Last night I got off from work the same time as my friend so I thought it would be fun to test my car against his on the freeway. Let me give you guys some background info first, we are both in the same car club and we know eachothers mods. My car is a 91 z28 with a L98/700r4 and a Vortech S-Trim V1 supercharger @ 6psi. My friends Supra is a 97 TT/5speed with a single turbo conversion and alot of other mods. I dont know what turbo he is running, but I do know he just upgraded from a PS67. I haven't dyno'd my car so I dont know how much power I'm making, but my friend has dyno'd his Supra and he put down 701 whp @ 30psi (race setting). On the street he runs 1.6 bar (22 psi) and estimates around 600 whp. He has smoked sportbikes on the top end! Needless to say, I knew I wasnt going to win, but it was going to be a fun test anyway.

First run I got completely owned. He caught me off guard though. We were on the onramp entering the freeway and he just gunned it. I dropped it down into 'D' but it didnt matter anyway. By the time I hit 100mph he was already about 20 car lengths in front of me. Talk about being smoked!!!

Second run I did a little better. This time I caught him off guard. Called him on my cell and when he answered I gunned it (LOL!). We started at 65mph. I dropped it down to 'D' and floored it ... pulled on him ... and kept pulling. I couldnt believe it!! He caught up to me at 140mph so I shut her down as he blew by me. Talking to him on the phone, he said he left it in 5th gear but I was still pulling, so he downed it to 4th and caught up. When he passed me at 140 I estimate he was going about 10 mph faster and still gaining speed. Man his car can move!!!

So when all was said and done, I really didnt prove anything but my car did alot better than I thought it would. I wanted to race him for two reasons, first so he could compare my car to a blown LS1 he raced on the freeway a few months back, second so he could compare the TPI setup to the HSR setup I plan to do soon(before/after). He told me my car has alot of potential (feels good comming from a guy pushing 700hp). Next time we do it I'll have my new mods done (StealthRam, Injectors, 749 ECM Engine Management, 6 Speed) and we'll catch it on Camera. My friend with the Z06 said he would like to run with us too the next time we test out my top end. I'll be sure to catch it on video.

 

good runs!

that sounds like one mean ride you got there! i know a few guys over at www.corvetteactioncenter.com that live in hawaii and like to run. they run at some drag strip out there i don't know which one but goto the site and look up hawaii-5lo and he can give ya some info if i don't catch this thread again maybe you guys can all hook up and have some fun!

i think there are 3 or 4 of them guys on the vette site that hang in hawaii. not sure which island though.

 

hahaha :sillylol: :sillylol:

thats some funny stuff...sounds like sumtin i would do. nice story dood. i been spanked by a few supra's like that.

 

Crazy, sounds like you were dropping alot of "D"s. How so you think you would have faired with a 5 speed in your hands??

 

hey man you gotta do what ya gotta do lol...

sometimes your only advatage is takeing there attention away from the wheel

 

Yups, gotta do what ya gotta do, especially when racing a 600+ hp Supra!! LOL! I dont think I would have done much better with a 5 speed. The gearing would have been better for sure, but the thing really holding me back on the top end is the TPI intake. Even on boost, the TPI starts running out of steam around 4800 rpm. Next time we race I think I will supprise him, but I'll probably still loose. My next set of mods should put my L98 around 450 whp with a redline of 6,000 rpm (stock heads, internals, and crank). And the 6 speed I want to swap in will allow me to choose a better gear for freeway racing. Still, I dont think I'll beat him untill I swap in a better motor. I'm leaving the L98 heads and internals stock because I want to save the L98 block as a backup for my other Camaro. Future plans for the 91 z include a high revving SBC (377 or 427) on boost. Maybe when thats done I'll give him a good run for his money.

 

Good runs....

But wheres the VIDEO!

I wanna see some nice daytime races, Hawaiian style...

 

Me too, I want vids

 

Them some mean cars your driving over there. I was stationed at Kaneohe Marine Corp Airbase, where you guys putting out 140 mph runs over there, most hgwys I remember were either to full of traffic or to small. Maybe on the back side out with the pineapple fields or something. That must be the Supra that beat the Ferrari in another thread you had Hawaiin!

 

screw that.. I wanna see CrazyHawaiian do some drifts!!

 

Yeeyah!

 

Try running the Supra at a slower speed next time.

If you can hook, you should be able to take him in the 1/4. If the Supra is running at 30psi though, you will have your hands full.

 

Good races


I would like to see what you two would do from a stop.

 

This happened on a 6 lane portion of one of the main highways @ 1am. The road was completely empty, so at least we were somewhat safe about it. I promise I'll have some video soon. I finally got a Mini DV camera and the capture card so now I just need to practice with Adobe Premiere. I'm going to make a vid with only 3rd gens doing crazy stuff (but racing other kinds of cars, and yes drifting! hehe). There are a few nice 3rd gens here in Hawaii.

