71 240 w/ stroked 383 LT1 and Procharger D1

[Guest Anonymous]

Just took some quick pictures with my digicam of a guys 240z. The procharger is not on it in the pics because it blew up. It has been sent back and they are sending him a D1 which will utilize a 15psi pulley. This car is incredibly fast and hangs turns like there is no tomorrow. I posted the pics on a site of mine. Unfortunatley the owner does not have internet access so won't be able to comment on any of his creation. Hopefully you guys will like these pics, enjoy.

Incredible! I love it. I'd love to know more about how he put the Procharger on, what if any intercooler, etc. Any body know from looking what kind of induction setup (brand, model) that is?

 

Thanks, Cahant for posting those pics!

 

Could you get your buddy to do a write-up of the cars parts, specs, etc. to put on your site?

The socket head screws in the strut towers-they the reason for the great handling? What is all that?

[Guest RyalC]

The "socket head screws in the strut towers" look suspiciously like the Ground Control caster/camber plates I am using. The tops of the struts even look like Tokicos I'm curious about the valve covers (LT1s are center-bolt), what the heck the line from the fuel cross over (in the center of the manifold) is used for, and what programming he is using to control the computer in that beast.

 

It looks like your buddy has solved most of the issues I am starting to hit putting the LT1 into a 240Z. If he is online I would like to "chat"

[Guest Anonymous]

Yes there was/is an intercooler. I am going to try to get him to do a write-up of all the parts so I can post it on the little quick site I made of it. Pictures don't do this car justice. It looks sooooo sweet when those 17" HRE's are rolling. Breathtaking I tell ya!

[BLKMGK]

REALLY appreciate the pics - he's got one of th eguage packages I've been considering - including the tach!

 

I'd like to know what heads he's running too. Those valve covers are awesome but I think he had to weld the filler in as I think they come "blank" from GM. Very nice look! Any details on the induction would be helpful as lot's of us would like EFI.

 

Would liek to know details on the suspensionwheelstires. Can't quite make out what size tires he's running but the package looks very nice. Is he running coilovers? Can you tell us the spring rates?

 

Seriously, there's lot's there to like and to learn about and I for one appreciate you telling us about it. Just the guage pics alone made my day!

 

Thanks!

Is he using the ATI three row? If so how did he get it to fit? If another brand, which? D1 is physically same size as the P600B. Higher max RPM 65,000! How much more does it flow? Edelbrock FI? Get this guy over to a keyboard and fill us in. You've stirred up a lot of interest here.

I'm not sure the D series is the same size as the P600. I've got a P1200 and it's about the same size but guys running the new D series have found that it mounts further off to the side. In one case, a 351W Ford in a Mustang, the guy had to cut sheet metal to squeeze it in. You don't have to do that with a P600 or P1200. BTW - some of the newer D series are MASSIVE. 20+lbs of boost on a V8 is pretty sick Damn things are pretty noisy too. Anyone interested in seeing pics of the various ProChargers? Not on Zs but I can take some of my Mustang's blower, one of the really big ones, and one on a mod motor Cobra pushing close to 500hp...

[Guest Frank280z]

Awesome Car. Love it!!! I guess he's using coilovers? to fit those HREs?? If not; what's the backspacing ane tire size?

I currently own a 98 mod-motor Cobra and plan on putting down about 420rwhp via a Vortech S-trim . I am not particularly fond of ATI's build quality but I guess they seem to work. The fact that his previous ATI blower which had no more than 3,000 miles on it "blew" up frightens me. ATI didn't even want to give him a new one or reapair it, they gave him a "discount" on the D1. He ended up paying $2200 on the D1 which is supposed to be capable of 25lbs of boost. I wonder if he knows that the D1 is physically bigger than the P600/1200. I'll have to let him know that. What a waste of money if it didn't fit. I guess ATI told him that the P1200 (I think) was capable of 15psi when it wasn't, obviously. All he said before it blew was that it was "CRAZY, INSANE, undescribable fast" can you imagine that much power with that small/light of a car?! I can't wait to go for a ride with the D1 on. I'm estimating a 383 w/ 15psi @ about at least 500rwhp. Well the only limiting factor I can see to all this is the relatively stock heads. He has plans (very shortly) for some tricked out AREs, we'll see.

 

---- For the record, the ONLY reason why I estimated AROUND 500rwhp is due to the stock heads/cam configuration that it is in now. I would say somewhere in the 500s, perhaps 550rwhp which equates to 630HP is not being too conservative. Possibly more, this is just an observation and I am in no way limiting this motors abillity make more HP. Hell it could make 700HP for all I know..but from the data I've seen at camaroz28 and other sites this is typical. Either way with a car this light it is insanely fast and almost unbeatable on the street!

I wouldn't put a whole product line down on one incident. If Prochargers were shelling left and right then you would have an argument. Granted they're not putting a lot of effort into making them pretty. I seriously wonder if there wasn't a problem with the individual unit or his installation. 15 psi should have been nothing for a 600B. (Unless he had the straight P600. If he over reved the thing then that would explain it too.) Was it a Billet impeller? I'd like to hear more facts about what happened to this unit.

Another Question: How much is a Vortech S trim? How much boost is it capable of? Just curious.

Agreed. To date I've seen problems with two Prochargers - one an early D series and the other my blower that was raced with a cog. The early D series blower turned out to have a defect and it was replaced no problems. It helps that all of this is being done through a dealer and not one on one with ATI I guess.

