Here it is......all together save for intercooler and tubing (gotta build a frame for that on the dyno stand) finally...

in case anyone missed the specs, just search for recent threads in here from me, with more pics and stuff....

its an F1-R procharged, intercooled, methanol injected 383 SBC

should have it on the engine dyno in a week or two

Nice!

it doesnt look very hood friendly, will it fit?

383backinblack

it already did.....like 3 times lol........same hood clearance.....just new block, crank, rods, etc.

it has a 4.5" cowl with a special little bubble i made to fit the blower

thanks man

//<86TA>\\

iTrader: (14)

ahh, cool. I kinda figured there had to be a little bubble or something over by the blower. Im toying with the idea of getting a procharger for my 408 in the future. Should be sweet, but i guess i would have to chop up my hood as well.

383backinblack

depends which blower......if you want an f-series....definitely....and you're wheel well

Batass

Holy beefy blower bracket. What block did you go with?

iTrader: (1)

procharged iroc on you tube

383backinblack

thats what it comes with lol.......it's a dart little M

Batass

That motor is FBA!!! FBA!!! Had to say it twice. I dont know if I would have dished out the cash for the AFRs though. Maybe an RHS with a larger intake runner. Dont mean to pick your motor apart, I just wonder how much more power it would make with the AFRs over a larger inferior head with the boost.

You wouldnt want to hand out those custom cam specs would ya?

Hows that car work with that trans? Id like to get one to make driving a little more fun over my manual th350.

What tires did you run? Did you hook good? What tires for the new setup?

Sorry for the questions but Id like to get up to your power level in two years or so. Might go with a boring turbo though.....

Ferggin Bad A$$ engine man.

383backinblack

thanks man......

the afr heads have superior port velocity and mid lift flow (even the older heads like mine) than everything else out there, thats why no matter what flow numbers other companies throw out there, they always get flogged in dyno tests by AFR. as far as cost goes, i've had the heads for years......from when the car was naturally aspirated.....in fact thats about the only thing thats left from my old motor heads, intake, and oilpan

the trans works mint thus far....the cam is huge, so it wouldnt be nearly as streetable with an auto.

i dont have the card in front of me, but i believe the lift is .630/.630 and the duration is 262/272 at .050 on a 114LSA (its installed 3.5 deg advanced)

the car hooks good.....mickey thompson et streets......it had 26x12.5's on it, but now it will have 28x12.5's.......its got more to do with suspension than tires though

iTrader: (3)

Holy god of war!!! That is nice. That is a rear killer for sure...I'd be very interested to get some 1/4 passes with that. Post up times and dyno #'s once you have them.

Batass

I have 29x12.5 sportsmans on my car now. I just had to do a little beating in the well. I put stiffer springs in the rear, as I heard with an auto trans and stock suspension you want stiffer. So they dont come near the lip, but when I get her to the track and launch it...might be a different story.

Are you sure that cam is 262/272 at .050!?! Thats some wild duration.

So you just have to rig up the exchanger and its ready to dyno?

383backinblack

yup, its a good sized cam for a small block.

if your suspension works right, the rear of the car should raise up, not drop down. if its dropping, the car is trying to pull the rear tires up, and you're losing traction.....if its raising, then its pushing down which is what you want

Batass

Right. Right now the control arms are parallel. Whis is supposed to be the best place if you hook. Keeps all force going forward. If I get sloppy, then Ill get some rca brackets.

A lot of people talk about cars squatting and how good that is, couldnt be farther from the truth.

Why do you need that much duration with a blower? I didnt think you could even get that kind of duration with a lobe sep that high.

383backinblack

more duration = more air in, more air out

and yes, you can lol

Batass

Im running a xr288hr 110 lobe. I was told it would be good for me. But that was back when I was running 7-8lbs. Id like to push more like 12-14 this summer and I'm wondering if I should change the cam....

Cant wait to see those numbers man! Hey whats the benefit of running both a cooler and meth? I thought just meth was good enough.

383backinblack

ya, thats what the companies that make the methanol kits want you to think lol.......alot higher boost you need all the help you can get to keep the temperature down.

preston smith does the same thing in his turbo iroc, and after the intercooler he was seeing an additional 40-60 degree reduction in air intake temps when the methanol turned on.