BTW, my friends Supra runs a 11.3 but I forget the mph. He's got the launch down, usually cutting a 1.7 or if the clutch dosnt slip a 1.6. The scary thing is that its not even fully tuned yet, so I do think he will be in the 10's soon. Here's a pic of his car. Here's a pic of my car. We'll be hitting the dyno pretty soon. We're going to rent it out for the day for the club. I'll be sure to let you guys know what we dyno. I think with W/B 02 tuning, my friends Supra will put down over 800 whp. I think with my ghetto rig blower setup I'll put down around 350 whp. I plan to dyno again after my next set of mods and I should be putting down around 450 whp @ 6000rpm.

 

Hey I don't want to say anything but you seem to have turned the camera crooked when you took the pic of his car. Might want to look into that.

Those Supras sure do make some crazy power. The few guys who actually fix their suspension for drag racing while modding their cars put down some great numbers but most of them are just dyno queens. Still...breaking the tires loose flooring it at 80mph has to be pretty crazy.

 

I like the cell phone distraction technique- very inventive!

 

i would never race an import that i knew was goin to beat me. i wouldnt live to hear the end of it.

 

g0d damn your car is sweet man. what color is that? laser red metallic? how much did that cost you (if ya dont mind me asking). that looks sooo nice man. i could only dream of my car looking that good.

 

screw the paint, I'm looking at the rims! lol, got any other shots of those?

 

I thought supra TT were 6 speed not 5

 

AHHAHAHAHAAAAAAAAAAAAAAAAAAAAA!!!!! thats some funny ****.

 

Hehe thanks guys. The paint is 2002 GM Sunset Orange Metallic. The previous owner of the car had it painted, so it didnt cost me anything. I dont consider it a professional paintjob (alot of flaws), but I guess I cant complain. Its a nice color but honestly not a color I would have picked if I was paying for it. But now that I've had it a while its growing on me. The wheels are Boyd Coddington Tuned 18x8 front and 18x9.5 rear. Here are the only other pics I have for now:







I will get some more pics when I finish a few things.

 

man I love those rims. Car looks awesome man.

 

I agree, the color and the rims are beautiful.

 

those rims are pretty cool...the only thing i dun know if i like is the lip....fromt eh front and back side angles they look like 15 in rims almost cuz theyhave that double 90 lip styles like old chrome rims...lol....but awesome car nonetheless(the rims bother me a tad everytime i see the pic of your car )..i couldnt shut myself up this time i guess

 

OMG, you didn't like the Sunset orange at first?!? What's wrong with you? j/k, that is my fav. color on a 4th gen that's for sure. Good luck with the 6-speed, *** knows your 700 won't last very long with the power you've got. My only suggestion is to get rid of the stock heads whenever you can. I doubt you will ever see 450rwhp with those, unless you add some juice to you boost. Anway, great story!

 

i know this is old, but i woulda wanted an even start.....
whats the point of testing it if he takes off 20 secs before you or you call him on his cell then he starts in the wrong gear....
seems more like fun on the street but ya didnt really get a good test in

 

I know what you guys mean about the lip. I also like a completely flat lip instead of the beleveled lip. I should have done more research before ordering. I think Boyd does give you the option of a reverse dish and thats how you get the flat lip. Maybe next time hehehe. And next time we race I will be sure to get an even start. I also want to catch it on video. I knew I was going to get smoked last time we raced so having an even start wasnt really important to me. Seeing him fly by me at 140 mph was what I wanted to see LOL! The only reason I didnt like the Sunset Orange Metallic was because of the maroon hue. I like oranges that are more yellow than red. The paint on my Z looks really red sometimes. I owned a maroon red 89 RS for years and I just hated that color. I always told myself my next Camaro will NOT be maroon. So when I saw the maroon shade in the SOM it made me not like the color. Of course it probably also has something to do with the 1/2 azz paint job the previous owner had done. There is still coats of maroon red under the SOM (found it when I cracked my front lip). This is probably adding to the maroon hue. That one pic of my car next to the orange Z06 really shows you the difference between a yellowish orange and a reddish orange. The paint on that Z06 is Lamborghini Orange, really yellowish. I like it alot!! Thanks for the tips on the heads. I totally agree. Whats really interesting is I'm finally really close to selling my house. Open house is in 2 days. I've already decided to use a percentage of my profit on my cars. So it looks like I'll probably be ditching the 350 completely. I'll use the 350 block as a backup block for my other Camaro (the drifting one). I want to swap in a 427 SBC and boost it! I'm putting $10k aside for the motor. Next time I race that Supra, its going to be even starts and its going to be recorded. I plan to beat him!!

