i have read of a couple can anyone confirm?

matty

i am looking for personal experience, what you have read in magazines, and what you believe the range is for a normal stock rx7 to run the 1/4 mile in.
I usually give 13.5-13.9 range as normal...

thanks for the help!

Sure. 99+ Stock RX-7's run 12's off the factory floor.

The lowest published ET I believe was 13.9@99 by Motor Trend. There might have been a 13.8 but I'm not sure.

What you have to remember is these mags have pro drivers that are experts at launching cars and they have a new car they can beat on all day long over and over again to get the best time.

Most totally stock FD's are lucky to ever break into the 13's at the track in total street trim with stock boost. Alot will say they have. Alot will have friends that ran 12.xx "totally stock" but the reality is mostly 14's from personal experience.

matty

thats it,,come on get involved..i believe i have seen quicker times in magazines..anyone else?

racerfoo

i've heard high 13s....all i have is downpipe/gutted cat and i have beat 02 SS and 02 TA ws6 (auto). barely beat them, but those run low 13s i think

The mags say 13.7 to 14.2 when new.

13.5 is a dream, only 1 or 2 documented cases of that fast (or faster) with a stock car. People quote those fast ETs all the time but in reality no one wants to admit almost every other FD can't do it.

I ran a 13.9xx @ 99.54 mph when my car was stock with a passenger. 93 R1, 60' time was just over 2 sec.

And you believe this why?

ZeroBanger

I can tell you Jesse from Okanawa says so!!!!!!

Its not hard to believe that a 280 HP 2002 RS model can run 12's 25 HP and an open exhaust can put you high 12's.

but I have no evidence!

Because I have a friend who owns one, and has done so.

I ran 13.36 absolutely completely bone stock down to the Expedia SO2's with dealership air pressure in them. This would have been in 1993. I was pretty mean to the car in doing it as in i didn't practice gentle shifting etc.

Who are these pro drivers the magazines have running high 13's? They suck. Pay me and I'll drive.

LMAO. You have a slip, just curious? That's the fastest time I've heard. Not doubting at all, I know who you are and your history, just curious really.

I still find it hard to believe 12 second FD's rolling off factory floors. Don't get me wrong, 12's is not hard at all. But from a factory FD, even the RZ's, I'm rather skeptical.

Would you mind telling us what the mph were, the 60' time and where you ran it?

Chris

Would have been run at Rock Falls Raceway in Wisconsin, just across the MN border. As for MPH and 60'. Hrmm just a guess but I'm thinking between 99 to 104 mph and high 1.8's for 60'. Okay I just dug into my folder of time slips. Hrmm 8/14/94 ran 11.58 @ 122.00. Heh, this must be with my crush bent exahaust on it. 10/9/93 13.202 @108.48 with 2.22 60' : ). Same day 12.75 @109.19 wotj 1.97 60'. Ahh cool thanks for making me dig. Found my 12.677 @110.48 with 2.015 60' from 10/9/93. That was with just a crush bent replacement for main cat and muffler.

Ahhhh! found it. Has a note to my brother on it too : ) Marty this was my 1/4 time!

13.337 @ 105.62mph 2.212 60 foot time and a .584 RT ROAR on the RT. 1/8th mile was 8.695 and this all happened on Sept 25th 1993. Thanks for the trip down memory lane. I have hundreds of time slips. Poor car. heh.

Please note none of those are corrected to sea level times or MPH. Corrected would be 13.337 >>>13.22 @ 108.22

ZeroBanger

You are to RX7 drag racing what nocab72 is to RX7 highway racing so I can speak for all of us when I say you are our hero. Now with that said....

HOW THE HELL DID YOU RUN A 13.3 WITH A 2.212 60 BONE STOCK.

Thanks.

Kevin,

What were the outside temps?


Jeff

Kevin T. Wyum

Heheh you like that 60' huh? Chuckle I agree I'm pretty surprised I pulled that time with such a shitty 60'. I will say I was mean as hell to the car, banging gears and skimpy with the clutch. I have heard of someone else running a 13.3 something I think in 1996 or something I assume they were driving like me : o. Actually now that I think about it the 60 foot helped a bit with the ET which goes against conventional wisdom. The cars bog severely if you hook hard in stock trim and I think a lot of wheel spin actually helped keep me in the powerband. The MPH was pretty nifty which fits the tought. Anyway that was almost 10 years ago. : )

Kevin T. Wyum

Not a clue on temp, it doesn't print out on the receipt. Is there any kind of weather archive that would have that? It's right near Menomonie (spelling) WI and was exactly 1:09pm 9/25/93. Let me know if anyone finds an archive.

Kevin,

I honor of this amazing time you have (considering I have a boat load of mods and run 16.4 with the same car, check my sig) I think I may order a M2Large Intercooler this weekend. I was gonna wait till after the new year, but I heard that you designed that IC, so it must be damn good!

turborotarypower

my best time was a 13.5@101 mph with a 1.9 60' and about mids 90's heat,but my car had many problems including lower than stock boost.

MI_SS_IL

That wasn't a stock run was it?

You think your running faster than a pro driver with a 2.2 60' time? No offence, but 2.2 isn't anywhere near exceptional. Something else doesn't make sense to me, most guys are running better than 2.2 60' times bone stock and they're hitting 13.9's and high 14's. Does your car just have more power on top end than every other stock RX7? A great e.t. comes mostly from a great launch ... you don't have the great launch, but you have the great e.t.. Something doesn't add up. This is a bone stock run? Was this ever repeated at a different dragstrip? I have a time slip that shows me running consistent 109mph trap speeds when my car was practically stock ... I found out later the timing equipment was off in that lane, although it was consistent. You'll have to forgive me if I sound skeptical because your times do not add up. If you had come on here and told us you had a 1.7 60' time then it would be more believable, but 2.2 with a 105mph trap does not equal 13.3 in any other RX7 I've ever heard of other than yours.

It was bone stock?

Chris

ZeroBanger

Chris....

I got bad news for you......

THE RX-7 CLUB KNOWS ABOUT YOU!!!!

MI_SS_IL

Bring 'em on Zero. Those times do not add up and you know it. 2.2 60' times and low 13's bone stock? C'mon man, that ForceFed guy we were talking about was running 13.5@105 with a 1.8 60' time and that was hard enough to swallow, but his exceptional launch fit the e.t.. 2.2 does not fit 13.3.

Chris

That was an inside joke, btw.

As far as his times, remember this is a turbo car, not n/a. My mechanic has built and rebuilt rotary engines for more than 16 years. He has told me that right from the factory (bone stock off the showroom floor) he has seen RX7's with 8 lbs of boost and RX7's that run 12 lbs. The 7 was designed to run 10 lbs. There are differences in the cars. With that said, my opinion (at the moment cause I change it so damn often) is that Mazda designed the car to be a high 13 second car, BUT there are some that boost more than stock. Nobody would know this cause mazda does NOT include a boost gauge.

Now if someone ran those #'s and had 12 lbs of boost, that is very possible. I'm NOT saying that is the situation, but there are other things to consider. I would put money that forcefed's car is not pumping out 10lbs either.

Also, Kevin is like the greatest drag racer on this planet too. Consider that before you call BS (which I know you have not yet).
