I need some advice from forum goers, and I have spent a considerable amount of time to find no real answers.

First, my HP goals:
800+ rwhp, as close to the 850 rwhp mark as possible.

Limitations: I want it to run on pump gas, and the best octane out here in Arizona is 91 ()

Engine: forged LQ9 based 408, AFR 225 heads (looking at ~9:1 compression ratio).

Initially, I wanted to do a single turbo setup, and I spent a while researching turbos and their components, but the amount of installation work needed to get them into the car and running was a little bit of a turnoff. I'm moderately mechanically inclined, but I am looking at the FI build as more of a learning experience.

Then I started looking at prochargers, and the F1A really caught my eye. I haven't seen much on install literature for it, but I have seen numerous places that said it was a breeze to put in. Any estimates on what I would have to push boost wise through an F1a to hit my rwhp goals? Also, any insight on installation of an F1a system in an fbody? I know the D1SC can get some nice numbers out of it, but it seems that the F1a would have an easier time and hold up longer?

Thanks guys.

 

E85 is pump gas

 

I would guess 17.5 psi to hit 850 depending on the motor specs and the rest of the system.

Have you also looked into the F2 series? theres one in the classifieds right now for a good price

 

An F2 would need a good amount of costum work done in order to make it fit. But I know that an F1c or F1r should get you there with about 18psi. I don't know if this is still for sale but there is a member on this site who is selling his F1C setup (i think) with a costum FMIC and a fully refreshed head unit. I think his name on here is Jimmy P but I don't know if he sold it. If I was going to run a Procharge kit, his would be the one hands down.

 

Thanks for the replies guys. I am not very interested in the f2 system, and if I can avoid the f1c I will. I was just looking to see how much I'm going to build this motor up to handle the stress. As a side note, I have not seen very many fbody cars running this system. I know there are a few, but even typing f1a into the search up top doesn't yield much.

 

There is a good amount of guys running the f1a, I was going to run it also but went with a diff. route. Look up lmt0705 just to give you a better idea, or EPP's website has pictures and builds of their red Camaro with an F1a I think.

 

F1A is a bit bigger, since I run an aftermarket radiator there wasn't a lot of room for the pos inlet hat that ATI sends with them, after ditching the AC we were able to push the radiator forward enough to get enough room to run a 4" hose right off the inlet.

You can see the difference between the F1A and D1SC here: http://www.procharger.com/models.shtml

I am running a customer tensioner setup that one of the users here sells, it is working great. I haven't been maxing the F1A out yet but that is changing soon and I hope to have some new numbers soon.

I have seen 386 strokers running the F1A and pushing around 800rwhp so I imagine you should be able to hit 850.

 

Think your goals are well within reason with the F1-A
I'm running 93 octane.... 12.4 lb boost W/methanol, 9.5 c/r
I'm sure it could be tuned very close to your goals using 91 octane w/meth

 

Awesome, some very reassuring posts.

Ahh yes, meth injection. I was hoping by bringing that compression ratio much closer to the ~9:1 I could sidestep having to spray meth. If it's unavoidable, then oh well, but I really want this car to be a "bring it to the gas station and go". It's one of those things that if I had to sacrifice a little timing but not have to run the methanol, I would go for it, even if I undershot my goal by up to 30 rwhp.

 

The thing is you and I live in mustang alley. Not very many insane F bodies here in az unless you venture out to the east valley. I have seen a few F1 guys out there but turbos are the thing these days. Im on the fence myself with what fuel to run. I have a station that is selling E85 right down the street but who knows how long they will offer it. I'm shooting for 1200hp with my build.

If you do go with gas, I think methanol will be manditory at your boost level. It's cheap insurance really. There are a few race shops here in phoenix that sell it fairly cheap.

 

You should want to run meth lol You'll be able to pull a lot more outta her on pump and be safer at the same time.

 

It was more the idea of me keeping a massive barrel of the stuff in my garage that made it seem more of a hassle than it probably is.

Well, if it can't be avoided, it can't be avoided. This car is not leaving the 91 octane zone.

 

I keep a 5 gallon can in my storage bin :-) lol Meth usage is proportional to the right foots usage lol. My kit kicks on a 2psi It actually lats quite awhile and I keep my right foot happy lol

 

That's another thing, is I am criminally ignorant on meth injection, but I know where I can get kits, etc.

How long would a 2 gallon capacity meth kit last me? Relatively. Maybe in terms of track passes versus tooling around town staying out of the throttle.

 

I don't really use that much meth, But it's kinda cool that I live close to the Indy 500 track and you can drive in there & buy it from the pump for about a buck and a half a gallon more than 93 octane is on the street.
When I go I Fill my 3 gallon tank and a 5 gallon can & it last me at least a month or two...... So it's not much of a hassle

 

Oh wow, that's not bad at all.

Here I was thinking I needed a 55 gallon drum of the stuff.

 

So after a call to procharger, it's becoming increasingly apparent making this supercharger cog driven is the way to go. Anybody have any input on a cog setup? I really want to keep all factory accessories, but I simply don't know enough to make any judgments.

Edit: never mind, refined my search terms a bit. Looks like I can do an SDCE tensioner or pm Aster for his custom tensioner?

 

Seems like a good idea.

 

I have aster's bracket on the way. It is awesome, gives much better belt wrap than even the SDCE. And the SDCE setup is expensive, requires your old bracket, and takes forever to get to/from. Aster's is the way to go and you can get a bigger crank pulley to max out the f1a without belt slip. PM him for the pictures you wont be disappointed

 

Will do, thanks guys. Enormous help