 

sounds like a killer plan!
congrats and good luck

 

World Racing recently released a 454 SBC, putting out unbelievable numbers! If I recall, the price of their crate motor is 'around' $10,000...

This above crate engine combined with the right gears, as well as stiffening up the chassis and reducing weight, will absolutely DESTROY that Supra TT.... even without you resorting to boost!

Import's are quick because their light, and if you can match that car's weight advantage.... then add enough stroke and gearing to your's, it'll be over. Hands down!

 

Supra's are not light cars, from there 3rd gen run into 4th gen they weighted in at 3400lbs, which is right around 3rdgen average weight.

He just need more power!!!

 

I don't think Street Lethal did his homework. From a roll Supras are fast...very fast...especially when modded. They can easily reach 1000hp with stock internals (or so some of the websites say, who knows for sure) The 454 sbc from my vague recollection of the article I read in Hot Rod or something several months ago was going to be around 650hp 540tq which is awesome, but whether it would be sufficient to take out a modded Supra is another story and could be dependant upon many factors.
The problem with Supras is they can't hook worth a damn. My friend wanted to show off how fast his Supra was but there wasn't a dyno around to race on.

 

Street Lethal didn't do his homework? That's a laugh indeed! I run all the time here at Raceway Park in Old Bridge, and if you ever find the time.... you're more than welcome to come down and give me a run in any Supra TT you, or any of you're friends can get you're hands on.....

We dyno car's all of the time over here, and Supra's make their power at much higher RPMs. I myself have a 454 Big Block in my 86 IROC, that makes close to 600 lb ft of torque at way under 5000 RPM. If I ever decide to boost it in the future, it'll toast any Supra TT you can find.... with traction of course!

My IROC dip's into the 10's WITHOUT 'turbo's', nitrous.... or supercharger! What 'Supra' can do that? "I didn't do my homework...." that was histerical bro!

In fact, we're going racing tomorrow, so again, you're MORE than welcome!

 

Street Lethal lacks basic reading comprehension. No one cares about all motor, it's how fast you actually are. I find your violent verbal outburst very amusing. You do realize the average mkiv supra is heavier than your car, don't you? "Lighter" indeed.
What do you trap at and how well does your car run stoplight to stoplight? What? Oh, yea, this is the STREET racing forum.

 

For you're information 'Mr. Moderator', that was NOT a violent 'outburst', and if YOU read my post's in that manner.... then that reflect's on you, not me......

(maybe I should have posted some more smiley's)?

As for my car.... it is street legal, and I have an inspection sticker to prove it. I was merely inviting you down to race, sorry if you found my little 'challenge' violent, I was just trying to make a point, which is this;

ANY car can run in the 9's, and ANY car can run 200 MPH....

What matter's, is, who get's there first.

A naturally aspirated (non-turbo) Supra, is not even in the same league as a naturally aspirated (non-turbo) IROC with a 454....

'Whatever' mods the Supra can make, SO CAN THE CHEVY!

That's my point, bro! Don't take my word's the wrong way.... I just have a habit of using the '!' too much, but I post in peace...

 

As far as I know, 'talk is cheap'. I could throw number's at you all day long..... which is why I'd rather prove my talk 'via' the track.

This is a NICE invite for anyone who wants to run....

.... and for those who bring their Supra's, don't forget you're wallet's!

That was a joke BTW.... which I 'now' suddenly feel I must mention ahead of time....

 

Indeed, and my original posting was simply pointing out that Supras are highway monsters. They generally don't do well in the 1/4 mile due to their IRS etc, but they are super duper dyno queens making crazy hp numbers to the wheels.
I was simply saying that the 454 sbc probably won't be up to the task with "only" 600 or so hp at the crank although I'm sure it will absolutely destroy the Supra from a stop. I'm sure you've seen Supras at the track trapping 140 with 12 second timeslips and other cars trapping much much less while having quicker e/ts.
My post had nothing to do with your car or you in general. No one said a single thing about n/a supras either; TT means twin turbo from the factory. Don't take things so personal next time, I was making a generalization about an internationally recognized performance car; don't take it as a personal affront.

You still didn't answer what your trap speed is, what your setup is, and how much you paid to get an inspection sticker with a cage and racing harness.
Stop taking things personally 'Mr. Senior Member'

 

I found the motor I want here locally. Its $6300. Crate 427ci SBC that revs past 7500 rpm. Leaves me with $3700 to buy the rest of the setup. I know its not enough ... I'll probably end up spending closer to $15k (want to intercool and everything). I know big blocks have alot of torque, making them great for the 1320, or if they're aluminum, a short roadracing course. But they are not something I would use for top end freeway racing. Its just something about having a 3,000rpm to 7,500rpm powerband on boost. Its a different experience than having ungoddly ammounts of torque at low RPM's and a 1,000rpm to 5000rpm powerband. Thanks for the ideas though.
