Came out from under you at 90 MPH?!? Wow that is insane! One of my lesser goals is to cause my passengers to **** their pants when I "show them the fury" . I do feel that I have the ***** for this kind of performance but I will definitely have to learn how to drive it safely first. The fastest car I've ever driven is a stock 2000 Trans Am. I got it up to 150 out on a local country road and talk about a rush! . I know that stock LS1 is NOTHING compared to what I want to do so it'll definitely be a big change.

BTW, what do the Hyabusas run in the 1/4? I found out that the Yamaha R1 will run low 10s@13x.

Thanks again,

You will need right at 1000 rwhp in a 3600 lb car. You realize you would need a parachute if your car does trap that fast?

The only way I can fathom you doing it is A LOT of money into cylinder heads and a turbo. A set of heads like SB2.2, GM High port 18* or a set of 12* or 14* Pro Topline heads would be a good starting point if you are doing it with a gen 1 sbc, and you would want a cylinder head that flows like crazy on the exhaust side, which all of these do. Also, to make that kind of power reliably, you will have to spend some serious cash on a bottom end, and I am not even sure that the parts you will need to hold up to that kind of power will last in a daily driver situation. A JE turbo/nitrous piston, billet steel connecting rods and a forged or preferably billet crank I would think would be a minimum, but like I said I dont know how these parts hold up to long doses of low RPM grunt work and idling in traffic.

To be honest, I dont think it is a realistic goal. Now if it were a weekend warrior I think it would be more feasable.

 

Start with 140mph and work your way up. You'll need a tough shortblock. I personally would go with a 355 and go with a T88 or 91mm if you can fit a big frame in. Go with a set of large runner heads, 220CC or more and a nice custom solid roller.

Well, maybe it doesn't have to be an every day driven car. I do have another little beater that I can drive around but I would rather drive the Camaro. I didn't realize that a parachute is required for 150 MPH trap speeds. Can you imagine the look on the face of the guy driving the Cobra next to me when he sees my parachute?

I am by no means a know it all about performance but why wouldn't these high performance forged parts hold up under normal driving? In a normal car it is obvious that the less you "abuse" it, the longer it will last but please educate me on forged internals. I'm not trying to be a smart ***, I'm just wondering what is so different about the forged parts.
Thanks again,

If you ever drove/saw a car that went 150mph in a 1/4 mile you wouldn't want to drive it everyday. 120mph is "pretty" fast. 130mph is stout. 135mph is sick. You get the idea...

I think you're starting with the wrong car to get 150mph. I went to the Thunder Shootout and watched a $200,000 dollar race car (Ronnie Duke) run about what you want - high 8s on boost + juice (not 100% he was spraying...pretty he was though).

You guys have been very helpful. I've lowered my sights a lot and what I would like is a reliable street car that will run 135 or so in the 1/4. Jason Dellinger, featured in GMHTP, did almost exactly that only he ran 138 with minor problems. I would like 150 but I don't think it is reasonable for me to spend all that extra money to hit 150. I'm sure that the Cobra next to me will think that 135 in the 1/4 is plenty fast enough.

 

I don't see why 140 and daily driven would be out of the question. Heck my inline 6 supra will trap about 140 once I swap the single in. Also my buddies 95 single supra is trapping 144 with bone stock motor except for cams. We have more cubes, equal weight. Run big heads, smaller cam and big turbo, don't see why 140 wouldn't be partially reliable and streetable.

I agree with Jose, I would think that it would take a lot to pound the rings out of my block, assuming detnation doesnt occur. Its not like we are making this kind of power on a little 4 cylinder. I drive my car every day during the week and do most of the racing on the weekends. My last motor lasted close to 15,000 miles and was still running strong until that damn factory oil cooler clogged up. I think I could get more then 30,000 before I need a rebuild, but I guess only time will tell. Even if I do need to rebuild it every other year or third year, a freshen up is fairly inexpensive.

I say build the car with the intention of going 150mph, meaning put a big turbo on it. If you decide you only want the 135 trap just keep the boost down.

 

yes, very possible. Send me your car, ill garantee 150mph traps and perfectly streetable. (and no, I am not kidding)

 

Ahh yes, Jordan. I do believe you because I have seen your race videos and you guys pulled away from that LS1 heads/cam camera car like it was on the brakes. I am very interested so I will definitely keep you in mind. I just need to figure out what I want to do now. Thanks,
TJ

 

you shoulda just bought my car, I would given you your money back if it didnt trap 150!

hell, i could put the car back together for you ;-D

 

link with that turbo ls1 race?

 

sleeper, dont see how you can hook up those ponies with anything short of a 12" slick in 5th gear on the street... i am baffled.

at only 630rwhp and 670rwtq (92 octane) my car peels out third from a roll on 295 drag radials... what do you do to hook up and sucessfully floor it on the street!?

call me a poor judge of character flex nuts, but im going to assume you have actually never been in the presence of a car that has done 150 in the 1/4, much less an f body.

there is sooo much to the puzzle that you make a trip somewhere and have a look at a car that is actually doing it to grasp the gravity of the situation.

as it appears you have claimed no knowledge in the f body forced induction area, or even powertrain. i REALLY hope you do the right thing and 'learn' on your stock motor with a nice used supercharger or turbo kit and make the baby steps that someone in your position needs.

everybody wants to go fast, easy and cheap but it just doesnt happen.

 

so how did the above take place?

 

I see what you're saying about me not knowing how fast that is. I don't know how fast that is. I would just tinker with the car myself but I really don't have the time to do extensive work and complete it before i'm an old man. Plus, I want some expert like you guys to pretty much do it for me or sell me a car that already has this kind of work done to it. You guys are the extreme performance enthusiasts on this board and you have experience. I know that I can't gain experience if I don't do it but I want a blazing fast car pretty soon, then I'll attempt some major work myself when I am older and have more time for this awesome hobby. I used to mess around with the car in my sig but I just didn't have the time or tools for major work. The garage I have is barely wide enough for my car to fit in, let alone get under, lol.

After seeing some of the replies here, this project will probably cost somewhere between 25k and 200k so I may either have to just settle for less MPH or wait longer to be able to pay for it.

All I know is that I really, really want a blazing fast 1/4 mile time because I want to be able to tell my friends that it will bury the speedometer in the 1/4 mile and then proceed to make them **** their pants while I show them. Having said that, I don't know how fast that is. I don't even know how fast 135 is. If I could accomplish damn near scaring my passengers/friends when I floor it, I'll be happy. If 135-140 will glue them to their seat with an "oh $hit!!" look on their face then that will be fine. I just thought 150 sounded better because I have never heard of an f-body running that fast. After hearing you guys, I think I know the reason for that.

Please describe to me the SOTP feeling of a 135-140 1/4 mile time. As I said earlier, the fastest car I've been in is a stock 2000 Trans Am and I was pretty impressed with that. If you have any vids of a 135-140 MPH pass I would love to see it too.

Don't get me wrong about the whole thing because I really do love working on these cars. It's just that I want a fast car in the near future and If I worked on it myself it would take too long for my liking. Thanks,
TJ
