Cant wait till next season !!! I have not decided what one yet but it wont be a 2 or 3 series, so street worthyness will not be effected....

1970 1/2 RS Z28 S.B., Pump Gas, Radials, Full Tails ( 3 1/2" ) 10.59 @ 129

My buddy just jumped on the D series....lol....for his 540 http://www.nastyz28.com/ubb/smile.gif Had to order new rods and pistons to hold the HP and lower the compression. Ought to be WELL into the low 8's with that....was in the 9's a 150 shot in it http://www.nastyz28.com/ubb/smile.gif

Thats just not fair http://www.nastyz28.com/ubb/wink.gif
Now you have to get that car leagle to go that fast! I'd already be scared *witless* to be going 130mph with no cage!

Did you see the Nova that they showed off at Super Chevy last year? Ran a low 12 on the engine. Then they slapped a Pro Charger on it & went 8.XX at 160mph...wow!! I'm sure it was built just for that, but still, it gained some serious power.

------------------
11.74@118mph in full street trim, driven to the track every time! Trailers are for boats..

I still am not sure what one I want yet, lower end components are in the back of my mind... I cant see the nodular crank and pink rods holding up to the blower AND the nitrous, at least not too many times...
AS far as the safety items, they are on the list too... Cage first, net and new belts of course, I plan a brake upgrade as well (at least rear discs) After all this I hope I need a chute !!!

The "little" one might just surprise you. Even if it takes "just" a second off your time, your flying!

I'm looking hard at the one Super Chevy used on the little 383 in last months issue... I think I could live with 720-750 h.p.- BEFORE the bottle !!! Info from ATI is on the way, this should help me make my mind up.....

Oh ya ! The Super Chevy/Pro Charger test Nova, how about 4 seconds and 50 mph !!!!!!!

<font face="Arial,Verdana" size="2">BBC, 8.1 compression, Cast Iron heads, Single 850cfm carb. F2 Procharger on PUMP GAS !!!!! 1700 HP

This engine is a 580 cube BBC Iron eagle heads full ported by us. My design HYD roller cam yes HYD ROLLER. Actually 8.5 to one. Uses a procharger water to air intercooler blowing thru a single 850 carb heavily modified. I have been developing this engine package for racers and street cars. I have them in a 540 cube 1000 HP engine no intercooler on 92 octane/ a 1200 HP 572 no intercooler on 92 octane/ a 1400 HP 572 intercooled on 92 octane/ and a 1600 HP 572 ntercooled on 92 octane. I am currently developing a Dominator carb and building our own carb hat. The best thing is any of these can be run on race gas but not needed, and you just race these!! Pack the chute and put it back in staging or sit in your chair whatching others lash valves, change bottles, and all that other crud.
By the way the 1000 HP sells for $18,900.00 complete minus fuel pump, and the 1600 HP sells for only $26,000.00
My 580 (30 over 572) makes 1714 at 6500 RPM and 1420 TQ at 5500 rmp. All these engines have Low RPM big power and you can drive them to the track if you want to.

Working on the Fastest pump gas car in the nation, 93 Caprice station wagon on 10.5's 8.50's or faster is the goal</font>

from another board. how is this for making some HP?

Bob

Steve builds some nice stuff thats for sure, but nothing you or I couldnt build ourselves, given enough funds and time....
The info came on the ProChargers, this has helped me make my choice.... I will be running a D1-SC heilixed unit.... I need to do some more homework however, plans are/were not to run a intercooler at least at first, because of packageing and cost... My question for the day is, will I need to utilize a blow off valve if I dont use an intercooler ????? The intercooler option is a substantial cost running around $1,200 extra. This option package includes a blow off valve. Is the blow off protecting the intercooler ????

No the BOV is to protect the seals in your carb as well as the blower its self. when the motor is spinning up in the R's & the blower is making boost & you close the throttle all that boost has to go somewhere. it bottlenecks up between the output of the blower & the closed throttle blades & the air has to go somewhere. my understanding is that its also hard on the blower. its spinning hard & then to all of a sudden shut the outlet of the blower, hammers on the gears in the blower & back through to the belt on the front side of it.

if you are going blow through & depending on how much boost you are going to make with how much static CR, you might not need an IC @ all. Jody would probably have a better recomendation than I. he has built quite a few of these motors.

