RX80-TX... I have seen a few of your posts, but just now noticed you were from Richardson. Were you at the last ROAD meeting? I can understand frying the clutch... have people had problems with the tranny?

PA BATMOBILE

Launching at 7k a bunch of times is hard on your clutch. Don't power shift er any of that crap, its hard on the syncro's (trust me i killed my civic tranny like that; and yes i know, i know)

RX8-TX

Yeah, I was there. I think I was the last one to arrive with my wife.

I know that Judge Ito had problems with his transmission. Look the only sticky on this forum.

Well, I said I would come back with a full report, and that is what I intend to do. I got there Friday night and started checking everything out. I ended up running but only picked up 2 of my slips... my best and my worst. The first time up I was going to line up with an S2000. They had the left lane blocked, so we ran solo. I am completely stock, and left the tire pressure alone (stupid). I took off from the line and the tires just spun, then began to hop. Finally I caught traction about half way through 1st and it felt pretty good. I ran a 9.93.

The next time around I was going to line up against a BMW 3.25. Once again something happened. As I went to line up, I got staged and began to rev her up. I looked over in the other lane and there was a neon srt-4. The same car that earlier smoke a 'vette. Mopar sickers all over it..... Anyway forget him, I ran a 9.92. Everything went just like the first time.

The third time around was my worst. I finally got lined up with the BMW. The light turned green and I tried to feather the clutch to keep from hopping...Should have adjusted tire pressure...I didn't spin, and I ran a 10.34. The BMW ran a 10.54 so I felt bad, but at least I won.

Next I lined up with the S2000. This was some asian guy that put a supercharger on. I saw him running 9.3s to 10.0s. He wasn't very consistent. We lined up and I tried not to feather too much, but still not spin. I ran a 10.11 as the S2000 ran a 10.00. I felt terrible.

Then I was on my way out and an Eclipse w/ turbo decided to change my '8. I just kind of laughed, then he said he had already blown 2 of them away... so I took the opportunity. Everything felt better. I had my best take off (still not right, but better) and ran a 9.88. I had a 2.31 second 60'. The eclipse ran a 10.54, then said that was his best time ever. Didn't make any sense.

Well, that was my night at the drags. I went Saturday and got the M-Flash. I can definitely feel a better power curve and expect it to help a little. I will have to wait 2 weeks to find out, but will post results.

Sunday I was testing it out and hit about 110 mph and my check engine light started to flash, so I guess I will get that checked out.

S2000's run about a 9.2 1\8 stock.

I doubt VERY much it was supercharged. And even if the track was under elevation it would not effect it since its FI. Even more reason it was most likly not SC'd. And if it did by chance have a SC in it and it was tuned properly to use the SC it would probably be running 8.2-8.5 1\8s without a sweat on street tires.

I don't think anybody is dumb enough to supercharger a car that has under 130 peak torque to the wheels and a 8800 redline, you would be asking for trouble and the lag would be rediculas on top of it.. Only turbos would make sense for small 4 cyl engines.

RX8-TX

Don't you mean the other way around? A turbo would represent a terrible lag, whereas an SC would represent INSTANT tq from low rpms?

I've seen plenty of SC'd stook owners on S2Ki, very few turbo'd

ByeByeHonda

Yeah, I witnessed this SC. It was his first night on the track and wasn't very comfortable with the car. Like I said, he was ranging from 9.29 - 10.01... He didn't know exactly how to drive it yet.

Lawerence

So your level elevation right?

And what was the temp/humidity?


Those times are probable good for low 15s in the 1/4 mile.

Here is a slip from my old nissan specV.

60' ... 2.395
330 ... 6.536
1/8 ... 9.929
mph ... 72.37
1000 ... 12.885
1/4 ... 15.381
mph ... 89.69

Id expect your car to pull a little better in third.

What are your trap speeds in the 1/8?

