CHeck out my sig for my mods. But i'm a college student at Clemson for those who are familiar. In any case the fastest car at school is this zr-1. From what i can tell its stock, yet he seems to think he can beat me. ANd he "knows" he can "crush" me on the top end.

Any thoughts? I would think that i could take him no problem

Anybody have any idea what my top speed would be with the stock 5-speed tranny. I assume i'm limited by gearing, not by power

Specs on zr-1: 1/4 mile in 13flat, 3500lbs, top speed ~ 180

Oh i dyod w/ 330rwhp @ 10 psi and now i'm running 13 psi, so that should give you some idea what kinda of power i'm making.

THanks for any input guys

Your T-78 will actually help you with a top-end run. I remember a post with someone with a T-78 running like 20 psi racing a Callaway twin-turbo and killing him by 6 lengths to 150 - those Callaways are extremely fast too - much faster than a ZR1. ZR1s are more top-end cars but you should pull him with your single.

This isn't a kill.

haha, you have a fully built single turbo motor and your worried about a vette! just in case turn it up to 15 and smoke him real good. you should be pushin the low 400s with 15. if he even keeps up with you then he aint stock, eitherway though u win.

should not have a problem with that T78.....

must be nice being a college student with a new bimmer and a modded out R1! a little extra inheritence cash maybe?

Freaky Monkey007

Well clemson is a preety big college...So im sure there is plenty of everything there..

What year is the ZR1? Weren't the '91's the fast year, they came with the Mercury Marine engine?

I've seen times of 12sec 1/4ET's for those, it should be a good race though.....turn up the boost to be sure!

yy4u

nope i make my money online gambling....but thats a long story - i turned 6 figures last year, but now i get the rude awakening of having to pay taxes. My dad drools over my cars; he doesn't buy them for me. Just thought i'd clear that up, i hate when people think my parents buy everything for me




Oh and its a 93. He says its stock, he beat a 94 FD TT with full exhaust and no other mods. He beat an MK IV supra TT, but not by much. Supra was basically stock, a few bolt ons but stock turbos and engine i think.

He's soooo cocky too, i'm so ready to hand him his ***. I tried to explain why i would win, power to weight ratio, drag coefficient, etc. but he didn't like the physics lesson and now he's all pissed off. I really hope i don't miss a shift or something retarded like that, i'll hate myself, and he'll never give me a 2nd chance.

NickSimcheck

yeah the spoiled kid came to my mind at first when i saw you have a 330i too, but now i know your just a lucky basturd i wouldn't be scared if i was you, just go out there and give him a run for his money... if he only had a little lead on a supra then you'll smoke his ***... just take it nice and easy and don't **** up and he's now a **** face. if i were you i would get a few friends in on it and have then listin to him bs on how much he will spank you then race him and then he'll look like a real jackass.

You will take him. I also own a ZR-1 and while they are a fast car, they are not fast as a single turbo RX-7. If you guys do a top speed run, it may be close. You will be faster getting to your top speed, but I am not sure as how fast the gearing will allow you to go. A stock ZR-1 can push around 180. Good luck.

you need to get your t78 tuned better, 330 hwhp, c'mon that is nothing. get to a dyno and tune that PFC, and turn the bvoost up to 15 where it belongs. you shoudl be turning at least 450rwhp.

also, the 3rd gen is not limited by gear but by power, you should hit 200mph.

yy4u,

I agree, you should be able to humble him like an M1 tank crushing dog ****...and make sure he hears about it for the next year or so....****** like that need to be bitch slapped...ZR1, ha, what a joke....archaic pig

are you running from a roll or a stop? if it's from a stop, might want to bone up on your launch technique

I'm not sure about KZ1s claim of 450 hp, but 400 to 420 at 15 psi is highly likely, enough to spank a ZR1 in any case

oh, didn't mean to insinuate you were a rich daddy's boy, just curious, I figured it was the stcok market if not inheritence money, but I think the golden days of easy pickins like internet stocks (the ultimate gimme) are over for awhile

it still kills me that Yahoo stock went from like $20 a share (or less) to $420 over a two year period....ahhhhhhhhhhhhhhhhhhhhhhhhhhh....kicking myself repeatedly for not seeing that coming...what is it now, $20 again?

yy4u

330whp was only at 10psi, i plan on getting it dynoed again March 31st, and i'll have the boost at about 14 or 15psi, but i dont' plan on going over that until i add 1600cc secondaries w/ custom rail, a separate boost controller (probably apexi avc-r digital), and a new map sensor, then i should be fine to go on up towards 20+psi with higher octane fuel.

