the pipes, so I figure why not just go straight to the intake and use meth all the time.

(sorry in advance to hijack the thread)

Keep in mind that you might be limiting yourself to only so much HP by skipping out on the intercoolers. The methanol will help, but even if you are spraying like a madman it will only help cool so much. You will have gobs of boost and power from the F1 (especially from not running an IC if thats what you choose). But while tuning it, you might be able to only run so much timing if things are getting too hot even with the methanol. I would say, stick with the twins to help things out, and then you can max out the power as I know you want to.

Man, listen to you! :D I know fully well that I may be limiting myself by not running intercoolers, but again, the twins are going to be a PITA to install, clog up the front end with piping, and aren't going to be terribly efficient. If I could use the LS1 4.5" twins I'd probably stick with them but the 3.5's aren't going to be up to the F1A task.

I am considering a horizontally mounted FMIC and cutting back the nose some on the underside, but even that is going to only be so efficient considering the airflow potential over it. I figure since the T/A front end doesn't allow for a very efficient intercooler why fight it, and shoot the injection, no intercooler, keep things simple, and don't fight it. It's going to make what it makes. I haven't decided if I'm going to go for this or no intercoolers, but right now I just don't feel like fighting the Twins.

i've been running the F1 for years in my t/a

Ehh.... fight the twins. By themselfves you are right they won't help out much, but with the meth they may be all the difference you need to max out the power. If you wanted an easy car to work on, you should know by now an LT1 is never easy :lol:

Im running air/water on my car and it works great i can send you some pics if you would want

Too much entailed for an Air/Water intercooler. Thanks though.

I'm running an F1x non-intercooled. :)

F1x?

F1x?

It's an F1 ABCD... in other words I'm not saying as of yet! :D :P

:lol: ok that works

I guess while the topic of intercoolers came up in this post.

What is everybody using, and please post some pics if possible.

That will will be one of the few remaining things I have to do.

32X12X4 IC is what I have.

How's that working out for you? Street car at all? dual nozzle injection I presume?

Working out pretty well so far. Yeah, it's still a street car for the most part. I've got about 500 miles on it so far (having time to work on it/drive it has been at a premium since my son was born 4 months ago, :lol: )

I have a 2 nozzle Snow kit.

Yeah, I could see time being a little lacking there. Have you logged the IAT's at all with the meth set up and running?? I'm curious to see how well it's working after a full throttle blast.

I don't have any data yet, haven't gone WOT. I now have IAT's about 125-130 cruising down the road in 95 degree heat though. Before I had an inlet on the blower it was running 155-160. :eek: Sucking that hot air off the headers is no good! :lol:

So that's at cruise with no boost/meth??? That's not so bad, but then again, that's one point where intercoolers would definitely show their worth. That's got me thinking now as I wonder how high that would be with the A/C running..........

Yeah, that's cruising at 70-75 mph. If I still had A/C, I doubt it would be too much higher, as the filter is stuck in about the same place it would be with a cold air intake.

I was just thinking about the extra load on the motor from the A/C.

glad to hear that as it's what I'm planning on doing for now