 

As for boost - please bear in mind what exactly boost is a measurement of. It's a measurement of intake restriction - nothing more. The idea is to move CFM into an engine. I have with my own eyes seen what happens to boost levels on a BLOWER when intake restriction falls off. I had a new intake and severely ported heads added to a Mustang that had been running a Paxton with about 8lbs of boost. Boost instantly fell to about 5PSI and that only at max RPM. However the CFM was the SAME and the car was FASTER! If this had been done on a turbo car the wastegate would've kept the boost the same and power would REALLY have picked up.

 

A P1200 moves enough air to make boost on an unloaded engine. For a centrifigal blower I found this pretty darned impressive. The car my P1200 came out of was dangerous on the street simply because it would pull the wheels and steering control would be lost! Can you say drivetrain breakage?

 

If you think 15lbs of boost will get you 500hp out of a 383 you're nutz! Try closer to 650+ with good heads and exhaust The builder who's doing my 351W claims it'll make 600-650hp with 10lbs of boost based on engines he's done with the same heads, pistons, and cam. My intake on that car will be the restrictor.

 

yeah, I think it's time I got the blown 351W finished and on the street. I'm dying to know if the HP claims are valid - I'm hoping the power is lower to be honest as that much power on a stock crankblock is close to the max it'll handle.

 

P.S. I forgot to mention - ATI came out with a NEw blower! This sucker has NO oil return or pressurized oiling. No more hole in the oil pan ala the old Paxton - schweet! My friend's shop has sold 4 kits so far but none have been installed yet. I'm going to wait and see how those cars do before I get too excited about these

[John Scott]

Amen! BLKMGK, I had a friend who kept cranking down on his wastegate until he was pushing 20+ No improvement in performance! Some superchargers are not able to push a certain CFM. Boost #s are only a poor reference of potential power. A roots blower can make tons of boost, but mostly its just expanded air due to the terrible adiabatic efficiency of the units. Can you say race gas! Just like denser intercooled boost will be a lower # but produce higher hp. A good flowing engine will do the same. ATI is suprised my boost #s are lower than, lets say a 4.6 mustang, with the same drives. Head work, Proflow valves, big cam, etc. allow me to use up more boost. Mine makes boost unloaded. How much are you talking @ what rpm? Now... about those 4.3 Brodix heads and crossram! BTW you are in for one hell of a ride with that 351! Looking for passengers?

[BLKMGK]

I honestly don't recall the numbers but I think it was over 5lbs. I just recall being stunned becasue the same sort of throttle blip on my Paxton car used to do nothing but goto zero vaccum.

 

As for the 351W - we'll see. I know the guy who specced the motor is reliable but 600+hp is a ton and I've never driven anything over say 450hp. It's actually been awhile since I've driven anything with more than 300hp so my first times driving it will be tenative at best. You don't just jump into that kind of power and expect to live - a fact I proved a couple of times letting friends drive the car with the turboes, it got hairy a few times (lol).

 

I remember how the car used to pick up power as the weather got cooler. It wold go from fairly quick to downright scary when it got cold out. 3rd gear rolling I could fry the tires on cool evenings but not during the day usually. Never took that car past 10psi but still have the manifolds in the garage for a future project.

 

BTW - just spotted a 5.0 article on the T56 in a Mustang. I'm almost wishing I'd gone Ford power with this car - almost. I could've had a 351W pretty easily and a blower real fast afterwards. I hope the Chevy motor runs as well as Keith Craft says it will - 450-600hp. I'm hoping this car won't beat the Mustang!

I got a chance to see this Z at Motorsports SHOW on 4-25-99. There's a couple of things that weren't mentioned.

First the Z had a nos bottle in the back hatch when I saw it.

And second he had the complete Arizona Z car tubular a-arms and wildwood brake assemblies.

That Z was BAD ASS !!! BLACK,BLOWN,GASSED and INJECTED damn.

I've got 3 dated pics of it, but unfortunately they don't show much more than what you've already seen.

Icouldn't get close enough too take a pic of the blower the Z was mobbed.

And didn't take a pic of the nos because I knew my crappy camera would just pick up the glare of the rear glass.

Was hoping to see it at the SHOW this year but know such luck. I'll e-mail the pics too Cahant to do with as he pleases.

I believe in thinking of the effects of typing your thoughts before doing so. Sometimes you end up making yourself look bad. Not a shot at anyone just a good rule to use when you can,t delete what you have posted. Tact and the ability to bite your lip are important assets sometimes. I strive for these myself. Just trying to be helpful.

I took the time to take some pics, thumbnail and upload so that interested forum members could see the beauty of this car and these are the kind of responses I get.

 

Does anyone on this forum actually think I am trying to criticize or under rate this car in any way? If that is what you got from my postings I sincerely apologize. In no way did I intend to do so. Getting flamed for doing nice things just doesn't add up. I'll take the pics down now so I won't have to hear anymore of this nonsense.

Hey Cahant I see no reason to take down the

pictures. I am shure that every body here

will agree. We pride ourselves in the way

we conduct our selves and the way the forums

are run. slo50h is out of line, we are not a

group that will put up with personal attacks.

There may be a time and place for what he did

but it is not here.

Wow, this went downhill fast?! Guy said he didn't like ATI and planned a Vortech for his car - where's the slam?

 

FWIW - my friend just moved up to one of the D series on his Cobra - it's a 98 too I think. Drove it just a little while and proceeded to yank the motor out! I asked him why he did this as it was running REALLY good from I'd been told. He said it was making os much power that he was afraid something was going to let go if he didn't pull it out and put good rods and pistons in it! This guy works on Mustangs 6days a week and is one of the only ProCharger dealers in VA - if he's making so much power that he's afraid the stock stuff can't handle it I'd say he's doing somehting right He was estimating in the 400s HP wise before - I can't imagine what it's doing now. Swapping a T56 too and says it was cake to do...