It was tuned professionally, and i don't have the knowledge to change such things as engine timing on the dyno. I dont' really know what to look for.

What do i look for while dynoing - what adjustments should i make. I'll get an hour on the machine, i want to use it wisely.


Also, KZ1, are you sure they aren't limited by gearing? I find that hard to believe with only five speeds. Do you know what the gear ratio is in 5th gear? I'm sure i could look it up but if you know it off hand...

jimlab

With the stock tires, the 5-spd. manual cars are gear limited to 200.7 mph. Moving to a P275/40-17 in the back raises that to 207.2 mph. Those numbers are @ 8,000 rpm in 5th, by the way, with the stock 4.10:1 differential.

thatoneguy

I'm assuming you just got your T78 FD since you don't know if you can beat a ZR1 or not. Anyways, the top speed on a FD is around 200mph with the tach at 9000rpm I think.

...ZR1, ha, what a joke....archaic pig



Come on now, please.

#1 "archaic pig" The last year of the ZR1 was 1995. For some reason that reminds me of another car that was last seen sold here around the same time.

#2 "ZR1, ha, what a joke" How can this car be classified as a joke. 405hp, 32 valves, 4 cams, gets excellent gas mileage, is RELIABLE. It was making big horsepower numbers when other car companies couldn't due to emissions and ecu battles. It handles like a dream. Has 3 different suspension settings that is adjustable from inside the car.

Compared to todays cars, it may not be as impressive, but neither is our beloved RX-7.

BTW, of the two cars, I do like my RX-7 much more.

KZ1

a stock ZR1 may give a stock FD a run for its money, Man with single turbo you are going to destroy him.

You have a power FC, what do you need and AVCr for?? you don't really need extra boost controllers. Get the dataloggit, then you can really do all that stuff. that is the first step, do it before dyno tuning.

t78, is one of the big boys, have fun tuning that thing!!!

compared to a Z06 it is an archaic pig....the C4 chassis is antiquated relative to the C5

I FEEL UR PAIN!!!!!! I cld of bought my FD in cash w/ the money I lost 2 yrs ago. The market SUX!

FD3S LIGHTNING

my 2 cents: Kick his @ss and keep up the FD reputation

dimaguila1

howbout this one....back in 97 I pulled all the money I had out of the stock market to pay for our wedding. The timing sucked! Just one example for ya'...

ipo - verisign 200 shares
$2.50/share = $1000 investment
sold it at $20, made 4K

A year later the stock split 2/1 twice!!
That would have given me 800 shares, ultimately went to $250/share. If I would have gotten married a year later and sold my stock then I would have made:

800/shares @ $250/share = 200K!!!!!!!!!

You play, you pay! That would have bought me a couple nice FD's!

Will the Power FC control boost? Several people have recommended a separate boost controller, because the only way to control it right now (as far as i know) is the imprecise manner of adjusting the screw in the top of the wastegate, which requires getting the car on ramps and crawling underneath, i'd much prefer the push of a button, to this long and time consuming process. On several occasions i have posed this question over in the single turbo forum and everyone has told me that you can't control boost with the Power FC, even though the PFC has a "boost" setting, and the guy i bought the car from still hasn't sent me the manual for the Power FC, so i haven't been able to find these things out for myself

KZ1

I don't have a single so you are porbably right about the inadequecies of the power FC controlling boost for your application. I know for twins the PFC works the same way as any boost controller. and works very well. I assume the single guys know what they are talking about.

However, I believe that the new dataloggit will solve that problem, they give you much more extensive control for the PFC. I know PFC will control non-seq, I have no idea why it woudn't do single, porbably because of aftermarket WG. Check with dataloggit, I am sure it fixes that, if it doesn't they will porbably make it for you.

hope that helps. BTW, the manual to the PFC is posted in the power FC section.