TraviZ

iTrader: (2)

I run a 236/248 duration cam at 113 for my 15psi.

Batass

Interesting, at what pressure would you say both are worth the cost and work?
I wish there were some way to test a cam without trial and error.

I dont really want to hit solid 9s with my car. I dont feel like installing all the safety stuff. Well see what happens this year. Should be mid 10s. If I want to go faster, I should really upgrade my block. I have an old block thats stronger, Id probably put a solid roller in it so if I need to change my cam I'll do it then. Or maybe a 406.....if I think I can keep the traction.

383backinblack

i have no idea, its good insurance for any forced air motor......but it will definitely allow you to run more boost and more timing regardless......it will lower your intake temps regardless.

Batass

Maybe ill have to get an intake air temp sensor. I have a snap-on needle thermometer, but I dont know if it would be good enough. It would be interesting to see where I stand with just the meth.

Tbi-MAX

this is absolutely crazy in a good way..

i must ask is this port fuel injected? throttle body? carb?

383backinblack

did you miss the carburetor sitting on top of the engine?

Batass

I thought it was a TPI....a new short runner style. Just two injectors though, thats definitely not enough for that turbo you have there. And whats all that doing on a Ford block?

Tbi-MAX

duuhhh... i was so caught up with everything else... i had figure it out, but i had already posted the question... couldnt delete it.. rofl

Orr89RocZ

iTrader: (20)

looks awesome man! huge blower!!

NOt that it really matters since old afr's are still good heads and you'll make your power, but you could consider the new Eliminators from AFR... They kill the old AFR heads in all flow ranges and velocity. Just a thought down the road if your looking for a tad bit more power

383backinblack

i've thought about that since they came out.......but when you drop money on this thing in chunks of 4 digits.....the old fully cnc ported heads will have to do for now.

Batass

Have you thought about running a vacuum pump at that boost?

383backinblack

vacuum pumps suck for street cars

Batass

I thought there were some that were claimed to be ok. They didnt require as much oil or something. I was also reading about using a Ford smog? pump found on the new cars and trucks. Electric driven, so you could control it. Just need a oil separator, doesnt like oil in it I guess.

One thing I had thought about doing though was to run a hose to the end of the header, just for the track though, when I have the exhaust system off, or an open turn out installed.

TexasLT1

man I'm glad to see that bracket in action. that's pretty much what I ended up with for my F-1 on an LT1. since it's in a thirdgen, neither the 3rd gen or the 4th gen brackets would work, ended up getting a universal SBC bracket that looks pretty much exactly like what you have. mine just isn't a cog setup

383backinblack

i have exhaust powered crankcase evacuation....works fine all the time
----------
ya, its a pain in the *** to set these things up.....good luck with the serp belt lol.....hope you're not going to try and drive that blower to redline with it, it'll be doing a burnout on the pulleys

TraviZ

iTrader: (2)

My F1 is setup with a 12rib serpentine. Do you think its going to do burnouts?

383backinblack

is it an f1-R? if it is, theres no way you're going to turn it all the way to 68,000 rpm with a serp belt......thats the whole reason for the existance of the HTD/GT profile toothed setup......in order to even try it, you'd need some EVIL belt tension......i wouldnt even chance it

BADMAN

iTrader: (13)

PM sent.

TraviZ

iTrader: (2)

Nope, just an F1A

383backinblack

those have a different gear ratio don't they? the f1-r is 5.4:1

the other problem with a serp belt, is in order to turn the blower that fast, you gotta get pretty small on the blower pulley......you lose alot of contact area for the belt

TraviZ

iTrader: (2)

F1A is 5.4:1 as well

2fast4u92z

Not picking on the setup. However any reason you didn't do a reverse superchargeer setup or a remote waterpump? So the supercharge could be more inboard. Also did procharger know this was going on a 3rd gen? Cuz they give a differnt setup (blower outlet facing the driver fender). Maybe if you say carb they send it that way?!? I like it!

http://www.gilsbachracecraft.com/bil...nior/index.htm

Can't find my pics of the remote waterpump. They are nice cuz they free up a lot of room on a race car all you need is alt.,crank,and maybe vacuum pump all can run off a very small v belt. A then drop the engine lower and run the supercharger outlet tube in the car to a water/air cooler, then out to a reverse intake. Just some thoughts.

