need some input form you guys.

wanting to do a 454 build wiht 800 horse being max goal. so we were going to use a D1sc on top of motor to make up the difference. small boost. like 8-10 tops.

a few people have told me the the d1 wont allow enough air for the motor. and i should go to a f1. but if i go to a f1, i will be temeted to push the power higher.

so what do you guys think.

454 with f1 and 800 horse

or

427 with d1 and 800 horse

thanks

I'm doing a similar build but trying to maximize the larger ci. For your app I wouldn't recommend anything below an F1R. You would be winding the D1 out pretty hard=high intake temps and more SC wear to make the 800rw. With a bigger unit, it won't be breaking a sweat at 800rw=lower intake temps, lower blower speed/less wear, and less psi to make 800rw.

I'm doing a tall deck LSX 461 w/F2 going for 1500rw...

I think you should do 427+F1..800 rwhp with be easy for the motor and you wont have to spin the F1 hard. And if you get bored at 800rwhp or get curious, you can allways get more!

427 with f1C will easily meet your goals and still give you some room to up it when you get used to the power level and decide you want more.... which you will decide you want more.

Iagree plus if you want to go more you will have it and for the diff in price on the front end, If you ever want to sell will get more of your money back. The YSI unit from A/A will or do excellent also.

my vote for 427 and a f1-c as well...

The F-1C/F-1R require making mods to allow room for the head unit. As I mentioned to you in the pm's , I'd go with an F-1A for the power level you are looking for. It won't be working as hard as the D-1SC, and you'll be happy with it. Bob

the F1R is always a good choice, more $$$$, but you have the option of a cog drive, or man idler with a serp. and the thicker brackets
not sure what mod needs to be done, i have run D1SC's and F1's and F2's on BB's, only remember cutting the corner of a tall V/C for clearance-Bob, Chim in on that-i have an F1A in a box for another BB sitting around
454 or 427, not that much diff as far as supercharger choice
a while back i had an F1R on a 489, cog drive, but ran a man w/p, alt, p/s and had a mech clutch fan-used some stuff from Jones Perf in PA
the cog pulley doesnt have a front acces pulley, so you use a mandrel off the front with spacers, and a little fabbin on the rest

The F-1A fits without having to run a narrower radiator, or modify the angle of the radiator. The F-1C/F-1R will require the above mods to allow room for it to fit. For someone looking for 800 to 900 rwhp, the F-1A is the way I would go. Bob

so sorry about my lack of knowlegde. but in the f1 world. the A is least power, then C than R. is this correct?

Least amount of hassle to obtain your goals is a F1A as Bob, and others, stated. If you want get into alot of other headache then go bigger, but in a F-Body chassis the easiest install is a F1A, or D1SC. I would think the D1SC could get you your 800RWHP on an engine of that size, it be maxxed, but could probably do it, the F1A would be a better candidate to guarantee 800RWHP. Heck, LS1 347's can do 750 to the tire. don't overthink it or get sucked into the web forums, do what works and keep it simple, you'll have more time to enjoy it then chasing problems all around the car. Just my 2 cents.

i unerstand what you and everyone one else is saying.

but customer wants 800. so building that motor is easy. but with F! he can get 100 by just changing pully. he doesnt want to go that much. he has a vete that is getting those power levels.

this is why i thought of a low boost motor. he wanted the 454. i can probly talk him into the 427. just still dont want to run a lot of boost.

can you guys explain this procharger stuff a little better. how is the head uinit maxed out. i have talked to Procharger direct and they say they have cars with the d1 that maxes it out at 750 and others that max it out at 1000. so what determains this? air flow? psi?

i am so used to aturbo that this super stuff sucks. take a 454 with 8 psi and 10:1 compression on turbo and i got the 750-800 range easy.

To clarify, are you talking RWHP or WHP?? No way a D1 is making 1000 for either designation. Bob of brutespeed would be the best guy to get in contact with. He has seen a ton of these and is the expert here.

iTrader: (7)

which i did contact him.

and Prochager. a tech from there said with the right stuff a D1 would support 1000 wheel horse.

i think i might just have to make usre the customer understand what is going on.

Bob PM me a price on the kit with the F1 a

thanks for the info bob.

so what is wrong witht he normal F1. why not use it instead of the F1-a?

Bob@BruteSpeed

iTrader: (16)

You're welcome, the F-1 and F-1A are both the same price. The F-1A puts out 125 cfm more than the F-1. Since the F-1A became available I haven't sold a single F-1. Bob