ByeByeHonda

Well, I don't have a scan of the slip... But I will post the numbers tomorrow. It was 75 degrees and humid as can be. It rained almost all day, then quit at about 7. The races started at 11:00 pm and I started at about 12. My 60' time was 2.31 and my 1/8 was 9.88 at 72 mph. Elevation is 600'.

Lawerence

I thought your best 1/8 was 9.92?

ByeByeHonda

No, I ran a 9.88 against the eclipse, which was my last run. I have that time slip. I'll try to find a scanner. I'll go ahead and post those numbers tomorrow until I find a scanner.

Lawerence

ah I see...
well here is a 9.8 from my specV...

60 ... 2.299
330 ... 6.442
1/8 ... 9.832
mph ... 72.30
1000 ... 12.780
1/4 ... 15.269
mph ... 90.03


And your car definitely pulls better after the 1/8th so you need to get to a 1/4 mile track
i'd say 14.9-15.4

ByeByeHonda

I agree just based on the fact that it feels to pull pretty good in 3rd... and at 72 mph I am not even getting in to 3rd good. I have found a 1/4 mile track nearby, but plan on going back to the 1/8 just as a comparison before and after the M-Flash. I don't know if it will really make a difference or not, but it feels a little more powerful through all the way through. I know the weather will probably be different too, but I just want to see. Then I will try the quarter mile.

Lawerence

you should go to the 1/4...screw the 1/8th.

You get BOTH when you go to the 1/4 mile just judge from that.

ByeByeHonda

True... I will check out the schedule for the 1/4 mile track... It will be a couple of weeks before I go back anyway.

WTF no turbo

14.02 ill try to find the slip.No offence but if the cars you listed are accurate they all sound like high 12 to high 13 cars.Ive seen a sc s2k run a 12.53.
now the 14.02 was a 7500k bomb and i have 275 nt555 on the rear.

RX8-TX

you ran a 14.02??

murix

Actually, in this instance, a turbo would produce better midrange torque if this is referencing a centrifugal supercharger. They do not even begin to make power until 4k rpm. They are fine if you are driving on a track and keeping the revs high but a turbo really is better for making power. Take a look at the powerband on those supercharged comptech S2K's.

RX8-TX

Not a centrifugal, those are dependant on engine speed -both are, but a centrifugal needs more velocity to spool enough, am I wrong?-. I was talking about a -possitive displacement??- where the SC is spooled up from moment your press the pedal...ok, ok I gotta go back and keep reading my book... :D

RedRx8Guy

Keep in mind the S2000 has VERY little torque until after the VTEC threshold. And if I remember off the top of my head peak torque isn't reached until somewhere between 6-7K RPMS! So when you introduce the resistance of a centrifugal supercharger in addition to the VERY LOW torque numbers it produces low range your talking lag and a real crap powerband for everyday driving.

The only way a SC'd S2000 is good is if its a race car and the car will be launched at high RPMS off the line. I can see pulling a 9.8-10 in the 1\8 with an SC'd S2000 if its not launched at a high RPM and just eased off the line, the lag would be torchure! I would NEVER want to drive a SC'd S2000 in my everyday travels..

ByeByeHonda

Oh, and that is exactly what happened in my case. The light turned green and I launched out ahead. The S2000 had no power off the line and didn't catch me until 1/2 way through second. I watched him run many times. Even including his 9.29 he was still sloooow off the line. No power at all. He coulc have got sub 9's if he hadn't been scared (cautious as some people call it)

DKNYJoey

My Last Car was A Pontiac GTP too RedRx8Guy. Boy do I miss that torque! I was Pushin' 300 Horses in that thing! Can't beat American Cars with their Torque.

RedRx8Guy

Thats for sure.. Was your pulley'd too? I had installed the smaller SC pulley and put in an aftermarket exhaust. I wasn't crazy about the exhaust note but one things for sure, no matter what speed\rpm you were at, all you had to do was mash the pedel and whammo, your buzzing thru the RPMs with instant response.

lol haha yea i have to see that to believe it too. nt555? street radials? or track...