Batass

I heard the exhaust evacs dont work well with any kind of backpressure, such as mufflers. If you found this not to be true, I'm very excited!! I run a dual 3" with dynomax welded mufflers. Should be very little backpressure.

Do you run one hose off the valvecover? Or one on each side?

383backinblack

thats a small block blower bracket, there are other setups like chain drives etc that mount it the other way made by other companies but its not really necessary for an f1.....thats what procharger makes.......the f series blowers arent really application specific, the listed application is "small block chevy, race"

air/water intercoolers are pretty lame for street cars, i like to be able to have a passenger so thats out anyways......and if the blower discharge faced the fender with the bracket itd be a huge pain in the *** as it would have to run the tube THROUGH the fender to get anywhere. You're probably thinking of a reverse rotation blower.....they have those.

If you put the blower anyplace else in the engine compartment it'd be in the way honestly.......and it'd be even more difficult to route the tubing, the way that thing is setup there is only 4 major bends in the entire tubing system.......with 3 piece of tubing.
----------
i have flowtech warlock mufflers......almost no back pressure, so its not a problem they have excellent suction.

theres one on each side

Kendol

Thought I might drop some pics of my setup which is pretty close to yours.

Kendol

Some more..........

Kendol

Last pic..........

It's a 415cid SBC
Custom blower cam (Cam Motion)
AFR 210cc Eliminator cylinder heads
Hogan's custom sheetmetal intake
Direct port NOS system
Procharger F1R
F.A.S.T. XFI with complete data aquisition gear (i.e. pyros, accelerometer, etc)
Engine is complete just needs aftercooler piping.
Dyno session soon. Desperately waiting to get it into a car (preferrably Guido's old blue IROC if anyone can get him to get back with me).

TexasLT1

I should be fine for now. I'm only going to be pushing 12ish# through it for now with I believe a 4" upper pulley, probably keep engine RPM below 6500 as well. we'll see though. haha.

Batass

Whats the nitrous for lol?

383backinblack

thats awesome man.....whats the impeller speed gonna be? really nice setup, whats in the lower end?

i dunno how much experience you have with these blowers.....but the f1 pulls so much air, that air filter will cause enough of a restriction that it will eventually start to pull oil through the output shaft......happened to me 3 times in one summer. The guy that runs the shop at procharger told me "anonymously" to ditch the air filter.....its been ok since then. It's not like the car gets drive 100k miles a year in a dustbowl anyways lol.
----------
wow man.....you barely have to turn that thing to make 12psi haha.......im gonna dyno test some stuff on the engine dyno.....

its cammed to run up to 7500 rpm, after we test that if there isnt anything else that needs to get on the dyno right away, i want to pulley it WAY up and max the blower out at 6500rpm, see how much torque it'll make with all the boost coming in down low like that.......maybe it'll go quicker haha......it'll most likely make less power that way, but it might get down the track faster.

Kendol

Nitrous will act like an anti-detonant. They used to use it back in the day on high altitude, supercharged airplanes. A small (reasonable shot 50hp) will help drop air inlet temps significantly. I will be injecting methanol as the supplemental fuel. All controlled by the FAST XFI nitrous enrichment features.

Batass

Well thats something I didnt know. What do you mean by supplemental? Mixing it with the nitrous in a wet setup?

Kendol

As for the lower end:

GM CNC bowtie block (splayed 4-bolt caps across all journals {not just the center three}, siamesed cylinders, o-ringed block, blind head bolt holes, 3/4 filled with block filler)
Bore: 4.125"
Crank: Callies forged 4340, 3.875" stroke
Rods: Lunati ProMod 5.7"
Pistons: JE 26cc "dish" custom
Cam: Cam Motion custom blower spec solid roller
Timing Chain: Jesel Beltdrive
Pan: Custom fabbed aluminum by Stef's

I will get back with you on the drive ratio/impeller speed. I did all the calculations last year and I will have to dig them up when I get home. I believe it set for 24psi at 6500 with a max impeller speed of 64,000 rpm.

I agree about the air filter. I have been using an F2 on a almost stock 502BBC and I had the same thing happen with rear blower seal. I have since gone to a conical inlet with mesh screen. I suppose this engine will be no different.