What is your HP goal? I ran a D1SC without intercooling on 91 octane on both a 468 and a 540. It made 828 rwhp (on seven cylinders it turned out, plug wire off and the new owner didn't notice!).

If I was doing it again I'd be using the F1, at least at that HP range. I highly recommend ceramic barrier coating on at least the pistons, with the combustion chamber valves helpful also. I also used a water injection kit for a safety factor, but had it tuned to not detonate without it.

You will want to run a surge valve. Like Bob said it's very hard on the impeller to snap the throttle shut after full boost. Plus many manual trans cars have a slight tuning issue going through the gears that disappears after installing one.

I have posted this info several times, so you may have seen it already, but in case you haven't...

1. I see you are running a SB, but check blower to hood clearance. I am running a BB with a P1-SC (which came with the same mounting bracket as the D series) and I had to cut hood to clear the blower housing. You can see pics @ http://photobucket.com/albums/v376/Privateer_Racing/

2. Neither the Saginaw or Jayco style power steering pump will fit. I am in the process of converting to electric power steering.

3. You will have to notch out your inner fender for blower housing clearance. Jody had to do this with his 69 as well.

Again, since you are running a SB, numbers 1 & 2 may not apply but if they are important to you, make sure to double check.

Good points Jim. I didn't realize his was a small block.

I had the 700 rwhp 406 that's in my friends 69 in my 72 at one time. It did require trimming the inner fenderwell, but it did not hit the stock hood on a small block application. Close, but cleared. The Jaco pump worked for me on the 72.

Thanks, guys ! I guess I will run a BOV, this is only a $195.00 option.... The IC will have to wait due to the cost factor, but will be added down the road.. (after I can spend some $ on the lower end, i.e. crank,rods,splayed mains)
As is, the car makes just over 600 RWHP, with 150 h.p. of hose. I hope to surpass this # by at least 100 h.p.
Hood clearence is not an issue, with the combo of the super victor and the stock dual snorkal air cleaner I need a cowl hood anyway. I had spacers between the hood and hinges for a while, but this effected the latch operation too much so now the dual snorkal is poking through the hood...
Anyway, I thought about stepping up to the competition carb hat, I know for sure I dont want their "low profile" unit, I dont like the looks of that thing at all...
If all goes well with my recovory from the nasty divorce I am going through, look out come mid summer next season, I will either go really fast or make lots of shrapnell....

my understanding is that the Extreme Velocity & CSU hats are the best & that the procharger hats are junk.

And once again Bob is correct! Do not use the ProCharger hat. If this is EFI it's not so bad, but they're horrible on a carb blow through.

What is bad about the Procharger carb hat? Is it just a bad design? What about the Vortech carb "box", that pressurizes the whole carb? Is that better than a carb hat? Reason I ask is that I have a Vortech 8 psi supercharger sitting in a box that I bought to use on "something" http://www.nastyz28.com/ubb/biggrin.gif Would the hat be better or the box, for a carb?

if you are doing a blow through application, you get back distribution through the carb. simply put its a bad design. they designed it to fit under hoods not to flow well.

the enclosures work well, but are a bitch to tune & my understanding is that they have an upper end limit as well (as far as boost/HP).

for the cost of a new hat & what you can sell the old one for on E-Bay, its worth the money to buy a new one.

Mind you this is my opinion, based on folks that have actually built these blow through motors, I have not put mine onto the car yet, its still sitting in the box on my garage floor collecting dust.

Bob

I can see where the "low profile" hat that comes with some kits would suck. I am not concerned with hood clearence issues, so the standard hat will be my choice... The competition hat looks like it would work fine, its just WAY more money... I am already speding $3000.00 on a $3.00 budget...

Well amazingly the low profile hat is MUCH better than the standard ProCharger hat. It's the standard one that has severe air flow issues. Not that it's restrictive, it's the way it makes the air enter the carb. It is bad enough that often only 1 or 2 boosters are actually doing all the work, and jetting changes make little difference. I highly recommend avoiding the standard hat if possible. It is not a complete failure, it worked okay for my friend, but there are far more people with trouble with that hat than any other.
