Lockjaw Posted August 19, 2002 Share Posted August 19, 2002 I have some info on a Z car that is a claimed 9 second car. Here is the quote from them. The car run 9.63 @147mph. It is street driven and runs the stock computer set up. We have 4 additional injectors for additional fuel. The car dynoed to the wheels 738 HP at 24 lbs of boost. We are planning on putting on NOS to help keep up with the outlaw class. With some suspension tweaking and wider slicks we are sure the car can run low 9s. Thanks for writing. And we have never had a problem splitting the intake manifold. Hopefully Turbo magazine will picture the car in the magazine in the up coming future. __________________________________________________ I have some pictures I could email someone if they can put them out there. I don't have a wedsite to put them on. Email me and I will send them to you. These show the hogged out intake manifold, head, pictures of the engine compartment, etc. Quote Link to comment Share on other sites More sharing options...

What's up with that???? Everybody knows any boost over 20psi will split that sucker right in half...maybe he doesn't have the NAAAAAAWWWWWWWWSSSSSSSSSSSS installed right Quote Link to comment Share on other sites More sharing options...
Lockjaw Posted August 19, 2002 Author Share Posted August 19, 2002 If you could see the picture of the intake, you would know why I asked that question. Quote Link to comment Share on other sites More sharing options...
Cody 82 ZXT Posted August 19, 2002 Share Posted August 19, 2002 Lockjaw, Send me the pics. I have a place I can put them so they can be uploaded. I have to warn you it will be later tonight before I can do it though. I'd love to see the pics. Send them to me even if you send them to someone else, if you would.

Lockjaw Posted August 19, 2002 Author Share Posted August 19, 2002 You have mail. This evening will be fine with me. I would just like to see them out here to see what people say. Just remember guys, I am merely the messenger. Quote Link to comment Share on other sites More sharing options...

Bob_H Posted August 20, 2002 Share Posted August 20, 2002 Ok, so it looks the part of 700+ hp, but stock computer? Where did you get the info, from them directly or on a website? I, as many of us, would like to learn much more about this one. Of course I recognize that is why you are posting about it. And you are right, that is a seriously hogged out intake. -Bob ok, edit- I see that in their response you wrote them. I assume they are running a solid axle of some kind to keep running at those times/speeds. Yea, a lot of unknowns there that would be good to find out, like turbo size, CAM PROFILE(big one). only 24 psi and NO NOS for the RWHP rating they told you.

Lockjaw Posted August 20, 2002 Author Share Posted August 20, 2002 I have a lot of questions for them myself. My opinion on the turbo based upon the look of the compressor wheel is that it is a T series type wheel of some sort. I don't know how you could suck 700 rwhp worth of air thru the stock AFM either. Unless they have figured out how to disconnect the rev limiter, they would be pretty much stuck at about 6500 rpms, so they could not have that radical of a cam. I found the guy on Zcar.com advertising in the items for sale section. I could send them a book full of questions, and if I could see the car in person, perhaps that would help.

My opinion on the turbo based upon the look of the compressor wheel is that it is a T series type wheel of some sort. I hate to sound skeptical, but that does not look like a T-series to me. The compressor housings for the T-series are much bigger than that. I'm not able to see the last two pics, but I'm pretty sure that I see an internal wastegate actuator on the turbine housing in the fourth picture. Now, I know that I don't know everything, and there is probably more to be had, but I am having serious trouble believing that I have somehow left ~300hp on the table...

yo2001 Posted August 21, 2002 Share Posted August 21, 2002 Last 9 sec 1g Z I saw was twin KKK turbo 2.9L stroked with twm intake managed with Motec box. That I can believe. Quote Link to comment Share on other sites More sharing options...
SleeperZ Posted August 21, 2002 Share Posted August 21, 2002 That sounds like an awful lot of HP for just 24psi of boost. Seems that the redline would have to move up past 7000 rpm to get that kind of power out of a L28, and a god-awful amount of porting and camshaft work. Seems like JeffP has done much the same, and he's still putting just 400+ ( just 400hp )to the ground. I mean really...seriously...can a L series block even deal with 700hp???? Maybe I'm not doubting the power so much as the power with only 24psi...Isn't Scotty GNZ running more than that, maybe 27 psi with a MUCH bigger motor, and putting down around 500-600hp??

Lockjaw Posted August 22, 2002 Author Share Posted August 22, 2002 I have lots of questions myself. TimZ, I am sure the cars pictured and the turbo are not the ones on the 9 second car. I think those were just pictues showing thier work, and the products they have available. I would like to see the thing in turbo mag so I could get a better look at the car itself.

clint78z Posted August 22, 2002 Share Posted August 22, 2002 Mabey those are alcohol injectors, or he is using nitromethane in the tank. Pehaps a big ol bottle of NOS. That could account for another 300hp. Perhaps the whole car is gutted ?? It may be possible but I am skeptical until I see a timeslip and more info.

awd92gsx Posted August 26, 2002 Share Posted August 26, 2002 My memory is a little vague on this one, but I think I remember either John Shepard (or was it one of the Extreme guys) putting down over 700hp in a 2.0L DSM running about the same amount of boost...if a 2.0L DSM could do it, I don't see why a 2.8L L28ET couldn't do it IF the compression ratio and there was some serious head work, of course, it could be stroked, too... Of course...the L series cylinder head isn't exactly on the leading edge of technology, so it'd be pretty tough to coax that much hp out of one...

Lockjaw Posted August 26, 2002 Author Share Posted August 26, 2002 Actually the P90 turbo head is a really nice flowing head, and Nissan did alot of development work on it. Yes it is no DOHc 4 valve per cylinder crossflow head, but it works really well. Quote Link to comment Share on other sites More sharing options...
clint78z Posted August 27, 2002 Share Posted August 27, 2002 There are big differences in a 2.0l DSM and a 2.8l L28et. We have both in the family. The 2.8 is far superior off boost and has better low end. The L28 will not rev like the 2.0l, the cam just won't let it, and it would be the first to break a crank. On a full out modified race motor there are other hidden factors that limit a motor. Crank resonace limits the rpm and sometimes limits horspower.Main bearing and cap distortion limit how much power will be made before destruction Combustion chamber design is a big factor on a turbo car. The new heads can take way more boost before preigntion happens. The 2.0l DSM is a 4v head and is more effecient. How the head is bolted on limits the amount of boost that can be run.
